There are many ways to fix the accessory to the plate-like object, and the clip is used for fixing two objects as a structure which is easy to install and disassemble and can be reused. When the fixing is carried out, the accessory passes through the mounting hole, two ends of the accessory are respectively positioned at two sides of the plate-shaped object, and the two ends of the accessory are fixed at the two sides of the plate-shaped object through the buckles, so that the accessory is fixed on the plate-shaped object.

When the device is used, the buckle is moved to the buckling position on the accessory or the plate-shaped object to complete fixation, and when the device is disassembled, the device is moved along the reverse direction of the use to break away from the buckling position to release buckling. Because the structure of buckle is simple, cause the aversion because of the touching easily after the lock to lead to the buckle to break away from the lock department along the opposite direction when using under the condition that the mistake bumped, influence fixed effect.

In view of this, the embodiment of the present application provides a buckle, which can avoid releasing the buckle due to accidental touch after the buckle is buckled, thereby effectively improving the effect of fixing the connection between two components.

Fig. 1 is an explosion diagram of an application scenario provided by an embodiment of the present application, and as shown in fig. 1, a usage scenario of a buckle 3 provided by the embodiment of the present application is described by taking a plate-shaped object as a box body panel 11 of a distribution box 1 as an example, a locked component 2 includes a front panel 21 and a housing 22, the size of the front panel 21 is larger than that of the housing 22, for example, the locked component 2 may be a reactive power automatic compensator, and the like, the housing 22 has a first outer wall 221 arranged at an angle with respect to the front panel 21, two rows of second tooth rows 23 are arranged on the first outer wall 221, and an installation channel 220 is arranged between the two rows of second tooth rows 23. The box body panel 11 of the distribution box 1 is provided with a mounting hole 110, the size of the mounting hole 110 is smaller than the size of the front panel 21 of the locked piece 2 and is larger than or equal to the size of the shell 22 of the locked piece 2, the locked piece 2 can be put into the mounting hole 110 from one side of the box body panel 11, and the front panel 21 and the shell 22 of the locked piece 2 are respectively positioned on two sides of the box body panel 11 of the distribution box 1. The buckle 3 provided by the embodiment of the present application can pass through the installation channel 220 and be fixed in the installation channel 220 along the installation direction, the installation direction refers to the direction from the end of the housing 22 far away from the front panel 21 to the end close to the front panel 21, as shown in the y direction in fig. 1, the buckle 3 is matched with the housing 22 of the locked member 2, and the end of the buckle 3 close to the front panel 21 can abut against the surface of the box panel 11 facing the housing 22, so that the box panel 11 can be clamped by the front panel 21 and the buckle 3 of the locked member 2, so as to fix the locked member 2 on the box panel 11 of the distribution box 1.

Alternatively, the lock 2 is fixed to the box body panel 11 at a plurality of positions by a plurality of catches 3 from the housing 22 of the lock 2. Alternatively, each set of catches 3 is fixed in the opposite direction from housing 22, thereby limiting the movement of locked member 2 in a certain direction, further enhancing the fixing effect.

Fig. 2 is a schematic structural diagram of a buckle 3 provided in the embodiment of the present application, fig. 3 is a schematic front view of the buckle 3 provided in the embodiment of the present application after being mounted, and fig. 4 is a partial enlarged view of a place M in fig. 3 provided in the embodiment of the present application, and as shown in fig. 2, 3 and 4, the buckle 3 provided in the embodiment of the present application includes a body 30, a cantilever assembly 31 and a first tooth row 32. The cantilever assembly 31 includes two opposite cantilevers 310, one end of each cantilever 310 is connected to the body 30, and any one cantilever 310 can rotate or bend in a direction approaching the other cantilever 310 under an external force. The first row of teeth 32 is located on the side of the cantilever arms 310 away from each other for engagement with the tooth openings of the second row of teeth 23 of the locked member 2.

Through the meshing of the first tooth row 32 and the second tooth row 23, the situation that after the cantilever 310 is touched by mistake, the cantilever 310 is forced to be separated from the locked part 2 along the installation direction, and the fixing effect is influenced can be prevented.

Specifically, as shown in fig. 3 and 4, the locked element 2 is provided with a mounting channel 220, when the buckle 3 is used, the buckle moves from a first end 2201 of the mounting channel 220 far away from the front panel 21 of the locked element 2 to a second end 2202 close to the front panel 21, and the second tooth rows 23 are positioned at two sides of the mounting channel 220. During the moving process of the buckle 3, the first tooth row 32 of the cantilever 310 gradually approaches the second tooth row 23, and after the second tooth row 23 contacts the teeth of the first tooth row 32, the two cantilever 310 are bent or rotated in the direction of approaching each other by pressing the teeth of the first tooth row 32, so that the buckle 3 can continue to move to the second end, and the first tooth row 32 is engaged with the second tooth row 23 at a proper position, for example, where the body 30 of the buckle 3 can abut against the box panel 11. When first row of teeth 32 engages second row of teeth 23, clip 3 is secured to locked element 2. The clip 3 fixed in this situation is restricted in the mounting channel 220 by both sides thereof being in contact with the mounting channel 220, and movement of the clip 3 in the width direction of the mounting channel 220 (for example, the x direction in fig. 3 or 4) is restricted. Also, the engagement of first row of teeth 32 and second row of teeth 23 causes movement of clip 3 in the lengthwise direction of mounting channel 220 (e.g., the y-direction in fig. 3 or 4) to also be limited. Therefore, the cantilever 310 is arranged on the buckle 3, the first tooth row 32 is arranged on the cantilever 310, the movement of the buckle 3 in two directions of the locked piece 2 is limited, and the fixing effect of the buckle 3 and the locked piece 2 is improved.

On the other hand, as shown in fig. 3 and 4, the embodiment of the present application provides the clip 3, when the clip 3 is fixed on the locked member 2 by the engagement of the first row 32 and the second row 23, if the housing 22 encounters an external force along the length direction of the installation channel 220, i.e. y direction in fig. 3 or 4, and the external force acts on the cantilever 310 from the first end to the second end, i.e. F direction in fig. 3 and 4_NThe direction is outsideA direction in which a force acts on the cantilever 310, for example, the external force is a thrust force in the direction toward the front panel 21 acting on the housing 22; alternatively, the external force is a pulling force acting on the front panel 21 in a direction away from the housing 22, and all of the external forces can cause the buckle 3 to receive a force F in the same direction_NAnd a force F_NIs located on the teeth of the first row 32, under the action of the external force, the cantilever 310 will generate a bending moment (e.g. M in fig. 4) in an outward direction, so that the first row 32 is closer to the second row 23 and is engaged with the second row 23 more tightly, so that the second row 23 prevents the first row 32 from moving or rotating in the bending moment direction, thereby ensuring that the buckle 3 can still be effectively fixed on the locked element 2 under the action of the external force along the length direction of the installation channel 220 caused by the mistaken collision.

Optionally, the cantilever 310 is rotatably or elastically connected to the body 30. The rotatable connection means that the cantilever 310 and the body 30 are fixed as two structures at the connection 33 and then can rotate around the connection 33, for example, the cantilever 310 can rotate on the plane formed by the x direction and the y direction in fig. 3 or fig. 4 by being hinged or connected through a torsion spring and taking the connection 33 as the center. The elastic connection means that the cantilever 310 and the body 30 are configured as a single structure, and the joint 33 can rotate around the joint 33, for example, the cantilever 310 and the body 30 are integrally formed, and the joint 33 can be elastically deformed, so that the rotation within a certain angle range can be performed.

Alternatively, as shown in fig. 2, 3 and 4, the cantilever 310 may protrude from the side of the body 30. When the cantilever 310 is a structure protruding out of the side of the body 30, the first tooth row 32 is disengaged from the second tooth row 23, and the cantilever 310 is rotated or bent in a direction approaching the other cantilever 310 by only pressing the cantilever 310, so that the first tooth row 32 is disengaged from the second tooth row 23, and the engagement between the first tooth row 32 and the second tooth row 23 is released, thereby releasing the fixation between the buckle 3 and the locked element 2.

Alternatively, the cantilever 310 may be parallel to the side of the body 30. When the cantilever 310 is parallel to the side of the body 30, in the process of clamping the buckle 3, and when the first tooth row 32 and the second tooth row 23 are in the engaged state, the teeth at each position on the first tooth row 32 are uniformly stressed, so that the damage caused by the excessive concentration of stress on part of the teeth can be avoided, and at this time, the fixation between the buckle 3 and the locked piece 2 can be released by pressing the cantilever 310.

Alternatively, the width of the cantilever 310 in the tooth width direction of the first row 32 is greater than the tooth width of the first row 32, and the tooth width of the first row 32 coincides with the tooth width of the second row 23, or the width of the cantilever in the tooth width direction of the first row 32 is equal to the tooth width of the first row 32, and the tooth width of the first row 32 is greater than the tooth width of the second row 23. Illustratively, fig. 5 is an isometric view corresponding to fig. 3 provided by an embodiment of the present application, and fig. 6 is a partially enlarged view of the point K in fig. 5 provided by an embodiment of the present application, and as shown in fig. 5 and fig. 6, the tooth width of the first tooth row 32 on the cantilever 310 is equal to the width of the cantilever 310, and the tooth width of the first tooth row 32 is greater than the tooth width of the second tooth row 23, so that when engaged, a portion of the cantilever 310 is exposed and is in a reachable state, so as to facilitate pressing the cantilever 310 for unlocking.

Further, by providing the pressing blocks on the two cantilever arms 310, when the pressing blocks are pressed, the two cantilever arms 310 can be pulled to rotate or bend in the direction of approaching each other, so that the first tooth row 32 is disengaged from the second tooth row 23, and the engagement between the first tooth row 32 and the second tooth row 23 is released, thereby releasing the fixation between the buckle 3 and the object 2.

Optionally, as shown in fig. 2, 4 and 6, an interaction panel 34 is disposed on a side of the buckle 3 away from the locked component 2, and the interaction panel 34 located between the cantilevers 310 includes a prompt pattern or text to prompt a user to press both sides of the cantilevers 310 to unlock, so as to guide the user to perform correct operation, prevent time waste due to misoperation, and prevent the structure of the buckle 3 from being damaged. Specifically, as shown in fig. 6, a certain gap is formed between the interactive panel 34 and the cantilever 310 of the buckle 3 to avoid that the cantilever 310 touches the interactive panel 34 and the unlocking is not smoothly performed when the cantilever 310 rotates or bends in a direction of approaching each other.

Optionally, the width of the mounting channel 220 is less than or equal to the distance between the cantilever arms 310. When the width of the installation channel 220 is smaller than the distance between the cantilever arms 310, after the cantilever arms 310 are pushed into the installation channel 220, the cantilever arms 310 rotate or bend in the direction of approaching each other under the pressing of the side walls at the two sides of the installation channel 220, and the cantilever arms 310 have the elastic force for restoring the default state, so that after the first row of teeth 32 is meshed with the second row of teeth 23, the cantilever arms 310 have the force for rotating in the direction of separating from the other cantilever arms 310 to restore the natural state before being pushed into the installation channel 220, thereby making the meshing effect of the first row of teeth 32 and the second row of teeth 23 stronger. When the width of the mounting channel 220 is equal to the distance between the cantilevers 310, the resistance of the first tooth row 32 when the clip 3 is pushed into the mounting channel 220 is small, the pushing is easier to complete the engagement, the structure is simpler, the processing is more convenient, and the fixing effect of the clip 3 is effectively ensured.

The buckle 3 provided by the embodiment of the present application can set the installation channel 220 on the locked member 2, when two second tooth rows 23 are respectively located at two sides of the installation channel 220, by setting the cantilever 310 at two sides of the buckle 3, and setting the first tooth row 32 at one side where the cantilever 310 is away from each other, when the first tooth row 32 of the buckle 3 is engaged with the second tooth rows 23 at two sides of the installation channel 220, the movement of the buckle 3 in the length direction and the width direction of the installation channel 220 is limited, and when an external force is applied to the buckle along the length direction of the installation channel 220 away from the box body panel 11 (i.e. along the installation direction), the cantilever 310 generates an outward bending moment, so that the engagement of the first tooth row 32 and the second tooth row 23 is firmer. Through the meshing of first tooth row 32 and second tooth row 23, fix buckle 3 on by latch fitting 2, the restriction buckle is at the removal of two directions, makes buckle 3 can not break away from because of the mistake touches from the anti-direction of installation direction to when casing 22 meets the external force along the installation direction, the meshing effect between buckle and the casing is better, effectively improves box panel 11 and by the fixed effect between latch fitting 2.

As shown in fig. 2 and 4, in some embodiments, a transition section 35 is provided between the cantilever 310 and the body 30, and the cantilever 310 and the body 30 are connected by the transition section 35.

Since the cantilever arms 310 are configured to rotate or bend in a direction approaching the other cantilever arm 310 under an external force, when the clip 3 is pushed into the mounting channel 220 or during the process of releasing the clip 3 from the locked member 2 by pressing the cantilever arms 310, the cantilever arms 310 change the distance between the cantilever arms 310 and the side wall of the mounting channel 220 by rotating or bending, so that the first row of teeth 32 is engaged with the second row of teeth 23, or the first row of teeth 32 is released from the second row of teeth 23. When the cantilever 310 is pressed to separate the first tooth row 32 from the second tooth row 23, the cantilever 310 is rotated or bent due to the external force, and at this time, the stress at the connection position of the cantilever 310 and the body 30 is dispersed through the transition section 35, so that the cantilever 310 is prevented from being broken from the body 30 due to the rotation or bending, and the service life of the buckle 3 is prolonged.

Optionally, the transition section 35 may be configured as an inclined surface or an arc surface, and the force pressing the cantilever 310 may be better dispersed through the inclined surface or the arc surface, so as to prevent the transition section 35 from breaking due to the bearing of more force. Moreover, when the cantilever 310 protrudes out of the side surface of the body 30, the inclined surface or the arc surface can provide a route guide when the clip 3 pushes into the mounting channel 220, so that the pushing obstruction is reduced, and the mounting efficiency of the clip 3 can be further improved and the mounting accuracy of the clip can be further ensured.

As shown in fig. 2 and 4, in some embodiments, the teeth of the first row 32 and the teeth of the second row 23 are helical teeth, the teeth of the first row 32 are inclined from the root to the tip in a direction away from the junction 33, and the junction 33 is the connection location of the cantilever 310 and the body 30.

Illustratively, as shown in fig. 4, the face of the teeth of the first row 32 facing the body 30 is inclined in the opposite direction y from the root to the tip, the contact surface of the teeth of the first row 32 and the contact surface of the teeth of the second row 23 are both inclined surfaces, and the tooth profile shapes and sizes of the teeth of the first row 32 and the teeth of the second row 23 are matched, so that when the teeth of the first row 32 are engaged with the teeth of the second row 23 in the installation direction, the teeth of the first row 32 and the teeth of the second row 23 are mutually restricted and fixed, thereby completing the fixing of the buckle 3 and the locked piece 2.

During installation, the clip 3 is pushed from the end of the housing 22 remote from the front panel 21 to the end close to the front panel 21, i.e. in the direction of installation, which is shown in the y-direction in fig. 3, 4, 5 and 6, so that the teeth of the first row of teeth 32 located on the cantilever 310 gradually contact the teeth of the mounting channel 220 and the second row of teeth 23 on the side wall of the mounting channel 220. Because the tooth root to the tooth top of the teeth of the first row of teeth 32 are inclined in the direction away from the connecting part 33 of the cantilever 310 and the body 30, that is, when the teeth of the first row of teeth 32 are installed, under the action of thrust in the installation direction, the tooth root and the tooth top successively pass through the teeth of the second row of teeth 23 in the installation direction, and the inclined plane formed by the inclination of the tooth root to the tooth top of the teeth of the first row of teeth 32 contacts and passes through the teeth of the second row of teeth 23 and then is automatically engaged with the tooth profile of the second row of teeth 23, the fixation between the first row of teeth 32 and the second row of teeth 23 is completed.

For example, there may be more than one tooth in the first row 32 and more than one tooth in the second row 23. When the buckle 3 is installed, the teeth of the first tooth row 32 can be meshed with the first teeth of the second tooth row 23 in contact to complete fixation, and can also be meshed with the second teeth of the second tooth row 23 in contact to complete fixation, and so on, it is easy to understand that the teeth on the second tooth row 23 are distributed along the installation direction, the closer the teeth on the second tooth row 23 meshed with the teeth of the first tooth row 32 are to the front panel 21, the closer the distance between the buckle 3 and the box panel 11 is, the greater the force of the buckle 3 against the box panel 11 is, the stronger the degree of clamping the box panel 11 by the buckle 3 and the front panel 21 is, and the firmer the buckle 3 is fixed on the box panel 11 by the locking piece 2. Therefore, when the number of teeth of the first tooth row 32 and the second tooth row 23 is plural, the strength of the buckle 3 against the box body panel 11 can be flexibly adjusted when mounting, so that the firmness of being fixed on the box body panel 11 by the locking piece 2 can be flexibly adjusted.

Optionally, the number of teeth of the first row of teeth 32 is less than or equal to the number of teeth of the second row of teeth 23. It can be understood that the size of the clip 3 as a component for fixing the locked member 2 and the case panel 11 is generally smaller than that of the locked member 2, that is, the size of the clip 3 is smaller than that of the housing 22 of the locked member 2, so that the number of teeth of the first tooth row 32 is smaller, thereby ensuring that the size of the clip 3 is smaller and avoiding occupying more space. In addition, buckle 3 is as the spare part that needs move on the installation direction at first tooth row 32 place when the installation, sets up the number of teeth of first tooth row 32 for being less than or equal to the number of teeth of second tooth row 23, is favorable to first tooth row 32 to select the tooth of second tooth row 23 on the installation direction with it engaged with to adjust the intensity that buckle 3 supported box panel 11 in a flexible way.

The buckle 3 that this application embodiment provided, set up to the direction slope of keeping away from cantilever 310 and body 30 junction 33 from the tooth root to the addendum through the tooth with first tooth row 32, can only need exert the ascending power of an installation direction to buckle 3 when the installation, buckle 3 alright by between the second tooth row 23 by latch fitting 2 by impelling, automatic meshing is fixed mutually between first tooth row 32 and the second tooth row 23, in order to accomplish buckle 3 and by the fixed between latch fitting 2, prevent in the propulsion process, the dead condition of mutual card between the tooth of first tooth row 32 and the tooth of second tooth row 23, buckle 3's installation has been made things convenient for.

On the basis of the above-mentioned embodiments, considering that the cantilever 310 has a greater or lesser degree of rotation or bending during installation and unlocking, in order to ensure the service life of the buckle 3, further limitation needs to be made on the degree of rotation or bending of the cantilever 310 to prevent the cantilever 310 from breaking due to over-rotation or bending.

For example, fig. 7 is a schematic structural diagram of a buckle 3 with a limiting rib 301 according to an embodiment of the present disclosure, as shown in fig. 7, when two cantilevers 310 are pressed to approach each other, if the distance between the two cantilevers 310 is relatively long and there is no structure capable of limiting the rotation angle of the two cantilevers 310, the cantilevers 310 may break when the cantilever 310 is forced too much due to poor control of the pressing force. In order to prevent the cantilever 310 from being excessively bent or rotated by an excessive external force pressing the cantilever 310 when unlocking, and thus causing the cantilever 310 to be excessively bent or rotated to break, optionally, as shown in fig. 7, in a possible implementation manner, the body 30 includes a limiting rib 301, and the limiting rib 301 is disposed between two cantilevers 310 to limit the rotation or bending degree of the cantilevers 310.

Optionally, fig. 8 is a schematic structural diagram of the buckle 3 corresponding to fig. 7 when unlocking, as shown in fig. 8, the limiting rib 301 may be a segment of limiting structure extending from the body 30 in a direction opposite to the mounting direction, a bottom of the limiting rib 301 may be flush with a bottom of the cantilever 310, and the bottom of the cantilever 310 refers to an end of the cantilever 310 not connected to the body 30, that is, a free end of the cantilever 310. The cantilever 310 in fig. 7 is pressed to make the position of the cantilever 310 as shown in fig. 8, when the cantilever 310 is pressed to rotate, the change of the arc length passed by the bottom of the cantilever 310 is the largest, when the force pressing the cantilever 310 is larger, the bottom of the cantilever 310 can be changed greatly in the first time, therefore, the limiting rib 301 extends to the bottom of the cantilever 310, the further rotation or bending of the cantilever 310 can be prevented in the first time, and the breakage of the cantilever 310 caused by over-rotation or bending can be effectively prevented.

Fig. 9 is a schematic structural diagram of another limiting rib 301 of the buckle 3 provided in the embodiment of the present application, as shown in fig. 9, the limiting rib 301 may be disposed to protrude from the interactive panel 34 toward one surface of the housing 22, and the limiting rib 301 does not need to extend from one end of the interactive panel 34 to the other end, but may be disposed only at a position corresponding to the free end of the cantilever 310, so that when the cantilevers 310 rotate toward a direction approaching each other, the bottom of the cantilever 310 may contact the limiting rib 301 after rotating to a certain extent, so as to effectively prevent the cantilevers 310 from being broken due to over-rotation or bending, and since the length of the limiting rib 301 is shorter, the material of the buckle 3 is saved and the weight of the buckle 3 is reduced.

For example, as shown in fig. 9, the projection of the cantilever 310 and the projection of the limiting rib 301 at least partially coincide along the width direction of the mounting channel 220 (e.g., the x direction in fig. 1 to 9), so as to ensure that the limiting rib 301 is located on the rotation path of the cantilever 310 when the cantilever 310 is pressed to rotate towards the other cantilever 310, so as to effectively prevent the cantilever 310 from over-rotating or bending, and prevent the cantilever 310 from breaking due to over-rotating or bending.

Furthermore, optionally, the protruding height of the limiting rib 301 from the back surface of the interactive panel 34 in the depth direction (e.g., z direction in fig. 1 to 9) of the mounting channel 220 is not necessarily greater than or equal to the distance between the side of the cantilever 310 away from the interactive panel 34 and the back surface of the interactive panel, as long as the limiting rib can at least partially contact with the cantilever 310 during the rotation or bending of the cantilever 310, thereby further saving material and preventing the cantilever 310 from excessively rotating or bending.

This application embodiment is through setting up spacing muscle 301 between two cantilevers 310 to after two cantilevers 310 are pressed to a certain extent in opposite directions, make two cantilevers 310 support on spacing muscle 301, spacing muscle 301 can in time prevent cantilever 310 further rotation or crooked, thereby avoid the fracture that causes because of the great messenger cantilever 310 excessive rotation of the power of pressing cantilever 310 or crooked, improve buckle 3's life.

Alternatively, fig. 10 is a schematic structural diagram of one protrusion 302 provided in an embodiment of the present application, and fig. 11 is a schematic structural diagram of another protrusion 302 provided in an embodiment of the present application, as shown in fig. 10 and fig. 11, in another possible implementation manner, the protrusions 302 are disposed on sides of the cantilevers 310 close to each other to limit the degree of rotation or bending of the cantilevers 310.

For example, in order to prevent the cantilever 310 from being excessively bent or broken due to an excessively large external force pressing the cantilever 310 during unlocking, the protrusion 302 may be disposed on a side where the cantilevers 310 approach each other, so that the cantilever 310 is prevented from being excessively rotated or bent in a direction approaching another cantilever 310 during the process of pressing the cantilever 310 to separate the first tooth row 32 from the second tooth row 23, thereby preventing the cantilever 310 from being excessively rotated or bent and prolonging the service life of the buckle 3.

Alternatively, the protrusion 302 may be a round or square bump, or may also be an oval or rectangular rib, which is not limited in this application.

Alternatively, as shown in fig. 10, the protrusions 302 may be disposed on the sides of the free ends of the cantilever 310 that are close to each other, or, as shown in fig. 11, the protrusions 302 may be disposed on the sides of the middle portions of the cantilever 310 that are close to each other, to prevent further rotation or bending of the cantilever 310 at a first time.

Alternatively, there may be a plurality of protrusions 302, and the plurality of protrusions 302 are distributed on the side where the cantilever 310 is close to each other along the installation direction, so that when the protrusion 302 close to the root of the cantilever 310 is worn, the second protrusion 302 close to the root of the cantilever 310 takes on the limiting function, and the life of the limiting function of the buckle 3 is prolonged.

Alternatively, the protrusions 302 may be disposed on only one side of one of the cantilever arms 310 adjacent to the other cantilever arm 310, or may be disposed on each side of the two cantilever arms 310 adjacent to each other.

The buckle 3 that this application embodiment provided sets up protruding 302 through the one side that is close to each other at two cantilevers 310, after two cantilevers 310 were pressed to certain degree in opposite directions, protruding 302 on two cantilevers 310 can contact to in time prevent cantilever 310 further rotation or crooked, avoid the fracture that causes because of pressing cantilever 310's the great messenger cantilever 310 excessive rotation of power or bending, improve buckle 3's life.

It will be appreciated that the above-described solutions of the position-limiting ribs 301 and the protrusions 302 can be flexibly combined. For example, the stopper rib 301 may be provided only between the cantilever arms 310, the protrusion 302 may be provided only on the side where the cantilever arms 310 are close to each other, or the stopper rib 301 may be provided between the cantilever arms 310 and the protrusion 302 may be provided on the side where the cantilever arms 310 are close to each other.

Considering that clip 3 is fixed to locked member 2 by first tooth row 32, one end of clip 3 close to case panel 11 in the mounting direction can be made to abut tightly against case panel 11 to clamp case panel 11 between clip 3 and front panel 21 of locked member 2, thereby fixing locked member 2 to case panel 11 by clip 3. Therefore, the end of the buckle 3 away from the cantilever 310 is usually configured to have a deformation structure with a certain elasticity, so that the box body panel 11 can be tightly pressed by the elasticity of the deformation structure when the buckle 3 is fixed on the locked member 2.

However, the buckle 3 and the locked object 2 are fixed by the engagement of the first tooth row 32 and the second tooth row 23, and the distance unit of the first tooth row 32 approaching the case panel 11 is the tooth root width of the teeth, so that when the buckle 3 is used for adjusting the engagement of the first tooth row 32 and the second tooth row 23, only the gradient can be changed to the degree that the buckle 3 abuts against the case panel 11, the situation of over-tightness or over-looseness easily exists, and the deformation structure cannot be guaranteed to abut against the case panel 11 certainly. Although the size is designed, and under the conditions of high processing precision and processing size standard, the deformation structure can just meet the requirement of abutting against the box body panel 11, the requirement on processing is too high, the size is easily changed due to abrasion caused by a plurality of using times, and the clamping effect is reduced. Moreover, the machining size needs to be correspondingly modified according to different locked parts 2, and the buckle 3 which is suitable for the locked parts 2 with the size is produced after modification, so that the use flexibility and the use rate of the buckle 3 are greatly weakened, the buckle is not suitable for batch production, and the low-cost principle of parts of the buckle 3 is violated.

Accordingly, in view of the above considerations, as shown in fig. 2, 3, 5, 7, 8, 9, 10 and 11, in some embodiments, the clip 3 further includes a bracket 36, and the bracket 36 is fixedly connected to an end of the body 30 away from the cantilever 310 and extends in a direction away from the body 30. The supporting frame 36 includes two frame bodies 361, an included angle is formed between the two frame bodies 361, and any one frame body 361 can rotate or bend in a direction away from the other frame body 361 under an external force.

Alternatively, the bracket 36 may be integrally formed with the body 30, or the bracket 36 may be rotatably or elastically coupled to the body 30, and the bracket 36 may rotate with a position where the bracket 36 is coupled to the body 30 as a rotation center. Specifically, the initial positions of the two frame bodies 361 are relatively close to each other, the included angle between the two frame bodies 361 is greater than 0 degree and smaller than 180 degrees, and the two frame bodies 361 are respectively located on two sides of the installation direction. The frame body 361 and the body 30 are connected in a rotating mode or in an elastic mode, and the force for restoring the initial position of the frame body 361 can be given to the frame body 361, so that the frame body 361 can abut against the box body panel 11 due to the force for restoring the initial position when the buckle 3 moves towards the box body panel 11, the front panel 21 of the locked piece 2 is matched with the frame body panel 11, the box body panel 11 is clamped together, and the locked piece 2 is firmly fixed on the box body panel 11.

The buckle 3 that the embodiment of the application provided, through the one end setting that keeps away from cantilever 310 at body 30 have two support 36 of support body 361, can be when buckle 3 is promoted to be close to box panel 11, two support bodies 361 at first contact box panel 11, and support box panel 11, two support bodies 361 take place to rotate respectively or crooked and keep away from each other under the thrust effect that lasts, after getting rid of thrust, two support bodies 361 have the trend of restoring initial angle under self elastic action, thereby tightly support and lean on box panel 11, and exert the effort to box panel 11, thereby press from both sides box panel 11 together with front panel 21 by locking piece 2, will firmly be fixed on box panel 11 by locking piece 2.

On the basis of the above-mentioned embodiment, considering that the two holders 361 are rotated or bent to a greater or lesser extent when in use, in order to ensure the service life of the buckle 3, the rotation or bending degree of the holders 361 needs to be further limited to prevent the holders 361 from being broken due to over-rotation or bending. Therefore, as shown in fig. 2, 3, 5, 7, 8, 9, 10 and 11, in some embodiments, a position-limiting pillar 362 protruding from the body 30 is disposed between the two frame bodies 361 for limiting the position of the clip 3.

As shown in fig. 2, 3, 5, 7, 8, 9, 10 and 11, the limiting post 362 protrudes from the surface of the body 30 where the bracket 36 is disposed, when the buckle 3 is pushed in the installation direction, the two frame bodies 361 gradually rotate or bend in a direction away from the other frame body 361, and the limiting post 362 protrudes from the body 30 and can contact the box body panel 11 before the two frame bodies 361 excessively rotate or bend, so as to timely prevent the buckle 3 from being pushed continuously in the installation direction, and prevent the two frame bodies 361 from fatigue due to excessive deformation or fracture due to excessive rotation or bending.

As shown in fig. 2, 7, 8, 9, 10 and 11, in some embodiments, the buckle 3 further includes a slide rail 37, the slide rail 37 is connected to the body 30, and when the two cantilevers 310 are disposed at an included angle, the slide rail 37 is parallel to a bisector of the two cantilevers 310, or when the two cantilevers 310 are parallel to each other, the slide rail 37 is parallel to the two cantilevers 310.

It can be understood that the cantilever 310 is elastically or rotatably connected to the body 30, so that the angle between the cantilevers 310 is different before, during and after use, but the bisector of the angle between the two cantilevers 310 is always in the installation direction of the buckle 3 no matter how the angle of the cantilever 310 changes. The slide rail 37 is used as a structure for guiding the installation of the buckle 3, and the installation process of the buckle 3 is not affected by the angle change of the cantilever 310, so that the slide rail 37 is arranged on the body 30 of the buckle 3, and the slide rail 37 is parallel to the installation direction, and the slide rail 37 can be effectively used for guiding the installation.

Alternatively, fig. 12 is a schematic structural diagram of a slide rail 37 provided in an embodiment of the present application, as shown in fig. 12, the slide rail 37 may be disposed on a side of the body 30 close to the housing 22, the slide rail 37 is T-shaped, the housing 22 of the locked component 2 is provided with a rail matching with the size and shape of the slide rail 37, the slide rail 37 is disposed in the rail and can slide in the rail to guide the installation of the buckle 3, and the T-shaped slide rail 37 and the rail can enable the rail to limit the movement of the slide rail 37 in a direction perpendicular to the housing 22 (e.g., a z direction in fig. 12), so as to further fix the buckle 3 on the housing 22 of the locked component 2.

The buckle 3 that this application embodiment provided guides buckle 3's installation through slide rail 37, and buckle 3 is moving along slide rail 37 and the in-process of installing, and the moment of flexure of two cantilevers 310 is the same basically, prevents the easy cracked risk of arbitrary cantilever 310, has promoted buckle 3's life, and makes buckle 3's installation convenient and fast more through slide rail 37's guide effect.

Fig. 13 is a schematic structural view of another sliding rail 37 provided in an embodiment of the present application, as shown in fig. 7, 12 and 13, in some embodiments, the sliding rail 37 is disposed on two sides of the body 30 and protrudes out of a side surface of the body 30, and a distance d between the sliding rails 37₁Is less than or equal to the farthest distance d between the sides of the cantilevers 310 away from each other₂。

Illustratively, two sliding rails 37 are distributed on two sides of the body 30 and protrude from the side surfaces of the body 30. The housing 22 of the locked member 2 is provided with grooves matching the size and shape of the slide rails 37, the grooves are distributed on both sides of the installation channel 220 and are recessed to the sides away from each other. The slide rail 37 is placed in the groove and slides in the groove in the mounting direction, thereby guiding the mounting of the buckle 3. In addition, the engagement of the groove and the sliding rail 37 can make the sliding rail 37 be limited to move in a direction perpendicular to the first outer wall 221 of the housing 22 of the locked member 2, i.e., in a depth direction (e.g., z direction in fig. 13) of the installation channel 220, further fixing the buckle 3 on the housing 22 of the locked member 2.

Alternatively, the buckle 3 is regarded as two parts from the connection 33 of the body 30 and the cantilever 310, and the slide rail 37 is provided at a portion excluding the cantilever 310. When the body 30 and the cantilever 310 pass through the same mounting channel 220 one after another, since the distance between the sliding rails 37 is less than or equal to the farthest distance between the sides of the cantilever 310 away from each other, the body 30 and the sliding rails 37 do not interfere with the second rack row 23 and pass through smoothly, but the second rack row 23 can press the cantilever 310 to bend the cantilever 310 and finally engage the first rack row 32 with the second rack row 23, so that the above arrangement of the sliding rails 37 can prevent the sliding rails 37 from interfering with the engagement of the first rack row 32 with the second rack row 23.

The buckle 3 that this application embodiment provided, through setting up the slide rail 37 of protrusion in the side of body 30, can be in the installation of guide buckle 3, restriction buckle 3's removal on the direction of depth of installation passageway 220 avoids bumping because of the mistake and breaks away from to consolidate buckle 3 and by the fixed between locking piece 2. And, by setting the distance d between the slide rails 37₁So that it is less than or equal to the farthest distance d between the sides of the cantilevers 310 away from each other₂The slide rail 37 can be effectively prevented from damaging the second rack 23.

The cabinet panel 11 is provided with a mounting hole 110.

Buckle 3 is located in installation passageway 220, and first tooth row 32 and the cooperation of second tooth row 23 of buckle 3 are in order to fix buckle 3 on casing 22, and the body 30 of buckle 3 supports on box panel 11 to be fixed on box panel 11 by lock 2.

Specifically, the included angle is greater than 0 degree between the first outer wall 221 of the housing 22 and the front panel 21, for example, a fixed included angle of 90 degrees is formed between the first outer wall 221 and the front panel 21.

Alternatively, the catches 3 may be provided on the respective two sides of the housing 22 of the locked member 2 to restrict the movement of the locked member 2 from the respective two directions, enhancing the fixing effect of the catches 3 to be fixed by the locked member 2 on the box body panel 11 of the electric box 1.

Optionally, the housing 22 is provided with a mounting channel 220 parallel to the mounting direction, and the body 30 and the cantilever 310 of the buckle 3 pass through the mounting channel 220 in the mounting direction. Both sides of mounting channel 220 are provided with second row of teeth 23, and when clip 3 passes through mounting channel 220, second row of teeth 23 engages with first row of teeth 32 of cantilever 310 to fix clip 3 to locked element 2.
