The self-locking railway switch adjustment sheet 100 provided by the embodiment can be quickly installed and has a self-locking function.

The self-locking railway switch adjustment sheet 100 provided by this embodiment includes a sheet body 110, a first elastic sheet 130 and a second elastic sheet 150, a notch 111 for clamping a bolt is provided at the outer edge of the sheet body 110, and according to practical application conditions, an expansion opening can be additionally provided at the opening position of the notch 111 to facilitate the clamping of the bolt. The relative both sides of breach 111 are provided with first breach wall 1111 and second breach wall 1113 respectively, first mounting groove 113 has been seted up on first breach wall 1111, second mounting groove 115 has been seted up on second breach wall 1113, first shell fragment 130 sets up in first mounting groove 113 and stretches into in breach 111, second shell fragment 150 sets up and stretches into in breach 111 equally in second mounting groove 115, first shell fragment 130 is used for taking place deformation in the in-process of bolt card income breach 111 and supply the bolt to block the bolt and go into completely the breach, and be used for blockking the bolt and withdraw from the breach, realize the locking to the bolt.

The first mounting groove 113 communicates one end of the notch 111 to one end far away from the notch 111, and the first mounting groove gradually approaches the opening position of the notch 111 in the extending direction parallel to the notch 111, as shown in fig. 1, the notch 111 extends vertically upward. The first and second sidewalls 1131 and 1133 are respectively disposed on two opposite sides of the first mounting groove 113, and the second sidewall 1133 is closer to the opening of the notch 111 than the first sidewall 1131, that is, the second sidewall 1133 is located below the first sidewall 1131.

The first elastic sheet 130 is provided with a first connecting end 131 and a first movable end 133, the first connecting end 131 is connected with the bottom wall of the first installation groove 113, the first movable end 133 extends into the notch 111 along the first installation groove 113, that is, in a direction parallel to the extending direction of the notch 111, the distance between the first movable end 133 and the opening position of the notch 111 is greater than the distance between the first connecting end 131 and the opening position of the notch 111.

Gaps are formed between the first elastic sheet 130 and the first side wall 1131 and between the first elastic sheet 130 and the second side wall 1133, when the first movable end 133 rotates to contact with the first side wall 1131 under the action of the bolt, the distance between the first movable end 133 and the second gap wall 1113 is greater than the distance between the first movable end 133 and the second gap wall 1113 when the first movable end 133 rotates to contact with the second side wall 1133, and when the first movable end 133 contacts with the second side wall 1133, the first movable end 133 keeps extending into the gap 111.

In this embodiment, in order to ensure that the first elastic sheet 130 can deform enough under the pushing of the bolt, in practical applications, the gap between the first elastic sheet 130 and the first side wall 1131 should be adaptively set according to the diameter of the clamped bolt, so as to ensure that the target bolt can be smoothly and completely clamped into the notch 111. In addition, to prevent excessive deformation of the push spring when the bolt has a tendency to exit the notch 111, the size of the gap between the first spring 130 and the second sidewall 1133 is set to be sufficiently small. That is, in the plane of blade 110, the size of the opening between first side wall 1131 and first movable end 133 is greater than the size of the opening between second side wall 1133 and first movable end 133.

Furthermore, in this embodiment, the first sidewall 1131 includes a first branch 1132 and a second branch 1134, one end of the first branch 1132 is connected to the bottom of the first mounting groove 113, the other end of the first branch 1132 is connected to the second branch at an included angle 1134, one end of the second branch 1134 far from the first branch 1132 extends to the first notch wall 1111, the included angle between the second branch 1134 and the first elastic piece 130 is greater than the included angle between the first branch 1132 and the first elastic piece 130, and the second branch 1134 is gradually far away from the first elastic piece 130 from the end connected to the first branch 1132.

It can be understood that a convex point facing the first resilient tab 130 is formed at the connection position of the first branch section 1132 and the second branch section 1134, and in the process of clamping the bolt into the notch 111, when the first resilient tab 130 is subjected to the acting force of the bolt, the first resilient tab 130 firstly rotates with the first connection end 131 as a rotation fulcrum, and after a small rotation stroke, the first resilient tab 130 contacts with the convex point formed at the connection position of the first branch section 1132 and the second branch section 1134. Then, under the action of the subsequent force of the bolt, the first elastic sheet 130 rotates with the position contacting with the salient point as a rotation fulcrum. Because the second branch section 1134 is away from the first elastic sheet 130 gradually from the end connected with the first branch section 1132 to the end far away from the first branch section 1132, the first elastic sheet 130 can deform to a greater extent under the subsequent acting force of the bolt, so that the bolt can be smoothly clamped in.

In addition, in order to further ensure that the bolt can be smoothly clamped into the notch 111, in the embodiment, the opening between the first side wall 1131 and the first movable end 133 faces a direction away from the opening position of the notch 111, and the opening between the second side wall 1133 and the first movable end 133 faces a direction close to the opening position of the notch 111.

Referring to fig. 1 and 2, the first movable end 133 is provided with a first contact surface 1331, a first acting surface 1332, a first release surface 1333, a first guiding surface 1335 and a second contact surface 1337, the first contact surface 1331 is disposed corresponding to the first sidewall 1131, the second contact surface 1337 is disposed corresponding to the second sidewall 1133, one end of the first acting surface 1332 is connected to the first contact surface 1331, the other end of the first acting surface 1332 is connected to one end of the first release surface 1333, the other end of the first release surface 1333 is connected to one end of the first guiding surface 1335, the other end of the first guiding surface 1335 is connected to the second contact surface 1337, and an included angle exists between the first acting surface 1332 and the first guiding surface 1335.

To further ensure that the bolt can be smoothly inserted into the notch 111, the first guiding surface 1335 gradually approaches the position of the central line of the notch 111 from the end connected with the second contact surface 1337 to the end connected with the first disengaging surface 1333 of the first guiding surface 1335. That is, the first guiding sliding surface 1335 gradually shrinks from the opening position close to the notch 111 to the end of the opening position far away from the notch 111, so as to guide the bolt. Furthermore, the first acting surface 1332 and the first guiding surface 1335 are smoothly transited to prevent the bolt from being stuck when passing over the first elastic sheet 130.

In this embodiment, the second mounting groove 115 and the first mounting groove 113 are symmetrically disposed about the center line direction of the notch 111, and the second resilient tab 150 and the first resilient tab 130 are symmetrically disposed about the center line direction of the notch 111. That is, in the process of fastening the notch 111 into the bolt, the first elastic piece 130 and the second elastic piece 150 deform simultaneously, and when sufficient deformation occurs, the bolt passes over the first elastic piece 130 and the second elastic piece 150 simultaneously, and the first elastic piece 130 and the second elastic piece 150 elastically reset simultaneously.

The second mounting groove 115 communicates one end of the notch 111 to one end far from the notch 111, and is gradually close to the opening position of the notch 111 in the extending direction parallel to the notch 111. Opposite sides of the second mounting groove 115 are respectively provided with a third side wall 1151 and a fourth side wall 1153, the third side wall 1151 is closer to the opening position of the notch 111 than the fourth side wall 1153, that is, the fourth side wall 1153 is located below the third side wall 1151.

The second elastic sheet 150 is provided with a second connection end 151 and a second movable end 153, the second connection end 151 is connected with the bottom wall of the second installation groove 115, the second movable end 153 extends into the notch 111 along the second installation groove 115, that is, in a direction parallel to the extending direction of the notch 111, the distance between the second movable end 153 and the opening position of the notch 111 is greater than the distance between the second connection end 151 and the opening position of the notch 111.

A gap is formed between the second elastic piece 150 and each of the third side wall 1151 and the fourth side wall 1153, when the second movable end 153 rotates to contact with the third side wall 1151 under the action of the bolt, the distance between the second movable end 153 and the first notch wall 1111 is greater than the distance between the second movable end 153 and the first notch wall 1111 when the second movable end 153 rotates to contact with the fourth side wall 1153, and when the second movable end 153 contacts with the fourth side wall 1153, the second movable end 153 keeps extending into the notch 111.

In this embodiment, in order to ensure that the second elastic sheet 150 can deform sufficiently under the pushing of the bolt, in practical applications, the gap between the second elastic sheet 150 and the third side wall 1151 should be adaptively set according to the diameter of the clamped bolt, so as to ensure that the target bolt can be smoothly and completely clamped into the notch 111. In addition, to prevent excessive deformation of the push spring when the bolt has a tendency to exit the notch 111, the gap between the second spring 150 and the fourth side wall 1153 is sized to be sufficiently small. I.e., in the plane of the blade 110, the opening between the third side wall 1151 and the second movable end 153 is larger than the opening between the fourth side wall 1153 and the second movable end 153.

In addition, in this embodiment, the third side wall 1151 includes a third branch segment 1152 and a fourth branch segment 1154, one end of the third branch segment 1152 is connected to the bottom of the second mounting groove 115, the other end of the third branch segment 1152 is connected to the second branch segment at an included angle 1134, one end of the fourth branch segment 1154, which is far away from the third branch segment 1152, extends to the second notch wall 1113, the included angle between the fourth branch segment 1154 and the second elastic sheet 150 is greater than the included angle between the third branch segment 1152 and the second elastic sheet 150, and the fourth branch segment 1154 is gradually far away from the second elastic sheet 150 from the end connected to the third branch segment 1152.

It can be understood that a protruding point facing the second elastic sheet 150 is formed at the connection position of the third branch section 1152 and the fourth branch section 1154, when the second elastic sheet 150 is acted by the bolt in the process of clamping the bolt into the notch 111, the second elastic sheet 150 firstly rotates with the second connection end 151 as a rotation fulcrum, and after a small rotation stroke, the second elastic sheet 150 contacts the protruding point formed at the connection position of the third branch section 1152 and the fourth branch section 1154. Then, under the action of the subsequent force of the bolt, the second elastic sheet 150 rotates with the position contacting with the salient point as a rotation fulcrum. Because the fourth branch segment 1154 is gradually far away from the second elastic sheet 150 from the end connected with the third branch segment 1152 to the end far away from the third branch segment 1152, the second elastic sheet 150 can deform to a greater extent under the subsequent acting force of the bolt, and the bolt can be smoothly clamped.

In addition, in order to further ensure that the bolt can be smoothly clamped into the notch 111, in the embodiment, the opening between the third side wall 1151 and the second movable end 153 faces a direction away from the opening position of the notch 111, and the opening between the fourth side wall 1153 and the second movable end 153 faces a direction close to the opening position of the notch 111.

Referring to fig. 1 and 3, the second movable end 153 is provided with a third contact surface 1531, a second action surface 1532, a second release surface 1533, a second sliding guide surface 1535 and a fourth contact surface 1537, the third contact surface 1531 is disposed corresponding to the third side wall 1151, the fourth contact surface 1537 is disposed corresponding to the fourth side wall 1153, one end of the second action surface 1532 is connected to the third contact surface 1531, the other end of the second action surface 1532 is connected to one end of the second release surface 1533, the other end of the second release surface 1533 is connected to one end of the second sliding guide surface 1535, the other end of the second sliding guide surface 1535 is connected to the fourth contact surface 1537, and an included angle exists between the second action surface 1532 and the second sliding guide surface 1535.

Similarly, the second guiding-sliding surface 1535 gradually approaches the position of the central line of the notch 111 from the end connected to the fourth contacting surface 1537 to the end connected to the second disengaging surface 1533 of the second guiding-sliding surface 1535. That is, the second sliding guide surface 1535 gradually shrinks from the opening position close to the notch 111 to the end far away from the opening position of the notch 111, so as to guide the bolt. Furthermore, the second disengaging surface 1533 and the second sliding guide surface 1535 are smoothly transitioned to prevent the bolt from being stuck when passing over the spring plate.

In the installation process of the self-locking railroad switch adjustment sheet 100 provided in this embodiment, since the distance between the first separation surface 1333 and the second separation surface 1533 is smaller than the diameter of the bolt, the first guiding surface 1335 and the second guiding surface 1535 contact with the bolt first, the first elastic sheet 130 and the second elastic sheet 150 deform in the direction away from the opening of the notch 111, the distance between the first movable end 133 and the second movable end 153 gradually increases until the first separation surface 1333 and the second separation surface 1533 contact with the bolt, and the first separation surface 1333 and the second separation surface 1533 separate from the bolt, and the bolt falls into the bottom of the notch 111, at this time, the first elastic sheet 130 and the second elastic sheet 150 return to the initial state, and the distance between the first separation surface 1333 and the second separation surface 1533 is always smaller than the diameter of the bolt.

When the self-locking railroad switch adjustment sheet 100 is to be detached from the bolt, the first action surface 1332 and the second action surface 1532 are respectively contacted with the cylindrical surface of the bolt, and due to the slope design of the first action surface 1332 and the second action surface 1532, after contacting with the bolt, a first action force and a second action force are respectively generated, the action force 1 is more deviated to the opening direction of the notch 111 along the length direction of the first elastic sheet 130 or more than the direction, and the second action force is more deviated to the opening direction of the notch 111 along the length direction of the second elastic sheet 150 or more than the direction. The first acting force on the first elastic sheet 130 can be decomposed into a first component force towards the notch 111 and the extension direction thereof and a second component force perpendicular to the component force and facing away from the center line of the notch 111, that is, the second component force is in the horizontal direction, but due to the slope design of the first acting surface 1332, in any case, the first component force is always smaller than the second component force, so that it is ensured that the first movable end 133 of the first elastic sheet 130 moves towards the second contact surface 1337 after the first movable end 133 of the first elastic sheet 130 contacts with the bolt, and the self-locking failure caused by the movement towards the first contact surface 1331 direction is avoided.

In this embodiment, the first elastic sheet 130, the second elastic sheet 150 and the sheet body 110 are in the same plane, and the first elastic sheet 130, the second elastic sheet 150 and the sheet body 110 are integrally formed, in other embodiments, the first elastic sheet 130 and the second elastic sheet 150 may be connected to the sheet body 110 by welding.

It is understood that, in other embodiments, the angles of the first mounting groove 113 and the second mounting groove 115 relative to the extending direction of the notch 111 may also be adjusted adaptively, and the extending directions of the first elastic piece 130 and the second elastic piece 150 may be adjusted correspondingly. For example, in another embodiment, the distance between the end of each of the first mounting groove 113 and the second mounting groove 115, which is communicated with the notch 111, and the end of each of the first mounting groove 113 and the second mounting groove 115, which is far away from the notch 111, and the opening position of the notch 111 is equal in the extending direction parallel to the notch 111, that is, the first elastic piece 130 and the second elastic piece 150 both extend in the horizontal direction, in this case, it is sufficient to ensure that the gap between the first side wall 1131 and the first elastic piece 130 is greater than the gap between the second side wall 1133 and the first elastic piece 130, and ensure that the gap between the third side wall 1151 and the second elastic piece 150 is greater than the gap between the fourth side wall 1153 and the second elastic piece 150. In another embodiment, the first mounting groove 113 and the second mounting groove 115 respectively communicate with one end of the notch 111 to one end of the notch 111, which is far away from the opening of the notch 111, in a direction parallel to the extending direction of the notch 111. In this case, it is also ensured that the gap between the first sidewall 1131 and the first elastic sheet 130 is much larger than the gap between the second sidewall 1133 and the first elastic sheet 130, and the gap between the third sidewall 1151 and the second elastic sheet 150 is much larger than the gap between the fourth sidewall 1153 and the second elastic sheet 150.

In practical applications, in the process that the bolt is gradually inserted into the notch 111, the bolt simultaneously pushes the first elastic sheet 130 and the second elastic sheet 150 upward, the first movable end 133 of the first elastic sheet 130 gradually approaches the first side wall 1131 to rotate, the second movable end 153 of the second elastic sheet 150 gradually approaches the third side wall 1151 to rotate, the distance between the first movable end 133 and the second movable end 153 gradually increases, when the distance between the first movable end 133 and the second movable end 153 increases to just exceed the diameter of the target bolt, the bolt successfully passes over the first elastic sheet 130 and the second elastic sheet 150, and the first elastic sheet 130 and the second elastic sheet 150 elastically reset or partially reset due to plastic deformation, thereby completing the clamping of the bolt. When the bolt has a tendency to disengage from the notch 111, the first elastic sheet 130 and the second elastic sheet 150 are pushed downward, the acting force on the first elastic sheet 130 can be decomposed into a first component force towards the notch 111 and the extension direction thereof and a second component force perpendicular to the component force and facing away from the central line of the notch 111, that is, the second component force is in the horizontal direction, but due to the slope design of the first acting surface 1332, in any case, the first component force is always smaller than the second component force, so that the first movable end 133 of the first elastic sheet 130 is ensured to move towards the second contact surface 1337 after the first movable end 133 of the first elastic sheet 130 contacts the bolt, and the self-locking failure caused by the movement towards the first contact surface 1331 direction is avoided. The first movable end 133 rotates close to the second side wall 1133, the second movable end 153 rotates close to the fourth side wall 1153, the distance between the first movable end 133 and the second movable end 153 is gradually reduced until the first movable end 133 abuts against the second side wall 1133, the second movable end 153 abuts against the fourth side wall 1153, at this time, the diameter of the bolt is larger than the distance between the first movable end 133 and the second movable end 153, the first elastic sheet 130 and the second elastic sheet 150 jointly block the bolt, and the bolt cannot slide into the notch 111 along the road. If only the first resilient piece 130 or only the second resilient piece 150 is provided, the resilient piece and the opposite wall of the gap can be acted together to prevent the bolt from sliding out of the gap 111 only by one resilient piece according to the above principle.

In conclusion, the self-locking railway turnout adjustment sheet 100 provided by the embodiment has the advantages that the bolt is clamped through the notch 111, the quick installation is realized, the labor cost is saved, and the self-locking railway turnout adjustment sheet also has the self-locking function and is prevented from falling off.

When the bolt has a tendency to disengage from the notch 111, the first elastic sheet 130 and the second elastic sheet 150 are pushed downward, the acting force on the first elastic sheet 130 can be decomposed into a first component force towards the notch 111 and the extension direction thereof and a second component force perpendicular to the component force and facing away from the central line of the notch 111, that is, the second component force is in the horizontal direction, but due to the slope design of the first acting surface 1332, in any case, the first component force is always smaller than the second component force, so that the first movable end 133 of the first elastic sheet 130 is ensured to move towards the second contact surface 1337 after the first movable end 133 of the first elastic sheet 130 contacts the bolt, and the self-locking failure caused by the movement towards the first contact surface 1331 direction is avoided.
