The following will describe the implementation of the embodiments of the present invention in detail with reference to the drawings and examples, so that the implementation process of the embodiments of the present invention that apply technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented, and the following description will further describe the structure of the present invention with reference to the drawings.
Example 1:
Fig. 1 is a schematic plan view of a clamping device according to an embodiment of the present invention, as shown in fig. 1.
The embodiment of the invention provides a clamping device, which comprises: main sled 10, top sled 20, at least one pair of cleats 30, scissor jack 40, and locking mechanism 50.
Wherein the top sled 20 is movably coupled to the main sled 10. The pair of clamping plates 30 are movably coupled to the main sliding plate 10, and the pair of clamping plates 30 and the top sliding plate 20 form a receiving space. The two ends of the scissors telescopic frame 40 are respectively and rotatably connected with the paired clamping plates 30, and the scissors telescopic frame 40 is rotatably connected with the top sliding plate 20. Locking mechanism 50 is positioned in the path of travel of top sled 20.
When the top sliding plate 20 moves along the first direction, the top sliding plate 20 drives the scissor telescopic frame 40 to shrink, and the scissor telescopic frame 40 drives the paired clamping plates 30 to move in opposite directions, so that the paired clamping plates 30 clamp the clamped piece accommodated in the accommodating space. At the same time, top slide 20 moves main slide 10 in the first direction via pair of clamp plates 30 so that top slide 20 is coupled to locking mechanism 50, locking mechanism 50 locking the current position of top slide 20.
According to the technical scheme provided by the embodiment of the invention, through the movement of the top sliding plate 20, the top sliding plate 20 drives the paired clamping plates 30 to move in opposite directions through the scissor telescopic frame 40, so that the paired clamping plates 30 can clamp the clamped piece. The accommodation space formed by the paired clamping plates 30 and the top slide plate 20 is adjustable so as to be able to accommodate a variety of clamped pieces. And the paired clamping plates 30 synchronously move, and the top sliding plate 20 drives the main sliding plate 10 to move through the paired clamping plates 30, so that the clamped piece is clamped at the central position of the device. The clamping process is simple and quick, and the use is more humanized, so that the use experience of a user is improved.
Taking the clamped piece as a mobile phone for example, referring to fig. 1 and 2, the mobile phone transversely enters the accommodating space along the arrow a direction in fig. 1 and 2. First, the side wall of the mobile phone contacts the top sliding plate 20, so as to drive the top sliding plate 20 to move along the arrow a direction, wherein the arrow a direction is the first direction.
As shown in fig. 2, in the initial state, the paired clamping plates 30 are relatively far from each other, and the top slide 20 is relatively close to the paired clamping plates 30. When the top slide plate 20 moves along the arrow a direction (the first direction), the top slide plate 20 drives the scissor telescopic frame 40 to shrink, and the scissor telescopic frame 40 drives the paired clamping plates 30 to move in opposite directions, namely, the paired clamping plates 30 respectively move along the arrow B and the arrow C in fig. 2, so that the paired clamping plates 30 clamp the mobile phone accommodated in the accommodating space, and the purpose of clamping the mobile phone is achieved. After the pair of clamping plates 30 clamps the cell phone, the main slide 10, the top slide 20, the clamping plates 30 and the cell phone are integrated. Then the mobile phone continues to move along the direction of arrow A, the mobile phone drives the top slide plate 20, the top slide plate 20 drives the clamping plate 30, the clamping plate 30 drives the main slide plate 10, the whole moves along the direction of arrow A, the whole moves to the position where the top slide plate 20 is connected with the locking mechanism 50, and the locking mechanism 50 locks the current position of the top slide plate 20. So far, the mobile phone clamping process is finished.
When the hand phone is released, locking mechanism 50 is released to lock top slide 20, and main slide 10 and top slide 20 are moved in opposite directions to the first direction until they return to the initial positions. When the top slide plate 20 returns along the opposite direction of the first direction, the scissor telescopic frame 40 also returns from the contracted state to the expanded state, and the scissor telescopic frame 40 drives the paired clamping plates 30 to move to the initial positions along the opposite directions of the arrow B and the arrow C respectively, so that the release of the mobile phone is completed.
The clamping device provided by the embodiment of the invention is further described in detail below.
Referring to fig. 1 and 3, in one embodiment of the present invention, the scissors assembly 40 includes a plurality of scissors rods 41, the plurality of scissors rods 41 being sequentially cross-hinged and defining a plurality of end hinge points 42 and a plurality of middle hinge points 43. The scissors telescoping 40 is connected to the clamping plate 30 by a middle hinge point 43 at both ends. The scissors jack 40 is rotatably connected to the top slide 20 by an end hinge point 42 towards one side of the top slide 20. The middle hinge point 43 is a hinge point located on a symmetry axis of the scissors telescopic frame 40 in the length direction, and the end hinge points 42 are hinge points on two sides of the symmetry axis of the scissors telescopic frame 40 in the length direction.
The clamping plates 30 are connected through the middle hinging points 43, so that the opening and closing amplitude of the fork rods 41 positioned at the two ends of the fork expansion frame 40 can be maximized, and the expansion amplitude of the fork expansion frame 40 can be maximized, so that the clamping of the clamped pieces with various different specifications can be realized. The top slide 20 is connected to the scissors jack 40 via a hinge point 42 at an end of the scissors jack 40, which drives the scissors jack 40 to retract when the top slide 20 moves in the first direction.
The connection of the top slide 20 to the scissor jack 40 may include a variety of ways, one of which is that the top slide 20 is connected to the end hinge point 42 of the scissor jack 40 via a transfer shaft. Alternatively, referring to fig. 1 and 3, at least one connecting rod 60 is provided on the top sled 20. One end of the connecting rod 60 is rotatably connected with the top slide plate 20, and the other end is rotatably connected with an end hinging point 42 of the scissors telescopic frame 40 towards one side of the top slide plate 20. When the top slide plate 20 moves, the scissor jack 40 is driven to retract or expand by the connecting rod 60. The number of the connection rods 60 may be one or more, and when the connection rods 60 are one, the connection rods 60 may be connected to the end hinge point 42 located at the middle position of the scissors jack 40. When the number of the connecting rods 60 is plural, the plurality of connecting rods 60 may be connected to the end hinge points 42 located at the two sides of the middle position of the scissors telescoping frame 40 when the number of the connecting rods 60 is plural, and the plurality of connecting rods 60 may be connected to the end hinge points located at the middle position of the scissors telescoping frame 40 and the end hinge points 42 located at the two sides of the middle position when the number of the connecting rods 60 is odd.
Further, to achieve the automatic restoration of the scissor jack 40 to the deployed state when the locking mechanism 50 releases the locking of the jack slide 20, the user is prevented from manually restoring. In one possible embodiment of the present invention, the scissors jack 40 is provided with a first elastic member 44. The two ends of the first elastic member 44 are respectively connected to two end hinge points 42, wherein the two end hinge points 42 connecting the first elastic member 44 are mirror symmetrical with respect to the symmetry axis of the scissors jack 40 in the length direction. When the top sliding plate 20 drives the scissor jack 40 to retract, the first elastic member 44 provides restoring force for the scissor jack 40. After the lock of the top slide 20 is released by the lock mechanism 50, the scissors jack 40 returns to the expanded state by the restoring force of the first elastic member 44.
For example, when the top sliding plate 20 moves along the first direction, the top sliding plate 20 drives the scissor jack 40 to retract, and the first elastic member 44 deforms, so that the first elastic member 44 provides a restoring force, i.e. an expanding force, for the scissor jack 40. When the locking mechanism 50 releases the locking of the top slide 20, the scissors telescopic frame 40 can be restored to the original position, i.e., to the unfolded state, by the restoring force of the first elastic member 44. In an embodiment of the present invention, the first elastic member 44 includes, but is not limited to, a tension spring, a compression spring, a spring plate, and the like. Taking the first elastic member 44 in fig. 1 and fig. 3 as a tension spring as an example, when the top sliding plate 20 moves along the first direction, the end hinge point 42 of the scissor telescopic frame 40 drives the scissor telescopic frame 40 to shrink, and at this time, the tension spring is stretched, and the tension spring is deformed to generate a restoring force. When the lock mechanism 50 releases the lock of the top slide plate 20, the top slide plate 20 moves in the opposite direction to the first direction by the restoring force of the tension spring until returning to the original position, at which time the scissors jack 40 returns to the expanded state by the restoring force of the tension spring.
Further, in order to prevent the first elastic member 44 from occupying additional space of the clamping device, in one embodiment of the present invention, the main slide plate 10 is provided with a receiving groove 11 extending in the moving direction of the top slide plate 20, and the first elastic member 44 is disposed in the receiving groove. The accommodating groove 11 extends along the moving direction of the top sliding plate 20, and the first elastic piece 44 deforms along the extending direction of the accommodating groove 11, so that no extra space is occupied, and the structure of the whole device is more compact.
Referring to fig. 1, 3 and 4, in order to define the moving direction of the top slide 20, in one embodiment of the present invention, the main slide 10 is provided with first positioning blocks 12 at positions corresponding to opposite ends of the top slide 20, respectively. The side of the first positioning block 12 facing the top slide plate 20 is provided with a first slide rail 13 extending in the sliding direction of the top slide plate 20. The top slide plate 20 is provided with a first slide rail 21 matched with the first slide rail 13 for use at a position corresponding to the first slide rail 13, and the first slide rail 21 can reciprocate along the extending direction of the first slide rail 13. In one implementation, a side of the first positioning block 12 facing the top sliding plate 20 is provided with a groove recessed away from the top sliding plate 20, and the groove is the first slideway 13. By the first slide 13 on the first positioning block 12, it is defined that the first slide rail 21 can only move along the extending direction of the first slide 13, preventing displacement of the first slide rail 21 in other directions relative to the main slide 10. Further, to prevent the first slide rail 21 from moving out of the first slide rail 13 along the opposite direction of the first direction, a limiting portion is disposed at one end of the first slide rail 13 near the clamping plate 30 to prevent the first slide rail 21 from moving out of the first slide rail 13. Of course, the first slide 13 may also be provided on the top slide 20, and the first slide rail 21 on the first positioning block 12.
Further, in one possible embodiment of the present invention, the top slide 20 includes a first bottom plate 22 and a first side plate 23 disposed on the first bottom plate 22. The first bottom plate 22 is rotatably connected with the scissors telescopic frame 40, and the first sliding rails 21 are arranged at two opposite ends of the first bottom plate 22. The first side plate 23 forms a receiving space with the pair of clamping plates 30. After the clamped piece enters the accommodating space, the clamped piece is abutted against the first side plate 23, and the top sliding plate 20 is driven to move through the first side plate 23. The first base plate 22 is used for connecting with the scissors telescopic 40 and the first positioning block 12. In addition, in order to prevent the first side plate 23 from damaging the clamped member when the first side plate 23 is in contact with the clamped member, a first buffer layer is provided on a side of the first side plate 23 in contact with the clamped member. The first buffer layer has elasticity, and when first curb plate 23 contacted by the clamp, first buffer layer received the extrusion and takes place deformation, offset the effort between first curb plate 23 and the clamp, prevented by the clamp by first curb plate 23 crowded wound.
Further, in order to define the moving direction of the clamping plate 30, and with continued reference to fig. 1,3 and 4, in one embodiment of the present invention, the main sliding plate 10 is provided with second positioning blocks 14 at positions corresponding to opposite ends of the clamping plate 30, respectively. The second positioning block 14 is provided with a second slideway 15 extending along the sliding direction of the clamping plate 30 on one side facing the clamping plate 30. The clamping plate 30 is provided with a second slide rail which is matched with the second slide rail 15 for use at a position corresponding to the second slide rail 15, and the second slide rail can reciprocate along the extending direction of the second slide rail 15. In one implementation manner, a recess, namely the second slideway 15, is arranged on one side of the second positioning block 14 facing the clamping plate 30 and recessed away from the clamping plate 30. The second slide rail is limited to move only along the extending direction of the second slide rail 15 by the second slide rail 15 on the second positioning block 14, so as to prevent the second slide rail from displacing in other directions relative to the main slide plate 10. Of course, the second slide 15 may also be disposed on the clamping plate 30, and the second slide rail is disposed on the second positioning block 14.
Further, in order to prevent the first slide rail 21 from moving out of the first slide rail 13 along the opposite direction of the first direction, a limiting portion is provided, and the second positioning block 14 can also prevent the first slide rail 21 from moving out of the first slide rail 13. Specifically, one of the second positioning blocks 14 located at opposite ends of the clamping plate 30 is connected to one end of the first positioning block 12 near the clamping plate 30, and extends beyond the first positioning block 12 to between the two first positioning blocks 12. The portion of the second positioning block 14 beyond the first positioning block 12 can limit the top sliding plate 20, so as to prevent the first sliding rail 21 from moving out of the first sliding way 13 along the opposite direction of the first direction.
Further, in one possible embodiment of the present invention, the clamping plate 30 optionally includes a second bottom plate 31 and a second side plate 32 disposed on the second bottom plate 31. The second bottom plate 31 is rotatably connected with the scissors telescopic frame 40, and the second sliding rails are arranged at two opposite ends of the second bottom plate 31. The pair of second side plates 32 forms a receiving space with the top slide plate 20. After the clamped members enter the accommodating space, the pair of clamping plates 30 clamp the clamped members through the second side plates 32. In order to prevent the second side plate 32 from damaging the clamped member when the second side plate 32 contacts the clamped member, second buffer layers are provided on both sides of the second side plate 32 contacting the clamped member. The second buffer layer has elasticity, and when second curb plate 32 contacted by the clamp, the second buffer layer received the extrusion and takes place deformation, offset the effort between second curb plate 32 and the clamp, prevented by the clamp by second curb plate 32 extrusion wound. The second bottom plate 31 is used for connecting with the scissors telescopic frame 40 and the second positioning block 14. After the second bottom plate 31 is connected with the second slideway 15 on the second positioning block 14 through the second slideway, the second bottom plate 31 can play a guiding role on the clamping plate 30 to prevent the clamping plate 30 from shifting in the moving direction, so that the force of the second side plate 32 clamped on the clamped piece shifts, and the clamping of the clamped piece is not firm.
Further, in one possible embodiment of the present invention, the main slider 10 is provided with a second elastic member. One end of the second elastic member is fixed, and the other end is connected with the main sliding plate 10. The first elastic member 44 provides a restoring force to the main slider 10 when the main slider 10 moves in the first direction. After the lock of top slide 20 is released by lock mechanism 50, main slide 10 returns to the original position under the restoring force of the second elastic member. The second elastic member includes, but is not limited to, a tension spring, a compression spring, a shrapnel, and the like. Taking the second elastic member as a tension spring as an example, after the top sliding plate 20 drives the pair of clamping plates 30 to clamp the clamped member accommodated in the accommodating space, the main sliding plate 10 is driven to move along the first direction continuously along the first direction. At this time, the main slider 10 pulls the tension spring (i.e., the second elastic member), so that the tension spring is deformed to generate a restoring force. When the lock mechanism 50 releases the lock of the top slide 20, the main slide 10 moves in the opposite direction to the first direction by the restoring force of the tension spring until returning to the original position. Further, in order to prevent the second elastic member from occupying an additional space, in one embodiment of the present invention, the main slider 10 is provided with a mounting groove extending in the moving direction of the main slider 10, and the second elastic member is disposed in the mounting groove. The mounting groove extends along the moving direction of the main sliding plate 10, and the second elastic member deforms along the extending direction of the mounting groove, so that no additional space is occupied, and the structure of the whole device is more compact.
With continued reference to fig. 1 and 3, to further integrate the clamping device, the clamping device further includes a securing plate 70. The main slider 10 is slidably disposed on the fixed plate 70. Locking mechanism 50 is disposed on fixed plate 70. The various components of the clamping device can be integrated together by the securing plate 70 so that the clamping device is integrated. Meanwhile, in order to prevent the main slider 10 from sliding out of the fixing plate 70 when moving in the opposite direction of the first direction, the fixing plate 70 is provided with a stopper 71, and the stopper 71 is located on the path along which the main slider 10 moves in the opposite direction of the first direction to define the maximum distance along which the main slider moves.
To achieve a limitation of the movement direction of the main slide 10, see fig. 1,3 and 4, a third positioning block 72 is provided at a side of the fixing plate 70 facing the main slide 10. The third positioning block 72 is provided with a third slide rail 73 extending in the sliding direction of the main slide plate 10. The position of the main slide plate 10 corresponding to the third slide way 73 is provided with a third slide rail 16 matched with the third slide way 73, and the third slide rail 16 can reciprocate along the extending direction of the third slide way 73. In one implementation, the side of the third positioning block 72 facing the main slide 10 is provided with a recess recessed away from the main slide 10, i.e. the third slide 73. The third rail includes a connection plate and a slide plate, one end of the connection plate is connected with the main slide plate 10, the other end is connected with one end of the slide plate, and the other end of the slide plate extends to the third slide rail 73. After the slide plate extends into the third slide 73, the third slide 73 defines that the third slide rail 16 can only move along the extending direction of the third slide 73, and prevents the first slide rail 21 from displacing in other directions relative to the main slide 10. At the same time, the third slide rail 16 is prevented from moving out of the third slide rail 73 in the opposite direction to the first direction by the stopper 71 to limit the maximum distance of movement of the main slider. Of course, the third slide rail 73 may be disposed on the main slide plate 10, and the third slide rail 16 may be disposed on the fixed plate 70.
In embodiments of the present invention, the implementation of locking mechanism 50 includes a plurality of ways, and one possible way is that, referring to fig. 1 and 3, locking mechanism 50 includes a locking lever 51 and a third elastic member 52. One end of the third elastic member 52 is fixed, and the other end is connected to the lock lever 51. One end of the locking lever 51 is provided with a first locking portion 53, and a second locking portion 24 that is used in a matching manner with the first locking portion 53 is provided on the top slide 20 at a position corresponding to the first locking portion 53. Locking and unlocking of the top slide 20 can be achieved by the reciprocating movement of the locking lever 51. The third elastic member 52 can automatically lock the top slide plate 20 and automatically return the locking lever 51 to the initial position after unlocking the main slide plate 10. The first fastening portion 53 and the second fastening portion 24 include, but are not limited to, hooks, and the hook portions of the first fastening portion 53 and the hook portions of the second fastening portion 24 have opposite bending directions.
For example, the third elastic member 52 includes, but is not limited to, a tension spring, a compression spring, a spring plate, and the like. Taking the third elastic member 52 as an example of a tension spring, one end of the tension spring is fixedly connected to the fixing plate 70, and the other end is connected to the locking lever 51. The lock lever 51 is reciprocally movable in the direction of arrow D in fig. 1. The top slide 20 drives the main slide 10 to move along the first direction, when the second fastening portion 24 on the top slide 20 contacts with the first fastening portion 53, the second fastening portion 24 extrudes the first fastening portion 53, so that the locking rod 51 moves along the arrow D direction, and the third elastic member 52 deforms. When the second fastening portion 24 exceeds the first fastening portion 53, the locking lever 51 moves in the opposite direction of the arrow D under the restoring force of the third elastic member 52, so that the first fastening portion 53 is fastened to the second fastening portion 24, so that the locking lever 51 locks the current position of the top sliding plate 20.
When the user needs to unlock the top slide 20, the locking lever 51 can be moved in the direction of arrow D by an external force to separate the second locking portion 24 from the first locking portion 53, and at this time, the locking lever 51 unlocks the top slide 20. When the external force is removed, the lock lever 51 moves in the opposite direction of the arrow D by the restoring force of the third elastic member 52, returning to its original position.
