Embodiments of the present invention will be described in detail below with reference to the accompanying drawings and embodiments, so that the implementation process of solving the technical problem and achieving the technical effect by applying the technical means of the embodiments of the present invention can be fully understood and implemented, and the structure of the present invention will be further described 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.

An embodiment of the utility model provides a clamping device, include: a main slide 10, a top slide 20, at least one pair of clamping plates 30 with synchronizing rods 31 and a locking mechanism 40.

Wherein the top slide 20 is movably connected to the main slide 10. The pair of clamping plates 30 is movably coupled to the main slide 10, the pair of clamping plates 30 forms a receiving space with the top slide 20, and one end of the synchronizing bar 31 is rotatably coupled to the clamping plates 30 and the other end thereof is rotatably coupled to the top slide 20. The locking mechanism 40 is located on the moving path of the top slide 20.

When the top sliding plate 20 moves along the first direction, the top sliding plate 20 drives the pair of clamping plates 30 to move towards each other through the synchronizing rod 31, so that the pair of clamping plates 30 can clamp the clamped piece accommodated in the accommodating space; at the same time, the top slide 20 moves the main slide 10 in the first direction by the pair of clamping plates 30 so that the top slide 20 is coupled with the locking mechanism 40, and the locking mechanism 40 locks the current position of the top slide 20.

The embodiment of the utility model provides a technical scheme, when the removal through top slide 20, accessible synchronizing bar 31 drives mated splint 30 and removes in opposite directions for mated splint 30 can realize to the centre gripping by the clamping piece, can the adaptation multiple by the clamping piece, so that mated splint 30 presss from both sides the tight holding by the clamping piece in the accommodation space. And simultaneously with the synchronous movement of the pair of clamping plates 30, the top sliding plate 20 drives the main sliding plate 10 through the pair of clamping plates 30 to ensure 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 fig. 2, the mobile phone enters the accommodating space laterally along the direction of arrow a in fig. 1. First, the sidewall of the mobile phone contacts the top slide plate 20, so as to drive the top slide plate 20 to move along the direction of arrow a, where the direction of arrow a is the first direction.

As shown in fig. 2, in the initial state, the pair of clamping plates 30 are spaced far apart from each other, and the top slide plate 20 is relatively close to the pair of clamping plates 30. When the top sliding plate 20 moves along the arrow a direction (the first direction), the top sliding plate 20 drives the paired clamping plates 30 to move oppositely through the synchronizing rod 31, that is, the paired clamping plates 30 move along the arrow B and the arrow C directions in fig. 2, respectively, so that the paired clamping plates 30 clamp the mobile phone accommodated in the accommodating space, thereby achieving the purpose of clamping the mobile phone. After the pair of clamping plates 30 clamps the mobile phone, the main slide 10, the top slide 20, the clamping plates 30 and the mobile phone are integrated. Then, when the mobile phone continues to move along the direction of the arrow a, the mobile phone drives the top sliding plate 20, the top sliding plate 20 drives the clamping plate 30, the clamping plate 30 drives the main sliding plate 10, the whole mobile phone moves along the direction of the arrow a, and the mobile phone moves until the top sliding plate 20 is connected with the locking mechanism 40, and the locking mechanism 40 locks the current position of the top sliding plate 20. And finishing the mobile phone clamping process.

When the mobile phone is released, the locking mechanism 40 is released to lock the top slide plate 20, and the main slide plate 10 and the top slide plate 20 both move in the opposite direction of the first direction until they return to the initial position. When the top slide 20 is returned, the pair of clamping plates 30 are also moved to the initial positions in the opposite directions of arrows B and C, respectively.

The following provides a further detailed description of the clamping device according to the embodiment of the present invention.

To achieve the definition of the moving direction of the top slide 20, referring to fig. 1, 3 and 4, in an achievable embodiment of the present invention, the main slide 10 is provided with first positioning blocks 11 at positions corresponding to the opposite ends of the top slide 20. One side of the first positioning block 11 facing the top sliding plate 20 is provided with a first slideway 12 extending along the sliding direction of the top sliding plate 20. A first slide rail 21 matched with the first slide way 12 for use is arranged on the top slide plate 20 at a position corresponding to the first slide way 12, and the first slide rail 21 can reciprocate along the extending direction of the first slide way 12. In an implementation manner, a side of the first positioning block 11 facing the top slide plate 20 is provided with a groove recessed away from the top slide plate 20, and the groove is the first slideway 12. The first slide rail 12 on the first positioning block 11 limits the first slide rail 21 to move only along the extending direction of the first slide rail 12, and prevents the first slide rail 21 from displacing in other directions relative to the main sliding plate 10. Further, in order to prevent the first slide rail 21 from moving out of the first slide rail 12 in the first slide rail 12 along the opposite direction of the first direction, a limiting portion is disposed at one end of the first slide rail 12 close to the clamping plate 30 to prevent the first slide rail 21 from moving out of the first slide rail 12. Of course, the first slideway 12 may be arranged on the top sliding plate 20, and the first slide rail 21 is arranged on the first positioning block 11.

Further, in an achievable embodiment of the present invention, the top slide plate 20 comprises a first bottom plate 22 and a first side plate 23 arranged on the first bottom plate 22. The first base plate 22 is rotatably coupled to one end of the synchronization lever 31. The first slide rails 21 are disposed at opposite ends of the first base plate 22. 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 by the first side plate 23. The first bottom plate 22 is used to connect the synchronization rod 31 and the first positioning block 11. In addition, in order to prevent the first side plate 23 from damaging the clamped piece when the first side plate 23 is in contact with the clamped piece, a first buffer layer is arranged on one side of the first side plate 23 in contact with the clamped piece. The first buffer layer has elasticity, and when the first side plate 23 contacts with the clamped piece, the first buffer layer is extruded to deform, so that the acting force between the first side plate 23 and the clamped piece is offset, and the clamped piece is prevented from being extruded by the first side plate 23.

The connection between the first base plate 22 and the synchronizing bar 31 includes various ways, and one way to realize this is that, referring to fig. 1 and 3, the first base plate 22 is provided with a rotating shaft 24, and the synchronizing bar 31 on different clamping plates 30 is rotatably connected to the first base plate 22 through the same rotating shaft 24. For example, the rotation shaft 24 is disposed at the center of the first base plate 22, and when the top slide plate 20 moves in the first direction, the synchronization rod 31 and the top slide plate 20 rotate, the synchronization rod 31 and the clamping plates 30 also rotate, and at the same time, the top slide plate 20 drives the pair of clamping plates 30 to move toward each other. In this way, the required length of the synchronizing bar 31 is longer, and the moving range of the pair of clamping plates 30 towards or away from each other is larger, so that the clamping mechanism is suitable for clamped parts with more specifications.

Alternatively, the first base plate 22 is provided with a plurality of rotation shafts 24, and the synchronization rods 31 on different clamping plates 30 are rotatably connected to the first base plate 22 through different rotation shafts 24. For example, two rotation shafts 24 are provided, and the two rotation shafts 24 are arranged in mirror symmetry along the center of the first base plate 22. In this way, the required length of the synchronization rod 31 is short, and the manufacturing cost of the synchronization rod 31 can be effectively reduced.

Further, to realize the limitation of the moving direction of the clamping plate 30, with continued reference to fig. 1, 3 and 4, in an achievable embodiment of the present invention, the main sliding plate 10 is provided with second positioning blocks 13 at positions corresponding to the two opposite ends of the clamping plate 30. A second slide way 14 extending along the sliding direction of the clamping plate 30 is arranged on one side of the second positioning block 13 facing the clamping plate 30. A second slide rail matched with the second slide rail 14 is arranged at a position, corresponding to the second slide rail 14, on the clamping plate 30, and the second slide rail can reciprocate along the extending direction of the second slide rail 14. In an implementation manner, a side of the second positioning block 13 facing the clamping plate 30 is provided with a groove recessed away from the clamping plate 30, and the groove is the second slideway 14. The second slide rail 14 on the second positioning block 13 limits that the second slide rail can only move along the extending direction of the second slide rail 14, and prevents the second slide rail from moving relative to the main slide plate 10 in other directions. Of course, the second slide way 14 may also be disposed on the clamping plate 30, and the second slide rail is disposed on the second positioning block 13.

Further, in order to prevent the first slide rail 21 from moving out of the first slide rail 12 along the direction opposite to the first direction in the first slide rail 12, besides providing the limiting portion, the second positioning block 13 may also prevent the first slide rail 21 from moving out of the first slide rail 12. Specifically, one of the second positioning blocks 13 located at two opposite ends of the clamping plate 30 is connected to one end of the first positioning block 11 close to the clamping plate 30, and extends beyond the first positioning block 11 to extend between the two first positioning blocks 11. The portion of the second positioning block 13 beyond the first positioning block 11 can limit the top sliding plate 20, and prevent the first sliding rail 21 from moving out of the first sliding rail 12 along the opposite direction of the first direction.

Further, in an achievable embodiment of the invention, the clamping plate 30 comprises a second bottom plate 32 and a second side plate 33 arranged on the second bottom plate 32. The second base plate 32 is rotatably coupled to one end of the synchronization lever 31. The second slide rails are disposed at opposite ends of the second base plate 32. After the clamped piece enters the accommodating space, the pair of clamping plates 30 clamps the clamped piece through the second side plate 33. In order to prevent the second side plate 33 from damaging the clamped part when the second side plate 33 is in contact with the clamped part, a second buffer layer is arranged on two sides of the second side plate 33 in contact with the clamped part. The second buffer layer has elasticity, and when second curb plate 33 contacted with by the clamping piece, the second buffer layer received the extrusion and takes place deformation, has offset second curb plate 33 and the effort of being between the clamping piece, prevents to be crowded by second curb plate 33 by the clamping piece and hurts. The second bottom plate 32 is used for connecting the synchronization rod 31 and the second positioning block 13. The second base plates 32 are connected to the synchronizing bars 31 in such a manner that one synchronizing bar 31 is connected to each second base plate 32. After the second bottom plate 32 is connected with the second slide way 14 on the second positioning block 13 through the second slide way, the second bottom plate 32 can guide the clamping plate 30, so that the clamping plate 30 is prevented from deviating in direction when moving, and the force of the second side plate 33 clamped on the clamped part deviates, so that the clamped part is not firmly clamped.

With continued reference to fig. 1 and 3, further, in an achievable embodiment of the invention, the main slide 10 is provided with a first resilient member 15. One end of the first elastic member 15 is fixed and the other end is connected to the main slide 10. The main slide 10 is automatically returned to the original position by the first elastic member 15 when the locking mechanism 40 releases the locking of the roof slide 20, thereby preventing the user from manually returning. Specifically, the method comprises the following steps. The first elastic member 15 provides a restoring force to the main slide 10 when the main slide 10 moves in the first direction. After the locking mechanism 40 unlocks the top slide 20, the main slide 10 is returned to the original position by the restoring force of the first elastic member 15.

For example, the first elastic member 15 includes, but is not limited to, a tension spring, a compression spring, a spring plate, and the like. Taking the first elastic element 15 as a tension spring as an example, after the top sliding plate 20 drives the pair of clamping plates 30 to clamp the clamped element accommodated in the accommodating space, the top sliding plate drives the main sliding plate 10 to move along the first direction while continuing to move along the first direction. At this time, the main sliding plate 10 pulls the tension spring, so that the tension spring is deformed to generate restoring force. When the locking mechanism 40 releases the locking of the top slide 20, the main slide 10 is moved in the opposite direction of the first direction by the restoring force of the tension spring until it is restored to the original position.

Further, in order to prevent the first elastic member 15 from occupying extra space, in an embodiment of the present invention, the main sliding plate 10 is provided with a receiving groove 16 extending along the moving direction of the main sliding plate 10, and the first elastic member 15 is disposed in the receiving groove. The receiving groove 16 extends along the moving direction of the main sliding plate 10, and the first elastic member 15 deforms along the extending direction of the receiving groove 16, so that no additional space is occupied, and the structure of the whole device is more compact.

To further achieve the purpose of automatically returning the top slide 20 and the clamp plate 30 to the initial position when the locking mechanism 40 releases the lock of the top slide 20, manual return by the user is avoided. In an embodiment of the present invention, the paired clamp plates 30 are respectively provided with a second elastic member 34. The second elastic member 34 has one end fixed to the main slide 10 and the other end connected to the clamping plate 30. The second elastic member 34 provides a restoring force to the chucking plate 30 when the pair of chucking plates 30 are moved toward each other. After the locking mechanism 40 unlocks the top slide plate 20, the pair of clamping plates 30 are moved back to the initial position by the restoring force of the second elastic member 34.

For example, the second elastic element 34 includes, but is not limited to, a tension spring, a compression spring, a spring plate, a torsion spring, and the like. Taking the second elastic member 34 as an example of a torsion spring, the main sliding plate 10 is provided with a connecting column and a stop block, the torsion spring is sleeved on the connecting column, one end of the torsion spring abuts against the stop block, and the other end of the torsion spring is connected with the second bottom plate 32 of the clamping plate 30. When the top slide 20 moves in the first direction, the top slide 20 drives the pair of clamping plates 30 to move towards each other through the synchronizing bar 31. The clamping plate 30 needs to overcome the torsion of the torsion spring when moving, so that the torsion spring is deformed to generate restoring force. When the locking mechanism 40 releases the locking of the top slide 20, the pair of clamping plates 30 moves back under the restoring force of the torsion spring until returning to the original position. The pair of clamping plates 30, when moved away from each other, bring the top slide 20 back to the initial position.

To further integrate the clamping device, the clamping device further comprises a fixing plate 50. The main slide 10 is slidably disposed on the fixed plate 50. The locking mechanism 40 is provided on the fixed plate 50. The various components of the clamping device can be integrated together by the fixing plate 50, so that the clamping device is integrated. Meanwhile, in order to prevent the main slide 10 from slipping out of the fixed plate 50 when moving in the direction opposite to the first direction, a stopper 51 is provided on the fixed plate 50, and the stopper 51 is located on a path along which the main slide 10 moves in the direction opposite to the first direction to define a maximum distance that the main slide 10 moves.

To achieve the definition of the moving direction of the main sliding plate 10, referring to fig. 1, 3 and 4, in an achievable embodiment of the present invention, the fixing plate 50 is provided with a third positioning block 52 facing one side of the main sliding plate 10. The third positioning block 52 is provided with a third slide 53 extending in the sliding direction of the main slide 10 on a side facing the main slide 10. A third slide rail 17 matched with the third slide rail 53 is arranged at a position, corresponding to the third slide rail 53, on the main slide plate 10, and the third slide rail 17 can reciprocate along the extending direction of the third slide rail 53. In an implementation manner, a side of the third positioning block 52 facing the main sliding plate 10 is provided with a groove recessed away from the main sliding plate 10, and the groove is the third sliding way 53. The third slide rail 17 includes a connecting plate and a sliding plate, one end of the connecting plate is connected to the main slide plate 10, the other end is connected to one end of the sliding plate, and the other end of the sliding plate extends toward the third slide rail 53. After the sliding plate extends into the third sliding channel 53, the third sliding channel 53 limits the third sliding track 17 to move only along the extending direction of the third sliding channel 53, and prevents the first sliding track 21 from displacing in other directions relative to the main sliding plate 10. At the same time, the third slide rail 17 is prevented by the stopper 51 from moving out of the third slide way 53 in the opposite direction of the first direction within the third slide way 53 to define the maximum distance of movement of the main slide 10. Of course, the third slide way 53 may be disposed on the main sliding plate 10, and the third slide rail 17 may be disposed on the fixed plate 50.

With continued reference to fig. 1 and 3, in one realizable embodiment of the present disclosure, the locking mechanism 40 includes a locking lever 41 and a third resilient member 42. The locking and unlocking of the main slide 10 can be achieved by the reciprocating movement of the lock lever 41. The third elastic member 42 can automatically lock the main slide 10 and automatically return to the original position after the main slide 10 is unlocked. Specifically, one end of the third elastic member 42 is fixed, and the other end is connected to the lock lever 41. One end of the lock lever 41 is provided with a first engaging portion 43, and a second engaging portion 25 used in cooperation with the first engaging portion 43 is provided at a position of the top slide plate 20 corresponding to the first engaging portion 43. The first locking portion 43 and the second locking portion 25 include but are not limited to hooks, and the bending directions of the hook portion of the first locking portion 43 and the hook portion of the second locking portion 25 are opposite.

For example, the third elastic element 42 includes, but is not limited to, a tension spring, a compression spring, a spring plate, and the like. Taking the third elastic member 42 as a tension spring as an example, one end of the tension spring is fixedly connected to the fixed plate 50, and the other end is connected to the locking lever 41. The lock lever 41 is reciprocally movable in the direction of arrow D in fig. 1. The top slide plate 20 drives the main slide plate 10 to move along the first direction, and when the second latching portion 25 on the top slide plate 20 contacts with the first latching portion 43, the second latching portion 25 presses the first latching portion 43, so that the locking rod 41 moves along the direction of the arrow D, and the third elastic member 42 deforms. When the second latching portion 25 exceeds the first latching portion 43, the locking rod 41 moves in the opposite direction of the arrow D under the action of the restoring force of the third elastic member 42, so that the first latching portion 43 is engaged with the second latching portion 25, so that the locking rod 41 locks the current position of the top slide plate 20.

When the user needs to unlock the top slide plate 20, the locking lever 41 is moved in the direction of the arrow D by an external force to separate the second latching portion 25 from the first latching portion 43, and the locking lever 41 unlocks the top slide plate 20. When the external force disappears, the lock lever 41 moves in the direction opposite to the arrow D by the restoring force of the third elastic member 42, and returns to its original position.
