Locking device and precious metal recovery apparatus

Abstract

The application provides a locking device and a precious metal recovery equipment. The locking device comprises a fixing member, a driving member and at least one pair of locking plate structures. The locking plate structures are slidingly connected to the fixing member. The driving member has a driving end and a pushing end. The driving end is rotated relative to the fixing member under the action of external force. When the driving member is rotated, the pushing end pushes the locking plate structures to slide relative to the fixing member, so that the to-be-locked member is locked between the pair of locking plate structures to prevent displacement of the to-be-locked member. The driving end is deformed under the action of external force to buffer the external force, so that the external force is not too large to excessively lock the to-be-locked member by the locking plate structures and damage to the to-be-locked member is avoided. Meanwhile, the driving end is deformed under the action of external force, so that the requirement for assembly precision of the locking device is reduced.

[0056] Please see Figures 1 to 8 The locking device and the precious metal recovery equipment provided by the embodiments of the present application will be described below.

[0057] The first aspect of the present application is a locking device 10, which comprises a fixed part 11, a driving part 12, and at least one pair of locking piece structures 13. The driving part 12 is rotationally connected to the fixed part 11, and the driving part 12 has a driving end S1 and a pushing end S2. The driving end S1 is used to receive external force to make the driving part 12 rotate relative to the fixed part 11, and the pushing end S2 is used to push the locking piece structure 13 to slide relative to the fixed part 11 when the driving part 12 rotates relative to the fixed part 11. The locking piece structure 13 is connected to the fixed part 11, and at least one of the locking piece structures 13 in the pair of locking piece structures 13 can slide relative to the fixed part 11. Under the action of the driving end S1, the pair of locking piece structures 13 can move close to each other to lock the to-be-locked part between the pair of locking piece structures 13.

[0058] Specifically, in the embodiments of the present application, please refer to Figures 3 to 8 The fixed part 11 is a plate structure, and initially, the locking device 10 is in an unlocked state, and the distance between the two locking piece structures 13 in each pair of locking piece structures 13 is at a maximum value. The driving end S1 drives the driving part 12 to rotate relative to the fixed part 11 under the action of external force. During the rotation of the driving part 12 relative to the fixed part 11, the pushing end S2 pushes the locking piece structure 13 to slide relative to the fixed part 11 in the horizontal direction, so that the distance between the two locking piece structures 13 in the same pair of locking piece structures 13 is reduced, so as to lock the to-be-locked part between the pair of locking piece structures 13, thereby preventing the to-be-locked part from being displaced. At the same time, the driving end S1 deforms under the action of external force to buffer the external force, so as to prevent the external force from being too large to excessively lock the to-be-locked part by the locking piece structure 13, and avoid damaging the to-be-locked part by the locking piece structure 13. Moreover, the driving end S1 deforms under the action of external force, which reduces the requirement for assembly precision of the locking device 10.

[0059] In an embodiment of the present application, the locking device 10 further comprises a resilient part 14, one end of the resilient part 14 is connected to one of the locking piece structures 13 in the pair of locking piece structures 13, and the other end opposite to the one end is connected to the other locking piece structure 13. Under the action of the restoring force of the resilient part 14, the two locking piece structures 13 can move away from each other to unlock the to-be-locked part.

[0060] Specifically, in the embodiments of the present application, as preferred, please refer to Figures 3 to 5Each pair of the lock piece structures 13 includes two lock piece structures 13, the two lock piece structures 13 in the same pair of the lock piece structures 13 are oppositely arranged, and two sleeve joints 131 are arranged on each of the lock piece structures 13, the two sleeve joints 131 on the same lock piece structure 13 are symmetrical about the sliding direction of the lock piece structure 13, and the sleeve joints 131 on the two lock piece structures 13 in the same pair of the lock piece structures 13 are oppositely arranged. The elastic member 14 is a spring 141, and the two ends of the spring 141 are sleeved between the two oppositely arranged sleeve joints 131. Under the action of an external force, the two lock piece structures 13 in the same pair of the lock piece structures 13 are close to each other to lock the object to be locked, and the two lock piece structures 13 in the same pair of the lock piece structures 13 are close to each other to compress the spring 141. After the external force acting on the driving end S1 disappears, under the action of the elastic force of the spring 141, the two lock piece structures 13 in the same pair of the lock piece structures 13 return to the initial position, so as to realize unlocking of the object to be locked.

[0061] In an embodiment of the present application, the driving member 12 includes a connecting block 121, a driving rod 122 and a pushing piece 123. The connecting block 121 is rotationally connected to the fixed member 11.

One end of the pushing piece 123 is connected to the connecting block 121, and the other end of the pushing piece 123 is a pushing end S2. The extension direction of the driving rod 122 is arranged at an angle with the extension direction of the pushing piece 123, and the driving rod 122 is a rigid rod or an elastic rod.

Under the action of an external force, the driving rod 122 drives the connecting block 121 to rotate relative to the fixed member 11, so that the connecting block 121 drives the pushing block to rotate about the rotation axis of the connecting block 121, and the pushing block drives the lock piece structure 13 to slide relative to the fixed frame when rotating.

[0063] As preferred, the driving rod 122 is an elastic rod. Compared with a rigid rod, when the external force is too large, the elastic rod deforms, and the reaction force generated by the deformation of the elastic rod can offset part of the external force, thereby preventing the lock piece structure 13 from being excessively locked to the object to be locked due to the external force being too large, and avoiding damage to the object to be locked by the lock piece structure 13. Moreover, the deformation of the elastic rod under the action of the external force can also reduce the requirement for assembly precision of the lock piece structure 13.

When the external force disappears, by arranging the spring 141 at both ends of the half opening structure 132, the movement direction of the two lock piece structures 13 in the process of returning to the initial position is prevented from deviating.

[0067] In an embodiment of the present application, the driving member 12 and the lock piece structure 13 are located on the same side of the fixing member 11, or the driving member 12 and the lock piece structure 13 are located on opposite sides of the fixing member 11.
