Lock transmission box

Abstract

The utility model discloses a lock transmission box which comprises a lower support, the two side edges of the lower support are bent and extend towards one side, toothed plate compression spring pieces are embedded in the corners of the two sides in a bent part on one face of the lower support, and a transmission square rod used for transmitting a lock is movably connected to the bottom side of the surface of the lower support in a penetrating mode. A toothed plate piece which slides in a meshing mode is installed on one face of the lower support, so that when a transmission square rod rotates, a gear piece moves the toothed plate piece in an open tooth groove, a toothed plate compression spring piece can be compressed through a protruding supporting block, and when the gear piece rotates to the position, where a tooth block is arranged, in the inner wall of the open tooth groove, the toothed plate compression spring piece can be compressed. Therefore, the toothed plate part can be driven to rebound to an initial state by utilizing the rebound resilience of the toothed plate pressure spring part, and the toothed plate part can be kept in horizontal movement without displacement through the elastic reset driving of the two toothed plate spring parts on the toothed plate part; and meanwhile, the double-toothed-plate pressure spring piece cannot generate pressure or cannot generate the problem of breakage and damage caused by increased tensile force in the repeated use process.

Description

Technical Field

[0001] The utility model belongs to the technical field of locks, and in particular relates to a lock transmission box. Background Art

[0002] At present, people have higher and higher requirements for the experience of furniture, especially for a type of furniture used to store items, such as drawer cabinets, which are generally connected to the cabinet body through freely sliding drawer guides, so that the drawer can be close to the furniture after closing, which looks neat and beautiful. The existing locks can make the drawer pop out automatically by pressing the rebounder. However, the drawer guide pressing the rebounder lacks a buffer mechanism. When the drawer pops out, due to excessive pushing or popping force, in the absence of a buffering effect, the items in the drawer are easily displaced due to rapid movement and produce a knocking sound.

[0003] To this end, a device with a rebound structure with a publication number of "CN219249595U" includes a shell, the shell is provided with an elastic reset mechanism, the elastic reset mechanism is provided with a rebound component extending out of the shell, and the rebound component is provided with a first abutment end and a second abutment end; contacting and pushing the rebound component from the first abutment end can cause the rebound component to push the elastic reset mechanism to move in the shell; contacting and pushing the rebound component from the second abutment end can cause the rebound component to retract toward the inside of the shell, and contacting the rebound component from the first abutment end so that the rebound component pushes the elastic reset mechanism to move, so that the thrust applied to the first abutment end is better transmitted to the elastic reset mechanism, and contacting the rebound component from the second abutment end so that the rebound component retracts toward the inside of the shell, so that part of the thrust applied to the second abutment end is converted into elastic potential energy when the rebound component retracts, thereby forming a certain buffering effect.

[0004] However, for the above-mentioned device with a rebound structure, although the first abutting end contacts the rebound component so that the rebound component pushes the elastic reset mechanism to move, the following obvious defects still exist during use: the rebound components in the above-mentioned device are reset by pulling with a spring, and only one side is provided with a tension spring to reset the tooth plate, which can easily cause the internal tooth plate position to shift. At the same time, the tension spring is prone to breakage and damage due to increased pressure or tension during use. Utility Model Content

[0009] Preferably, a raised support block is extended outwardly from the corner of the bottom side of one side of the tooth plate member, and the raised support block is pressed into one end of the tooth plate compression spring member, so that the tooth plate member can compress the tooth plate compression spring member during movement and release the rebound effect.

[0010] Preferably, a limiting groove with a strip structure is opened at the center position of one side of the bracket, and an outer protrusion in the sliding limiting groove is extended outward from the upper end of the open tooth groove on one side of the tooth plate, which can enable the tooth plate to maintain stability in the transmission box when moving.

[0011] Preferably, a groove is provided on one end surface of the transmission square rod, and a square rod spring is sleeved on one end of the transmission square rod located outside the bracket, so that the transmission square rod can be restored to its original state after rotation.

[0012] Preferably, one end of the transmission square rod is sleeved with a shaft retaining ring, and the shaft retaining ring is clamped in the groove to restrict the square rod spring part, so that the square rod spring part can pass through the shaft retaining ring to elastically reset the transmission square rod and prevent it from falling off.

[0013] Preferably, the inner surface of the bending corner of the lower bracket is symmetrically provided with a compression spring groove which is recessed outward, and the tooth plate compression spring member is installed in the compression spring groove, so that the stability of the compression rebound of the tooth plate member can be ensured after the tooth plate compression spring member is used, and the problem of decreased elasticity of the tooth plate compression spring will not occur.

When the gear plate is moved, the raised support block can be used to compress the tooth plate compression spring part. When the gear plate is rotated to the position where there is a tooth block on the inner wall of the open tooth groove, the resilience of the tooth plate compression spring part can be used to drive the tooth plate part to rebound to its initial state. The elastic reset drive of the tooth plate part by the two tooth plate spring parts can keep the position of the tooth plate part moving horizontally without shifting. At the same time, the double tooth plate compression spring part will not produce the problem of increased pressure or tension causing breakage and damage during repeated use, thereby further improving the stability and reliability of the transmission of the lock transmission box.
