Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a locking structure of an office cabinet. Background Art

[0002] The prior art, such as the Chinese utility model patent document with publication number CN205976799U, discloses an office furniture cabinet door lock structure, including a cabinet body, wherein the cabinet body is provided with a top plate, a bottom plate and a cabinet door, and is characterized in that a lock body is installed on the cabinet door, the lock core end of the lock body is a gear, a vertically arranged left rack is engaged on the left side of the gear, and a vertically arranged right rack is engaged on the right side of the gear, the upper end of the left rack is connected to the upper locking rod, and the lower end of the right rack is connected to the lower locking rod, and the top end of the upper locking rod and the bottom end of the lower locking rod are both hinged with lock hooks, and the lock hooks include a bent hook and a horizontal section, the free end of the horizontal section is hinged to the cabinet door, and a card slot matching the bent hook is provided on the top plate and the bottom plate; driven by the gear at the end of the lock core, the upper locking rod and the lower locking rod always move in opposite directions, thereby realizing the simultaneous closing and opening of the upper and lower lock hooks.

[0003] Based on the above, in the prior art, due to the problem of the rotation direction of the lock hook, the upper and lower lock hooks need to be driven by an upper lock rod and a lower lock rod respectively. When locking or unlocking, the upper lock rod and the lower lock rod move in opposite directions. This structural arrangement requires the use of a gear and two racks for transmission. The gear and rack need to be manufactured using a mold through injection molding. The mold manufacturing cost is high and is not conducive to reducing production costs. Further improvement is needed. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a locking structure for an office cabinet.

[0005] A locking structure for an office cabinet designed for this purpose comprises a cabinet body and a cabinet door hingedly arranged on the cabinet body, a lock hook space being provided on the front side of the cabinet body, an opening being provided on the front side of the lock hook space, a lock hook being rotatably provided on the cabinet door and capable of extending through the opening into the lock hook space, a rotating lock rod being rotatably provided on the cabinet door, the rotating lock rod being connected to the lock hook and capable of driving the lock hook to rotate, a lock set being provided on the cabinet door, the lock set being transmission-connected to a transmission assembly, and the transmission assembly being transmission-connected to the rotating lock rod;

[0006] The hinge axis of the cabinet door and the rotation axis of the lock hook are arranged parallel to each other;

[0007] The transmission assembly is configured to be driven by the lock to drive the rotating lock rod to rotate forward or reverse, so as to drive the lock hook to abut against the lock hook space for locking or unlocking.

[0008] Preferably, the transmission assembly includes a fixed frame, a moving member arranged on the fixed frame to move left and right, and the moving member is provided with a first slot and a second slot;

[0009] The power output shaft of the lock is connected to a turntable, and an eccentric shaft is provided on the turntable, and the eccentric shaft is movably inserted into the first slot;

[0010] The rotating lock rod is connected to a transmission rod, and the transmission rod is movably inserted in the second slot.

[0011] Preferably, a guide groove is provided on the fixing frame, and the movable member is arranged in the guide groove for leftward and rightward movement.

[0012] Preferably, the lock is an electronic lock.

[0013] Preferably, a mounting seat is provided on the cabinet door, and the lock hook is rotatably provided on the mounting seat.

[0014] Compared to existing technologies, the hinge axis of the cabinet door and the rotation axis of the lock hook are arranged parallel to each other. With this design, a single rotating lock rod can simultaneously drive the upper and lower lock hooks to rotate to achieve locking or unlocking. Because only one rotating lock rod is driven, the entire transmission assembly does not need to use a gear and rack, which optimizes component production, reduces production costs, and meets production requirements.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figures 1-6 A locking structure of an office cabinet includes a cabinet body 10 and a cabinet door 20 hingedly arranged on the cabinet body 10, wherein a lock hook space 110 is provided on the front side of the cabinet body 10, and an opening 100 is provided on the front side of the lock hook space 110. A lock hook 50 is rotatably provided on the cabinet door 20 and can pass through the opening 100 and extend into the lock hook space 110. A rotating lock rod 400 is rotatably provided on the cabinet door 20, and the rotating lock rod 400 is connected to the lock hook 50 and can drive the lock hook 50. The lock hook 50 rotates, and a lock 30 is provided on the cabinet door 20. The lock 30 is transmission-connected to a transmission assembly 40, and the transmission assembly 40 is transmission-connected to the rotating lock rod 400. The hinge axis of the cabinet door 20 and the rotation axis of the lock hook 50 are arranged parallel to each other. The transmission assembly 40 is configured to be driven by the lock 30 to drive the rotating lock rod 400 to rotate forward or reverse, so as to drive the lock hook 50 to abut against the lock hook space 110 for locking or unlocking.

[0023] Based on the above embodiment, the hinge axis of the cabinet door and the rotation axis of the lock hook are arranged parallel to each other. With this design, a single rotating lock rod can simultaneously drive the upper and lower lock hooks to rotate to achieve locking or unlocking. Because only a single rotating lock rod is driven, the entire transmission assembly does not need to use a gear and rack, which optimizes component production, reduces production costs, and meets production requirements.

[0024] See also Figure 4 and Figure 6 The transmission assembly 40 includes a fixed frame 410, a movable member 420 is arranged on the fixed frame 410 for left and right movement, and a first slot 430 and a second slot 440 are provided on the movable member 420; the power output shaft of the lock 30 is connected to a turntable 310, and an eccentric shaft 320 is provided on the turntable 310, and the eccentric shaft 320 is movably inserted in the first slot 430; the rotating lock rod 400 is connected to a transmission rod 450, and the transmission rod 450 is movably inserted in the second slot 440. When the lock 30 drives the turntable 310 to rotate, the eccentric shaft 320 rotates in a circle around the power output shaft of the lock 30. When it rotates, the eccentric shaft 320 moves in the first slot 430 to drive the moving part 420 to move left or right. When the moving part 420 moves left and right, it drives the transmission rod 450 to drive the rotating lock rod 400 to rotate forward or reverse, thereby driving the lock hook 50 to rotate to achieve locking or unlocking.

[0025] See also Figure 6 The first slot 430 extends in the up-down direction, and the second slot 440 extends in the left-right direction.

[0026] See also Figure 6The fixing frame 410 is provided with a guide groove 411 , and the moving member 420 is arranged in the guide groove 411 to move left and right.

[0027] In the present invention, the lock 30 is an electronic lock. The electronic lock adopts an existing commercially available product. After the password is entered or other identification methods are used to identify and unlock the lock, the lock 30 drives its power output shaft to rotate.

[0028] See also Figure 5 The cabinet door 20 is provided with a mounting seat 500 , and the lock hook 50 is rotatably provided on the mounting seat 500 .
