AI Technical Summary

Problems solved by technology

However, once the limit mechanism runs into an obstacle or the motor continues to work after the limit mechanism moves to the limit position, the rotating shaft of the motor will continue to rotate, but the limit mechanism cannot be driven to move. A huge reaction force is generated, causing the rotating bearing to be subjected to a large torque, and the rotating shaft of the motor is prone to breakage
[0006] Once the rotating shaft of the motor breaks, it will not be able to drive the limit mechanism to move, which will affect the normal movement of the lock tongue, resulting in the combination lock not being able to open and close normally, seriously affecting the safe use of ATM equipment

Embodiment Construction

[0034] The combination lock of the present invention is installed on the cabinet door of ATM equipment or other equipment that needs to be kept secret. It can be a static combination lock, which can be opened with a relatively fixed password, or a dynamic combination lock, which needs to be input every time it is opened. Change password. Of course, it can also be a dynamic and static coded lock, that is, the coded mode of the coded lock can be a dynamic coded mode or a static coded mode, and the user can change the coded mode of the coded lock according to actual needs.

[0035] see figure 1 and figure 2 , the combination lock is composed of a controller 10 and a lock 30, the controller 10 is roughly cylindrical, the lock 30 is located at the rear side of the controller 10, and the lock 30 is roughly square. And, between the controller 10 and the lock 30 through the rotating shaft 50 ( Figure 4 shown) to connect.

[0036] The controller 10 has a housing, which includes a...

Abstract

The invention provides a coded lock. The coded lock comprises a lockset and a controller; an unlocking assembly and a lock cylinder which is driven by the unlocking assembly are arranged inside a casing of the lockset; the unlocking assembly is provided with a rotary shaft; a rotary button which drives the rotary shaft to rotate is arranged on the controller; a motor and an over-rotate proof assembly are arranged inside the casing; the over-rotate proof assembly is provided with a rotary shaft which is driven by the motor; a first blocking plate is sleeved outside the rotary shaft; a portion of the first blocking plate is connected with the tail end of the lock cylinder in an abutting mode. The coded lock is capable of avoiding the motor rotary shaft from being fractured when the motor is overloaded and high in safety performance.

Description

technical field [0001] The invention relates to the field of locks, in particular to a combination lock with a motor. Background technique [0002] At present, a bank's ATM (Automated Teller Machine, self-service deposit and withdrawal machine) equipment cabinet is provided with a cash box, and the cabinet door of the cabinet is provided with a combination lock. The staff of the bank needs to open the combination lock before adding money to the cash box, and close the combination lock after the work of adding money is completed. [0003] Existing combination locks are usually composed of a lock and a controller. The controller is located on the cabinet door. The staff can operate the controller, such as input passwords and other verification information, and understand the working status of the combination lock through the display screen on the controller. . The lockset is installed on the inner side of the cabinet door for locking the cabinet door. In addition, the locks...
