[0002] Cash boxes are boxes that have certain anti-robbery, anti-theft and anti-destruction functions and are used to store and transport valuables such as cash and precious metals. Electronic anti-theft locks are locks that electronically identify and process relevant information and control the actuator to open and close and reach the specified security level.

[0003] Traditional cash boxes mostly use mechanical padlocks, which have a lock row on the outside of the box, and are convenient for opening the lid by holding the lock row. Smart cash boxes usually have electronic anti-theft locks installed inside the box, and there is no lock row on the outside, so there will be no obvious relative displacement between the box cover and the bottom box before and after the electric lock is opened.

[0004] However, the existing cash withdrawal boxes with electric locks are subject to the following problems: 1. After the electric lock of the existing cash box is opened, it is difficult to judge whether it is opened successfully from the appearance, and it is not convenient to open it manually. It is not as intuitive and convenient as the mechanical padlock; 2. There are no multiple verification methods after the locking is completed. When a single verification method has problems, it is difficult for the operator to obtain the correct status of the current cash box in a timely and effective manner, which is prone to false locks and virtual locks.

[0015] Compared with the prior art, the present application is provided with a rebound prompt mechanism. When the box cover is buckled to the bottom box, the elastic member of the rebound prompt mechanism continuously applies elastic force to the box cover to prevent the buckling action. Without the locking of the lock pin and the lock beam, and without external pressure, the box cover cannot be buckled on the bottom box by its own gravity. The operator can easily observe the state of the box cover with the naked eye, thereby making a preliminary judgment on the locking state of the cash withdrawal box. The rebound prompt mechanism of the present application is also provided with an in-place switch. Only when the box cover is completely buckled on the bottom box, the in-place switch will output a locking signal. Therefore, the present application can make a comprehensive judgment on the locking status of the cash withdrawal box by observing the status of the box cover and the bottom box, the type of output signal of the in-place switch displayed by the signal visualization module, and the status of the current action instruction issued by the locking switch.
