Description

technical field [0001] The invention belongs to the technical field of safety facilities of a cash transport vehicle, and in particular relates to a locking device for a safe door of a cash transport vehicle. Background technique [0002] A common safe door lock device is roughly composed of a combination lock, a mechanical lock, and a locking mechanism. The combination lock and the mechanical lock control the locking mechanism deadbolt.

The existing shortcoming of this safe door locking device is: mechanical lock d...

AI Technical Summary

Problems solved by technology

The disadvantage of this safe door locking device is that the mechanical lock does not have the function of automatic locking. The automatic locking function mentioned here means that when the cabinet door is closed, it can be locked without manipulating the mechanical lock.

Therefore, the safe door locking device in the prior art is not suitable for some special occasions such as on the safe door of the cash transport vehicle, because when the cash transport vehicle arrives at the destination and is in the process of taking out or putting in coins or documents etc. in the safe During the process, once encountering unexpected situations such as hijacking, robbery, etc., the first reaction is to close the door of the safe, and the door of the safe must be locked in the fastest time.
