Electronic key storage box

Abstract

The invention discloses an electronic key storage box which comprises a shell and a cavity formed inside the shell and used for storage. A front panel for password input is arranged at the front faceof the shell, and a lock mechanism and a control circuit are arranged on the inner side of the front panel. The electronic key storage box is characterized in that the lock mechanism is an electroniclock and comprises a driving circuit, a lock tongue piece and an installing assembly connected with the lock tongue piece, and the driving circuit is used for receiving unlocking information of the control circuit and controlling the effect on the lock tongue piece; the installing assembly comprises a lock support, a rotating shaft located on the lock support and a lock hook spring arranged on therotating shaft, a lock hook groove is formed in the lock tongue piece, and the lock hook groove is matched with a locking pin on the shell; the lock tongue piece is matched with the lock hook springthrough the driving circuit, so that the lock hook groove and the locking pin form the engaged state or the separated state. By adopting the mode of the electronic lock, a key box can be automaticallyopened, use is more convenient, the lock structure is safer, and error starting is avoided.

Description

technical field [0001] The invention relates to a key box, in particular to an electronic key storage box. Background technique [0002] A key box, as the name implies, is a box used to store keys.

More importantly, the locks currently used in this type of key box are all locked by the cooperation of the lock tongue and the lock hole. The lock tongue uses the elastic force of a single spring as the locking force to support the closing of the lock tongue and the lock hole. After the vibration, it is inevitable that there will be a problem of false opening, and the safety is poor
