Abstract

The invention discloses a cabinet door locking device with an emergency opening function, comprising a lockset and a cabinet door locking / unlocking device, wherein the lockset comprises a lock body and a locking dog locked / unlocked with the lock body; the cabinet door locking / unlocking device comprises an external locking / unlocking device and an emergency unlocking device; the external locking / unlocking device comprises an external handle, a linking arm, a linking plate, a latch fixed plate and a lockset elastic pre-locking device; a rotating shaft of the external handle, the linking arm, the linking plate, the latch fixed plate and the lockset elastic pre-locking device are connected in a linking manner; the emergency unlocking device comprises a circular lining plate, a square linking plate, an emergency rotating shaft, a rotating shaft driving device and a connecting tension spring in a linking manner; and the rotating shaft driving device, the emergency rotating shaft, the square linking plate, the circular linking plate, the connecting tension spring and the lockset elastic pre-closing device are connected in a linking manner. Therefore, with the scheme, the emergency opening of the cabinet door can be realized by using the emergency unlocking device and the phenomenon that the cabinet door cannot be opened due to the self-locking of the lockset can be avoided.

Description

technical field [0001] The invention relates to a lock, in particular to a cabinet door locking device with emergency opening. Background technique [0002] At present, most safe doors only have a single lock, which is opened or locked on the outside of the cabinet door. Therefore, when the lock is self-locking and cannot be opened, it will cause inconvenience to the user. Therefore, a lock that is currently commonly used is required. (such as mechanical locks or electronic locks, etc.) are used in conjunction with emergency opening devices equipped with common locks for emergency opening, so as to avoid the phenomenon that the cabinet door cannot be opened when it is locked. [0003] In addition, the application of safes is more and more extensive, and its anti-theft effect is more and more remarkable. However, commonly used safes can only be opened / closed from the outside, and generally do not have the function of opening from the inside of the safe. Therefore, when the ...
