Abstract

The invention discloses a mechanical unlocking and counter locking mechanism. The mechanical unlocking and counter locking mechanism comprises a lock box, a latch bolt assembly, a main bolt assembly, a shifting fork assembly, a shifting piece assembly, a counter locking piece and a first push plate, wherein the lock box comprises a side plate and a bottom plate, and the latch bolt assembly comprises a latch bolt and a latch bolt connecting piece; the main bolt assembly comprises a main bolt and a main bolt push plate; the shifting fork assembly comprises a shifting fork body and a shifting fork push rod; the shifting piece assembly comprises a shifting piece body, and the shifting piece body extends in the direction of the latch bolt connecting piece to form a shifting rod used for driving the latch bolt connecting piece to move; and the first push plate is used for pushing the counter locking piece and the shifting piece body to rotate in one direction. When the first push plate pushes the counter locking piece and the shifting piece body to rotate in one direction, the counter locking piece drives the main bolt assembly to move towards the inner side of the lock box through the shifting fork assembly, and therefore main bolt unlocking is achieved; and the shifting piece body drives the latch bolt assembly to move towards the inner side of the lock box through the shifting rod, and therefore latch bolt unlocking is achieved. The mechanical unlocking and counter locking mechanism has the advantages that the first push plate can push the counter locking piece and the shifting piece body to rotate at a large angle only by a very small stroke, and unlocking is convenient.

Description

technical field [0001] The invention relates to the technical field of electronic locks, in particular to a mechanical unlocking and anti-locking mechanism. Background technique [0002] The electronic lock can be mechanically unlocked or locked by manually rotating the key. During the unlocking or locking process, the key is inserted into the electronic lock, and the key is rotated. The key drives the fork to rotate, and the fork drives the main tongue and oblique tongue to unlock or lock. During the rotation of the key, a large-angle rotation is required to drive the fork to rotate at a large angle, so unlocking or anti-locking is time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a mechanical unlocking and anti-locking mechanism. [0004] A kind of technical scheme of the present invention: [0005] A mechanical unlocking and anti-locking mechanism, compr...
