Abstract

The invention discloses a lock. The lock comprises a lock shell and a spring bolt mechanism; the lock shell is provided with a containing cavity and an opening communicating with the containing cavity; the spring bolt mechanism comprises a spring bolt and two lock hooks; the spring bolt is arranged on the containing cavity and moves to the locking position from the unlocking position via an opening in the front-and-back direction; when in the locking position, the spring bolt extends out of the containing cavity; the two lock hooks are arranged on the spring bolt in a bilateral symmetry mode;each look hook is provided with a barb; and the two lock hooks are configured that when the spring bolt moves towards the unlocking position, the two barbs shrink to be hidden into the left side faceand the right side face of the spring bolt and when the spring bolt moves towards the locking position, the two barbs extend out of the left side face and the right side face of the spring bolt separately. According to the lock provided by the embodiment of the invention, the look hooks can prevent the spring bolt to retract, and therefore the lock anti-theft performance is improved.

Description

technical field [0001] The invention relates to a lock. Background technique [0002] The lock is used as a kind of anti-theft tool to lock the locked object (such as the door body) to prevent others from entering the locked object and being opened. [0003] The lockset in the related art includes a lock case, a dead bolt and a driving member for driving the dead bolt. The lock case is provided with an opening, and the driving member drives the dead bolt to protrude or retract from the opening, thereby realizing locking or unlocking. In the lockset of this structure, the deadbolt is usually a square block or a wedge-shaped block, which is easily unlocked by violent or other means during use. Therefore, its anti-theft performance needs to be further improved. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the object of the present invention is to propose a l...
