Spring bolt mechanism and lock

Abstract

The invention relates to a spring bolt mechanism and a lock. The spring bolt mechanism comprises a spring bolt, a movable plate and an elastic piece; the spring bolt can move in a telescopic mode, anda limiting piece is arranged on the spring bolt; the movable plate is provided with a sliding groove, and the sliding groove comprises a first groove section which is obliquely arranged relative to the movable direction of the spring bolt; the limiting piece is arranged in the sliding groove in a penetrating mode, so that linkage of the spring bolt and the movable plate is achieved; a guide inclined plane parallel to the first groove section or forming a small included angle with the first groove section is arranged on one side surface of the movable plate; one end of the elastic piece is connected with the spring bolt, and the other end of the elastic piece abuts against the side face, provided with the guide inclined plane, of the movable plate; and when the movable plate moves to pushthe spring bolt to move in a telescopic mode, the limiting piece moves in the first groove section, and the end, abutting against the side face of the movable plate, of the elastic piece moves on theguide inclined plane. In the whole locking and unlocking process, the elastic piece does not deform or deforms little, so that when the spring bolt contracts for unlocking, only the friction force between the spring bolt and a lock hole needs to be overcome, unlocking can be achieved without large torsion, and labor is saved during unlocking.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a latch mechanism and a lock. Background technique [0002] With the continuous advancement of technology, various forms of locks have appeared in life, including combination locks and fingerprint locks. Among them, a combination lock is an electronic product that controls the operation of a circuit or a chip (access control system) through the input of a password, thereby controlling the closing of a mechanical switch and completing the task of unlocking and locking. There are many types of it, including simple circuit products and cost-effective products based on chips. Now the widely used electronic combination lock is based on the chip and realized by programming. Electronic locks In the field of security technology prevention, electronic combination locks with anti-theft alarm function replace traditional mechanical combination locks, overcoming the shortcomings of mechanica...
