Improved side lock

Abstract

The invention relates to a side lock, in particular to an improved side lock which comprises a shell. A spring bolt used for locking in a matched manner is arranged in the shell, and the spring bolt is rotationally connected into the shell and forms a rotating surface; a push block which drives the spring bolt to rotate and is perpendicular to the rotating surface in the axial direction is also included, and the push block is in sliding fit with the shell in the radial direction; unlocking and locking of the spring bolt are achieved through reciprocating motion of the push block, the spring bolt adopts a plane rotating manner, and the matched spring bolt hooks a lock hook of a box body in a shape similar to a crescent, so that the matched stress surface of the spring bolt and the lock hookis improved, the structural stability of a lock body is greatly improved, and the lock body becomes firmer; the size of the improved lock body is obviously smaller than that of a traditional lock body, so that the production cost is reduced; and in addition, a locking mechanism for preventing the box body from being opened accidentally is additionally arranged, the safety effect is achieved, thepracticability of the lock body is greatly improved, and the improved side lock has the advantages of being simple in structure, convenient to machine, easy to assemble and high in practicability.

Description

technical field [0001] The invention relates to a side lock, in particular to an improved side lock. Background technique [0002] Side locks are generally symmetrically distributed on both sides of the combination box, and a central control lock is set in the middle. The security system of the box is set up by the password of the central control lock or the opening and closing system of the key, and the opening and closing of the box is controlled by the side lock. , The implication is that to open the combination box, you must first open the central control lock, and then open the side locks to fully open the box. [0003] At present, the side locks on the market all adopt a seesaw-type pressing structure, such as the patent whose publication number is "CN2240576Y" and the patent name is "suitcase side lock". The arm of force will be increased to achieve the purpose of saving labor, which will bring the lock body into a dilemma where it is difficult to reduce the size. Th...

Problems solved by technology

[0003] At present, the side locks on the market all adopt a seesaw-type pressing structure, such as the patent whose publication number is "CN2240576Y" and the patent name is "suitcase side lock". The force arm will be increased to achieve the purpose of saving labor, which will bring the lock body into a dilemma where the size is difficult to reduce. Therefore, how to create a side lock with a new structure is the problem we need to solve now.
