Mortise and tenon spring lock cylinder

Abstract

The invention relates to a mortise and tenon type reverse cylinder lock core. Key holes are formed in the bottom of a front lock cylinder cover, grooves a are machined in the inner side wall, grooves b are formed in the bottoms of the grooves a, a key is arranged in the key holes, and cylinders are installed in the grooves a; a front inner lock core pad is fixedly installed in the center of the bottom in the front lock cylinder cover and in a cylindrical geometrical shape, through grooves e are formed in the cylindrical outer surface, an inner lock core body is placed on the front lock core pad, a lock core shaft is machined in the center of a disc of the bottom of the lock core body, the tail end of the lock core shaft is machined into a circular cylinder with the diameter smaller than that of the lock core shaft, grooves are machined in the circular cylinder, through grooves f are machined in the side face of the disc at the bottom of the inner lock core body, and a rear inner lock core pad and a rear lock core cover are sequentially installed on the lock core shaft of the inner lock core body; the rear inner lock core pad is fixedly installed on the rear lock core cover, through grooves g are machined inn the side face of the rear inner lock core pad, grooves c are formed in the inner side wall of the rear lock core cover, and grooves d are machined in the bottoms of the grooves c; spring grooves are formed by the grooves b and the grooves d and provided with springs, and cylinder grooves are formed by the grooves a and the grooves c.

Description

technical field [0001] The invention belongs to the technical field of locks, and in particular relates to a mortise and tenon type rebound lock cylinder. Background technique [0002] In 1848, the American Yale Linus invented the pin lock with a cylindrical pin. The pin lock is also called pin ball lock, bead lock, bead lock, bolt lock or pin lock. It is the most common lock structure. The principle is to use multiple cylindrical parts of different heights (called lock springs, pins or beads) to lock the lock cylinder. When the correct key is put in, each lock spring is pushed to the same height, and the lock cylinder is released. At present, this structure is widely used in the world. The structure of modern pin locks has new developments, and there are two-way, three-way, four-way pins, mother pins and other structures, as well as flat, double-sided, multi-sided, double-row double-sided, multi-row multi-sided pin pin structures and combined pin pin structures. Thereby t...

Problems solved by technology

However, the disadvantages are becoming more and more obvious. There are three main aspects: the end of the pin is exposed and the working stroke is short. Accessible to the lock cylinder, it is easy to cause mutual opening of keys and unequal key teeth, etc.; the key can be freely configured, and the key matching process is simple. With a key mold of a tumbler lock, the door can be easily opened within ten seconds with tin foil installed; Unlock the lock violently, twist off the pin, it is easy to open the lock
