Description

Auxiliary lock collar

The utility model relates to an auxiliary lock, in particular to an auxiliary lock collar arranged between the auxiliary lock seat and the bright plate.

As people pay more attention to home safety, the development of door locks has developed from a single lock to the combination of multiple locks, and the most common is the application of horn locks with auxiliary locks. Therefore, with the generalization of applications, the structure of auxiliary locks Research and development has tended to be multi-directional, from the interlocking design between the auxiliary lock bolt and the horn lock, to the design that the auxiliary lock bolt can be applied to different specifications of horn locks, which has made the auxiliary lock structure more sophisticated. However, in addition to the functions such as convenient operation, the most important thing in the design of a lock is the anti-theft function. If the anti-theft function cannot meet the requirements of consumers, even if it has other peripheral functions, it is still not designed. Perfect structure.

Therefore, as far as the anti-theft function is concerned, the general auxiliary lock is composed of several parts, namely the inner and outer lock base, the lock core and the lock bolt. Among them, the most vulnerable parts are the lock core and the lock base. The industry has developed quite a lot of excellent structures, such as the lock core of the mother and child pins, the lock core of the H channel, etc., so the anti-theft function has been significantly improved. However, the collar of the lock seat is currently There is no more strengthened design, which has become the key point of destruction when criminals cannot successfully destroy the lock core. The structure of the existing lock seat shown in Figure 7 is explained below: Please refer to Figure 7.
