Description

password

technical field

The utility model relates to a password lock.

Background technique

Combination locks are widely used as security locks for bags. At present, the existing coded locks mainly include the coded lock function and the key lock function. Under normal use, the user only needs to open or close the coded lock function. , it can be opened through the key lock function.

At present, the functions of the existing key lock mainly include the lock body, the lock cylinder, the unlocking part and the buttons on both sides of the lock body. By pressing the button, the lock cylinder drives the unlocking part to make the locking part realize the purpose of unlocking. The buttons on both sides are easy to set. Damage is caused during the pressing process, and the stability is poor. The linkage of the buttons on both sides through the same spring will easily cause the buttons on both sides to fail to work at the same time.

By adopting the above technical solution, in the locked state, the block abuts against the groove formed by the hook part of the lock, generating a force that pushes the lock inward, making it more tightly assembled and preventing the lock from being broken. Shaking or swaying, the side of the block close to the locking piece is rounded to reduce scratches on the lock and increase the service life.

Further, the bent section of the lock buckle is provided with a guiding slope, the button includes a supporting piece supported by the extending section, and the supporting piece is provided with a guiding slope on a side facing the outside of the housing.

By adopting the above technical scheme, the guide slope facilitates the release and installation of the lock. The guide slope on the support member cooperates with the installation hole to play the role of guide installation. damage to internal components.

Further, the housing is provided with a spring corresponding to the button to reset the button upwards, one end of the spring is connected to the housing, and the other end is connected to the button.

By adopting the above technical solution, the spring assists the reset of the button, prevents the button from being located in the housing and hinders the reset of the interfering block of the locking member, the spring connects the housing and the button to make the installation stable, and the spring can be driven to store energy when the button is pressed down .

Further, the housing is fixedly connected with a lock hook through two bolts.

By adopting the above technical solution, the housing has lock hooks through two latches, and the two lock hooks ensure the connection strength and connection stability, and increase the service life.

Further, a return spring is arranged between the lock hook and the housing, and there are two return springs, which are respectively arranged on both sides of the lock hook.

By adopting the above technical solution, the two springs can stabilize the stress of the locking hook, and when one of the springs is damaged, the other spring can also drive the locking hook to reset, thereby improving fault tolerance and service life.

Further, the housing is provided with a spring installation hole for installing a return spring, and the spring installation hole is arranged symmetrically corresponding to the position of the locking hook.

By adopting the above technical solution, the spring installation hole facilitates the installation of the spring.
