Technical Field

The utility model relates to a lock field, in particular to children's lock.

Background

In order to prevent children from entering dangerous areas safely at home, parents often use a child door lock which is convenient to open and close, the child safety can be guaranteed for one purpose, and the daily repeated use is not influenced due to the fact that the child door lock is convenient to operate for two purposes. However, the existing children door lock convenient to operate uses the combination of the bolt and the spring piece to complete the locking and unlocking operation, and the structure easily scrapes the surface of the inside of the door lock, so that the inside of the door lock is easy to rust, and the service life of the locking and unlocking structure is short under daily repeated use.

The technical problem to be solved by the application is as follows: the problem of children's lock open the short-lived of shutting structure is solved.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide a children door lock capable of prolonging the service life of an unlocking lock.

The utility model discloses the technical scheme who adopts does: the utility model provides an improve children's lock of opening and shutting life-span, which comprises a base and a rotating shaft, the pivot is at base normal running fit, the base is equipped with fixed connection's mold insert seat with it, a mold insert seat pot head is established on pivot portion outer wall, the other end is equipped with the bolt spout, the bolt spout is equipped with rather than sliding connection's bolt, the pivot bottom is equipped with locking groove, bolt spout and locking groove intercommunication, bolt one end is equipped with the locking lug with locking groove shape complex, the bolt is equipped with the fixed orifices, from the top down is equipped with ball and compression spring in the fixed orifices, bolt spout top is equipped with the apron, the apron is equipped with the solid locked groove with ball shape complex arc, when locking groove is connected with the locking lug screens, the ball is connected with the solid locked groove screens of arc.

The bolt slides in the bolt spout through the ball, when locking groove and locking lug do not carry out the screens and be connected, compression spring is in compression state, when locking groove and locking lug carry out the screens and be connected, compression spring bounces out, the ball is connected with the solid keyway screens of arc, in order to be connected between fixed locking groove and the locking lug, because the ball is rolling motion, reduce the condition on abrasion apron surface, the elasticity life-span of spring is than the spring leaf longe-lived, can guarantee to open and close the life-span of keying structure.

In some embodiments, the insert seat is embedded in the base, and the total height of the pin and the cover plate is lower than the height of the base. The whole base of inlaying of mold insert seat for lock inner structure is compacter, and the lock is whole more exquisite.

In some embodiments, a handle is fixedly connected to the rotating shaft.
