Description

Lock body rolling lock tongue

Technical Field

The utility model belongs to the technical field of the spring bolt device, concretely relates to lock body roll spring bolt.

Background

The lock body of big lock and bedroom lock that each family used at present all is the inclined plane spring bolt, this kind of inclined plane spring bolt all is this inclined plane spring bolt and produces sliding friction between the fender of installing on the door frame when closing the door, the new lock sliding friction power of just beginning to install is less relatively, the lapse of time and the increase of inclined plane spring bolt number of times of use at any time, the frictional force between the fender on inclined plane spring bolt and the door frame can be bigger and bigger, produce certain influence even to closing the door, the spring bolt withdrawal is locked when people exert oneself the undersize, even you can not lock with big strength at any time no matter how much sometimes, the noise is still big, not only influence people's mood, the life of spring bolt has still been shortened, increase the cost of changing or maintaining the lock, waste time and energy.

After long-time research to overcome the technical problems, the applicant considers that the rolling lock tongue of the lock body disclosed herein has necessary practical significance from the practical point of view.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a lock body roll spring bolt to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a lock body rolling bolt is characterized by comprising: the bolt comprises a bolt body (1), a first bearing groove (5) and a second bearing groove (6) are respectively arranged on one side of an inclined plane of the bolt body (1) from top to bottom, a first rolling bearing (3) and a second rolling bearing (4) are respectively arranged in the first bearing groove (5) and the second bearing groove (6), the bolt body (1) is longitudinally provided with a screw hole (7), inner threads (7-1) are arranged at one end of the bottom of the screw hole (7), a rolling screw (2) is arranged in the screw hole (7), the rolling screw (2) is arranged in central holes of the first rolling bearing (3) and the second rolling bearing (4), outer threads are arranged at the lower end of the rolling screw (2), are matched with the inner threads (7-1), and a bolt tail rod (8) is arranged on the opposite plane of the inclined plane of the bolt body (1).

Preferably, the outer circular surfaces of the first rolling bearing (3) and the second rolling bearing (4) are 0.1-0.3mm higher than the inclined surface of the bolt body (1).

Compared with the prior art, the utility model provides a lock body roll spring bolt possesses following beneficial effect:

the sliding friction between the original lock tongue and the door shield is changed into the rolling friction between the outer circular surface of the first rolling bearing (3) and the second rolling bearing (4) and the door shield, the friction force is relatively small, the door is easily locked, the noise is low, the door lock is comfortable, the service life of the door lock is prolonged, the maintenance cost is saved, and the door lock is replaced, and time and labor are saved.
