Lock body inclined tongue buffer structure

Abstract

The invention provides a lock body inclined tongue buffer structure. The structure comprises a lock body outer lining plate, an inclined tongue module, a damper, a connecting rod, an inclined tongue shifting module, a transmission piece, a square tongue mechanism, a box cover and a lock body box bottom module; the inclined tongue module comprises an inclined tongue, a friction tongue, a pull rod, a spring, a limiting silent ring and a slide block; and the lock body box bottom module comprises a lock body lining plate, a square tongue silent block, an inclined tongue silent block, a box bottom, a stud, a guide column, a positioning plate, a spring, a fastening nail and a damper. The structure adopts one or more of silent plastic materials such as nylon, TPE elastic plastic and ABS for manufacturing the parts so as to replace metal parts, or adopts a method of separating the metal parts by silent plastic materials to reduce the noise generated by friction. Meanwhile, the buffer function of the damper is matched to reduce the noise generated by mutual collision among all parts in working of a lock body.

Description

Technical field: [0001] The invention relates to the field of door locks for building and home use, in particular to a lock body, especially a mute lock body with low noise. Background technique: [0002] At present, the components of the door locks used in the home furnishing field are usually made of metal materials, and when the door is opened and closed, noise will be emitted due to impact or friction between the various parts. With the improvement of people's consumption level, it is hoped to reduce such noise as much as possible in office or home. Many inventors have proposed corresponding solutions from different technical perspectives. A common solution is to start from the lock tongue that is most prone to impact, and directly slow down the impact of the lock tongue or improve the parts in contact with it, which has a certain positive effect in reducing the noise generated when closing the door. But the effect is not very obvious, for example: install a rubber rin...

AI Technical Summary

Problems solved by technology

The problem is that the rubber ring is easy to age, and it is glued to the pull rod, so that the latch tongue cannot be stretched out (or retracted)

Or in colder environments the damping oil can condense, increasing the resistance and making the latch tongue sluggish when extending (or retracting)
