Mute magnetic lock body

Abstract

The invention provides a mute magnetic lock body which comprises a lock body lining plate assembly, a magnetic tongue assembly, a square tongue assembly, a square core shifting assembly, a torsional spring, a buckle box assembly, a lock body box bottom assembly and a box cover. The magnetic tongue assembly is internally provided with a magnetic tongue magnet, and the box bottom inside the box bottom assembly and the square core shifting assembly are each made of an easily-magnetized material; when external force acting does not exist, the magnet generates attractive force, so that a magnetic tongue keeps in a withdrawing state all the time; the magnetic lock body buckle box assembly is provided with a buckle box magnet, and when the buckle box magnet makes contact with the magnetic tonguemagnet in the magnetic tongue assembly during door closing, N and S poles are opposite, so that a door can be locked; and after door opening, attractive force between the magnetic tongue magnet and the box bottom as well as between the magnetic tongue magnet and the square core shifting assembly enables the magnetic tongue to be withdrawn and then keep flush with a lining plate. Through cooperation of the square tongue assembly and the magnetic tongue, when the magnetic tongue stretches out, a square tongue can be shifted, after the square tongue stretches out, the magnetic tongue is locked, and a handle idles; and the mute magnetic lock body is ingenious in conception, compact in structure and reliable in function.

Description

Technical field: [0001] The invention relates to the field of door locks for construction and home use, in particular to an indoor magnetic lock body, especially a silent magnetic lock body with low noise. Background technique: [0002] The mechanical lock body will wear to different degrees after long-term use, such as unsmooth unlocking, noise, and rust. Clothes are often caught when walking, especially when wearing a sweater in winter. At the same time, when children are running or playing, it is easy to cause bruises. Aiming at the above-mentioned problems existing in the existing lock body, related technologies have appeared on the market The scheme overcomes related defects, and the most practical one at present is the magnetic lock body. [0003] At present, magnetic locks generally have the functions of anti-locking and unlocking. In order to realize the functions of anti-locking and unlocking, the magnetic locks in the prior art often have a complicated structure, ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the structure of the magnetic lock body is complex, the production cost is high, and the use noise is large. To provide a magnetic lock body with a simple structure, which can realize anti-locking and unlocking functions, and good stability
