Noiseless lock with magnets

Abstract

The invention relates to hardware door lock accessories, and provides a noiseless lock with magnets. The noiseless lock with the magnets is provided with a box bottom assembly, a box cover, a rotation block, a lever-handle sleeve, a tension spring, a driving block, a reset spring, a lock tongue assembly and a cover buckling assembly. The front end of the box bottom assembly is provided with a lock tongue hole, and the inner portion of the box bottom assembly is provided with a rotation piece pivot, a lever-handle sleeve embedding hole, a lock tongue guide groove, a driving guide groove and a fixed tension spring embedded column. The lock tongue magnet is arranged in a lock tongue and the box buckling magnet is arranged in the box buckling assembly. The lock tongue assembly is embedded into the lock tongue guide groove, the driving block is embedded into the driving guide groove, the lever-handle sleeve is embedded into the lever-handle sleeve embedding hole and the rotation block is embedded on the rotation pivot through a pivoting hole in the middle of the rotation block. The noiseless lock realizes the function that under the attraction effect of the magnets, locking is realized as the lock tongue stretches out directly, achieves the effect that noise generated due to the fact that collision and friction are generated between the inclined lock tongue and the cover buckling assembly when a door is closed is eliminated and achieves a better silencing effect.

Description

technical field [0001] The invention relates to a hardware door lock accessory, in particular to a lock body part with a magnet for the door lock. Background technique [0002] Most of the known magnetic locks at present utilize magnetism to realize the opening and closing of the door lock, some of which use electromagnets, and some of which use permanent magnets. For example, in the permanent magnetic lock disclosed in CN101525959B, a magnetic core made of rare earth permanent magnetic material is arranged in the lock body, and the direction of the magnetic force line of the magnetic core is changed by rotation to realize the adsorption and release of the lock body. Whether using electromagnets or permanent magnets, the currently disclosed magnetic locks will emit collision sounds when they are attracted and released. To eliminate such sounds, the contact surface of the deadbolt is usually changed to plastic material. The adoption of this method is still unavoidable that t...

Problems solved by technology

The use of this method is still unavoidable. The contact between the lock tongue and the gusset plate, that is, the collision and friction sound generated by the lock tongue and the gusset plate cannot be eliminated.
