Magnetic silent lock body

Abstract

The invention relates to a lock part of a door lock and provides a magnetic silent lock. According to the scheme, the magnetic silent lock comprises a lock box, wherein a spring bolt, a manual shifter, a locking mechanism and a cross shifter are respectively embedded in the lock box; the lock box consists of a substrate, a bottom box and a box cover; the spring bolt is made of a wear-resistant plastic material; a magnet embedding groove is formed in the spring bolt, and a magnet is embedded in the magnet embedding groove; a shifting cutter is arranged at one end of the manual shifter and can shift a locking arm on the spring bolt, so that the spring bolt retracts back into the lock box so as to unlock the lock; the locking mechanism consists of a positioning plate, a spring bolt plate and a spring bolt shifting piece; an open positioning toothed groove and a counter lock positioning toothed groove are formed in the spring bolt plate and are respectively clamped with positioning lugs on the positioning plate, so that open positioning and counter lock positioning are realized; the shifting piece on the cross shifter and a shifting groove in the spring bolt plate are matched, so that the spring bolt plate can be transversely shifted. According to the attraction of a magnet in the spring bolt, the spring bolt can automatically extend out in the process of closing the door, and noise of closing the door is reduced. Meanwhile, the magnetic silent lock has the counter lock and unlocking functions and a windproof effect.

Description

technical field [0001] The invention relates to a hardware door lock accessory, in particular to a lock body part of the door lock. Background technique [0002] At present, the lock body that is locked by spring force is widely used in the market. When the lock tongue is in a free state, it stretches out of the lock box by virtue of the spring force. When the door is closed, friction and collision will occur between the lock tongue and the door frame, and the lock tongue will retract. Then pop it out and insert it into the buckle box. This kind of lock body will make a sound due to the collision between the deadbolt and the door frame when the door is closed, and the sound will also be made when the deadbolt is inserted into the buckle box under the action of elastic force. When it is blown by the wind, it makes a collision noise, so it cannot adapt to people's requirements for silent door locks. Contents of the invention [0003] The purpose of the present invention is...
