Embodiment Construction

[0017] See attached picture. This embodiment consists of two parts, a lock box and a buckle box, the lock box part is installed on the door, and the buckle box part is installed on the door frame. Lock box comprises that lock box bottom 1 and lock box cover 9 are interlocked to form, and front end has lock box buckle plate 16, is combined as one with screw, has the partition wall 22 of band U-shaped breach in the lock box bottom. A shift block 5 is installed in the center of the lock box, which can be rotated by a handle (not shown). The front end fits with the rear end of the deadbolt 13, and the fitting part is provided with a washer 12, and a deadbolt spring 11 is also provided outside the neck of the deadbolt; The rubber ring 14 is engaged in the groove, and its surface is higher than the surface of the lock tongue after the engagement. Slider 7 has a first slider pad 3 up and down, one side is provided with shift block spring 15, one end of shift block spring 15 is agai...

Abstract

The invention discloses a door lock with a silencing effect, comprising a locking box, wherein the locking box is internally provided with a transmission mechanism and a locking tongue capable of doing axial and telescopic movement; the transmission mechanism comprises a sliding block; one side of the sliding block is provided with a sliding block spring; and one end of the sliding block spring is fixedly arranged on the sliding block by a second sliding block rubber pad, and the other end of the sliding block spring extends out of the sliding block, and the extending line is intersected with a fixed part in the locking box. The door lock disclosed by the invention has the advantages that on one hand, by use of cushioning parts such as the spring, the moving speed of the transmission mechanism is reduced; and on the other hand, since a great amount of nonmetallic silencing materials such as rubber rings and rubber pads are used, the friction and the collision among metal parts are furthest avoided, so that the noise caused by the door lock is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of household hardware, in particular to a door lock, especially a door lock with low noise and a mute effect. Background technique [0002] The door lock is a hardware installed on the door to maintain the privacy of the space. Its basic structure includes a deadbolt that can perform telescopic movement under the action of external force, and cooperates with the buckle box installed on the door frame to prevent the door from being locked. It is opened by accidents such as wind blowing. [0003] In some special occasions, such as wards, the requirements for quiet environment are very high, and the sound generated by opening and closing the door is enough to become a noise source; for the noise generated by the collision between the door and the door frame, people have found many solutions, such as using Damping hinges, and setting rubber strips at the junction of the door and the door frame, etc. After this...
