Problems solved by technology

[0003] Existing room door locks have the following deficiencies in terms of structure and silence: 1. The rebound of the traditional door lock body deadbolt relies on the thrust of its internal spring. It is relatively large, and the deadbolt has no buffer during the rebound process, and it will generate a lot of noise when it rebounds instantaneously; 2. The deadbolt of the traditional door lock body is installed on the door, and the door is usually facing into the room. When the door is opened, the inclined end face of the dead bolt is set from the outside to the inside of the door. When the door is closed, the sound of the dead bolt hitting the door frame will be transmitted along the inclined end face of the dead bolt to the inside of the door, resulting in a large noise; 3. The traditional lock body usually requires Rotate the door handle about 45° to pull the bolt back and open the door, which is laborious to use

Example Embodiment

[0032] Example 1: A mute double magnetic lock body for the door, such as Figure 1-Figure 9 As shown, it includes a lock tongue at the fixed end of the door frame and a door lock body. The lock tongue at the fixed end of the door frame includes a lock tongue fixing baffle 1, a lock tongue housing 2, a tension spring 6, a lock tongue 9 and a cylindrical magnet I10. The bolt shell is a hollow cylindrical structure with an opening. The bolt 9 is a cylinder. The open end of the bolt shell is defined as the front end and the other end is the tail end. The bolt is installed in the bolt shell, and the tension spring 6 is connected. Between the bolt and the end of the bolt shell, there is a spring fixing groove at the end of the bolt. One end of the tension spring is in contact with the end of the bolt shell, and the other end is fixed in the spring fixing groove of the bolt with a fixing screw 7. There is a gap between the outer wall of the bolt and the inner wall of the side of the bolt

Abstract

The invention relates to a silent double-magnetic lock body for a door. The silent double-magnetic lock body for the door comprises a door frame fixing end spring bolt and a door lock body, wherein the door frame fixing end spring bolt comprises a spring bolt fixing baffle plate, a spring bolt shell, a tension spring, a spring bolt and a magnet I; the door lock body comprises a lock body baffle plate, a lock body shell, a swinging lock block and a magnet II; when at a door closing state, the front end of the spring bolt is located in the lock body shell, the tension spring is at a natural state, the swinging lock block is located in a through slot, and a gap exists between the spring bolt and the swinging lock block at the moment; and when at a door opening state, the swinging lock block is located in the lock body shell, the magnet I on the spring bolt and the magnet II on the swinging lock block produce a repelling force, the spring bolt is located in the spring bolt shell, and the tension spring is at a contraction state. The silent double-magnetic lock body for the door provided by the invention is designed by adopting a principle that the polarities of the two magnets repel toeach other, and the spring bolt adopts buffer delay propulsion, so that the noise produced in the door opening and closing process is reduced.
