Elastic optical fiber jack type soundproof door bolt

Abstract

Optical fiber elastic socket noise-proof door insert, including matching door insert body and socket end, the door insert body is fixed on the door leaf, the door insert body is provided with an insert rod chute, and the insert rod is slidably connected in the insert rod chute , the inserting rod is threadedly connected with a handle, and the end of the inserting rod chute is provided with a top plate, which can limit the inserting rod by contacting the top plate with the handle; the jack end includes a jack seat for fixing on the door leaf, and the jack A jack is arranged on the seat, and an elastic reed is arranged on the inner wall of the jack. When the door plug is in the upward insertion state, since the elastic reed is set in the socket, the gap between the insertion rod and the socket is automatically eliminated under the elastic action of the elastic reed, even if there is wind disturbance, it will not be caused by the insertion rod and the socket. Noise is generated by the collision, and at the same time, because the elastic reed is compressible, it does not affect the convenient insertion and opening of the insertion rod, and the structure is simple and the cost is low.

Description

technical field [0001] The invention relates to a door insert, in particular to an optical fiber elastic socket anti-noise door insert, which is especially suitable for mother and child anti-theft doors and windows or fireproof doors and windows. Background technique [0002] The mother-in-law anti-theft doors and windows or fire doors and windows are composed of two door leaves or window leaves. Under normal circumstances, when using a door plug to lock the mother-in-law anti-theft door, an open or hidden plug is installed on one door leaf, and a socket is installed on the other door leaf. In order to facilitate installation and opening, the socket and plug of the door plug There will be a certain gap between the rods. This gap is convenient for installation and use, but it also brings problems. There will be noise caused by the collision of the door plug rod and the socket due to wind disturbance, and the wind will not stop and the noise will continue. , Disturbing people...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the noise problem caused by the collision between the insertion rod and the socket of the existing door plug due to wind disturbance, the invention provides an anti-noise door plug with an optical fiber elastic socket, which eliminates the gap between the insertion rod and the socket, and even if there is wind disturbance There will be no noise due to the collision between the insertion rod and the socket, and it will not affect the convenient insertion and opening of the insertion rod
