Background

The door stopper is a device for fixing the door when the door is opened to the maximum position and preventing the door from being accidentally blown to be closed, the existing household door stoppers mostly adopt a wall-mounted permanent magnet door stopper, when the door is opened and fixed at the maximum position, the collision sound is large, the life quality is influenced slightly, and the upstairs, downstairs and neighborhood relations are influenced heavily. Meanwhile, with the increase of the collision times, the damage risk of the door stopper is correspondingly increased. For example, a "buffering door stopper" disclosed in the chinese patent document, whose publication number "CN 205047007U" is provided with a door stopper ball, a buffering rubber ring, a door stopper pull rod and a sleeve component, wherein the door stopper ball is embedded and fixed at one end of the door stopper pull rod, and the other end of the door stopper pull rod is inserted into the sleeve component; the sleeve component consists of a sleeve, a damping buffer component and an elastic buffer component, wherein the damping buffer component and the elastic buffer component are arranged in the sleeve, the damping buffer component is arranged at the left end of the sleeve, and the elastic buffer component is arranged at the right end of the sleeve. When the door stopper ball is pressed by external force, the door stopper pull rod retracts into the sleeve, when no external force is applied, the door stopper pull rod extends out of the sleeve, and the door stopper pull rod is subjected to the resistance action of the damping buffer component and the elastic buffer component in the stretching process, so that the moving speed of the door stopper pull rod is reduced. Although the device realizes the partial buffer of the collision of the door stopper through the spring, when the door is closed, no force buffer device exists between the suction head and the base, the suction head and the base of the door stopper are still in rigid contact, and the collision sound is still relatively large when the suction head and the base of the door stopper are in contact. In order to improve the defects of the door stopper, the invention provides a mute door stopper.

The silence door-inhale including setting up the magnet subassembly on the door leaf and setting up the door-inhale base on the wall body, the buffering subassembly cover is located on the door-inhale base and is used for realizing the slow-down buffering when the door leaf collides the wall body to fall the mechanism through the two-stage formula and will collide the noise with the minimum, the direct striking of magnet subassembly and door-inhale base can be avoided in this kind of design, effectively improves the silence effect.

Preferably, the base is provided with a central body, the central body is of a columnar structure, the double-stage noise reduction mechanism comprises a damping piece and a buffer sleeve, and the damping piece and the buffer sleeve are sequentially sleeved on the central body along the direction of the central body far away from the extension direction of the base. The central body on the base is used as a connection structure of the base and the magnet assembly when the door stopper works, and is used as a bearing piece of the double-stage noise reduction mechanism, so that the damping piece and the buffer sleeve can normally run between the base and the magnet assembly.

Preferably, the buffer sleeve is of an open cavity structure, a sleeving hole which is sleeved with the central body in a sliding mode is formed in the bottom of the cavity of the buffer sleeve, and the cavity of the buffer sleeve is sleeved with the magnet assembly in a sliding mode. The buffer sleeve is a double-point contact part which is sleeved with the central body in a sliding mode through the sleeving hole, and the magnet assembly is sleeved with the inner wall of the cavity in a sliding mode. The design enables the buffer sleeve to replace a door suction base to become a transition part which directly collides with the magnet assembly, and when the buffer sleeve collides with the magnet assembly, the buffer sleeve can primarily absorb energy through the frictional resistance between the buffer sleeve and the door suction base, then the residual energy is transferred to the damping piece, the damping piece absorbs energy for the second time, and finally the deceleration buffering of the door leaf, namely the magnet assembly arranged on the door leaf, is completed.
