Abstract

The invention relates to the technical field of hardware and provides a buffering door stopper. The door stopper is provided with a door stopper ball, a buffer 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. The invention realizes the technical effect of slow movement of the door stopper pull rod and achieves the purpose of eliminating the noise generated by collision when the door stopper is used.

Description

Buffer door stopper

technical field

The invention relates to the technical field of hardware, in particular to door suction products.

Background technique

At present, door stoppers widely used in the market usually use metal and metal to attract and close under the action of magnetic force. When the two pieces of metal are closed, there will be a collision between the two pieces of metal, which will make a loud sound.

Contents of the invention

The purpose of the present invention is to eliminate the collision noise when the door stopper is in use, and to provide a cushioned door stopper.

The technical solution adopted in the present invention is: a door suction ball, a buffer rubber ring, a door suction rod and a sleeve assembly are provided, the door suction ball is embedded in one end of the door suction rod, and the buffer rubber ring is nested in the door suction The other end of the door pull rod is inserted into the sleeve assembly and a limit ring is set at the end of the door pull rod; the sleeve assembly consists of a sleeve and a device. It is composed of a damping buffer assembly and an elastic buffer assembly, the damping buffer assembly is located at the left end of the sleeve, and the elastic buffer assembly is located at the right end of the sleeve; the damping buffer assembly is composed of two silent fixed rings, two sealing rings and Consisting of appropriate amount of damping grease, the center of the silent fixing ring is provided with an embedded hole and a damping cavity, the embedded hole is nested in the middle of the door pull rod, the damping grease is filled in the damping cavity, and the sealing ring is sealed at both ends of the damping cavity; the elastic buffer component It consists of a return spring, a fixed base, and a fixed boot. The fixed base is embedded on the outside of the sleeve, and the fixed boot is embedded on the inside of the sleeve. One end of the return spring presses against the right side of the limit ring at the end of the door pull rod. , and the other end presses against the left side of the fixed boot.

In the free state (door closed), the door stopper rod extends out of the sleeve under the elastic force of the return spring until the limit ring at the bottom end of the door stopper rod is close to the right side of the silent fixed ring; when the door is opened, the door stopper ball is pressed by external force , the door suction rod moves to the right and retracts into the sleeve until the buffer rubber ring presses against the left end face of the sleeve. The return spring is subjected to the stress generated by the pressure, which reduces the moving speed of the door suction rod; under the condition of no external force, the door suction rod moves to the left under the elastic force of the return spring. The resistance effect of the sealing ring and the damping grease reduces the moving speed of the door suction rod; through the above technical scheme, the present invention realizes the technical effect of the slow movement of the door suction rod, and achieves the purpose of eliminating the noise generated by the collision when the door suction is in use.

Detailed ways

The present invention can be implemented in the following ways:

As shown in Figure 1 and Figure 2, the present invention is provided with a door stopper ball 1, a buffer rubber ring 2, a door stopper rod 3 and a sleeve assembly 4, the door stopper ball 1 is embedded in one end of the door stopper rod 3 , the buffer rubber ring 2 is nested on the door stopper rod 3, and placed between the door stopper ball 1 and the sleeve assembly 4, the other end of the door stopper rod 3 is inserted into the sleeve assembly 4 and placed on the door stopper rod 3 The end is provided with a limit ring 31; the sleeve assembly 4 is composed of a sleeve 41 and a damping buffer assembly 42 and an elastic buffer assembly 43 disposed therein. The damping buffer assembly 42 is located at the left end of the sleeve 4, and the elastic buffer assembly 43 is located at the right end of the sleeve 4; the damping buffer assembly 42 is composed of two silent fixing rings 421, two sealing rings 422 and an appropriate amount of damping grease 423, the center of the silent fixing ring 421 is provided with an embedded hole 4211 and a damping cavity 4212, an embedded The hole 4211 is nested in the middle of the door pull rod 3, the damping grease 423 is filled in the damping cavity 4212, and the sealing ring 422 is blocked at both ends of the damping cavity 4212; the elastic buffer assembly 43 is composed of a return spring 431, a fixed base 432, A fixed tail sleeve 433 is formed, the fixed base 432 is embedded and fixed on the outside of the sleeve 41, the fixed tail sleeve 433 is embedded and fixed on the inside of the sleeve 41, and one end of the return spring 431 is pressed against the right side of the limit ring 31 at the tail end of the door pull rod 3, The other end presses against the left side of the fixed boot 433 .

As shown in Figure 3 to Figure 5, in the free state (door closed), the door suction rod 3 extends out of the sleeve 41 under the elastic force of the return spring 431 until the limit ring 31 at the bottom end of the door suction rod 3 is close to the silent fixing ring 421 Right side; when the door is opened, the door suction ball 1 is pressed by external force, the door suction rod 3 moves to the right and retracts into the sleeve 41 until the buffer rubber ring 2 is pressed against the left end surface of the sleeve 41. During this process, the door The suction rod 3 is affected by the resistance of the sealing ring 422 and the damping grease 423 in the silent fixed ring 421, and the stress generated by the pressure of the return spring 431 reduces the moving speed of the door suction rod 3; in the absence of external force, the door suction The pull rod 3 moves to the left under the force of the return spring 431. During this process, the door pull rod 3 is subjected to the resistance of the sealing ring 422 and the damping grease 423 in the silent fixing ring 421, so that the moving speed of the door pull rod 3 is reduced; The present invention realizes the technical effect of the slow movement of the door suction rod 3 through the above technical proposal, and achieves the purpose of eliminating the noise generated by the collision of the door suction when it is in use.
