A buffer strip is set in the middle of the collision strip No. 2, and through holes are set on both sides of it. A through hole is set on the edge of the surrounding to form a chamber to absorb the collision strip and prevent rebound.
Through the design of the edge and through holes, high-pressure and negative pressure effects are formed, the deformation and rebound strength of the buffer strip are reduced, doors and windows are prevented from being rebounded, and closer doors and windows are closed.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-collision strips, and particularly relates to an anti-collision component for preventing the rebound of doors and windows. Background Art
[0002] Anti-collision strips are commonly used on sliding doors and windows. The anti-collision strips achieve shock absorption and buffer protection for the doors and windows when they are closed through the elasticity of the material itself and the buffer cavities inside. The buffer cavities compress and absorb energy when the doors and windows are closed. However, after the buffer cavities are compressed to a certain extent, they will rebound, resulting in a gap remaining after the doors and windows are rebounded and not closing tightly. Content of the Utility Model
[0003] The utility model provides an anti-collision component for preventing the rebound of doors and windows in order to solve the above technical deficiencies, which can prevent the doors and windows from being bounced open when they are closed.
[0004] The utility model discloses an anti-collision component for preventing the rebound of doors and windows, which includes a first anti-collision strip and a second anti-collision strip. A buffer strip is arranged in the middle of the second anti-collision strip along its length direction. The inside of the buffer strip is hollow. One first through hole communicating with the inside of the buffer strip is arranged on each side of the buffer strip. A border is arranged around the end face of the second anti-collision strip where the buffer strip is arranged. A second through hole is arranged on the border. The shape enclosed by the border matches the first anti-collision strip, and the first anti-collision strip is embedded in the border.
[0005] When the above technical solution is used, the first anti-collision strip is pasted on the door frame or window frame, and the second anti-collision strip is pasted on the door or window. When the doors and windows are closing, the first anti-collision strip is embedded in the border of the second anti-collision strip. When the first anti-collision strip contacts the buffer strip, the buffer strip compresses and absorbs energy, playing a buffering role. At the same time, due to the existence of the border, the air between the first anti-collision strip and the second anti-collision strip is compressed, and part of the compressed air is discharged from the second through hole. The compressed air plays a further buffering role, reducing the deformation amount of the buffer strip. When the buffer strip rebounds after being compressed to a certain extent, the distance between the first anti-collision strip and the second anti-collision strip becomes larger. Since a chamber is formed between the border, the first anti-collision strip and the second anti-collision strip, a negative pressure is formed in the chamber in a short time, thereby sucking the second anti-collision strip through the negative pressure to prevent the doors and windows from being rebounded.
[0006] Further, the inner side corners of the border are chamfered, so that the first anti-collision strip can be more easily embedded in the border.
[0007] Further, the number of the first through holes is equal to the number of the second through holes, and the first through holes and the second through holes are aligned one by one. Such a setting facilitates the processing of the first through holes and the second through holes.
[0008] An anti-collision component for preventing doors and windows from rebounding obtained by the present utility model has the beneficial effects that through the setting of the surrounding edge, high pressure is formed inside the surrounding edge when the doors and windows are closed, which can reduce the deformation amount of the buffer strip, thereby reducing the rebound force of the buffer strip. At the same time, the setting of the surrounding edge forms negative pressure inside during rebound, which can play an adsorption role to prevent the doors and windows from being bounced open.

[0012] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to describe in detail the specific implementation manners, structures, features, and effects according to the present utility model as follows.
[0013] Embodiment 1:
[0014] As Figure 1 , 2 , shown in Figure 3, the present utility model discloses an anti-collision component for preventing doors and windows from rebounding, including a first anti-collision strip 1 and a second anti-collision strip 4. A buffer strip 5 is arranged in the middle of the second anti-collision strip 4 along its length direction. The inside of the buffer strip 5 is hollow. On both sides of the buffer strip 5, there are first through holes 6 communicating with the inside of the buffer strip 5. Around the end face of the second anti-collision strip 4 where the buffer strip 5 is arranged, there is a surrounding edge 2. There are second through holes 3 on the surrounding edge 2. The number of the first through holes 6 is equal to the number of the second through holes 3, and the first through holes 6 and the second through holes 3 are aligned one by one. The shape surrounded by the surrounding edge 2 matches the first anti-collision strip 1. The inner side corners of the surrounding edge 2 are chamfered. The first anti-collision strip 1 is embedded in the surrounding edge 2.
[0015] When the above technical solution is in use, the first anti-collision strip 1 is pasted on the door frame or window frame, and the second anti-collision strip 4 is pasted on the door or window. When the door or window is being closed, the first anti-collision strip 1 is embedded in the surrounding edge 2 of the second anti-collision strip 4. When the first anti-collision strip 1 contacts the buffer strip 5, the buffer strip 5 compresses and absorbs energy, playing a buffering role. At the same time, due to the existence of the surrounding edge 2, the air between the first anti-collision strip 1 and the second anti-collision strip 4 is compressed, and part of the compressed air is discharged from the second through hole 3. The compressed air plays a further buffering role, reducing the deformation amount of the buffer strip 5. When the buffer strip 5 rebounds after being compressed to a certain extent, the distance between the first anti-collision strip 1 and the second anti-collision strip 4 becomes larger. Since a chamber is formed between the surrounding edge 2, the first anti-collision strip 1 and the second anti-collision strip 4, a negative pressure is formed in the chamber in a short time, thereby sucking the second anti-collision strip 4 through the negative pressure to prevent the door or window from rebounding.
