[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, a door and window sealing strip includes a cap head 1, a tenon core portion 2 is centrally provided inside the cap head 1, and the cap head 1 includes a brim 11. The brim 11 is divided into the following structures according to its structure:

[0022] vertical portion 12;

[0023] An outer web 13 is provided on a first side of the vertical portion 12, and an angle between the two is 65 degrees;

[0024] A horizontal portion 15 is provided at the end of the vertical portion 12 and extends toward one side of the tenon core portion 2 . The ends of the horizontal portion 15 are respectively provided with hard strips 14 distributed toward the cap head 1 and the tenon core portion 2 .

[0025] In the above technology, the tenon core part 2 is inserted between the window frame profile and the glass, and then during the downward pressing process, the horizontal part 15 contacts the window frame profile, thereby forming a sealed space. As the pressure is pressed, the gas in the cavity formed by the vertical part 12, the horizontal part 15, the cap head 1 and the glass is discharged, thereby achieving sealing.

[0026] When the cap head 1 is squeezed by the window frame profile and the gas in the cavity is discharged, the cap head 1 is deformed, the outer web 13 extends outward, and a water-containing belt is formed between the outer web 13 and the vertical part 12 to prevent liquid from penetrating along the gap between the sealing strip and the profile.

[0027] As a further embodiment provided by the present invention, the present invention further comprises an elastic plastic member 3 , which is slidably disposed in the door and window sealing strip, and the end portion of the first end is located in the horizontal portion 15 .

[0028] Furthermore, the tenon core portion 2 is provided with anti-slip fins 4 arranged in a linear array, and the second end of the elastic plastic member 3 is connected to the last stage of the anti-slip fin 4 near the end of the tenon core portion 2 .

[0029] Specifically, when the tenon core portion 2 in the above embodiment is inserted between the window frame profile and the glass, the anti-slip fins 4 will be deformed due to the friction with the window frame profile and the glass, and eventually switch from facing downward to facing upward, thereby achieving the anti-pullout effect, and when the anti-slip fins 4 are deformed, they will pull the elastic plastic part 3, thereby pulling the horizontal portion 15 to shrink and deform, that is, the end of the horizontal portion 15 will move away from the tenon core portion 2.

[0030] As another embodiment further provided by the present invention, the anti-slip fin 4 is an arc-shaped structure, with its end facing the end of the tenon core part 2, and the angle between it and the end of the tenon core part 2 is 135°-145°.

[0031] As another embodiment further provided by the present invention, the anti-slip webs 4 are arranged in a stepped manner along the axial direction of the tenon core part 2 , and the length thereof decreases gradually from the end portion of the tenon core part 2 .

[0032] An arc-shaped pulling section 5 is provided on the tenon core portion 2 , and an end portion of the arc-shaped pulling section 5 is connected to an end portion of the anti-slip fin 4 .

[0033] Specifically, in the above embodiment, the arc-shaped pulling section 5 is used to limit the change in the included angle after the deformation of the anti-slip fin 4, thereby increasing the damping force in the pulling-out direction.

[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
