Description

Technical Field

[0001] The utility model belongs to the technical field of friction rubber strips at sliding doors and windows, and specifically relates to a low-friction rubber strip. Background Art

[0002] Currently, sliding doors and windows on the market are usually sealed with wool strips, and their airtight and watertight performance is far behind that of rubber strips. In order to improve some performance, non-woven fabrics or films are often added to the wool strips, but the effect is not much improved, and the noise and pushing and pulling force are also increased. Utility Model Content

[0003] The utility model provides a low-friction rubber strip, which selects a rubber strip with greater friction when sliding, and arranges a sliding guide layer on the surface of the rubber strip, which greatly improves the airtightness and watertightness of doors and windows without increasing the opening and closing force much.

[0004] The technical means adopted by the utility model are as follows:

[0005] A low-friction rubber strip is arranged between a window frame and a mounting frame supporting the window frame, comprising:

[0006] A fixing part and a contact part;

[0007] The fixing portion is embedded in the installation frame, and the contact portion is located between the fixing portion and the window frame and is fixedly connected to the fixing portion;

[0008] The contact portion has an arc-shaped structure protruding toward the window frame, and a sliding guide layer is arranged on a surface of the arc-shaped structure in contact with the window frame.

[0009] Preferably, the installation frame has a concave notch arranged toward the window frame, and the inner end of the concave notch has a bayonet recessed in a direction perpendicular to the notch;

[0010] The fixing part includes a first fixing rod embedded in the bayonet and a second fixing rod abutting against the outside of the concave notch. A connecting rod perpendicular to the first and second fixing rods is arranged between the first and second fixing rods.

[0011] Preferably, the contact portion further comprises a straight structure fixedly connected to the second fixing rod, the arc structure is fixedly connected to the straight structure, and a certain space is left between the arc structure and the second fixing rod.

[0012] Preferably, a protruding structure is further provided on the side of the second fixing rod close to the window frame, and the protruding structure is located between the second fixing rod and the arc structure at an end away from the straight structure, with a certain space left between the protruding structure and the arc structure.

[0013] Preferably, two connecting rods are provided, which are respectively arranged against two side edges of the concave notch.

[0014] Preferably, the fixing portion is made of hard TPV, and the contact portion is made of soft TPV.

[0015] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0016] This solution uses rubber strips to seal sliding doors and windows. Due to the characteristics of the rubber strips, the friction is relatively large when sliding. A sliding guide layer is set on the surface of the rubber strips. This greatly improves the airtightness and watertightness of the doors and windows without significantly increasing the opening and closing force. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1-2 As shown, the utility model provides a low friction rubber strip, which is arranged between a window frame 2 and a mounting frame 1 supporting the window frame 2. The rubber strip 4 includes: a fixing portion 41 and a contact portion 42; wherein the fixing portion 41 is embedded in the mounting frame 1, as shown in FIG. Figure 2As shown, the installation frame 1 has a concave notch 11 arranged toward the window frame 2, and the inner end of the concave notch 11 has a bayonet 12 recessed in a direction perpendicular to the notch; the fixing portion 41 includes a first fixing rod 411 embedded in the bayonet 12, and includes a second fixing rod 412 abutting against the outer side of the concave notch 11, and a connecting rod 413 perpendicular to the first fixing rod 411 and the second fixing rod 412 is arranged between the first fixing rod 411 and the second fixing rod 412, and the fixing portion 41 is firmly connected to the installation frame 1 through the engagement and matching of the first fixing rod 411 and the bayonet 12, and in order to further improve the stability, as shown in FIG. Figure 1 As shown, two connecting rods 413 are provided, which are respectively disposed against two side edges of the concave notch 11 , so that the fixing portion 41 is more stable relative to the installation frame 1 .

[0029] As well as Figure 2 As shown, the contact portion 42 is located between the fixing portion 41 and the window frame 2, and is fixedly connected to the fixing portion 41; the contact portion 42 has an arc structure 422 protruding toward the window frame 2, and the surface of the arc structure 422 in contact with the window frame 2 is provided with a guide layer 43 to increase sliding properties.
