Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of door and window sealing, and particularly relates to an anti - detachment sealing strip. Background Art
[0002] The sealing strip for doors and windows, also known as the door and window sealing buckle or sealing bead, is an additional accessory dedicated to enhancing the sealing effect during door and window installation. Its main function is to cooperate with the sealing rubber strip or other sealing materials to further improve the sealing performance when the doors and windows are closed, preventing rain, wind, dust, and noise from penetrating through the gaps between the doors and windows into the room. The sealing strip is usually made of materials such as plastic, rubber, silicone, metal, etc. According to the structural characteristics of different doors and windows, it is designed into various shapes and sizes, and can adapt to different combination methods between the window frame and the glass, and between the window frame and the window sash. During installation, the sealing strip is embedded in the specific grooves of the door or window frame or sash, and is fixed to the door and window structure through its own elasticity or through fasteners, ensuring that it can tightly press against the corresponding door and window components when the doors and windows are closed, thus forming a reliable sealing barrier.
[0003] The existing sealing strip has poor sealing performance, and there will be hard friction between the aluminum profiles at the sealing part, resulting in wear between the aluminum profiles, and there will also be frictional abnormal sounds, affecting normal use. Moreover, the deformation of the sealing strip is large, and when the glass is under positive pressure wind, the sealing strip may fall off, leading to the risk of glass falling. Summary of the Utility Model
[0004] The utility model aims to provide an anti - detachment sealing strip to solve the technical problems of poor sealing effect and insufficient connection strength of the sealing strip in the prior art, which may cause detachment.
[0005] To solve the above - mentioned technical problems, the utility model adopts the following technical solutions:
[0006] An anti - detachment sealing strip includes a profile body. The profile body has a U - shaped structure. One end of the profile body is provided with an anti - detachment hook structure, and the other end of the profile body is provided with a special - shaped side strip. The special - shaped side strip is located on the inner wall of the profile body. A rubber strip installation groove is formed between the special - shaped side strip and the profile body. The cross - section of the rubber strip installation groove is a superior arc shape, and the rubber strip installation groove is used for installing a foaming rubber strip. A hook structure is provided at the end of the special - shaped side strip.
[0007] Further, a wear - resistant layer is provided on the outer wall of the anti - detachment hook structure.
[0008] Further, a wear - resistant surface is provided at the end of the profile body.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The anti-disengagement hook structure of the present utility model cooperates with the hook-shaped structure on the aluminum profile to prevent the buckle strip from falling off when the glass is under positive pressure wind, ultimately resulting in the glass falling; in addition, one end of the profile body 1 is buckled with the aluminum profile through a special-shaped edge strip, and the foamed rubber strip in the rubber strip installation groove is made of ethylene propylene diene monomer (EPDM) material. The foamed rubber strip can increase the sealing performance, prevent air leakage at the connection, and can also relieve the noise generated by the vibration of the aluminum profile while achieving sealing, realizing a soundproof effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The drawings are used to provide a further understanding of the present utility model, and constitute a part of the specification. Together with the embodiments of the present utility model, they are used to explain the present utility model, and do not constitute a limitation to the present utility model. In the drawings:
[0011] Figure 1 is a schematic structural diagram of an anti-disengagement and sealing buckle strip of the present utility model;
[0012] Figure 2 is a use state diagram of an anti-disengagement and sealing buckle strip of the present utility model;
[0013] Figure 3 is Figure 2 an enlarged view of the H position in DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0015] The following further describes the present utility model in detail with reference to the embodiments.
[0016] As Figure 1 shown, a specific embodiment of an anti-disengagement and sealing buckle strip provided by the present utility model:
[0017] An anti-disengagement and sealing buckle strip includes a profile body 1. The profile body 1 is in a U-shaped structure. One end of the profile body 1 is provided with an anti-disengagement hook structure 2, and the other end of the profile body 1 is provided with a special-shaped edge strip 3. The special-shaped edge strip 3 is located on the inner wall of the profile body 1. A rubber strip installation groove is formed between the special-shaped edge strip and the profile body 1. The cross-section of the rubber strip installation groove is a superior arc shape, and the rubber strip installation groove is used for installing a foamed rubber strip 4. A hook structure 5 is provided at the end of the special-shaped edge strip 3.
[0018] As Figure 2 and Figure 3As shown, it is the usage state diagram of the anti - detachment sealing strip in this embodiment. The anti - detachment sealing strip is installed on the aluminum profile 100. The anti - detachment hook structure 2 cooperates with the hook - shaped structure on the aluminum profile 100 to prevent the strip from falling off when the glass is under positive - pressure wind, which may ultimately lead to the glass falling. In addition, one end of the profile body 1 is buckled with the aluminum profile 100 through the special - shaped edge strip 3. The foamed rubber strip 4 in the rubber strip installation groove is made of ethylene propylene diene monomer (EPDM) material. The foamed rubber strip 4 can increase the sealing performance and prevent air leakage at the connection. Moreover, there is hard friction between the aluminum profile 100 and the profile body 1, which may cause abnormal noise. The setting of the foamed rubber strip 4 can reduce their direct contact.
[0019] Preferably, there will also be contact friction between the anti - detachment hook structure 2 and the aluminum profile 100. Therefore, a wear - resistant layer 6 can be provided on the outer wall of the anti - detachment hook structure 2, and a wear - resistant surface 7 is provided at the end of the profile body 1.
