Description

Technical Field

[0001] This utility model relates to the field of door and window sealing technology, specifically to a door and window sealing strip fixing structure with adjustable tightness. Background Technology

[0002] In the use of doors and windows, sealing strips play a crucial role. They can effectively prevent external dust, rainwater, noise and other pollutants from entering the room, while also reducing heat loss and improving the sealing performance and energy efficiency of doors and windows.

[0003] However, existing door and window sealing strip fixing structures typically employ a fixed installation method, making it difficult to adjust the tightness of the sealing strip after installation. Over long-term use, the sealing performance deteriorates due to aging and deformation of the sealing strip, failing to meet actual usage requirements. Furthermore, different door and window frames may have different requirements for the tightness of the sealing strip, making existing fixing structures ill-suited to diverse installation needs.

[0004] Therefore, a fixing structure that allows for easy adjustment of the tightness of the sealing strip is needed to improve the sealing performance and reliability of doors and windows. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides an adjustable tightness door and window sealing strip fixing structure. This solves the problems of non-adjustable tightness and difficulty in guaranteeing sealing performance in existing door and window sealing strip fixing structures. It allows for convenient adjustment of the tightness of the sealing strip according to actual usage needs, thereby improving the sealing performance and reliability of doors and windows.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable tightness door and window sealing strip fixing structure, including a mounting base, the mounting base being used to fix it on a door and window frame, the surface of the mounting base having a groove extending along the length direction of the mounting base, the mounting base having a sealing strip installed in the groove, and the mounting base having an adjustment component inside;

[0007] The adjustment assembly includes an adjustment block, an adjustment bolt, and an elastic element. The adjustment block is disposed in a groove inside the mounting base. The adjustment bolt is threaded into a threaded hole on the surface of the mounting base. One end of the adjustment bolt is inserted into the mounting base and threadedly connected to a threaded through hole on the surface of the adjustment block. The elastic element is disposed between the adjustment block and the inner wall of the groove.

[0008] Preferably, the adjusting block has an arc-shaped extrusion surface on the side near the sealing strip, and the curvature of the arc-shaped extrusion surface is adapted to the inner contour of the sealing strip.

[0009] Preferably, the elastic element is a spring structure, with the spring sleeved on the adjusting bolt, and one end of the spring abutting against the surface of the adjusting block, and the other end abutting against the inner wall surface of the groove.

[0010] Preferably, two limiting blocks are symmetrically installed on the surface of the adjusting block. The limiting blocks slide within the grooves opened inside the mounting base, and the two ends of the two limiting blocks are adapted to the grooves.

[0011] Preferably, the head of the adjusting bolt is provided with an operating part that is easy to rotate, and the operating part has a regular hexagonal structure.

[0012] Preferably, the mounting base is further provided with a fixing protrusion for enhancing the fixing effect. The fixing protrusion has a mounting hole, and the mounting base can be fixed to the door and window frame by passing screws through the mounting hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the inclusion of an adjustment component, allows for convenient adjustment of the tightness of the sealing strip. When adjustment is needed, rotating the adjusting bolt moves the adjusting block within the groove, applying varying pressure to the sealing strip to achieve the desired tightness. This adapts to different usage scenarios and the tightness requirements of door and window frames. The arc-shaped extrusion surface of the adjusting block matches the inner contour of the sealing strip, ensuring uniform pressure and improved sealing performance. The spring structure provides buffering and reset functions, making adjustment smoother and providing stable support after adjustment. The limiting block limits and guides the adjusting block, ensuring accuracy and stability. The hexagonal operating part facilitates rotation with tools such as wrenches, simplifying tightness adjustment. The fixing protrusion enhances the fixation of the mounting base. These design features collectively improve the practicality and reliability of this invention. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides an adjustable tightness door and window sealing strip fixing structure, including a mounting base 1, which is used to fix the door and window frame. The surface of the mounting base 1 is provided with a groove 2, which extends along the length direction of the mounting base 1. The mounting base 1 is installed with a sealing strip 3 in the groove 2. An adjustment component is provided inside the mounting base 1.

[0022] The adjustment assembly includes an adjustment block 4, an adjustment bolt 5, and an elastic element 7. The adjustment block 4 is installed in a groove 2 inside the mounting base 1. The adjustment bolt 5 is threaded into a threaded hole on the surface of the mounting base 1. One end of the adjustment bolt 5 is inserted into the mounting base 1 and threadedly connected to a threaded through hole on the surface of the adjustment block 4. The elastic element 7 is located between the adjustment block 4 and the inner wall of the groove 2. By adjusting the adjustment bolt 5 in the adjustment assembly, the position of the adjustment block 4 in the groove 2 can be easily adjusted, thereby changing the degree of compression on the sealing strip 3 and realizing flexible adjustment of the tightness of the sealing strip 3. It can adapt to the slight deformation of the door and window caused by environmental changes and always maintain a good sealing effect.

[0023] like Figures 1 to 4 As shown, the adjusting block 4 has an arc-shaped extrusion surface on the side near the sealing strip 3. The curvature of the arc-shaped extrusion surface matches the inner contour of the sealing strip 3. This design allows the adjusting block 4 to be subjected to more uniform force when extruding the sealing strip 3, avoiding excessive local force on the sealing strip 3 and thus preventing damage. This further improves the sealing effect and the stability of the strip.

[0024] The elastic element 7 is a spring structure. The spring is sleeved on the adjusting bolt 5, and one end of the spring abuts against the surface of the adjusting block 4, while the other end abuts against the inner wall surface of the groove 2. As an elastic element 7, the spring has good elastic recovery performance and can provide stable support force after adjusting the tightness.

[0025] Two limiting blocks 8 are symmetrically installed on the surface of the adjusting block 4. The limiting blocks 8 slide in the groove 2 opened inside the mounting base 1. The two ends of the two limiting blocks 8 are adapted to the groove 2. The setting of the limiting blocks 8 can limit and guide the movement of the adjusting block 4, prevent the adjusting block 4 from shifting or rotating during the adjustment process, and ensure the accuracy and stability of the adjustment.

[0026] The head of the adjusting bolt 5 is provided with an operating part that is easy to rotate. The operating part is a regular hexagonal structure. This regular hexagonal operating part 6 is easy to rotate with tools such as wrenches, making the adjustment process more labor-saving and convenient, and making it easier to adjust the tightness.

[0027] like Figures 1 to 4 As shown, the mounting base 1 is also provided with a fixing protrusion 9 to enhance the fixing effect. The fixing protrusion 9 is provided with a mounting hole. The mounting base 1 can be fixed to the door and window frame by passing screws through the mounting hole. The setting of the fixing protrusion 9 and the mounting hole can make the mounting base 1 more firmly fixed to the door and window frame, ensuring the stability of the entire fixing structure.

[0028] Working principle and process: During installation, first fix the mounting base 1 to the door or window frame using screws through the mounting holes on the fixing protrusion 9, ensuring that the mounting base 1 is firmly installed. Then, install the sealing strip 3 into the groove 2 on the surface of the mounting base 1.

[0029] When adjusting the tightness of the sealing strip 3, use a wrench or similar tool to rotate the hexagonal operating part 6 of the adjusting bolt 5. Since the adjusting bolt 5 is threadedly connected to the threaded through hole on the surface of the adjusting block 4, as the adjusting bolt 5 rotates, the adjusting block 4 moves along the axial direction of the adjusting bolt 5 within the groove 2. When the adjusting bolt 5 rotates clockwise, it pushes the adjusting block 4 closer to the sealing strip 3, and the arc-shaped pressing surface of the adjusting block 4 gradually presses against the sealing strip 3, increasing the pressure on the sealing strip 3 and thus increasing its tightness. When the adjusting bolt 5 rotates counterclockwise, under the elastic force of the elastic element 7 (spring), the adjusting block 4 moves away from the sealing strip 3, reducing the pressure on the sealing strip 3 and decreasing its tightness. During the movement of the adjusting block 4, the limiting block 8 slides within the groove 2 inside the mounting base 1, limiting and guiding the adjusting block 4 to ensure smooth movement without deviation or rotation.

[0030] Through the above adjustment methods, the tightness of the sealing strip 3 can be flexibly adjusted according to actual usage needs to achieve the best sealing effect and improve the sealing performance and reliability of doors and windows.
