Description

Technical Field

[0001] This utility model relates to the field of sealing strip technology, specifically to a high-strength sealing strip. Background Technology

[0002] As a key component for sealing, dustproofing, sound insulation, and cushioning, sealing strips are widely used in various fields such as building doors and windows, automobile manufacturing, and home appliances. With the continuous improvement of sealing performance requirements in modern industry, sealing strips not only need to have good sealing fit, but also need to meet the high strength requirements of resisting deformation, wear, and environmental aging during long-term use.

[0003] Currently, most common sealing strips on the market adopt a single structural design, such as a simple frame or semi-circular solid structure. These structures are prone to insufficient overall strength and poor deformation recovery after being subjected to external pressure or long-term use, leading to increased sealing gaps and loss of sealing effect. While some improved sealing strips attempt to increase strength by increasing thickness, this increases material costs and makes them difficult to adapt to the installation space requirements of precision equipment.

[0004] To address the strength issue, some technologies incorporate internal reinforcement structures within the sealing strip. However, existing reinforcement methods have significant drawbacks: First, the reinforcement is not tightly integrated with the sealing strip body, making it prone to loosening or detachment during use, thus failing to provide sustained reinforcement. Second, the uneven distribution of the reinforcement structure leads to substantial strength differences across different parts of the sealing strip, with weaker areas prone to failure. Third, the design of the sealing contact surface is inadequate, resulting in some sealing strips not adhering tightly to the sealing surface, creating sealing dead zones. Furthermore, the outer surface lacks sufficient wear resistance and anti-slip properties, affecting service life. In addition, the filling materials used in existing sealing strips are mostly ordinary rubber, which performs poorly in terms of aging resistance and bonding strength, further limiting the overall performance improvement of the sealing strip. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-strength sealing strip that can effectively solve the problems in the existing technology.

[0006] This utility model provides a high-strength sealing strip, including a frame seal and a semi-circular seal fixed to one side of the frame seal. Both the frame seal and the semi-circular seal have a through groove in the middle. A reinforcing rib is inserted and fixed in the through groove, and the gap between the reinforcing rib and the through groove is filled with filler glue.

[0007] Furthermore, the frame seal is a hollow structure, and a protrusion is fixed on the inner wall of the frame seal, and the cross-section of the protrusion is a triangular structure.

[0008] Furthermore, two sets of circular raised strip structures are fixed on the outer side of the semi-circular seal.

[0009] Furthermore, the through grooves are evenly distributed in an array within the frame-type seal.

[0010] Furthermore, the through grooves are evenly distributed in an array within the semi-circular seal.

[0011] Furthermore, the filler adhesive is made of epoxy resin.

[0012] In this invention, the high-strength sealing strip features a double-reinforcement structure of "reinforcing rib + filler" by inserting a fixed reinforcing rib into the through-groove in the middle of the frame seal and the semi-circular seal, and filling the gap between the reinforcing rib and the through-groove with epoxy resin filler. Epoxy resin material possesses excellent bonding strength and mechanical properties, firmly bonding the reinforcing rib to the sealing strip body and preventing it from loosening or detaching. Simultaneously, the reinforcing rib effectively disperses external forces, enhancing the sealing strip's tensile and compressive strength. Furthermore, the through-groove is evenly distributed in an array within both the frame seal and the semi-circular seal, ensuring the reinforcement structure uniformly covers the entire sealing strip, resulting in consistent strength across all parts and effectively extending the sealing strip's service life.

[0013] In this device, the frame seal adopts a hollow structure, which reduces the overall weight while enhancing the elastic deformation capability of the sealing strip, allowing it to better adapt to the contours of different sealing surfaces. The triangular protrusions fixed on the inner side can form multiple tight contacts with the sealing surface after installation, filling tiny gaps and effectively preventing the intrusion of dust, moisture, and other impurities, thus improving the reliability of the seal. The two sets of circular convex strips on the outer side of the semi-circular seal increase the contact friction with the sealing surface, preventing the sealing strip from shifting during use. Furthermore, the convex strip structure forms multiple sealing defenses, further enhancing the sealing effect. Attached Figure Description

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example: A high-strength sealing strip, see attached diagram. Figure 1 -Appendix Figure 4 The high-strength sealing strip includes a frame-type seal 1 and a semi-circular seal 2 fixed to one side of the frame-type seal 1. Both the frame-type seal 1 and the semi-circular seal 2 have a through groove 11 extending through their center. A reinforcing rib 4 is inserted and fixed within the through groove 11, and the gap between the reinforcing rib 4 and the through groove 11 is filled with epoxy resin. This high-strength sealing strip forms a double-reinforcement structure of "reinforcing rib 4 + filling resin" by inserting and fixing the reinforcing rib 4 within the through groove 11 in the center of the frame-type seal 1 and the semi-circular seal 2, and filling the gap between the reinforcing rib 4 and the through groove 11 with epoxy resin filler. Epoxy resin material has excellent bonding strength and mechanical properties, which can firmly bond the reinforcing rib 4 to the sealing strip body, preventing the reinforcing rib 4 from loosening and detaching. At the same time, the reinforcing rib 4 can effectively disperse external forces, improving the tensile and compressive strength of the sealing strip.

[0020] The frame seal 1 has a hollow structure, and a protrusion 3 is fixed on the inner wall of the frame seal 1. The cross-section of the protrusion 3 is triangular. Two sets of circular raised strips 21 are fixed on the outer side of the semi-circular seal 2. The hollow structure of the frame seal 1 reduces the overall weight while enhancing the elastic deformation capability of the sealing strip, allowing it to better adapt to the contours of different sealing surfaces. The triangular protrusion 3 fixed on the inner side can form multiple tight contacts with the sealing surface after installation, filling tiny gaps and effectively preventing the intrusion of dust, moisture, and other impurities, thus improving the reliability of the seal. The two sets of circular raised strips 21 on the outer side of the semi-circular seal 2 increase the contact friction with the sealing surface, preventing the sealing strip from shifting during use. Furthermore, the raised strips 21 structure can form multiple sealing defenses, further improving the sealing effect.

[0021] The through-grooves 11 are evenly distributed in an array within the frame seal 1; the through-grooves 11 are also evenly distributed in an array within the semi-circular seal 2; the filler is made of epoxy resin; the hollow frame seal 1 structure reduces the amount of raw materials used and lowers production costs while ensuring strength; the equidistant array design of the through-grooves 11 facilitates industrial mass production and improves production efficiency. The epoxy resin filler not only possesses good adhesion and mechanical strength but also excellent aging and corrosion resistance, adapting to the needs of different environments and reducing the frequency of later maintenance and replacement, indirectly lowering operating costs. The overall structural design is reasonable, balancing high strength, high sealing performance, and economy, and has broad application prospects.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
