[0002] In the fields of construction, machinery, and automobiles, sealing strips are widely used in doors, windows, pipes, equipment interfaces, etc., to provide waterproofing, dustproofing, shock absorption, and sound insulation. Traditional sealing strips usually adopt an integral structure, with the installation part and the sealing part fixedly connected. This has the following technical defects: 1. When the sealing part wears, ages, or is damaged due to long-term use, the entire sealing strip needs to be replaced, resulting in high maintenance costs and cumbersome operation; 2. The integral structure cannot flexibly adjust the shape or material of the sealing part, making it difficult to meet diverse sealing needs. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a replaceable sealing strip.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A replaceable sealing strip includes a sealing part and an installation part that are arranged vertically and detachably connected. The installation part has a T-shaped cross-section and includes a horizontal base plate and an insertion plate located on the lower side of the horizontal base plate. The sealing part includes a connecting base with a rectangular cross-section. A sealing element is provided at the upper end of the connecting base, and a connecting opening is provided at the lower end. The connecting opening is fitted onto the horizontal base plate, and both sides of the horizontal base plate are detachably connected to the connecting opening through a first snap-fit ​​structure. The upper side of the horizontal base plate is detachably connected to the connecting opening through a second snap-fit ​​structure.

[0006] In some embodiments, the first snap-fit ​​structure includes first flange hooks disposed on both sides of the horizontal base plate, and first snap-fit ​​grooves that cooperate with the first flange hooks are provided on both sides of the connection opening.

[0007] In some embodiments, a positioning groove is provided on the lower side of the first flange hook, and a positioning flange that can be engaged into the positioning groove is provided on the first snap-fit ​​groove.

[0012] In some embodiments, the seal has a triangular cross-section and a rounded corner at the top.

[0013] In some embodiments, the seal has an M-shaped cross-section.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The sealing part and the mounting part are detachably connected. When the sealing part is worn or aged, there is no need to replace the entire rubber strip. Only the sealing part needs to be replaced, which greatly reduces maintenance costs and material waste. Moreover, the modular design facilitates quick disassembly and installation, improving maintenance efficiency.

[0016] 2. The horizontal base plate of the mounting section and the plug-in plate form a T-shaped structure. The plug-in plate can be inserted into the mounting groove or the gap of the base, while the horizontal base plate provides lateral support to ensure a firm installation.

[0017] 3. The horizontal base plate is snapped into the connection opening on both sides through the first snap-fit ​​structure to limit the lateral displacement of the sealing part; while the upper part of the horizontal base plate is snapped into the connection opening through the second snap-fit ​​structure to prevent the sealing part from falling off upwards. The overall structural stability is improved by snapping and fixing in multiple directions, including up and down and left and right.

[0018] 4. The sealing part and the mounting part can be made of different materials (e.g., the sealing part uses weather-resistant rubber, and the mounting part uses high-strength plastic) to balance sealing performance and structural strength; in addition, the sealing part of different shapes can be replaced according to different sealing requirements to adapt to the sealing requirements of various scenarios such as doors, windows, and pipes.

[0019] 5. The split design enables standardized production. The mounting section is a general-purpose component, while the sealing section can be customized according to requirements, reducing mold investment and inventory pressure. Attached Figure Description

[0025] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0026] like Figures 1-5 A replaceable sealing strip is shown, comprising a sealing part 1 and an mounting part 2 that are arranged vertically and detachably connected. The mounting part 2 has a T-shaped cross-section and includes a horizontal base plate 3 and an insertion plate 4 located on the lower side of the horizontal base plate 3. The sealing part 1 includes a connecting base 5 with a rectangular cross-section. A sealing element 6 is provided at the upper end of the connecting base 5, and a connecting opening 7 is provided at the lower end. The connecting opening 7 is fitted onto the horizontal base plate 3, and both sides of the horizontal base plate 3 are detachably connected to the connecting opening 7 through a first snap-fit ​​structure. The upper side of the horizontal base plate 3 is detachably connected to the connecting opening 7 through a second snap-fit ​​structure.

[0027] Based on the above structure, the sealing part 1 and the mounting part 2 are detachably connected. When the sealing part 1 is worn or aged, only the sealing part 2 needs to be replaced, without replacing the entire rubber strip, which greatly reduces maintenance and time costs. In the T-shaped structure of the mounting part 2, the plug plate 4 is easy to insert into the mounting groove, and the horizontal base plate 3 provides stable support for the sealing part 1, enhancing installation stability. The connecting base 5 of the sealing part 1 and the sealing element 6 are integrally formed, and the connecting opening 7 is snapped into the horizontal base plate 3 from multiple directions, improving sealing reliability and structural stability. At the same time, the modular design can be adapted to different specifications of sealing elements and installation scenarios.

[0028] In this invention, the first snap-fit ​​structure includes first flange hooks 21 disposed on both sides of the horizontal base plate 3, and first snap-fit ​​grooves 22 that mate with the first flange hooks 21 are provided on both sides of the connection opening 7. During assembly, the connection opening 7 of the sealing part 1 is fitted onto the horizontal base plate 3, and the first flange hooks 21 are snapped into the first snap-fit ​​grooves 22 by pressing. During disassembly, a special tool or external force can be used to disengage the hooks from the grooves. The first flange hooks 21 and the first snap-fit ​​grooves 22 cooperate to form lateral and longitudinal limits, effectively preventing the sealing part 1 from shifting during use, ensuring accurate sealing position, and improving the overall stability and sealing effect of the sealing strip. This structure is simple, easy to assemble and disassemble, and reduces the difficulty of production and maintenance.

[0029] Furthermore, a positioning groove 41 is provided on the lower side of the first flange hook 21, and a positioning flange 42 that can be engaged into the positioning groove 41 is provided on the first snap-fit ​​groove 22; this further strengthens the connection between the sealing part 1 and the mounting part 2, preventing the sealing part 1 from loosening when subjected to lateral or longitudinal forces; compared with the simple hook and groove cooperation, the addition of the positioning structure allows the sealing strip to remain stable under complex working conditions such as vibration and impact, thus extending its service life.

[0030] In this utility model, the second snap-fit ​​structure includes an upper insert plate 31 disposed on the upper side of the horizontal base plate 3, with second flange hooks 32 disposed on both sides of the upper insert plate 31, and an insertion interface 33 disposed on the inner end wall of the connecting opening 7. Second snap-fit ​​grooves 34 are disposed on both sides of the insertion interface 33. The upper insert plate 31 is inserted into the insertion interface 33, and the second flange hooks 32 are snapped into the second snap-fit ​​grooves 34. During installation, the connecting opening 7 of the sealing part 1 is first placed on the horizontal base plate 3, the upper insert plate 31 is inserted into the insertion interface 33, and the sealing part 1 is pressed to make the second flange hooks 32 snap into the second snap-fit ​​grooves 34. Disassembly is performed by reversing the operation.

[0031] Furthermore, cavities 51 are provided on both sides of the interior of the connecting base 5; the cavities 51 on both sides of the interior of the connecting base 5 can increase the flexibility and elasticity of the sealing part 1. When compressed, the cavity 51 can deform to absorb the pressure, so that the sealing part 1 fits more tightly with the sealing surface and improves the sealing performance; at the same time, the cavity 51 can reduce the overall weight of the sealing strip, reduce material costs, and help buffer external impact forces and protect the sealing part structure.

[0032] In this invention, several barbed protrusions 61 are spaced vertically on both sides of the plug plate 4. During installation, the plug plate 4 is inserted into the mounting groove. Due to their elastic deformation, the barbed protrusions 61 return to their original shape after entering the mounting groove and are stuck against the inner wall of the mounting groove. During disassembly, the friction between the barbed protrusions and the mounting groove must be overcome, and tools can be used to assist in disassembly. The barbed protrusions 61 have a simple structure, are easy to manufacture, and can adapt to mounting grooves with different roughness, thereby improving the applicability and installation stability of the sealing strip.

[0033] The seal 6 can be replaced with different shapes to meet different sealing requirements.

[0034] For example, the first shape of seal 6 is a semi-circular cross-section structure; the semi-circular cross-section seal can better fit the sealing surface with the arc surface, reduce the sealing gap and improve the sealing effect; when the semi-circular structure is squeezed, the force is uniform and it can still maintain good sealing performance after deformation, and the arc transition is not easy to wear the sealing surface, thus extending the service life of the seal and the sealed object.

[0035] The second shape of the seal 6 is a triangular cross-section with rounded corners at the top. The triangular structure has good support and can generate a large rebound force when compressed, ensuring that the seal fits tightly with the sealing surface.

[0036] The third shape of the seal 6 is an M-shaped cross-section. The M-shaped cross-section seal has multiple sealing contact points, which can form multiple sealing defenses and significantly improve sealing performance. When the M-shaped structure is compressed, multiple bending parts can undergo elastic deformation to adapt to sealing surfaces of different shapes and enhance the adaptability of the sealing strip to complex sealing scenarios.

[0037] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
