Description

Technical Field

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

[0002] In the automobile manufacturing process, the sealing performance of a vehicle directly affects its quality. Sealing strips are an important component in the sealing process, and their sealing and stability performance plays a decisive role in the quality, safety, and service life of the product. With the rapid development of technology and the continuous improvement of people's requirements for product quality, the shortcomings of traditional sealing strips in terms of performance have become increasingly prominent. Traditional sealing strips have a simple structure, poor sealing effect between the sealing strip and the connecting parts, and moisture easily accumulates between the sealing strip and the connecting parts after long-term use, resulting in poor performance. This has prompted the research and development and application of high-sealing and stable sealing strips.

[0003] To address the above deficiencies, the existing technology (Chinese patent with publication number CN206406462U and publication date of August 15, 2017) provides a high-sealing polypropylene sealing strip. This sealing strip is made by connecting two polypropylene strips with a rubber strip. Under the action of the rubber strip, the two polypropylene strips can be stably connected together, ensuring its strength. Compared with a single polypropylene sealing strip, it has higher strength and higher flexibility, which can effectively improve sealing performance and stability.

[0004] The above solution improves sealing stability by using mutually adhesive sealing strips, but the sealing strips are still simple strips in shape, which are not good for sealing the joints and for the stability of the connection. During use, under long-term displacement, the gaps are easy to move, which will reduce the sealing performance. At the same time, the sealing performance will also decrease under the influence of the external environment. Utility Model Content

[0005] The purpose of this invention is to provide a robust sealing strip with high sealing performance to solve the problems mentioned in the background art, such as the poor sealing and connection stability of existing sealing strips during use, which reduces the sealing performance and also causes the sealing performance to decline under the influence of the external environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing, stable sealing strip, including a sealing lip, a sealing sheet integrally installed below the sealing lip, and a sealing inner buckle integrally connected to the bottom of the sealing sheet;

[0007] Anti-detachment strips are symmetrically arranged at equal intervals on both sides of the sealing sheet;

[0008] The bottom two sides of the sealing lip are symmetrically fixed with first sealing edges, and the top two sides of the sealing inner buckle are symmetrically provided with second sealing edges.

[0009] The sealing sheet has a reinforcing core inside, and the inner sealing buckle has elastic strips at equal intervals inside.

[0010] Furthermore, the sealing lip is configured as an arc-shaped structure, the sealing sheet is configured as a rectangular structure, and the sealing inner buckle is configured as a long strip structure. The sealing lip, sealing sheet, and sealing inner buckle constitute a complete sealing strip.

[0011] Furthermore, the sealing lip is wide and soft, mainly used to initially block dust and large particles of impurities; the middle sealing piece is short and more elastic, responsible for isolating air and fine dust; the innermost sealing buckle is directly and tightly fitted to the sealing surface to prevent the penetration of gas and liquid.

[0012] Furthermore, the anti-detachment strip is configured as a triangular structure, and the anti-detachment strip is distributed in a barb shape on both sides of the sealing sheet.

[0013] Furthermore, the first sealing edge and the second sealing edge are of equal length, and the first sealing edge and the second sealing edge reinforce the seal at the edge.

[0014] Furthermore, the reinforcing core inside the sealing sheet and the elastic strip inside the sealing buckle are respectively configured as strip-shaped and cylindrical structures.

[0015] Furthermore, both the reinforcing core and the elastic strip are made of carbon fiber reinforced plastic, and the sealing strip increases its overall strength through the reinforcing core and the elastic strip, and can also provide uniform rebound force when compressed, ensuring the stability of the sealing performance.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This high-sealing, robust sealing strip, through its double-layer sealing structure on the inner and outer sides, provides better sealing at the joints during use, and the reinforcing components enhance the overall stability and deformation resistance of the sealing strip.

[0018] Furthermore, the outermost sealing lip is wider and softer, mainly used to initially block dust and large particles of impurities; the middle sealing piece is slightly shorter and more elastic, responsible for isolating air and fine dust; the innermost sealing buckle is directly and tightly fitted to the sealing surface to prevent the penetration of gas and liquid.

[0019] Furthermore, the sealing strip and the inner sealing buckle are equipped with a reinforcing core and an elastic strip, which are made of high-strength carbon fiber reinforced plastic. This not only increases the overall strength of the sealing strip and improves the stability of the installation, but also provides uniform rebound force when compressed, ensuring the stability of the sealing performance.

[0020] Furthermore, the anti-loosening strip can increase the reverse resistance of the seal connection, preventing loosening due to movement during use. Attached Figure Description

[0030] In use, a unique triple-seal structure is employed. The outermost sealing lip 1 is wider and softer, primarily used to initially block dust and large particles of impurities. The middle sealing plate 2 is slightly shorter and more elastic, responsible for isolating air and fine dust. The innermost sealing buckle 3 directly and tightly fits the sealing surface, preventing the penetration of gas and liquid. Meanwhile, a reinforcing core 7 and an elastic strip 8, made of high-strength carbon fiber reinforced plastic, are set inside the sealing plate 2 and the sealing buckle 3. This not only increases the overall strength of the sealing strip and improves the stability of the installation, but also provides uniform rebound force when compressed, ensuring the stability of the sealing performance.

The sealing lip 1, the sealing plate 2, and the sealing inner buckle 3 constitute a complete sealing strip. The sealing lip 1 is wide and soft, mainly used to initially block dust and large particles of impurities; the middle sealing plate 2 is short and more elastic, responsible for isolating air and fine dust; the innermost sealing inner buckle 3 is directly and tightly attached to the sealing surface to prevent the penetration of gas and liquid. The anti-detachment strip 4 is set as a triangular structure, and the anti-detachment strip 4 is distributed in a barb shape on both sides of the sealing plate 2.

[0033] When in use, the sealing lip 1 has the largest coverage area, the sealing piece 2 in the middle fits the sealing seam, the inner sealing buckle 3 is tightly fitted to the inside of the sealing area, and the anti-detachment strip 4 can increase the reverse resistance of the sealing connection and prevent loosening due to movement during use.

The reinforcing core 7 inside the sealing sheet 2 and the elastic strip 8 inside the sealing buckle 3 are respectively set as strip-shaped and cylindrical structures. The reinforcing core 7 and the elastic strip 8 are both made of carbon fiber reinforced plastic. The sealing strip increases the overall strength through the reinforcing core 7 and the elastic strip 8, and can also provide uniform rebound force when squeezed to ensure the stability of the sealing performance.

[0036] When in use, under the action of external force, the reinforcing core 7 in the sealing sheet 2 and the elastic strip 8 in the inner sealing buckle 3 can withstand the external force, preventing the sealing strip from deforming and breaking under force, and enhancing the overall strength of the sealing strip.
