Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring technology, specifically a quick-assembly wear-resistant rubber sealing ring for automobiles. Background Technology

[0002] A sealing ring is a component that prevents fluid or solid particles from leaking between adjacent mating surfaces and prevents external impurities such as dust and moisture from entering the interior of machinery and equipment.

[0003] Automotive rubber seals are sealing components used in automobiles. They are mainly made of rubber and are used in large quantities in various locations such as car doors, hydraulic cylinders, and suspension systems. Rubber seals are known for their excellent elasticity, wear resistance, and corrosion resistance. Precisely designed rubber seals can maintain stable sealing performance under various temperature and pressure conditions. In addition, the wear resistance and corrosion resistance of the rubber material itself ensure the long-term stable operation of the seals in harsh environments, so as to achieve good waterproof, dustproof, sound insulation, and vibration reduction effects.

[0004] There are various shapes and types of automotive sealing rings, including O-rings, squares, and irregular shapes. Among them, square and irregular-shaped sealing rings are mainly used for fixing and sealing automotive assembly parts. If the original assembly parts need to be re-grinded during automotive repair, multiple sealing rings need to be stacked after grinding to compensate for the dimensional errors caused by grinding. However, existing square and irregular-shaped sealing rings are prone to misalignment when stacked, resulting in long installation, assembly, and debugging times and a high risk of assembly misalignment. Based on this, a quick-assembly automotive wear-resistant rubber sealing ring is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-assembly wear-resistant rubber sealing ring for automobiles in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly automotive wear-resistant rubber sealing ring, comprising a sealing ring body, wherein a corrugated inner sheet is fixed at the inner periphery of the sealing ring body, the horizontal cross-section of the corrugated inner sheet is an "M" shaped structure, and two stacked sealing ring bodies are engaged with the upper surface of the lower corrugated inner sheet by the lower surface of the upper corrugated inner sheet, thereby achieving horizontal and longitudinal positioning of the two stacked sealing ring bodies.

[0007] As a further embodiment of this utility model: the two corrugated inner sheets that are vertically diagonally distributed do not contact each other, and a filling corner piece is fixed at the inner corner of the sealing ring body, the filling corner piece being distributed between the two vertically diagonally distributed corrugated inner sheets.

[0008] As a further improvement of this utility model, the outer wall trajectory of the sealing ring body, the inner area trajectory composed of the four corrugated inner pieces and the four filling corner pieces are set according to the shape of the assembly position.

[0009] As a further improvement of this utility model: the top of the sealing ring body is provided with a number of through holes along the shape trajectory of the sealing ring body, and the position and number of the through holes are set according to the position and number of the fixing holes at the assembly position.

[0010] As a further improvement of this utility model, the sealing ring body, the corrugated inner sheet, the through hole, and the filling corner sheet are integrally formed by rubber injection molding.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] By setting corrugated inner plates, when two sealing ring bodies are stacked one on top of the other, the horizontal and vertical limits of the two sealing ring bodies can be achieved through the interlocking of the upper and lower corrugated plates. This can prevent misalignment between the stacked sealing ring bodies, ensuring the sealing performance of the assembly and improving the overall work efficiency of automotive repair.

[0017] 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.

[0018] Please see Figures 1 to 3In this embodiment of the present invention, a quick-assembly automotive wear-resistant rubber sealing ring includes a sealing ring body 1. A corrugated inner sheet 2 is fixed at the inner periphery of the sealing ring body 1. The horizontal cross-section of the corrugated inner sheet 2 is an "M" shaped structure. Two stacked sealing ring bodies 1 are engaged with the upper surface of the lower corrugated inner sheet 2 by the lower surface of the upper corrugated inner sheet 2, which is used to limit the horizontal and vertical movement of the two stacked sealing ring bodies 1.

[0019] Two corrugated inner sheets 2 are distributed diagonally and do not contact each other, and a filling corner piece 4 is fixed at the inner corner of the sealing ring body 1. The filling corner piece 4 is distributed between the two corrugated inner sheets 2 that are distributed diagonally.

[0020] The outer wall trajectory of the sealing ring body 1, the inner area trajectory composed of four corrugated inner pieces 2 and four filling corner pieces 4 are set according to the shape of the assembly position;

[0021] Several through holes 3 are provided on the top of the sealing ring body 1 along the shape trajectory of the sealing ring body 1. The position and number of through holes 3 are set according to the position and number of fixing holes at the assembly position.

[0022] In this embodiment, it should be further explained that when a corresponding sealing ring needs to be installed on the car assembly part, an installation groove is formed on its surface edge. The overall shape of the sealing ring body 1, the corrugated inner sheet 2, and the filling corner piece 4 matches the shape of the installation groove on the car assembly part. When the filling corner piece 4 is squeezed and fully unfolded into a sheet structure, the sealing ring body 1, the corrugated inner sheet 2, and the filling corner piece 4 completely fill the installation groove, thereby achieving the assembly sealing operation of the car assembly part.

[0023] During the use of a car, rust may appear on the assembled parts due to rain immersion. During repairs, the rusted areas need to be polished and ground, which can lead to larger gaps in the later assembly. At this time, it is necessary to use multiple sealing rings stacked together. When two sealing ring bodies 1 are stacked one on top of the other, the horizontal and vertical limits of the two sealing ring bodies 1 can be achieved by the interlocking of the upper and lower corrugated plates 2. This can prevent misalignment between the stacked sealing ring bodies 1, which not only ensures the sealing of the assembly, but also improves the overall work efficiency of car repair.

[0024] It should also be noted that through hole 3 is for bolts to pass through in the automotive assembly parts.

[0025] Please refer to this carefully. Figures 1 to 3 The sealing ring body 1, corrugated inner sheet 2, through hole 3, and filling corner sheet 4 are integrally formed by rubber injection molding process.

[0026] In this embodiment: This rubber sealing ring is integrally formed by rubber injection molding, which is the same as the molding process of existing sealing rings. It can improve the production based on the existing sealing ring production process, making it easy to promote and apply.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
