Description

Technical Field

[0001] This utility model relates to the field of automotive sealing gasket technology, specifically a splicing type automotive metal sealing gasket. Background Technology

[0002] The oil pan gasket is a key component located at the bottom of the engine, used to seal the crankcase and store lubricating oil. Its core function is to prevent oil leakage. Depending on its location, it is mainly divided into two types: housing gasket and bolt gasket. Bolt gaskets are mainly used in conjunction with the oil pan fastening bolts to prevent oil leakage at the bolt connection.

[0003] An investigation revealed that a utility model patent discloses an automotive oil pan sealing gasket (publication number: CN215861657U), comprising a gasket body, a filler, and a bolt. The gasket body contains the filler and is movably fitted onto the bolt. After the gasket body is movably fitted onto the bolt, it is placed on the automotive oil pan for sealing. The gasket body includes a gasket 1 and a gasket 2. The gasket 2 is fixedly disposed on the inner side of the gasket 1. Both gaskets 1 and 2 have a uniform circular structure and are made of carbon steel. The gaskets 1 and 2 are combined to form the gasket body, and both gaskets 1 and 2 contain the filler, which is a non-asbestos gasket. The gasket body is fitted onto the bolt, and then the bolt is screwed onto the automotive oil pan to achieve torque sealing. The gasket body 1 provides effective sealing. This automotive oil pan sealing gasket has the advantages of simple and practical structure, easy installation and replacement of gaskets, and high-efficiency sealing.

[0004] The aforementioned patent achieves bolt sealing through the auxiliary cooperation of gasket one and gasket two. However, in actual use, due to its integral structural design, the entire structure needs to be replaced after partial seal damage, which increases subsequent maintenance costs. At the same time, due to the poor flexible deformation performance of the metal gasket surface, it is impossible to fully compress and contact the sealing surface. There will be a certain gap between the gasket surface and the two sides of the compression seal, thereby reducing its sealing performance.

[0005] Therefore, this utility model provides a splicing type automotive metal sealing gasket to solve the above problems. Utility Model Content

In addition, by replacing the rubber sleeve individually, the equipment maintenance cost is reduced, and its sealing effect is ensured. At the same time, the auxiliary docking of the sealing ring improves the sealing effect of the sealing gasket in contact with the bolt thread, thereby further improving the sealing performance of the device. Furthermore, the two-sided setting of the sealing sleeve further enhances the compression sealing performance on both sides. Through the flexible contact of the sealing sleeve, the adaptability of its contact surface is improved. Combined with the compression of the large end of the bolt, the sealing performance of the sealing surface is ensured. Attached Figure Description

[0030] 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.

[0031] like Figure 1-5As shown, this utility model provides a splicing type automotive metal sealing gasket, including a positioning ring 1 with positioning holes 11 on its circumference; two sets of sealing components 2, which are respectively distributed on both sides of the positioning ring 1. The sealing components 2 include a fixing ring 21, and a sealing sleeve 24 is wrapped around the outside of the fixing ring 21; and a bolt 3, in which the combination of the positioning ring 1 and the sealing components 2 is fitted onto the threads of the bolt 3. The sealing components 2 are spliced ​​and fixed to the positioning ring 1, so that the sealing components 2 can be disassembled and replaced. This allows for targeted replacement of parts when the sealing performance of the device decreases in the later stages of use, thereby avoiding the cost increase caused by replacing the entire device.

[0032] Furthermore, a limiting ring 22 is fixedly connected to one side of the fixing ring 21, and a plug-in post 23 is fixedly connected to the other side of the limiting ring 22. The plug-in post 23 is inserted into the inside of the positioning hole 11. The plug-in posts 23 of the two sets of sealing components 2 are staggered and inserted into the inside of the positioning hole 11. The height of the plug-in post 23 is not greater than the depth of the positioning hole 11, and the diameter of the positioning hole 11 is equal to the outer diameter of the plug-in post 23. The plug-in connection between the plug-in post 23 and the positioning hole 11 makes the splicing method of the sealing components 2 on both sides simpler and more convenient.

[0033] Furthermore, the outer diameter of the positioning ring 1 is equal to the outer diameter of the sealing sleeve 24, and the number of openings in the positioning hole 11 is twice the number of insertion pins 23.

[0034] Furthermore, the thickness of the limiting ring 22 is equal to the thickness of the sealing sleeve 24, and an installation ring adapted to the limiting ring 22 is provided on the side of the sealing sleeve 24 that is close to each other. The installation ring of the sealing sleeve 24 allows the sealing sleeve 24 to be wrapped around the outside of the fixing ring 21, further realizing the individual disassembly and assembly of the sealing sleeve 24. This allows the sealing sleeve 24 to be individually disassembled and replaced when it ages and breaks, further reducing the subsequent maintenance cost of the device.

[0035] Furthermore, a sealing ring 25 is fixedly connected to the inner wall of the sealing sleeve 24, and the outer diameter of the sealing ring 25 is equal to the diameter of the central hole of the positioning ring 1. The sealing ring 25 has a protruding structure on the side facing the mounting ring of the sealing sleeve 24, and the height of the protruding structure is equal to half the thickness of the positioning ring 1. While the sealing components 2 on both sides are installed and fixed, the outer wall of the bolt 3 can be sealed and wrapped through the contact of the sealing ring 25. After the two sets of sealing components 2 are connected, the sealing ring 25 is sealed and connected to the inner wall of the central hole of the positioning ring 1. The inner wall of the sealing ring 25 wraps around the outer wall of the thread of the bolt 3. Furthermore, the compression of the sealing component 2 during the installation of the bolt 3 causes the sealing ring 25 to seal and compress the thread of the bolt 3, thereby further improving its sealing performance.

[0036] Furthermore, the positioning ring 1, the fixing ring 21, and the limiting ring 22 are all circular ring structures, and the positioning ring 1, the fixing ring 21, the limiting ring 22, and the plug-in post 23 are all made of carbon steel.

[0037] Furthermore, the sealing sleeve 24 and the sealing ring 25 are an integral structure, and both the sealing sleeve 24 and the sealing ring 25 are made of rubber. Through the design of the rubber material, they can deform under pressure, thereby improving the sealing effect of the contact surface of the sealing sleeve 24.

[0038] Working principle: First, the sealing sleeve 24 is wrapped and fixed on the outside of the fixing ring 21. Then, the sealing components 2 on both sides of the positioning ring 1 are installed and fixed by inserting the plug post 23 into the positioning hole 11. Then, the device is sleeved on the outside of the bolt 3. Under the installation of the bolt 3, the sealing of the connection part is completed by squeezing the sealing components 2.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
