Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive gasket technology, specifically an automotive gasket with pressure resistance and wear resistance. Background Technology
[0002] A gasket is a mechanical seal between two objects, typically used to prevent leakage caused by pressure, corrosion, and natural thermal expansion and contraction of pipelines. Since machined surfaces are never perfect, gaskets can fill irregularities. They are placed between connectors and nuts and are generally flat metal sheets, usually made of metals such as steel, aluminum, copper, nickel, or Monel alloys.
[0003] In the prior art, Chinese Patent Publication No. CN210423383U discloses an automotive gasket, including an inner gasket, a middle gasket, and an outer gasket; the inner gasket has a through hole in the middle; the upper surface of the inner gasket has a first groove; the middle gasket has an inverted "5" shaped cross-section; the middle gasket includes a head and a tail; the head of the middle gasket is engaged in the first groove; the outer gasket has an outer flange and an inner flange at its top; the bottom of the outer gasket has a second protrusion; the second protrusion is attached to the upper side of the tail of the middle gasket; the inner gasket, middle gasket, and outer gasket are all annular structures and are integrally molded by injection molding, resulting in a small volume and simple structure. The integral molding of the inner gasket, middle gasket, and outer gasket reduces labor intensity and improves product quality. The inverted "5" shaped cross-section of the middle gasket facilitates the injection molding of the inner and outer gaskets, thereby strengthening the overall structural strength. The outer flange and inner flange effectively enhance the anti-slip and shock-absorbing effect of the upper surface of the gasket, making it convenient to use.
[0004] Based on the above information, it can be seen that in actual use, the gasket is prone to deformation, cracking, or even breakage due to long-term pressure. At the same time, the outer surface of the gasket is easily worn, resulting in a reduced service life and making it unsuitable for use. Therefore, we have introduced an automotive gasket with pressure resistance and wear resistance. Utility Model Content
[0005] The purpose of this utility model is to provide an automotive gasket with pressure resistance and wear resistance, in order to solve the problems mentioned in the background art, where the gasket is prone to deformation, cracks, or even breakage during actual use due to long-term pressure, and the outer surface of the gasket is easily worn, resulting in a reduced service life and unfavorable use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automotive gasket with pressure resistance and wear resistance, comprising an upper gasket, a lower gasket on the outer wall of the upper gasket, and pressure-resistant mechanisms for preventing deformation of the gasket on the inner walls of the upper and lower gaskets. The pressure-resistant mechanism includes a protrusion fixedly installed on the outer wall of the lower gasket. A shock-absorbing cavity is formed on the outer wall of the upper gasket, and a shock-absorbing block is provided on the inner wall of the shock-absorbing cavity. Reinforcing ribs are provided inside both the upper and lower gaskets, and connecting ribs are fixedly connected to the outer walls of the reinforcing ribs. Wear-resistant mechanisms for preventing wear on the surface of the gasket are provided on the outer walls of both the upper and lower gaskets.
[0007] Furthermore, both the upper and lower pads are designed in a circular shape and are made of alloy steel. The cross-section of the damping cavity is designed in a fan shape, and the depth of the damping cavity is less than the thickness of the upper pad. The damping cavity is set at an equal angle on the outer wall of the upper pad.
[0008] Furthermore, the protrusion is provided corresponding to the damping cavity, and the thickness of the protrusion is less than the depth of the damping cavity, and the outer wall of the protrusion is in contact with the inner wall of the damping cavity. The damping block is provided corresponding to the protrusion, and the damping block is located between the protrusion and the damping cavity.
[0009] Furthermore, the reinforcing ribs are designed in a circular shape, and the reinforcing ribs are arranged at equal intervals inside the upper and lower pads. The outer diameter of the multiple sets of reinforcing ribs gradually increases from the inside to the outside along the pads. The connecting ribs are connected to each set of reinforcing ribs, and the connecting ribs are arranged at equal angles on the outer wall of the reinforcing ribs.
[0010] Furthermore, the wear-resistant mechanism includes a wear-resistant sheet fixedly installed on the outer wall of the upper pad, and the outer wall of the wear-resistant sheet is provided with an anti-slip block and a limiting block, and the outer wall of the upper pad is provided with a limiting groove.
[0011] Furthermore, the wear-resistant pads are symmetrically arranged on the outer walls of the upper and lower pads, and the anti-slip blocks are arranged at equal angles on the outer walls of the wear-resistant pads, with the outer walls of the anti-slip blocks coated with an ultra-high molecular weight polyethylene wear-resistant coating.
[0012] Furthermore, the wear-resistant mechanism includes a wear-resistant sheet fixedly installed on the outer wall of the upper pad, and the outer wall of the wear-resistant sheet is provided with an anti-slip block and a limiting block, and the outer wall of the upper pad is provided with a limiting groove.
[0013] Furthermore, the limiting block is cylindrical in shape and is equidistant from the outer wall of the wear-resistant sheet. The outer walls of the upper and lower pads are provided with limiting grooves corresponding to the limiting block, and the inner wall of the limiting groove is in contact with the outer wall of the limiting block.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This automotive gasket with anti-compression and wear-resistant functions greatly improves its compressive strength by incorporating an anti-compression mechanism. When the gasket is subjected to external pressure, the protrusions on the outer wall of the lower gasket can transmit the pressure to the damping block in the damping cavity. The damping block acts as a buffer, effectively mitigating the direct impact of pressure on the gasket. At the same time, the reinforcing ribs and connecting ribs inside the upper and lower gaskets work together. The reinforcing ribs are circular and evenly distributed. The outer diameter of multiple sets of reinforcing ribs gradually increases from the inside to the outside along the gasket. The connecting ribs connect each set of reinforcing ribs at equal angles, forming a stable internal support structure. This structure can evenly distribute pressure and prevent the gasket from deforming, cracking, or even breaking due to excessive local pressure. This greatly improves the compressive strength and stability of the gasket and extends its service life under high-pressure environments.
[0016] 2. By incorporating wear-resistant mechanisms, the wear resistance of the gasket is significantly enhanced. The wear-resistant plates symmetrically arranged on the outer walls of the upper and lower gaskets, with anti-slip blocks on their outer walls, not only increase the friction between the gasket and the contacting parts, preventing displacement of the gasket during operation, but also feature an ultra-high molecular weight polyethylene wear-resistant coating on the outer walls of the anti-slip blocks, which has excellent wear resistance and can effectively resist wear caused by friction. Simultaneously, the heat dissipation grooves formed between the anti-slip blocks, with their arc-shaped cross-sections and radial penetration through the outer walls of the wear-resistant plates, accelerate heat dissipation during gasket operation, reducing the risk of damage to the gasket caused by frictional heat. Furthermore, the equidistantly spaced limiting blocks on the outer walls of the wear-resistant plates, in conjunction with the limiting grooves on the outer walls of the upper and lower gaskets, further fix the position of the wear-resistant plates, ensuring their stability during long-term use. This comprehensively improves the wear resistance of the gasket and extends its overall service life. Attached Figure Description

[0024] 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.
[0025] Example 1: Please refer to Figure 1-6 This utility model provides the following technical solution: A car gasket with anti-compression and wear-resistant functions, including an upper gasket 1, a lower gasket 2 on the outer wall of the upper gasket 1, and an anti-compression mechanism for preventing deformation of the gasket on the inner walls of the upper gasket 1 and the lower gasket 2. The anti-compression mechanism includes a protrusion 201 fixedly installed on the outer wall of the lower gasket 2. A shock-absorbing cavity 101 is formed on the outer wall of the upper gasket 1, and a shock-absorbing block 4 is provided on the inner wall of the shock-absorbing cavity 101. Reinforcing ribs 5 are provided inside both the upper gasket 1 and the lower gasket 2, and connecting ribs 501 are fixedly connected to the outer wall of the reinforcing ribs 5. Both the upper gasket 1 and the lower gasket 2 are annular in design and are made of alloy steel. The cross-section of the shock-absorbing cavity 101 is fan-shaped. The depth of the upper pad 1 is less than the thickness of the upper pad 1, and the damping cavity 101 is set at equal angles on the outer wall of the upper pad 1. The protrusion 201 is set correspondingly to the damping cavity 101, and the thickness of the protrusion 201 is less than the depth of the damping cavity 101. The outer wall of the protrusion 201 is in contact with the inner wall of the damping cavity 101. The damping block 4 is set correspondingly to the protrusion 201, and the damping block 4 is located between the protrusion 201 and the damping cavity 101. The reinforcing rib 5 is designed in a circular shape, and the reinforcing rib 5 is set at equal intervals inside the upper pad 1 and the lower pad 2. The outer diameter of multiple sets of reinforcing rib 5 gradually increases from the inside to the outside along the pad. The connecting rib 501 is connected to each set of reinforcing rib 5, and the connecting rib 501 is set at equal angles on the outer wall of the reinforcing rib 5.
[0026] When the car gasket is subjected to external pressure, the protrusion 201 on the outer wall of the lower gasket 2, as the direct pressure receiving point, will first transmit the pressure to the damping cavity 101 of the upper gasket 1. The damping block 4 inside the damping cavity 101 then plays a crucial role, effectively absorbing and dispersing some of the pressure due to its excellent elasticity and cushioning performance, thus greatly mitigating the direct impact of the pressure on the gasket body. Simultaneously, the carefully designed reinforcing ribs 5 and connecting ribs 501 inside the upper and lower gaskets 1 and 2 begin to work together. The reinforcing ribs 5 are circular and evenly spaced. This layout... This design ensures that the gasket has a certain compressive strength in all directions. The outer diameter of multiple sets of reinforcing ribs 5 gradually increases from the inside to the outside of the gasket, and the connecting ribs 501 connect each set of reinforcing ribs 5 at equal angles. This creates a stable and uniform internal support network. After the external pressure is initially buffered by the shock-absorbing block 4, it will be evenly distributed to the entire gasket through this support network, avoiding pressure concentration in a certain local area. This effectively prevents the gasket from deforming, cracking, or even breaking due to excessive local pressure, and effectively ensures the compressive strength and stability of the gasket under high pressure.
[0027] Example 2: Based on Example 1, a wear-resistant mechanism is also disclosed, the specific structure of which is as follows: Both the upper gasket 1 and the lower gasket 2 have wear-resistant mechanisms on their outer walls to prevent wear on the gasket surface. The wear-resistant mechanism includes a wear-resistant sheet 3 fixedly installed on the outer wall of the upper gasket 1, and the outer wall of the wear-resistant sheet 3 is provided with an anti-sliding block 301 and a limiting block 303. A limiting groove 6 is formed on the outer wall of the upper gasket 1. The wear-resistant sheets 3 are symmetrically arranged on the outer walls of the upper gasket 1 and the lower gasket 2, and the anti-sliding blocks 301 are arranged at equal angles on the outer wall of the wear-resistant sheets 3. Furthermore, the outer wall of the anti-slip block 301 is coated with an ultra-high molecular weight polyethylene wear-resistant coating, and a heat dissipation groove 302 is formed between the anti-slip blocks 301. The heat dissipation groove 302 has an arc-shaped cross-section and radially penetrates the outer wall of the wear-resistant sheet 3. The limiting block 303 has an overall cylindrical design and is equidistantly arranged on the outer wall of the wear-resistant sheet 3. The outer walls of the upper pad 1 and the lower pad 2 are both provided with limiting grooves 6 corresponding to the limiting blocks 303, and the inner wall of the limiting groove 6 is in contact with the outer wall of the limiting block 303.
[0028] The wear-resistant plates 3, symmetrically installed on the outer walls of the upper gasket 1 and lower gasket 2, form the first line of defense against wear. The anti-slip block 301 on the outer wall of the wear-resistant plate 3, with its special shape and material, increases the friction between the gasket and the contacting parts, allowing the gasket to remain stably in its original position during operation and preventing accelerated wear due to displacement. The ultra-high molecular weight polyethylene wear-resistant coating on the outer wall of the anti-slip block 301, with its excellent wear-resistant properties, effectively copes with the friction generated by the relative movement of the parts, greatly reducing the wear rate of the wear-resistant plate 3 and the gasket as a whole. The heat generated by friction can be quickly dissipated through the heat dissipation groove 302, avoiding the degradation of the gasket material performance due to excessive temperature, thereby reducing the risk of damage to the gasket caused by frictional heat. In addition, the limiting blocks 303 equidistantly arranged on the outer wall of the wear-resistant plate 3 closely cooperate with the limiting grooves 6 opened on the outer walls of the upper gasket 1 and the lower gasket 2, further fixing the wear-resistant plate 3 firmly to the gasket surface, ensuring that the wear-resistant plate 3 remains stable in the long-term, high-frequency friction working environment, comprehensively improving the wear resistance of the gasket, and ultimately extending the overall service life of the gasket.
