Technical Field
[0001] This utility model relates to the field of automotive engine sealing ring technology, specifically automotive engine sealing rubber O-rings. Background Technology
[0002] Automotive engine seals refer to various sealing elements installed inside the engine, mainly used to prevent leakage of liquids such as engine oil and coolant, and to ensure the sealing between various engine components. These seals are usually made of elastic materials and can maintain a stable working state in high-pressure and high-temperature environments. O-rings are the most common type of seal and are usually used at the interface between the cooler pipe and the engine to ensure the sealing of engine oil and coolant, prevent oil leakage, and maintain the normal operation of the engine.
[0003] When installing automotive engine sealing rubber O-rings, the overall structure lacks good toughness, and the rubber ring lacks corresponding toughness filling structure and deformation buffer chamber, which makes it prone to breakage and damage during use.
[0004] Therefore, we propose a novel automotive engine sealing rubber O-ring to solve the above-mentioned technical problems. Utility Model Content

[0034] Example 1
[0035] This embodiment provides a technical solution: a sealing rubber O-ring for an automotive engine, such as... Figures 1-5 As shown, it includes an engine O-ring housing 1, an O-ring rubber ring groove 2, a wear-resistant rubber ring 4, a convex rubber sheet 3, a central pressure-resistant rubber ring, an inner toughness rubber ring, and a deformation buffer cavity groove 7.
[0036] The engine O-ring housing 1 has an O-ring groove 2 in the center of its interior. The engine O-ring housing 1 fits snugly into a designated position on the car engine through the area of the O-ring groove 2. Wear-resistant rubber rings 4 are installed on both sides of the engine O-ring housing 1, providing wear resistance. A convex rubber strip 3 is installed on the outer circumference of the wear-resistant rubber ring 4, increasing the contact force and effectively preventing slippage during installation. A central pressure-resistant rubber ring is installed in the center of the engine O-ring housing 1. The engine O-ring housing 1... The rubber ring serves as a central reinforcement for toughness. The inner toughness rubber ring is installed on both sides of the central pressure-resistant rubber ring, effectively limiting the position of the central pressure-resistant rubber ring and preventing its movement. The inner toughness rubber ring is located inside the engine O-ring 1, thus effectively strengthening the toughness of the engine O-ring 1. The deformation buffer groove 7 is located between the central pressure-resistant rubber ring, the inner toughness rubber ring, and the engine O-ring 1. Through the area of the deformation buffer groove 7, the central pressure-resistant rubber ring, the inner toughness rubber ring, and the engine O-ring 1 can effectively deform during compression, thus achieving a good toughness deformation effect.
[0037] The engine O-ring housing 1 is O-shaped and hollow inside, which can effectively wrap and position it for use.
[0038] The deformation buffer cavity 7 is located at the corner of the central pressure-resistant rubber ring and the inner tough rubber ring, so that the central pressure-resistant rubber ring and the inner tough rubber ring can be effectively deformed through the area of the deformation buffer cavity 7 at the four corners.
[0039] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the central pressure-resistant rubber ring includes an intermediate pressure-resistant rubber ring 5. The intermediate pressure-resistant rubber ring 5 has pressure-resistant buffering properties and is resistant to low temperatures. An external wrapping rubber tube 51 is installed around the periphery of the intermediate pressure-resistant rubber ring 5. The intermediate pressure-resistant rubber ring 5 can be effectively wrapped and reinforced by the external wrapping rubber tube 51, which can effectively strengthen the wrapping and positioning. An outer support rubber ring 52 is installed on both sides of the external wrapping rubber tube 51. The external wrapping rubber tube 51 can be effectively clamped and positioned by the outer support rubber rings 52 on both sides. The external wrapping rubber tube 51 is positioned and installed on the inner side of the engine O-ring 1 by the outer support rubber rings 52. The external wrapping rubber tube 51 can be stably placed in the inner side of the engine O-ring 1 by the outer support rubber rings 52.
[0040] The central anti-compression rubber ring is made of butyl rubber, which provides excellent pressure resistance and cushioning, as well as good toughness, thus preventing crushing and damage.
[0041] In use, the engine O-ring 1, through the area of the O-ring groove 2, can be fitted onto the designated position on the car engine. The two sides of the engine O-ring 1 are protected by wear-resistant rubber rings 4, and the convex rubber sheet 3 is installed on the outer circumference of the wear-resistant rubber ring 4. The wear-resistant rubber ring 4, through the outer convex rubber sheet 3, increases the contact force, thus effectively preventing slippage during installation. The engine O-ring 1 is reinforced by the central anti-compression rubber ring, and the inner toughness rubber ring effectively limits the position of the central anti-compression rubber ring, preventing its movement. During compression, through the area of the deformation buffer groove 7, the central anti-compression rubber ring, the inner toughness rubber ring, and the engine O-ring 1 can be effectively deformed, thus achieving a good toughness deformation effect.
[0042] Example 2
[0043] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 1-4 As shown, to further better realize this utility model, the following configuration is specifically adopted: the inner tough rubber ring includes an inner rubber sleeve 6, and a toughness wire groove 62 is opened on the inner side of the inner rubber sleeve 6. The inner rubber sleeve 6 can be effectively limited through the area of the toughness wire groove 62. A reinforcing toughness wire 61 is installed on the inner side of the toughness wire groove 62 on the inner rubber sleeve 6. The inner rubber sleeve 6 has good elastic toughness through the metal toughness of the reinforcing toughness wire 61, thus avoiding deformation and breakage caused by compressive deformation.
[0044] The wear-resistant rubber ring 4 and the convex rubber sheet 3 are made of nitrile rubber, which gives them excellent wear resistance.
[0045] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
