Description
Technical Field
[0001] The utility model relates to the technical field of sealing rings, in particular to an anti-deformation sealing ring for an engine. Background Art
[0002] The sealing rings of automobile engines are key components used to ensure close contact between various components inside the engine and prevent leakage of fluids (such as engine oil, coolant, etc.). These sealing rings play a crucial role in automobile engines, ensuring the normal operation and performance of the engine. According to different application scenarios and requirements, automobile engine sealing rings can be divided into various types, and each type has its specific materials and characteristics to adapt to different working conditions and media. Different types of sealing rings also have specific requirements in terms of design and installation to ensure their effectiveness and durability. The control of the production process is also a key link in ensuring the quality of the sealing rings. Strict quality control is required for each step, including material formulation, mixing, filtration, and molding and vulcanization. However, for the common engine sealing rings on the market, with the increase of service time, aging, and external factors, the sealing rings are prone to deformation, resulting in a decrease in sealing strength. And during the continuous sealing process, if the internal pressure at the installation position is relatively high, oil leakage is likely to occur. Summary of the Utility Model
[0003] An embodiment of the present disclosure relates to an anti-deformation sealing ring for an engine. When the sealing ring body is installed and used, the inner part structure made of metal material and the support ring are installed inside the sealing ring body for support. After the sealing ring body is pressurized, the support rod structure is inside the sealing ring body for support, reducing the probability of longitudinal deformation. At the same time, the outside of the support ring is connected to the outer ring structure through the force-bearing block structure, making it inside the sealing ring body to improve the support strength and anti-extrusion effect, avoiding deformation of the sealing ring body, and effectively improving the service life.
[0004] In the first aspect of the present disclosure, an anti-deformation sealing ring for an engine is provided, specifically including: a sealing ring body; the sealing ring body is made of rubber material, and the cross-section of the sealing ring body is an L-shaped structure. A flow groove is opened at the inner angle position at the top of the sealing ring body, and the flow groove is an arc-shaped structure. The inner side of the flow groove is communicated with the inner groove, and the circular inner groove is opened at the upper position inside the sealing ring body; an inner part structure; the inner part structure made of elastic metal material is fixedly arranged inside the sealing ring body. Uniformly arranged support rod structures are fixed on the outer side of the inner part structure. A ring-shaped and uniformly arranged force-bearing block structure is fixed at the top of the inner part structure through a support ring. Both sides of the force-bearing block structure are inclined structures, and the outside of the force-bearing block structure is connected to the outer ring structure.
[0005] In at least some embodiments, support balls arranged in a ring and evenly are fixed at the inner end of the inner groove. A retaining ring assembly with a circular ring structure is provided at the top end of the sealing ring body, and the top end of the retaining ring assembly is of an arc structure; a barrier groove with a circular ring structure is formed at the top end of the sealing ring body, and a barrier ring assembly is fixed inside the barrier groove. The material of the barrier ring assembly is the same as that of the sealing ring body, and both sides of the barrier ring assembly are of an inclined structure; an outer groove is formed on the outer side of the sealing ring body, and both the upper and lower sides of the outer groove are of an inclined structure. An auxiliary groove is provided inside the outer groove, and the auxiliary groove with a circular ring structure is formed inside the sealing ring body.
[0006] In at least some embodiments, a support ring is fixed at the inner top end of the inner part structure. The support ring made of metal and the inner part structure are built and fixed together inside the sealing ring body; uniformly arranged auxiliary rods are fixed at the top end of the inner part structure, and the top ends of the auxiliary rods are connected to the outer ring structure to support the outer ring structure; a positioning structure arranged in a ring and evenly is fixed inside the support ring, and the positioning structure with an arc structure is embedded and fixed inside the sealing ring body, and an arc-shaped through groove is formed through the inside of the positioning structure.
[0007] The utility model provides an engine anti-deformation sealing ring, which has the following beneficial effects:
[0008] When the sealing ring body is installed and used, the inner part structure made of metal and the support ring are installed together inside the sealing ring body for support. After the sealing ring body is pressed, the support rod structure is inside the sealing ring body for support, reducing the probability of longitudinal deformation. At the same time, the outside of the support ring is connected to the outer ring structure through the force-bearing block structure, making it inside the sealing ring body to improve the support strength and anti-extrusion effect, avoiding deformation of the sealing ring body and effectively improving the service life.
[0009] When oil leakage occurs during the use of the sealing ring body, the oil liquid enters the inside of the flow-through groove through the upper part of the sealing ring body. Since the inside of the flow-through groove is of an arc structure, it controls the guiding and flowing of the oil liquid. Since the support balls are inside the inner groove for support, after the sealing ring body is pressed, the inner groove will not be closed. After the oil liquid enters the inner groove by means of pressure, with the help of the pressure and the elasticity of the sealing ring body, the top end of the sealing ring body is pushed to expand and expand slightly, improving the sealing effect and the fitting effect with the installation position and reducing the probability of oil leakage.

[0023] Embodiment 1: Please refer to Figures 1 to 6 :
[0024] The utility model provides an engine anti-deformation sealing ring, which comprises: a sealing ring body 1; the sealing ring body 1 is made of rubber, and the cross section of the sealing ring body 1 is an L-shaped structure. A flow-through groove 101 is arranged at the inner included angle position at the top end of the sealing ring body 1, so that when pressure causes oil to seep out, it enters the inside of the flow-through groove 101. The flow-through groove 101 is an arc-shaped structure, and the inner side of the flow-through groove 101 is communicated with an inner groove 102. The annular inner groove 102 is arranged at a position close to the upper part inside the sealing ring body 1, so that after pressure causes oil to enter the inner groove 102, the top end of the sealing ring body 1 is slightly expanded, improving the sealing effect and reducing the probability of oil leakage; an inner part structure 2; the inner part structure 2 made of elastic metal is fixedly arranged inside the sealing ring body 1. Uniformly arranged support rod structures 202 are fixed on the outer side of the inner part structure 2 to support inside the sealing ring body 1, reducing the probability of longitudinal deformation. The top end of the inner part structure 2 is fixed with annularly and uniformly arranged force-bearing block structures 204 through a support ring 201. The two sides of the force-bearing block structures 204 are inclined structures, and the outside of the force-bearing block structures 204 is connected with an outer ring structure 205 to support at the top end of the inner part structure 2, improving the support effect and preventing the sealing ring body 1 from deforming after continuous force application, affecting the service life.
[0025] In the embodiment of the present disclosure, as Figure 3 with Figure 4 shown, annularly and uniformly arranged support balls 103 are fixed at the inner end of the inner groove 102 to support inside the inner groove 102, preventing the inner groove 102 from being sealed after the sealing ring body 1 is pressed. A circular ring-shaped retaining ring assembly 104 is arranged at the top end of the sealing ring body 1, and the top end of the retaining ring assembly 104 is an arc-shaped structure for contacting the installation position to improve the sealing effect; a circular ring-shaped blocking groove 105 is arranged at the top end of the sealing ring body 1 to block the seepage of oil. A blocking ring assembly 106 is fixed inside the blocking groove 105. The material of the blocking ring assembly 106 is the same as that of the sealing ring body 1. The two sides of the blocking ring assembly 106 are inclined structures, improving the oil blocking effect and the oil blocking strength; an outer groove 107 is arranged on the outer side of the sealing ring body 1. The upper and lower sides of the outer groove 107 are inclined structures, and an auxiliary groove 108 is arranged inside the outer groove 107. The circular ring-shaped auxiliary groove 108 is arranged inside the sealing ring body 1. The outer groove 107 and the auxiliary groove 108 improve the elasticity of the sealing ring body 1, enabling the sealing ring body 1 to be better squeezed and sealed.
[0026] In the embodiment of the present disclosure, as Figure 5 with Figure 6As shown in the figure, a support ring 201 is fixed to the inner top end of the inner component structure 2. The support ring 201 made of metal and the inner component structure 2 are built and fixed together inside the sealing ring body 1 to improve the anti-deformation strength together. A uniformly arranged auxiliary rod 203 is fixed to the top end of the inner component structure 2. The top end of the auxiliary rod 203 is connected to the outer ring structure 205 and supports the outer ring structure 205 to improve the support effect. A ring-shaped and uniformly arranged positioning structure 206 is fixed to the inner side of the support ring 201. The arc-shaped positioning structure 206 is embedded and fixed inside the sealing ring body 1. An arc-shaped through groove 207 is formed through the inside of the positioning structure 206 to improve the positioning effect inside the sealing ring body 1, so that the inner component structure 2 and the support ring 201 are not easily displaced inside the sealing ring body 1.
[0027] The working principle of this embodiment: The inner component structure 2 and the support ring 201 are used together inside the sealing ring body 1. When the sealing ring body 1 needs to be installed inside an automobile engine for use, the installation position of the sealing ring body 1 can be controlled. When the sealing ring body 1 is squeezed and sealed, during the use of the sealing ring body 1, the support ring 201 longitudinally supports inside the sealing ring body 1, so that the sealing ring body 1 will not be longitudinally deformed. At the same time, the inner component structure 2 and the support ring 201 cooperate with the force receiving block structure 204 and the outer ring structure 205 to generate a lateral support force, avoiding deformation of the sealing ring body 1 after continuous stress, effectively improving the service life. When oil leakage occurs due to pressure during the use of the sealing ring body 1, the oil enters the inside of the flow through groove 101, and then enters the inside of the inner groove 102 by means of pressure, transmitting the pressure to the inner groove 102, causing the top end of the sealing ring body 1 to be slightly expanded by the force, automatically improving the sealing effect and reducing the probability of oil leakage.
