Description

Technical Field

[0001] This utility model relates to the field of engine cover plug technology, specifically to a self-skinning engine cover plug with a multi-directional sealing lip. Background Technology

[0002] Engine cover plugs, as critical sealing components in engine systems, are primarily used to seal oil passages, water passages, and process orifices, preventing lubricant and coolant leakage and isolating external impurities. Their performance directly affects the reliability and durability of the engine. Self-skinning materials (such as polyurethane self-skinning materials), due to their dense surface and internal foaming, possess both hardness and elasticity, and are increasingly being used in plug manufacturing to improve wear resistance and cushioning. However, traditional self-skinning plugs still mostly have a unidirectional sealing lip design, which is insufficient for multidirectional sealing under complex operating conditions, making it difficult to meet the higher requirements of engine sealing reliability.

[0003] However, current self-skinning engine cover plugs with multi-directional sealing lips often have dimensional deviations, insufficient roundness, or uneven inner walls and surfaces in their engine cover casting holes. Traditional plugs are prone to tilting due to uneven force on one side, leading to poor sealing. Furthermore, most lips on the market are unidirectional fixed structures, resulting in a single sealing effect and easy leakage. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art by providing a self-skinning engine cover plug with a multi-directional sealing lip.

[0005] The specific technical solution is as follows:

[0006] A self-skinning engine hood plug with a multi-directional sealing lip includes: an engine hood cover and a multi-directional lip plug assembly. The multi-directional lip plug assembly is inserted into a hole provided in the engine hood cover. The multi-directional lip plug assembly includes a plug block, which is inserted into the hole. One end of the upper surface of the plug block is provided with a retaining groove, and the edge of the upper surface of the plug block is provided with a spacer ring.

[0007] As a preferred embodiment of this utility model, an abutment block is installed on one side of the outer surface of the machine cover. The abutment block is semi-circular in shape, and an adaptation block is installed on one side of the rubber plug.

[0008] As a preferred embodiment of this utility model, a straightening plate is provided on one side of the adapting block along the length direction, and the other end of the straightening plate is flush with the abutting block. When the glue block is inserted into the hole, it can adapt to the irregular shape of the hole by the compression deformation of the straightening plate and the abutting block.

[0009] As a preferred embodiment of this utility model, the lower half of the plug block is provided with stabilizing plates on both sides, and soft rubber balls are glued to one side of each of the two stabilizing plates. The two stabilizing plates are arranged in opposite directions and staggered vertically. The stabilizing plates are made of polyurethane self-skinning material.

[0010] As a preferred embodiment of this utility model, the lower surface of the glue block is connected to a lip ring, which can be inserted into the hole through the glue block, and after extending out of the hole through its end, it flips to form a circular ring structure.

[0011] As a preferred embodiment of this utility model, adhesive rings are respectively bonded to both sides of the outer surface of the lip ring. The adhesive rings are made of high temperature resistant pressure-sensitive adhesive material. The adhesive rings can rotate and adhere to one side of the inner wall upper surface of the machine cover along with the lip ring.

[0012] This utility model has the following beneficial effects:

[0013] 1. The self-skinning engine cover plug with multi-directional sealing lips provided by this utility model effectively blocks external impurities from entering through gaps through spacers, protecting internal components. The adapting block and the positioning plate fit the inner wall of irregular holes with elastic deformation, and together with the abutment block, they form a stable support, which can avoid tilting or one-sided lifting caused by hole shape deviation, ensuring that the plug block is subjected to balanced force and greatly enhancing the installation firmness. Then, the stabilizing plate and the soft rubber ball are tightly fitted to the inner wall through compression deformation, and combined with the adhesive ring after the lip ring is flipped, a multi-directional sealing structure is formed, which can effectively prevent leakage and resist loosening caused by long-term vibration.

[0027] Example 1

[0028] The self-skinning engine cover plug with multi-directional sealing lips provided in this embodiment, such as... Figures 1-6 As shown, the device includes: a hood cover 1 and a multi-directional lip plug assembly 2. The multi-directional lip plug assembly 2 is inserted into a hole 101 provided in the hood cover 1. The multi-directional lip plug assembly 2 includes a plug block 201, which is inserted into the hole 101. One end of the upper surface of the plug block 201 has a retaining groove 202, and the edge of the upper surface of the plug block 201 has a spacer ring 204. An abutment block 205 is installed on one side of the outer surface of the hood cover 1. The abutment block 205 is semi-circular. An adaptation block 206 is installed on one side of the plug block 201. A straightening plate 207 is provided along the length direction on one side of the adaptation block 206. The other end of the straightening plate 207 is flush with the abutment block 205. When the plug block 201 is inserted into the hole 101, it can adapt to the irregular shape of the hole 101 by being squeezed and deformed by the straightening plate 207 and the abutment block 205.

[0029] Through the design of the multi-directional lip plug assembly 2, the plug block 201, and the spacer ring 204, the plug block 201 in the multi-directional lip plug assembly 2 is inserted into the hole 101 of the cover 1. The groove 202 on its surface facilitates removal or insertion. Then, the spacer ring 204 can further prevent external impurities from entering the gap between the plug block 201 and the hole 101 from the top. During the insertion process, the adaptation block 206 and the positioning plate 207 on the upper surface of the plug block 201 fit into the hole 101 through their own elasticity. Through compression deformation, it adapts to the irregular shape of the inner wall. Then, it cooperates with the abutment block 205 to form effective support, preventing tilting or displacement caused by the irregular shape of the hole 101. This ensures that the plug block 201 is evenly stressed in the hole 101, avoiding unilateral lifting or tilting due to the irregular shape of the hole 101, and improving the installation stability of the plug block 201.

[0030] Both the adaptation block 206 and the orthopedic plate 207 are made of polyurethane self-skinning material, which has moderate elasticity and structural strength.

[0031] Example 2

[0032] The self-skinning engine cover plug with multi-directional sealing lips provided in this embodiment, such as... Figures 3-6As shown, the device includes: stabilizing plates 208 on both sides of the lower half of the plug block 201; soft rubber balls 210 are adhered to one side of each of the two stabilizing plates 208; the two stabilizing plates 208 are arranged in opposite directions and staggered vertically; the stabilizing plates 208 are made of polyurethane self-skinning material. A lip ring 203 is connected to the lower surface of the plug block 201; the lip ring 203 can be inserted into the hole 101 through the plug block 201, and after extending out of the hole 101 at its end, it flips to form a ring structure. Adhesive rings 209 are adhered to both sides of the outer surface of the lip ring 203; the adhesive rings 209 are made of high-temperature pressure-sensitive adhesive material; the adhesive rings 209 can flip and adhere to one side of the inner wall upper surface of the cover 1 along with the lip ring 203.

[0033] Through the design of the stabilizing plate 208, soft rubber ball 210, and lip ring 203, the rubber plug 201 is inserted into the hole 101 in an inclined state. During the insertion process, the soft rubber ball 210 on the surface of the stabilizing plate 208 is squeezed and deformed. After the insertion is completed, the soft rubber ball 210 and the stabilizing plate 208 made of polyurethane self-skin material can effectively adhere to the inner wall of the hole 101 to increase stability. Then, by flipping the lip ring 203 on the lower surface to form a ring, the adhesive ring 209 on the surface also flips and adheres to one end of the upper surface of the inner wall of the cover 1, further improving the insertion stability, thereby forming a multi-directional seal to prevent leakage and avoid loosening caused by vibration during long-term use.

[0034] In summary, the self-skinning engine hood plug with multi-directional sealing lips provided in this embodiment has the following advantages: the adapting block 206 and the positioning plate 207 fit into the hole 101 through their own elasticity, adapt to the irregular shape of the inner wall through compression deformation, and then form effective support by cooperating with the abutment block 205 to prevent tilting or displacement caused by the irregular shape of the hole 101. The lip ring 203 further improves the insertion stability, thereby forming a multi-directional seal to prevent leakage.

[0035] In use, the rubber plug 201 is inserted into the hole 101 at an angle. The groove 202 on its surface facilitates removal or insertion. The spacer 204 further prevents external impurities from entering the gap between the rubber plug 201 and the hole 101. During insertion, the adapting block 206 and the positioning plate 207 on the upper surface of the rubber plug 201 elastically conform to the hole 101, adapting to the irregular shape of the inner wall through compression deformation. It then cooperates with the abutment block 205 to form... Effective support is provided. During the insertion process, the soft rubber balls 210 on the surface of the stabilizing plate 208 are compressed and deformed. After the insertion is completed, the soft rubber balls 210 and the stabilizing plate 208 made of polyurethane self-skin material can effectively adhere to the inner wall of the hole 101 to increase stability. Then, by flipping the lip ring 203 on the lower surface to form a ring, the adhesive ring 209 on the surface also flips and adheres to one end of the upper surface of the inner wall of the cover 1, further improving the insertion stability and thus forming a multi-directional seal to prevent leakage.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
