[0017] The utility model is further described below in conjunction with the accompanying drawings.
[0018] Reference Figure 1-3As shown, the high-seal engine cover comprises a cover body 1, the outer periphery of the cover body 1 horizontally extends outward to form a first connection part 101, the outer periphery of the engine cylinder body horizontally extends outward to form a second connection part 102, the first connection part 101 and the second connection part 102 form a match, so that the cover body 1 and the engine cylinder body form a match, the bottom end of the first connection part 101 conflicts with the top end of the second connection part 102, the bottom end of the first connection part 101 is provided with a first placement groove 201, and the top end of the second connection part 102 is provided with a second placement part connected to the first placement groove 201 The first placement groove 201 cooperates with the second placement groove 202 for placing the sealing gasket 3, so as to form a seal at the connection between the first connection part 101 and the second connection part 102. A sealing gasket 3 is arranged between the first placement groove 201 and the second placement groove 202, and a receiving groove 301 is arranged inside the sealing gasket 3. A plurality of pressure-resistant bodies 4 are arranged inside the receiving groove 301 at intervals. The pressure-resistant bodies 4 are composed of two arc-shaped bodies arranged in a mirror image. The plurality of pressure-resistant bodies 4 facilitate evenly aligning the top and bottom ends of the sealing gasket 3 with the first placement groove 201 and the second placement groove 202. The two arc-shaped bodies are arranged in an upper and lower mirror image, and the open end of the top of the pressure-resistant body 4 conflicts with the top of the inside of the accommodating groove 301, and the open end of the bottom of the pressure-resistant body 4 conflicts with the bottom of the inside of the accommodating groove 301. The pressure-resistant body 4 applies a pressing force to the sealing gasket 3, driving the top of the sealing gasket 3 to conflict with the top of the inside of the first placement groove 201, and the bottom of the sealing gasket 3 conflicts with the bottom of the inside of the second placement groove 202. After the first connecting part 101 and the second connecting part 102 are matched, the inner walls of the first placement groove 201 and the second placement groove 202 are in close contact with each other. The sealing gasket 3 generates a clamping force, which then squeezes the pressure-resistant body 4 in the accommodating groove 301, causing the pressure-resistant body 4 to undergo elastic deformation. The pressure-resistant body 4 generates a reverse force in the accommodating groove 301, which tightly fits the top and bottom ends of the sealing gasket 3 with the inner walls of the first placement groove 201 and the second placement groove 202, so that no gap is generated between the top and bottom ends of the sealing gasket 3 and the first placement groove 201 and the second placement groove 202, and the pressure-resistant body 4 always applies a directional force to make it fit firmly, thereby improving its sealing performance, preventing oil and air leakage, and making the engine work more stably.
[0019] A first protrusion 501 is formed downward at the center of the top end of the first placement groove 201, and a second protrusion 502 is formed upward at the center of the bottom end of the second placement groove 202. A first connecting groove 302 matching the first protrusion 501 is opened at the top of the sealing gasket 3, and a second connecting groove 303 matching the second protrusion 502 is opened at the bottom of the sealing gasket 3. The first protrusion 501 and the second protrusion 502 cooperate with the first connecting groove 302 and the second connecting groove 303 to form multiple seals from the cover body 1 and the inner side of the engine cylinder block to the outer side of the first connecting part 101 and the second connecting part 102, and form a maze-shaped structure, which further increases its sealing performance, prevents oil leakage and air leakage, and makes the engine work more stably.
[0020] A vertically arranged support portion 6 is provided in the middle of the accommodating groove 301 , and the pressure-resistant body 4 is located on both sides of the support portion 6 . The support portion 6 and the sealing gasket 3 are integrally formed with the same material to increase the structural stability of the sealing gasket at the accommodating groove 301 .
