DETAILED DESCRIPTION

[0019] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-2 As shown, an oil-resistant shock-absorbing sealing gasket for automobiles comprises a lower gasket 1 and an upper gasket 2; the upper gasket 2 is provided with a plug-in port 12; the top of the lower gasket 1 is fixedly connected with an outer ring plate 6 and an inner ring plate 7, the outer ring plate 6 surrounds the inner ring plate 7 and forms an annular gap; the top of the inner ring plate 7 is fixedly connected with a first ring plate 3 and a second ring plate 4; the bottom of the upper gasket 2 is fixedly connected with a plug-in plate 5, which is adapted to be plugged into the gap between the first ring plate 3 and the second ring plate 4.

[0021] An inner beveled ring 31 is fixedly connected to the inner side surface of the first ring plate 3, and an outer beveled ring 51 is fixedly connected to the outer side surface of the plug-in board 5. The inclined surfaces of the inner beveled ring 31 and the outer beveled ring 51 are in contact with each other and are elastic; the inner beveled ring 31 is integrally formed with the first ring plate 3, and the outer beveled ring 51 is integrally formed with the plug-in board 5.

[0022] A threaded slot is provided between the opposite surfaces of the outer ring plate 6 and the inner ring plate 7; a spring 9 is also fixedly connected to the bottom of the upper gasket 2, and a threaded opening 8 is fixedly connected to the bottom of the spring 9, and the threaded opening 8 is adapted to be threadedly connected to the threaded slot.

[0023] The upper gasket 2 is provided with an insertion port 12 , and the upper gasket 2 is provided with guide grooves 10 evenly arranged around the insertion port 12 . A hoop 11 for reducing oil leakage is fixedly connected to the inner wall of the insertion port 12 .

[0024] An oil groove 14 is provided on the top of the lower gasket 1 to collect leaked oil and prevent it from being polluted.

[0025] The upper gasket 2 and the lower gasket 1 are both made of oil-resistant rubber materials, the outer ring plate 6 and the inner ring plate 7 are made of hard metal materials, and a fixing rod 13 for maintaining the relative distance between the outer ring plate 6 and the inner ring plate 7 is fixedly connected inside the lower gasket 1.

[0026] Working principle: When in use, the sealing gasket is mainly composed of a lower gasket 1 and an upper gasket 2. Both the lower gasket 1 and the upper gasket 2 are made of oil-resistant rubber material, which can maintain stable performance in an environment of long-term contact with oil and prevent the oil from corroding the gasket;

[0027] Insert the plug-in board 5 into the gap between the first ring plate 3 and the second ring plate 4, and the outer bevel ring 51 and the inner bevel ring 31 fit each other. Since the bevel surfaces of both have a certain elasticity, they can deform and slide relative to each other when compressed, thereby forming a stable clamping connection;

[0028] When the plug-in board 5 is clamped between the first ring plate 3 and the second ring plate 4, the threaded opening 8 just enters the threaded slot between the outer ring plate 6 and the inner ring plate 7, and the upper gasket 2 is rotated so that the threaded opening 8 is threadedly connected between the outer ring plate 6 and the inner ring plate 7, and the fixing rod 13 maintains the relative stability between the outer ring plate 6 and the inner ring plate 7, thereby ensuring the connection stability between the upper gasket 2 and the lower gasket 1;

[0029] During the working process of the gasket, when the pressure is too large, the spring 9 will buffer part of the pressure, and the oil will flow from the guide groove 10 to the plug-in port 12, avoiding the oil from overflowing from the top of the upper gasket 2 and causing pollution. The hoop 11 blocks the oil overflowing downward, and part of the oil flows from the plug-in port 12 into the oil groove 14 at the top of the lower gasket 1, again avoiding the oil from overflowing from the bottom of the plug-in port 12 and causing pollution;

[0030] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
