Referring to fig. 1-3, the present invention provides a technical solution:

a kind of polytetrafluoroethylene soft rubber pad, including the rubber gasket 2 set up in the outer end of 3 opening of pipeline; the utility model discloses a pipeline 3 opening part edge is equipped with spacing groove 32, the spacing groove 32 outside is equipped with a plurality of screw holes 31, the equal fixedly connected with spacing lug 22 in both ends about the rubber packing ring 2, the inboard fixedly connected with slope ring 23 of

rubber packing ring

2, 2 opposite sides of rubber packing ring are equipped with

sealing cover

1, 1 edges of sealing cover are equipped with a plurality of trompils 11, all be equipped with a bolt 4 in the

trompil

11, 1 inboard of sealing cover is equipped with covers groove 12.

In this embodiment, the opening 11, the limiting hole 21 and the threaded hole 31 correspond to each other one by one, and the bolt 4 passes through the opening 11 and the limiting hole 21 and is in threaded connection with the threaded hole 31, so that the sealing cover 1, the rubber gasket 2 and the pipeline 3 are fixedly connected together, and the rubber gasket 2 is fixed at the position of the sealing cover 1 by the bolt so as not to rotate and twist.

In this embodiment, the limiting protrusions 22 are respectively inserted into the cover grooves 12 and the limiting grooves 32, so that the limiting protrusions 22 can function as fixing positions and can prevent external dust from entering the inside of the rubber gasket 2.

In this embodiment, the inclined surface of the inclined ring 23 faces the inner side of the pipe 3, and the straight surface faces the sealing cap 1, so that when pressure is generated inside the pipe 3, part of the pressure can be decomposed into thrust force towards the sealing cap 1, and the sealing cap 1 is fixed at the opening of the pipe 3 by the bolt 4 and is abutted against the opening, thereby reducing the stress degree of the rubber gasket 2 and reducing the occurrence of cracks on the rubber gasket 2.

In this embodiment, the height of the limiting protrusion 22 is equal to the depth of the cover groove 12 and the limiting groove 32, so that the top end of the limiting protrusion 22 is tightly attached to the bottom ends of the cover groove 12 and the limiting groove 32, thereby sealing the inside.

In this embodiment, the straight surface of the inclined ring 23 is tightly attached to the surface of the sealing cap 1, and the outer side of the rubber gasket 2 is tightly attached to the sealing cap 1, so that the sealing cap 1 can provide a better supporting force.

When the polytetrafluoroethylene soft rubber gasket of the embodiment is used, a user firstly inserts the limiting lug 22 of the rubber gasket 2 into the cover groove 12 of the sealing cover 1, so that the straight surface of the inclined ring 23 on the rubber gasket 2 is tightly attached to the inner surface of the sealing cover 1, then inserts the limiting lug 22 on the other side of the rubber gasket 2 into the limiting groove 32 on the pipeline 3, the open hole 11, the limiting hole 21 and the threaded hole 31 are in one-to-one correspondence, the bolt 4 penetrates through the open hole 11 and the limiting hole 21 and is inserted into the threaded hole 31 to be in threaded connection with the threaded hole, so that the rubber gasket 2 is fixed between the sealing cover 1 and the pipeline 3, when the gasket is used, when gas or liquid and the like in the pipeline generate pressure, the inclined ring 23 arranged inside the rubber gasket 2 can partially decompose pressure in the sealing cover 1, so as to reduce the transverse pressure on the rubber gasket 2, thereby reducing the condition that crack damage is easily caused to the rubber gasket 2, and the limiting lug 22 can effectively prevent dust from entering the rubber gasket 2, thereby accurately fixing the position of the rubber gasket 2 and ensuring the sealing performance in the pipeline 3.

Can realize the sealed work of rubber pad through above-mentioned mode to avoided the rubber pad to use the problem that the appearance damaged and leakproofness reduces for a long time.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only the preferred embodiments of the present invention, and is not intended to limit the present invention, and that there may be various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall within the scope of the present invention as claimed.
