[0063] In the embodiment of the utility model, a receiving cavity 11 corresponding to the flange 10 is formed on the inner side of the second sealing portion 5, and the flange 10 abuts against the receiving cavity 11, so that the second sealing portion 5 forms a first sealing end 12 for abutting against the outer wall of the inner groove 7, a second sealing end 13 abutting against the inner wall of the inner groove 7 and a third sealing end 14 abutting against the inner bottom of the inner groove 7.

[0064] The second sealing portion 5 is divided and formed into a first sealing end 12 for abutting against the outer wall of the inner groove 7, a second sealing end 13 for abutting against the inner wall of the inner groove 7, and a third sealing end 14 for abutting against the inner bottom of the inner groove 7, so that the second sealing portion 5 can effectively strengthen the tight fit of the second sealing portion 5 in the inner groove 7 under the abutment action of the flange 10, thereby effectively ensuring the sealing performance of the seal 3.

[0065] In the embodiment of the utility model, the cross section of the sealing member 3 is in a Z shape.

[0066] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
