For further explaining the present embodiment, referring to fig. 4, the seal reinforcing part 400 includes a first sealing lip 402, a bending rod 403, a second sealing lip 404, a first shaft 405, a first connecting rod 406, a second connecting rod 407, and a first spring 408, the inner surface of the door 200 is coaxially fixed to one end surface of the fixed cylinder 401, the other end surface of the fixed cylinder 401 abuts against one end of the bending rod 403, the first sealing lip 402 is fixed to the outer circumferential surface of the fixed cylinder 401, the first sealing lip 402 is arc-shaped, the inner arc surface of the first sealing lip is fixed to the outer circumferential surface of the fixed cylinder 401, the middle part of the bending rod 403 is fixed to the first shaft 405, the first shaft 405 is mounted on the first connecting rod 406 through a bearing, the first connecting rod 406 is fixed to one end of the first spring 408, the other end of the first spring 408 is fixed to one end of the bending rod 403 close to the fixed cylinder 401, the first connecting rod 406 is fixed to the second connecting rod 407, the second connecting rod 407 is fixed to the inner surface of the housing 100, the other end of the bent rod 403 faces the first sealing lip 402 and is fixed to the second sealing lip 404, the inner arc surface of the second sealing lip 404 can overlap with the outer arc surface of the first sealing lip 402, and the outer arc surface of the second sealing lip 404 overlaps with the inner surface of the housing 100.

According to the invention, when the fixed cylinder 401 is screwed along the screw thread of the door hole 101 of the shell 100 along with the door 200, the fixed cylinder 401 continuously abuts against one end of the bending rod 403 to realize that the other end of the bending rod 403 can swing towards the outer end surface of the fixed cylinder 401, so that the first sealing lip 402 abuts against the second sealing lip 404, the self-locking capability of the screw thread of the door 200 and the door hole 101 is enhanced through the counterforce of the abutting of the first sealing lip 402 and the second sealing lip 404 and the elastic resetting capability, the sealing performance of the screw thread is enhanced, and the enhanced sealing is realized through the first sealing lip 402 and the second sealing lip 404.

The second sealing lip 404 is a ring with an arc-shaped cross section and is used for sealing the door 200 and the housing 100, so that one end of the second sealing lip is sealed with the first sealing lip 402 of the fixed cylinder 401 of the door 200, and the other end of the second sealing lip is overlapped with the inner surface of the housing 100 to realize sealing. The plurality of second sealing lips 404 may form an annular shape having an arc-shaped cross section. The plurality of second seal lips 404 overlap each other to achieve a seal.

The first sealing lip 402 is detachably and fixedly connected with the outer circumferential surface of the fixed cylinder 401, for example, the first sealing lip 402 is connected with the outer circumferential surface of the fixed cylinder 401 through a screw, a glue, a double-sided tape, or a magic tape, so that when the glove 300 needs to be completely replaced, the first sealing lip 402 is firstly removed and then the door 200 is screwed out.

After the door 200 is screwed out of the door hole 101, the first sealing lip 402 can be taken out after being bent by directly utilizing the flexibility of the first sealing lip 402, or the outer diameter of the circumference formed by the outer arc surface of the first sealing lip 402 should be smaller than the inner diameter of the door hole 101, so that the first sealing lip 402 and the fixed cylinder 401 can be screwed out smoothly.

Wherein the first link 406 is arranged perpendicular to the second link 407.

To further explain the present embodiment, referring to fig. 4, 5 and 6, the at least three sets of first sealing lips 402 are disposed along the longitudinal direction of the fixed cylinder 401, and the at least three sets of second sealing lips 404 are disposed along the longitudinal direction of the other end portion of the bent rod 403.

The present invention further enhances the sealing by providing at least three sets of first and

second lips

402, 404 that cooperate with each other as described above.

The first sealing lip 402 and the second sealing lip 404 may be configured as 3, 4, 5, 6, 7, 8, 9, 10 sets, which are matched with each other.

For further explanation of the present embodiment, referring to fig. 4, 5 and 6, the outer diameters of the at least three sets of first sealing lips 402 gradually decrease from the position near the door 200 to the position far from the door 200, and the outer diameters of the at least three sets of first sealing lips 402 gradually increase from the position near the door 200 to the position far from the door 200.

According to the invention, the at least three groups of first sealing lips 402 and the at least three groups of second sealing lips 404 arranged in the ladder-type manner can be used for dispersing the pressure and the friction force generated when the first sealing lips 402 and the second sealing lips 404 are combined to each group of first sealing lips 402 and second sealing lips 404 when the other end part of the bending rod 403 swings, so that the phenomenon that the pressure and the friction force are uneven to realize local failure and cause sealing failure is avoided.

For further explanation of the present embodiment, referring to fig. 4, 5 and 6, the intrados of the second lip 404 tapers from away from the first lip 402 to proximate the first lip 402.

According to the invention, the second sealing lip 404 which is gradually thinned, namely the second sealing lip 404 with a relatively sharp end can better extend into the gap between the first sealing lips 402, so that the influence on the swinging of the bending rod 403 is avoided.

For further explanation of the present embodiment, referring to fig. 4, the inner circumferential surface of the end of the fixed cylinder 401 away from the door 200 is fixed to the outer circumferential surface of the reinforcing ring 420.

The present invention can increase the allowable swing range of the bending rod 403 by the reinforcing ring 420, so as to avoid that when the thickness of the fixing cylinder 401 is small, the bending rod 403 with large swing range cannot be handled, so that the bending rod 403 cannot be pushed against one end of the bending rod 403, and one end of the bending rod 403 cannot slide on the end of the fixing cylinder 401.

The thickness of the fixed cylinder 401 should be larger, that is, the fixed cylinder 401 is abutted against the end surface of the fixed cylinder 401 after the end of the fixed cylinder 401 and the bending rod 403 are initially abutted against the end surface of the bending rod 403 and bent, and after the fixed cylinder 401 moves a certain distance above the end surface of the fixed cylinder 401, the end surface of the fixed cylinder 401 is still abutted against the end surface of the fixed cylinder 401 and is not separated from the end surface of the fixed cylinder 401 during the bending process of the bending rod 403. If necessary, a reinforcing ring 420 may be fixed to an end surface of the fixed cylinder 401, and when the thickness of the fixed cylinder 401 is constant, the reinforcing ring 420 overlaps the bending bar 403, thereby further preventing a failure in the connection between one end of the bending bar 403 and the fixed cylinder 401.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
