[0029] Reference Figure 1-6 As shown, the fixing device 3 includes two symmetrical grooves 31, and the two grooves 31 are opened on the arc surface of the rubber ring 2. The flange body 1 is provided with a mounting groove 34 corresponding to the rubber ring 2, and the size of the mounting groove 34 is adapted to the size of the rubber ring 2. The rubber ring 2 is fixedly connected with a spring 32 by means of the groove 31, and one end of the spring 32 is fixedly connected with a clamping block 33. The flange body 1 is provided with a clamping groove 35 corresponding to the clamping block 33, and the size of the clamping groove 35 is adapted to the size of the clamping block 33. The end of the clamping block 33 away from the rubber ring 2 is fixedly connected with a triangular plate 36. When the staff needs to replace the aged rubber ring 2, the staff moves the rubber ring 2 and inserts the rubber ring 2 into the mounting groove 34 of the flange body 1. At this time, the inner wall of the mounting groove 34 of the flange body 1 squeezes the inclined surface of the triangular plate 36, and the triangular plate 36 moves toward the inner direction of the groove 31 with the clamping block 33, and the spring 32 contracts. When the rubber ring 2 moves to the position of the clamping groove 35 with the clamping block 33, under the action of the restoring elastic force of the spring 32, the clamping block 33 inserts the triangular plate 36 into the clamping groove 35, thereby achieving the effect of fixing the rubber ring 2. The fixing device 3 achieves the effect of fixing the rubber ring 2 and the flange body 1. When the rubber ring 2 ages, it is convenient for the staff to replace the rubber ring 2.

[0030] Reference Figure 1-6 As shown, the inner wall of the groove 31 is fixedly connected with a telescopic rod 37, and one end of the telescopic rod 37 is fixedly connected with the block 33. By setting the telescopic rod 37, the moving direction of the block 33 is limited, the block 33 is prevented from rotating, and the stability of the movement of the block 33 is improved. A plurality of control grooves 39 are evenly provided inside the rubber ring 2, and the plurality of control grooves 39 are distributed in a circumference. The staff inserts the finger into the control groove 39 of the rubber ring 2, which makes it convenient for the staff to move the rubber ring 2, bringing convenience to the staff. A plurality of concentric rubber rings 38 are fixedly connected to the upper surface of the rubber ring 2. When the two flange bodies 1 are close to each other, the rubber ring 38 on one of the rubber rings 2 squeezes the rubber ring 38 on the other rubber ring 2, and the rubber rings 38 on the two rubber rings 2 are deformed and fit together to form a plurality of annular sealing areas, thereby improving the sealing effect of the rubber ring 2.

[0031] Reference Figure 1-6As shown, the auxiliary device 4 includes a fixing ring 41, which is fixedly connected to the side of the rubber ring 2 close to the flange body 1, and a plurality of positioning rods 42 are fixedly connected to the side of the fixing ring 41 away from the rubber ring 2. The plurality of positioning rods 42 are distributed in a circumference, and a positioning groove 43 is provided at the flange body 1 corresponding to the positioning rod 42, and the size of the positioning groove 43 is slightly larger than the size of the positioning rod 42. When installing the rubber ring 2, the positioning rod 42 on the rubber ring 2 is inserted into the positioning groove 43 of the flange body 1, so as to achieve the effect of limiting the rubber ring 2. The auxiliary device 4 achieves the effect of limiting the rubber ring 2, and prevents the rubber ring 2 from shaking in the installation groove 34 of the flange body 1 due to its own elasticity, thereby improving the stability of the rubber ring 2.

[0032] Reference Figure 1-6 As shown, one end of the positioning rod 42 away from the fixing ring 41 is fixedly connected with a pointed protrusion 44, and the tip of the pointed protrusion 44 is away from the positioning rod 42. The provision of the pointed protrusion 44 facilitates the staff to insert the positioning rod 42 into the positioning groove 43, which brings convenience to the staff. The arc surface of the positioning rod 42 is fixedly connected with a plurality of rubber blocks 45, and the rubber blocks 45 are inclined toward the direction of the fixing ring 41. When the positioning rod 42 enters the positioning groove 43 with the rubber blocks 45, the inner wall of the positioning groove 43 squeezes the rubber blocks 45, and the rubber blocks 45 are deformed. When the positioning rod 42 moves out of the positioning groove 43, the rubber blocks 45 clamp the positioning rod 42, and the positioning rod 42 is prevented from moving out of the positioning groove 43 as much as possible, thereby improving the fixing effect of the rubber ring 2.

[0033] Working principle: When the staff needs to replace the aged rubber ring 2, the staff moves the rubber ring 2 through the control groove 39, and the rubber ring 2 is inserted into the mounting groove 34 of the flange body 1.

When the rubber ring 2 moves to the position of the card slot 35 with the card block 33, under the action of the spring 32 reset elastic force, the card block 33 inserts the triangular plate 36 into the card slot 35, thereby achieving the effect of fixing the rubber ring 2. When the two flange bodies 1 are connected, when the two flange bodies 1 are close to each other, the rubber ring 38 on one of the rubber rings 2 squeezes the rubber ring 38 on the other rubber ring 2, and the rubber rings 38 on the two rubber rings 2 are deformed and fit together to form a number of annular sealing areas, thereby improving the sealing effect of the rubber ring 2. The fixing device 3 achieves the effect of fixing the rubber ring 2 and the flange body 1. When the rubber ring 2 is aged, it is convenient for the staff to replace the rubber ring 2.
