And the rubber rings 130 can be sleeved on both ends of the fixing rod 720 by "the fixing rod 720 is formed with an external thread at the center in the length direction and connected with two nuts 721", and once the positions of the plurality of fixing rods 720 relative to the base plate 710 are determined, the rubber rings 130 on both ends of the fixing rod 720 keep the same shape, so that one rubber ring 130 can be sleeved on both ends of the fixing rod 720; after one rubber ring 130 is mounted in the sealing groove 121, the base plate 710 is turned over, and then the other rubber ring 130 is fitted in the sealing groove 121 of the other housing 120. Thereby doubling the efficiency of rubber ring 130 installation.

Referring to fig. 4 to 10, preferably, bosses 722 are formed at both end portions of the fixing rod 720, respectively, a cavity 122 is formed at one side surface of the case 120, the sealing groove 121 is opened around the cavity 122, the case 120 between the sealing groove 121 and the cavity 122 is in contact with the bottom surface of the boss 722, and the side surface of the boss 722 is in contact with the side wall of the cavity 122.

Because the rubber ring 130 has elasticity, in the process of transferring the rubber ring 130 to the sealing groove 121 from the fixing rod 720 after the rubber ring 130 is sleeved on the fixing rod 720, if there is a deviation in the positioning of the fixing rod 720 and the sealing groove 121, the rubber ring 130 is deformed and cannot be sleeved in the sealing groove 121 in the process of separating from the fixing rod 720.

Therefore, the inventor of the present invention has observed that "the cavity 122 is formed on one side surface of the casing 120, the sealing groove 121 is opened around the cavity 122, and there is a top surface gap between the sealing groove 121 and the cavity 122", it is just possible to bring the casing 120 between the sealing groove 121 and the cavity 122 into contact with the bottom surface of the boss 722, and bring the side surface of the boss 722 into contact with the side wall of the cavity 122, so that the positioning of the fixing rod 720 and the casing 120 is realized by using the edge of the boss 722 placed in the cavity 122. Thereby ensuring that the rubber ring 130 can smoothly enter the sealing groove 121.

Referring to fig. 4 to 10, preferably, the fixing rod 720 is a cylinder, the cross section of the boss 722 is a semicircle, and the center of the boss 722 is coaxial with the center of the fixing rod 720.

Considering that the gap to be reserved on the side surface of the boss 722 is different at different edges of the cavity 122, that is, the gap "between the sealing groove 121 and the cavity 122 and the top surface gap" exists differently, in order to adjust the "contact area between the casing 120 and the boss 722 between the sealing groove 121 and the cavity 122" according to the gap, the "cross section of the boss 722 is skillfully semicircular, the center of the boss 722 is coaxially arranged with the center of the fixing rod 720", and according to the size of the "contact area between the casing 120 and the boss 722 between the sealing groove 121 and the cavity 122", the boss 722 can be rotated to different positions, so that the "contact area between the casing 120 and the boss 722 between the sealing groove 121 and the cavity 122" is changed to meet the size of the gap "between the sealing groove 121 and the cavity 122 and the top surface gap".

Referring to fig. 4 to 10, preferably, the rubber ring 130 mounting tooling mechanism further includes an auxiliary plate 740, the auxiliary plate 740 is an elongated plate, two ends of the same side plate surface of the auxiliary plate 740 form protrusions 741 at the same time, the auxiliary plate 740 covers the side plate surface of the pressing plate 730, the side of the pressing plate 730 is disposed between the two protrusions 741, and the side of the pressing plate 730 is communicated with one end of the first elongated through hole 711.

Since the side edge of the pressing plate 730 is communicated with one end of the first elongated through hole 711, when an assembler presses the rubber ring 130 into the sealing groove 121 through the pressing plate 730, the side edge of the pressing plate 730 is inconvenient for the assembler to operate, and the height of the rubber ring 130 pressed into the sealing groove 121 is deviated, for this reason, the inventor of the present invention prevents the auxiliary plate 740 from moving relative to the pressing plate 730 by placing the auxiliary plate 740 on one side of the pressing plate 730 and placing the auxiliary plate 740 between the two protrusions 741 through the side edge of the pressing plate 730, so that the assembler can press both sides of the pressing plate 730 simultaneously. The assembling efficiency of the rubber ring 130 is ensured.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
