[0021] When the present invention is performing docking work on the connecting pipe 1 and the flange rubber tube 2, that is, when the docking flange bodies 3 at the ends of the two are aligned and the mounting hole grooves 31 in the docking flange bodies 3 of the two are aligned, in order to ensure that the docked docking flange bodies 3 will not loosen or be misaligned during the installation process, the docking positioning cylinders 402 are inserted one by one into the mounting hole grooves 31 in the aligned docking flange bodies 3. The docking positioning cylinders 402 set at this time can provide a limiting support for the mounting hole grooves 31 that have been aligned, thereby avoiding the problem of loosening and misalignment of the docked docking flange bodies 3 during the connection and fixing work; one end of the docking positioning cylinder 402 in the docking auxiliary component is fixedly provided with a limiting ring body 401, and the outer side wall of the docking positioning cylinder 402 is sleeved with a rubber sleeve 403, and the docking positioning cylinder 402 is adapted to be plugged in with the mounting hole groove 31; the end face of the limiting ring body 401 is provided with a fastening card groove 404, and the fastening card grooves 404 are equidistantly arranged in a ring shape.

[0022] For the plug-in connection between the docking positioning cylinder 402 and the mounting hole groove 31, the first docking positioning cylinder 402 is inserted into one of the mounting hole grooves 31 of the docking flange body 3, and the limiting ring body 401 at one end of the docking positioning cylinder 402 is tightly attached to the docking flange body 3, and then the docking positioning cylinder 402 is inserted into the mounting hole groove 31 at other positions of the docking flange body 3. A docking positioning cylinder 402 is plugged into one mounting hole groove 31.

[0023] Example 2: Based on Example 1, please refer to Figure 5-Figure 12 In the actual installation and connection work, the use of the docking positioning cylinder 402 is mainly to prevent the aligned docking flange body 3 from loosening and dislocation.

[0024] When the docking positioning cylinder 402 needs to be disassembled, it can be used in a turnover manner. This solution uses a first anti-loosening component to perform a fastening connection, wherein one end of the connecting threaded cylinder 501 in the first anti-loosening component is fixedly provided with a cylindrical screw head 502, and the connecting threaded cylinder 501 is threadedly connected to the hexagonal nut 503; one end of the cylindrical screw head 502 is embedded and fixedly provided with a rubber pad 504, and the center position of the end face of the rubber pad 504 is provided with a docking slot 505, that is, in the process of using the connecting threaded cylinder 501 to connect and fix the docking flange body 3 of the connecting pipe 1 and the flange rubber tube 2, during the plug-in work of the first connecting threaded cylinder 501, any one of the docking positioning cylinders 402 that has been inserted into the mounting hole groove 31 can be taken out first, and then the connecting threaded cylinder 501 can be inserted into the mounting hole groove 31.

When using the connection threaded cylinder 501 and the hexagonal nut 503 to connect and fix, the docking positioning cylinder 402 inserted into the mounting hole groove 31 can avoid the problem of misalignment of the aligned docking flange body 3 during connection and fixation, thereby improving the convenience of its installation work; then the docking positioning cylinders 402 in the mounting hole grooves 31 at other positions are taken out one by one, and then the connection threaded cylinder 501 and the hexagonal nut 503 are used to connect and fix.

[0025] In order to further improve the connection stability between the connecting threaded column 501 and the connecting pipe 1 and the flange rubber tube 2, that is, to avoid the problem of loosening in subsequent work, this solution is achieved by setting up an anti-loosening support component, wherein one end of the support screw 601 in the anti-loosening support component is fixedly provided with a fixed disk 602, and the other end of the fixed disk 602 is fixedly provided with a first support head 603, and the first support head 603 is threadedly connected to the internal thread support cylinder 604; one end of the internal thread support cylinder 604 is sealed, and the end of the sealing setting is fixedly provided with a second support head 605, and the side wall of the internal thread support cylinder 604 at the end threadedly connected to the support screw 601 is fixedly provided with a rotation auxiliary ridge 606, and the second support head 605 and the first support head 603 are both They are all compatible and plugged into the docking slots 505; that is, after each group of connecting threaded columns 501 are installed, the first supporting head 603 at one end of the supporting screw rod 601 is inserted into the docking slot 505 at the end of the cylindrical screw head 502 provided on the docking flange body 3 at one end of the flange rubber tube 2, and then the internal threaded support tube 604 is rotated until the second supporting head 605 at one end of the internal threaded support tube 604 is inserted into the docking slot 505 at the end of the cylindrical screw head 502 provided on the docking flange body 3 at the other end of the flange rubber tube 2, and finally the internal threaded support tube 604 is tightened, wherein the internal threaded support tube 604 and the supporting screw rod 601 are used together as a supporting regulating rod, which squeezes the installed cylindrical screw head 502, thereby providing an squeezing locking effect.

[0026] Example 3: Based on Example 2, please refer to Figure 13-16After the first end of the pipe 1 is connected to the flange 31, the second end of the pipe 1 is connected to the flange 31, and the flange 31 is connected to the flange 32. When the cap 702 is screwed in place, the locking nut 703 is unlocked and the locking nut 704 is unlocked, and the locking nut 703 is unlocked.

[0027] In order to further improve the stability of its connection, this scheme is further stabilized by setting up a clamping structure, wherein the clamping structure includes a through slot 801, a plug-in strip 802, a clamping head 803 and an auxiliary pull buckle 804; the through slot 801 is set in the fastening cap body 702, and the notch at one end of the through slot 801 is connected to the accommodating cavity 704, the plug-in strip 802 is adapted to be plugged in with the through slot 801, and one end of the plug-in strip 802 is fixedly provided with an auxiliary pull buckle 804, and the end of the plug-in strip 802 is provided with a clamping head 803, and the clamping head 803 is adapted to be clamped in with the fastening card slot 404 on the limiting ring body 401, that is, after the fastening cap body 702 is screwed in, the through slot 801 set in the fastening cap body 702 is adapted to be clamped in with the fastening card slot 404 set on the limiting ring body 401 The slots 404 are set at corresponding positions, and the fastening slots 404 are equidistantly arranged in a ring shape on the limiting ring body 401. The auxiliary pull buckle 804 is held by hand to insert the plug-in strip 802 into the through slot 801 until the clamping head 803 at one end of the plug-in strip 802 is clamped with the fastening slot 404 at the corresponding position. In this process, when the second anti-loosening component is used to prevent loosening and stabilize, the docking positioning cylinder 402 is not removed. On the one hand, the construction steps can be reduced and the connection work efficiency can be improved. On the other hand, the fastening slots 404 set on the limiting ring body 401 at the end of the docking positioning cylinder 402 can be used in conjunction with the plug-in strip 802, thereby providing a stabilizing effect for the threaded connection between the fastening cap body 702 and the connecting pin 701, thereby having better anti-loosening properties.
