[0007] Furthermore, the positioning mechanism includes a positioning ring, a limiting groove and a locking rod, and there are two positioning rings. The two positioning rings are symmetrically arranged with the mid-vertical line of the corrugated pipe body as the symmetry axis. A limiting groove is opened on the outer side of one positioning ring, and a locking rod is fixedly installed on the outer side of the other positioning ring in a ring-shaped manner at equal distances.

[0008] Furthermore, the outer dimensions of the locking rod are completely consistent with the inner dimensions of the limiting groove, and the locking rod forms a snap-fit ​​structure with the positioning ring through the limiting groove.

[0009] Furthermore, the locking assembly includes an arc-shaped locking plate, a first connecting block, a first fastening bolt, a second connecting block and a second fastening bolt, and the first connecting blocks are symmetrically fixedly connected to both sides of the arc-shaped locking plate, and the internal threads of the first connecting block are connected to the first fastening bolt, and the top of the arc-shaped locking plate is fixedly installed with the second connecting block, and the internal threads of the second connecting block are connected to the second fastening bolt.

[0010] Furthermore, there are two arc-shaped locking plates, and the two arc-shaped locking plates are symmetrically arranged with the mid-perpendicular line of the connecting end as the symmetry axis, and the inner surface of the arc-shaped locking plate is fit-connected to the outer surface of the connecting end, and the inner side of the arc-shaped locking plate is fit-connected to the inner side of the positioning mechanism.

[0011] Furthermore, the protective assembly includes an arc-shaped sealing cover, a fixing block, a fixing bolt and an arc-shaped sealing rubber pad, and the fixing blocks are symmetrically fixedly connected on both sides of the arc-shaped sealing cover, and the internal threads of the fixing blocks are connected to the fixing bolts, and the inner surface of the arc-shaped sealing cover is symmetrically installed with an arc-shaped sealing rubber pad.

[0013] The utility model provides a bellows with an anti-leakage structure, which has the following beneficial effects:

[0014] 1. The utility model provides a limit groove and a locking rod, so that the two positioning rings are convenient for workers to quickly connect and install, thereby quickly completing the initial connection and installation work of the connection end, and the first connecting block and the first fastening bolt are provided, so that the upper and lower arc-shaped locking plates can be quickly installed on the end outer surface of the connection end, and then the second connecting block and the second fastening bolt are provided, so that the front and rear sets of arc-shaped locking plates can be gradually brought together to complete the quick locking work, thereby ensuring that the connection of the connection end will not be loose, so that the bellows is convenient for workers to quickly disassemble and assemble, thereby providing convenience for workers to inspect and replace the bellows.

[0015] 2. The utility model provides a fixing block and a fixing bolt, so that the protective component is easy for the staff to quickly install on the outer surface of the locking component. At this time, the arc-shaped sealing cover and the arc-shaped sealing rubber pad cooperate with each other to complete the sealing and wrapping protection of the connection end, thereby avoiding the loosening of the connection of the bellows during long-term use, causing the conveying medium to leak out of the connection. At the same time, the cooperation between the positioning mechanism and the locking component can greatly reduce the probability of loosening of the connection, thereby further improving the anti-leakage effect of the bellows.
