Furthermore, a folding groove is arranged below the locking block at the joint of the locking part and the sealing part.
Furthermore, a dovetail groove is arranged at the position of the socket structure corresponding to the locking block and the groove, and the dovetail groove, the locking block and the groove form an interlocking dovetail locking structure.
Further, each sealing ring is triangular in cross section.
Further, the number of the seal rings is 2.
Further, the number of the locking blocks is 2.
Furthermore, a step for preventing the excessive stretching of the seal is arranged on the bellmouth structure; correspondingly, one end angle of the sealing part of the sealing structure, which is far away from the locking block, is set to be a chamfer matched with the step.
Compared with the prior art, the invention has the following technical effects:
according to the invention, the step for preventing the excessive stretching of the seal is arranged on the socket structure, so that the seal structure can be protected from being damaged due to the excessive stretching of the seal structure when another pipe socket is inserted in the construction process; and take off from the mould after the body production is accomplished, fold seal structure outside to the body in, the sealing ring on the seal structure this moment is inside towards the body, seal structure is whole inside the body, in the transport, can not be damaged in the storage process, the socket surface of another body contacts with seal structure earlier during the construction, and the extrusion, form the sealed system of no seepage, in the bellmouth structure in-process of inserting another body, seal structure can be promoted to intraductal removal, when moving on the bellmouth step on the seal ring, seal structure is obstructed no longer along with the bayonet removal, thereby protection seal structure is broken. The device of the invention has the advantages of simple and convenient construction, short time, low cost, firm structure and difficult damage.
