Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides a connecting pipeline of a municipal drainage system.

In this embodiment, referring to fig. 1-2, the connecting pipe of the municipal drainage system includes a first pipe 1 and a second pipe 2, an internal thread 3 is provided on the inner wall of the flow channel of the first pipe, a positioning ring 4 is extended from the end of the first pipe, a connecting pipe 5 is extended from the end of the second pipe, an external thread 6 connected to the internal thread is provided on the outer wall of the connecting pipe, and a ring groove 7 for inserting the positioning ring is provided on the second pipe.

Among the above-mentioned technical scheme, through setting up holding ring and annular, when pipe and pipe threaded connection, insert the annular through the holding ring and carry out prepositioning in, improve the centering effect of being connected between pipe and the pipe, effectively avoid appearing the dead problem of card because threaded connection is not aligned, improve dismouting efficiency.

Specifically, the upper side and the lower side of the top of the positioning ring are provided with pouring slopes to enable the top of the positioning ring to form a pouring tip 8.

By arranging the pouring tip, the positioning ring can be conveniently inserted into the annular groove.

Specifically, the device also comprises a stabilizing sleeve 9, wherein a sliding groove 10 is formed in the inner wall of the stabilizing sleeve 9, a sliding rail 11 which is in sliding fit with the sliding groove is formed in the outer wall of the first pipeline, a stabilizing groove 12 is formed in the right end of the stabilizing sleeve, an annular step 13 is formed in the outer wall of the second pipeline, connecting grooves 14 which correspond to the stabilizing grooves one to one are formed in the annular step, and stabilizing blocks 15 are rotatably connected in the connecting grooves through rotating shafts; the sliding groove and the sliding rail are of dovetail structures; the stabilizing groove and the stabilizing block are of T-shaped structures.

When two pipes are assembled, the second pipeline is connected to the first pipeline through the connecting pipe threads, then the stabilizing sleeve is slid to the annular step, and the stabilizing block is turned over and pressed into the stabilizing groove, so that on one hand, relative rotation between the first pipeline and the second pipeline can be prevented, the stability of threaded connection is improved, and the connection looseness of the two pipes is avoided; secondly, the stable cover suit can share the radial pressure of connecting pipe between first pipeline and second pipeline, avoids the connecting pipe fracture.
