Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

As shown in fig. 1 to 4, a socket pipe of an embodiment includes a pipe body 1, a socket structure and a socket structure, the socket structure and the socket structure are respectively disposed at a first end and a second end of the pipe body 1, the socket structure includes a plurality of first protrusions 21 disposed at intervals, the first protrusions 21 are disposed around an outer wall of the pipe body 1, the socket structure includes a plurality of second protrusions 31 disposed at intervals, the second protrusions 31 are disposed around an inner wall of the pipe body 1, a first gap 110 is formed between two adjacent second protrusions 31, the socket structure further includes a limiting groove 120, the limiting groove 120 is disposed at a side of the second protrusion 31 near a center of the pipe body 1, the first protrusion 21 can pass through the first gap 110 and be screwed into the limiting groove 120, the first projection 21 abuts against the second projection 31 on the side close to the center of the tube body 1, and the first projection 21 is fixed in the limit groove 120.

The spigot structure of the socket pipe of the embodiment comprises a plurality of first lugs 21 arranged at intervals, the socket structure comprises a plurality of second lugs 31 arranged at intervals and a limiting groove 120, when the pipeline connection operation of two socket pipes is carried out, the first lug 21 of one socket pipe can pass through a first gap 110 between two adjacent second lugs 31 of the other socket pipe without resistance, after the first lug 21 enters the limiting groove 120, the first lug 21 can be rotated to one side of the second lug 31 close to the center of the pipe body 1 and abutted against the second lug 31 by rotating one of the socket pipes, and only after the socket pipe is rotated for a certain angle, the first lug 21 can be separated from the limiting groove 120, so that the first lug 21 is fixed in the limiting groove 120. Therefore, the utility model discloses a connection process of socket pipe is convenient laborsaving, can improve the efficiency of pipe connection operation.

As shown in fig. 4 and 5, the socket structure further includes a first seal ring 32, the first end of the pipe body 1 forms a stepped structure, the second end of the pipe body 1 forms a stepped hole structure, the first seal ring 32 is disposed on a stepped surface of the stepped hole structure, and the first end of one pipe body 1 can be inserted into the second end of another pipe body 1 such that an end surface of the first end abuts against the first seal ring 32. First sealing washer 32 plays sealed effect, and after spacing recess 120 was gone into to first lug 21 card, the terminal surface of the first end of pipe body 1 can compress tightly first sealing washer 32, realizes better sealed effect. The first seal ring 32 is preferably made of an elastic material such as rubber or silicone.

Furthermore, the thickness of the first protrusion 21 is smaller than the width of the limiting groove 120, and the first sealing ring 32 enables the first protrusion 21 to tightly abut against the second protrusion 31. As shown in fig. 5, since the thickness of the first protrusion 21 is smaller than the width of the limiting groove 120, after the two socket pipes are connected, a second gap 140 is formed between the first protrusion 21 and the groove wall of the limiting groove 120, so that the first protrusion 21 is pressed against the second protrusion 31 by the elastic force of the first sealing ring 32, thereby obtaining a better fixing effect. When two socket pipes are connected, firstly, the end face of the first end of one socket pipe extrudes the first sealing ring 32, so that the first sealing ring 32 deforms and stores certain elastic potential energy, then the socket pipe is kept under pressure and rotated, so that the first bump 21 is clamped into the limiting groove 120, and then after the socket pipe is loosened, the first sealing ring 32 can enable the first bump 21 to slightly displace and tightly press the second bump 31, and the first bump 21 needs to displace, so that a certain space must be reserved, and therefore, the thickness of the first bump 21 needs to be smaller than the width of the limiting groove 120.

As shown in fig. 2, 4 and 5, the first protrusion 21 includes a protrusion body 211 and a limiting protrusion 212, the first limiting protrusion 212 is disposed on one side of the first protrusion 21 abutting against the second protrusion 31, a fixing groove 130 is disposed on one side of the second protrusion 31 abutting against the first protrusion 21, and the limiting protrusion 212 can be snapped into the fixing groove 130. By providing the position-limiting protrusion 212 and the fixing groove 130, the first protrusion 21 can be more stably fixed in the position-limiting groove 120. If the first projection 21 is to be disengaged from the retaining groove 120, it is necessary to first press the end surface of the first end of the pipe body 1 against the first gasket 32 to disengage the retaining protrusion 212 from the retaining groove 130, and then rotate the pipe body 1, so that the first projection 21 can be more effectively retained.

Preferably, the limiting protrusion 212 is a segment-shaped protrusion, and the fixing groove 130 is a segment-shaped groove. Even if the limiting protrusion 212 is not completely aligned with the fixing groove 130, the limiting protrusion 212 can slide into the fixing groove 130, and the inner state of the pipeline cannot be observed in the pipeline connecting process due to the fact that common pipelines are not transparent, and the requirement for connecting precision in the pipeline connecting process is effectively reduced through the arrangement.

Further, the socket structure further comprises a second sealing ring 22, the second sealing ring 22 is arranged on a step surface of the step structure at the first end of the pipe body 1, and the end surface of the second end of the pipe body 1 can be abutted to the second sealing ring 22. As shown in fig. 5, since the first protrusion 21 is pressed in and then retreated for a distance in the process of pipe connection, similar to the reason for the existence of the second gap 140, after the pipe connection is completed, a third gap 150 exists between the step surface of the step structure at the first end of the pipe body 1 and the end surface of the second end of the pipe body 1, and the second sealing ring 22 can fill the third gap 150, thereby further enhancing the sealing effect. In addition, the second sealing ring 22 can also be used as a buffer to prevent direct collision between two sections of socket pipes.

The end face of the second end of the pipe body 1 is spaced from the step face of the step structure of the first end of the pipe body 1 by a set distance which cannot be too large or too small. In order not to hinder the compression of the first sealing ring 32 by the first protrusion 21, the set distance should not be smaller than the difference between the width of the limiting groove 120 and the thickness of the first protrusion 21, and of course, the set distance should not be too large, so as to avoid the increase of the sealing difficulty of the second sealing ring 22 due to the too wide width of the third gap 150.

Preferably, the number of the first protrusions 21 and the second protrusions 31 is at least three, and the first protrusions 21 are disposed on the outer wall of the pipe body 1 at equal intervals, and the second protrusions 31 are disposed on the inner wall of the pipe body 1 at equal intervals. After the socket pipe is connected, the acting force of the first convex blocks 21 and the acting force of the second convex blocks 31 on the pipe body 1 can be dispersed more by the first convex blocks 21 and the second convex blocks 31 with a larger number, which is beneficial to improving the stability and the reliability of the connection.

In the present embodiment, the number of the first bumps 21 and the second bumps 31 is preferably eight.
