The laying length of the pipeline in the prior art is longer, and a plurality of pipelines are required to be used for plug connection, so that the length of the pipeline is prolonged, and the following problems exist in the plug connection process of adjacent pipelines:

When the pipeline is spliced, the sealing ring is required to be sleeved outside one of the pipelines, however, in the pipeline splicing process, the sealing ring is easy to misplace due to the mutual friction between the outer part of the sealing ring and the inner wall of the other pipeline, so that the sealing effect is influenced.

Disclosure of utility model

In order to solve the defects in the prior art, the utility model provides a trenchless PE plastic socket pipe, which is realized by the following technical scheme:

The utility model provides a non-excavation PE plastics socket pipe, includes the connecting pipe, the one end integral type fixed mounting of connecting pipe has the socket joint, the other end integral type fixed mounting of connecting pipe has the connector, be equipped with the sealing washer in the socket joint, be equipped with self-locking mechanism in the connecting pipe.

The self-locking mechanism comprises annular protrusions, a plurality of annular protrusions which are uniformly distributed are fixedly arranged in the socket, and a plurality of annular grooves which correspond to the annular protrusions one by one are formed in the periphery of the connector.

The inner side of the socket joint is provided with a limiting groove, and a sealing ring is movably installed in the limiting groove.

The inner wall of socket joint has seted up a plurality of evenly distributed's anti-skidding groove.

Compared with the prior art, the utility model has the beneficial effects that:

1. The socket joint and the connector are respectively arranged at the two ends of the connecting pipe in the device, the design is convenient for the rapid assembly and disassembly of two adjacent connecting pipes, and meanwhile, the integral strength and the stability of the structure are enhanced through the integrated fixed installation.

2. The self-locking mechanism is formed by the cooperation of the annular bulge and the annular groove, so that the connection firmness of the two connecting pipes is ensured. When two connecting pipes are in butt joint, the annular bulge is mutually meshed with the annular groove, so that accidental detachment is effectively prevented, and the use safety is improved.

3. The sealing washer is located the spacing inslot of socket joint, not only can effectively prevent the dislocation, when the connector inserts moreover, can be pressed from both sides tightly by both, forms reliable sealed barrier, prevents that liquid from leaking, has promoted sealing performance.

Embodiment of the PE plastic socket pipe without excavation

As shown in fig. 1-4, a trenchless PE plastic socket pipe comprises the following specific structures:

The connecting pipe 1, the one end integral type fixed mounting of connecting pipe 1 has socket joint 2, the other end integral type fixed mounting of connecting pipe 1 has connector 3, be equipped with the sealing washer 4 that the cross-section is the T type in the socket joint 2, be equipped with self-locking mechanism in the connecting pipe 1.

The self-locking mechanism comprises annular protrusions 5, a plurality of evenly distributed annular protrusions 5 are fixedly arranged in the socket joint 2, and a plurality of annular grooves 6 which are in one-to-one correspondence with the annular protrusions 5 are formed in the periphery of the connector 3.

When the device is used, in the butt joint process of the two connecting pipes 1, the connector 3 of one connecting pipe 1 is inserted into the socket joint 2 of the other connecting pipe 1, and in the butt joint process of the two connecting pipes 1, the annular protrusions 5 are respectively clamped with the corresponding annular grooves 6, so that the stable connection of the two connecting pipes 1 is realized, and the falling of the two connecting pipes 1 in the use process is prevented.

The inner side of the socket joint 2 is provided with a limit groove 7, and a sealing ring 4 is movably arranged in the limit groove 7.

When the structure design is used, the sealing ring 4 is installed through the limiting groove 7, dislocation of the sealing ring 4 in the butt joint process of the two connecting pipes 1 can be avoided, the sealing effect of the device is improved, after the connector 3 of one connecting pipe 1 is inserted into the socket joint 2 of the other connecting pipe 1 in the butt joint process of the two connecting pipes 1, the connector 3 and the corresponding socket joint 2 can clamp and fix the sealing ring 4, and the sealing ring 4 is tightly attached to the end part of the connector 3 and the inner side of the socket joint 2, so that the sealing effect of the device is ensured.
