Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of plastic pipes, in particular to a trenchless PE plastic socket jacking pipe. Background Art
[0002] Urban drainage pipe network is an important part of urban infrastructure, and its operation is directly related to the normal use of other urban engineering facilities. Problems in urban drainage pipe network not only cause serious pollution and damage to the urban environment, seriously affect the appearance of the city, but also pose a major safety hazard, bringing great inconvenience to citizens' lives and travel.
[0003] In the prior art, the laying length of the pipeline is long and multiple pipelines need to be used for plug-in connection, thereby extending the length of the pipeline. The following problems exist in the process of plugging adjacent pipelines:
[0004] When the pipes are plugged in, a sealing ring needs to be sleeved on the outside of one of the pipes. However, during the pipe plugging process, the sealing ring is easily misaligned due to the friction between the outside of the sealing ring and the inner wall of the other pipe, thereby affecting the sealing effect. Utility Model Content
[0005] In order to solve the deficiencies of the prior art, the utility model provides a trenchless PE plastic socket jacking pipe, which is realized by the following technical solutions:
[0006] A trenchless PE plastic socket jacking pipe comprises a connecting pipe, one end of which is integrally fixedly provided with a socket joint, the other end of which is integrally fixedly provided with a connector, a sealing ring is arranged in the socket joint, and a self-locking mechanism is arranged in the connecting pipe.
[0007] The self-locking mechanism comprises an annular protrusion, a plurality of evenly distributed annular protrusions are fixedly installed in the socket interface, and a plurality of annular grooves corresponding to the annular protrusions are formed on the outer periphery of the connecting head.
[0008] A limiting groove is provided on the inner side of the socket joint, and a sealing ring is movably installed in the limiting groove.
[0009] The inner wall of the socket joint is provided with a plurality of evenly distributed anti-slip grooves.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] 1. Both ends of the connecting pipe in this device are equipped with socket joints and connectors respectively. This design facilitates the rapid assembly and disassembly of two adjacent connecting pipes. At the same time, the overall strength and stability of the structure are enhanced through integrated fixed installation.
[0012] 2. The self-locking mechanism is formed by the cooperation between the annular protrusion and the annular groove, which ensures the firmness of the connection between the two connecting pipes. When the two connecting pipes are butt-jointed, the annular protrusion and the annular groove engage with each other, effectively preventing accidental disengagement and improving the safety of use.
[0013] 3. The sealing ring is located in the limit groove of the socket joint, which can not only effectively prevent dislocation, but also be clamped by the two when the connector is inserted, forming a reliable sealing barrier to prevent liquid leakage and improve the sealing performance.

[0020] Embodiment: A trenchless PE plastic socket jacking pipe
[0021] like Figure 1 - As shown in Figure 4, a trenchless PE plastic socket jacking pipe, the specific structure of which includes:
[0022] A connecting pipe 1, one end of which is integrally fixedly mounted with a socket joint 2, the other end of which is integrally fixedly mounted with a connector 3, a sealing ring 4 with a T-shaped cross-section is provided in the socket joint 2, and a self-locking mechanism is provided in the connecting pipe 1.
[0023] The self-locking mechanism comprises an annular protrusion 5 , a plurality of evenly distributed annular protrusions 5 are fixedly installed in the socket joint 2 , and a plurality of annular grooves 6 corresponding to the annular protrusions 5 are formed on the outer periphery of the connector 3 .
[0024] When the device is in use, during the process of docking two connecting pipes 1, the connector 3 of one of the connecting pipes 1 is inserted into the socket interface 2 of the other connecting pipe 1. During the process of docking the two connecting pipes 1, the annular protrusions 5 are respectively engaged with the corresponding annular grooves 6, thereby achieving a stable connection between the two connecting pipes 1 and preventing them from falling off during use.
[0025] A limiting groove 7 is provided on the inner side of the socket joint 2 , and a sealing ring 4 is movably installed in the limiting groove 7 .
[0026] When this structural design is in use, the sealing ring 4 is installed through the limit groove 7, which can avoid the sealing ring 4 from being misplaced during the docking process of the two connecting pipes 1, thereby improving the sealing effect of the device; during the docking process of the two connecting pipes 1, after the connecting head 3 of one of the connecting pipes 1 is inserted into the socket joint 2 of the other connecting pipe 1, the connecting head 3 and the corresponding socket joint 2 can clamp and fix the sealing ring 4, and the sealing ring 4 fits tightly with the end of the connecting head 3 and the inner side of the socket joint 2, thereby ensuring the sealing effect of the device.
[0027] The inner wall of the socket joint 2 is provided with a plurality of evenly distributed anti-slip grooves 8 .
[0028] When this structural design is in use, when connecting two connecting pipes 1, plastic pipe adhesive is applied inside the socket joint 2, and a portion of the adhesive can be stored in the anti-slip groove 8, so that when the connecting head 3 is inserted into the corresponding socket joint 2, the plastic pipe adhesive will not be completely pushed into the inner side of the socket joint 2, thereby ensuring the bonding effect of the plastic pipe adhesive.
[0029] Working principle:
[0030] When the device is in use, two adjacent connecting pipes 1 are plugged together, and the connecting head 3 of one of the connecting pipes 1 is inserted into the socket interface 2 of the other connecting pipe 1. During the plugging process, the annular protrusion 5 and the annular groove 6 are automatically engaged to form a self-locking function. At the same time, the limiting groove 7 fixes the sealing ring 4, which can ensure that the two connecting pipes 1 do not shift when docking, thereby enhancing the sealing performance of the device.
[0031] In the interpretation of the present invention, it should be noted that the terminology indicating the orientation is only for the convenience of description and understanding, and is not the only limitation on the installation position of the specific technical features, and does not exclude other possible installation methods.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
