Description

Technical Field

[0001] The utility model relates to the technical field of communication pipes, in particular to a PE communication pipe used for municipal engineering construction. Background Art

[0002] Communication pipe is a piping system used to protect and manage communication cables.

[0003] In order to facilitate production and transportation, the length of communication pipes is often fixed. In order to adapt to the laying of communication cables in various situations, multiple communication pipes need to be connected. When two sections of communication pipes are connected, in the existing technology, a sheath is often used to cover the connection between the two sections of communication pipes, and then iron wire is tied on the outside of the sheath to achieve the connection of the two sections of communication pipes. However, the longer communication pipe formed by this connection method cannot have a large range of shaking and cannot cause a large tension in the axial direction. Otherwise, the sheath will loosen or even fall off. That is, the two sections of communication pipes in the existing technology cannot withstand a large tension in the axial direction after being connected by the sheath. Utility Model Content

[0004] The purpose of the utility model is to provide a PE communication pipe for municipal engineering construction to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PE communication pipe for municipal engineering construction, comprising: a communication pipe and a connecting sleeve, the end of the communication pipe is provided with four spiral arc grooves, the inner side of the four spiral arc grooves is provided with a movable groove, the connecting sleeve is provided with a sliding groove, a limiting ring is slidingly arranged in the sliding groove, and four guide protrusions that cooperate with the four spiral arc grooves are fixedly connected to the inner side of the limiting ring. As the communication pipe is pushed into the connecting sleeve, the guide protrusion slides along the spiral arc groove, driving the limiting ring to rotate and finally disengaging from the spiral arc groove to clamp the communication pipe in the connecting sleeve.

[0006] Furthermore, a plurality of slots are provided in the slide groove near the outlet of the connecting sleeve, and a plurality of blocks corresponding to the slots are fixedly connected to the side of the limiting ring near the outlet of the connecting sleeve, and the size of the slots is larger than the size of the blocks.

[0007] Furthermore, a first permanent magnet is embedded in the inner wall of the clamping slot on the side close to the outlet of the connecting sleeve, and a second permanent magnet is embedded in the top of the clamping block.

[0008] Furthermore, a partition ring is fixedly connected to the inner side of the middle portion of the connecting sleeve.

[0009] Furthermore, sealing rings are fixedly connected to both ends of the connecting sleeve near the outlet of the connecting sleeve.

[0010] In the above technical solution, the utility model provides a PE communication pipe for municipal engineering construction with the following beneficial effects:

[0011] The utility model inserts the communication tube into the connecting sleeve after the guide protrusion is aligned with the spiral arc groove. As the communication tube is advanced, the limit ring rotates in the sliding groove until the guide protrusion is disengaged from the spiral arc groove. The section of the communication tube with the spiral arc groove is completely inserted into the inner side of the limit ring. Then the communication tube is rotated so that the guide protrusion and the spiral arc groove are no longer aligned, thereby realizing the axial clamping connection between the communication tube and the connecting sleeve, thereby improving the ability of the communication tube and the connecting sleeve to withstand axial tension, thereby greatly improving the application range of the communication tube.

[0012] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments.

[0020] See also Figure 1-Figure 2 A PE communication pipe for municipal engineering construction includes: a communication pipe 1 and a connecting sleeve 2. Four spiral arc grooves 12 are opened at the end of the communication pipe 1, and a movable groove 11 is opened on the inner side of the four spiral arc grooves 12. A sliding groove 22 is opened in the connecting sleeve 2. A limit ring 3 is slidingly arranged in the sliding groove 22. Four guide protrusions 31 that cooperate with the four spiral arc grooves 12 are fixedly connected to the inner side of the limit ring 3. As the communication pipe 1 is pushed into the connecting sleeve 2, the guide protrusion 31 slides along the spiral arc groove 12, driving the limit ring 3 to rotate and finally disengage from the spiral arc groove 12 to clamp the communication pipe 1 in the connecting sleeve 2.

[0021] Specifically, the axial length of the slide groove 22 is greater than the axial length of the limit ring 3. After the guide protrusion 31 is aligned with the spiral arc groove 12, the communication tube 1 is inserted into the connecting sleeve 2. As the communication tube 1 is advanced, the limit ring 3 rotates in the slide groove 22 until the guide protrusion 31 is disengaged from the spiral arc groove 12. A section of the spiral arc groove 12 on the communication tube 1 is completely inserted into the inner side of the limit ring 3. Then, the communication tube 1 is rotated so that the guide protrusion 31 and the spiral arc groove 12 are no longer aligned, thereby realizing the axial clamping of the communication tube 1 and the connecting sleeve 2, thereby improving the ability of the communication tube 1 and the connecting sleeve 2 to withstand axial tension, thereby greatly improving the scope of application of the communication tube 1.

[0022] Furthermore, a plurality of slots 23 are provided in the slide groove 22 near the outlet of the connecting sleeve 2 , and a plurality of blocks 32 corresponding to the slots 23 are fixedly connected to the limiting ring 3 near the outlet of the connecting sleeve 2 , and the size of the slots 23 is larger than that of the blocks 32 .

[0023] Specifically, refer to Figure 1 and Figure 2 There are four card slots 23 in the slide 22. The card slot 23 is located in the middle of the slide 22 and the nearest exit of the connecting sleeve 2, and is distributed in an array. Four card blocks 32 are fixedly connected to the side of the limiting ring 3. The arrangement direction of the card blocks 32 is the same as that of the card slots 23, and they are also distributed in an array. The card blocks 32 correspond to the card slots 23 one by one, and the size of the card slots 23 is larger than that of the card blocks 32, which is sufficient to achieve that after the card blocks 32 are engaged with the card slots 23, the limiting ring 3 can still rotate to a certain extent in the connecting sleeve 2.

[0024] Furthermore, a first permanent magnet 25 is embedded in the inner wall of the clamping groove 23 near the outlet of the connecting sleeve 2 , and a second permanent magnet 33 is embedded in the top of the clamping block 32 .

[0025] Specifically, refer to Figure 1 and Figure 2 By setting the first permanent magnet 25 and the second permanent magnet 33, when the limit ring 3 is in the slide groove 22, under the mutual attraction of the first permanent magnet 25 and the second permanent magnet 33, the clamping block 32 will be inserted into the clamping groove 23, so that the limit ring 3 is limited by the connecting sleeve 2, preventing the limit ring 3 from rotating significantly.

[0026] In this utility model, reference is made to Figure 1 and Figure 2 When the communication tube 1 is inserted into the connecting sleeve 2, as the communication tube 1 is advanced, the communication tube 1 will overcome the magnetic force generated between the first permanent magnet 25 and the second permanent magnet 33 to push the limit ring 3 to slide into the connecting sleeve 2, so that the locking groove 23 and the blocking block 32 are disengaged. Subsequently, the guide protrusion 31 is aligned with the spiral arc groove 12. As the communication tube 1 continues to advance, the guide protrusion 31 slides in the spiral arc groove 12, so that the limit ring 3 rotates in the slide groove 22 until the guide protrusion 31 is disengaged from the spiral arc groove 12. The limit ring 3 is located at the position of the movable groove 11. Under the action of the magnetic force generated between the first permanent magnet 25 and the second permanent magnet 33, the blocking block 32 is re-inserted into the locking groove 23, so that the limit ring 3 cannot rotate at a large angle, thereby preventing the communication tube 1 from separating from the connecting sleeve 2.

[0027] Furthermore, a partition ring 21 is fixedly connected to the inner side of the middle portion of the connecting sleeve 2 .

[0028] Specifically, the partition ring 21 can be made of rubber, which can achieve good sealing between the two communication pipes 1 inserted on both sides of the connecting sleeve 2.

[0029] Furthermore, sealing rings 24 are fixedly connected to both ends of the interior of the connecting sleeve 2 near the outlet of the connecting sleeve 2 .

[0030] Specifically, by embedding sealing rings 24 on both sides of the connecting sleeve 2 near the outlet position, the sealing between the communication pipe 1 and the connecting sleeve 2 is further strengthened.

[0031] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
