Description

Technical Field

[0001] This utility model relates to the field of communication tube technology, specifically to an MPP communication tube that is easy to install. Background Technology

[0002] MPP power and communication pipes are a new type of plastic pipe made primarily of modified polypropylene (PP) using a special formula and processing technology. MPP power and communication pipes are widely used in the power and construction industries.

[0003] Chinese patent document CN211296029U discloses an easy-to-install MPP power communication tube, including a communication tube and a connecting box. A fixed gear is fixedly connected to the outer surface of the communication tube. A drive cavity is opened inside the connecting box. A fixed block is fixedly connected to the inner top wall of the drive cavity. A sliding rod is fixedly connected to one side of the fixed block. A sliding block is slidably connected to the outer surface of the sliding rod. A first bracket is fixedly connected to the bottom of the sliding block. A connecting rod is fixedly hinged to the bottom of the first bracket by a pin. A second bracket is fixedly hinged to the other end of the connecting rod by a pin. A movable plate is fixedly connected to the bottom of the second bracket. A first spring is sleeved on the outer surface of the sliding rod.

[0004] However, in the above solution, the two communication tubes can only be connected by meshing the movable rack with the fixed gear in the connecting box. However, since a sealing layer is required to seal the connection between the two communication tubes, the two communication tubes need to be squeezed against the sealing layer during use. Only after the sealing layer is compressed can the movable rack mesh with the fixed gear, making the installation and connection of the communication tubes inconvenient. Utility Model Content

[0021] Example 1

[0022] like Figure 1-3 As shown, the present invention proposes an easy-to-install MPP communication tube, which includes a tube body 1, a connecting ring 2, a sleeve 5, and a limiting ring 9.

[0023] The connecting ring 2 is installed on the outer side of one end of the pipe body 1, and the outer circular surface of the connecting ring 2 is provided with an external thread 3 for connecting to the end of another pipe body 1 in the use state;

[0024] The limiting ring 9 is located at the other end of the tube body 1 and its end face is flush with the end face of the tube body 1;

[0025] The sleeve 5 is installed at the other end of the tube body 1 and wraps around the outside of the connecting ring 2 and the limiting ring 9. The outside of the sleeve 5 is provided with a bolt 6 for inserting the sleeve 5 through the side of the connecting ring 2 in the use state. The bolt 6 is used to connect the sleeve 5 to the connecting ring 2 in use, so as to limit the position of the sleeve 5 and prevent the sleeve 5 from reversing. In use, both ends of the tube body 1 can be spiral corrugated, and the dimensions of the two ends of the tube body 1 are arranged to match, so that the two tube bodies 1 are connected by spiral corrugation (not shown in the figure, and spiral corrugated tube is existing technology and will not be described in detail here), and then the two tube bodies 1 are connected to each other by bolt 6 for installation and fixation.

[0026] In an optional embodiment, both the sleeve 5 and the connecting ring 2 are provided with threaded holes 4 on their sides. The bottom end of the bolt 6 is inserted into the threaded hole 4 and connected to the sleeve 5 and the connecting ring 2. This is used to connect the bolt 6 to the connecting ring 2 and the sleeve 5 inside the threaded hole 4 during use, and to fix the sleeve 5 to the outside of the connecting ring 2 by the cooperation between the bolt 6 and the threaded hole 4.

[0027] In an optional embodiment, the central dimension of the sleeve 5 is greater than the outer dimension of the tube body 1 and less than the outer dimension of the limiting ring 9, so as to allow the sleeve 5 to rotate on the outside of the tube body 1, and to allow the sleeve 5 to be connected to the connecting ring 2 through the external thread 3.

[0028] In this embodiment, by placing one end of the two tubes 1 coaxially and abutting each other, while moving the sleeve 5 toward the connecting ring 2 and rotating the sleeve 5, the sleeve 5 is connected to the external thread 3 and wrapped around the outside of the connecting ring 2, and the two threaded holes 4 are placed coaxially, and the bolt 6 is inserted into the threaded hole 4, so that the bolt 6 fixes the sleeve 5 on the connecting ring 2, so that the sleeve 5 and the connecting ring 2 are tightly connected, and the ends of the two tubes 1 are tightly fitted and connected, ensuring the stability and sealing of the overall structure.

[0029] Example 2

[0030] like Figure 3 As shown, this utility model proposes an easy-to-install MPP communication tube. Compared with the first embodiment, the difference in this embodiment is that the cross-sectional projection shape of the sleeve 5 is L-shaped, and the inner side of the sleeve 5 is provided with a threaded groove 10. When the sleeve 5 and the connecting ring 2 are installed together, the external thread 3 is accommodated in the threaded groove 10.

[0031] In this embodiment, by providing a threaded groove 10 on the inner side of the sleeve 5 and matching the size of the threaded groove 10 with the size of the external thread 3, the external thread 3 is securely embedded in the threaded groove 10, thereby enhancing the connection strength, simplifying the installation steps, and improving the overall structural stability.

[0032] Example 3

[0033] like Figure 3 As shown, this utility model proposes an easy-to-install MPP communication tube. Compared with Embodiment 1, the difference in this embodiment is that a convex ring 7 is provided on one end face of the tube body 1, and a connecting groove 8 is provided on the other end face of the tube body 1. When the two tube bodies 1 are installed coaxially, the connecting groove 8 is accommodated in the convex ring 7, which increases the connection area of ​​the two tube body 1 ends during use, thereby making the connection of the two tube bodies 1 tighter and ensuring that the two tube bodies 1 are placed coaxially, thus ensuring a stable connection and improving the overall sealing performance.

[0034] In an optional embodiment, a gasket 11 is provided on the side of the limiting ring 9. The gasket 11 is connected to the inner bottom end of the sleeve 5. It is used to fill the gap between the sleeve 5 and the limiting ring 9 by the elastic deformation of the gasket 11 during use, so as to ensure the sealing effect, prevent the intrusion of external impurities, and improve the durability and reliability of the overall structure.

[0035] In an optional embodiment, the side of the limiting ring 9 is provided with an installation groove 13 and the side of the gasket 11 is provided with a connecting block 12. When the gasket 11 and the limiting ring 9 are installed together, the connecting block 12 is accommodated in the installation groove 13, which is used to limit the installation of the gasket 11 during use, further optimize the sealing effect, and improve the stability and service life of the overall structure.

[0036] In this embodiment, the two tubes 1 are placed coaxially by the cooperation of the convex ring 7 and the connecting groove 8, and the end faces of the two tubes 1 are tightly fitted, increasing the contact area and ensuring a firm connection. At the same time, the precise cooperation between the connecting block 12 and the mounting groove 13 ensures that the gasket 11 is fixed in position during installation, avoiding displacement. When the sleeve 5 is connected to the connecting ring 2, a seal is formed between the sleeve 5 and the limiting ring 9, ensuring the stable operation of the communication tube in complex environments.

[0037] In this invention, by abutting one end of two tubes 1 and inserting the connecting groove 8 into the convex ring 7, the two tubes 1 are placed coaxially. At the same time, the sleeve 5 is moved towards the limiting ring 9, so that the sleeve 5 wraps around the outer side of the end of the connecting ring 2. The sleeve 5 is rotated by the threaded groove 10 on the inner side of the sleeve 5 and the external thread 3 is accommodated in the threaded groove 10. The sleeve 5 wraps around the outer side of the connecting ring 2, and the sleeve 5 and the connecting ring 2 are tightly connected by the limiting ring 9. At the same time, the two threaded holes 4 are placed coaxially, and the bolt 6 is inserted into the threaded hole 4, so that the bolt 6 fixes the sleeve 5 on the connecting ring 2. This makes the connection of the two tubes 1 more stable and ensures the stability and sealing of the overall structure.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
