[0023] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0024] like Figures 1 to 4 As shown, the utility model is a PE conduit that is easy to install, including a PE conduit body 1, with a first splicing ring 2 and a second splicing ring 3 provided at both ends of the PE conduit body 1. When adjacent PE conduit bodies 1 are connected end to end, the adjacent first splicing rings 2 and second splicing rings 3 are spliced together, and a connecting assembly 4 connecting the first splicing rings 2 and the second splicing rings 3 is provided between the spliced first splicing rings 2 and the second splicing rings 3.
[0025] The pre-designed first splicing ring 2 and second splicing ring 3 structures allow adjacent PE conduits to be easily connected via the splicing ring structure without the need for complex hot-melt welding steps, making on-site installation more convenient and faster, and reducing dependence on special tools or equipment. Since installation becomes simpler and faster, it helps shorten the construction period and reduce labor costs. The splicing ring structure helps ensure accurate alignment of the PE conduit connections, avoiding problems such as axis misalignment and end surface unevenness that may occur in traditional hot-melt welding, effectively preventing cracking or leakage at the pipe connections due to improper welding, and improving the long-term stability and reliability of the entire cable laying system.
[0026] When the adjacent first splicing ring 2 and the second splicing ring 3 are spliced together, a plug-in groove 5 is provided at one end of the first splicing ring 2 close to the matching second splicing ring 3, and a plug-in plate 6 corresponding to the plug-in groove 5 is provided at one end of the second splicing ring 3 close to the matching first splicing ring 2. The plug-in groove 5 and the plug-in plate 6 are connected by a connecting component 4; by inserting the plug-in plate 6 into the plug-in groove 5, it is ensured that the first splicing ring 2 and the second splicing ring 3 can be accurately aligned and tightly fitted; the two splicing rings are fixed together by the connecting component 4 to ensure the stability and sealing of the connection.
[0027] As a preferred embodiment of the above embodiment, the connecting component 4 includes a limiting groove 7, a slide groove 8, a slider 9 and a first spring 10. The limiting groove 7 is arranged on the inner wall of the first splicing ring 2, and the limiting groove 7 is connected to the plug-in groove 5. The slide groove 8 is arranged on the outer wall of the second splicing ring 3. A slider 9 is slidably connected in the slide groove 8, and the slider 9 can move along the slide groove 8 toward the limiting groove 7. A first spring 10 is arranged between the opposite ends of the slide groove 8 and the slider 9; by inserting the plug-in board 6 into the plug-in groove 5, the slider 9 is squeezed by the second splicing ring 3 to move toward the inside of the slide groove 8, and the first spring 10 is forced to shrink. After the plug-in board 6 is fully inserted, the first spring 10 releases the pressure and pushes the slider 9 toward the side of the limiting groove 7 until the slider 9 enters the limiting groove 7. At this time, the slider 9 is kept in the limiting groove 7 by the pressure of the first spring 10, so that the first splicing ring 2 and the second splicing ring 3 are locked, simplifying the installation process; the cooperation between the slider 9 and the limiting groove 7 ensures the stability of the connection and improves the connection quality.
[0028] As a preferred embodiment of the above, a pressing groove 11 is provided on the limiting groove 7 and is connected to the limiting groove 7, and a pressing rod 12 is slidably connected in the pressing groove 11, one end of the pressing rod 12 extends to the outside, and the other end of the pressing rod 12 abuts against the slider 9.

[0029] As a preferred embodiment of the above embodiment, a limit plate 14 is provided at both ends of the pressing rod 12, and the outer diameter of the limit plate 14 is larger than the pressing rod 12; the limit plate 14 limits the movement range of the pressing rod 12 in the pressing groove 11 and ensures that the pressing rod 12 will not completely separate from the pressing groove 11, thereby improving the stability and safety of the unlocking mechanism.
[0030] As a preferred embodiment of the above, a slope 15 is provided on the slider 9, and the slope 15 is a structure that gradually slopes downward from one end close to the first spring 10 to the end away from the first spring 10; during the process of inserting the plug-in board 6 into the plug-in slot 5, the slope 15 gradually contacts the second splicing ring 3, so that the slider 9 is pressed into the slide groove 8, ensuring the smooth movement of the plug-in board 6.
[0031] As a preferred embodiment of the above, a third spring 16 is provided in the plug-in slot 5, and a pressure plate 17 is provided at the bottom of the third spring 16. When the plug-in board 6 is inserted into the plug-in slot 5, the pressure plate 17 abuts against the plug-in board 6; when the plug-in board 6 is fully inserted, the pressure plate 17 squeezes the plug-in board 6 under the action of the third spring 16, so that the bottom of the slider 9 is in close contact with the limit slot 7, thereby improving the stability and reliability of the connection.
[0032] As a preferred embodiment of the above, a plurality of positioning blocks 18 are provided on the outer wall of the plug-in board 6, and a positioning groove 19 corresponding to the positioning blocks 18 is provided on the inner wall of the plug-in slot 5; the precise alignment between the plug-in board 6 and the plug-in slot 5 is ensured by the cooperation of the positioning blocks 18 and the positioning grooves 19, thereby preventing the occurrence of cheapness and improving the accuracy of the connection.
[0033] As a preferred embodiment of the above, a fitted wear-resistant sleeve is provided on the outside of the PE conduit body 1, and a fitted protective pad is provided inside the PE conduit body 1; the wear-resistant sleeve improves the resistance of the PE conduit to external wear and extends the service life of the conduit; the protective pad can provide additional protection for the cables passing through the inside, preventing the cables from being damaged by direct contact with the conduit, thereby affecting the normal operation of the cables.
[0034] As a preference of the above embodiment, a waterproof sealing ring is provided between the splicing gap of the first splicing ring 2 and the second splicing ring 3; the waterproof sealing ring can be made of rubber or other elastic materials with good sealing properties to improve the waterproof performance of the connection and prevent moisture from penetrating into the interior of the conduit, thereby protecting the cable from damage.
[0035] When the PE conduit of the present invention is easy to install, the two PE conduit bodies 1 are first connected end to end, so that the first splicing ring 2 and the second splicing ring 3 are aligned with each other, and the positioning block 18 is aligned with the positioning groove 19; the plug-in plate 6 on the second splicing ring 3 is inserted into the plug-in groove 5 of the first splicing ring 2. During the insertion process, the slope 15 contacts the second splicing ring 3, the slider 9 is pressed to move toward the inside of the slide groove 8, and the first spring 10 contracts; when the plug-in plate 6 is fully inserted, the first spring 10 releases the pressure, the slider 9 moves into the limit groove 7 to achieve automatic locking, and the pressure plate 17 squeezes the plug-in plate 6 under the action of the third spring 16 to ensure that the bottom of the slider 9 abuts against the limit groove 7; when disassembly is required, by pressing one end of the pressing rod 12, the pressing rod 12 moves along the pressing groove 11, pushing the slider 9 to move toward the slide groove 8, thereby disengaging the slider 9 from the limit groove 7; moving the PE conduit body 1 in the opposite direction of connection, the lock between the first splicing ring 2 and the second splicing ring 3 is released, and the conduit can be easily separated.
