[0038] See also Figures 1-6A PE pipe that is easy to connect includes a butt joint 2 for connecting a PE pipe body 1. The butt joint 2 includes two telescopic sleeves 201 and a telescopic tube 202 arranged between the two telescopic sleeves 201. The two telescopic sleeves 201 are fixedly installed with a pipe butt end 203 for connecting to the PE pipe body 1 at one end away from each other; the length of the butt joint is adjusted by the extension and contraction of the two telescopic sleeves and the telescopic tube. This method is not only convenient for users to operate, but also convenient for connecting the pipe butt end with the two PE pipe bodies, thereby achieving the advantages of convenient operation and easy docking of PE pipes, and solving the problem of fixed length of the connector and poor applicability.

[0039] The two telescopic sleeves 201 are slidably connected to the left and right ends of the telescopic tube 202, and the outer surfaces of the telescopic tube 202 are fixedly mounted with guide blocks that are slidably connected to the inner sides of the two telescopic sleeves 201. These not only provide guidance but also limit the movement of the two telescopic sleeves 201, ensuring stable sliding of the two telescopic sleeves 201 and improving the toughness of the joint 2.

[0040] It should be noted that the PE pipe body 1 is provided with a ceramic lining, a vacuum layer, a corrosion-resistant layer, a PE main layer, and a PE pipe inner wall layer. The PE main layer and PE pipe inner wall layer are respectively arranged on the outer and inner sides of the pipe. The vacuum layer is also provided with reinforcement blocks. The reinforcement blocks are elastic, allowing the vacuum layer 8 to maintain its existing shape when extended, providing a stable sound-isolating environment. When the city's water flows out of the PE pipe body, it first passes through the relatively soft PE pipe inner wall. The ceramic lining layer effectively isolates harmful chemicals but cannot prevent the transmission of sound. The sound of flowing water passes through the vacuum layer, which has no sound-transmitting medium and can theoretically completely isolate sound. The reinforcement blocks are relatively soft, thus ensuring the normal operation of the vacuum layer during the PE pipe laying process. The two ceramic lining layers can isolate the soil from microbial corrosion, ensuring the integrity and safety of the PE pipe body 1. The PE pipe inner wall layer is made of high-pressure polyethylene, which has a low density and is the softest material, which to a certain extent increases the flexibility of the PE pipe.

[0041] To achieve the fixation of the joint 2, please refer to Figures 1 to 3In this embodiment, a positioning structure 3 is provided on the outside of the joint 2; the positioning structure 3 includes a mounting plate 301 detachably mounted on the outer surfaces of the two telescopic sleeves 201, connecting ears 302 welded and mounted on the upper surfaces of the two mounting plates 301, a screw 303 passing through the two connecting ears 302, and a locking nut 304 threadedly mounted on the outside of the screw 303. The length of the butt joint 2 is adjusted by extending and retracting the two telescopic sleeves 201 and the telescopic tube 202. This method is not only convenient for the user to operate, but also convenient for connecting the pipe butt end 203 with the two PE pipe bodies 1, thereby achieving the advantages of convenient operation and facilitating the butt joint of PE pipes, and solving the problem of fixed length of the connector and poor applicability. At the same time, the locking nut 304 is fixed by the threaded cooperation with the screw rod 303 to ensure the connection effect of the butt joint 2 and the PE pipe body 1, and improve the connection stability of the butt joint 2 and the PE pipe body 1. After the butt joint 2 is fixed, by pressing the two pressing rods 405 to make the first offset hole 407 correspond to the second offset hole 408, the locking shell 404 can be moved and the elastic rope 403 can be pulled to lock the end of the shielding sleeve 401. Then, the pressing rod 405 is loosened, the first offset hole 407 is offset from the second offset hole 408, and the locking shell 404 is fixed to achieve sealing of the butt joint 2, ensuring that the butt joint 2 can be stably retracted.

[0042] It should be noted that the mounting plate 301 has an arcuate shape, which facilitates contact with the outer surface of the telescopic sleeve 201. The mounting plate 301 and the telescopic sleeve 201 are fixed together by bolts. Four locking nuts 304 are symmetrically arranged in groups of two on either side of the two connecting ears 302 to secure the butt joint 2. The exterior of the telescopic sleeve 201 is provided with several mounting holes, which, using bolts, allow for easy assembly and disassembly of the positioning structure 3, facilitating subsequent maintenance and position adjustment.

[0043] To improve the use of connector 2, please refer to Figure 1 、 Figures 4 to 6 In this embodiment, a protective structure 4 is installed between the two telescopic sleeves 201. The protective structure 4 includes a shielding sleeve 401 that is installed between the two telescopic sleeves 201, a locking shell 404 disposed on the outside of the shielding sleeve 401, and an elastic cord 403 that is installed inside the shielding sleeve 401. The elastic cord 403 has two ends that are inserted into the interior of the locking shell 404. Two opposing pressing rods 405 are slidably mounted within the locking shell 404, and a return spring 406 is fixedly mounted between the two pressing rods 405. Two first offset holes 407 are defined within the locking shell 404, and two second offset holes 408 are defined within the two pressing rods 405. The two first offset holes 407 and the two second offset holes 408 are correspondingly disposed.

[0044] Specifically, the shielding cover 401 has a mounting slot 402 with two connected ends. The elastic cord 403 is located within the mounting slot 402, with both ends extending through the mounting slot 402 and outside the shielding cover 401, thereby tightening the end of the shielding cover 401. The deformation of the return spring 406 moves the pressing rod 405, connecting or staggering the first offset hole 407 and the second offset hole 408, thereby locking and securing the elastic cord 403.

[0045] It can be understood that the two ends of the elastic rope 403 pass through the interior of the locking shell 404 and the two pressing rods 405 through two first offset holes 407 and two second offset holes 408, and the first offset hole 407 and the second offset hole 408 utilize the deformation of the reset spring 406 to move the pressing rod 405, so that the first offset hole 407 and the second offset hole 408 are connected or staggered, thereby realizing the locking and fixation of the elastic rope 403.

[0046] In this embodiment, two limiting plates 409 are symmetrically mounted inside the locking housing 404, and the two pressing rods 405 extend through the two limiting plates 409. The installation of the limiting plates 409 can limit the pressing rods 405, allowing them to move stably, improving the compression of the return spring 406, and at the same time improving the fixation of the elastic cord 403.

[0047] The working principle of the above embodiment is:

[0048] During use, the length of the joint 2 is adjusted by the extension and contraction of the two telescopic sleeves 201 and the telescopic tube 202, which facilitates the connection between the pipe docking end 203 and the two PE pipe bodies 1. After the joint 2 is fixed and docked, the locking nut 304 is used to cooperate with the thread of the screw rod 303 to fix it, so as to ensure the connection effect between the joint 2 and the PE pipe body 1. Then, by pressing the two pressing rods 405, the first offset hole 407 and the second offset hole 408 are aligned, the locking shell 404 can be moved and the elastic rope 403 can be pulled to lock the end of the shielding sleeve 401. Finally, the pressing rod 405 is loosened, the first offset hole 407 and the second offset hole 408 are offset, and the locking shell 404 can be fixed to achieve the sealing of the joint 2, so as to ensure that the joint 2 can be stably contracted.
