In order to limit the movement of the pipe body sealing ring 8 and limit the insertion of the environmentally friendly PE pipe body 1 and the pipe body connecting ring 6, the middle part of the pipe body connecting ring 6 is fixedly connected with a pipe body limiting ring 7, and the end of the pipe body sealing ring 8 is attached to the side surface of the pipe body limiting ring 7.

[0056] Further, the end connecting piece 2 further comprises two connecting reinforcing plates 10, the two connecting reinforcing plates 10 are symmetrically arranged, the two connecting reinforcing plates 10 are buckled on the outer side of the end of the environmentally friendly PE pipe body 1, the two connecting reinforcing plates 10 correspond to the position of the pipe body connecting ring 6, the inner side of the connecting reinforcing plate 10 is fixedly connected with a limiting plug 11, the limiting plug 11 is inserted into the limiting slot 5, and the ends of the two connecting reinforcing plates 10 are detachably fixedly connected. In order to facilitate the connection or disassembly of the two connecting reinforcing plates 10, the end of the connecting reinforcing plate 10 is fixedly connected with a fixing lug 12, and the fixing lug 12 at the end of the two connecting reinforcing plates 10 is detachably fixed by a fixing screw 13. In order to avoid accidental falling of the pipe body sealing ring 8 before use of the end connecting piece 2, the outer side of the pipe body sealing ring 8 is provided with a sealing ring anti-falling groove 9, and the limiting plug 11 on the inner side of the connecting reinforcing plate 10 is inserted into the sealing ring anti-falling groove 9.

[0057] Through the structural design of the end connecting piece 2, the device can realize the connection and fixation effect between the ends of the plurality of environmentally friendly PE pipe bodies 1, realize the series connection between the plurality of environmentally friendly PE pipe bodies 1, and the overall structure is relatively simple, without the need of using other hot melting equipment, thereby reducing the cost of connection between the pipes, and the device can be quickly disassembled when needed.

[0058] The parallel fixing piece 3 is used for connecting between two adjacent environment-friendly PE pipe bodies 1. Specifically, the parallel fixing piece 3 comprises a combined buckle 14, pipe body buckle grooves 15 are formed on both sides of the interior of the combined buckle 14, a matching block 17 is vertically inserted and connected at the middle upper end of the combined buckle 14, and the matching block 17 is detachably fixedly connected with the combined buckle 14 through a fixing bolt 21.

[0059] It can be known that when connecting between the end portions of a plurality of environment-friendly PE pipe bodies 1, the end portions of two environment-friendly PE pipe bodies 1 to be connected are respectively sleeved at the positions of the two ends of the pipe body connecting ring 6 through the connecting slot 4, and the end portions of the environment-friendly PE pipe bodies 1 are attached to the side surface of the pipe body limiting ring 7, the gap between the pipe body connecting ring 6 and the connecting slot 4 is sealed to achieve a sealing effect by the pipe body sealing ring 8, after the two environment-friendly PE pipe bodies 1 are connected with the pipe body connecting ring 6, the two connecting reinforcing plates 10 are buckled at the connecting positions of the two environment-friendly PE pipe bodies 1, and the limiting plug-in block 11 on the inner side of the connecting reinforcing plate 10 extends into the interior of the sealing ring anti-disengagement groove 9 through the limiting through slot 5, and the end portions of the two connecting reinforcing plates 10 are fixed by the fixing screw 13, so as to complete the connection between the two environment-friendly PE pipe bodies 1, and in this way, the connection between a plurality of environment-friendly PE pipe bodies 1 can be achieved.

[0060] When two adjacent environment-friendly PE pipe bodies 1 need to be fixed, the end portions of the two environment-friendly PE pipe bodies 1 to be fixed are placed in the two pipe body buckle grooves 15 on the inner side of the combined buckle 14, the combined buckle 14 is used to limit the left and right of the two environment-friendly PE pipe bodies 1, the matching block 17 is inserted into the upper end of the combined buckle 14 and located between the two environment-friendly PE pipe bodies 1, and the matching block 17 and the combined buckle 14 are fixed by the fixing bolt 21, so as to limit the upper and lower of the two environment-friendly PE pipe bodies 1, and then the fixation between the two environment-friendly PE pipe bodies 1 is completed.

[0062] Embodiment 2:

[0063] The environment-friendly PE pipe provided in Embodiment 1 is further optimized, and specifically, as shown in Figure 6 The first protruding portion 16 is arranged at the middle of the inner side of the combined buckle 14, the second protruding portion 18 is arranged at the middle of the lower end of the matching block 17, and the positions of the first protruding portion 16 and the second protruding portion 18 correspond to each other.

[0064] The end of the fitting block 17 is fixedly connected with a connecting plug 19, the upper end of the combined buckle 14 near the end of the fitting block 17 is provided with a plug slot 20, and the end of the fitting block 17 is vertically plug-connected with the plug slot 20 at the same end through the connecting plug 19.

[0065] Through the above structural design, the further limiting of the two environmentally friendly PE pipe bodies 1 inside the combined buckle 14 can be realized through the cooperation of the combined buckle 14 and the second protruding part 18, and the sliding phenomenon of the two environmentally friendly PE pipe bodies 1 inside the combined buckle 14 is avoided. The plug connection of the connecting plug 19 at the end of the fitting block 17 and the plug slot 20 at the upper end of the combined buckle 14 is performed, so that after the fitting block 17 is fixed with the combined buckle 14, the end of the fitting block 17 is connected with the end of the combined buckle 14, thereby reducing the bending deformation of the two ends of the combined buckle 14.

[0066] Embodiment 3:

[0067] The environmentally friendly PE pipe provided in Embodiment 1 is further optimized, and specifically, as shown in Figure 6 The combined buckle 14 and the first protruding part 16 are integrally formed, the fitting block 17, the second protruding part 18, and the connecting plug 19 are integrally formed, and the materials of the combined buckle 14 and the second protruding part 18 are plastic, which is easy for the production of the side-by-side fixing piece 3.

[0068] Embodiment 4:

[0069] The environmentally friendly PE pipe provided in Embodiment 1 is further optimized, and specifically, as shown in Figures 4-5 The connecting reinforcing plate 10, the limiting plug 11, and the fixing ear 12 are integrally formed, which can effectively improve the connection strength between the connecting reinforcing plate 10, the limiting plug 11, and the fixing ear 12. The materials of the connecting reinforcing plate 10, the limiting plug 11, and the fixing ear 12 are plastic, which is easy for the production of the end connecting piece 2.

[0070] Embodiment 5:

[0071] The environmentally friendly PE pipe provided in Embodiment 1 is further optimized, and specifically, as shown in Figure 8 The environmentally friendly PE pipe body 1 can be any one of a PE straight pipe, a PE elbow pipe, a T-shaped PE pipe, and a cross-shaped PE pipe.

[0072] The optimized environmentally friendly PE pipe body 1 is no longer limited to a single specification in form, but is innovatively designed into multiple structural forms, including but not limited to a PE straight pipe, a PE elbow pipe, a T-shaped PE pipe, and a cross-shaped PE pipe. These pipe bodies of different forms can flexibly cope with various complex pipe layout requirements, greatly broadening the application scenarios of the product.

[0073] In the structural design, we fully consider the connection and fixation of different forms of PE pipe body. First, for all forms of environmental protection type PE pipe body 1, a standardized end connector 2 is designed at the end thereof. These end connectors 2 are not only structurally strong and easy to operate, but also have good universality, which can ensure the quick and reliable end connection between PE straight pipes, PE elbow pipes, T-shaped PE pipes and cross-shaped PE pipes, thereby building a stable and efficient pipeline system.

[0074] In addition, in order to further improve the overall stability and space utilization of the pipeline system, we have specially designed side-by-side fixing pieces 3 for PE straight pipes, PE elbow pipes and T-shaped PE pipes. These side-by-side fixing pieces 3 are made of high-strength materials, compact structure, easy to install, can effectively fix multiple PE pipes of the same type or different types side by side, forming a neat and uniform pipeline arrangement, which is not only beautiful but also practical.

[0075] On the basis of the above embodiment, clamping rings are arranged on both sides of the outer ring of the pipe body connecting ring 6, and the pipe body sealing ring 8 is arranged between the two clamping rings. The clamping ring and the pipe body limiting ring 7 are used to limit the axial position of the pipe body sealing ring 8 in the pipe body connecting ring 6, preventing the pipe body sealing ring 8 from separating from the pipe body connecting ring 6. Since the clamping ring structure will cause the structure in the entire drawing to be too cluttered, the clamping ring structure is not shown in the drawing;

[0076] As shown in Figures 9-13 The annular cavity 22 is arranged in the pipe body sealing ring 8, and the annular cavity 22 is located on the side of the sealing ring anti-separation groove 9 close to the end of the pipe body connecting ring 6. The inner side wall of the annular cavity 22 is respectively provided with a first sliding ring 23 and a second sliding ring 24. The first sliding ring 23 and the second sliding ring 24 are fixedly connected with the inner side wall of the annular cavity 22, which can be adhesion or embedding the sliding ring into the inner side wall of the annular cavity 22;

[0077] In addition, the annular cavity 22 is provided with a tension ring 25, and the cross section of the tension ring 25 is a wedge structure. The end of the tension ring 25 with small thickness is arranged close to the end of the pipe body connecting ring 6. The tension ring 25 is inserted into the annular cavity 22, and the first sliding ring 23 and the second sliding ring 24 are respectively located on the inner and outer sides of the tension ring 25. The tension ring 25 is in sliding cooperation with the first sliding ring 23 and the second sliding ring 24. In order to facilitate the installation of the tension ring 25, a ring-shaped opening 26 is arranged on the inner side or the outer side of the pipe body sealing ring 8 corresponding to the annular cavity 22. The tension ring 25 is placed into the annular cavity 22 through the ring-shaped opening 26;

[0078] Further, the wedge block 27 is arranged at the position corresponding to the sealing ring anti-falling groove 9 of the tension ring 25, the wedge block 27 has no connection relationship with the tension ring 25, of course, it can be understood that the wedge block 27 has the same arc as the pipe body connecting ring 6, the side surface of the limiting plug 11 is provided with a wedge chamfer 28, with the pipe body connecting ring 6 being tightly held by the connecting reinforcing plate 10, the wedge chamfer 28 on the limiting plug 11 moves relative to the wedge block 27, with the radial movement of the limiting plug 11, the axial movement of the tension ring 25 is pushed, and then the first sliding ring 23 and the second sliding ring 24 are pushed to move outward, after the tension ring 25 is installed into the annular cavity 22, the pipe body sealing ring 8 is sleeved on the environment-friendly PE pipe body 1, and the alignment is completed, then the wedge block 27 is installed in the sealing ring anti-falling groove 9, the wedge block 27 can be directly placed in the sealing ring anti-falling groove 9; or the wedge block 27 is placed in the sealing ring anti-falling groove 9, and then the wedge block 27 is bonded to the side surface of the tension ring 25, the whole structure is more reasonable in installation.

[0079] Since the pipe body sealing ring 8 has a certain width of annular structure, when the environment-friendly PE pipe body 1 is sleeved, if the thickness of the pipe body sealing ring 8 is designed to be too thick, the environment-friendly PE pipe body 1 cannot be smoothly sleeved into the combined structure of the pipe body sealing ring 8 and the pipe body connecting ring 6, so the thickness of the pipe body sealing ring 8 needs to be designed to be appropriately thin, which finally leads to the poor sealing effect of the pipe body sealing ring 8. Therefore, by arranging the tension ring 25 in the annular cavity 22, the axial movement of the tension ring 25 is pushed by the radial movement of the limiting plug 11, and the first sliding ring 23 and the second sliding ring 24 are pushed to move outward by the tension ring 25, so that the pipe body sealing ring 8 is expanded outward by the tension ring 25, the pipe body connecting ring 6 and the sidewall of the environment-friendly PE pipe body 1 are tightly contacted by the pipe body sealing ring 8, and the problem of poor sealing effect between the pipe body sealing ring 8 and the pipe body connecting ring 6 and the environment-friendly PE pipe body 1 can be overcome.

[0080] Through the above optimization design, not only the form selection of the environment-friendly PE pipe body 1 is enriched, but also the flexibility and reliability of the connection and fixation are significantly improved. Whether it is straight laying, curved connection or branch expansion, the optimized environment-friendly PE pipe body 1 can easily cope with it, and provides a more comprehensive and efficient solution for various pipeline projects.
