[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1 , which discloses an assembled pipeline for communication pipeline construction according to an embodiment of the present invention. It includes a joint end 1. A plum blossom hole is formed inside the joint end 1. A plum blossom pipe is inserted and installed in the plum blossom hole. A connecting flange 2 is fixedly installed on the outer side of one end of the joint end 1. It further includes a turning unit 3. The turning unit 3 is a fan-shaped unit obtained by equally dividing a ring formed by connecting the plum blossom pipes end to end. Plugging rings 31 and plugging grooves 32 are respectively arranged at both ends of the turning unit 3. The plugging rings 31 and the plugging grooves 32 of adjacent turning units 3 are plugged and connected. There are two joint ends 1. Plugging rings 31 and plugging grooves 32 are respectively arranged at one ends of the two joint ends 1 close to the connecting flange 2. Connecting bolts 4 are arranged on the connecting flange 2. The connecting bolts 4 connect the two connecting flanges 2.

[0029] Specifically, the two joint ends 1 are used to connect the two plum blossom pipes. A plurality of turning units 3 are arranged between the two joint ends 1. The turning unit 3 is a fan-shaped unit obtained by equally dividing a ring formed by connecting the plum blossom pipes end to end. The positions required for different turning angles are adapted by plugging a plurality of turning units 3, and are fastened by the connecting bolts 4.

[0030] In this way, a turning angle is formed by assembling a plurality of turning units 3, and the plum blossom pipes of the communication pipeline are fixed and connected by the joint ends 1 and the connecting bolts 4, so that the plum blossom pipes of the communication pipeline can be turned during laying and assembly, which is convenient for the laying of the communication pipeline.

[0031] In some feasible ways, the turning unit 3 is a fan-shaped unit obtained by equally dividing a ring formed by connecting the plum blossom pipes end to end. That is, each turning unit 3 can deflect the two joint ends 1 by a unit angle. By calculating the required turning angle, the number of required turning units 3 is determined for assembly. It should be understood that the turning unit 3 is a part of the ring formed by connecting the plum blossom pipes end to end, and the turning radius is a fixed value. When different turning radii are required, different turning units 3 are needed.

[0032] As a specific implementation manner of an assembled pipeline for communication pipeline construction provided by the application, please refer to Figure 1 And Figure 2 , the connecting bolt 4 includes two stud ends 41. A steel cable 42 is installed between the two stud ends 41. The stud ends 41 are threadedly connected with fastening nuts 43.

[0033] Generally speaking, multiple turning units 3 are assembled to form a turn. The end faces of the two connecting flanges 2 are not parallel. By setting the steel cable 42 as a flexible connection, the steel cable 42 can adapt to the bending of the turning unit 3, and thus better fix the turning unit 3.

[0034] Furthermore, the stud end 41 is a hollow tubular shape. The steel cable 42 is inserted and connected to the stud end 41. A plurality of fastening grooves 411 are circumferentially arrayed at one end of the stud end 41 close to the steel cable 42. The inner hole of the stud end 41 is frustum-shaped, and the end where the fastening grooves 411 are located is the small-diameter end.

[0035] It should be understood that the turning units 3 are assembled according to different turning angles. For different numbers of assembled units, the required lengths of the steel cables 42 are also different. By setting the hollow tube to be inserted and connected with the steel cable 42, the length of the steel cable 42 can be adjusted. After the adjustment is completed, by screwing the fastening nut 43 to the position of the fastening groove 411, the inner diameter of the part of the fastening groove 411 is smaller. When the fastening nut 43 is screwed tightly, the side wall of the stud end 41 presses the steel cable 42 inward to complete the fixation.

[0036] In some feasible ways, for the convenience of installing the steel cable 42, in the initial state, the outer part of the stud end 41 at the position of the fastening groove 411 expands, so that the diameter of the small-diameter end of the frustum-shaped hole is not less than the diameter of the steel cable 42.

[0037] As another specific implementation manner of the assembled pipeline for communication pipeline construction provided by the application, the connection holes of the connecting flange 2 are arranged at the concave seams on the outer side of the corrugated pipe.

[0038] It should be understood that the corrugated pipe is formed by circumferentially arraying 6 pipe fittings. There are V-shaped groove-like concave seams at the intersections of the pipe fittings. By arranging the connection holes at the concave seams on the outer side of the corrugated pipe, through the structure at the intersection position, the supporting strength of the pipe fittings for the fastening force of the connecting bolts 4 is improved.

[0039] As a specific implementation manner of the assembled pipeline for communication pipeline construction provided by the application, please refer to Figure 1 , the turning unit 3 includes a housing part 301, and an inner core part 302 is inserted and installed inside the housing part 301.

[0040] It should be understood that the corrugated pipe is mostly made of materials such as PVC. The turning unit 3 is usually made by processes such as injection molding. There are grids inside the turning unit 3 for adapting to the corrugated pipe. By separately setting the housing part 301 and the inner core part 302, the housing and the grid are made separately, reducing the difficulty of the manufacturing process.

[0041] Furthermore, a limiting plate is fixedly arranged inside the housing part 301. When the inner core part 302 is inserted, one end far from the limiting plate protrudes from the housing part 301 to form a plugging ring 31, and one end of the limiting plate far from the inner core part 302 forms a plugging groove 32.

[0042] It should be understood that when the inner core part 302 is inserted, it is misaligned with the outer shell part 301, and the insertion rings 31 and the insertion grooves 32 are formed at both ends of the outer shell part 301. The position where the inner core part 302 is inserted is restricted by the limiting plate, which is convenient for forming the insertion rings 31 and the insertion grooves 32, further reducing the difficulty of the manufacturing process and facilitating the manufacturing.

[0043] In some feasible ways, the joint end 1 is provided with a limiting plate. The insertion ring 31 of the joint end 1 is formed by inserting the inner core part 302. The limiting plate can be set as an annular protrusion adapted to the shapes of the outer shell part 301 and the inner core part 302, or positioning holes can be provided in the outer shell part 301 and the inner core part 302, and the limiting plate is set as a positioning pin.

[0044] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
