[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0026] As shown in Figures 1 to 8 Figure 1, the present application provides a pipeline assembly, which comprises N pipe bodies 10, the first ends of the N pipe bodies 10 are connected with N pipe joints 20, the N pipe joints 20 are arranged at intervals along a first direction, the parts of the N pipe bodies 10 close to the N pipe joints 20 are arranged at intervals along the first direction, and the N pipe bodies 10 gradually bend in a direction away from the N pipe joints 20, so that the arrangement direction of the N pipe bodies 10 changes from the first direction to a second direction, the first direction and the second direction are not parallel, and N is an integer greater than 1.

[0027] In the present embodiment, the two ends of the pipe joint 20 can be connected with the pipe body 10 respectively, one end of one pipe joint 20 is connected with one pipe body 10, the N pipe bodies 10 are arranged at intervals along the first direction on the same side of the N pipe joints 20 and extend in a direction away from the N pipe joints 20, and the N pipe bodies 10 gradually bend in the extending process, so that the arrangement direction of the N pipe bodies 10 changes from the first direction to the second direction. In this way, the adjacent pipe bodies among the bent N pipe bodies 10 can be limited to each other, so as to offset the internal stress generated in the assembling process of the pipe body 10, reduce the situation that the pipe body 10 is twisted off from the pipe joint 20, and thus improve the sealing effect of the pipe joint 20.

[0028] It should be understood that, during the tightening process, the pipe body 10 and the pipe joint 20 will rotate as a whole due to the friction at the interface, and after reaching the required tightening torque, the pipe body 10 will retain a certain elastic deformation (i.e., internal stress) and always maintain the tendency to restore to its original state, which will cause the pipe body 10 to untwist from the pipe joint 20 over a long period of time and cause leakage.

[0029] Optionally, the first direction is perpendicular to the second direction.

[0030] In this embodiment, the N pipe bodies 10 are arranged on the same side of the N pipe joints 20 along the first direction, and after being twisted and bent, the N pipe bodies 10 are arranged along the second direction. The first direction is perpendicular to the second direction, in other words, the first plane on which the N pipe bodies 10 are located after being twisted and bent is perpendicular to the second plane on which the N pipe bodies 10 are located before being bent. By fixing the N pipe bodies 10 arranged along the second direction in the second plane, the untwisting of the pipe body 10 from the pipe joint 20 is reduced.

[0031] Compared with the prior art, the pipe assembly provided by the present application can relieve the deformation of the pipe body 10 during assembly and improve the sealing effect of the pipe joint 20.

[0032] Optionally, it further comprises an isolation pipe clamp, the isolation pipe clamp comprises at least N clamping holes, and the bent segments of the N pipe bodies are clamped one by one with the N clamping holes so that the bent segments of the N pipe bodies 10 are fixed in a manner of being arranged along the second direction.

The three-hole isolation pipe clamp 301 comprises 3 clamping holes, and the two-hole isolation pipe clamp 302 comprises 2 clamping holes. The three-hole isolation pipe clamp 301 and the two-hole isolation pipe clamp 302 are respectively used to fix the corresponding bent segments of the 2 pipe bodies 10 in a manner of being arranged along the second direction. The 2 pipe bodies 10 after being bent can be limited by the isolation pipe clamp to offset the internal stress generated during assembly of the pipe body 10, reduce the untwisting of the pipe body 10 from the pipe joint 20, and improve the sealing effect of the pipe joint 20.

[0034] The three-hole isolation pipe clamp 301 is arranged at the position of the bending section close to the pipe joint 20, one pipe body 10 is fixed by one bayonet, and the part of the three-hole isolation pipe clamp 301 not fixing the pipe body 10 is used to abut against the assembly surface, so as to reduce the gap between the pipe body 10 and the assembly surface, further limit the position, form an anti-rotation structure through the three-hole isolation pipe clamp 301, avoid the pipe body 10 from rotating during assembly, and prevent the pipe body 10 from rotating back and untwisting; the two-hole isolation pipe clamp 302 can be arranged at the extension area of the bending section, in the case that the pipe body 10 is long, the gap between the plurality of pipe bodies 10 is reduced, so as to improve the connection stability of the pipe body 10 and the pipe joint 20, and further improve the sealing effect of the pipe joint 20.

Moreover, the pipe body 10 is detachably connected with the female pipe joint through the male pipe joint 201, so that different lengths of pipe bodies 10 can be replaced according to actual assembly requirements.

[0038] Optionally, a first fixing frame 40 is further included, the first fixing frame 40 comprises a first fixing part 401 and a supporting part 402, the first fixing part 401 is arranged at a target assembly surface, the supporting part 402 is used to fix the female pipe joint, and the supporting part 402 extends towards the direction away from the target assembly surface, so that the female pipe joint is arranged at intervals with the target assembly surface.
