[0027] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention. Example

[0028] Please refer to Figure 1 This embodiment provides a pipe assembly 010, which includes a plurality of pipes, and two adjacent pipes are connected to form a component through a corresponding connection structure 10. This embodiment takes a rectangular pipe as an example for description, and in other embodiments, the connection structure 10 can also be used for a circular pipe or other pipes.

[0029] For ease of description, two adjacent pipes are named as the first pipe 011 and the second pipe 012. The ends of the two pipes are butted against each other, and four connecting structures 10 are arranged at the butting positions; the four connecting structures 10 are respectively located on the four sides of the rectangular pipe. Connecting parts are arranged on the four sides of the pipes, which are used to connect with the corresponding connecting structures 10.

[0030] Please refer to Figure 1 and Figure 2 The connection structure 10 includes a nut 11, a fastening bolt 12 and two connecting rods 13. One end of the two connecting rods 13 is respectively connected to the connecting parts of the two pipes, and the fastening bolt 12 and the nut 11 connect the other ends of the two connecting rods 13. When the nut 11 is tightened, the fastening bolt 12 can apply tension to the two connecting rods 13, thereby making the ends of the two adjacent pipes fit tightly.

[0031] Specifically, the connecting rod 13 includes a rod body 133 and a connecting end 131 and a fastening end 132 located at both ends of the rod body 133. The connecting end 131 of the connecting rod 13 is connected to the corresponding pipe (with Figure 4 For example, the left connecting rod corresponds to the left pipe, and the right connecting rod corresponds to the right pipe), the rod body 133 of the connecting rod 13 extends along the length direction of the pipe to the connection of the two pipe ends, and the fastening end 132 is located at the above connection. The fastening end 132 is connected to the rod body 133 in an L-shape, and the side of the fastening end 132 close to the connecting end 131 is a wedge-shaped surface, which is inclined toward the outer wall direction of the corresponding pipe, that is, inclined inward; so that the wedge-shaped surface is set at an acute angle with the outer surface of the corresponding pipe.

[0032] Please refer to Figure 4 and Figure 5 , the fastening bolt 12 includes a fastening head 121 and a threaded rod 122, and the fastening head 121 is arranged at one end of the threaded rod 122. Along the axial section of the threaded rod 122, the cross-section of the fastening head 121 is an isosceles trapezoidal structure, and the width of the end close to the threaded rod 122 is smaller; the above design makes the fastening head 121 include two wedge-shaped surfaces. After the assembly is completed, the wedge-shaped surfaces of the two connecting rods 13 respectively cooperate with the two wedge-shaped surfaces of the fastening head 121, and the fastening end 132 and the connecting end 131 of the same connecting rod 13 are respectively located on both sides of the fastening head 121; at this time, the threaded rod 122 of the fastening bolt 12 extends in a direction away from the outer surface of the waveguide tube, and the fastening head 121 is close to the outer surface of the pipe. The nut 11 is sleeved on the threaded rod 122, and the nut 11 and the fastening head 121 are respectively located on both sides of the wedge-shaped surface of the fastening end 132; when the nut 11 is tightened, the two wedge-shaped surfaces of the fastening head 121 and the wedge-shaped surfaces of the corresponding connecting rods 13 are squeezed against each other, so that the two connecting rods 13 tend to approach each other, thereby making the end faces of the two pipes fit tightly.

[0033] Furthermore, the outer walls of the first pipe 011 and the second pipe 012 are both provided with a strip groove 013, which extends along the length direction of the corresponding pipe. One end of the strip groove 013 extends to the mating surface where the two pipes abut; the other end of the strip groove 013 is provided with a clamping groove 014, which is T-shaped with the strip groove 013. In this embodiment, the clamping groove 014 constitutes the connecting portion of the corresponding pipe. After the connecting rod 13 is assembled to the corresponding pipe, the rod body 133 of the connecting rod 13 is arranged in the strip groove 013, and the connecting end 131 of the connecting rod 13 is arranged in the clamping groove 014.

[0034] With the above structure, since the connecting rod 13 is completely set in the corresponding strip groove 013 and the clamping groove 014 of the pipeline, the connecting structure 10 does not occupy any space outside the pipeline. The overall structure of the pipeline assembly 010 is more compact and does not require much installation space.

[0035] In order to prevent the connecting rod 13 from falling off from the strip groove 013, a retaining edge 0131 is provided on one side of the strip groove 013 close to the outer surface of the corresponding pipe. After the retaining edge 0131 is provided, even if the pipe assembly 010 is subjected to relatively large vibration, it will not fall off from the strip groove 013, thereby making the pipe assembly 010 more reliable.

[0036] Alternatively, in other embodiments, the outer surface of the pipe may not be provided with the strip groove 013 and the clamping groove 014. In this case, a convex portion may be provided on the outer surface of the pipe as a connecting portion, the connecting rod 13 is attached to the outer surface of the pipe, and the connecting end 131 is connected to the connecting portion. Since the lateral dimension of the connecting rod 13 is small, the entire connecting structure 10 occupies less lateral space of the pipe; compared with the flange-type connecting structure 10, it can still save installation space.

[0037] It should be noted that, in other embodiments, the pipeline component 010 may also be provided with two connecting structures 10, in which case the two connecting structures 10 are respectively provided on two opposite sides; or, it may also be provided with only one connecting structure 10 on one side, in which case the other side of the adjacent pipelines is connected by a hinge structure.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
