[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] The pipeline is installed between the lower arc plate 4 and the upper arc plate 7. The pipeline is surrounded by the two lower arc plates 4 and the upper arc plate 7. The elastic connection device can be adjusted to clamp the pipeline with the lower arc plate 4 and the upper arc plate 7. The pipeline can be coated with an insulation layer as needed.

[0025] In this embodiment, the base 1 is provided with a limited slide groove 101, in which two guide rails 102 are fixedly installed in parallel, and the slide seat 2 is provided with a through hole, in which the guide rails 102 are slidably installed. The spacing of the lower arc plate 4 can be adjusted left and right to cooperate with the elastic connection device.

[0026] In this embodiment, a mounting plate 9 is fixedly mounted on the bottom side of the base 1, and two mounting holes 901 are provided on the mounting plate 9. Mounting bolts are arranged in the mounting holes 901. The base 1 can be fixed on a wall or a reinforced concrete base by mounting bolts.

[0027] In this embodiment, the elastic connecting device includes a stud 10, and through holes are provided on the first connecting plate 3, the second connecting plate 5, the third connecting plate 6 and the fourth connecting plate 8. The stud 10 is movably installed in the through holes, and two gaskets 11 are slidably installed on both sides of the stud 10, and a strong spring 12 is provided between the two gaskets 11 on the same side. Nuts 13 are threadedly connected at both ends of the stud 10, the outer gasket 11 is tightly against the nut 13, and the inner gasket 11 is tightly against the first connecting plate 3, the second connecting plate 5, the third connecting plate 6 or the fourth connecting plate 8.

[0028] When the pipeline expands due to heat, the lower arc plate 4 and the upper arc plate 7 are pushed outward, so that the two inner gaskets 11 move outward and the strong spring 12 is compressed; when the pipeline contracts due to cold, the strong spring 12 extends, pushing the two inner gaskets 11 closer to each other, so that the lower arc plate 4 and the upper arc plate 7 move inward and clamp the pipeline.
