[0009] As a further description of the above technical solution:

[0010] The buckle is a polyethylene buckle.

[0011] As a further description of the above technical solution:

[0012] The surface of the second connecting pipe is threadedly connected with a fixing pipe, and the top end of the fixing pipe is rotatably connected with a fixing plate, and a fixing groove with an inverted truncated cone cross section is provided inside the fixing plate.

[0013] As a further description of the above technical solution:

[0014] A ball in contact with the inner wall of the fixing groove is arranged on one side of the connecting rod.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3, a heat preservation pipe connection structure for a water meter box, comprising a first connection pipe 1 and a second connection pipe 2, on which connection components are installed; the interior of the connection component comprises a through groove 3 symmetrically arranged on the surface of the first connection pipe 1, and an arc-shaped buckle 4 is arranged on the top of the inner side of the through groove 3, and a baffle 5 is arranged on the bottom end of the buckle 4; the interior of the connection component also comprises a connecting rod 6 arranged equidistantly on the surface of the second connection pipe 2 in an annular manner, and one end of the connecting rod 6 passes through the second connection pipe 2 and is connected to a limiting plate 7, and a spring 8 is connected between the limiting plate 7 and the inner wall of the second connection pipe 2. When in use, the first connection pipe 1 is first passed through a through hole (not shown) on the water meter box. Of course, the inner diameter of the through hole should be smaller than the distance between the two buckles 4. The first connection pipe 1 can be limited to the surface of the through hole of the water meter box by the buckle 4. The insulation pipe is passed through the second connecting pipe 2 and the first connecting pipe 1 to connect the water meter inside the water meter box. After the connection is completed, limit the fixing plate 10 with one hand and rotate the fixing pipe 9, so that the fixing pipe 9 can rotate and drive the fixing plate 10 to move. The ball on the connecting rod 6 can be squeezed through the fixing groove inside the fixing plate 10, so that the ball, the connecting rod 6 and the limiting plate 7 can be limited and moved, so that the insulation pipe can be clamped and limited by the limiting plate 7, and the insulation pipe and the water meter box can be connected. Of course, the above-mentioned operation method is not the only one, and it needs to be used according to actual usage. The surface of the second connecting pipe 2 is annularly provided with a through hole, and the inner diameter of the through hole is the same as the diameter of the connecting rod 6, so that when the connecting rod 6 is squeezed, it can drive the limiting plate 7 to move through the through hole. Figure 1 As shown, the interior of the first connecting pipe 1 is connected to the surface of the insulation pipe, and the surface of the second connecting pipe 2 is connected to the water inlet and outlet holes on the water meter box.

[0024] Furthermore, the buckle 4 is a polyethylene buckle 4. Polyethylene is a common plastic material with good toughness and wear resistance.

[0025] Furthermore, a fixing tube 9 is threadedly connected to the surface of the second connecting tube 2, and a fixing plate 10 is rotatably connected to the top end of the fixing tube 9. A fixing groove with an inverted truncated cone cross section is provided inside the fixing plate 10. The fixing tube 9 is rotated to drive the fixing plate 10 rotatably connected to the top end thereof to move, so that the connecting rod 6 and the like can be squeezed through the inverted truncated cone-shaped fixing groove provided inside the fixing plate 10 to move it.

[0026] Furthermore, a ball in contact with the inner wall of the fixed groove is provided on one side of the connecting rod 6, and the ball facilitates the fixed groove to move on its surface, so that the ball, the connecting rod 6 and the limit plate 7 can be squeezed to move through the fixed groove, so as to clamp and limit the insulation pipe through the limit plate 7.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
