[0024] The technical solution of an embodiment of the present application will be described in detail below with reference to the accompanying drawings, but the protection scope of the present application is not limited to the described embodiment.

[0025] Embodiment: A multi-overlapping pipe fixing device, comprising a hoop 10, a connecting piece 20, a connecting rod 30 and a sleeve 40.

[0026] The hoop 10 is a hoop with adjustable ring diameter, used for being sleeved on the outside of a large-diameter pipe to fix the large-diameter pipe. The two ends of the hoop 10 are staggered and each is provided with a first through hole 11. A first bolt 12 is arranged on the first through hole 11. The ring diameter of the hoop 10 is adjusted by adjusting the overlapping rate of the two ends of the hoop 10 and fixed by the first bolt 12, so as to adapt to pipes with different diameters and widen the application range of the fixing device.

[0027] One end of the connecting piece 20 is fixedly connected to the hoop 10, and the distance between the connecting point and one end of the hoop 10 is 1 / 4-1 / 2 of the length of the hoop 10, so as to facilitate the adjustment of the ring diameter of the hoop 10 and the screwing of the first bolt 11. The other end of the connecting piece 20 is hingedly connected to the connecting rod 30. The connecting rod 30 can rotate 180° around the hinge on one side of the plane where the hoop 20 is located, so that the fixing device is easy to install and dismount from the pipe.

[0028] The sleeve 40 is arranged at the end of the connecting rod 30 away from the connecting piece 30, comprising a first clamping piece 41 fixedly connected to one end of the connecting rod 30 and a second clamping piece 42 detachably connected to the first clamping piece 41. The first clamping piece 41 is a straight rod perpendicular to the connecting rod 30, and the second clamping piece 42 is an inverted L-shaped rod. One side of the second clamping piece 42 is parallel to the first clamping piece 41. In the use process of the fixing device, the first clamping piece 41 abuts against the edge of the pipe, and the second clamping piece 42 clamps the sidewall of all the pipes, so that the small-diameter pipes cannot slide towards the second clamping piece 42 and fall off from the large-diameter pipe.

[0029] More specifically, the parallel edges of the second clamping member 42 and the first clamping member 41 are provided with second through holes 43, and the second through holes 43 are provided with second bolts 44. By adjusting the coincidence rate of the parallel edges of the second clamping member 42 and the first clamping member 41 and the first clamping member 41 and fixing by the second bolts 44, the range of the total wall thickness of the pipe that can be clamped by the fixing device is wider, so as to widen the application range of the fixing device.

[0030] When the present application is used, the hoop 10 is sleeved on the large-diameter pipe at a suitable position and clamped, the connecting rod 30 is rotated towards the large-diameter pipe to make the first clamping member 41 abut against the edge of the pipe, the second clamping member 42 is moved to just clamp all the side walls of the pipe, and then the second bolt 44 is used for fixing, so that the small-diameter pipe cannot slide towards the second clamping member 42 and is prevented from falling off from the large-diameter pipe. One fixing device is arranged at each end of the pipe, so as to fix the small-diameter pipe in the large-diameter pipe and effectively prevent the small-diameter pipe from falling off from the large-diameter pipe and bruising the workers. The hoop 10 is a ring-shaped hoop with adjustable ring diameter, which can adapt to pipes with different diameters. The distance between the second clamping member 42 and the connecting rod 30 can be adjusted, which can adapt to different total wall thicknesses of the pipes, so as to widen the application range of the fixing device. The fixing device has simple structure, is convenient to assemble and disassemble, and has high practicability.

[0031] The above is the preferred embodiment of the present application. It should be noted that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered as the protection scope of the present application.
