In the installation process of some large pipelines, it is necessary to fix the bent plate part according to the actual situation to ensure the long-term connectivity of the pipeline, so pipeline fixing equipment is needed.

[0003] When the traditional pipe fixing device is in use, the traditional pipe fixing device is fixed by passing the bent pipe through the inner cavity of the fixing device, and then adjusting the distance between the upper and lower fixing plates by turning the screw. This method cannot pass the bent pipe between the fixing plates well when the pipe is very long, which is inconvenient. In addition, when fixing, it is fixed by turning the screw, and it is troublesome to turn the screw frequently. Utility Model Content

[0009] As a preferred technical solution of the utility model: the installation position of the rotating shaft does not coincide with the center position of the cam, and the rotating shaft is installed at a position offset to one side of the center of the cam.

[0010] As a preferred technical solution of the utility model: a rubber anti-skid pad is installed on the outer wall of the upper fixing platform close to the lower fixing platform, and a rubber anti-skid pad is installed on the outer wall of the lower fixing platform close to the upper fixing platform.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The bent pipe fixer has a rotating rod arranged on the outer wall of the bottom plate and a fixing nut threaded on the outer wall of the rotating rod. Under the action of the fixing nut, the rotating rod can be connected to the top plate, thereby forming a closed structure between the bottom plate and the top plate. When the equipment and the bent pipe need to be installed, the bent pipe can be easily inserted into the top of the lower fixed platform by rotating the rotating rod down from the outer wall of the top plate. There is no need to insert the bent pipe between the bottom plate and the top plate, which is very convenient and quick.

Under the action of the rotating shaft and the cam, the cam rotates around the outer wall of the rotating shaft. During the rotation of the cam, the outer wall of the cam pushes the upper fixed platform to move downward, thereby fixing the bent pipe under the action of the upper fixed platform and the lower fixed platform. In the whole process, it is only necessary to pull the operating lever, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] By means of a rotating rod 4 rotatably connected to the outer wall of the bottom plate 1 and a fixing nut 5 threadedly connected to the outer wall of the rotating rod 4, the bottom plate 1 and the top plate 3 can be connected under the action of the rotating rod 4 and the fixing nut 5. When the bent pipe needs to be fixed, the rotating rod 4 is flipped downward, and the bent pipe can be easily placed between the bottom plate 1 and the top plate 3.

[0023] In a preferred embodiment, there are four rotating rods 4 , and the four rotating rods 4 are evenly distributed and installed on the outer wall of the top plate 3 .

[0024] By means of the four rotating rods 4 arranged on the outer wall of the bottom plate 1, when the bent pipe needs to be placed between the bottom plate 1 and the top plate 3, the fixing nut 5 is screwed from the outer wall of the rotating rod 4 so that the outer wall of the fixing nut 5 moves outward from the outer wall of the rotating rod 4. At this time, the rotating rod 4 can be rotated so that the rotating rod 4 is detached from the outer wall of the top plate 3, and the bent pipe can be placed between the bottom plate 1 and the top plate 3 from one side of the rotating rod 4.

[0025] In a preferred embodiment, the distance between the inner walls of the fixing grooves 6 is equal to the diameter of the rotating rod 4 , and the length of the fixing nut 5 is greater than the distance between the inner walls of the fixing grooves 6 .

[0026] By setting the rotating rod 4 on the outer wall of the bottom plate 1, when the rotating rod 4 is fixed between the top plate 3, by rotating the fixing nut 5, the outer wall of the fixing nut 5 is tightly attached to the outer wall of the top plate 3. At this time, the rotating rod 4 will be fixed to the outer wall of the top plate 3 under the action of the fixing nut 5.

[0027] In a preferred embodiment, the inner cavity of the upper fixing platform 10 is provided with a plug hole, the inner wall diameter of the plug hole is equal to the outer wall diameter of the sliding rod 8 , and the diameter of the plug hole is smaller than the outer wall diameter of the limiting plate 9 .

[0028] By arranging the slide bar 8, the limit plate 9 and the upper fixed platform 10 on the outer wall of the top plate 3, the upper fixed platform 10 can move up and down on the outer wall of the slide bar 8 under the action of the slide bar 8 and the limit plate 9, but the upper fixed platform 10 will be prevented from detaching from the outer wall of the slide bar 8 under the action of the limit plate 9, so that the upper fixed platform 10 can better fix the bent pipe under the action of the cam 12.

[0029] In a preferred embodiment, the installation position of the rotating shaft 11 does not coincide with the center position of the cam 12 , and the rotating shaft 11 is installed at a position offset to one side of the center of the cam 12 .

[0030] By installing the rotating shaft 11 in the inner cavity of the top plate 3, and the position of the rotating shaft 11 does not coincide with the position of the center of the cam 12, when the cam 12 is rotated, the cam 12 rotates along the outer wall of the rotating shaft 11. In this way, during the rotation of the cam 12, the outer wall of the cam 12 will push the upper fixed platform 10 to move up and down along the outer wall of the slide rod 8, thereby achieving the fixation of the bent pipe with the cooperation of the upper fixed platform 10 and the lower fixed platform 7.

[0031] In a preferred embodiment, a rubber anti-skid pad is installed on the outer wall of the upper fixing platform 10 close to the lower fixing platform 7 , and a rubber anti-skid pad is installed on the outer wall of the lower fixing platform 7 close to the upper fixing platform 10 .

[0032] By installing rubber anti-skid pads on the outer walls of the upper fixing platform 10 and the lower fixing platform 7, when the bent pipe is placed on the outer wall of the lower fixing platform 7, the upper fixing platform 10 and the lower fixing platform 7, as well as the rubber anti-skid pads, can better achieve the effect of quickly fixing the bent pipe.

[0033] Working principle: during the use of the above-mentioned device, when the device is needed to fix the bent pipe, the fixing nut 5 is rotated to move the fixing nut 5 along the outer wall of the rotating rod 4, so that the outer wall of the fixing nut 5 is separated from the outer wall of the top plate 3. At this time, the rotating rod 4 can be rotated to separate the outer wall of the rotating rod 4 from the inner cavity of the top plate 3. At this time, the bent pipe can be placed from the outer wall of the side of the bottom plate 1 close to the rotating rod 4 to the top of the lower fixed platform 7. At this time, the rotating rod 4 is rotated again to make the outer wall of the rotating rod 4 contact with the outer wall of the fixing groove 6, and then the fixing nut 5 is rotated to make the fixing nut 5 The outer wall of the top plate 3 contacts with the outer wall of the top plate 3, and the rotating rod 4 can be fixed at this time, and the pipeline can be closed between the bottom plate 1 and the top plate 3. At this time, the operating rod 13 is pulled again, so that the operating rod 13 drives the cam 12 to rotate along the outer wall of the rotating shaft 11, so that during the rotation of the cam 12, the outer wall of the cam 12 contacts with the outer wall of the upper fixed platform 10, and the upper fixed platform 10 is pushed to move under the action of the outer wall of the cam 12, so that the outer wall of the upper fixed platform 10 contacts with the outer wall of the pipeline. At this time, the pipeline can be fixed under the action of the upper fixed platform 10 and the lower fixed platform 7, which is very quick and convenient.
