[0002] A pipe rack is a device used to support and fix pipes. It plays a vital role in the installation and transportation of pipes. In the construction of urban pipe networks, a large number of pipe racks are needed to support the pipes.

[0003] When laying pipes, it is necessary to first install the pipe rack at the construction site, and then install the pipes on the pipe rack. When using the existing pipe rack, the spacing of the internal limit brackets needs to be adjusted to adapt to the diameter of the pipe. When adjusting, the threaded rods connected to the brackets need to be rotated one by one to drive the brackets closer to the pipe to provide limit support for the pipe. This method of adjusting the spacing of the pipe brackets is relatively cumbersome and inconvenient to adjust the spacing of the pipe brackets. Utility Model Content

[0004] The purpose of the present invention is to provide a pipe placement rack with adjustable spacing, so as to solve the problem in the above background technology that the existing pipe brackets are not convenient for adjusting the spacing.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a pipe rack with adjustable spacing, comprising: a base and a locking mechanism, the top of the base is fixedly connected to a cylindrical rack, the inner side of the cylindrical rack is provided with a bracket,

[0006] A worm is movably connected to one side of the base through a bearing, and the outer side of the worm is meshed with a worm wheel, and the inside of the worm wheel is fixedly connected to a transmission shaft, and the middle part of the transmission shaft is fixedly connected to a driving gear, and the outer side of the driving gear is meshed with a driven gear, and the inside of the driven gear is fixedly connected to a connecting ring, and a plurality of groups of toggle grooves are provided inside the connecting ring, and the toggle grooves are slidably connected to the toggle rod, and both ends of the toggle rod are fixedly connected to a connecting frame, one end of the connecting frame is fixedly connected to the bracket, and one end of the worm is provided with a locking mechanism for driving the worm to rotate.

[0007] Preferably, both ends of the transmission shaft are movably connected to the base through bearings, the outer side of the connecting frame is slidably connected to the cylindrical frame, and a sliding groove matching the connecting frame is provided inside the cylindrical frame.

[0008] Preferably, the engaging mechanism includes a rectangular block fixedly connected to one end of the worm, and one end of the rectangular block is fixedly connected to a round rod.

[0009] Preferably, one end of the round rod is fixedly connected to a limiting rod, and the outer side of the limiting rod is slidably connected to a handle.

[0010] Preferably, a spring is sleeved on the outer side of the limiting rod, and one end of the spring is connected to the handle.

[0011] Preferably, a rectangular groove is provided inside the handle, and the rectangular groove is engaged and connected with the rectangular block.

[0012] Compared with the existing technology, the beneficial effect of the pipe rack with adjustable spacing is that when laying pipes, the pipe rack needs to be installed on the construction site first, and then the pipes are installed on the pipe rack. When adjusting the spacing of the brackets in the pipe rack, the locking mechanism is pushed to engage with the worm, and then the handle is turned to drive the round rod and the worm to rotate, so that the worm is engaged with the worm gear, driving the worm gear to rotate. When the worm gear rotates, the drive gear can be driven to rotate through the transmission shaft, so that the drive gear is engaged with the driven gear. When the driven gear rotates, the toggle rod can be moved by toggling the internal multiple groups of inclined toggle grooves, so that the toggle rod drives the connecting rack to move. The multiple groups of connecting racks will drive the multiple groups of brackets to move synchronously, so that the spacing of the multiple groups of brackets changes, so as to adapt to the diameter of the installed pipes. In this way, the above operation can facilitate the adjustment of the spacing of the pipe rack to adapt to pipes of different diameters. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figures 1-4 The utility model provides a technical solution: a pipe rack with adjustable spacing, including: a pipe rack with adjustable spacing, including: a base 1 and a clamping mechanism 14, the top of the base 1 is fixedly connected to a cylindrical frame 2, and the inner side of the cylindrical frame 2 is provided with a bracket 3,

[0020] A worm 4 is movably connected to one side of the base 1 through a bearing, and a worm wheel 5 is meshedly connected to the outside of the worm 4. A transmission shaft 7 is fixedly connected to the inside of the worm wheel 5, and a driving gear 6 is fixedly connected to the middle part of the transmission shaft 7. The outside of the driving gear 6 is meshedly connected to the driven gear 8, and a connecting ring 9 is fixedly connected to the inside of the driven gear 8. A plurality of groups of toggle grooves 10 are provided inside the connecting ring 9, and the toggle grooves 10 are slidably connected to the toggle rod 11. Both ends of the toggle rod 11 are fixedly connected to a connecting frame 12, and one end of the connecting frame 12 is fixedly connected to the bracket 3. One end of the worm 4 is provided with a locking mechanism 14 for driving the worm 4 to rotate;

[0021] The two ends of the transmission shaft 7 are movably connected to the base 1 through bearings, the outer side of the connecting frame 12 is slidably connected to the cylindrical frame 2, and the interior of the cylindrical frame 2 is provided with a slide groove matching the connecting frame 12. The connecting frame 12 and the cylindrical frame 2 form a sliding structure, and the driving gear 6 and the driven gear 8 form an engaged transmission structure; the locking mechanism 14 includes a rectangular block 141 fixedly connected to one end of the worm 4, and one end of the rectangular block 141 is fixedly connected to a round rod 142; one end of the round rod 142 is fixedly connected to a limited The positioning rod 143 has a handle 145 slidably connected to the outer side of the limiting rod 143; a spring 144 is sleeved on the outer side of the limiting rod 143, and one end of the spring 144 is connected to the handle 145; a rectangular groove 146 is provided inside the handle 145, and the rectangular groove 146 is engaged with the rectangular block 141, and a through groove is provided inside the handle 145, and the through groove is slidably connected to the limiting rod 143, and the limiting rod 143 and the handle 145 constitute a sliding structure, and the material of the anti-slip groove 13 is rubber.

[0022] In specific implementation, when laying pipes, it is necessary to first install the pipe rack on the construction site, and then install the pipes on the pipe rack. When adjusting the spacing of the brackets 3 in the pipe rack, by pushing the handle 145 in the locking mechanism 14 to slide on the outside of the limit rod 143, the handle 145 will squeeze the spring 144. When the rectangular groove 146 inside the handle 145 is engaged with the rectangular block 141 at one end of the round rod 142, the handle 145 can be rotated to drive the round rod 142 and the worm 4 to rotate.

[0023] When the rubber anti-slip groove 13 inside the bracket 3 is in close contact with the outer wall of the pipe, the friction with the pipe can be increased to stabilize and limit it, and prevent the bracket 3 from making hard contact with the pipe and causing damage to the pipe. After the adjustment is completed, the handle 145 can be released. At this time, the spring 144 will reset and push the handle 145 out of the engagement with the rectangular block 141. At this time, if the handle 145 is accidentally touched, the handle 145 will idle and cannot drive the worm 4 to rotate, preventing the bracket 3 from moving. In this way, the above operation can facilitate the adjustment of the spacing of the pipe rack to adapt to pipes of different diameters.
