Technical Field

[0001] The utility model belongs to the technical field of devices for pipeline construction, in particular to a fixing bracket for fixing heating pipelines. Background Art

[0002] During the interior decoration of a building, it is necessary to lay heating pipelines in the house. The heating pipelines can provide heat for the house in winter. When installing the pipelines on the wall, they need to be fixed. The existing pipeline fixing method is to use a clamp to fix it. The clamp is nailed into the wall through nails. After long-term use, it is easy to fall off, which may cause the pipeline to lose support and fall down. At the same time, the clamp nailed into the wall is not conducive to subsequent pipeline inspection and maintenance. At the same time, the diameter of the existing clamp is fixed. When fixing pipelines with different diameters, different sizes of clamps need to be replaced. Therefore, construction workers need to carry various sizes of clamps for pipeline construction, and carrying too many clamps is heavy and inconvenient for construction workers.

The insertion rod assembly 1 is slidably connected to the sliding sleeve assembly 2, and the sliding sleeve assembly 2 is slidably connected to the clamping unit 3.

[0020] The plug rod assembly 1 includes: a plug rod 1-1, a fixing unit 1-2, a first semi-ring 1-3, and a limiting groove 1-4. The plug rod 1-1 is rotatably connected to the fixing unit 1-2. A plurality of the fixing units 1-2 are provided. A first semi-ring 1-3 is fixed to the upper end of the plug rod 1-1. A limiting groove 1-4 is fixed to the side surface of the plug rod 1-1. Wedge-shaped protrusions are continuously provided on the inner bottom surface of the limiting groove 1-4.

[0021] Each of the plurality of fixing units 1-2 includes: a linkage rod 1-2-1 and a fixing plate 1-2-2. Two linkage rods 1-2-1 are provided. The opposite ends of the two linkage rods 1-2-1 are rotatably connected to the fixing plate 1-2-2. The other end of one of the linkage rods 1-2-1 is rotatably connected to the plug rod 1-1. A plurality of thorn cones are provided on the top surface of the fixing plate 1-2-2.

[0022] The sliding sleeve assembly 2 includes: a sliding sleeve 2-1, a sliding groove long through hole 2-2, a setscrew 2-3, a sliding column 2-4, and a spring 2-5. The sliding sleeve 2-1 slidably penetrates into the plug rod 1-1. The other end of the other linkage rod 1-2-1 is rotatably connected to the sliding sleeve 2-1. A sliding groove long through hole 2-2 is provided on the top surface of the sliding sleeve 2-1. One end of the sliding groove long through hole 2-2 communicates with one side wall of the sliding sleeve 2-1. The first semi-ring 1-3 is arranged in the sliding groove long through hole 2-2. The setscrew 2-3 is screwed and connected to the side surface of the sliding sleeve 2-1. A sliding column 2-4 is horizontally and fixedly connected to the lower end of the sliding sleeve 2-1. A limiting protrusion is provided on the side wall of the sliding column 2-4 along its length direction. A spring 2-5 is sleeved on the sliding column 2-4.

[0023] The clamping unit 3 includes: a sliding frame 3-1, a support column 3-2, and a second semi-ring 3-3. The sliding frame 3-1 is slidably connected to the sliding column 2-4. Two support columns 3-2 are symmetrically fixed to the sliding frame 3-1. A second semi-ring 3-3 is fixed to each of the support columns 3-2. The second semi-ring 3-3 and the first semi-ring 1-3 are symmetrically arranged. The plug rod 1-1 is arranged between the two support columns 3-2.

[0024] The working principle of the present utility model is:

[0025] During use, drill a hole in the wall where the pipe needs to be fixed, then insert the plug rod assembly 1 into the drilled hole, push the sliding sleeve 2-1 to move leftward along the plug rod 1-1, and jack up the fixing plate 1-2-2 through the two linkage rods 1-2-1, so that the fixing plate 1-2-2 abuts against the inner wall of the hole to complete the fixation. At the same time, multiple barbs penetrate into the wall to increase the friction to prevent falling off. After the fixation is completed, tighten the setscrew 2-3 so that the setscrew 2-3 abuts against the wedge-shaped protrusion arranged on the bottom surface of the limit groove 1-4. Through the cooperation limit between the wedge-shaped protrusion and the setscrew 2-3, the displacement of the sliding sleeve 2-1 can be prevented to avoid loosening. When the device needs to be disassembled, loosen the setscrew 2-3 and then slide the sliding sleeve 2-1 in the reverse direction to take out the device, which can be reused. When fixing the pipe, pull the half ring two 3-3 to drive the sliding frame 3-1 to slide along the sliding column 2-4 through the support column 3-2 and compress the spring 2-5 at the same time. The limit protrusion arranged on the side surface of the sliding column 2-4 restricts the rotation of the sliding frame 3-1. At this time, place the pipe to be fixed in the half ring one 1-3, and then loosen the half ring two 3-3. Drive the half ring two 3-3 to reset through the action of the spring 2-5, and cooperate with the half ring one 1-3 to clamp the pipe for fixation. The staggered arrangement of the half ring two 3-3 and the half ring one 1-3 can fix pipes with different diameters and has strong versatility. When the pipe needs to be taken out for maintenance, pull the half ring two 3-3 to separate it from the half ring one 1-3 and take out the pipe. The half ring one 1-3 plays a role in limiting the sliding sleeve 2-1 and restricts the rotation of the sliding sleeve 2-1.

[0026] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
