Description

Technical Field

[0001] This utility model relates to the field of HVAC duct technology, specifically to a HVAC duct fixing mechanism. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) pipes are a type of pipe used in HVAC systems. HVAC pipes are mainly used to transport hot and cold media (such as hot water, cold water, steam, air, etc.) to various areas that require temperature regulation, and therefore they are widely used in residential, commercial, and industrial buildings.

[0003] When installing HVAC ducts, a fixing mechanism is needed to position and install them to facilitate better installation. However, most existing fixing mechanisms do not have adjustment functions, which makes it difficult for them to adapt to pipes of different diameters, thus reducing their practicality. Therefore, a new HVAC duct fixing mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a heating, ventilation, and air conditioning (HVAC) pipe fixing mechanism with advantages such as adjustable function. It solves the problem that when installing HVAC pipes, a fixing mechanism is needed to position and install the pipes so that they can be installed more effectively. However, most existing fixing mechanisms do not have adjustable function, which makes it difficult for the fixing mechanism to adapt to pipes of different diameters, thus reducing the practicality of the fixing mechanism.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A heating, ventilation and air conditioning (HVAC) pipe fixing mechanism includes a housing, a motor fixedly connected inside the housing, a vertical shaft fixedly connected to the output end of the motor, a first gear fixedly connected to the outer side of the vertical shaft, three threaded rods rotatably connected inside the housing, a second gear fixedly connected to one end of each of the three threaded rods, the first gear meshing with the three second gears, a moving block threadedly connected to the outer side of each of the three threaded rods, a load-bearing block fixedly connected to the front of each of the three moving blocks, a vertical block fixedly connected to the outer side of each of the three load-bearing blocks, and a friction block fixedly connected to the outer side of each of the three vertical blocks.

[0008] The beneficial effects of this utility model are: through the threaded rod and the moving block, the moving block can drive the load-bearing block and the vertical block to move, thereby making the friction block contact the inner wall of the pipe, and thus making the friction block clamp and fix the pipe, so as to facilitate the installation of the pipe.

[0009] This HVAC duct fixing mechanism has the advantage of adjustable function.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, all three load-bearing blocks are arranged in a trapezoidal shape, and all three friction blocks are arranged in an arc shape.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that, through the trapezoidal arrangement, the three load-bearing blocks can have better load-bearing function.

[0013] Furthermore, the three friction blocks are provided with the same tube on their outer sides, and the tube is located on the front of the outer casing.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the friction block enables the inner side of the pipe to be subjected to force for limiting, so as to facilitate the installation of the pipe.

[0015] Furthermore, the interior of the outer casing is fixedly connected with three push rods, and the back of each of the three push rods is fixedly connected with a top block, and the three top blocks are all arranged in a trapezoidal shape.

[0016] The advantage of adopting the above-mentioned further solution is that the top block can be moved by the push rod, and the outer shell can be raised and lowered.

[0017] Furthermore, three casters are fixedly connected to the back of the outer casing, and all three casters have a self-locking function.

[0018] The advantage of adopting the above-mentioned further solution is that the outer casing can be moved by the casters.

[0019] Furthermore, a push handle is fixedly connected to the outer side of the outer shell, and the push handle is arranged at an angle.

[0020] The advantage of adopting the above-mentioned further solution is that the outer casing can be easily pushed by force through the push handle. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the embodiments, by Figure 1-4 The present invention provides a heating, ventilation, and air conditioning (HVAC) pipe fixing mechanism, comprising a housing 1, a motor 2 fixedly connected inside the housing 1, a vertical shaft 3 fixedly connected to the output end of the motor 2, a first gear 4 fixedly connected to the outer side of the vertical shaft 3, three threaded rods 5 rotatably connected inside the housing 1, a second gear 6 fixedly connected to one end of each of the three threaded rods 5, the first gear 4 meshing with the three second gears 6, a moving block 7 threadedly connected to the outer side of each of the three threaded rods 5, a load-bearing block 8 fixedly connected to the front of each of the three moving blocks 7, a vertical block 9 fixedly connected to the outer side of each of the three load-bearing blocks 8, and a friction block 10 fixedly connected to the outer side of each of the three vertical blocks 9.

[0028] The three load-bearing blocks 8 are all arranged in a trapezoidal shape, and the three friction blocks 10 are all arranged in an arc shape;

[0029] The trapezoidal design allows the three load-bearing blocks 8 to have better load-bearing capacity.

[0030] The three friction blocks 10 are provided with the same tube 11 on their outer sides, and the tube 11 is located on the front of the outer shell 1;

[0031] The friction block 10 allows the inner side of the tube body 11 to be subjected to force for limiting, so as to facilitate the installation of the tube body 11.

[0032] The inner casing 1 has three push rods 12 fixedly connected to it. The back of each of the three push rods 12 is fixedly connected to a top block 13. The three top blocks 13 are all arranged in a trapezoidal shape.

[0033] The push rod 12 allows the top block 13 to move, enabling the outer casing 1 to rise and fall.

[0034] Three casters 14 are fixedly connected to the back of the outer casing 1, and all three casters 14 have a self-locking function;

[0035] The outer casing 1 can be moved by the casters 14;

[0036] A push handle 15 is fixedly connected to the outer side of the outer casing 1, and the push handle 15 is set at an angle.

[0037] The push handle 15 makes it easy to push the outer casing 1 under force.

[0038] Working principle:

[0039] Start motor 2, causing its output end to drive the first gear 4 to rotate via the vertical shaft 3. The rotation of the first gear 4 drives the three second gears 6 to rotate, which in turn drives the three threaded rods 5 to rotate. The three threaded rods 5 then drive the three moving blocks 7 to move towards the center / edge. The three moving blocks 7 then drive the vertical block 9 and friction block 10 to move via the load-bearing block 8, causing the friction block 10 to come into contact with the tube body 11. This allows the tube body 11 to be limited at the top of the outer shell 1. Then, push the outer shell 1 to move via the push handle 15, allowing the outer shell 1 to move via the three universal wheels 14. When the tube body 11 is in the installation position, lock the universal wheels 14 and activate the push rod 12, causing the push rod 12 to drive the top block 13 to move. This causes the top block 13 to come into contact with the ground and lift the outer shell 1, allowing the outer shell 1 to move the tube body 11 upwards, facilitating the installation and connection of the tube body 11.
