Description

Technical Field

[0001] This utility model relates to the field of HVAC pipe installation technology, specifically to an HVAC pipe installation structure for HVAC engineering. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) pipes are pipes used to transport air, water, or refrigerant in HVAC systems, such as underfloor heating pipes, exhaust pipes, and condensate pipes.

[0003] Most existing HVAC pipes are coiled, and they are usually positioned using clamps, such as those used for underfloor heating pipes. However, since the pipes are positioned visually, human error can lead to uneven spacing between adjacent parallel pipes. Some pipes are too close together, while others are too far apart. And since the clamps are not easy to remove after positioning, uneven heat transfer in certain areas can easily occur. Utility Model Content

[0004] The technical problem this invention aims to solve is that human error causes uneven pipe spacing, and the positioning clamps are inconvenient to disassemble after positioning, which easily leads to uneven local heat transfer.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a heating and ventilation pipe installation structure for heating and ventilation engineering, including an installation rod and a flexible positioning band. The installation rod is provided with a positioning block in the middle, and several sliding blocks are slidably provided on both sides of the positioning block. The installation rod is provided with a spacing adjustment component that can drive the sliding blocks to move along the axial direction of the installation rod to adjust the spacing between the sliding blocks and between the sliding blocks and the positioning block. The positioning block and the sliding block are respectively provided with an installation plate. One end of the positioning band is provided on one side of the installation plate, and the other side of the installation plate is provided with a limiting hole. The limiting hole is provided with a limiting component that can adjust and limit the other end of the positioning band according to the diameter of the heating and ventilation pipe.

[0006] Furthermore, the spacing adjustment assembly includes a fixed shaft disposed between the positioning block and the mounting rod, a first hinge rod is provided on the fixed shaft with a composite hinge, the middle of the first hinge rod is hinged to the fixed shaft, and the ends of the first hinge rod are respectively provided with second hinge rods through the hinge shaft. The sliding block is provided with a movable shaft, and the two sides of the mounting rod are respectively provided with sliding grooves that cooperate with the ends of the movable shaft. The movable shaft is compositely hinged to the second hinge rod.

[0007] Furthermore, each of the sliding blocks has a threaded hole on one side, and a locking bolt is provided in the threaded hole. The locking bolt passes through the threaded hole through the thread and abuts against the side wall of the mounting rod at its end.

[0008] Furthermore, the limiting component includes a ratchet rack disposed at the free end of the positioning belt, a connecting shaft disposed in the limiting hole, a limiting block hinged on the connecting shaft, a spring disposed between one end of the limiting block and the side wall of the limiting hole, and a locking block disposed at the other end to cooperate with the ratchet rack for limiting.

[0009] Furthermore, the limiting hole and the positioning band connection line are arranged parallel to the axial direction of the mounting rod, and a pad is provided between the limiting hole and the positioning band connection point on the mounting plate. The top of the pad is provided with a triangular groove or an arc-shaped groove.

[0010] Furthermore, a lever is provided at the top of the limiting block.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] 1. After the positioning belt passes around the HVAC pipe, it is inserted into the limiting hole. The limiting component can make the positioning belt stably limit the HVAC pipes of different diameters on the mounting plate, which can improve its practicality.

[0013] 2. By adjusting the components, the sliding block and its mounting plate can be driven to slide along the axial direction of the mounting rod, thereby adjusting the distance between the positioning block and the sliding block, as well as between the sliding blocks. This allows the HVAC pipes to be evenly distributed, avoiding uneven distribution of the HVAC pipes during manual installation, which can lead to localized overheating or underheating of the underfloor heating system.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 A heating and ventilation pipe installation structure for heating and ventilation engineering includes an installation rod 1 and a flexible positioning band 2. The installation rod 1 has a positioning block 3 in the middle. Several sliding blocks 4 are slidably provided on both sides of the positioning block 3. The positioning block 3 and the sliding blocks are respectively provided with an installation plate 6. One end of the positioning band 2 is provided on one side of the installation plate 6. The other side of the installation plate 6 is provided with a limiting hole 7. The limiting hole 7 is provided with a limiting component 8 that can adjust and limit the other end of the positioning band 2 according to the diameter of the heating and ventilation pipe. The limiting component 8 includes a ratchet 16 provided at the free end of the positioning band 2. A connecting shaft 17 is provided in the limiting hole 7. A limiting block 18 is hinged on the connecting shaft 17. A spring 19 is provided between one end of the limiting block 18 and the side wall of the limiting hole 7. The other end is provided with a locking block 20 that cooperates with the ratchet 16 for limiting. A lever 22 is provided on the top of the limiting block 18.

[0021] First, place the HVAC pipes in the middle of mounting plate 6;

[0022] Then, after the positioning band 2 is wrapped around the HVAC pipe, the flexible structure of the positioning band 2 increases its contact area with the HVAC pipe and causes the ratchet 16 at its end to pass through the limiting hole 7. As the ratchet 16 moves down, the drive block 20 rotates counterclockwise around the connecting shaft 17. At this time, the spring 19 is stretched and stores force.

[0023] Until the positioning band covers the top of the two pairs of HVAC pipes, the ratchet 16 can no longer move down. At this time, under the reset action of the spring 19, the locking block 20 cooperates with the ratchet 16 again to achieve the limit.

[0024] When disassembly is required, the limit block 18 can be driven to rotate counterclockwise by the lever 22, and the limit rod will drive the locking block 20 to no longer engage with the ratchet 16, thus facilitating the removal of the ratchet 16 from the limit hole 7 and disassembling the HVAC pipes, avoiding the damaging disassembly of traditional installation structures.

[0025] Combined with appendix Figure 3 and attached Figure 4 The limiting hole 7 and the positioning band 2 are connected in parallel to the axial arrangement of the mounting rod 1. The mounting plate 6 is provided with a pad 21 between the limiting hole 7 and the positioning band 2. The top of the pad 21 is provided with an arc-shaped groove.

[0026] The installation of pad 21 helps to enhance the stability of the bottom positioning of HVAC pipes.

[0027] Combined with appendix Figure 1 The mounting rod 1 is provided with a spacing adjustment component 5, which can drive the sliding block 4 to move along the axial direction of the mounting rod 1 to adjust the spacing between the sliding blocks 4 and between the sliding block 4 and the positioning block 3. The spacing adjustment component 5 includes a fixed shaft 9 located between the positioning block 3 and the mounting rod 1. A first hinge rod 10 is provided on the fixed shaft 9. The middle of the first hinge rod 10 is connected to the fixed shaft 9. The ends of the first hinge rod 10 are respectively provided with second hinge rods 11 through the hinge shaft. The sliding block 4 is provided with a moving shaft 12. The two sides of the mounting rod 1 are respectively provided with sliding grooves 13 that cooperate with the ends of the moving shaft 12. The second hinge rod 11 is compoundly hinged on the moving shaft 12.

[0028] Combined with appendix Figure 1 and attached Figure 2 The sliding block 4 is provided with threaded holes 14 on one side, and a locking bolt 15 is provided in the threaded hole 14. The locking bolt 15 passes through the threaded hole 14 through the thread and abuts against the side wall of the mounting rod 1 at its end.

[0029] When it is necessary to adjust the distance between the sliding blocks 4 and between the sliding block 4 and the positioning block 3, one of the sliding blocks 4 can be moved. The sliding block 4 slides along the direction of the slide groove 13. The first hinge rod 10 and the second hinge rod 11 are symmetrically arranged and have a scissor-type structure. This drives each sliding block 4 to adjust the distance between the sliding blocks 4 and between the sliding block 4 and the positioning block 3 with the positioning block 3 as the center. The sliding blocks 4 and the positioning block 3 drive the mounting plate 6 to adjust the distance at equal intervals. Then, the locking bolt 15 passes through the threaded hole 14 through the thread and abuts against the side wall of the mounting rod 1 at its end, thereby realizing the positioning of the sliding block 4.
