[0031] Embodiment 1

[0032] Refer to Figures 1 to 4, As an alternative embodiment of the present application, this embodiment discloses a heating and ventilation pipe installation bracket, including a support crossbeam 1. Along the length direction of the support crossbeam 1, connection holes are provided at both ends of the support crossbeam 1. At the same time, a suspension rod 2 is also provided. The suspension rod 2 includes a first-stage suspension rod 201 and a second-stage suspension rod 202. Along the axial direction of the first-stage suspension rod 201, a plug-in hole 18 is provided at the bottom end of the first-stage suspension rod 201. The plug-in hole 18 is a counterbore, and its open end is provided on the bottom end face of the first-stage suspension rod 201; the second-stage suspension rod 202 is slidably inserted into the plug-in hole 18 of the first-stage suspension rod 201; at the same time, a plurality of first adjustment holes 203 are provided on the first-stage suspension rod 201, and a plurality of second adjustment holes are provided on the second-stage suspension rod 202. Each of the first adjustment holes corresponds to each of the second adjustment holes one by one;

[0033] It should be noted that the correspondence here means that the first adjustment hole 203 and the second adjustment hole 204 are coaxial, and the corresponding first adjustment hole and second adjustment hole are connected by a connecting bolt 205;

[0034] Through the above structural settings, the length of the suspension rod 2 can be adjusted in multiple gears, and then the height of the support crossbeam 1 can be adjusted to meet different installation requirements, and the adjustment method is simple and reliable.

[0035] An expansion screw 4 for connecting to an external structure is provided at the top of the first-stage suspension rod 201; the bottom end of the second-stage suspension rod 202 is connected to the support crossbeam 1 through an adjustment module. The adjustment module includes a support sleeve 5. A plurality of adjustment nuts 6 are fixedly provided in the support sleeve 5. Each of the adjustment nuts 6 is threadedly connected to the second-stage suspension rod 202. Preferably, 2-3 adjustment nuts 6 are provided. Along the axial direction of the support sleeve 5, each adjustment nut 6 is respectively arranged at the two ends and the middle position;

[0036] Along the vertical direction, the top surface of the support sleeve 5 is in close contact with the bottom surface of the support crossbeam 1. At the same time, an anti-slip rubber pad can be added to the top surface of the support sleeve 5; after installation, the anti-slip rubber pad is in close contact with the bottom surface of the support crossbeam 1;

[0037] At the same time, the adjustment module further includes a limit nut 7. The limit nut 7 is threadedly connected to the second-stage suspension rod 202. Along the vertical direction, the limit nut 7 is in close contact with the top surface of the support crossbeam 1;

[0038] In the above structure, through the fixed connection between the support sleeve 5 and the adjustment nut 6, on the one hand, the coaxiality between the support sleeve 5 and the second suspension rod 202 can be ensured to prevent it from tilting outward; on the other hand, during the adjustment process, by rotating the support sleeve 5, all the adjustment nuts 6 can be rotated, and the adjustment is more convenient;

[0039] Secondly, precise adjustment of the position of the support crossbeam 1 can be achieved through the control of the adjustment module. Its rough adjustment cooperation with the first adjustment hole 203 and the second adjustment hole 204 realizes the control of the position of the support crossbeam 1, which not only simplifies the adjustment process but also makes the position control more precise.

[0040] Furthermore, there is still a slide rail 11 on the support crossbeam 1. The slide rail 11 is arranged along the length direction of the support crossbeam 1. A chute 12 is provided on the support crossbeam 1, and the cross-section of the chute 12 is of a T-shaped or dovetail-shaped structure;

[0041] Along the length direction of the slide rail 11, both ends of the chute 12 penetrate through both end faces of the slide rail 11 to form an open structure to facilitate the installation of various accessory components; at the same time, sealing blocks 14 are provided at both open ends of the chute 12;

[0042] The mounting bracket further includes a plurality of support seats 8. The bottom surface of each support seat 8 is integrally connected with a slider 13. The outer shape of the slider 13 is the same as the cross-section of the chute 12, and the slider 13 is slidably inserted into the chute 12; a limiting groove 9 is provided on the top surface of each of these support seats 8. The limiting groove 9 is used to place the HVAC pipe to be installed, and its outer shape is the same as that of the HVAC pipe to be installed. That is, if the HVAC pipe is a circular pipe, the limiting groove 9 is of an arc structure; if the HVAC pipe is square, the limiting groove 9 is also square;

[0043] At the same time, a plurality of limiting elastic pieces 10 are provided on the inner surface of the limiting groove 9. Each of the limiting elastic pieces 10 is of an L-shaped structure, one end of which is connected to the inner wall of the limiting groove 9, and the other end is in a free state;

[0044] Since the structural parameters of the limiting groove 9 are fixed, while the specifications of the HVAC pipe may change, the setting of the limiting elastic pieces 10 can better clamp and fix the HVAC pipe, ensuring the stability of its installation. At the same time, the limiting elastic pieces 10 also have a certain elasticity to meet the installation requirements of different specifications of HVAC pipes.

[0045] Furthermore, a limiting belt 3 is also provided on the support crossbeam 1. The limiting belt 3 is made of a plastic tie strap or can also be made of other flexible belts; the limiting belt 3 is arranged along the length direction of the support crossbeam 1. Along the length direction of the limiting belt 3, a connecting pin shaft 15 is provided at one end of the limiting belt 3, and a connecting ear plate 16 is provided on the support crossbeam 1; there are two connecting ear plates 16 in total.

Connecting pin holes 20 are provided on both of the connecting ear plates 16, and both ends of the connecting pin shaft 15 are respectively inserted into the two connecting pin holes;

[0046] On one side of the two connecting ear plates 16 facing the suspension rod 2, a clamping groove 21 is further provided. Along the radial direction of the connecting pin hole 20, the clamping groove 21 communicates the connecting pin hole with the outside. Through the clamping groove 21, the quick connection between the connecting pin shaft 15 and the connecting ear plate 16 can be realized while ensuring the connection stability of the limiting belt 3, and the quick installation and replacement of the limiting block can be realized;

[0047] On the other end of the limiting belt 3, a plurality of limiting ratchet teeth 17 are provided. At the same time, a plug hole 18 is provided on the support cross beam 1, and a pawl 19 is provided in the plug hole 18. It should be noted that the limiting ratchet teeth 17 are arranged in parallel along the length direction of the limiting belt 3. The limiting ratchet teeth 17 can be arranged on the top surface of the limiting belt 3 or on the bottom surface, and are specifically arranged according to the position of the remembered object, but it is necessary to ensure that the limiting ratchet teeth 17 can cooperate with the pawl 19 for limiting;

[0048] Furthermore, the mounting bracket further includes a plurality of limiting seats 22. A plugging chute 23 is provided on each of the limiting seats 22, and the limiting belt 3 is slidably inserted into each of the plugging chutes 23; A clamping groove 24 adapted to the HVAC pipe to be installed is provided on each of the limiting seats 22. A plurality of limiting elastic pieces 10 are provided on the inner wall of the clamping groove 24. Each of the limiting elastic pieces 10 has an L-shaped structure, one end of which is connected to the inner wall of the limiting groove 9, and the other end is in a free state;

[0049] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
