Description

Technical Field

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

[0002] Heating, ventilation, and air conditioning (HVAC) piping is a core component of HVAC engineering used to transport air, water, or other media. HVAC piping includes air ducts, water pipes, steam pipes, and other pipes.

[0003] When laying HVAC ducts, brackets are needed to suspend and install them. Most existing HVAC brackets have a fixed height, but the height of HVAC ducts varies during actual installation. Fixed-height HVAC brackets have low adaptability. Therefore, this paper provides a type of HVAC bracket for HVAC engineering. Utility Model Content

[0004] The purpose of this utility model is to provide a heating and ventilation support for heating and ventilation engineering in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating and ventilation support for heating and ventilation engineering, comprising a support assembly, wherein the support assembly consists of two uprights, a straight groove, a concave cross arm, a screw hole, and a locking screw;

[0006] The concave cross arms are symmetrically distributed between the two uprights, and the screw holes are symmetrically opened on both sides of the two vertical parts of the concave cross arms and are completely tubular screw holes.

[0007] The straight groove is opened on one side of the upright and extends to the other side of the upright;

[0008] When the locking screw passes through the straight slot and is screwed into the screw hole thread, it fits tightly against the side of the upright, thereby achieving vertical locking of the concave cross arm and the upright.

[0009] A limiting component is also provided on the outer side of the lateral portion of the concave cross arm. The limiting component is used to clamp and limit the HVAC pipe located at the upper end of the lateral portion of the concave cross arm.

[0010] As a further improvement of this utility model: the limiting component includes an arc-shaped clamp and a limiting slide;

[0011] The limiting slide is fixed to the bottom end of the arc-shaped clamping plate. The limiting slide is horizontally slidably connected to the outer side of the transverse part of the concave cross arm. Two sets of arc-shaped clamping plates and limiting slides are symmetrically arranged around the center line of the concave cross arm.

[0012] The two sets of arc-shaped clamps and limiting slides are close to each other to clamp and limit the HVAC pipes.

[0013] As a further improvement of this utility model: the locking screw passes through the vertical part of the concave horizontal arm and fits tightly against the side of the arc-shaped clamping plate. When the locking screw is tightened, it is used to provide power for the movement of the arc-shaped clamping plate.

[0014] As a further improvement of this utility model: the inner diameter of the semi-straight groove structure formed by the two arc-shaped clamps matches the outer diameter of the HVAC pipe, and when the arc-shaped clamps are in contact with the HVAC pipe, the locking screw is in close contact with the upright.

[0015] As a further embodiment of this utility model: the locking screw is located on the outer side of the part between the concave horizontal arm and the arc-shaped clamping plate and is threaded with a reinforcing nut. The reinforcing nut fits against the side of the vertical part of the concave horizontal arm to lock and reinforce the position of the locking screw.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting up a modular support assembly, the concave cross arm and the upright can be assembled according to the distance from the bottom of the HVAC duct to the building roof, thereby supporting HVAC ducts at different installation heights. At the same time, while fixing the position of the concave cross arm, the clamping and limiting of the HVAC duct is also achieved simultaneously. The overall operation steps are reduced, which can effectively improve the installation efficiency. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-3In this embodiment of the utility model, a heating and ventilation support for heating and ventilation engineering includes a support assembly 1, which consists of two uprights 101, a straight groove 102, a concave cross arm 103, a screw hole 104, and a locking screw 105.

[0024] The concave cross arm 103 is symmetrically distributed between the two uprights 101, and the screw holes 104 are symmetrically opened on both sides of the two vertical parts of the concave cross arm 103 and are completely pipe screw holes 104.

[0025] A straight groove 102 is opened on one side of the upright 101 and extends through to the other side of the upright 101;

[0026] When the locking screw 105 passes through the straight slot 102 and is screwed into the screw hole 104, it fits tightly against the side of the upright 101 to achieve vertical locking of the concave cross arm 103 and the upright 101.

[0027] A limiting component 2 is also provided on the outer side of the lateral portion of the concave horizontal arm 103. The limiting component 2 is used to clamp and limit the HVAC pipe 3 located at the upper end of the lateral portion of the concave horizontal arm 103.

[0028] The limiting component 2 includes an arc-shaped clamp 201 and a limiting slide 202;

[0029] The limiting slide 202 is fixed to the bottom end of the arc-shaped clamp 201. The limiting slide 202 is horizontally slidably connected to the outer side of the transverse part of the concave cross arm 103. Two sets of arc-shaped clamp 201 and limiting slide 202 are symmetrically arranged around the center line of the concave cross arm 103.

[0030] Two sets of arc-shaped clamping plates 201 and limiting slides 202 are placed close to each other to clamp and limit the HVAC pipe 3;

[0031] The locking screw 105 passes through the vertical part of the concave horizontal arm 103 and fits tightly against the side of the arc-shaped clamp 201. When the locking screw 105 is tightened, it is used to provide power for the movement of the arc-shaped clamp 201.

[0032] The inner diameter of the semi-straight groove structure formed by the two arc-shaped clamps 201 matches the outer diameter of the HVAC pipe 3, and when the arc-shaped clamps 201 are in contact with the HVAC pipe 3, the locking screw 105 is tightly in contact with the upright 101.

[0033] In this embodiment, it should be noted that the top of the upright 101 is integrally formed with an installation plate for the installation and fixing of expansion bolts, and the straight grooves 102 are evenly arranged vertically with multiple grooves.

[0034] The operating procedure for this HVAC bracket is as follows:

[0035] First, based on the distance from the bottom of the HVAC pipe 3 to the building roof, assemble the concave horizontal arm 103 and the upright 101. Then, use the locking screw 105 to pass through a straight groove 102 and connect it with the screw hole 104. The distance from the bottom of the straight groove 102 to the top of the upright 101 is slightly greater than the distance from the bottom of the HVAC pipe 3 to the building roof.

[0036] Then, the bracket can be sleeved from the bottom of the HVAC pipe 3 upwards, and the top of the upright 101 can be aligned with the roof of the building to determine the position of the installation hole. After that, the bracket is removed and holes are drilled in the roof of the building. Then, the bracket is fixed to the roof of the building with expansion bolts. (It should be noted that the limiting component 2 is installed on the concave cross arm 103 when it leaves the factory. During the installation process, the distance between the two limiting components 2 is greater than the diameter of the HVAC pipe 3, so it will not interfere with the HVAC pipe 3.)

[0037] After the bracket is fixed, lift the concave horizontal arm 103 upwards so that it fits against the bottom of the HVAC pipe 3. During this process, the locking screw 105 moves upwards along the straight groove 102. Then, tighten the locking screw 105 with a tool. The locking screw 105 pushes the arc-shaped clamp 201 horizontally closer to the HVAC pipe 3. Finally, the arc-shaped clamp 201 fits tightly against the HVAC pipe 3. At the same time, the locking screw 105 fits tightly against the outside of the upright 101. Then tighten the other locking screw 105. This completes the fixing of the concave horizontal arm 103 and also completes the limiting clamping operation of the HVAC pipe 3.

[0038] By combining the above-mentioned components, not only can HVAC pipes 3 at different installation heights be supported, but also the operation steps are reduced, which can effectively improve the installation efficiency.

[0039] Please refer to this carefully. Figures 1-3 The locking screw 105 is located on the outer side of the part between the concave horizontal arm 103 and the arc-shaped clamp 201, and is threaded with a reinforcing nut 106. The reinforcing nut 106 fits against the side of the vertical part of the concave horizontal arm 103 to lock and reinforce the position of the locking screw 105.

[0040] In this embodiment: after the locking screw 105 is tightened, the reinforcing nut 106 is turned so that it moves closer to the side of the concave cross arm 103. Finally, the reinforcing nut 106 is tightly fitted to the side of the concave cross arm 103. At this time, the position of the locking screw 105 is locked, which further improves the structural stability of the bracket.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
