Description

Technical Field

[0001] This utility model relates to the field of HVAC pipe connection technology, and specifically to an HVAC pipe connection component. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) ducts are widely used in various types of buildings, such as residential buildings, commercial buildings, and industrial plants. In residential buildings, HVAC ducts are mainly used for heating and hot water supply; in commercial buildings, they are mainly used for air conditioning, ventilation, and lighting; and in industrial plants, they are mainly used for heating, cooling, and ventilation during the production process.

[0003] Currently, during the connection process of HVAC pipes, workers often support the pipes and then weld the gaps. However, in high-altitude environments such as suspended ceilings or scaffolding, workers can only support the pipes with one hand to stabilize them and weld with the other. Supporting with one hand is insufficient to counteract the weight of the pipes and welding vibrations, which can easily lead to pipe misalignment and affect the welding quality. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A heating, ventilation, and air conditioning (HVAC) pipe connection assembly, comprising:

[0006] The tabletop has a bubble level connected to the top center and U-shaped brackets connected to the top two sides of the tabletop, with clamping mechanisms on both sides of the U-shaped brackets.

[0007] The bottom of the platform is connected to two pairs of first hinge seats. A support frame is rotatably connected inside each pair of first hinge seats. Seven connecting rods are connected from top to bottom on the inner side of the support frame. A second sleeve is slidably connected to the outer side of the support frame. A first positioning mechanism is provided at the top of the second sleeve. A pair of second hinge seats are rotatably connected to the bottom of the second sleeve. A base is connected to the bottom of the second hinge seats.

[0008] A second positioning mechanism is provided on the outer side of the pair of connecting rods.

[0009] In one possible implementation, the clamping mechanism includes screw holes on both sides of the U-shaped bracket, with a screw threaded inside the screw holes. One end of the screw is rotatably connected to a bearing seat, and a clamping plate is connected to the outside of the bearing seat. The other end of the screw is connected to a knob.

[0010] In one possible implementation, the bottom surface of the inner wall of the U-shaped bracket is connected to a support seat.

[0011] In one possible implementation, the outer walls of both the clamp and the support are set to an arc shape.

[0012] In one possible implementation, the first positioning mechanism includes a pair of second positioning holes on both sides of the second sleeve, and a first bolt connection is connected through the interior of the pair of second positioning holes. The support frame has six pairs of first positioning holes from top to bottom on both sides, and the first bolt connection passes through the interior of the first positioning holes.

[0013] In one possible implementation, the seven connecting rods and the six pairs of the first positioning holes are staggered.

[0014] In one possible implementation, the second positioning mechanism includes a positioning plate with seven fourth positioning holes on both sides. A pair of first sleeves are slidably connected to the outer side of the positioning plate. One end of the first sleeve is rotatably connected to a connecting rod. A pair of third positioning holes are provided on both adjacent sides of the pair of first sleeves. A second bolt connection pair is connected through the interior of the pair of third positioning holes. The second bolt connection pair passes through the interior of the third positioning holes.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By moving the U-shaped bracket to a position below the HVAC pipe interface, and then removing the first bolt connection pair, the height of the U-shaped bracket can be easily adjusted until the support is raised to the bottom of the HVAC pipe interface. After locking the height with the first bolt connection pair, the U-shaped bracket directly bears the vertical load of the pipe, avoiding hand fatigue. Then, by rotating the knobs on both sides, the cooperation between the screw, screw hole, and bearing seat facilitates the movement of the clamps on both sides towards each other, clamping the HVAC pipe and counteracting the lateral displacement tendency during welding, thereby preventing pipe misalignment and improving the stability of the welding process.

[0017] 2. By setting a pair of first sleeves and a sliding positioning plate on the inner side of the first sleeves, the two sides of the positioning plate are fixedly connected to the first sleeves by a pair of second bolts. The pair of first sleeves are rotatably connected to the connecting rods on both sides, which helps to improve the stability of the support frame on both sides during use and further improves the stability during the welding process.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This application provides a heating, ventilation, and air conditioning (HVAC) pipe connection assembly to solve the problems in the prior art.

[0027] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0028] like Figures 1-4 As shown, a heating, ventilation, and air conditioning (HVAC) pipe connection assembly includes:

[0029] The tabletop 3 has a bubble level 4 connected to the top center. U-shaped brackets 1 are connected to the top two sides of the tabletop 3. Clamping mechanisms are provided on both sides of the U-shaped brackets 1. By setting the bubble level 4, it is easy for staff to clearly understand whether the tabletop 3 is in a horizontal position.

[0030] The bottom of the tabletop 3 is connected to two pairs of first hinge seats 22. A support frame 9 is rotatably connected inside the pair of first hinge seats 22. Seven connecting rods 13 are connected from top to bottom on the inner side of the support frame 9. A second sleeve 11 is slidably connected to the outer side of the support frame 9. A first positioning mechanism is provided at the top of the second sleeve 11. A pair of second hinge seats 23 are rotatably connected to the bottom of the second sleeve 11. A base 12 is connected to the bottom of the second hinge seats 23.

[0031] A second positioning mechanism is provided on the outer side of a pair of connecting rods 13.

[0032] In some examples, the clamping mechanism includes screw holes 20 on both sides of the U-shaped bracket 1. A screw 19 is threaded inside the screw hole 20. One end of the screw 19 is rotatably connected to a bearing seat 21. A clamping plate 7 is connected to the outside of the bearing seat 21. The other end of the screw 19 is connected to a knob 2. Rotating the knobs 2 on both sides facilitates the movement of the clamping plates 7 on both sides towards each other through the cooperation between the screw 19, the screw hole 20, and the bearing seat 21, thereby clamping the HVAC pipe.

[0033] In some examples, the bottom surface of the inner wall of the U-shaped bracket 1 is connected to a support seat 8.

[0034] In some examples, the outer walls of both the clamp 7 and the support 8 are designed to be curved to increase the contact area with the HVAC pipes.

[0035] In some examples, the first positioning mechanism includes a pair of second positioning holes 15 on both sides of the second sleeve 11. A first bolt connection 10 is connected through the interior of the pair of second positioning holes 15. Six pairs of first positioning holes 14 are opened from top to bottom on both sides of the support frame 9. The first bolt connection 10 passes through the interior of the first positioning holes 14. The first bolt connection 10 can be removed to facilitate the adjustment of the distance between the support frame 9 and the second sleeve 11, and thus facilitate the adjustment of the height of the U-shaped bracket 1 until the support seat 8 is raised to the bottom position of the HVAC pipe interface. After locking the height by the first bolt connection 10, the U-shaped bracket 1 directly bears the vertical load of the pipe.

[0036] In some examples, the seven connecting rods 13 and the six pairs of first positioning holes 14 are staggered.

[0037] In some examples, the second positioning mechanism includes a positioning plate 6, with seven fourth positioning holes 18 corresponding to both sides of the positioning plate 6. A pair of first sleeves 5 are slidably connected to the outer side of the positioning plate 6. One end of the first sleeve 5 is rotatably connected to the connecting rod 13. A pair of third positioning holes 16 are provided on both adjacent sides of the pair of first sleeves 5. A second bolt connection pair 17 is connected through the inside of the pair of third positioning holes 16. The second bolt connection pair 17 passes through the inside of the third positioning holes 16. By adjusting the distance between the pair of first sleeves 5 and the positioning plate 6, it is convenient to adapt to the unfolding angle of the support frame 9 on both sides, so as to achieve the effect of stabilizing the support frame 9.

[0038] This invention moves the U-shaped bracket 1 to a position below the HVAC pipe interface, then removes the first bolt connection 10 to facilitate height adjustment of the U-shaped bracket 1 until the support base 8 is raised to the bottom of the HVAC pipe interface. After locking the height with the first bolt connection 10, the U-shaped bracket 1 directly bears the vertical load of the pipe, avoiding hand fatigue. Then, rotating the knobs 2 on both sides, through the cooperation between the screw 19, screw hole 20, and bearing seat 21, facilitates the movement of the clamping plates 7 on both sides towards each other, clamping the HVAC pipe and counteracting the lateral displacement tendency during welding, thereby preventing pipe misalignment and improving stability during the welding process. Secondly, by setting a pair of first sleeves 5 and a sliding positioning plate 6 on the inner side of the first sleeves 5, the two sides of the positioning plate 6 are fixedly connected to the first sleeves 5 by a pair of second bolt connection 17. The pair of first sleeves 5 are rotatably connected to the connecting rods 13 on both sides, which helps to improve the stability of the support frames 9 on both sides during use, further improving the stability during the welding process.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
