[0024] Example: See Figure 1 , Figure 2 and Figure 3 , an angled HVAC pipe mounting bracket, comprising a base 4, a lifting mechanism 1 and a clamping mechanism 2, wherein the lifting mechanism 1 is mounted on the base 4 and supports the clamping mechanism 2 for lifting, and the clamping mechanism 2 is mounted to clamp the HVAC pipe, and the lifting mechanism 1 comprises a plurality of lifting rods 12 and a lifting plate 11, wherein the upper ends of the lifting rods 12 are evenly distributed and connected to the lower surface of the lifting plate 11 through hinges 13, and the lower ends of the lifting rods 12 are mounted on the base 4 through hinged sliding parts; the clamping mechanism 2 comprises a horizontally placed cylindrical sleeve 21, wherein two symmetrically arranged arc-shaped clamping plates 22 are arranged in the sleeve 21, and the two clamping plates 22 are movably mounted on both sides of the sleeve 21 through threaded screws 23; the two ends of the bottom of the sleeve 21 are mounted on the lifting plate 11 through an angle adjustment mechanism 3 with adjustable inclination angle.

[0025] The angle adjustment mechanism 3 is composed of two symmetrically arranged parts, each of which includes a threaded adjustment rod 31, an adjustment knob 32 and a ball hinge. The threaded adjustment rod 31 is vertically installed on the lifting plate 11 through a thread. The top end of the threaded adjustment rod 31 is connected to the ball hinge at the bottom of the sleeve 21, and the bottom end is fixedly connected to the adjustment knob 32. The two ball hinges are respectively located at the two ends of the bottom of the sleeve 21. The ball hinge is a groove hinge, including a limit groove 33 fixedly installed at the bottom of the sleeve 21. The limit groove 33 has a horizontally placed hollow cylindrical structure inside, and a strip opening is opened at the bottom for the upper end of the threaded adjustment rod 31 to move horizontally. The top end of the threaded adjustment rod 31 is a ball 34 embedded in the limit groove 33.

[0026] When the angle needs to be adjusted to raise one end, the threaded adjustment rod 31 is driven to rotate on the lifting plate 11 by rotating the adjustment knob 32 at the corresponding end, so that the height of the threaded adjustment rod 31 is increased, and the ball 34 at the top supports the limit groove 33, thereby lifting the sleeve 21 on that side and causing the sleeve 21 to tilt at an angle. When the angle needs to be increased, the adjustment knob 32 on the other side can be adjusted at the same time to lower the threaded adjustment rod 31 on that side, and the angle is increased by the increase and decrease of the two. At this time, the threaded adjustment rod 31 also has a certain inclination relative to the limit groove 33, and the threaded adjustment rod 31 can slide along the strip opening to a certain extent, and the ball 34 also moves to a certain extent in the limit groove 33.

[0027] The sliding component includes several parallel sliding grooves 19 opened on the base 4, and a baffle 6 protruding from the base 4 is provided on the base at both ends of each sliding groove 19. A bidirectional threaded rod 14 is rotatably connected between the two baffles 6. The bidirectional threaded rod 14 is symmetrically provided with two sliders 15 controlled by the bidirectional threaded rod 14 to slide horizontally. The lower end of the slider 15 is slidably set in the sliding groove 19, and the middle part is sleeved on the bidirectional threaded rod 14. The upper hinge 13 is connected to a lifting rod 12.

[0028] A bearing 7 is provided on the baffle 6, and the two ends of the bidirectional threaded rod 14 are rotatably connected to the baffle 6 through the bearing 7. The bidirectional threaded rod 14 is two parallel rods, and the same end of the two bidirectional threaded rods 14 is connected and rotated synchronously through a driving component. The driving component is a servo motor 16 installed on the base 4. The output end of the servo motor 16 and the end of the bidirectional threaded rod 14 are both provided with pulleys 17, and each pulley 17 is connected and rotated through a synchronous belt 18. A bearing 7 is provided on each baffle 6, and the two ends of the bidirectional threaded rod 14 are fixed by the bearing 7, thereby limiting the axial and radial positions of the bidirectional threaded rod 14, and only rotational movement can be performed.

[0029] When installing the HVAC pipe, first install the HVAC pipe between the clamping plates 22 of the sleeve 21, and then use the rotary valve 24 to rotate the threaded screw 23 to allow the clamping plates 22 to clamp and fix the HVAC pipe. Then adjust the angle of the sleeve 21 through the angle adjustment mechanism 3 as needed, and then lift the lifting plate 11 to adjust the height. The left and right sections of the bidirectional threaded rod 14 have opposite thread directions, and the middle of the slider 15 set on each section has an internal thread hole that matches the section of the bidirectional threaded rod 14, and the lower part of the slider 15 matches the shape of the slide 19.

[0030] The servo motor 16 is started to rotate forward or reversely. The output end of the servo motor 16 drives the two pulleys 17 to rotate through the synchronous belt 18. The two pulleys 17 respectively drive the two bidirectional threaded rods 14 to rotate. The slider 15 on each bidirectional threaded rod 14 is driven by the rotation of the thread and moves toward or in the opposite direction along the slide 19. When moving toward each other, the hinge 13 on the slider 15 drives the angle between the lifting rod 12 and the base 4 to increase, thereby pushing the lifting plate 11 to rise. When moving in the opposite direction, the hinge 13 on the slider 15 drives the angle between the lifting rod 12 and the base 4 to decrease, thereby pushing the lifting plate 11 to descend.

[0031] There are two slide slots 19 and two-way threaded rods 14, and they correspond one to one. The two-way threaded rods 14 are located directly above the slide slots 19. There are four sliders 15 on the two slide slots 19, and each slider 15 is provided with a corresponding lifting rod 12. Four hinges 13 are distributed in a rectangular shape on the lower surface of the lifting plate 11, and every two hinges 13 form a row. Each hinge 13 is connected to a lifting rod 12, and the lower end of the lifting rod 12 is connected to a slider 15. The four lifting rods 12 work synchronously and support the lifting plate 11 together, so that the structure is more stable and not easy to deflect or tip over.

[0032] The clamping plate 22 is a rubber arc plate with elasticity, and the middle part of the outer side thereof is fixedly connected to the top of the threaded screw 23. The sleeve 21 is provided with a screw hole matching the threaded screw 23. The middle part of the threaded screw 23 is installed on the sleeve 21, and the end is fixedly connected to a rotary valve 24. The clamping plate 22 is a rubber arc plate with elasticity, which can fit and adapt to HVAC pipes of different sizes, and is more convenient to clamp and fix.

[0033] The lifting plate 11 is lifted and lowered by the lifting mechanism 1 on the base 4, and the lifting plate 11 drives the clamping mechanism 2 to lift and lower synchronously. The height can be adjusted at will according to needs. The clamping mechanism 2 clamps and fixes the HVAC pipe to facilitate the installation of the HVAC pipe. When it is necessary to install a HVAC pipe with an inclined angle, the angle adjustment mechanism 3 can be used to adjust the angle of the sleeve 21 relative to the lifting plate 11.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
