Description

Technical Field

[0001] This utility model relates to the field of HVAC duct installation technology, and in particular to an HVAC duct installation structure with adjustable support spacing. Background Technology

[0002] In order to improve the overall stability of HVAC ducts during use, they need to be positioned and installed.

[0003] A search of Chinese patent CN221075560U reveals a positioning and installation structure for HVAC ducts, including a connecting plate. A positioning seat is fixedly connected to the front of the connecting plate. A positioning groove is formed on the front of the positioning seat. An iron sheet is fixedly connected to the inner wall of the positioning groove. A positioning block is movably connected to the inner wall of the positioning groove. A magnet is fixedly connected to the back of the positioning block. A fixing plate is fixedly connected to the front of the positioning block.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] During the installation of existing HVAC ducts, most adjustable support clamps cannot simultaneously lock the ducts, requiring workers to lock each clamp individually, which is time-consuming, labor-intensive, cumbersome, and inconvenient. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes an adjustable support spacing HVAC pipe installation structure. The rotating fixed sleeve drives the rotating rod to rotate, the rotating rod drives three worm gears to rotate simultaneously, the worm gears drive the worm wheel and threaded rod to rotate, and the threaded rod drives the sliding frame and upper clamping plate to move downward, so that the upper clamping plate and lower clamping plate move closer to each other to clamp and fix the pipe. This allows multiple upper and lower clamping plates to clamp and fix the pipe simultaneously, thus facilitating the fixation of the pipe.

[0007] The technical solution to achieve the purpose of this utility model is: an adjustable support spacing HVAC pipe installation structure, including a base plate, a slide rail fixedly connected to the top of the base plate, three sliding seats slidably connected on the slide rail, and a support block fixedly connected to the top of each of the three sliding seats, and also including;

[0008] A clamping mechanism, which is located on a support block;

[0009] An adjustment mechanism, which is located on a sliding seat;

[0010] The clamping mechanism includes lower clamping plates fixedly connected to the top of three support blocks, sliding frames slidably connected to each of the three support blocks, upper clamping plates fixedly connected to each of the three sliding frames, threaded rods rotatably connected to each of the three support blocks, worm gears fixedly sleeved on each of the three threaded rods, worms rotatably connected to each of the three support blocks, and three worms meshing with three worm gears respectively. Fixed blocks are fixedly connected to both ends of the top of the slide rail, and rotating rods are rotatably connected to two of the fixed blocks. All three worms are slidably connected to the rotating rods.

[0011] In some embodiments, a set of limiting strips is fixedly connected to each of the three support blocks, and the three sliding frames are slidably connected to the three sets of limiting strips respectively.

[0012] In some embodiments, a rib is fixedly connected to the rotating rod, and the three worm gears are slidably sleeved on the rib.

[0013] In some embodiments, both ends of the rotating rod are fixedly fitted with fixed sleeves, which are made of rubber.

[0014] In some embodiments, the adjustment mechanism includes L-shaped blocks fixedly connected to three sliding seats, each of the three L-shaped blocks having a pin slidably connected to it, and each slide rail having three sets of slots, with one end of each of the three pins extending into the three sets of slots.

[0015] In some embodiments, a return spring is fitted onto each of the three pins, and the two ends of the return spring are fixedly connected to the pin and the L-shaped block, respectively.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] Firstly, this utility model, through the setting of a clamping mechanism, rotates the fixed sleeve to drive the rotating rod to rotate, the rotating rod to drive the three worm gears to rotate simultaneously, the worm gears to drive the worm wheel and the threaded rod to rotate, and the threaded rod to drive the sliding frame and the upper clamping plate to move downward, so that the upper clamping plate and the lower clamping plate move closer to each other to clamp and fix the pipe, so that multiple upper clamping plates and lower clamping plates can clamp and fix the pipe simultaneously, thereby facilitating the fixation of the pipe;

[0018] Secondly, this utility model, through the setting of the adjustment mechanism, pulls the pin outward to move it out of the slot. The movement of the pin causes the return spring to stretch and undergo elastic deformation. Then, the sliding seat moves to move the support block. The movement of the support block causes the lower clamp, sliding frame and upper clamp to move until the sliding seat moves to the required position. The pin is then released, so that the return spring drives the pin into the slot, thereby realizing the adjustment of the spacing of the support clamp.

[0019] This solves the problem that most existing adjustable support clamps cannot simultaneously lock HVAC ducts. Attached Figure Description

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an adjustable support spacing HVAC duct installation structure through improvements. The technical solution of this utility model is as follows:

[0028] like Figures 1-3As shown, an adjustable support spacing HVAC duct installation structure includes a base plate 1, a slide rail 11 fixedly connected to the top of the base plate 1, three sliding seats 12 slidably connected to the slide rail 11, and a support block 13 fixedly connected to the top of each of the three sliding seats 12. It also includes a clamping mechanism located on the support blocks 13; and an adjustment mechanism located on the sliding seats 12. The clamping mechanism includes lower clamping plates 14 fixedly connected to the tops of the three support blocks 13, sliding frames 15 slidably connected to each of the three support blocks 13, upper clamping plates 16 fixedly connected to each of the three sliding frames 15, threaded rods 24 rotatably connected to each of the three support blocks 13, worm gears 23 fixedly sleeved on each of the three threaded rods 24, and worm gears 23 rotatably connected to each of the three support blocks 13. The three worm gears 22 are meshed with the three worm wheels 23 respectively. The top two ends of the slide rail 11 are fixedly connected to the fixing blocks 2. The two fixing blocks 2 are rotatably connected to the rotating rod 21. The three worm gears 22 are slidably connected to the rotating rod 21. Through the setting of the clamping mechanism, the rotating fixing sleeve 27 drives the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the three worm gears 22 to rotate at the same time. The rotation of the worm gears 22 drives the worm wheels 23 and the threaded rod 24 to rotate. The rotation of the threaded rod 24 drives the sliding frame 15 and the upper clamping plate 16 to move downward, so that the upper clamping plate 16 and the lower clamping plate 14 move closer to each other to clamp and fix the pipe. This allows multiple upper clamping plates 16 and lower clamping plates 14 to clamp and fix the pipe at the same time, which facilitates the fixation of the pipe.

[0029] like Figure 2 As shown, in one embodiment, a set of limiting strips 25 are fixedly connected to each of the three support blocks 13, and the three sliding frames 15 are slidably connected to the three sets of limiting strips 25 respectively; the setting of the limiting strips 25 enables the sliding frames 15 to be guided.

[0030] like Figure 2 As shown, in one embodiment, a rib 26 is fixedly connected to the rotating rod 21, and three worm gears 22 are slidably sleeved on the rib 26. With the rib 26, the rotation of the rotating rod 21 can drive the worm gears 22 to rotate through the rib 26, so that the rotating rod 21 can drive the worm gears 22 to rotate while the worm gears 22 can still slide.

[0031] like Figure 3 As shown, in one embodiment, both ends of the rotating rod 21 are fixedly sleeved with fixed sleeves 27, which are made of rubber. The fixed sleeves 27 facilitate the rotation of the rotating rod 21.

[0032] like Figure 3As shown, in one embodiment, the adjustment mechanism includes L-shaped blocks 17 fixedly connected to three sliding seats 12 respectively. Each of the three L-shaped blocks 17 is slidably connected with a pin 18. Each slide rail 11 has three sets of slots 110. One end of each of the three pins 18 extends into the three sets of slots 110. Each of the three pins 18 is fitted with a return spring 19. The two ends of the return spring 19 are fixedly connected to the pin 18 and the L-shaped block 17 respectively. Through the setting of the pins 18, the spacing of the support clamp is adjusted by the cooperation of the pins 18 and the return springs 19.

[0033] The specific working method is as follows: Pull the pin 18 outward to move it out of the slot 110. The movement of the pin 18 causes the return spring 19 to stretch and undergo elastic deformation. Then, the sliding seat 12 moves to move the support block 13. The movement of the support block 13 causes the lower clamping plate 14, the sliding frame 15, and the upper clamping plate 16 to move until the sliding seat 12 moves to the required position. Release the pin 18 so that the return spring 19 drives the pin 18 into the slot 110, thereby adjusting the spacing of the support clamp. Rotate the fixed sleeve 27 to drive the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the three worm gears 22 to rotate simultaneously. The rotation of the worm gears 22 drives the worm wheel 23 and the threaded rod 24 to rotate. The rotation of the threaded rod 24 causes the sliding frame 15 and the upper clamping plate 16 to move downward, so that the upper clamping plate 16 and the lower clamping plate 14 move closer to each other to clamp and fix the pipe. This allows multiple upper clamping plates 16 and lower clamping plates 14 to clamp and fix the pipe simultaneously, thus facilitating the fixation of the pipe.

[0034] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
