Description

Technical Field

[0001] This utility model relates to the field of fixed support technology, specifically a fixed support for HVAC pipe installation. Background Technology

[0002] HVAC is a category of building equipment, mainly including heating, ventilation, and air conditioning. HVAC pipes are pipes used for gas exchange. HVAC pipes are usually classified into three types according to their uses: plastic pipes, metal pipes, and composite pipes. In order to facilitate the flow of fresh air, HVAC pipes are usually laid in the ceiling of the room. Users need a kind of fixed bracket for HVAC pipe installation to reduce the difficulty of HVAC pipe installation.

[0003] A search revealed a patent publication number CN221390792U for a fixing bracket for installing HVAC pipes, which includes a base. Four pulleys are fixedly connected to the lower end of the base. Telescopic columns are fixedly connected to the upper left and upper right parts of the base. A cylinder and a lubrication device are fixedly connected to the middle of the upper end of the base. The lubrication device is located to the left of the cylinder. A control device is fixedly connected to the output end of the cylinder and the upper ends of the two telescopic columns. A clamping device is threaded onto the outer surface of the control device.

[0004] The aforementioned patent documents describe a method where a clamping device is used to place the HVAC pipe between arc-shaped limiting plates. A rotary motor drives a lead screw to rotate, causing two No. 1 lassos to move to the left and right, thereby clamping and fixing the HVAC pipe within the arc-shaped limiting plates. However, in practical use, this device relies on motor operation, which is not environmentally friendly. Furthermore, it can only be used temporarily, and because the orientation of the limiting plates is fixed, it is difficult to change the orientation of the pipe after installation. Reinstallation requires disassembling the clamping device, which is time-consuming and labor-intensive. Therefore, there is an urgent need for a fixing bracket for HVAC pipe installation. Utility Model Content

[0005] The purpose of this utility model is to provide a fixing bracket for HVAC pipe installation, so as to solve the problems mentioned in the background art that the existing fixing brackets are inconvenient to change the orientation of the pipes and have poor environmental performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixing bracket for HVAC pipe installation, comprising a base and a rotating disk rotatably mounted on the upper end face of the base via a rotating shaft. A bracket sleeve is rotatably mounted on the upper end face of the rotating disk. A bracket rod is threaded into the inner cavity of the bracket sleeve. A clamping sleeve is fixedly mounted on the upper end face of the bracket rod. A limiting plate is slidably mounted on the inner side wall of the clamping sleeve. An opening is provided at the upper part of the clamping sleeve. There are two limiting plates, which are respectively located on both sides of the opening. A locking mechanism for fixing the rotating disk is provided on the upper end face of the base near the rotating disk. A lifting mechanism for rotating the clamping sleeve is provided on the upper end face of the rotating disk.

[0007] Preferably, the inner sidewall of the clamping sleeve is provided with grooves on both sides of the opening, a slider is slidably installed in the inner cavity of the groove, and a return spring is fixedly installed on the sidewall of the slider.

[0008] Preferably, the end of the reset spring away from the slider is fixedly installed on the inner wall of the slide groove, the slider is fixedly connected to the limiting plate, and one side of the two limiting plates at opposite positions is set as an arc surface.

[0009] Preferably, the locking mechanism includes a support column fixedly installed on the end face of the base, and a top plate fixedly installed on the end face of the support column. A limit post is slidably installed on the end of the top plate away from the support column. An end plate is fixedly installed on the end of the limit post, and a locking spring is fixedly installed on the inner wall of the end plate.

[0010] Preferably, the other end of the locking spring is fixedly installed on the end face of the top plate, the rotating disk has a limiting hole corresponding to the cross-section of the limiting post, the number of the limiting holes is 4, the upper end face of the base has mounting holes around the perimeter, and the lower end face of the base is fixedly installed with an adhesive sticker.

[0011] Preferably, the lifting mechanism includes a vertical plate fixedly installed on the left side of the upper end face of the rotating disk, and a worm gear rotatably installed between the vertical plates. A handle is fixedly installed at the end of the worm gear, and a worm wheel is fixedly installed in the middle of the side wall of the support sleeve. The worm gear and the worm wheel are meshed together.

[0012] Preferably, limit sleeves are fixedly installed on both the left and right sides of the upper end face of the rotating disk, and limit rods are slidably installed in the inner cavity of the limit sleeves. The limit rods are fixedly installed on the lower part of the outer side wall of the clamping sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, workers can quickly install the entire device on the ground or wall using fasteners and mounting holes or adhesive tape. The HVAC pipes can be pressed against the limiting plates via the arc surfaces on both sides. The inner wall of the clamping sleeve has grooves on both sides of the opening. The HVAC pipes can then press against the limiting plates, causing the slider to slide within the grooves, compressing the return spring. Once the HVAC pipes are fully inside the clamping sleeve, the return spring resets, and the limiting plates on both sides return to the center of the clamping sleeve. At this point, the entire device can secure the HVAC pipes.

[0015] 2. In this utility model, the operator can lift the end plate to change the orientation of the clamping sleeve mounted on the rotating disk via the bracket. After the orientation of the clamping sleeve changes, the end plate is released, and the locking spring is reset. This allows the end plate to move the limiting post downwards, and the limiting post will engage with the limiting hole on the rotating disk, thus keeping the clamping sleeve on the rotating disk fixed. As described above, this bracket can change the orientation of the clamping sleeve after it is fixed, making it suitable for supporting and fixing HVAC pipes with different orientations. This avoids repeated disassembly and installation of the entire bracket, preventing cracks and damage to the ground or wall, and improving the environmental protection and practicality of the entire device.

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a technical solution for a fixed bracket for HVAC pipe installation: a fixed bracket for HVAC pipe installation includes a base 1 and a rotating disk 2 rotatably mounted on the middle of the upper end face of the base 1 via a rotating shaft. A bracket sleeve 3 is rotatably mounted on the upper end face of the rotating disk 2. A bracket rod 31 is threadedly mounted in the inner cavity of the bracket sleeve 3. A clamping sleeve 4 is fixedly mounted on the upper end face of the bracket rod 31. A limiting plate 5 is slidably mounted on the inner side wall of the clamping sleeve 4. An opening is provided at the upper part of the clamping sleeve 4. There are two limiting plates 5, which are respectively located on both sides of the opening. A locking mechanism 6 for fixing the rotating disk 2 is provided on the upper end face of the base 1 near the rotating disk 2. A lifting mechanism 7 for rotating the clamping sleeve 4 is provided on the upper end face of the rotating disk 2.

[0023] Furthermore, the inner sidewall of the clamping sleeve 4 is provided with a sliding groove 41 on both sides of the opening, and a slider 42 is slidably installed in the inner cavity of the sliding groove 41. A return spring 43 is fixedly installed on the sidewall of the slider 42.

[0024] The end of the reset spring 43 away from the slider 42 is fixedly installed on the inner wall of the slide groove 41. The slider 42 is fixedly connected to the limiting plate 5. One side of the two limiting plates 5 at opposite positions is set as an arc surface.

[0025] It should be noted that, through the arc surfaces opened on the limiting plates 5 on both sides, the operator can press the HVAC pipe against the limiting plates 5. The inner side wall of the clamping sleeve 4 is provided with sliding grooves 41 on both sides of the opening. At this time, the HVAC pipe can squeeze the limiting plates 5 to make the slider 42 slide in the sliding grooves 41, which compresses the return spring 43 until the HVAC pipe is completely inserted into the inner cavity of the clamping sleeve 4. Then the return spring 43 is reset, and the limiting plates 5 on both sides return to the middle of the clamping sleeve 4. At this time, the entire device can complete the function of fixing the HVAC pipe.

[0026] Furthermore, the locking mechanism 6 includes a support column 61 fixedly installed on the end face of the base 1, and a top plate 62 fixedly installed on the end face of the support column 61. A limit post 63 is slidably installed on the end of the top plate 62 away from the support column 61. An end plate 64 is fixedly installed on the end of the limit post 63, and a locking spring 65 is fixedly installed on the inner wall of the end plate 64.

[0027] The other end of the locking spring 65 is fixedly installed on the end face of the top plate 62. The rotating disk 2 is provided with a limiting hole 21 corresponding to the cross section of the limiting post 63. There are 4 limiting holes 21. The upper end face of the base 1 is provided with mounting holes 11 around the perimeter. The lower end face of the base 1 is fixedly installed with an adhesive sticker 12.

[0028] It should be noted that by pulling up the end plate 64, the orientation of the clamping sleeve 4, which is mounted on the rotating disk 2 via the bracket 3, can be changed. After the orientation of the clamping sleeve 4 is changed, the end plate 64 is released, and the locking spring 65 is reset. This allows the end plate 64 to move the limiting post 63 downward, and the limiting post 63 will engage in the limiting hole 21 on the rotating disk 2. In other words, the clamping sleeve 4 on the rotating disk 2 will remain fixed. Thus, as described above, this bracket can change the orientation of the clamping sleeve 4 after it is fixed, making it suitable for supporting and fixing HVAC pipes with different orientations. This avoids repeated disassembly and installation of the entire bracket, which could cause cracks and damage to the ground or wall, and improves the environmental protection and practicality of the entire device.

[0029] Furthermore, the lifting mechanism 7 includes a vertical plate 71 fixedly installed on the left side of the upper end face of the rotating disk 2, and a worm gear 72 rotatably installed between the vertical plates 71. A handle 73 is fixedly installed at the end of the worm gear 72, and a worm wheel 74 is fixedly installed in the middle of the side wall of the bracket sleeve 3. The worm gear 72 and the worm wheel 74 are meshed and connected.

[0030] Limiting sleeves 75 are fixedly installed on both the left and right sides of the upper end face of the rotating disk 2. Limiting rods 76 are slidably installed in the inner cavity of the limiting sleeves 75. The limiting rods 76 are fixedly installed on the lower part of the outer side wall of the clamping sleeve 4.

[0031] It should be noted that by rotating the handle 73, the worm 72 can be rotated. Since the worm 72 is meshed with the worm wheel 74, when the worm 72 rotates, the worm wheel 74 will drive the bracket sleeve 3 to rotate together. Through the threaded connection between the bracket sleeve 3 and the bracket rod 31, under the constraint of the limiting sleeves 75 on the left and right sides on the limiting rod 76, the bracket rod 31 will retract towards the inside of the bracket sleeve 3 or extend towards the outside of the bracket sleeve 3, so that the height of the clamping sleeve 4 changes, so as to be suitable for HVAC pipes of different heights, further improving the practicality of the entire bracket.

[0032] Working principle:

[0033] After the staff can quickly install the entire device on the ground or wall by using fasteners and mounting holes 11 or adhesive tape 12, the staff can press the HVAC pipe against the limit plate 5 through the arc surface on the limit plate 5 on both sides. The inner wall of the clamping sleeve 4 is provided with sliding grooves 41 on both sides of the opening. At this time, the HVAC pipe can squeeze the limit plate 5 to make the slider 42 slide in the sliding groove 41, which compresses the return spring 43 until the HVAC pipe is completely inserted into the inner cavity of the clamping sleeve 4. Then the return spring 43 is reset, and the limit plates 5 on both sides return to the middle of the clamping sleeve 4. At this time, the entire device can complete the function of fixing the HVAC pipe.

[0034] Since the rotating disk 2 is mounted on the base 1 via a rotating shaft, when the operator pulls up the end plate 64, the orientation of the clamping sleeve 4 mounted on the rotating disk 2 via the bracket 3 can be changed. After the orientation of the clamping sleeve 4 is changed, the end plate 64 is released, and the locking spring 65 is reset. This allows the end plate 64 to move the limiting post 63 downward. The limiting post 63 will engage in the limiting hole 21 on the rotating disk 2, thus keeping the clamping sleeve 4 on the rotating disk 2 fixed. As described above, this bracket can change the orientation of the clamping sleeve 4 after it is fixed, making it suitable for supporting and fixing HVAC pipes with different orientations. This avoids repeated disassembly and installation of the entire bracket, which could cause cracks and damage to the ground or wall, and improves the environmental protection and practicality of the entire device.

[0035] By rotating the handle 73, the operator can rotate the worm 72. Since the worm 72 is meshed with the worm wheel 74, when the worm 72 rotates, the worm wheel 74 will drive the bracket sleeve 3 to rotate as well. Through the threaded connection between the bracket sleeve 3 and the bracket rod 31, under the constraint of the limiting sleeves 75 on the left and right sides on the limiting rod 76, the bracket rod 31 will retract towards the inside of the bracket sleeve 3 or extend towards the outside of the bracket sleeve 3, thereby changing the height of the clamping sleeve 4 to suit HVAC pipes of different heights, further improving the practicality of the entire bracket.

[0036] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
