Description

Technical Field

[0001] This application relates to the field of HVAC duct installation technology, and more specifically, to a fixed installation structure for HVAC ducts. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) ducts are piping systems in buildings used to transfer heat or cool air. Generally made of metal or plastic, these ducts are commonly used in heating, ventilation, and air conditioning systems, playing a vital role in regulating indoor temperature and air quality.

[0003] A search revealed that patent CN222363499U discloses an installation structure for HVAC pipes. This patent uses a fixing clamp and a support plate. By rotating the support plate toward the fixing clamp, the clamping teeth engage with the ratchet groove, thereby fixing the HVAC pipes.

[0004] While the aforementioned patent achieves the fixation of HVAC pipes of different diameters, it relies solely on the engagement of locking teeth with the ratchet groove of the upper clamp and the tension spring to provide clamping force for pipe fixation. Over time, the tension spring is prone to elastic fatigue and loosening, causing the locking teeth and ratchet groove to loosen. Especially when the pipe vibrates due to the flow of the medium, the locking teeth can easily slip out of the ratchet groove, causing the upper clamp to open, the pipe to lose its fixation, and thus leading to increased pipe shaking, collision damage with surrounding components, or even pipe displacement and detachment, thereby affecting the normal function of the HVAC system. Utility Model Content

[0005] To address the aforementioned issues, this application provides a fixed installation structure for HVAC ducts.

[0006] The technical solution for a fixed installation structure of HVAC ducts provided in this application is as follows:

[0007] A fixed installation structure for HVAC ducts includes a support frame and ducts located inside the support frame. The support frame has a placement plate inside, and one side of the placement plate has multiple sets of fixing components. Each set of fixing components includes multiple fixing blocks, a driving unit and a limiting unit. One side of each fixing block is arc-shaped.

[0008] Each drive unit includes a screw, and each screw is used to drive a corresponding fixed block to move, thereby pressing against the surface of the pipe.

[0009] Each limiting unit includes two locking bolts, and each fixed block has two second trapezoidal blocks inside. Each pair of locking bolts is used to drive the corresponding two second trapezoidal blocks to move, thereby limiting the fixed block.

[0010] Furthermore, each set of fixing components also includes an adjusting ring and two fixing ring frames. The two fixing ring frames are fixedly connected to both sides of the placement plate, and one end of each adjusting ring is rotatably connected to one side of one of the fixing ring frames.

[0011] Furthermore, a fixed housing is fixedly installed on one side of each fixed ring frame and adjusting ring. Each fixed abutment is located inside the corresponding fixed housing and is slidably connected. Each screw is threadedly connected to the corresponding fixed housing. One end of each screw is threaded through one side of the corresponding fixed housing and is rotatably connected to one side of the corresponding fixed abutment.

[0012] Furthermore, each fixed block has cavities on both sides inside, and each cavity has a limiting groove on its inner bottom wall. Each second trapezoidal block is located inside its corresponding cavity, and each second trapezoidal block has a limiting slider fixedly connected to its bottom. Each limiting slider is slidably connected to its corresponding limiting groove, and each limiting slider is fixedly connected to the inner wall of its corresponding cavity with a spring.

[0013] Furthermore, each cavity is provided with a first trapezoidal block inside, and one end of each locking bolt is threaded through one side of the corresponding fixed block and extends into the cavity. Each locking bolt is rotatably connected to one side of the corresponding first trapezoidal block.

[0014] Furthermore, each fixed housing has multiple limiting holes on both sides, and each second trapezoidal block extends through one side of the corresponding cavity to the outside of the corresponding fixed block. Each second trapezoidal block is inserted into the corresponding limiting hole.

[0015] The above technical solution allows the fixed block to move flexibly by being driven by the screw in the fixed component, thereby accurately adapting to HVAC pipes of different diameters. This eliminates the need to customize a fixed structure for pipes of different specifications, greatly improving the flexibility and versatility of use.

[0016] Furthermore, a fixing plate is fixedly connected to one end of each adjusting ring, a fixing block is provided on one side of each fixing plate, each fixing block is fixedly connected to one end of the corresponding fixing ring frame, and a fixing bolt is provided on one side of each fixing plate. Each fixing plate is fixedly connected to the corresponding fixing block by the corresponding fixing bolt.

[0017] Furthermore, the top of the support frame is provided with mounting bolts, and the number of mounting bolts is set to multiple.

[0018] The above technical solution avoids the adjusting ring from rotating or shifting under pipe vibration or external force, further ensuring the stability of the fixing component's circumferential clamping of the pipe.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] This invention utilizes a screw in the fixing assembly to drive the fixing block to move flexibly, thereby precisely adapting to HVAC pipes of different diameters. It eliminates the need for custom-designed fixing structures for different pipe specifications, significantly improving flexibility and versatility. The arc-shaped fixing block increases the contact area with the pipe, preventing localized damage while enhancing clamping force. Multiple fixing blocks from multiple fixing assemblies clamp the pipe from different directions, creating comprehensive restraint and preventing horizontal swaying. Furthermore, the mechanical locking structure, consisting of locking bolts, a first trapezoidal block, a second trapezoidal block, and a limiting socket, firmly positions the fixing block, effectively preventing displacement due to pipe vibration or external forces, further ensuring the fixing effect.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-6A fixed installation structure for HVAC pipes includes a support frame 1 and a pipe located inside the support frame 1. The support frame 1 is provided with a placement plate 2 inside. Multiple sets of fixing components are provided on one side of the placement plate 2. Each set of fixing components includes multiple fixing blocks 6, a driving unit and a limiting unit. One side of each fixing block 6 is arc-shaped.

[0030] Each drive unit includes a screw 7, and each screw 7 is used to drive the corresponding fixed block 6 to move, thereby pressing against the surface of the pipe.

[0031] Each limiting unit includes two locking bolts 15, and each fixed block 6 has two second trapezoidal blocks 10 inside. Each pair of locking bolts 15 is used to drive the corresponding two second trapezoidal blocks 10 to move, thereby limiting the fixed block 6.

[0032] Reference Figures 1-6 Each set of fixing components also includes an adjusting ring 4 and two fixing ring frames 3. The two fixing ring frames 3 are fixedly connected to both sides of the placement plate 2, respectively. One end of each adjusting ring 4 is rotatably connected to one side of one of the fixing ring frames 3. A fixing housing 5 is fixedly installed on one side of each fixing ring frame 3 and adjusting ring 4. Each fixing block 6 is located inside the corresponding fixing housing 5 and is slidably connected. Each screw 7 is threadedly connected to the corresponding fixing housing 5. One end of each screw 7 is threaded through one side of the corresponding fixing housing 5 and rotatably connected to one side of the corresponding fixing block 6. Cavities 14 are opened on both sides of the interior of each fixing block 6. A limit groove 11 is opened on the inner bottom wall of each cavity 14. Each second trapezoidal block 10 is located in the corresponding cavity 14. Inside, each second trapezoidal block 10 has a fixedly connected limit slider 12 at its bottom. Each limit slider 12 is slidably connected to a corresponding limit groove 11. Each limit slider 12 is fixedly connected to the inner wall of the corresponding cavity 14. Each cavity 14 has a first trapezoidal block 9 inside. One end of each locking bolt 15 is threaded through one side of the corresponding fixed block 6 and extends into the interior of the corresponding cavity 14. Each locking bolt 15 is rotatably connected to one side of the corresponding first trapezoidal block 9. Each fixed housing 5 has multiple limit holes 8 on both sides. Each second trapezoidal block 10 extends through one side of the corresponding cavity 14 and extends to the outside of the corresponding fixed block 6. Each second trapezoidal block 10 is inserted into the corresponding limit hole 8.

[0033] Multiple sets of fixing components can fix pipes of different diameters and ensure the stability of the fixing. The specific operation method is as follows: when fixing HVAC pipes of different diameters, first place the pipe on the placement plate 2 inside the support frame 1. The placement plate 2 can provide stable bottom support for the pipe, avoid the pipe from directly contacting the bottom of the support frame 1 and causing wear, and also provide a reference for the positioning of the subsequent fixing components.

[0034] Next, based on the actual diameter of the pipe, since one end of the adjusting ring 4 is rotatably connected to one of the fixed ring frames 3, the adjusting ring 4 is rotated until the fixed plate 16 and the fixed block 17 are in contact, and then fixed by the fixing bolt 18. At this time, the fixed ring frame 3 and the fixed housing 5 on one side of the adjusting ring 4 will be distributed around the pipe. The setting of the fixed housing 5 can not only provide sliding guide space for the internal fixed block 6, but also protect the drive unit and the limit unit from external collision damage.

[0035] Then, rotate the screw 7 on each fixed housing 5. Since the screw 7 is threadedly connected to the fixed housing 5 and one end of the screw 7 is rotatably connected to the fixed abutment 6, the rotation of the screw 7 will be converted into the linear movement of the fixed abutment 6 along the inside of the fixed housing 5 until the arc-shaped side of the fixed abutment 6 is tightly attached to the surface of the pipe. The arc design can increase the contact area between the fixed abutment 6 and the pipe, avoiding excessive local pressure that could damage the outer wall of the pipe. At the same time, the multiple fixed abutments 6 of the multiple fixed components can jointly clamp the pipe from different directions, forming an all-round clamping force to prevent the pipe from shaking in the horizontal direction.

[0036] After the fixed block 6 is positioned, the locking bolt 15 on the fixed block 6 is rotated using a tool. The locking bolt 15 pushes the first trapezoidal block 9, which is rotatably connected to its end, to move within the cavity 14. The inclined surface of the first trapezoidal block 9 presses against the second trapezoidal blocks 10 on both sides, causing the second trapezoidal blocks 10 to overcome the tension of the spring 13 and extend outward along the limiting groove 11. The cooperation between the limiting slider 12 and the limiting groove 11 ensures that the movement direction of the second trapezoidal block 10 is stable and avoids deviation. Finally, it is inserted into the corresponding limiting holes 8 on both sides of the fixed housing 5, thereby fixing HVAC pipes of different diameters.

[0037] The multiple limiting holes 8 on the fixed housing 5 can accommodate different moving distances of the fixed block 6, thereby meeting the position requirements of the fixed block 6 when fixing pipes of different diameters. The insertion and engagement of the second trapezoidal block 10 with the limiting holes 8 can firmly lock the fixed block 6 in its current position, preventing it from shifting due to pipe vibration or external force. Furthermore, the spring 13 can pull the second trapezoidal block 10 to reset during subsequent disassembly, facilitating the retraction and adjustment of the fixed block 6.

[0038] The screw 7 in the fixing assembly drives the fixing block 6 to move flexibly, thereby accurately adapting to HVAC pipes of different diameters. There is no need to customize the fixing structure for different pipe specifications, which greatly improves the flexibility and versatility of use. The arc-shaped fixing block 6 can increase the contact area with the pipe, avoid local pressure damage to the pipe and enhance the clamping force. Multiple fixing blocks 6 of multiple fixing assemblies can jointly clamp the pipe from different directions to form an all-round constraint and prevent the pipe from shaking horizontally. At the same time, the mechanical locking structure of the locking bolt 15, the first trapezoidal block 9, the second trapezoidal block 10 and the limiting socket 8 can firmly limit the fixing block 6, effectively preventing the fixing block 6 from shifting due to pipe vibration or external force, and further ensuring the fixing effect.

[0039] Reference Figures 1-5 Each adjusting ring 4 has a fixed plate 16 fixedly connected to one end, and a fixed block 17 is provided on one side of each fixed plate 16. Each fixed block 17 is fixedly connected to one end of the corresponding fixed ring frame 3. Each fixed plate 16 has a fixed bolt 18 on one side. Each fixed plate 16 is fixedly connected to the corresponding fixed block 17 by the corresponding fixed bolt 18. The top of the support frame 1 is provided with mounting bolts 19, and the number of mounting bolts 19 is set to multiple.

[0040] By setting the fixing plate 16, fixing block 17, and fixing bolt 18, after the adjusting ring 4 is rotated to an angle that matches the pipe diameter, the fixing plate 16 and fixing block 17 can be firmly locked by the fixing bolt 18, so that the adjusting ring 4 and the fixing ring frame 3 form a stable ring support structure, preventing the adjusting ring 4 from rotating and shifting under pipe vibration or external force, and further ensuring the stability of the fixing assembly in clamping the pipe.

[0041] The multiple mounting bolts 19 not only facilitate the secure installation of the entire support frame 1 in designated locations such as walls and ceilings, ensuring that the support frame 1 as a whole will not shift, but also distribute the force through the multiple mounting bolts 19, preventing a single bolt from loosening or being damaged due to concentrated force, thus providing a stable installation foundation for the pipeline.

[0042] Working principle: When fixing HVAC pipes of different diameters, the pipes are first placed on the placement plate 2 inside the support frame 1. The placement plate 2 can provide stable bottom support for the pipes, avoid the pipes from directly contacting the bottom of the support frame 1 and causing wear, and also provide a reference for the positioning of subsequent fixing components.

[0043] Next, based on the actual diameter of the pipe, since one end of the adjusting ring 4 is rotatably connected to one of the fixed ring frames 3, the adjusting ring 4 is rotated until the fixed plate 16 and the fixed block 17 are in contact, and then fixed by the fixing bolt 18. At this time, the fixed ring frame 3 and the fixed housing 5 on one side of the adjusting ring 4 will be distributed around the pipe. The setting of the fixed housing 5 can not only provide sliding guide space for the internal fixed block 6, but also protect the drive unit and the limit unit from external collision damage.

[0044] Then, rotate the screw 7 on each fixed housing 5. Since the screw 7 is threadedly connected to the fixed housing 5 and one end of the screw 7 is rotatably connected to the fixed abutment 6, the rotation of the screw 7 will be converted into the linear movement of the fixed abutment 6 along the inside of the fixed housing 5 until the arc-shaped side of the fixed abutment 6 is tightly attached to the surface of the pipe. The arc design can increase the contact area between the fixed abutment 6 and the pipe, avoiding excessive local pressure that could damage the outer wall of the pipe. At the same time, the multiple fixed abutments 6 of the multiple fixed components can jointly clamp the pipe from different directions, forming an all-round clamping force to prevent the pipe from shaking in the horizontal direction.

[0045] After the fixed block 6 is positioned, the locking bolt 15 on the fixed block 6 is rotated using a tool. The locking bolt 15 pushes the first trapezoidal block 9, which is rotatably connected to its end, to move within the cavity 14. The inclined surface of the first trapezoidal block 9 presses against the second trapezoidal blocks 10 on both sides, causing the second trapezoidal blocks 10 to overcome the tension of the spring 13 and extend outward along the limiting groove 11. The cooperation between the limiting slider 12 and the limiting groove 11 ensures that the movement direction of the second trapezoidal block 10 is stable and avoids deviation. Finally, it is inserted into the corresponding limiting holes 8 on both sides of the fixed housing 5, thereby fixing HVAC pipes of different diameters.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
