Description

Technical Field

[0001] This utility model relates to the field of HVAC piping technology, and in particular to a high-efficiency and energy-saving HVAC piping connection structure. Background Technology

[0002] HVAC systems transport air or water through pipes (air ducts or water pipes), and connection points ensure a complete path from central equipment (such as boilers, air conditioners, and heat pumps) to terminal equipment (such as air vents and radiators). For example, duct systems need to be connected to achieve uniform distribution of heating and cooling, and to prevent airflow short-circuiting or leakage, which could affect the stability of indoor temperature. The connection of HVAC ducts is not only a technical requirement, but also fundamental to ensuring the efficient and safe operation of the system. From the smoothness of air / water flow, energy efficiency improvement, safety protection to functional realization, the rationality and reliability of the connections directly affect the performance and lifespan of the entire system, as follows.

[0003] A search revealed a patent with authorization announcement number CN220037774U, which discloses a heating, ventilation, and air conditioning (HVAC) pipe structure. The structure includes a first pipe and a second pipe. An annular insert plate is fixedly connected to the top of the second pipe. An annular slot for use with the annular insert plate is formed at the bottom of the first pipe. A connecting sleeve is fixedly installed on the outer surface of the first pipe. A matching insert block is formed on the outer surface of the second pipe corresponding to the position of the connecting sleeve. Four first screws are evenly spaced around the outside of the connecting sleeve. One end of each first screw passes through the connecting sleeve, the insert block, and the annular insert plate, extending into the annular insert plate and threadedly connecting to it. This HVAC pipe structure is rationally designed and easy to use. It uses two sets of bolts in opposite directions to connect two or more HVAC pipes, maximizing connection strength and preventing loosening or detachment even after long-term use. Furthermore, the joints have good sealing properties, preventing water leakage and meeting the normal operating requirements of HVAC systems.

[0004] However, the above-mentioned HVAC duct structure still has the following areas for optimization. For example, when installing and connecting pipes, it still requires multiple threaded fasteners, such as screws and bolts, just like traditional connection methods. Using multiple threaded fasteners for connection is not only time-consuming and labor-intensive, but also inefficient. It also requires matching disassembly and assembly tools, such as wrenches. This makes the connection and installation of pipes, as well as subsequent disassembly and maintenance, time-consuming, labor-intensive, and inefficient. Therefore, there is an urgent need for a high-efficiency and energy-saving HVAC duct connection structure to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model discloses a high-efficiency and energy-saving HVAC pipe connection structure. It features a quick-connect mechanism and a quick-locking mechanism, allowing the connection of the first and second pipes to be completed by engaging the mating plate on one side of the second mating seat with the mating groove on one side of the first mating seat. The second mating seat is then rotated to adjust the positions of the four locking plates, aligning them with the locking grooves. Rotating the locking plates further engages them with the locking grooves until the inner side of the L-shaped bend of the locking plate is tightly fitted against the side of the first mating seat furthest from the second mating seat. During this process, pressure is applied to the locking plates until they are firmly locked, compressing the sealing gasket. This quickly and easily completes the connection and fixation between the first and second pipes without the need for threaded fasteners or matching installation tools, saving time and effort and increasing efficiency. In summary, this solves the problems in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] A quick-locking mechanism is located on the side of the first docking seat away from the second docking seat, and the quick-locking mechanism engages with the limiting groove.

[0011] Furthermore, when the inner side of the L-shaped turning surface of the snap-on plate is tightly fitted to the side of the first mating seat away from the second mating seat, the sealing gasket layer is in a compressed state.

[0012] Furthermore, a lifting handle is fixedly connected to the side of the snap-on plate away from the second docking seat, and the lifting handle is fixedly connected to the snap-on plate by welding.

[0013] Furthermore, a first magnet is embedded and fixedly attached to the slot, and a second magnet is attached and fixedly attached to the buckle plate, with the second magnet and the first magnet being attracted and connected.

[0014] Furthermore, the quick-locking mechanism includes a mounting bracket, a pull rod, an abutment plate, and a spring. The quick-locking mechanism has four sets.

[0027] Reference Figures 1-4A high-efficiency and energy-saving HVAC duct connection structure includes a first duct 1 and a second duct 2. A first docking seat 3 is fixedly connected to one end of the first duct 1. An annular docking groove 4 is provided on one side of the first docking seat 3. A second docking seat 5 is fixedly connected to one end of the second duct 2. An annular docking plate 6 is provided on one side of the second docking seat 5. A sealing gasket 7 is attached and fixed to the side of the docking plate 6 away from the second duct 2. The docking plate 6 matches and engages with the docking groove 4, and the sealing gasket 7 abuts and tightens against the deep interior of the docking groove 4. Four mounting grooves 8 are equally spaced on the outer circumference of the first docking seat 3, and four installation grooves 9 are equally spaced on the outer circumference of the second docking seat 5. The size of the installation grooves 9 matches the size of the mounting grooves 8.

[0028] The quick-connecting mechanism 10 includes four latching plates 1001, each L-shaped. A pivot 1002 is provided on both sides of each latching plate 1001. The latching plates 1001 are rotatably mounted inside the mounting groove 9 via the pivot 1002, and are matched and engaged with the latching groove 8. The inner side of the L-shaped turning surface of the latching plate 1001 is closely fitted to the side of the first docking seat 3 away from the second docking seat 5. A through-hole limiting groove 1003 is provided at the L-shaped turning surface of the latching plate 1001. A quick-locking mechanism 11 is located on the side of the first docking seat 3 away from the second docking seat 5, and engages with the limiting groove 1003.

[0029] When the inner side of the L-shaped turning surface of the snap-on plate 1001 is tightly fitted with the side of the first docking seat 3 away from the second docking seat 5, the sealing gasket layer 7 is under pressure and compressed; a lifting handle 1006 is fixedly connected to the side of the snap-on plate 1001 away from the second docking seat 5, and the lifting handle 1006 is fixedly connected to the snap-on plate 1001 by welding; a first magnet 1004 is embedded and fixedly fitted at the snap-on groove 8, and a second magnet 1005 is attached and fixedly fitted at the snap-on plate 1001, and the second magnet 1005 is attracted and connected to the first magnet 1004;

[0030] The quick-locking mechanism 11 includes a mounting bracket 1101, a pull rod 1102, an abutment plate 1103, and a spring 1104. The quick-locking mechanism 11 has four sets. The mounting bracket 1101 is U-shaped. All four mounting brackets 1101 are fixedly installed on the side of the first docking seat 3 away from the second docking seat 5. One end of the pull rod 1102 movably passes through the mounting bracket 1101, and the pull rod 1102 matches and engages with the limiting groove 1003. The abutment plate 1103 is fixedly fitted on the outside of the pull rod 1102. The spring 1104 is movably fitted on the outside of the pull rod 1102, and the two ends of the spring 1104 are respectively fixedly connected to the abutment plate 1103 and the mounting bracket 1101.

[0031] The mounting bracket 1101 has sliding grooves 1105 on both sides inside, and the two sides of the abutment plate 1103 are slidably connected to the two sliding grooves 1105 through sliding connectors.

[0032] In the specific implementation process, when connecting the first pipe 1 and the second pipe 2, the mating plate 6 on one side of the second mating seat 5 can be matched and engaged with the mating groove 4 on one side of the first mating seat 3. The second mating seat 5 is then rotated to adjust the position of the four snap-fit ​​plates 1001, so that the position of the snap-fit ​​plates 1001 is aligned with the position of the snap-fit ​​groove 8. At this time, the pull rod 1102 can be pulled up first to compress the spring 1104. Then, the snap-fit ​​plates 1001 are rotated to match and engage with the snap-fit ​​groove 8 until the inner side of the L-shaped bend of the snap-fit ​​plate 1001 is tightly fitted to the side of the first mating seat 3 away from the second mating seat 5. During this process, force needs to be applied to the snap-fit ​​plates 1001. Until the snap-fit ​​plate 1001 is locked and the sealing gasket 7 is compressed, then the pull rod 1102 is released, the spring 1104 rebounds, and in conjunction with the abutment plate 1103, the pull rod 1102 is driven to reset until the pull rod 1102 matches and engages with the limiting groove 1003. This quickly locks and limits the snap-fit ​​plate 1001, effectively preventing the snap-fit ​​plate 1001 from becoming loose. This effectively prevents the first pipe 1 and the second pipe 2 from becoming loose, which would reduce the sealing performance and affect their normal operation. Thus, the connection, fixation and locking between the first pipe 1 and the second pipe 2 can be completed quickly and conveniently without the need for threaded fasteners and matching installation tools, saving time and effort and increasing efficiency.

[0033] When the inner side of the L-shaped turning surface of the snap-on plate 1001 is tightly fitted with the side of the first docking seat 3 away from the second docking seat 5, the sealing gasket 7 is in a compressed state to ensure that after the snap-on plate 1001 is fastened, the docking plate 6 and the docking groove 4 can be sealed through the compressed sealing gasket 7 to prevent leakage when air or water flows inside the first pipe 1 and the second pipe 2.

[0034] The pull handle 1006 is fixedly connected to the side of the snap-on plate 1001 away from the second docking seat 5 to facilitate the installation and removal of the snap-on plate 1001 by the staff. The pull handle 1006 is fixedly connected to the snap-on plate 1001 by welding to ensure that the pull handle 1006 and the snap-on plate 1001 have high connection strength and are not easy to break or separate.

[0035] The adsorption connection between the second magnet 1005 and the first magnet 1004 can effectively improve the stability of the snap-on plate 1001 after it is snapped in, making it less likely for the snap-on plate 1001 to fall off and separate from the snap-on groove 8 and the first docking seat 3.

[0036] The fact that the two sides of the abutment plate 1103 are slidably connected to the two slide grooves 1105 through sliding connectors can greatly improve the stability of the abutment plate 1103.

[0037] Working principle: When connecting the first pipe 1 and the second pipe 2, the mating plate 6 on one side of the second mating seat 5 can be matched and engaged with the mating groove 4 on one side of the first mating seat 3. The second mating seat 5 is rotated to adjust the position of the four snap-fit ​​plates 1001 so that the position of the snap-fit ​​plates 1001 is aligned with the position of the snap-fit ​​groove 8. At this time, the pull rod 1102 can be pulled up first to compress the spring 1104. Then, the snap-fit ​​plates 1001 are rotated to match and engage with the snap-fit ​​groove 8 until the inner side of the L-shaped bend of the snap-fit ​​plate 1001 is tightly attached to the side of the first mating seat 3 away from the second mating seat 5. During this process, force needs to be applied to the snap-fit ​​plates 1001 until they are snapped into place. Plate 1001 is clamped, and sealing gasket 7 is compressed. Then, pull rod 1102 is released, spring 1104 rebounds, and in conjunction with abutment plate 1103, pull rod 1102 is driven to reset until pull rod 1102 matches and engages with limiting groove 1003. This quickly locks and limits the clamping plate 1001, effectively preventing the clamping plate 1001 from loosening. This effectively prevents the first pipe 1 and the second pipe 2 from becoming loose, thus reducing sealing performance and affecting their normal operation. This quickly and conveniently completes the connection, fixation, and locking of the first pipe 1 and the second pipe 2 without the need for threaded fasteners and matching installation tools, saving time and effort, and is highly efficient and practical.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
