Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning technology, and more specifically, to a heating, ventilation and air conditioning duct structure with airflow balance regulation function. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) systems play a vital role in modern buildings. They are not only devices for regulating indoor temperature, but also key systems for maintaining indoor air quality, ensuring human comfort, and saving energy. In HVAC systems, air ducts serve as channels for transporting and distributing air, and the rationality of their structural design directly affects the performance efficiency, energy consumption indicators, and user comfort experience of the entire system.

[0003] A search revealed Chinese patent application number 202420289384.2, which discloses an air conditioning heating duct structure, relating to the field of air conditioning heating duct technology. The structure includes a first ventilation duct, with a first mounting bracket threaded to one side of the first ventilation duct. A first ventilation opening is provided on one side of the first mounting bracket, and a filter plate is slidably connected to the inner wall of the first ventilation opening, covering the inner side of the first ventilation opening. A second mounting bracket is threaded to one side of the first mounting bracket. This utility model employs the above structure. When warm air is sent into the first ventilation duct, its filter plate can effectively filter the warm air, thereby removing a large amount of dust. The filtered warm air then enters the second ventilation duct through the second ventilation opening, thus effectively improving the quality of the warm air itself. Due to the presence of a baffle, one side of the filter plate is blocked, preventing the filter plate from slipping off. Although the above-mentioned patent can achieve the connection between ventilation ducts through the first mounting bracket, the second mounting bracket and the first bolt, it still has the following shortcomings in use: This connection method requires all the screw holes on the first mounting bracket and the second mounting bracket to be aligned during installation, which cannot accommodate the deviation between the pipes, and requires extremely high construction precision. Moreover, multiple bolts need to be tightened one by one during installation, which is cumbersome, time-consuming and inefficient.

[0004] Therefore, there is an urgent need for a heating, ventilation, and air conditioning duct structure with airflow equalization and regulation functions to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a heating, ventilation and air conditioning duct structure with airflow equalization and regulation function to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A heating, ventilation, and air conditioning duct structure with airflow equalization and regulation function includes a main duct and branch ducts, wherein an air volume regulating valve is installed in the middle of the branch duct, and further includes: A connector is provided between the main pipe and the branch pipe. Both ends of the connector are fixedly equipped with multiple evenly distributed buckles. Both the main pipe and the branch pipe are provided with multiple first insertion holes that cooperate with the buckles. The connector includes a first joint and a second joint, and a folded pipe section is fixedly connected between the first joint and the second joint. Two sets of connecting mechanisms are symmetrically arranged on the outer wall of the second connector; An adjustable limiting component is disposed on the outside of the first connector and connected to the end of the connecting mechanism away from the second connector. The adjustable limiting component includes a frame on which a longitudinal limiting adjustment mechanism and a lateral limiting adjustment mechanism that cooperate with the first connector are installed.

[0007] As a preferred technical solution of this application, multiple plug rods are fixedly connected to both the main pipeline and the branch pipeline, and the first joint and the second joint are each provided with a second plug hole that cooperates with the plug rod.

[0008] As a preferred technical solution of this application, the longitudinal limiting adjustment mechanism includes a first bolt, which is disposed through the bottom center of the frame and threadedly connected to the frame, and a pad is rotatably installed on the top of the frame.

[0009] As a preferred technical solution of this application, the lateral limiting adjustment mechanism includes two first mounting seats symmetrically arranged inside the frame body. The first mounting seats are fixedly connected to the side wall of the frame body with a second bolt penetrating the frame body, and the outer side of the second bolt is threaded with a nut located outside the frame body.

[0010] As a preferred technical solution of this application, the first mounting base has a sliding groove on the side wall away from the frame, and a slider that cooperates with the sliding groove is fixedly installed on the outer wall of the first connector.

[0011] As a preferred technical solution of this application, the connecting mechanism includes a second mounting seat fixedly connected to the outer wall of the second joint, one end of the second mounting seat is provided with a mounting groove, a connecting arm fixedly connected to the frame is slidably installed inside the mounting groove, and a third bolt with one end extending into the mounting groove is threadedly connected to the outer wall of the second mounting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By setting up a first joint, a second joint, and a folded pipe section, the flexible folded pipe section can adjust the position between the first joint and the second joint through its own flexible deformation during use. This can compensate for the axial and radial deviations between the main pipeline and the branch pipeline, greatly reducing the accuracy requirements during construction. 2. By setting up a lateral limiting adjustment mechanism and a longitudinal limiting adjustment mechanism, not only can the position of the first joint be adjusted laterally and longitudinally, but also after the connector is connected to the main pipeline and branch pipeline, the lateral limiting adjustment mechanism and the longitudinal limiting adjustment mechanism can work together with the connection mechanism to form a rigid connection between the first joint and the second joint, which offsets the flexible characteristics of the folded pipe section, ensures the structural stability of the pipeline system when subjected to airflow vibration and pressure, and avoids the loosening of the connection caused by airflow impact or vibration. 3. By setting clips and first insertion holes, when connecting the main pipe and branch pipes, the clips at both ends of the connector are inserted into the first insertion holes at the ends of the main pipe and branch pipe respectively, so that the main pipe and branch pipe can be connected. There is no need to tighten the bolts one by one, which simplifies the installation operation steps, reduces the labor intensity of the installers, and effectively improves the installation efficiency.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0016] like Figures 1-6As shown, this embodiment proposes a heating, ventilation, and air conditioning duct structure with airflow equalization adjustment function, including a main duct 1 and branch ducts 2. An airflow regulating valve 11 is installed in the middle of each branch duct 2, which can evenly adjust the airflow of each branch duct 2. The structure also includes a connector 3, disposed between the main duct 1 and the branch ducts 2. Multiple evenly distributed clips 5 are fixedly installed at both ends of the connector 3. Multiple first insertion holes 6 are provided on both the main duct 1 and the branch ducts 2 to cooperate with the clips 5. By setting the clips 5 and the first insertion holes 6... When connecting the main pipe 1 and the branch pipe 2, the clips 5 at both ends of the connector 3 are inserted into the first insertion holes 6 at the ends of the main pipe 1 and the branch pipe 2, respectively, to achieve the installation connection between the main pipe 1 and the branch pipe 2. This eliminates the need to tighten bolts one by one, simplifying the installation process, reducing the labor intensity of installers, and effectively improving installation efficiency. The connector 3 includes a first joint 31 and a second joint 32, with a folded pipe section 33 fixedly connected between the first joint 31 and the second joint 32. This connection is achieved by setting the first joint 31, the second joint 32, and the folded pipe section 33. The flexible folded pipe section 33, during use, can adjust the position between the first joint 31 and the second joint 32 through its flexible deformation, compensating for the axial and radial deviations between the main pipeline 1 and the branch pipeline 2, significantly reducing the precision requirements during construction. Two sets of connecting mechanisms 9 are symmetrically arranged on the outer wall of the second joint 32. The adjustable limiting component 4 is located on the outside of the first joint 31 and connected to the end of the connecting mechanism 9 away from the second joint 32. The adjustable limiting component 4 includes a frame 41, on which a longitudinal limiting adjustment mechanism and a lateral limiting adjustment mechanism are installed to cooperate with the first joint 31. By setting the lateral limiting adjustment mechanism and the longitudinal limiting adjustment mechanism, after the connector 3 is connected to the main pipeline 1 and the branch pipeline 2, the lateral limiting adjustment mechanism and the longitudinal limiting adjustment mechanism can cooperate with the connecting mechanism 9 to form a rigid connection between the first joint 31 and the second joint 32, offsetting the flexible characteristics of the folded pipe section 33, ensuring the structural stability of the pipeline system when subjected to airflow vibration and pressure, and avoiding loosening of the connection due to airflow impact or vibration.

[0017] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, multiple insertion rods 8 are fixedly connected to both the main pipe 1 and the branch pipe 2, and the first connector 31 and the second connector 32 are each provided with a second insertion hole 7 that cooperates with the insertion rods 8. It should be noted that the insertion rods 8 and the second insertion holes 7 are provided to assist in the positioning of the main pipe 1 and the branch pipe 2 when connected to the connector 3, and at the same time, they can also distribute the force on the buckle 5.

[0018] like Figure 1 , Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the longitudinal limiting adjustment mechanism further includes a first bolt 44, which is disposed through the center of the bottom of the frame 41 and threadedly connected to the frame 41. A pad 45 is rotatably mounted on the top of the frame 41. It should be noted that, in use, the position of the pad 45 can be adjusted by rotating the first bolt 44. The pad 45 abuts against the bottom of the first connector 31 to limit its longitudinal movement. In use, rotating the first bolt 44 can also push the first connector 31 to move longitudinally through the pad 45, thereby realizing the longitudinal adjustment of the first connector 31. During longitudinal adjustment, the slider 10 on the outer wall of the first connector 31 will slide in the groove 43 of the first mounting base 42, thereby limiting and guiding the first connector 31.

[0019] like Figure 1 , Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the lateral limiting adjustment mechanism further includes two first mounting seats 42 symmetrically arranged inside the frame 41. A second bolt 46, penetrating the frame 41, is fixedly connected to the side wall of the first mounting seat 42 facing the frame 41. A nut 47, located outside the frame 41, is threaded onto the outer side of the second bolt 46. A groove 43 is formed on the side wall of the first mounting seat 42 away from the frame 41. A slider 10, cooperating with the groove 43, is fixedly installed on the outer wall of the first connector 31. It should be noted that during use, rotating the nut 47 adjusts the position of the second bolt 46, thereby adjusting the position of the first mounting seat 42, allowing the slider 10 to engage with the groove 43. Thus, the lateral limiting of the first connector 31 is achieved through the cooperation of the two first mounting seats 42. Simultaneously, during use, rotating the two nuts 47 on the two second bolts 46 in the opposite direction adjusts the position of the first mounting seat 42, pushing the first connector 31 to move laterally, thereby compensating for the lateral error between the main pipeline 1 and the branch pipeline 2.

[0020] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in a preferred embodiment, based on the above method, the connecting mechanism 9 further includes a second mounting base 92 fixedly connected to the outer wall of the second connector 32. One end of the second mounting base 92 is provided with a mounting groove. A connecting arm 91, fixedly connected to the frame 41, is slidably mounted inside the mounting groove. A third bolt 93, with one end extending into the mounting groove, is threadedly connected to the outer wall of the second mounting base 92. It should be noted that during use, the position of the frame 41 can be adjusted by adjusting the length of the connecting arm 91 inserted into the mounting groove. After adjustment, rotating the third bolt 93 so that one end abuts against the connecting arm 91 can fix the connecting arm 91. During use, the frame 41 can also be pulled to slide the connecting arm 91 within the mounting groove, thereby compensating for radial errors between the main pipeline 1 and the branch pipeline 2.

[0021] Specifically, when using this HVAC duct structure with airflow equalization adjustment function: First, connect the second connector 32 to the main pipe 1 through the buckle 5 and the first insertion hole 6. Then, insert the slider 10 on the outer wall of the first connector 31 into the groove 43 on the first mounting base 42. Next, insert the connecting arm 91 into the mounting groove at the end of the second mounting base 92. Then, rotate the first bolt 44 to adjust the longitudinal position of the first connector 31 through the pad 45 to compensate for the longitudinal error between the main pipe 1 and the branch pipe 2. After the longitudinal adjustment is completed, rotate the two second bolts in the opposite direction. The two nuts 47 on the bolt 46 adjust the position of the first mounting base 42, thereby pushing the first joint 31 to move laterally to compensate for the lateral error between the main pipe 1 and the branch pipe 2. After the longitudinal and lateral adjustments are completed, the frame 41 is pulled to drive the connecting arm 91 to slide in the mounting groove to compensate for the radial error between the main pipe 1 and the branch pipe 2. After the adjustment is completed, the third bolt 93 is tightened and fixed by abutting one end against the outer wall of the connecting arm 91. During the adjustment process, the flexible folded pipe section 33 will deform as the first joint 31 moves.
