Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically an air conditioning duct that is easy to install. Background Technology

[0002] Air ducts are piping systems used for air transport and distribution. According to their cross-sectional shape, air ducts can be divided into various types such as circular air ducts, rectangular air ducts, and flat oval air ducts. Among them, circular air ducts have the lowest resistance but the largest height dimension and are more complex to manufacture, so rectangular air ducts are mainly used. According to their material, air ducts can be divided into metal air ducts, composite air ducts, and polymer air ducts. Metal air ducts have the advantage of high strength and are widely used in the field of air conditioning installation technology.

[0003] Meanwhile, a type of easy-to-install air conditioning duct with announcement number CN214841560U is disclosed, including an air conditioning duct body. A first duct flange is fixedly installed on one side surface of the air conditioning duct body, and a second duct flange is fixedly installed on the other side surface of the air conditioning duct body. A support plate is movably installed inside the air conditioning duct body near the edges of both ends, and a rubber bushing is movably installed inside the first duct flange.

[0004] The aforementioned easy-to-install air conditioning duct cannot be adjusted according to the length of the duct when installing the flange, requiring readjustment during installation, which is time-consuming, labor-intensive, and reduces work efficiency.

[0005] Therefore, an air conditioning duct that is easy to install is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides an easy-to-install air conditioning duct that eliminates the need for complex tools and extensive manpower for forced connection, significantly improving installation efficiency. This adjustment method is particularly advantageous in narrow or high-ceilinged spaces where installation becomes effortless and simple.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air conditioning duct that is easy to install, including a duct flange one, a rotating handle fixedly provided inside the right side of the duct flange one, a lead screw rotatably provided on the rear side of the rotating handle, a nut spirally provided on the outside of the lead screw, and a duct flange two fixedly provided on the outside of the nut.

[0008] Preferably, a duct body is provided on the right side of the connecting plate, and limiting plates are fixedly provided on both the upper and lower sides of the duct body. A connecting plate is fixedly provided on the outside of the limiting plate, and a connecting column is fixedly provided on the rear side of the connecting plate.

[0009] By adopting the above technical solution, the limiting plates on the upper and lower sides of the duct body cooperate with the connecting plate, and the connecting column one, connecting column two, and fixing block on the rear side of the connecting plate provide reliable support and fixation for the connection of the duct. The limiting plates can limit the shaking of the duct body during installation and use.

[0010] Preferably, a fixing plate is fitted to the outside of the connecting column, a limiting ring is fixed to the rear side of the fixing plate, and a fixing groove is opened on the outer side of the limiting ring.

[0011] By adopting the above technical solution, the fixing plate that fits tightly against the outside of the connecting column, the limiting ring on its rear side, and the fixing groove opened on the outside of the limiting ring further enhance the stability of the duct connection. The fixing plate can fit tightly against the connecting column, and the limiting ring and fixing groove can cooperate with the fixing block to achieve a more secure connection. This double-fixing structure can effectively resist the action of external forces, ensuring that the duct will not loosen during long-term use.

[0012] Preferably, a limiting groove is provided inside the duct flange, and a sealing strip is fixedly provided inside the duct flange.

[0013] By adopting the above technical solution, the limiting groove inside the duct flange serves to position and fix the duct, preventing displacement during installation and use. Simultaneously, the sealing strip fixed inside the duct flange effectively prevents air leakage, improving the energy efficiency of the air conditioning system. During air conditioning operation, good sealing performance reduces energy loss, lowers operating costs, and ensures the cooling or heating effect of the air conditioner.

[0014] Preferably, a connecting plate is fixedly provided on the left side of the first duct flange, a slide rail is fixedly provided inside the connecting plate, a slider is slidably provided inside the slide rail, and the slider is fixedly provided with the second duct flange.

[0015] By adopting the above technical solution, the slide rail and slider inside the connecting plate on the left side of the duct flange one cooperate, and the slider and duct flange two are fixed. This makes the movement of duct flange two more stable and smooth, further reducing the installation difficulty. During installation, duct flange two can slide smoothly on the slide rail with the help of the slider to achieve precise position adjustment, avoiding the jamming and position deviation problems that may occur in traditional installation.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model connects a rotating handle on the right side of duct flange one to a threaded rod, with a nut externally connected to duct flange two. Rotating the handle causes the threaded rod to rotate, moving the nut along the rod and thus moving duct flange two. During installation, workers can easily adjust the distance between the two duct flanges simply by operating the handle, eliminating the need for complex tools and extensive manpower for forced connection, greatly improving installation efficiency. This adjustment method is particularly useful in narrow or high-altitude spaces where operation is difficult, making installation work easy and simple.

[0018] 2. This utility model utilizes a sliding rail and a slider within the connecting plate on the left side of the duct flange one, with the slider and duct flange two fixed together. This makes the movement of duct flange two more stable and smooth, further reducing installation difficulty. During installation, duct flange two can slide smoothly on the sliding rail with the help of the slider, achieving precise position adjustment and avoiding the jamming and positional deviation problems that may occur in traditional installations.

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.

[0025] The following describes an embodiment of this utility model based on its overall structure.

[0026] like Figures 1 to 4As shown, this utility model provides an easy-to-install air conditioning duct, including a duct flange 3. A handle 8 is fixedly installed inside the right side of the duct flange 3. A lead screw 7 is rotatably mounted on the rear side of the handle 8. A nut 6 is screwed onto the outside of the lead screw 7. A second duct flange 5 is fixedly mounted outside the nut 6. The handle 8 on the right side of the duct flange 3 is connected to the lead screw 7, and the nut 6 connects the second duct flange 5 to the lead screw 7. When the handle 8 is rotated, the lead screw 7 rotates, causing the nut 6 to move along the lead screw 7, thereby moving the second duct flange 5. During installation, workers only need to operate the handle 8 to easily adjust the distance between the two duct flanges, eliminating the need for complex tools and a large amount of manpower for forced connection, greatly improving installation efficiency. Especially in narrow or high spaces where operation is difficult, this adjustment method makes installation work easy and simple.

[0027] In this embodiment, a connecting plate 9 is fixedly installed on the left side of the duct flange 3. A slide rail 10 is fixedly installed inside the connecting plate 9, and a slider 11 is slidably installed inside the slide rail 10. The slider 11 is fixedly installed with the duct flange 5. The slide rail 10 and the slider 11 inside the connecting plate 9 on the left side of the duct flange 3 cooperate with each other, and the slider 11 is fixed with the duct flange 5. This makes the duct flange 5 move more smoothly and steadily, further reducing the installation difficulty. During installation, the second duct flange 5 can slide smoothly on the slide rail 10 with the help of the slider 11, achieving precise position adjustment and avoiding the jamming and position deviation problems that may occur in traditional installation. The right side of the connecting plate 9 is provided with the duct body 1. The upper and lower sides of the duct body 1 are fixed with limiting plates 2. The outside of the limiting plate 2 is fixed with a connecting plate 14. The rear side of the connecting plate 14 is fixed with a connecting column 13. The limiting plates 2 on the upper and lower sides of the duct body 1 cooperate with the connecting plate 14. The connecting column 13, connecting column 25 and fixing block 16 on the rear side of the connecting plate 14 provide reliable support and fixation for the connection of the duct. The limiting plate 2 can limit the shaking of the duct body 1 during installation and use. A connecting column 2 15 is fixedly installed on the rear side of connecting column 1 13, and a fixing block 16 is fixedly installed on the outer side of connecting column 2 15. A fixing plate 17 is fitted to the outside of connecting column 1 13, and a limiting ring 18 is fixedly installed on the rear side of the fixing plate 17. A fixing groove 19 is opened on the outer side of the limiting ring 18. The fixing plate 17 fitted to the outside of connecting column 1 13, the limiting ring 18 on its rear side, and the fixing groove 19 on the outer side of the limiting ring 18 further enhance the stability of the duct connection. The fixing plate 17 can fit tightly against connecting column 1 13, and the limiting ring 18 and fixing groove 19 can cooperate with the fixing block 16 to achieve a more secure connection. This double-fixed structure effectively resists external forces, ensuring that the duct will not loosen during long-term use. The duct flange 3 has an internal limiting groove 12, and a sealing strip 4 is fixedly installed inside. The limiting groove 12 inside the duct flange 3 serves to position and fix the duct, preventing displacement during installation and use. Simultaneously, the sealing strip 4 fixed inside the duct flange 3 effectively prevents air leakage, improving the energy efficiency of the air conditioning system. During air conditioning operation, good sealing performance reduces energy loss, lowers operating costs, and ensures the cooling or heating effect of the air conditioner.

[0028] The working principle and process of an easy-to-install air conditioning duct:

[0029] In the installation of an easy-to-install air conditioning duct, the duct flange 3 is placed in a suitable installation position. A sealing strip 4 is installed inside the duct flange 3 to prevent air leakage and improve the sealing and energy-saving effect of the duct system. A rotating handle 8 is installed inside the right side of the duct flange 3, ensuring that the handle 8 can rotate flexibly. A threaded rod 7 is installed on the rear side of the rotating handle 8, allowing the threaded rod 7 to rotate with the rotating handle 8. A nut 6 is screwed onto the outside of the threaded rod 7 and fixedly connected to the duct flange 5. By rotating the rotating handle 8, the threaded rod 7 rotates, causing the nut 6 to move linearly along the threaded rod 7, thereby adjusting the distance between the duct flange 5 and the duct flange 3, facilitating subsequent installation and connection. A connecting plate 9 is fixed to the left side of the duct flange 3. A slide rail 10 is installed inside the connecting plate 9, and a slider 11 is installed inside the slide rail 10, allowing the slider 11 to slide freely on the slide rail 10. The slider 11 is fixedly set to the duct flange 2 5. When the position of the duct flange 2 5 is adjusted, the slider 11 will slide on the slide rail 10 to ensure smooth movement. The duct body 1 is placed on the right side of the connecting plate 9, and the limiting plates 2 on the upper and lower sides of the duct body 1 are aligned with the limiting groove 12. The connecting column 13 is inserted into the fixing plate 17, and the fixing plate 17 is tightly fitted to the connecting column 13. The fixing block 16 is inserted into the fixing groove 19 for fixation, so that the air conditioning duct can be installed quickly.
