Description

Technical Field

[0001] This utility model relates to the field of ventilation duct technology, and in particular to an assembled ventilation duct. Background Technology

[0002] Ventilation ducts, as an important component of building ventilation systems, are widely used in industrial plants, commercial buildings, and residential buildings. Their function is to achieve effective air circulation and exchange. Traditional ventilation ducts are usually made of metal or composite materials and assembled by means of flange connection or bolt fixing. However, as the construction industry's requirements for construction efficiency, installation convenience, and maintenance convenience continue to increase, the traditional assembly method of ventilation ducts has gradually revealed many limitations. To address this, a modular ventilation duct has emerged, aiming to achieve rapid splicing and efficient installation through optimized structural design, thereby meeting the modern building's demand for efficient and flexible ventilation systems.

[0003] In existing technologies, the assembly of ventilation ducts mainly relies on flange connections or bolt fixation. Flange connections typically involve welding flanges to the ends of two pipe sections and then tightening the flanges with bolts and nuts to achieve pipe splicing. Another common method is to use socket connections, which involves setting a flared end at one end of a pipe section, inserting the other pipe section into the flared end, and then fixing it with sealant or clamps.

[0004] Although existing technologies can meet the basic functional requirements of ventilation ducts, their assembly process suffers from significant inefficiencies. For example, flange connections require aligning bolt holes one by one and tightening bolts, while socket connections require applying sealant and waiting for it to cure. These steps are not only time-consuming and labor-intensive, but also require operators to have a high level of technical skill. Furthermore, the limitations of traditional assembly methods are even more pronounced in confined or high-altitude working environments, further reducing construction efficiency. Therefore, a modular ventilation duct is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an assembled ventilation duct, which aims to improve the existing technology where flange connections require aligning bolt holes one by one and tightening bolts, and socket connections require applying sealant and waiting for it to cure.

One end of the spring 9 is fixedly connected to the side wall of the sliding plate 7, and the other end of the spring 9 is fixedly connected to the side wall of the sliding plate 8. An interception assembly is installed inside the air duct 2.

[0035] Reference Figures 1-5The interception component includes a sliding frame 11 and a filter screen 12. The sliding frame 11 is slidably connected inside the second air duct 2 and is used to guide the installation and removal path of the filter screen 12. The filter screen 12 is set inside the sliding frame 11 and is used to filter dust and impurities in the air. A pull rod 13 is provided on the outer wall of the filter screen 12, which facilitates manual pulling of the filter screen 12 for cleaning or replacement. One side of the pull rod 13 is fixedly connected to the side wall of the filter screen 12 to ensure stability during operation. A snap-fit ​​component is provided inside the filter screen 12 to fix the position of the filter screen 12 in the second air duct 2. The snap-fit ​​component includes a locking ball 14, which engages with the second air duct 2 to achieve quick locking of the filter screen 12. The locking ball 14 is slidably connected inside the sliding frame 11, allowing... The ball 14 extends and retracts. A connecting plate 15 is fixedly connected to the inner wall of the ball 14.

[0036] Working principle: When assembling air duct 1 and air duct 2, pulling handles 15 and 26 moves sliding plates 17 and 28 towards the center, thereby causing the locking post 10 to slide and compress spring 19. Then, the connecting frame 3 and locking plate 4 on the side wall of air duct 22 slide into air duct 1. Releasing handles 15 and 26 resets spring 19, causing sliding plates 17 and 28 to move in the opposite direction, thereby engaging locking post 10 with locking plate 4, completing the splicing of air duct 1 and air duct 2. When installing the interception component, the sliding frame 11 is slid into the air duct 2, which in turn drives the filter 12 into the air duct 2. At this time, the retaining ball 14 is squeezed, which drives the connecting plate 15 and the limiting plate 16 to slide and compress the spring 17. When the sliding frame 11 is in place, the spring 17 resets, which drives the limiting plate 16, the connecting plate 15 and the retaining ball 14 to move in the opposite direction, so that the retaining ball 14 engages with the air duct 2 to fix the filter 12. When the filter 12 needs to be cleaned, the filter 12 can be removed from the sliding frame 11 by pulling the lever 13.
