Technical Field
[0001] This utility model relates to the field of ventilation duct equipment technology, specifically an assembled sealed ventilation duct. Background Technology
[0002] Ventilation ducts are pipe systems used for air transport and circulation. They are typically made of metal (such as galvanized steel or stainless steel), plastic (such as PVC or PP), or composite materials, and are mostly circular or rectangular in shape. They are widely used in buildings, industrial plants, and commercial spaces. In conjunction with fans, air vents, and other equipment, they achieve functions such as indoor and outdoor air exchange, ventilation, temperature regulation, and pollutant removal. They play a crucial role in ensuring indoor air quality, regulating ambient temperature and humidity, and removing harmful gases and dust, and are an important component of ventilation and air conditioning systems.
[0003] Traditional ventilation ducts are typically installed using on-site welding or prefabrication. On-site welding has many drawbacks, such as generating harmful gases and fumes that pollute the construction environment, and the welding quality is greatly affected by the skill level of the workers, easily leading to uneven welds, air leaks, and other problems that affect the sealing and service life of the ventilation ducts. While prefabricated ventilation ducts ensure the quality of the ducts to a certain extent, their large size makes transportation and installation difficult, especially in spaces with limited space, significantly increasing construction difficulty and costs.
[0004] Therefore, we need to propose an assembled sealed ventilation duct. Utility Model Content
[0005] The purpose of this utility model is to provide an assembled sealed ventilation duct, which adopts an assembled structure and is composed of multiple duct units. It is small in size, easy to transport, and especially suitable for installation in places with limited space, which greatly reduces the difficulty and cost of transportation and installation, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An assembled sealed ventilation duct, comprising:
[0008] Multiple sets of pipe units are assembled together. Each pipe unit includes a main body, a first connecting plate, and a second connecting plate. The first connecting plate is integrally formed and disposed at one end of the main body, and the second connecting plate is integrally formed and disposed at the other end of the main body. Assembly holes are correspondingly opened on the first connecting plate and the second connecting plate. The first connecting plate and the second connecting plate of adjacent pipe units are mated together and fixed together by fixing screws.
[0009] It also includes a sealing structure, which is set at both ends of the main body. The sealing structure includes a sealing ring and a sealing groove. The sealing ring is set at the port of the main body with the second connecting plate, and the sealing groove is opened at the port of the main body with the first connecting plate. When adjacent pipe units are combined, the sealing rings of the adjacent pipes are inserted into the interior of the sealing groove.
[0010] Preferably, it also includes a support structure for supporting the pipe unit, which is disposed at the bottom of the main body. The support structure includes a support plate and connecting arms. Two sets of connecting arms are symmetrically arranged on the support plate. When the support structure supports the main body, the support plate is attached to the bottom of the main body and the connecting arms are attached to the outer walls of both sides of the main body.
[0011] Two sets of connecting blocks are symmetrically arranged on the top of the main body. The upper end of the support arm and the connecting blocks are fixed together by fixing screws, so that the support structure can not only provide good support for the pipe unit, but also be detachable, and there is no need to weld or drill holes on the pipe to ensure the integrity and sealing of the pipe.
[0012] Preferably, it also includes a hoisting structure for hoisting the pipe unit, which is disposed above both sides of the main body. The hoisting structure includes a hoisting component and a lifting rod. The hoisting component is welded to the upper end of the lifting rod and fixed to the indoor ceiling with bolts.
[0013] A disc is welded to the lower end of the boom, and an adjusting screw is set at the center of the bottom of the disc. The adjusting screw is threaded onto the end of the support plate. The lifting height can be adjusted according to the actual situation by rotating the disc to adjust the extension length of the adjusting screw.
[0014] Preferably, it also includes a locking disc, which is disposed on the bottom surface of the end of the support plate. The locking disc is threadedly installed on the adjusting screw. After the adjusting screw adjusts the hoisting height, the locking disc is threadedly installed on the adjusting screw and abuts against the bottom surface of the end of the support plate to form a double thread to lock the height.
[0015] Preferably, it also includes a positioning structure for preventing loosening of the connection between adjacent pipe units, which is disposed at both ends of the main body. The positioning mechanism includes an upper positioning block and a lower positioning block, with the upper positioning block disposed on both sides of the first connecting plate and the lower positioning block disposed on both sides of the second connecting plate.
[0016] Preferably, the upper positioning block and the lower positioning block have corresponding positioning holes. When adjacent pipe units are connected, the first connecting plate and the second connecting plate on the first connecting plate and the second connecting plate are connected, and the upper positioning block and the lower positioning block are staggered vertically. The positioning holes on the upper positioning block and the lower positioning block are connected and fixed by fixing screws, thereby preventing the connection of adjacent pipe units from becoming loose.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. By abandoning the traditional on-site welding method, welding operations are no longer required on the installation site, fundamentally eliminating the pollution of the construction environment by harmful gases and fumes generated during the welding process, and providing a healthier and safer working environment for construction workers.
[0019] 2. Compared with prefabricated ventilation ducts, this ventilation duct adopts an assembled structure, which is composed of multiple duct units. It is small in size, easy to transport, and especially suitable for installation in places with limited space, which greatly reduces the difficulty and cost of transportation and installation.
[0020] 3. Sealing structures are installed at both ends of the main body. Through the cooperation of the sealing ring and the sealing groove, when adjacent pipe units are combined, the sealing ring is inserted into the sealing groove, achieving a reliable seal between adjacent pipe units, effectively preventing air leakage, ensuring the normal operation of the ventilation system, and extending the service life of the ventilation duct.
