Description

Technical Field

[0001] This utility model relates to the field of air duct technology, specifically a novel composite integrated air duct. Background Technology

[0002] Composite ducts are a type of piping system used for air transmission and distribution. They are made of multiple layers of composite materials and can be used in various applications such as air conditioning, ventilation, and exhaust. They have advantages such as lightweight, durability, and ease of construction and are widely used in construction, industry, and aerospace.

[0003] In existing technologies, composite integrated air ducts are fixed by flanges and multiple bolts between two composite integrated air ducts during installation and connection. This method is prone to air leakage when the composite integrated air duct is ventilated if the bolts are not fully tightened or the outer surface of the flange is deformed. Furthermore, the repeated disassembly of bolts is extremely inconvenient for maintenance and replacement. Therefore, we propose a new type of composite integrated air duct to solve the above problems. Utility Model Content

[0011] Preferably, sliding grooves are provided on both sides of the inner cavity of the movable groove, and a slider is slidably connected to the inner cavity of the sliding groove. The end of the slider away from the sliding groove is fixedly connected to the movable plate.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Example 1:

[0029] Reference Figure 1-5A novel composite integrated air duct includes an I-beam connecting plate 1, with grooves 2 on both sides of the I-beam connecting plate 1. Air duct bodies 3 are housed within the inner cavities of both grooves 2. Movable grooves 4 are formed at the top and bottom of the inner cavities of the I-beam connecting plate 1. Limiting components 5 are provided within the inner cavities of the movable grooves 4. The limiting components 5 include movable plates 501 disposed within the inner cavities of the movable grooves 4. Limiting blocks 502 are fixedly connected to both sides of the bottom of the movable plates 501. Limiting grooves 503, used in conjunction with the limiting blocks 502, are formed on both sides of the top and bottom of the two air duct bodies 3. Pull handles 50 are fixedly connected to the opposite sides of the two movable plates 501. 4. Limiting springs 505 are fixedly connected to the opposite sides of the two movable plates 501. By setting the I-shaped connecting plate 1, it is easy to connect the two air duct bodies 3, improving the convenience of connection. By setting the limiting component 5, it is easy to disassemble and assemble the two connected air duct bodies 3, making it convenient for the two air duct bodies 3 to be quickly connected and limited. This achieves the purpose of making the connection of square air ducts simple, not requiring multiple sets of bolts, fast connection speed, and easy disassembly during later maintenance. At the same time, the setting of the sealing ring 9 can increase the sealing performance when the two air duct bodies 3 are connected, avoiding air leakage.

[0030] Example 2:

[0031] Reference Figure 1 , Figure 3 and Figure 4 The handle 504 passes through the movable groove 4 and extends to the outside of the I-beam connecting plate 1. The surface of the handle 504 is provided with anti-slip texture to facilitate operation. Slide grooves 6 are provided on both sides of the inner cavity of the movable groove 4. A slider 7 is slidably connected to the inner cavity of the slide groove 6. The end of the slider 7 away from the slide groove 6 is fixedly connected to the movable plate 501, which can limit and guide the movement of the movable plate 501, increasing the stability of the movable plate 501 when moving up and down. The duct body 3 includes an inner sheet metal 301. A fire-retardant core layer 302 is provided on the outer surface of the inner sheet metal 301. An outer layer of fire-retardant core layer 302 is provided on the outer surface of the fire-retardant core layer 302. The inner and outer layers of color steel 303 increase the strength and rigidity of the duct, extending its service life. The fire-retardant core layer 302 provides fire resistance and insulation. The inner surface of the inner steel 301 is coated with anti-corrosion paint 8, which is made of polytetrafluoroethylene, further enhancing the duct's resistance to acids and alkalis, corrosion, various organic solvents, and high temperatures. The inner cavities of the grooves 2 are equipped with sealing rings 9, which fit tightly against the duct body 3, increasing the sealing performance when two duct bodies 3 are connected, preventing air leakage.

[0032] The working principle is as follows:

[0033] In use, insert the opposite ends of the two duct bodies 3 into the grooves 2 on both sides of the I-beam connecting plate 1. As the duct body 3 is inside the groove 2, and under the design of the inclined side of the limiting block 502, it will automatically push the limiting block 502 to move. Finally, the limiting block 502 will automatically engage with the limiting groove 503, which makes it easy to connect the two ducts and improves the convenience of connection. At the same time, it also makes it easy to quickly dock and limit the two duct bodies 3. It makes the connection of square ducts simple, does not require multiple sets of bolts, has a fast connection speed, and is easy to disassemble during later maintenance. In addition, the setting of the sealing ring 9 can increase the sealing of the two duct bodies 3 when connected, and prevent air leakage.

[0034] When it is necessary to disassemble the air duct, the movable plate 501 is moved by pulling the handle 504. The movable plate 501 can move the limiting block 502 out of the limiting groove 503, so that the two air duct bodies 3 can be easily moved out of the grooves 2 on both sides of the I-beam connecting plate 1, thus realizing the quick disassembly of the air duct.

[0035] During the use of the duct, the inner sheet metal 301 and the outer color steel 303 can increase the strength and rigidity of the duct and improve its service life. The fireproof and flame-retardant core layer 302 can achieve the purpose of fireproofing and flame retardancy and also has the function of heat insulation. Finally, the anti-corrosion coating 8 adopts a polytetrafluoroethylene coating layer, which further increases the acid and alkali resistance, corrosion resistance, resistance to various organic solvents and high temperature resistance of the inner surface of the duct.

[0036] In summary, this novel composite integrated air duct, by setting an I-beam connecting plate 1, facilitates the connection of two air duct bodies 3, improving the convenience of connection. The setting of the limiting component 5 facilitates the disassembly and assembly of the two connected air duct bodies 3, enabling quick docking and limiting of the two air duct bodies 3. It achieves the goal of simple connection of square air ducts, eliminating the need for multiple sets of bolts, fast connection speed, and convenient disassembly for later maintenance. At the same time, the setting of the sealing ring 9 can increase the sealing performance when the two air duct bodies 3 are connected, preventing air leakage.
