Description

Technical Field

[0001] The utility model relates to the technical field of installation of warm air ducts, in particular to a warm air duct convenient for installation. Background Technique

[0002] Warm air ducts are used for the transmission of cold and warm air in HVAC systems. Generally, warm air ducts are made of galvanized sheets and the various sections of warm air ducts are connected by flanges. Traditional galvanized warm air ducts and flanges are generally connected by welding or riveting, and their structures are relatively complex; according to the cross-sectional shape, air ducts can be divided into various types such as circular air ducts, rectangular air ducts, and oval air ducts. Among them, the circular air duct has the smallest resistance but the largest height dimension and is complex to manufacture. Therefore, rectangular air ducts are mostly used in actual applications. However, when the existing warm air ducts are butt-connected and installed, most of them are assembled and installed by using a clamp in cooperation with bolts and nuts, or by welding, making the connection between the air ducts not convenient enough. Installers need to spend more time installing the air ducts, reducing the installation efficiency of the installers. Moreover, the sealing performance at the connection between the air ducts is not strong enough, prone to air leakage problems. At the same time, the structural strength at the connection between the air ducts also needs to be enhanced. Content of the Utility Model

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Referring to Figures 1 to 4 As shown, the present utility model provides a warm air ventilation pipe that is convenient for installation, including: a pipe body 8, an inner side surface of the pipe body 8 is fixedly connected with a heat preservation layer 9, and both ends of the heat preservation layer 9 are fixedly connected with a main mounting plate 6 and a sub-mounting plate 11 through grooves respectively, and a sub-sealing layer 12 is fixedly connected to a side surface of the sub-mounting plate 11, positioning plates 10 are symmetrically connected to an inner side surface of the sub-mounting plate 11, and fixing rods 5 are correspondingly connected to positions on the inner side surface of the main mounting plate 6 corresponding to the positioning plates 10. At the same time, fitting plates 7 are symmetrically connected to both ends of an outer side surface of the pipe body 8, and fitting grooves 4 are correspondingly opened at positions on the inner side surface of the reinforcing plate 1 corresponding to the fitting plates 7, and a main sealing layer 3 is fixedly connected to the middle of the inner side surface of the reinforcing plate 1.

[0019] In this embodiment, the fixing rods 5 of the first group of pipe bodies 8 are inserted into the through holes of the positioning plates 10 of the second group of pipe bodies 8, so that the first group of pipe bodies 8 and the second group of pipe bodies 8 can be successfully docked. The side surface of the main mounting plate 6 of the first group of pipe bodies 8 will abut against the sub-sealing layer 12 provided on the side surface of the sub-mounting plate 11 in the second group of pipe bodies 8, thereby assisting in enhancing the sealing performance at the connection of the two groups of pipe bodies 8. After that, the two groups of reinforcing plates 1 are pushed closer to each other from both sides of the pipe body 8, so that the fitting grooves 4 opened in the inner cavity of the reinforcing plate 1 can respectively fit the fitting plates 7 provided on the outer side surfaces of the first group of pipe bodies 8 and the second group of pipe bodies 8. The fastening rods 2 in one group of reinforcing plates 1 are screwed into the corresponding screw holes opened in the other group of reinforcing plates 1 through the provided threaded structure, so as to complete the fixed connection between the two groups of reinforcing plates 1. Furthermore, the secondary fixed connection at the connection of the two groups of pipe bodies 8 is realized through the reinforcing plate 1 and the fastening rod 2, and the main sealing layer 3 provided on the inner side surface of the reinforcing plate 1 abuts against the outer side surface at the connection of the two groups of pipe bodies 8, effectively enhancing the sealing performance and structural strength at the connection of the warm air ventilation pipe and improving the installation efficiency of the warm air ventilation pipe.

[0020] As a preferred implementation manner, both the pipe body 8 and the heat preservation layer 9 are in a square tube structure, and the two groups of grooves opened at both ends of the heat preservation layer 9 are in a square frame structure, and the cross section formed by the combination of the grooves and the heat preservation layer 9 is in a convex shape structure.

[0021] In this embodiment, as Figure 1 and Figure 4, the setting of the pipe body 8 can enhance the overall structural strength of the warm air duct, while the setting of the heat insulation layer 9 can effectively reduce the heat exchange efficiency between the inside and outside of the pipe body 8, ensuring that the air flow can smoothly flow inside the warm air duct.

[0022] As a preferred embodiment, both the main mounting plate 6 and the auxiliary mounting plate 11 are in the shape of a square tube, and the main mounting plate 6 and the auxiliary mounting plate 11 respectively match the sizes of the grooves opened at both ends of the heat insulation layer 9. At the same time, the inner sides of the main mounting plate 6 and the auxiliary mounting plate 11 are in the same plane as the inner side of the heat insulation layer 9.

[0023] In this embodiment, as shown in Figure 1 and Figure 4 , the inner sides of the main mounting plate 6, the auxiliary mounting plate 11 and the heat insulation layer 9 are all in the same plane, thereby effectively improving the smoothness of the air flow when flowing at the connection of the warm air duct.

[0024] As a preferred embodiment, three groups of fixing rods 5 are respectively and equidistantly fixedly connected to the four sides of the inner cavity of the main mounting plate 6. The twelve fixing rods 5 are all in the shape of long strips, and the end faces at both ends of the fixing rod 5 are in the shape of squares.

[0025] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the setting of the fixing rod 5 can assist in enhancing the structural strength at the connection between adjacent warm air ducts and can also assist in enhancing the splicing efficiency between adjacent warm air ducts.

[0026] As a preferred embodiment, three groups of positioning plates 10 are respectively and equidistantly fixedly connected to the four sides of the inner cavity of the auxiliary mounting plate 11. The twelve positioning plates 10 are all in the shape of rectangles, and the end face of the positioning plate 10 is in the shape of a concave character. At the same time, the positions of the positioning plate 10 and the fixing rod 5 correspond one by one.

[0027] In this embodiment, as shown in Figure 1 , Figure 3 and Figure 4 , the through holes opened in the positioning plate 10 match the sizes of the fixing rods 5, thereby effectively enhancing the stability at the connection between adjacent warm air ducts.

[0028] As a preferred embodiment, four groups of fitting plates 7 are symmetrically connected to both ends of the outer side of the pipe body 8. The four groups of fitting plates 7 are all in the shape of rectangles. The length of the fitting plate 7 is equal to the width of the outer side of the pipe body 8, and the fitting plate 7 matches the size of the fitting groove 4 opened on the inner side of the reinforcing plate 1.

[0029] In this embodiment, as shown in Figure 1 and Figure 4, the sizes of the fitting plate 7 and the fitting groove 4 are adapted to each other, which can assist in enhancing the stability of the connection between the reinforcement plate 1 and the pipe body 8. Moreover, the fitting plate 7 and the fixing rod 5 are vertically distributed in different planes. Therefore, the reinforcement plate 1 can secondarily fix the connection part of the warm air duct through the fitting plate 7, enhancing the stability of the connection part of the warm air duct.

[0030] As a preferred embodiment, there are two groups of reinforcement plates 1. Both groups of reinforcement plates 1 are in a U-shaped structure. The main sealing layer 3 fixedly connected to the inner side surface of the reinforcement plate 1 is in a U-shaped structure. And the upper end of one group of reinforcement plates 1 is movably connected to the fastening rod 2 through a bearing, and screw holes are correspondingly formed at the positions opposite to the surface of the other group of reinforcement plates 1.

[0031] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the two groups of reinforcement plates 1 can be quickly connected and fixed through the fastening rod 2, so that the loading and unloading efficiency of the warm air duct can be effectively improved. And during the loading and unloading process of the warm air duct, tool-free loading and unloading can also be achieved, reducing the difficulty of loading and unloading the warm air duct.

[0032] The easily installed warm air duct of the present invention, through the cooperation of the reinforcement plate 1, the fastening rod 2, the fixing rod 5, the positioning plate 10 and the fitting plate 7, can not only effectively enhance the structural strength of the connection part of the pipe body 8, but also improve the installation efficiency of the warm air duct. At the same time, through the cooperation of the main mounting plate 6, the auxiliary mounting plate 11, the main sealing layer 3 and the auxiliary sealing layer 12, the sealing performance of the connection part of the warm air duct can be effectively enhanced, reducing the probability of air leakage.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
