Profile assembling structure for composite air pipe connecting flange

Abstract

The invention discloses a profile assembling structure for a composite air pipe connecting flange, and relates to pipe connecting flanges. The profile assembling structure aims to solve the problem that the supporting and reinforcing effect on a composite air pipe is poor. According to the technical scheme, the profile assembling structure for the composite air pipe connecting flange comprises four profiles which are connected end to end to define a rectangular frame structure, connecting structures are arranged between the included angles of the adjacent profiles, each connecting structure comprises an attaching portion and a diagonal supporting portion, the end face of each attaching portion is of a right-angle structure in the front view and is embedded into the inner included angle of the adjacent profiles, the two sections of each attaching portion are attached to the inner walls of the adjacent profiles correspondingly and are provided with self-tapping screws for fixing, each diagonal supporting portion is arranged in the middle of the length direction of the corresponding attaching portion, and the end face of each diagonal supporting portion is straight to support the two sections of the corresponding attaching portion in the front view. According to the profile assembling structure for the composite air pipe connecting flange, assembling is more efficient and convenient, and supporting and reinforcing of the composite air pipe are achieved.

Description

technical field [0001] The invention relates to a takeover flange, more specifically, it relates to a profile assembly structure for a composite air duct takeover flange. Background technique [0002] Composite air duct is an important part of modern indoor purification system. According to the material and functional characteristics, it can be roughly divided into color steel composite air duct, phenolic composite air duct, glass magnesium composite air duct, antibacterial and mildew-proof composite air duct, and double-layer spiral air duct. pipes and stainless steel ducts. [0003] The connecting flange structure is used for the above-mentioned composite air duct to connect two adjacent pipes. In the prior art, its specific structure is as follows: Figure 7 As shown, it includes two end wrapping frames 91 respectively fixed at both ends of the composite air duct, and the four sides of the end wrapping frames 91 are provided with turning edges 92, after the two end wrappi...

AI Technical Summary

Problems solved by technology

[0004] The four profiles of the composite air duct in the prior art are generally fixed to the composite air duct respectively, and then sealed and reinforced with glue to realize the connection into a complete frame structure. Assembled in a passive way, there is a problem of poor support and reinforcement for the composite air duct; therefore, a new solution needs to be proposed to solve this problem
