Flexible connection structure of air pipes

Abstract

The invention relates to a flexible connection structure of air pipes, which belongs to the technical field of pipeline ventilation facilities. The flexible connection structure of the air pipes comprises a pair of air pipe connection frame bodies and a flexible connector, wherein each air pipe connection frame body comprises four frame bars with the same structure and four angle connectors used for executing the connection of the frame bars; the flexible connector is connected with the air pipe connection frame bodies, and the shapes of the air pipe connection frame bodies are rectangular frame bodies. By the technical scheme, the effect of matching and connecting with air pipe sections can be embodied by connecting a pair of air pipe connection frame bodies with the air pipe sections along with the flexible connector, and a phenomenon that cold or hot air escapes from the air pipes to the outside can not occur, thereby embodying energy saving; the connection with the air pipe sections is convenient and reliable, and binding executed like the prior art is not needed, which is beneficial to lightening the working strength of an erector and is also beneficial to protecting the air pipes.

Description

technical field [0001] The invention belongs to the technical field of duct ventilation facilities, and in particular relates to a flexible connection structure of an air duct. Background technique [0002] In places equipped with central air-conditioning, such as hotels, restaurants, public entertainment places, office spaces, sports venues, exhibition venues and various conference centers, etc., central air-conditioning is usually equipped. In addition, in manufacturers such as manufacturers of electronic and electrical products , paper, textile, pharmaceutical and food manufacturers are also equipped with central air-conditioning. In order to transport air-conditioning or heating to various areas, such as to various rooms in a hotel, it is necessary to use pipes, also known as air ducts. The air duct is divided into several sections, and the adjacent sections are connected by a flexible connection structure. For example, the air duct with a length of 100m is divided into...

AI Technical Summary

Problems solved by technology

The advantages of this kind of flexible connectors made of canvas are simple structure and economical cheapness, but there are the following problems: one is that the sealing is poor, and it is easy to cause air leakage, that is, gas escape, which is not conducive to ensuring the required safety of the place of use. Second, the construction is troublesome, because when binding the flexible canvas and the metal air duct, the labor intensity of the workers is high, and the quality cannot be guaranteed. Even the same constructor cannot guarantee all the bindings. Third, it is easy to damage the air duct, because if the binding is too tight, the air duct will be deformed, and if the binding is too loose, the canvas will come off from the upstream of the air duct
