Connecting structure of air duct and ventilation belt and air duct system

Abstract

The invention, which relates to the technical field of ventilation equipment, discloses a connecting structure of an air duct and a ventilation belt and an air duct system. The connecting structure comprises an air duct, a ventilation belt, a fixing piece, an annular soft sleeve and an elastic band. The fixing piece is fixedly connected to the air duct; the fixing piece is connected with the annular soft sleeve; the annular soft sleeve is close to an air opening of the air duct and surrounds the outer side of the air duct, an annular gap for the ventilation belt to penetrate through is reserved between the annular soft sleeve and the outer wall of the air duct, and the elastic band is connected with the annular soft sleeve. When the elastic band is loosened or tensioned, the width of the annular gap can be increased or decreased. According to the connecting structure of the air duct and the ventilation belt and the air duct system, the structure is simple, a worker can conveniently andrapidly disassemble and assemble the ventilation belt on the air duct, and the structure of the ventilation belt cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of ventilation equipment, in particular to a connection structure between an air duct and a ventilation belt and an air duct system. Background technique [0002] In the field of shipbuilding, ventilation equipment is one of the essential equipment. The cross-sectional shape of most fan air duct openings is circular, and the outer periphery of the circular air duct can be sleeved with ventilation belts to realize remote ventilation for areas that cannot be covered by the fan body. Among them, the ventilation belt, also known as the wind tube cloth, is cylindrical in shape and mainly plays the role of guiding wind. [0003] At present, when the construction workers socket the ventilation belt at the air duct opening, they generally use iron wire or rope to fasten the air duct and the ventilation belt. Due to the complex site environment, many cross operations, frequent use of fans, the ventilation belt need...

AI Technical Summary

Problems solved by technology

Due to the complex site environment, many cross operations, frequent use of fans, the ventilation belt needs to be disassembled repeatedly, and the iron wires or ropes wound on the air duct are often missing. As a result, construction workers need to prepare their own iron wires in advance every time the ventilation belt is connected. or string, very inconvenient

Moreover, when fastening with iron wire, it is necessary to tighten it with pliers. The iron wire is easy to get stuck in the hand, and the wind belt is broken, and it is not easy to remove after use.
