An air duct rigid anti-seismic support system

Abstract

The invention provides a rigid anti-seismic support system for an air duct, which includes a casing, a support frame, a bottom rod, a top rod, a fixing seat, a semicircular guide rail, an arc-shaped connecting frame, a connecting rod, a telescopic rod assembly and a transmission rod, and the two casings pass through Hinged together, there are four bottom rods inside the shell, and a push rod is installed in the bottom rod, and a fixed seat is installed at the end of the push rod. The end of the shell is provided with a semicircular guide rail, and the semicircular guide rail An arc-shaped connecting frame is installed movable inside, and the arc-shaped connecting frame is connected with the ejector rod through connecting rods and rotatably respectively. The rigid contact with the air pipe is achieved by combining the two shells and under the action of the support frame, which ensures the anti-seismic effect, and the clamping of the air pipe is realized by rotating the arc-shaped connecting frame to drive the top rod to move along the bottom rod. The end of the fixed seat is rotatably connected with the push rod, so the contact angle can be adjusted when it contacts the air duct, so it can be clamped when facing a square or round air duct.

Description

technical field [0001] The invention relates to the technical field of anti-seismic connectors, in particular to a rigid anti-seismic support system for air ducts. Background technique [0002] Publication No. CN206904368U provides a double-lateral anti-seismic support device for rectangular air ducts. The metal frame is straightened by cable-stayed channel steel, thereby ensuring the rigid anti-seismic effect, and the above-mentioned prior art is only for rectangular air ducts. support, and air ducts are divided into square and circular, so the adaptability of the above-mentioned prior art is relatively poor, and only rectangular air ducts are anti-seismic installed. Contents of the invention [0003] The purpose of the present invention is to provide a rigid anti-seismic support system for air ducts to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solut...
