AI Technical Summary

Technical Problem

The assembly method of the existing smoke-proof and exhaust duct is connected by multiple sets of bolts, resulting in low assembly efficiency and inconvenient disassembly.

Method used

It adopts the structure of rotating disk, two-way screw rod, screw nut, fixed block, limit splint and guide slide column. The rotating disk drives the two-way screw rod to rotate, and drives the screw nut and fixed block to move in opposite directions. The splint is inserted into the groove on the inside of the convex frame to realize quick assembly and disassembly of the air duct.

Benefits of technology

The rapid assembly and disassembly of the air duct is realized, the assembly efficiency is improved, and the problem of inconvenient assembly methods in the prior art is solved.

Abstract

The utility model relates to the technical field of smoke preventing and discharging air pipes, in particular to an assembly type smoke preventing and discharging air pipe which comprises a first rectangular smoke discharging air pipeline, a rotating disc is arranged on the side face of the first rectangular smoke discharging air pipeline, a two-way rotating lead screw is fixed to the side face of the rotating disc, and the outer wall of the two-way rotating lead screw is connected with a lead screw nut. The lead screw nut is installed in the first fixing rod, a fixing block is installed at one end of the first fixing rod, two sets of limiting clamping plates are fixed to the side face of the fixing block and symmetrically distributed in the first rectangular smoke exhaust air pipeline, and a second fixing rod is installed on the side face, away from the first fixing rod, of the fixing block. A second groove is formed in the inner side of the first rectangular smoke exhaust air pipeline. By operating the rotating disc, the second rectangular convex frame is limited by the two groups of limiting clamping plates, so that the second rectangular smoke and air exhaust pipeline and the first rectangular smoke and air exhaust pipeline are assembled together, and the effect of convenient and fast assembly is achieved.
