Description

Ventilation pipeline structure convenient to assemble and disassemble Technical Field The utility model relates to the technical field of ventilation pipelines, in particular to a ventilation pipeline structure convenient to assemble and disassemble. Background The ventilating duct is a metal or composite pipeline for ventilation and air conditioning engineering of industrial and civil buildings, and is a municipal infrastructure for reducing the concentration of harmful gases in order to circulate air. For example, the fire-fighting ventilation pipeline structure with the authorized bulletin number of 'CN 216557505U', although the existing fire-fighting ventilation pipeline structure is solved, the replacement of a filter screen is more troublesome, a great deal of labor and time cost are required to be consumed, the rotation shaft can be driven to rotate through the driving action of the driving motor, the intermittent rotation of the wind-up roller can be realized by matching with the mutual meshing action of the first gear and the second gear, the intermittent winding action of the wind-up roller on the filter screen is realized, the condition that the existing fire-fighting ventilation pipeline structure is directly installed with the fire-fighting ventilation pipeline and the shed roof by adopting a hanging bracket, the operator is required to step on the distance between the hanging bracket, the nut and the hanging rod to be repeatedly operated, and the disassembly and assembly are inconvenient. Disclosure of utility model The utility model aims to solve the problem that the existing fire-fighting ventilation pipeline structure is inconvenient to disassemble and assemble due to the fact that an operator needs to step up and repeatedly to operate the distance between a hanging frame, a nut and a hanging rod. In order to achieve the purpose, the ventilating duct structure convenient to disassemble and assemble comprises a ventilating duct and fixing holes, wherein the fixing holes are formed in the inner wall of the side end of the ventilating duct, the ventilating duct is fixedly connected with a collecting box through bolts, the inner wall of the collecting box is fixedly connected with a hairbrush, the lower end of the hairbrush is fixedly connected with a rubber strip, and the outer wall of the ventilating duct is connected with a disassembling and assembling mechanism. Preferably, the disassembly and assembly mechanism comprises a square block, the outer wall of the square block is fixedly connected with the ventilating duct, the outer wall of the square block is spliced with the connecting frame, the outer wall of the connecting frame is fixedly connected with the hanging piece, and the outer wall of the hanging piece is spliced with the fixing piece. Preferably, the inner wall of the pendant is propped against the bolt, the outer wall of the bolt is propped against the fixing piece, and the inner wall of the ventilating duct is connected with the cleaning mechanism. Preferably, the cleaning mechanism comprises a U-shaped strip, the outer wall of the U-shaped strip is fixedly connected with the ventilating duct, the outer wall of the U-shaped strip is in sliding connection with the mounting frame, and the filter screen is mounted in the mounting frame. Preferably, the inner wall of the fixing piece is provided with a connecting hole. Preferably, the mounting frame is fixedly connected with the ventilating duct through bolts. The ventilating duct structure convenient to disassemble and assemble has the beneficial effects that after the connecting frame on the ventilating duct is pushed onto the square block to limit the positions of the connecting frame and the ventilating duct, the connecting bolt and the hanging piece are manually controlled to be connected and separated, the ventilating duct can drive the connecting frame and the hanging piece to move left and right, whether the hanging piece can be hooked on the fixing piece or not can be judged, and the hanging piece is connected or separated from the fixing piece, so that the ventilating duct and the ceiling can be quickly disassembled and assembled.
