Description

Technical Field

[0001] The utility model belongs to the technical field of air ducts and relates to a ventilation duct, in particular to a quick-installation factory ventilation duct. Background Art

[0002] Ventilation pipes are hollow pipes used for ventilation, mostly in round or square shapes. The inlet and outlet air ducts of a factory building refer to the pipes used for cooling, ventilation and dust removal in the factory workshop to solve the problem of poor ventilation inside the factory building. At the same time, the setting of the air duct can discharge the water vapor or smoke generated during the production and processing to the outside of the factory building, thereby maintaining a good processing and production environment inside the factory building. The air duct is not quick and convenient to use and connect.

[0003] The connections between existing ventilation ducts are often fixed by bolts. This connection method is not fast and convenient enough and greatly reduces the efficiency of construction. Summary of the invention

[0004] The utility model aims to provide a quick-installation factory ventilation duct in view of the above-mentioned problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a quick-install factory ventilation duct, comprising a duct one and a duct two, characterized in that the front ends of the duct one and the duct two are both provided with positioning protrusions, the rear ends of the duct one and the duct two are both provided with positioning grooves that match the positioning protrusions, a sealing ring is provided between the positioning groove of the duct one and the positioning protrusion of the duct two, the front ends of the duct one and the duct two are both provided with a connecting part one, the rear ends of the duct one and the duct two are both provided with a connecting part two, a connecting column is provided on the connecting part one, a connecting hole for the connecting column to pass through is provided on the connecting part two, a clamping mechanism is provided on the connecting column, a mounting groove for installing the clamping mechanism is provided on the connecting column, and the clamping mechanism is composed of a reset spring and a clamping block.

[0006] In the above-mentioned quick-installation factory ventilation duct, an anti-corrosion layer is provided on the inner walls of the duct one and the duct two.

[0007] In the above-mentioned quick-installation factory ventilation duct, limiting portions are provided on both sides of the clamping block.

[0008] Compared with the prior art, the clamping mechanism provided in the utility model can make it more convenient to install the pipeline. The positioning protrusion, positioning groove and sealing ring can make the connection between the pipelines more sealed. The anti-corrosion layer provided on the inner wall of the pipeline can prevent corrosion to the pipeline caused by long-term discharge of water vapor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, the quick-install factory ventilation duct includes a duct 1 and a duct 2. The front ends of the duct 1 and the duct 2 are both provided with positioning protrusions 3. The rear ends of the duct 1 and the duct 2 are both provided with positioning grooves 4 that match the positioning protrusions 3. A sealing ring 5 is provided between the positioning groove 4 of the duct 1 and the positioning protrusion 3 of the duct 2. The positioning groove 4 and the positioning protrusion 3 can quickly complete the initial fixation. The sealing ring 5 is provided between the protrusion and the groove to improve the sealing performance. The front ends of the duct 1 and the duct 2 are both provided with connecting parts. 1, 6, the rear ends of pipe 1 and pipe 2 are both provided with connecting part 2 7, connecting part 1 6 is provided with connecting column 8, connecting part 2 7 is provided with connecting hole 9 for connecting column 8 to pass through, connecting column 8 is provided with clamping mechanism 10, connecting column 8 is provided with mounting groove 11 for mounting clamping mechanism 10, clamping mechanism 10 is composed of reset spring 12 and clamping block 13, when connecting, clamping block 13 is pressed into mounting groove 11, when clamping device passes through connecting hole 9, reset spring 12 automatically resets without restraint force to complete automatic clamping.

[0014] To elaborate further, an anti-corrosion layer 14 is provided on the inner walls of the pipeline 1 and the pipeline 2 2. The anti-corrosion layer 14 provided on the inner walls of the pipelines can prevent corrosion of the pipelines caused by long-term discharge of water vapor.
