Description

CONDUIT FOR CONVEYING HARMFUL GASES A WORK STATION}

The present invention relates to a pipe for transferring harmful gas generated in an industrial or non-industrial workplace, and more particularly, to a tube for transferring harmful gas to a filter or the like.

When welding works in the industrial field, the gas harmful to the human body is generated by the melting of the welded object and the welding rod, and the gas harmful to the human body is generated even when cooking in a non-industrial restaurant. Since these harmful gases adversely affect the health of workers as well as those around them, they must be transported to a place far away from the workplace immediately after being discharged, or transferred to a filter and filtered before being supplied again to the workplace. .

When the working position is fixed when transferring harmful gas from the workplace to the outside of the workplace or to the filter, the gas can be transferred by installing a hood on the upper part of the working position and connecting the gas pipe to the hood. In the case of a workplace where the position is changed, in order to move the hood to the upper part of the working position, the hood and the pipe must be connected to each other so that the angle can be changed. It can be done.

In order to connect the hood and the pipe so that the angle can be changed and to adjust the inclination angle of the pipe, the conventionally provided technology connects two pipe members to each other by a bellows type flexible member and a lifting and lowering bracket. The member is connected to the hood by the flexible member and rotary bracket as described above, and the other tube member is connected to the rotary tube by the flexible member and the elevating rotation bracket as described above. In order to connect, what connected the flange so that rotation was possible is provided.

However, the lifting pivot bracket in the pipe for transporting the harmful gas as described above is insufficient in consideration of durability, so a problem arises that the fixed position of the pipe cannot be maintained firmly after using the pipe. Since the bracket is exposed to the outside of the hood, it hinders work and of course, the appearance is not beautiful.

The present invention is to provide a pipe for transporting the harmful gas generated from the workplace is very excellent in durability and beautiful appearance while maintaining the inclined state and the fixed position of the pipe in consideration of the conventional problems as described above. It is a task.
