Description

  The present invention relates to an auxiliary tank mounting device for an air compressor, and more particularly to an auxiliary tank mounting device for an air compressor that can be easily attached to and detached from the air compressor.

  When using pneumatic tools continuously, the tank capacity may be insufficient with only the air tank attached to the air compressor. In such a case, connect a separate auxiliary tank to the air tank of the air compressor with a hose. This can solve the shortage of tank capacity. However, an auxiliary tank separate from the air compressor takes installation space, and the auxiliary tank may become an obstacle at work sites where there is not enough space. In addition, routing of the hose connecting the air tank and the auxiliary tank becomes complicated.

The proposal to reduce the space occupied by the auxiliary tank is to install the auxiliary tank on the vertical frame and place the air compressor in the lower space of this frame, and to install the air compressor in a flat space almost the same as the air compressor alone. Technologies that allow the auxiliary tanks to be installed in an overlapping manner are disclosed (Patent Documents 1 and 2).
