Test box for salt spray corrosion experiment

The utility model belongs to the technical field of salt-spray corrosion experimental equipment, and discloses a test box for salt-spray corrosion experiments, which comprises a test box body, a console is fixedly mounted on the right side of the test box body, an exhaust pipe is fixedly communicated with the top of the back of the test box body, and a box cover is hinged to the top end of the test box body. An observation window body is fixedly installed at the top end of the inner wall of the front face of the box cover. The brush, the connecting spring and the driving motor are arranged, due to operation of the driving motor, the rotating shaft can drive the fixing plate to integrally deflect, then the fixing plate relieves the fixing effect on the movable frame, and at the moment, due to the fact that the connecting spring is in a compressed state, the movable frame and the brush can be pushed to integrally move downwards in an inclined mode. And finally, mist on the lower surface of the observation windo
