A PC board anti-aging test device includes a test machine, the outer surface of the test machine is provided with a cabinet, the outer surface of the cabinet is provided with a control cabinet, the lower surface of the control cabinet is provided with a placement cabinet, and the lower surface of the placement cabinet is provided with a test box: the utility model is composed of three major structures of a control cabinet, a placement cabinet, and a test box through the test machine. The placement cabinet and the test box are arranged in the middle of the cabinet. The manual lock on the outer surface of the test box not only plays the role of fixing the door of the test box, but also plays the role of improving the safety during the test. The test machine composed of the above structure solves the defects of large size, difficult installation and disassembly, and inconvenient use. The outer surfaces of the first fixing plate and the second fixing plate are both plugged with fixing screws, and the fixing screws are plugged into the inside of the cabinet to achieve the purpose of firmly fixing the placement cabinet and the test box.

[0004] The above-mentioned existing technical solutions have the following defects: the pulley at the bottom of the testing machine can improve the flexibility of the testing machine's movement, and the adsorption plate enhances the stability of the overall structure, making the testing process safer and smoother. However, the adsorption plate is fixed to the bottom of the testing machine by a support column. Since its height position cannot be adjusted, when the mixing wheel assists the testing machine to move, the adsorption plate is still in contact with the ground, thereby increasing the movement resistance of the testing machine, resulting in a contradiction between the pulley and the adsorption plate. In response to the above situation, technical innovation is carried out on the basis of the existing PC board anti-aging testing device. Utility Model Content
