The invention discloses a structure for testing the brightness of an electro-luminescent sheet, and relates to the technical field of electro-luminescent sheet detection, and the structure comprises a test placement box body, the front side of the test placement box body is provided with a movable door, the top of the test placement box body is provided with a test platform mechanism, and the rear side of the test placement box body is fixedly provided with a test mechanism. The test platform mechanism comprises a rotating motor, the rotating motor is fixedly connected with the bottom of the inner wall of the test placement box body, an output shaft of the rotating motor is fixedly provided with a rotating column, and the top of the rotating column penetrates through the top of the test placement box body and is fixedly provided with a plurality of power supply sockets in an annular array; and a positioning turntable is fixedly mounted on the outer wall of the rotating column. According to the invention, through mutual cooperation of the test platform mechanism and the luminosity detection mechanism, a plurality of cold light sheets can be rapidly and automatically detected one by one after being fixed at the same time, manual one-by-one detection is not needed, and the detection efficiency of the cold light sheets is effectively improved.

This invention discloses a self-heating and cooling permanent magnet motor, comprising a body, an output shaft mounted on the outer wall of the body, and a cover with a clearance fit between the inner wall of the cover and the outer wall of the body. The inner wall of the cover is provided with a first round rod, and the inner walls of two gears are riveted to the outer walls of two second round rods respectively. The outer walls of the two gears are provided with gear rings, and the outer walls of the gear rings are welded to the inner wall of the cover. The top and bottom of the inner walls of the gear rings mesh with the outer walls of the two gears respectively. This self-heating and cooling permanent magnet motor allows the output shaft to rotate when the body is connected to an external power source, through the clearance fit between the groove block and the block, enabling the output shaft to drive the first round rod and the first fan blade to rotate. When the first round rod is in motion, it can also drive the vertical rod and the second round rod to rotate. After reinstallation, the output shaft can still stably drive the first round rod through the engagement of the block and the groove block.

The application discloses a control panel, relates to the technical field of control panels, and comprises a rack, a connecting shell is fixedly connected to one side of the rack, a fixed frame is arranged on one side of the connecting shell, and a control panel is mounted on the inner side of the fixed frame; an unfolding aid; and a tightening sealing element. The unfolding aid is arranged to assist the spring in pushing the rectangular sliding block to move the control panel outward of the connecting shell. When the special-shaped frame is moved out of the connecting shell, the traction spring pulls the rectangular movable block to reset, thereby pulling the fixed frame to move horizontally through the rectangular connecting plate, so that the control panel can be unfolded, the staff can directly see the content displayed on the control panel to maintain and detect the electric elements in the connecting shell, the staff does not need to hold the control panel to watch, the staff maintenance is facilitated, and the practicability of the device as a whole is improved.
