[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5One end of spring 143 is welded to the vertical plate of guide frame 141, and the other end of spring 143 is welded to movable frame 142.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 An oil injection mechanism 15 is provided at the upper end of the movable plate 7. The oil injection mechanism 15 includes a guide pipe 151. The guide pipe 151 is fixedly connected to the inner wall of the movable plate 7.

[0031] The specific implementation process of this utility model is as follows: In use, the photovoltaic cable can be placed on the support platform at the bottom of the inner side of the test box 1. Under the action of the UV test lamp 10, the photovoltaic cable can be subjected to ultraviolet aging test. Under the extension and retraction of the cylinder 6, the moving plate 7 can be driven to move, thereby driving the support shaft 8 to move, and then driving the rotating frame 9 to move. When the rotating frame 9 moves, it can drive the UV test lamp 10 to move, and adjust the distance between the UV test lamp 10 and the photovoltaic cable.

[0032] The output shaft is driven to rotate by the servo motor 12, which in turn drives the pinion 13 to rotate. Under the meshing relationship, the pinion 13 drives the large gear 11 to rotate, which in turn drives the support shaft 8 to rotate, which in turn drives the rotating frame 9 to rotate, which in turn drives the UV test lamp 10 to rotate, thereby improving the testing efficiency of the UV test lamp 10.

[0033] When the large gear 11 drives the support shaft 8 to rotate, the support shaft 8 can rotate along the surface of the guide plate 144. Under the action of the guide plate 144, the support shaft 8 can be rotated and guided. Under the deformation of the spring 143, the moving frame 142 can be pushed to drive the guide plate 144 to always be in contact with the support shaft 8, so as to ensure a good rotational guiding effect and keep the support shaft 8 in a stable rotational state.

[0034] The electromagnet 158 ​​magnetically attracts the magnetic block 157, causing the magnetic block 157 to move the sealing rod 154. This causes the guide block 155 to slide along the inner wall of the oil reservoir 153, keeping the sealing rod 154 in a stable state. The spring 156 deforms, ultimately causing the sealing rod 154 to detach from the guide hole. Under the guidance and attraction of the guide pipe 151 and the sponge block 152, the lubricating oil can come into contact with the large gear 11 and the small gear 13, lubricating the gears and reducing the problem of hard wear.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
