The first connecting block 402 is rotatably connected to the hydraulic rod 403. Through the hydraulic principle, the power of the foot pedal 407 is converted into a smooth thrust or pull force to help the door cover assembly 2 to open and close smoothly, ensuring that the hydraulic rod 403 can correctly transmit power. The output end of the hydraulic rod 403 is fixedly connected to the second connecting block 404. The first connecting block 402 and the second connecting block 404 provide connection points for the hydraulic rod 403. The bottom of the second connecting block 404 is fixedly connected to The connecting plate 405 is fixedly connected to the bottom rear side wall of the light box board 1, the pedal groove 5 is internally rotatably connected to a rotating rod 406, one end of the rotating rod 406 is rotatably connected to the bottom end of the transmission connecting rod 401, and a section of the rotating rod 406 away from the transmission connecting rod 401 is fixedly connected to a foot pedal 407, the first connecting block 402 and the hydraulic rod 403, the hydraulic rod 403 and the second connecting block 404, the pedal groove 5 and the rotating rod 406, the rotating rod 406 and the foot pedal 407 are all rotatably connected by fastening bolts, the transmission connecting rod 401, the first connecting block 402, the hydraulic rod 403, the second connecting block 404, the connecting plate 405, the rotating rod 406 and the foot pedal 407 are all arranged at one end of the rear side wall of the light box board 1, and one end of the transmission shaft 203 away from the end of the transmission connecting rod 401 is fixedly connected to a positioning block.

[0034] In actual use, when it is necessary to open or close the door cover of the light box, the user steps on the foot pedal 407, and the foot pedal 407 drives the transmission connecting rod 401 to rotate through the rotating rod 406, thereby driving the transmission shaft 203 to move upward, and the displacement of the transmission shaft 203 drives the cover plate 201 to move through the transmission block 202 and the transmission shaft 203 to realize the opening or closing of the door cover. During the opening or closing process, the matching hook plate 204 cooperates with the rotating hook plate 7 to ensure that the door cover can be stably locked or unlocked. The limit plate 205, the linkage rod 207, the limit block 206 and the limit rod 208 and other components provide additional locking and stability to ensure that the door cover can operate smoothly and safely during the opening or closing process.
