A back panel 100b is provided on the side of the box profile 100a away from the hinge assembly 300, and a sealing gasket 100c is provided between the box profile 100a and the back panel 100b. The sealing gasket 100c is used to seal the connection between the box profile 100a and the back panel 100b, which helps to reduce the humidity in the light box and ensure the service life of the light box.

[0089] In this embodiment, the electromagnetic lock 500 can be controlled to close via the handle assembly 520. For example, the handle portion 522 can be rotated to rotate the hand shaft, which in turn drives the transmission plate 525 to move, thereby switching the lock body 510 and the fixing buckle 530 between the closed and open states, making it easier to remove the cover shell for replacement and maintenance of the light box. The reflective identification 526 is used to distinguish the closed and open states of the lock body 510 and the fixing buckle 530. For example, the reflective identification 526 can be alternately provided with red and green colors. By rotating the hand shaft, the red color is revealed on the electromagnetic lock 500, and the lock body 510 and the fixing buckle 530 are in the closed state. Alternatively, by rotating the hand shaft, the green color is revealed on the electromagnetic lock 500, and the lock body 510 and the fixing buckle 530 are in the open state.

[0090] In summary, the present application discloses a subway light box, which includes a light box body, a light box cover, a hinge assembly, an elastic pad, and an electromagnetic lock. The light box cover is connected to the light box body, the hinge assembly is connected to the light box body and the light box cover, the elastic pad is located between the light box body and the light box cover, the electromagnetic lock is provided on the light box cover, and the light box cover has a first locked state and a second open state through the electromagnetic lock. The present application meets the use environment and safety standards, has a reasonable and simple structure, low production cost, easy disassembly and assembly, and a high level of protection. The electromagnetic lock can be controlled by a handle, so that the cover shell can be easily removed for replacement and maintenance of the light box. The elastic pad has a buffering effect, which can reduce the impact between the light box cover and the light box body, thereby ensuring that the light box cover will not be deformed during long-term use, thereby further improving the service life of the light box.

[0091] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
