Description

Technical Field

[0001] The utility model relates to the technical field of signboards, and more specifically, the utility model relates to a signboard that is convenient for loading and unloading. Background Art

[0002] A signboard is an object or board used to mark or indicate specific information, directions, or warnings, usually placed inside and outside public places, buildings, roads, or facilities to help people identify and understand their surrounding environment, thereby providing safety and convenience. Inside the carriages or waiting areas of subways, signboard devices with light-emitting backplates are usually or largely installed. However, in the actual use process, there are still some problems. For example, due to the high air humidity in the underground environment, the text information signboards inside the signboard devices will gradually become blurred under the oxidation of water vapor and oxygen. Therefore, they need to be replaced regularly. However, some signboards are directly pasted on the surface of the carriage or wall with foam glue, resulting in easy damage to the light-emitting backplate or deformation of the peripheral metal frame during replacement. Moreover, during reinstallation, it is necessary to first clean the colloid remaining on the surface of the carriage or wall, resulting in a low working efficiency for actually replacing the signboard. Content of the Utility Model

After that, the staff can draw out the sign from the inside of the metal light box body through the horizontal groove, and after replacement, control the pressing plate to abut against the top of the sign again, thereby reducing the difficulty of replacing the sign and improving the replacement effect.
