Among them, subway information display screens play a role in providing passengers with various information in a timely and accurate manner during subway operation. They display the arrival and departure times of trains in real time, as well as the estimated arrival time of the next train, to help passengers plan their waiting time reasonably. They also present subway route maps and information about the surrounding areas of stations to help passengers understand their travel routes. In the event of emergencies, such as equipment failures or temporary line adjustments, they can quickly issue emergency notices and evacuation guidelines. As an advertising platform, they can display commercial advertisements and other content, which brings economic benefits to subway operation to a certain extent.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3 This utility model provides a technical solution: a city operation information display device, including a front cover 2 disposed on the front side of a rear cover 1, a main board disposed inside the rear cover 1 and the front cover 2, a display module 3 disposed on the front side of the front cover 2, and a backlight disposed on the rear side of the display module 3 and located inside the rear cover 1 and the front cover 2. A locking mechanism 4 is provided at the engagement point of the rear cover 1 and the front cover 2. The locking mechanism 4 consists of a locking block 41, a locking groove 42, symmetrically arranged reinforcing components 43, and symmetrically arranged limiting components 44. The locking block 41 is fixed to the rear side of the front cover 2, the locking groove 42 is opened on the surface of the rear cover 1, the symmetrically arranged reinforcing components 43 are disposed on both sides of the engagement point of the locking block 41 and the locking groove 42, and the symmetrically arranged limiting components 44 are all disposed on the reinforcing components 43. Through the designed reinforcing components 43 and limiting components 44, the original subway information display screen, which was fixed by bolts through the rear cover 1 and the front cover 2 during maintenance, is improved, as it makes disassembly and assembly difficult. A screwdriver is required for installation, but the installation location of the subway information display screen is restricted in all directions, making disassembly and assembly difficult. The reinforcement component 43 and the limiting component 44 secure the rear cover 1 and the front cover 2 through a locking mechanism, allowing for quick disassembly of the front cover 2 without the need for specialized tools, thus improving maintenance efficiency. The surface of the locking block 41 fits snugly against the inner wall of the slot 42. The reinforcement component 43 consists of a groove 431, a spring 432, and a spring block 43. 3. The device consists of a limiting groove 434, a groove 431 formed on the side surface of the card block 41, a limiting groove 434 formed on the inner side of the rear cover 1, a spring block 433 set on the inner side of the groove 431 and the inner side of the limiting groove 434, a spring 432 set on the inner side of the groove 431, and the two ends of the spring 432 are fixed to the bottom end of the groove 431 and the bottom end of the spring block 433, respectively. Heat dissipation components are provided on the inner side of the rear cover 1 and the front cover 2, and interface modules are provided on the inner side of the rear cover 1 and the front cover 2.

[0020] In this embodiment, preferably, the limiting component 44 comprises a rotating groove 441, a rotating block 442, a rotating connector 443, a connecting groove 444, and a guide groove 445. The rotating groove 441 is formed on the side surface of the rear cover 1, the rotating block 442 is disposed inside the rotating groove 441, the guide groove 445 is formed between the rotating groove 441 and the spring block 433 and is located inside the rear cover 1, the connecting groove 444 is formed at the bottom end of the rotating block 442, and the rotating connector 443 is disposed inside the connecting groove 444. The bottom end of the rotating connector 443 is fixed to the top end of the spring block 433. The limiting component 44 is used to limit the block 41 and the slot 42 again after they are engaged by the reinforcing component 43, thereby improving the stability of the fixation. The top surface of the rotating connector 443 is in contact with the inner wall of the connecting groove 444. The rotating connector 443 is a cylindrical structure. The size of the rotating block 442 is matched with the size of the guide groove 445. The length of the guide groove 445 is the same as the diameter of the connecting groove 444.

[0021] The working principle and usage process of this utility model: When the subway information display screen is working, the external device transmits the display content to the display module 3 in the form of digital signals through the interface module. During the working process, the heat dissipation component will work continuously to dissipate the heat generated inside and ensure that the equipment operates within the normal temperature range.

[0022] During the maintenance of the subway information display screen in the urban operation information display equipment, when disassembling the rear cover 1 and the front cover 2, the locking mechanism 4 is operated. By rotating the rotating block 442, the rotating block 442 changes from a parallel state to a vertical state, aligning the rotating block 442 with the guide groove 445. Then, the rotating block 442 is pressed, causing the spring block 433 to be pressed, compressing the spring 432 and causing the locking block 41 to lose its limiting position with the locking groove 42. Then, the rear cover 1 and the front cover 2 can be separated. When the rear cover 1 and the front cover 2 are installed after the maintenance is completed, the rotating block 442 is now in a closed state. 2. When the rotating block 442 is in a vertical state, the rotating connector 443 is inserted into the inner side of the groove 431 by pressing the rotating block 442, and the spring 432 is compressed. Then, the locking block 41 is inserted into the inside of the locking groove 42, and the limiting component 44 and the spring block 433 are inserted into the inner side of the limiting groove 434. The rotating block 442 is released and popped out under the elastic force of the spring 432, so that the spring block 433 is inserted into the inner side of the limiting groove 434. The rotating block 442 passes through the guide groove 445 to the inner side of the rotating groove 441. Then, the rotating block 442 is rotated so that the rotating block 442 in the vertical state becomes parallel.

[0023] 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.
