Technical Field

[0001] This utility model relates to the field of signage technology, and in particular to a signage device that can be replaced online while powered on. Background Technology

[0002] A directional sign is a sign that indicates direction; it's also called a billboard or signpost. Examples include restroom signs and road signs. Its definition is quite broad. Examples include lobby signs in hotels and guesthouses. Directional signs can be placed near companies to help people quickly find them; roadside signs to guide people to different routes; and in real estate developments to help people understand the location of the property. They are also found at gas stations, along highways, and in hotels—in many places. Current signs often include powered displays to attract more people and improve visibility, especially at night or on cloudy days. However, existing signs are connected by wires, meaning that if one sign is damaged, the power must be switched off, causing the displays on the remaining signs to malfunction. Furthermore, the signs are bolted in place, making disassembly inconvenient. Therefore, we propose a sign replacement device that allows for live, online replacement. Utility Model Content

[0013] 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.

[0014] Example: Refer to Figures 1-5 A sign replacement device that can be powered on and replaced online includes a fixed frame 1, two support frames 7 are fixedly installed at the bottom of the fixed frame 1, and further includes: The storage cavity 11 is located inside the fixed frame 1. Several rollers 2 are rotatably installed at the bottom of the fixed frame 1. An antistatic layer 3 is provided inside the fixed frame 1 and on the rollers 2. An insulating layer 4 is sleeved inside the antistatic layer 3. A protective shell 5 is sleeved inside the insulating layer 4. A display screen 6 is fixedly installed inside the protective shell 5. A battery is provided inside the fixed frame 1. The battery is connected to a charging head 16 through a wire 17. One end of the charging head 16 passes through the top of the fixed frame 1, the antistatic layer 3, the insulating layer 4 and the protective shell 5 and is plugged into a socket on the display screen 6. A limiting component is located within the fixed frame 1 and is used to limit the antistatic layer 3.

[0015] The limiting components include: The limiting groove 12 is opened at the top of the storage cavity 11, and a stop 13 is slidably installed in the limiting groove 12. A pull post 15 is fixedly installed on the top of the stop 13 and located in the limiting groove 12, and the upper end of the pull post 15 passes through the top of the limiting groove 12 and extends to the outside. Spring 14 is sleeved on pull column 15 and located in limit groove 12.

[0016] In this technical solution, when a person pulls the pull column 15, the stop block 13 moves upward within the limiting groove 12. Simultaneously, the stop block 13 compresses the spring 14 to retract until one side of the stop block 13 no longer contacts the antistatic layer 3. At this point, the person can remove the antistatic layer 3, the insulating layer 4, the protective shell 5, and the display screen 6 from the storage cavity 11. Furthermore, the display screen 6 is more easily removed by the left and right support of the rollers 2. When the repaired display screen 6 is placed into the storage cavity 11, the antistatic layer 3, the insulating layer 4, the protective shell 5, and the display screen 6 are placed within the storage cavity 11. Roller 2 pushes the antistatic layer 3, which in turn presses against the stop block 13, causing the stop block 13 to move upward within the limiting groove 12. Simultaneously, the stop block 13 compresses the spring 14, causing it to contract. The antistatic layer 3 then fully enters the receiving cavity 11. When the antistatic layer 3 is located on one side of the stop block 13, the spring 14 extends and presses the stop block 13 downward within the limiting groove 12, blocking the antistatic layer 3. This ensures the structural stability of the antistatic layer 3, insulation layer 4, protective shell 5, and display screen 6, and facilitates the disassembly and installation of the display screen 6 by personnel.

[0017] The pull column 15 is slidably connected to the limiting groove 12, and the two ends of the spring 14 are tightly welded to the stop block 13 and the top of the limiting groove 12, respectively.

[0018] In this technical solution, it is ensured that the pull column 15 can move normally within the limiting groove 12, and the structure of the spring 14 and the stop block 13 is guaranteed to be stable.

[0019] One side of the block 13 is in contact with the antistatic layer 3, and the side of the block 13 away from the antistatic layer 3 is inclined.

[0020] In this technical solution, when the antistatic layer 3, the insulating layer 4, the protective shell 5 and the display screen 6 are placed on the roller 2 in the storage cavity 11, the antistatic layer 3 is pushed, and the antistatic layer 3 will squeeze the stop block 13, causing the stop block 13 to move upward in the limiting groove 12. At the same time, the stop block 13 will squeeze the spring 14 to retract, so that the display screen 6 can be easily put into the storage cavity 11.

[0021] The antistatic layer 3 is slidably connected to the storage cavity 11.

[0022] In this technical solution, the antistatic layer 3 is ensured to slide within the storage cavity 11.

[0023] The fixed frame 1 and the support frame 7 are integrally formed structures.

[0024] In this technical solution, the structural stability of the fixed frame 1 and the support frame 7 is ensured.

[0025] In this technical solution, when the display screen 6 is removed from the storage cavity 11 for maintenance, the charging head 16 needs to be pulled out from the top of the fixing frame 1, the anti-static layer 3, the insulating layer 4 and the protective shell 5, as well as the socket on the display screen 6. Each fixing frame 1 contains a battery, ensuring that even if the main power needs to be turned off when a single sign is damaged, the undamaged display screen 6 can be replenished with power by the battery in the fixing frame 1 and can be used normally.

[0026] When in use: When removing the display screen 6 from the storage cavity 11 for maintenance, the personnel manually pull the charging head 16 out from the top of the fixing frame 1, the anti-static layer 3, the insulating layer 4 and the protective shell 5, as well as the socket on the display screen 6. Each fixing frame 1 contains a battery. Even if the main power needs to be turned off when a single sign is damaged, the undamaged display screen 6 can be replenished with power by the battery in the fixing frame 1 and can be used normally. Subsequently, pulling the pull column 15 causes the stop block 13 to move upward within the limiting groove 12. Simultaneously, the stop block 13 compresses the spring 14, causing it to contract until one side of the stop block 13 no longer contacts the antistatic layer 3. At this point, the antistatic layer 3, insulation layer 4, protective shell 5, and display screen 6 can be removed from the storage cavity 11. The presence of several rollers 2 on the left and right makes it easier to remove the display screen 6. When the repaired display screen 6 is placed back into the storage cavity 11, the rollers inside the storage cavity 11 are used to... 2. Push the antistatic layer 3, which will squeeze the stop block 13, causing the stop block 13 to move upward within the limiting groove 12. At the same time, the stop block 13 will squeeze the spring 14 to contract, and the antistatic layer 3 will be completely inserted into the receiving cavity 11. When the antistatic layer 3 is located on one side of the stop block 13, under the rebound extension of the spring 14, the spring 14 will squeeze the stop block 13 to move downward within the limiting groove 12 and block the antistatic layer 3, ensuring the structural stability of the antistatic layer 3, the insulating layer 4, the protective shell 5 and the display screen 6, and ensuring that personnel can easily disassemble and install the display screen 6.
