[0002] Electronic information signs are usually electronic or electrical control devices used to display time, temperature or other information. Similar to reading boards and window signs, information can be changed quickly and efficiently. Electronic information signs can display various information in sequence. Many businesses use this sign to release public information and products.

[0003] For example, a Chinese patent discloses: An electronic information identification device, patent number: CN219658134U, which can conveniently move the electronic identifier body downward through a screw rod, thereby avoiding workers from climbing to a high place to disassemble the device, thereby reducing safety hazards.

The outer surfaces of the handle bar 21 and the threaded rod 22 are sleeved with bevel gears 23. The two bevel gears 23 are meshed, and the outer surface of the threaded rod 22 is threadedly connected with a sign body 24. The sign body 24 is slidably connected inside the bracket 11, and the two clamping blocks 17 are slidably connected to the two sides of the sign body 24.

[0029] In view of the problems existing in the prior art, the utility model provides an environmentally friendly electronic information identification device. Before the sign body 24 is lowered, the motor 19 is started, and the output shaft of the motor 19 rotates forward to drive the rotating shaft 13 to rotate. The two worm gears 14 installed on the rotating shaft 13 are installed in opposite directions and have opposite rotation directions. During the rotation of the rotating shaft 13, the two worm gears 14 are engaged to drive the two turbines 15 to rotate inward. The two turbines 15 squeeze the clamping block 17 through the connecting rod 16 to slide to loosen the clamping of the sign body 24.

[0030] Working principle:

[0031] In the first step, the bracket 11 is used to fix and support the sign body 24. By hanging the sign body 24, various information (such as advertising, product introduction, event notification, traffic guidance, etc.) can be displayed to pedestrians in real time to help convey information to the public. When maintenance work needs to be performed on the sign body 24, the handle rod 21 is screwed. During the rotation of the handle rod 21, the two bevel gears 23 are engaged to drive the threaded rod 22 to rotate, and the rotation of the threaded rod 22 drives the sign body 24 to rise and fall. When performing maintenance work, the handle rod 21 can be screwed to lower the sign body 24 for maintenance work. In daily use, the installed photovoltaic solar panel 18 converts sunlight energy into electrical energy as a partial energy source for the sign body 24, which can reduce energy consumption, help save energy and reduce emissions, and achieve environmental protection.

[0032] In the second step, before the sign body 24 is lowered, the motor 19 is started, and the output shaft of the motor 19 rotates forward to drive the rotating shaft 13 to rotate. The two worms 14 installed on the rotating shaft 13 are installed in opposite directions, and their rotation directions are opposite. During the rotation of the rotating shaft 13, the two worms 14 are engaged to drive the two turbines 15 to rotate inward. The two turbines 15 squeeze the clamping block 17 through the connecting rod 16 to slide, so as to loosen the clamping of the sign body 24. When the maintenance work of the sign body 24 is completed, the motor 19 is started, and the output shaft of the motor 19 is reversed to drive the two clamping blocks 17 to slide to clamp and fix the two sides of the sign body 24, thereby improving the sign body 2 4 The stability during installation and placement makes it difficult to shake to avoid affecting the user's perception, which is conducive to improving the stability and reliability of the equipment. When the handle bar 21 is twisted to perform the lifting operation, the ratchet 25 squeezes and pushes the pawl 26 to rotate, and the pawl 26 is driven to reset through the tension spring 27. When the ratchet 25 stops rotating, the pawl 26 contacts the ratchet 25 to limit its rotation direction and limit it. When the lowering operation is required, the pawl 26 needs to be pressed to rotate to perform the reverse operation. The handle bar 21 is limited by the pawl 26 contacting the ratchet 25, so that it is firmly locked in the current position, which is conducive to improving the safety and stability of the lifting operation.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
