Description

Technical Field

[0001] The utility model belongs to the technical field of information identification boards, and in particular relates to an electronic information identification board. Background Art

[0002] With the development of society and the rapid development of the electronic information age, in order to bring convenience to people's lives and travel, many roads are equipped with traffic electronic information signs to replace traditional signs. Many maintenance sections are placed with electronic information signs to remind pedestrians or vehicles to pay attention to safety. Since road section maintenance requires constant movement of electronic information signs, existing electronic information signs are inconvenient to move and require multiple people to carry them when moving, which cannot meet the use needs. In addition, the height of existing electronic information signs is inconvenient to adjust and cannot adapt to sections of different heights, and thus cannot clearly display electronic information to people.

[0003] After searching, the Chinese patent authorization announcement number is CN209418050U, which discloses an electronic information sign, including a stable seat, an electronic information sign body is installed on the stable seat, a display is installed on the electronic information sign body, and a PLC controller is electrically connected to the display. A rectangular groove begins at the bottom of the stable seat, and two push rod motors are welded on the top inner wall of the rectangular groove. The output shafts of the two push rod motors are welded with the same push plate, and universal wheels are set at the bottom four corners of the push plate. Two telescopic rods are welded on the top of the stable seat, and the tops of the two telescopic rods are fixedly connected to the bottom of the electronic information sign body. The present invention has a simple structure and is easy to operate. By adjusting the lifting of the universal wheel, the device can be easily moved, saving manpower and increasing the stability of the device when placed. By adjusting the height of the electronic information sign body, it can meet the needs of roads of different heights, and then the electronic information can be clearly displayed to people.

[0004] However, the rising height of the electronic information sign body depends on the length of the motor shaft of the push rod motor, and the length of the motor shaft of the push rod motor is relatively short. Therefore, the rising height of the electronic information sign body is also relatively short, and the height adjustment effect of the electronic information sign body is relatively poor.

[0005] Therefore, we propose an electronic information sign to solve the above problems. Utility Model Content

By using a lead screw motor to drive a lead screw to drive a lifting seat to lift the information sign body upward along a guide post, the height thereof is preliminarily adjusted, solving the problem that the rising height of the sign is limited by the length of the push rod motor shaft. By using a driving motor to drive a synchronous belt through a driving wheel, the installation sliding seat is driven to slide up and down in the limit chute, and the vertical position of the information sign body moving on the frame can be adjusted according to different situations, which can meet the requirements of different height adjustments and reduce the usage limitations of the electronic information sign.

[0011] Preferably, the information sign body is adjusted up and down in height on the frame by driving the synchronous belt by a driving motor to drive through the installation sliding seat.

[0012] Preferably, the lifting seat is driven by a lead screw motor to drive the lead screw to move up and down along the guide post.

[0013] Preferably, an electric control box electrically connected to the lead screw motor and the driving motor is provided at the bottom of the lifting seat.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:
