Background

"electronic information" is a word frequently appearing in recent years, and is a word that becomes informatics in the context of rapid development of computer technology, communication technology, and high-density storage technology and widespread use in various fields. The electronic information fundamentally breaks the universe of storing and transmitting information by paper carriers for a long time in the aspects of information storage, transmission and application, and represents the development direction of the information industry.

At present, a plurality of storefront doorways have electronic information display screens, the electronic information screens are expensive and fragile in texture, and when the electronic information cards are not used, the electronic information cards lack protection and are easy to be damaged, so that huge economic loss is brought to users.

Disclosure of Invention

The purpose of the invention is: the electronic information display device is used for solving the problems that a display screen of the existing electronic display device is lack of protection and is easy to be damaged when not used.

In order to achieve the technical purpose, the technical scheme adopted by the invention is as follows:

an electronic information display device comprises a display screen, wherein a frame is arranged at the edge of the display screen, supporting legs are arranged at two sides below the frame, an L-shaped baffle is hinged to two sides of the frame, hinged blocks are arranged at the two side edges of the rear end face of the frame and correspond to the L-shaped baffle, notches matched with the hinged blocks are formed in the L-shaped baffle, a through hole is formed in each hinged block, a first rotating shaft penetrates through the through hole and is fixedly connected with the L-shaped baffle, the L-shaped baffle is hinged to the hinged blocks through the first rotating shaft, a first helical gear is mounted at the top end of the first rotating shaft, a second helical gear is meshed above the frame and is meshed with the inner side of the first helical gear, a spur gear is arranged on the inner side of the second helical gear, a support frame is mounted on the inner side of the spur gear, and, the frame top is equipped with the shape of falling U pull rod, a fixed section of thick bamboo is respectively installed at the frame in the shape of falling U pull rod both ends, the both ends of the shape of falling U pull rod are inserted respectively and are established in the fixed section of thick bamboo that corresponds, it has the fixed block to be close to spur gear one side still fixed mounting on the shape of falling U pull rod, fixed block free end fixed mounting has the rack, rack and spur gear meshing.

Further limiting, first supporting blocks are arranged on two sides of the rear end face of the lower portion of the frame, second supporting blocks are arranged on the lower portion of the L-shaped baffle, and the cross sections of the first supporting blocks and the second supporting blocks are in a right trapezoid shape. Such structural design is rotatory behind the display screen back to L shape baffle, inclines display device backward, makes the inclined plane and the ground contact of the lower extreme of first supporting shoe and second supporting shoe, supports display device for display device can place more steadily when using.

Further inject, two fixed mounting has the spliced pole between the first braced block. Such structural design is upwards pulling the shape of falling U pull rod for when L shape baffle shifts the display screen rear from display screen the place ahead, can step on the spliced pole with the foot, avoid display device to leave ground, it is more convenient to use.

Further limited, the side wall of the fixed cylinder is provided with a threaded hole, a butterfly bolt is screwed in the threaded hole, and the side wall of the inverted U-shaped pull rod is radially provided with a first fixing hole and a second fixing hole which are matched with the threaded hole. According to the structural design, after the inverted U-shaped pull rod is pressed to the limit, the L-shaped baffle is positioned in front of the display screen, the position of the first fixing hole corresponds to the threaded hole, the butterfly bolt is screwed down and inserted into the first fixing hole, the inverted U-shaped pull rod and the fixing barrel are fixed together, at the moment, the display device is inclined forwards, the roller is in contact with the ground, the inverted U-shaped pull rod can be used for dragging the display device, and the use is more convenient; meanwhile, the positions of the L-shaped baffles are fixed and can not rotate any more, so that the two L-shaped baffles are prevented from being opened accidentally when the display device is moved; after the inverted U-shaped pull rod is pulled up to the limit, the L-shaped baffle is located behind the display screen, the position of the second fixing hole corresponds to the threaded hole, the butterfly bolt is inserted into the second fixing hole after being screwed down, and the inverted U-shaped pull rod and the fixing barrel are fixed together, so that the L-shaped baffle is fixed and can not rotate, and the display device is stably supported.

Further limiting, a groove is formed in the lower portion of the front end face of the supporting leg, and a roller is installed in the groove.
