DETAILED DESCRIPTION

[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] like Figure 1-Figure 6 As shown, it includes a device base 1, a storage box 11 is installed on the top of the device base 1, and a folding display part 2 is installed inside the storage box 11 on the top surface of the device base 1. The folding display part 2 includes a motor 21 and a stand 22 fixed on the top of the device base 1, a screw rod 24 is connected to the top shaft of the motor 21, and a lifting plate 25 is connected to the outer thread of the screw rod 24. A slide plate 23 on one side of the lifting plate 25 slides on the inner wall slide of the storage box 11, and display screens 26 are hinged on both sides of the lifting plate 25. When the display screen 26 is stored, it starts to be stuck into the recess opened on the top of the stand 22.

[0025] By designing the storage box 11 and the folding display part 2, the device base 1 is stably placed on the ground when in use, and in the initial state, the display screen 26 is located inside the storage box 11 in a folded storage state, and the bottom of the display screen 26 is stuck in the notch opened on the top of the mounting platform 22 for limiting. When it is exhibited, the motor 21 is started to drive the screw rod 24 to rotate, so that the lifting plate 25 is moved up by the sliding of the slide plate 23, and then the display screen 26 is moved out of the storage box 11, and then the two display screens 26 are rotated and unfolded for use. After use, the display screen 26 is rotated and folded, and then the screw rod 24 is driven to rotate. By rotating in the opposite direction, the display screen 26 can be stored in the storage box 11, and finally the box cover can be closed for dust prevention. During transportation, the display screen 26 can be lifted and transported by the handles designed on both sides of the storage box 11, which is very reliable. The bottom of the display screen 26 is inserted into the recess of the placing platform 22, so that the display screen 26 will not shake and cause bumps during transportation and transfer, thereby effectively solving the problem of poor dust prevention and low transportation safety of the foldable display device in the prior art due to the lack of a better storage structure. It should be noted that the device base 1 can be placed on a transport vehicle for transportation, and the display screen 26 can also be protected by the shell. Figure 2 It can be seen that there are four openings on the top of the storage box 11, so four insertion rods are designed at the bottom of the box cover to be inserted for limiting. This is a prior art method, so it is not described in detail in the figure.

[0026] A sponge pad 27 is bonded into the recess on the top of the placing platform 22 , and the sponge pad 27 is in contact with the outer wall of the display screen 26 .

[0027] Furthermore, the sponge pad 27 can further protect the display screen 26 to prevent the display screen 26 from being damaged due to slight shaking in the recess on the top of the mounting platform 22, which is very practical.

[0028] like Figure 1-Figure 3 as well as Figure 6 As shown, arc plates 12 are installed on both sides of the storage box 11, and circular threaded holes are arranged on the arc plates 12. A threaded hole is also provided at the bottom of the display screen 26. The display screen 26 and the arc plates 12 are fixed by inserting positioning bolts 13 through the threaded holes. The circular threaded holes on the arc plates 12 are evenly distributed along the center of the rotating shaft of the display screen 26. An insert plate 121 is fixed to the outer wall of the arc plate 12. The insert plate 121 and one end of the arc plate 12 are inserted into the slot blocks 14 fixed on both sides of the storage box 11 and fixed by bolts.

[0029] By designing the arc plate 12, the positioning bolts 13, the slot block 14 and the insert plate 121, after the display screen 26 is displayed and used, in order to increase its position stability, the display screen 26 can be rotated to make its bottom threaded hole correspond to the position of a threaded hole on the arc plate 12, and then the positioning bolt 13 can be inserted to fix it, so that the position of the display screen 26 is very firm, which increases the stability of teaching, and the threaded holes on the arc plate 12 are arranged and distributed, and can be adjusted and fixed in multiple positions, which effectively improves the applicability and meets the use requirements of different environments. At the same time, during transportation, due to the large volume of the arc plate 12, the insert plate 121 and the slot block 14 are designed to make the arc plate 12 easy to disassemble, further avoiding collisions during transportation that may cause adverse effects on the display screen 26.

[0030] like Figure 1-Figure 6 As shown, recesses are provided at the bottom ends of both sides of the device base 1, and a stabilizing plate 17 is rotatably connected to the bottom end of the device base 1 at the recess, and the bottom surface of the stabilizing plate 17 is flush with the bottom surface of the device base 1, and a limiting plate 18 is rotatably connected to both sides of the device base 1, and the limiting plate 18 is located on one side of the recess where the stabilizing plate 17 is located, and a door body 15 is hinged on both sides of the storage box 11, and a battery box 16 is installed on the top surface of the device base 1 at the bottom end of the mounting platform 22.

[0031] By designing the stabilizing plate 17, the limiting plate 18, the door body 15 and the battery box 16, and finally optimizing the storage structure, in order to improve the stability of the device base 1 during display, the stabilizing plate 17 can be rotated so that its position is perpendicular to the device base 1, thereby making the stabilizing plate 17 more stable and having a stronger grip. During transportation, the stabilizing plate 17 can be rotated to the inside of the recess of the device base 1, and the stabilizing plate 17 is flush with the side of the device base 1 at this time. Finally, the limiting plate 18 is rotated to limit the stabilizing plate 17 so that it cannot rotate, thereby avoiding the rotation of the stabilizing plate 17 during transportation. The battery box 16 can power the motor 21 or the display screen 26 in some places where it is inconvenient to connect to electricity. At the same time, the opening of the door body 15 is convenient for processing the wires of the battery box 16, the motor 21 and the display screen 26, or for connecting electricity to the battery box 16 for charging, which is very convenient.
