[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: comprising a base 1, an L-shaped plate 9 is fixedly connected to one side of the top of the base 1, a long frame 10 is symmetrically fixedly connected to the inner side of the L-shaped plate 9, and an adjustment mechanism 5 is arranged inside the base 1;

[0023] The adjusting mechanism 5 includes a knob 501, a strip groove 502 is provided on the top of the base 1, and limiting grooves 505 are provided on both sides of the strip groove 502. The strip groove 502 is internally rotatably connected with a screw rod 510, and the external thread of the screw rod 510 is connected with a limiting block 511. The limiting block 511 is slidably connected with the strip groove 502 and the limiting groove 505 respectively. The limiting groove 505 is conducive to limiting the limiting block 511 to prevent it from deflecting. The top of the limiting block 511 is rotatably connected with a rotating block 508. The rotating block 508 The top is fixedly connected with an electronic paper display screen 11, and the bottom of the electronic paper display screen 11 is symmetrically fixedly connected with a support frame 507. A slide groove 504 is provided inside the support frame 507. The inner side of the long frame 10 is rotatably connected with a mounting seat 503. One side of the mounting seat 503 is fixedly connected with a slide rod 506. One end of the slide rod 506 passes through the slide groove 504 and is fixedly connected with a fixing block 509. The fixing block 509 is conducive to fixing the slide rod 506. The end of the screw rod 510 passes through the base 1 and is fixedly connected with a knob 501.

[0024] In this embodiment, by rotating the knob 501 forward, the knob 501 drives the screw rod 510 to rotate, and then the limit block 511 moves inward inside the bar groove 502, and the rotating block 508 rotates on the top of the limit block 511, so that the electronic paper display screen 11 rotates, and the slide bar 506 slides inside the slide groove 504, so that the electronic paper display screen 11 becomes higher. When the knob 501 is rotated backward, the limit block 511 moves outward inside the bar groove 502, and the rotating block 508 rotates on the top of the limit block 511, indirectly lowering the height of the electronic paper display screen 11. The entire device is conducive to adjusting the electronic paper display screen 11 according to a comfortable angle, thereby improving the practicality of the electronic paper display screen 11.

[0025] Furthermore, a plurality of illumination lamps 8 are fixedly connected to the inner side of the top of the L-shaped plate 9, and the illumination lamps 8 are used to illuminate the electronic paper display screen 11. The electronic paper display screen 11 has no brightness without a light source, so at night or when the light source is insufficient, the illumination lamps 8 are needed to supplement the light of the electronic paper display screen 11.

[0026] Furthermore, a light-controlled switch 7 is provided under the base 1, and the light-controlled switch 7 is used to control the switch of the illumination lamp 8 according to the ambient brightness. When the outdoor brightness is not enough, the light-controlled switch 7 will control the illumination lamp 8 to turn on, making it convenient for people to watch the electronic paper display screen 11, and at the same time will not waste electricity.

[0027] Furthermore, an inductive proximity switch 6 is provided below the base 1 and on one side of the light-controlled switch 7. The inductive proximity switch 6 is used to detect whether there is someone on the display surface side of the electronic paper display screen 11 to control the switch of the electronic paper display screen 11. When someone is viewing information, he or she will stand in front of the electronic paper display screen 11, thereby triggering the inductive proximity switch 6 to make the electronic paper display screen 11 display. When no one is there, the electronic paper display screen 11 is in a closed state to prevent waste of electricity.

[0028] Furthermore, a bracket 2 is fixedly connected to the bottom of the base 1 , and a connecting plate 3 is fixedly connected to the bottom of the bracket 2 , which is beneficial for supporting the entire display device.

[0029] Furthermore, screw holes 4 are provided inside the connection plates 3 , and the inside of the screw holes 4 is used in conjunction with screws. By using screws, the connection plates 3 can be fixed to the ground.

[0030] Working principle:

[0031] like Figure 1-Figure 5As shown, when in use, by rotating the knob 501 in the forward direction, the knob 501 drives the screw rod 510 to rotate, and then the limit block 511 moves inward inside the bar groove 502, and the rotating block 508 rotates on the top of the limit block 511, so that the electronic paper display screen 11 rotates, and the sliding bar 506 slides inside the sliding groove 504, so that the electronic paper display screen 11 becomes higher. When the knob 501 is rotated in the reverse direction, the limit block 511 moves outward inside the bar groove 502, and the rotating block 508 rotates on the top of the limit block 511, indirectly lowering the height of the electronic paper display screen 11. The entire device is conducive to adjusting the electronic paper display screen 11 according to a comfortable angle, thereby improving the practicality of the electronic paper display screen 11.
