DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 5 As shown, a mobile device for teaching English according to the present invention comprises a base 1, a positioning slot 2 is provided at the upper end of the base 1, both sides of the opening of the positioning slot 2 are slidably connected with protective covers 8, the lower ends of the two protective covers 8 are fixedly connected with positioning sliders 12, the positioning sliders 12 are slidably connected to the inside of the positioning slot 2, the upper end of the base 1 is fixedly connected with a vertical plate 3, the outer wall of the vertical plate 3 is provided with a lifting slot 4, the upper end of the vertical plate 3 is fixedly connected with a hydraulic cylinder 5, the piston rod of the hydraulic cylinder 5 passes through the upper end side wall of the lifting slot 4 and the end is fixedly connected with a lifting block 6, the lifting block 6 is slidably connected to the inner upper end of the lifting slot 4, the outer wall of the lifting block 6 is fixedly connected with a display screen 7, and both sides of the lower end of the base 1 are fixed A baffle 15 is fixedly connected, and both sides of the base 1 are rotatably connected with a second rotating plate 13 through a rotating shaft. The lower end of the second rotating plate 13 and the side opposite to the rotating shaft are fixedly connected with a universal wheel 14. The outer wall of the base 1 is symmetrically fixedly connected with a limiting block 20, and both sides of the base 1 are penetrated by a rotating rod 16. Both ends of the rotating rod 16 are sleeved with a fixedly connected limiting plate 17. Both sides of the base 1 are fixedly connected with a sleeve plate 18, and the interior of the sleeve plate 18 is penetrated by a slide plate 19. The slide plate 19 has an L-shaped structure, and the slide plate 19 is against the limiting plate 17. The width of the protruding part of the slide plate 19 is wider than the width of the sleeve plate 18, so that the slide plate 19 can be pulled out and the limiting plate 17 can be pressed against by the slide plate 19 to prevent the limiting plate 17 from rotating.

[0025] Specifically, the internal size of the two protective covers 8 matches the size of the display screen 7, the lower ends of the two protective covers 8 are slidably connected to the upper end of the base 1, and the upper ends of the two protective covers 8 are flush with the lower end of the display screen 7. When in use, the display screen 7 can be supported by the two protective covers 8 to increase the stability of the display screen 7.

[0026] Specifically, the second rotating plate 13 is against the baffle 15, and one side of the second rotating plate 13 on which the universal wheel 14 is installed extends out of the lower end of the base 1, which can occupy an area of ​​the base 1, thereby increasing the stability of the present invention when in use.

[0027] Specifically, the limit plate 17 and the limit block 20 are vertically arranged, and the lower end of the limit plate 17 is flush with the lower end of the second rotating plate 13. The limit plate 17 is against the second rotating plate 13 and the limit block 20 to fix the position of the second rotating plate 13 to prevent the second rotating plate 13 from rotating at will during use.

[0028] Specifically, the cross-sections of the positioning groove 2 and the positioning slide block 12 are both convex structures, and the width of the positioning groove 2 matches the width of the positioning slide block 12, ensuring that the two protective covers 8 are connected to the base 1 without affecting the sliding of the two protective covers 8.

[0029] Specifically, fixed blocks 9 are fixedly connected to the outer walls of the protective cover 8, and the fixed blocks 9 are L-shaped. A first rotating plate 10 is rotatably connected to one of the fixed blocks 9 via a rotating shaft, and a clamping block 11 is fixedly connected to the side of the first rotating plate 10 opposite to the rotating shaft. When the two protective covers 8 are pressed together, the first rotating plate 10 is inserted into the other fixed block 9, so as to facilitate the connection of the two protective covers 8 together.

[0030] Specifically, both ends of the rotating rod 16 are fixedly connected with fixed disks. The diameter of the fixed disks is larger than that of the rotating rod 16 and abuts against the limiting plate 17 , so as to block the limiting plate 17 when in use.

[0031] When moving the present invention, pull the slide plate 19 until the slide plate 19 is separated from the side of the limit plate 17, rotate the limit plate 17, align the limit plate 17 and the limit block 20, rotate the second rotating plate 13, receive the second rotating plate 13 to the lower end of the base 1, and then rotate the limit plate 17 in the opposite direction to block the second rotating plate 13, rotate the first rotating plate 10 180°, pull the two protective covers 8 to move in the opposite direction until they can no longer be pulled, start the hydraulic cylinder 5, and the hydraulic cylinder 5 drives the lifting block 6 to drive the display screen 7 to move downward until it can no longer move downward, and then push the two protective covers 8 together to cover the display screen 7, and rotate back to the original state through the first rotating plate 10. Position, lock the two protective covers 8, and then move the present invention. When the present invention moves to the specified position, rotate the second rotating plate 13 from the lower end of the base 1 until it abuts against the baffle 15, block the second rotating plate 13 by the limit plate 17, and at the same time block the limit plate 17 by the slide plate 19, so that the limit plate 17 cannot rotate, thereby fixing the position of the second rotating plate 13, and then open the two protective covers 8, lift the display screen 7 by the hydraulic cylinder 5, press the two protective covers 8 together, and lock them, support the lower end of the display screen 7 by the two protective covers 8, and ensure the stability of the display screen 7. At this time, the display screen 7 can be started and teaching can begin.
