DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] like Figure 1-Figure 5 As shown, the adjustable bracket of a tablet learning machine proposed in this embodiment includes a support 1, a rectangular bracket, an angle adjustment component, three sets of length adjustment components and four guards 3.

[0027] A plurality of suction cups 5 are installed at the bottom end of the support 1, the rectangular bracket is rotatably installed on the support 1, the angle adjustment component is installed on the rectangular bracket for adjusting its inclination angle, the bottom end of the rectangular bracket is connected with a rotating connecting plate 9, a fixed seat 10 is installed on the support 1, and the rotating connecting plate 9 is rotatably installed on the fixed seat 10.

[0028] The rectangular bracket includes four groups of telescopic parts. Two adjacent groups of telescopic parts are fixedly connected. The four groups of telescopic parts form a rectangular structure. The telescopic parts include a sleeve a201 and two movable rods a202. The ends of the two movable rods a202 are respectively slidably installed on the inner ends of the sleeve a201.

[0029] One set of length adjustment components is connected between the two sets of telescopic parts on the upper and lower sides, and the other two sets of length adjustment components are connected to the two sides of the movable rod b42 in the transverse direction and are respectively connected to the two sets of telescopic parts on the left and right sides. The length adjustment components include a sleeve b41, a movable rod b42 and a positioning member. The end of the movable rod b42 is slidably installed on the inner side of the sleeve b41. The movable rod b42 has a hollow structure. The positioning member includes a mounting plate 12, a wedge block 13, a guide rod 14 and a spring 15. The guide rod 14 is arranged on the inner side of the movable rod b42, the mounting plate 12 is slidably arranged on the guide rod 14, the spring 15 is sleeved and installed on the guide rod 14, the wedge block 13 is installed on the mounting plate 12, the movable rod b42 is provided with a through hole 421 for the mounting plate 12 to pass through, and the sleeve b41 is provided with a plurality of positioning holes 411 side by side.

[0030] The four guards 3 are respectively installed at the four corners of the rectangular bracket. The guards 3 include an L-shaped corner guard 31, an L-shaped front stop 32 and a rubber pad 11. The L-shaped front stop 32 is arranged on the front side of the L-shaped corner guard 31, and the rubber pad 11 is installed on the inner side of the L-shaped corner guard 31.

[0031] A fan mounting bracket 17 is installed on the sleeve b41, and a fan 7 is installed on the fan mounting bracket 17. Starting the fan 7 can accelerate the heat dissipation of the learning machine.

[0032] When installing the learning machine, place the learning machine on the inner side of the rectangular bracket, and then push the two telescopic parts on the left and right sides to move inward at the same time (or push the two telescopic parts on the upper and lower sides to move first). The movement of the telescopic parts drives the movable rod b42 to move inward. During this process, the inclined surface of the wedge block 13 contacts the sleeve b41 to force the wedge block 13 to move inward. When the wedge block 13 moves to the position of the next positioning hole 411, the wedge block 13 is driven to be stuck in the corresponding positioning hole 411 under the elastic force of the spring 15. Through the setting of the length adjustment component, the movable rod b42 can be restricted to move only toward the inner side of the sleeve b41. When the left and right sides of the learning machine are limited, the two telescopic parts on the upper and lower sides are simultaneously squeezed inward in the above manner until the upper and lower sides of the learning machine are limited; when the learning machine is disassembled again, the wedge block 13 is squeezed inward to move it out of the corresponding positioning hole 411, and then the movable rod b42 is pulled outward, and then the remaining two length adjustment components are adjusted in the above manner so that the four guards are separated from the learning machine.

[0033] Embodiment 2

[0034] like Figure 2 As shown, the present embodiment proposes an adjustable bracket of a tablet learning machine. Compared with the first embodiment, in the present embodiment, the angle adjustment component includes a rotating rod 6, a rotating seat 8 and a limit plug 16. The two ends of the rotating rod 6 are rotatably connected to the rectangular bracket and the rotating seat 8 respectively. The limit plug 16 is arranged at the bottom end of the rotating seat 8. A plurality of positioning grooves 101 matching the limit plug 16 are arranged side by side on the support 1. Through the arrangement of the above-mentioned structure, the multi-angle adjustment of the learning machine can be realized, and the angle between the rectangular bracket and the support 1 can be adjusted to more than 90 degrees, and the applicability is strong.

[0035] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
