[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] Example 1

[0024] like Figures 1-2 , Figure 4As shown, a drop-proof device for an English learning tablet includes a protective frame 1. The frame 1 encloses a protective cavity 2, where a learning tablet 3 can be placed. A heat dissipation assembly is installed on the protective frame 1, including a mounting groove 4. The mounting groove 4 is located slightly below the cavity of the protective cavity 2. A first mesh plate 5 is installed at the top of the mounting groove 4, and a second mesh plate 6 is installed at the bottom. Fixed seats 7 are symmetrically installed between the first and second mesh plates 5 and 6. A rotating seat 8 is installed on the fixed seat 7, and a fan blade 9 is installed on the seat of the rotating seat 8. A driving device is installed inside the rotating seat 8, which drives the fan blade 9 to rotate. An auxiliary fixing component is installed on the protective frame 1. The frame 1 provides drop protection. The bottom surface of the second mesh plate 6 is higher than the bottom surface of the protective frame 1. Heat dissipation holes are located on the bottom surface of the protective frame 1 below the second mesh plate 6 to ensure effective heat dissipation and facilitate smooth tablet operation.

[0025] During operation, the heat dissipation component is designed so that after the plate is placed inside the protective cavity 2, the plate is placed on top of the second mesh plate 6. When the plate generates a lot of heat during operation, the heat enters the working range of the fan blade 9 through the second mesh plate 6. The drive device inside the rotating seat 8 operates, the fan blade 9 rotates, and with the cooperation of the heat dissipation holes at the bottom of the protective frame 1, the plate is protected while the heat dissipation needs are met.

[0026] Example 2

[0027] like Figures 1-4 As shown, the auxiliary fixing assembly includes a rotating cavity 10. The rotating cavities 10 are symmetrically opened inside the two sides of the protective frame 1. An upper connecting hole 11 is opened through the rotating cavity 10 at a position slightly above the inner wall surface of the protective cavity 2. A lower connecting hole 12 is opened through the rotating cavity 10 at a position slightly below the inner wall surface of the rotating cavity 10 with the upper connecting hole 11. A fixed shaft 13 is fixedly connected inside each rotating cavity 10. A rotating block 14 is rotatably installed on the fixed shaft 13. A structural cavity is opened at the upper part of the rotating block 14. A limit roller 15 is rotatably installed inside the structural cavity. A rubber clamp 16 is attached to the lower part of the rotating block 14. A spring 17 is connected to the vertical structural surface of the rotating block 14 at a position slightly above the limit roller 15. The end of the spring 17 is connected to the inner wall surface of the rotating cavity 10. An anti-slip layer is attached to the working surface of the rubber clamping block 16. When the plate is placed inside the protective cavity 2, the plate first contacts the limiting roller 15 and is then subjected to a squeezing force in the direction of the rotating block 14. The limiting roller 15 is subjected to force and pushes the rotating block 14 to rotate around the fixed shaft 13. The spring 17 is subjected to force and contracts and generates a reaction force, so that the rubber clamping block 16 below the rotating block 14 is tightly clamped on both sides of the plate, achieving the effect of auxiliary clamping and fixing.

[0028] When the spring 17 is not in operation, it does not deform, and the rotating block 14 is in a vertical position at this time.

[0029] When the rotating block 14 is in a vertical position, the working surface of the stationary position of the limiting roller 15 extends beyond the opening space of the upper connecting hole 11, and at this time the clamping structure surface of the rubber clamping block 16 and the vertical inner wall surface of the protective cavity 2 are located in the same vertical plane.

[0030] The protective cavity 2 has symmetrically arranged lifting grooves 18 on the inner walls on both sides of the upper connecting hole 11. A screw 19 is rotatably installed inside one side of the lifting groove 18, and a slide rod 20 is fixed in the opening space on the other side of the lifting groove 18. A support plate 21 is arranged inside the opening cavities on both sides of the lifting groove 18. The two ends of the support plate 21 are respectively sleeved on the outside of the cross sections of the screw 19 and the slide rod 20. When the support plate 21 is not in operation, its plate body is located at the bottom of the lifting groove 18, and at this time, the horizontal plane of the top end face of the support plate 21 coincides with the horizontal plane of the top end face of the first mesh plate 5.

[0031] The top of the cavity in the lifting groove 18, where the screw 19 is installed, has a rotating groove 22. Inside the rotating groove 22 is a actuating piece 23. The top of the screw 19 is inserted into the rotating groove 22 and fixed to the center of the bottom surface of the actuating piece 23. When the flat plate is removed from the protective cavity 2, a actuating force is applied to the actuating piece 23 in the rotating groove 22. The actuating piece 23 rotates, causing the screw 19 to rotate. With the assistance of the sliding rod 20, the pallet 21 moves upward along the lifting groove 18, allowing the flat plate to leave the working range of the limiting roller 15, facilitating the quick removal of the flat plate from the anti-fall device.

[0032] During operation, thanks to the structural design of the auxiliary fixing components, when the flat plate is placed inside the protective cavity 2, it first contacts the limiting roller 15 and is then subjected to a squeezing force in the direction of the rotating block 14. The limiting roller 15 is subjected to force and pushes the rotating block 14 to rotate around the fixed shaft 13. The spring 17 is subjected to force and contracts, generating a reaction force, which makes the rubber clamp 16 below the rotating block 14 tightly clamp the two sides of the flat plate, achieving the effect of auxiliary clamping and fixing, and preventing the flat plate from being ejected when it falls. When the flat plate is removed from the protective cavity 2, a pushing force is applied to the actuating piece 23 in the rotating groove 22. The actuating piece 23 rotates and drives the screw 19 to rotate. With the cooperation of the slide rod 20, the support plate 21 moves upward along the lifting groove 18, so that the flat plate is removed from the working range of the limiting roller 15, which facilitates the quick removal of the flat plate from the anti-fall device.

[0033] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
