The second support rod 307, together with the positioning posts 308, can support the first support rod 303, thereby improving the stability of the rotation angle of the first support rod 303 and the stability of the support for the children's drawing board body 1. The protective shell 2 is fixedly connected to the inside of the limiting strip 309. The limiting strip 309 can contact the bottom of the children's drawing board body 1, thereby preventing the children's drawing board body 1 from sliding during the tilting process and improving the stability of the placement. The positioning posts 308 are snapped into the inside of the limiting hole 305, and the auxiliary groove 304 is adapted to the shape of the second support rod 307.

[0019] In the support assembly 3, the reset shaft 302, due to its internal torsion spring structure, can automatically reset after rotating within the storage groove 301. The support rod 303 on its side surface rotates with the reset shaft 302, and after rotation, it can support the children's drawing board body 1. The auxiliary groove 304 inside the support rod 303 is used to store the support rod 307. The support rod 307 rotates within the storage groove 301 via the rotating shaft 306.

The limiting strip 309 inside the protective shell 2 contacts the bottom of the children's drawing board body 1 to prevent it from sliding when placed at an angle.

[0020] In this invention, the protective shell 2 provides protection by covering the children's drawing board body 1. Combined with the handle 4, it effectively improves portability. The simple structure allows children to easily place the drawing board inside a backpack or other container. In the support assembly 3, the reset pivot 302 allows the first support rod 303 to automatically reset and be stored. The second support rod 307, in conjunction with the positioning post 308 and the limiting hole 305, allows for adjustment of the placement angle of the children's drawing board body 1. The limiting strip 309 enhances placement stability. Overall, the device improves its ease of use and flexibility, thus making it convenient for children to carry the children's drawing board anywhere for use.

[0021] Specifically, such as Figure 3 and Figure 6 As shown, the movable structure includes a pair of limiting slide grooves 101 formed on the side of the children's drawing board body 1, and each pair of limiting slide grooves 101 has a positioning groove 102 formed on its inner wall; the movable structure also includes a pair of limiting slide strips 201 fixedly connected to the inner wall of the protective shell 2, the limiting slide strips 201 are slidably connected inside the limiting slide grooves 101, and can limit the sliding of the protective shell 2, the limiting slide strips 201 are fitted with positioning blocks 202 adapted to the positioning grooves 102 through a reset structure inside the limiting slide strips 201; the positioning blocks 202 are snapped into the positioning grooves 102, and can position the installation of the protective shell 2, so as to prevent the device from becoming loose during carrying.

[0022] In the movable structure, the limiting groove 101 on the side of the children's drawing board body 1 slides and engages with the limiting strip 201 inside the protective shell 2, restricting the movement direction of the protective shell 2; the positioning block 202 installed inside the limiting strip 201 through the reset structure can be engaged into the positioning groove 102 on the inner wall of the limiting groove 101 under the action of the reset structure, thereby positioning the position of the protective shell 2.

[0023] In this invention, the sliding cooperation between the limiting slide groove 101 and the limiting slide strip 201 ensures that the protective shell 2 moves smoothly and its direction is controllable; the snap-fit ​​between the positioning block 202 and the positioning groove 102 can effectively fix the position of the protective shell 2, prevent loosening during carrying, and ensure the stability and reliability of the structure.

[0024] Specifically, such as Figure 6 As shown, the reset structure includes a telescopic groove 2021 formed inside the limiting slide 201. The telescopic groove 2021 is T-shaped and is adapted to the limiting block 2023 on which the limiting block 2023 is installed. The positioning block 202 is slidably connected inside the telescopic groove 2021. The limiting block 2023 is fixedly connected to the side of the positioning block 202. The limiting block 2023 can limit the positioning block 202 installed inside the telescopic groove 2021. A helical spring 2022 is fixedly connected between the positioning block 202 and the telescopic groove 2021. The helical spring 2022 can reset the positioning block 202 by telescopic movement.

[0025] In the reset structure, the positioning block 202 is slidably connected in the T-shaped telescopic groove 2021 inside the limiting slide bar 201, and the limiting block 2023 on its side is adapted to the telescopic groove 2021 to prevent the positioning block 202 from detaching from the telescopic groove 2021; the helical spring 2022 between the positioning block 202 and the telescopic groove 2021 is in a compressed state, providing elastic force to the positioning block 202, so that it automatically resets and is locked into the positioning groove 102 when it is not subjected to external force.

[0026] In this utility model, the helical spring 2022 realizes the automatic reset function of the positioning block 202, and the positioning can be completed without manual operation, which simplifies the fixing process of the protective shell 2; the limiting block 2023 prevents the positioning block 202 from disengaging from the telescopic groove 2021, ensuring the reliability of the reset structure and further improving the ease of use of the device.

[0027] Specifically, such as Figure 1 As shown, a support pad 5 is fixedly connected to the top of the protective shell 2. The support pad 5 is made of rubber. The rubber support pad 5 can increase the friction with the placement surface, thereby playing a role in preventing slippage.

[0028] Working principle and usage process of this utility model: When staff carry the device, the protective shell 2 is covered on the outside of the children's drawing board body 1 through the movable structure. At this time, the limiting slide 201 is slidably connected in the limiting slide groove 101, and the positioning block 202 pops out from the telescopic groove 2021 and is locked into the positioning groove 102 under the elastic force of the spiral spring 2022, so as to realize the positioning and fixation of the protective shell 2 and prevent it from loosening when carrying. Staff can easily pick it up and carry it through the handle 4. The protective shell 2 effectively protects the children's drawing board body 1. When needed, the staff moves the protective shell 2, at which point the positioning block 202 is subjected to force, causing it to compress the spiral spring 2022 and retract into the telescopic groove 2021. After the positioning is released, the protective shell 2 slides and detaches from the children's drawing board body 1. Then the staff can place the protective shell 2 with the opening facing up and the support pad 5 facing down, and then place the children's drawing board body 1 on top of the protective shell 2. The limiting strip 309 inside the protective shell 2 contacts the bottom of the children's drawing board body 1 to prevent slippage. Then, the support rod 303 is rotated outward from the storage slot 301, the torsion spring inside the rotating shaft 302 is reset to deform under force, and the support rod 307 stored in the auxiliary slot 304 is rotated out through the rotating shaft 306. The positioning post 308 on its side is inserted into the corresponding limiting hole 305 on the support rod 303, thereby fixing the support angle of the support rod 303, so that the children's drawing board body 1 is placed at the required angle. The rubber support pad 5 on the top of the protective shell 2 increases the friction with the placement surface to achieve anti-slip. After use, the staff pulls out the positioning column 308, retracts the second support rod 307 into the auxiliary slot 304, and the reset shaft 302, under the action of the torsion spring, drives the first support rod 303 to automatically reset and be stored in the storage slot 301. Then, the protective shell 2 slides to cover the children's drawing board body 1 again. The positioning block 202 is first compressed, and then automatically snaps into the positioning slot 102 under the action of the spiral spring 2022 to complete the fixation. The device can then be carried again by the handle 4.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
