[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6, an educational tool storage box in this embodiment includes a box body 1, a fixed box board 7, a movable box board 8 and a drawer 9, and the drawer 9 is fixedly installed with a T-shaped sliding plate 11 connected to the fixed box board 7 and the movable box board 8 on both sides of the left and right sides, and the movable box board 8 and the fixed box board 7 are provided with a T-shaped groove adapted to the T-shaped sliding plate 11 on the opposite sides. The sliding function of the drawer can be realized by the T-shaped sliding plate 11 and the T-shaped groove. The front side of the drawer 9 is provided with a positioning mechanism 10 extending into the interior thereof and connected to the fixed box board 7 and the movable box board 8. The stability of the drawer can be improved by the positioning structure 10;

[0024] The positioning mechanism 10 includes a second bearing 1001, a second bearing 1001 is fixedly installed inside the front side of the drawer 9, a bearing rod 1002 extending to the outside of the drawer 9 is fixedly connected to the inner wall of the second bearing 1001, a hand wheel 13 is fixedly installed on one end of the front side of the bearing rod 1002 extending out of the outside of the drawer 9, a second gear 1003 is fixedly installed on the rear side of the bearing rod 1002 and located inside the drawer 9, and the second gear 1003 connected to the rear side of the bearing rod 1002 can be driven by rotating the hand wheel 13, and sliding rods 1007 are fixedly installed inside the drawer 9 and at the top and bottom of the second gear 1003, respectively, and the outsides of the two sliding rods 1007 are slidably connected to connecting blocks 1006, and the top and bottom of the second gear 1003 are both meshed with connecting blocks. The second tooth plate 1004 is connected to the block 1006, and the connecting block 1006 uses a sliding rod 1007 to guide and fix the second tooth plate 1004. The separated ends of the two second tooth plates 1004 are fixedly installed with a pin 1005 extending to the outside of the drawer 9 and located inside the movable box plate 8 and the fixed box plate 7. The opposite surfaces of the movable box plate 8 and the fixed box plate 7 are provided with holes adapted to the pin 1005. The second tooth plate 1004 is used to drive the pin 1005 to move, so that the pin 1005 can connect the fixed box plate 7 and the movable box plate 8, thereby improving the stability of the drawer 9. The opposite surfaces of the two second tooth plates 1004 are fixedly installed with a second limit block 1008, which can prevent the second tooth plate 1004 from being detached from the second gear 1003.

[0025] In the case implementation, connecting rods 2 are fixedly installed on the inner bottom of the left and right sides of the box body 1, first bearings 3 are fixedly installed on the outer ends of the two connecting rods 2, first gears 4 are fixedly installed on the outsides of the two first bearings 3, and the tops of the two first gears 4 are meshed and connected with first tooth plates 5 connected to the movable box plate 8. The bottom of the fixed box plate 7 is fixedly connected to the tops of the two first tooth plates 5, and the fixed box plate 7 is located inside the box body 1. The first tooth plate 5 can be moved by rotating the first gear 4, so that the movable box plate 8 and the fixed box plate 7 above the first tooth plate 5 can be moved to the outside of the box body 1, and the first limit blocks 6 are fixedly installed on the bottoms of the opposite surfaces of the two first tooth plates 5 to prevent the first tooth plates 5 from falling off from the first gears 4.

[0026] In the case implementation, a partition 12 is movably installed inside the drawer 9, and the inner walls on the left and right sides of the drawer 9 are provided with multiple slots adapted to the partition 12, and the required space layout can be freely adjusted through the partition 12.

[0027] In the case implementation, the inner bottom wall of the box body 1 is provided with a guide groove adapted to the first limit block 6, so that it has guiding and fixing functions when moving.

[0028] When implementing, follow these steps:

[0029] 1) First, take out the drawer 9 inside the box body 1 through the push-pull groove above the movable box board 8;

[0030] 2) After the drawer 9 is pulled to a suitable distance, the hand wheel 13 on the outside of the drawer 9 is turned to retract the latch 1005 inside the drawer 9 into the drawer 9;

[0031] 3) Pull the hand wheel 13 again to pull out the drawer 9, and use the partition 12 to freely arrange the drawer to place documents or items;

[0032] 4) Finally, push the drawer 9 back to its original position, turn the hand wheel 13, and then insert the internal latch 1005 into the holes in the two side panels, and then push the movable box panels 8 at both ends to close it.

[0033] To sum up, the educational tool storage box, by setting a positioning mechanism 10, rotates the hand wheel 13, drives the bearing rod 1002, and the bearing rod 1002 drives the second gear 1003 to rotate. The second gear 1003 uses the meshing action of the gears to drive the upper and lower second tooth plates 1004 to move, and also drives the two connecting blocks 1006 to move along the sliding rod 1007 to maintain the limiting and fixing effects. The two second tooth plates 1004 will also drive the pins 1005 at both ends to move. The pins 1005 are inserted into the holes on the fixed box plate 7 and the movable box plate 8 to ensure that the drawer 9 has strong stability and connectivity when it is not needed for storage, and the problem of the drawer 9 sliding around will not occur. The lack of a supporting structure for the storage box as a whole is solved. The multi-layer drawer 9 is only fixedly connected by a movable box plate 8, which makes one side of the drawer 9 prone to falling off and damage caused by long-term stress.

[0034] Furthermore, by providing a T-shaped sliding plate 11 and a partition 12, and utilizing the T-shaped sliding plate 11 to movably connect the fixed box plate 7 and the T-shaped grooves on the movable box plate 8, the drawer 9 can realize a pulling and pulling function. By utilizing the card slots and the partition 12 opened inside the drawer 9, the spatial layout inside the drawer 9 can be freely controlled, thereby solving the problem that the patent does not directly adopt any movable structure for the drawer 9 and the movable box plate 8, resulting in a small interval between the upper and lower drawers 9. In actual use, the lower layers of drawers 9 cannot be moved and are inconvenient to take and store.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
