[0030] The portable teaching aid storage box also includes:

[0031] Auxiliary device 13, the auxiliary device 13 is used to assist in storing teaching aids;

[0032] The outer surface of the sealing cover 3 is slidably connected with a rotating plate 4, the inner surface of the rotating plate 4 is rotatably connected with a fixing rod 5, the inner wall of the box body 1 is fixedly connected with a sliding rail 6, the inner surface of the sliding rail 6 is slidably connected with an L-shaped plate 7, the bottom of the L-shaped plate 7 is fixedly connected with a pushing block 10, the outer surface of the pushing block 10 is slidably connected with a supporting rod 8, the inner surface of the supporting rod 8 is rotatably connected with a fixing block 9, the outer surface of the box body 1 is fixedly connected with a stopper 11, a sliding groove 12 is opened in the wall of the sealing cover 3, the sliding groove 12 corresponds to the sliding rail 6, when the user pulls the L-shaped plate 7 to the outside of the box body 1, the side of the L-shaped plate 7 will slide into the sliding groove 12.

[0033] The outer surface of the fixed block 9 is fixedly connected to the inner wall of the box body 1, the upper surface of the support rod 8 is slidably connected to the bottom of the L-shaped plate 7, the outer surfaces of both sides of the L-shaped plate 7 are slidably connected to the inner surface of the sealing cover 3, the outer surface of the sealing cover 3 contacts the outer surface of the stopper 11, and the sealing cover 3 is pulled. When the sealing cover 3 touches the stopper 11, it no longer rotates. The outer surface of the fixed rod 5 is fixedly connected to the inner surface of the box body 1, and the outer surface of the box body 1 is also slidably connected to the outer surface of the rotating plate 4. The friction between the rotating plate 4 and the fixed rod 5 is large, so that the rotating plate 4 can stop at any position at will, and the rotating plate 4 is rotated around the fixed rod 5 so that the rotating plate 4 is separated from the sealing cover 3, and the sealing cover 3 can be pulled. When the L-shaped plate 7 is pulled outward, the push block 10 at its bottom will rotate the support rod 8 around the fixed block 9 and push it out of the box body 1, thereby supporting the L-shaped plate 7, and the teaching aids stored on the L-shaped plate 7 can be displayed and taken.

[0034] The auxiliary device 13 includes a fixed shell 14, the inner surface of the fixed shell 14 is slidably connected to a sliding cover 15, the inner wall of the sliding cover 15 is fixedly connected to a transparent plate 16, the inner surface of the transparent plate 16 is slidably connected to a partition 17, the bottom end of the partition 17 is fixedly connected to a rotating shaft 18, the outer surface of the rotating shaft 18 is fixedly connected to a turning handle 19, the outer surface of the rotating shaft 18 is fixedly connected to a supporting assembly 20, and scattered teaching aids are supported by the supporting assembly 20 for users to take them conveniently.

[0035] The support assembly 20 includes a support plate 21, a support spring 22 is fixedly connected to the bottom of the support plate 21, a compression spring 23 is fixedly connected to the inner wall of the support plate 21, a slide plate 24 is fixedly connected to one end of the compression spring 23 close to the partition 17, and a ball 25 is rotatably connected to the inner surface of the slide plate 24. The ball 25 can prevent the slide plate 24 from being squeezed at the bottom and immobile due to the large friction force after direct contact with the partition 17. The outer surface of the transparent plate 16 is also fixedly connected to the inner surface of the fixed shell 14, the outer surface of the fixed shell 14 is fixedly connected to the inner surface of the box body 1, the inner surface of the box body 1 is rotatably connected to the outer surface of the rotating shaft 18, the outer surface of the rotating shaft 18 is fixedly connected to the end of the support spring 22 away from the support plate 21, and the inner wall of the support plate 21 is connected to the outer surface of the slide plate 24. The outer surface of the support plate 21 is slidably connected with the inner wall of the fixed shell 14, and the teaching aids are placed on the support plate 21 and the slide plate 24. Due to the gravity of the teaching aids themselves and the pressure of the transparent plate 16 on the teaching aids after the slide cover 15 is closed, the support plate 21 and the slide plate 24 slide down and compress the support spring 22. While the slide plate 24 slides down, it is squeezed by the partition plate 17 to slide inside the support plate 21 and compress the compression spring 23. When taking the teaching aids, the handle 19 can be turned to make the shaft 18 rotate to rotate the teaching aids in the fixed shell 14. When the user observes through the transparent plate 16 that the teaching aids to be taken rotate to the bottom of the slide cover 15, the slide cover 15 is slid to expose the teaching aids. After there is no obstruction from the transparent plate 16, the teaching aids are bounced up by the support spring 22 and the support plate 21, which is convenient for the user to take.

[0036] Working principle:

[0037] When in use, the user rotates the rotating plate 4 around the fixing rod 5 to separate the rotating plate 4 from the sealing cover 3, and can pull the sealing cover 3. When the sealing cover 3 touches the stopper 11, it stops rotating. At this time, the slide groove 12 corresponds to the slide rail 6. When the user pulls the L-shaped plate 7 out of the box body 1, the side of the L-shaped plate 7 will slide into the slide groove 12. When the L-shaped plate 7 is pulled outward, the push block 10 at the bottom will rotate the support rod 8 around the fixing block 9 and push it out of the box body 1, thereby supporting the L-shaped plate 7. The teaching aids stored on the L-shaped plate 7 can be displayed and taken out. When not in use, the teaching aids can be placed on the L-shaped plate 7, and then the L-shaped plate 7 and the support rod 8 are pushed to reset them. After closing the sealing cover 3, the rotating plate 4 is rotated downward, and the sealing cover 3 is prevented from rotating by the rotating plate 4. The friction between the rotating plate 4 and the fixed rod 5 is large, so that the rotating plate 4 can be stopped at any position at will, and the L-shaped plate 7 will not cause the teaching aids to fall into the box body 1 during the movement. The user can lift the box body 1 by holding the drawstring 2.

[0038] When the user takes out the scattered teaching aids in the auxiliary device 13, the user can rotate the handle 19 outside the box body 1 to rotate the shaft 18, and then the partition 17 and the support assembly 20 fixedly connected to the shaft 18 are rotated, that is, the teaching aids placed on the support assembly 20 are rotated in the fixed shell 14. When the user observes through the transparent plate 16 that the teaching aid to be taken rotates to the bottom of the slide cover 15, the user stops rotating the handle 19 and slides the slide cover 15 to expose the teaching aid. After there is no obstruction from the transparent plate 16, the teaching aid is bounced up by the support spring 22 and the support plate 21, which is convenient for The user takes it; when the user puts the scattered teaching aids into the auxiliary device 13, that is, puts the teaching aids on the support plate 21 and the slide plate 24, due to the gravity of the teaching aids themselves and the pressure of the transparent plate 16 on the teaching aids after the sliding cover 15 is closed, the support plate 21 and the slide plate 24 slide down and compress the support spring 22. While the slide plate 24 slides down, it is squeezed by the partition 17 to slide into the inside of the support plate 21 and compress the compression spring 23, and the ball 25 on the side of the slide plate 24 can prevent the slide plate 24 from being squeezed at the bottom and not moving due to the large friction after direct contact with the partition 17.

[0039] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
