[0012] The utility model provides an educational briefcase, which has the following beneficial effects:
[0013] 1. The utility model installs a storage frame on the outside of the document box, so that office supplies that need to be used urgently can be placed in the storage frame, which is convenient for quickly taking out the office supplies. Then, through the rotatable flap installed on the outside of the storage frame, when emergency work or recording is needed, the flap can be rotated to open, and the flap can drive two sets of rotating connecting rods to rotate along the rotating seat. When the positioning plate at the bottom of the flap is rotated into the positioning seat under the action of the flap, when the flap is rotated ninety degrees, the positioning plate can be rotated into the top of the positioning seat, so that the positioning plate can form a rotation limit effect on the flap, and then effective and stable work can be carried out on the flap, which improves the convenience of using the device.
[0014] 2. The utility model installs a liftable connecting seat on the top of the flap, so that the flap drives the limit rod to move above the limit hole, and the two sets of reset springs release the elastic force to push the two sets of guide slide blocks to move downward, so that the connecting seat drives the limit rod to insert into the limit hole on the storage frame under the action of the two sets of guide slide blocks, thereby quickly forming a steering limit effect on the flap, effectively improving the convenience of the device when used.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0023] The utility model provides a technical solution: Figures 1 to 6 As shown, in the present embodiment, an educational briefcase includes a briefcase body 1, a pull rod 2 is installed on the top of the briefcase body 1, a storage frame 3 is fixed to the outside of the front end of the briefcase body 1, swivel seats 4 are fixed on both sides of the bottom end of the storage frame 3, two groups of swivel seats 4 are rotatably connected with swivel connecting rods 5, flaps 6 are installed on the top of the two groups of swivel connecting rods 5, and a locking structure is provided on the top of the flap 6, a positioning seat 16 is installed at the lower middle part of the storage frame 3, a positioning plate 17 is installed on the outer wall of the bottom middle end of the flap 6, and the positioning plate 17 can be rotatably entered into the positioning seat 16.
[0024] By installing a storage frame 3 on the outside of the document box 1, office supplies that need to be used urgently can be placed in the storage frame 3, which is convenient for quickly taking out the office supplies. Then, through the rotatable flap 6 installed on the outside of the storage frame 3, when emergency work or recording is needed, the flap 6 can be rotated to open, allowing the flap 6 to drive the two sets of rotating connecting rods 5 to rotate along the rotating seat 4. When the positioning plate 17 at the bottom of the flap 6 rotates into the positioning seat 16 under the action of the flap 6, when the flap 6 rotates ninety degrees, the positioning plate 17 can be rotated into the top of the positioning seat 16, and the positioning plate 17 can form a rotation limit effect on the flap 6. Then, effective and stable work can be carried out on the flap 6, thereby improving the convenience of using the device.
[0025] In other embodiments, the locking structure includes a guide slot 7, a guide slider 8, a connecting rod 9, a connecting seat 10, a handle 11, a limit rod 12, a limit hole 13 and a reset spring 14. Two groups of guide slots 7 are provided at the top of the flap 6. Guide sliders 8 are installed in both groups of guide slots 7. The tops of both groups of guide sliders 8 are connected to the connecting seat 10 through the connecting rod 9. A limit rod 12 is installed at the bottom of the rear end of the connecting seat 10. A limit hole 13 is provided at the top of the storage frame 3. The limit rod 12 can be inserted into the limit hole 13 at the top of the storage frame 3. A handle 11 is installed at the top of the connecting seat 10. The outsides of the two groups of guide sliders 8 are both wound with reset springs 14.
[0026] When the cam 12 is in the closed position, the lever 14 is released and the two guide slide blocks 8 are moved upwards, thereby releasing the pull force on the lever 11. When the cam 12 is in the closed position, the lever 12 is released and the two guide slide blocks 8 are moved upwards, thereby releasing the pull force on the lever 11.
[0027] In other embodiments, a storage bag 15 is installed inside the storage frame 3;
