[0025] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0026] As attached Figure 1 As shown, a teaching aid box with writing function includes a box body 1 and a cover body 2 as well as a positioning member 4 and a fixing screw 5. The box body 1 is a pivotally connected accommodation space for placing teaching aids, and the box body 1 and the cover body 2 are connected by a buckle.

[0027] The structure for connecting the box body 1 and the cover body 2 can be as shown in the attached figure. Figure 2 and 3 As shown, a pivot seat 11 is provided on one side of the opening of the box body 1, and the pivot seat 11 is provided with a pivot slot 102 running through both ends, and the side of the pivot slot 102 facing the inside of the box body 1 is an opening 103. A pivot shaft 21 is provided on one side of the cover body 2. When the cover body 2 is installed on the box body 1, the pivot shaft 21 is adapted to be embedded in the pivot slot 102 along the opening 103. The interface allows the cover body 2 to be pivotally rotated relative to the box body 1, so that the cover body 2 can seal the box body 1. When the cover body 2 is removed from the box body 1, the cover body 2 can be pulled to move the pivot shaft 21 out of the pivot slot 102 along the opening 103, thereby achieving the removal of the cover body 2 relative to the box body 1.

[0028] As attached Figure 4 and 5As shown, one end of the positioning member 4 has a raised positioning portion 41, and the positioning member 4 is provided with a fixing portion 42 and a connecting fixing nut 43 on both sides relative to the positioning portion 41. The fixing screw 5 and the fixing nut 43 are adapted to be spirally connected. The fixing nut 43 is axially fixedly connected and rotates on the side of the positioning member 4. Specifically, the fixing nut 43 and the positioning member 4 can be connected in a manner that a recessed mounting groove (not marked in the drawings) is provided in the positioning member 4 on the other side relative to the fixing portion 42, and a bearing 44 is embedded and fixed in the mounting groove. The end of the fixing nut 43 is provided with a circle of raised connecting portions 431, and the connecting portion 431 is fixedly connected to the inner ring of the bearing 44. The fixed connection method can be direct welding, thereby limiting the fixing nut 43 to rotate only relative to the positioning member 4.

[0029] A clearance hole 401 is provided on the other side of the positioning member 4 relative to the fixing portion 42. The clearance hole 401 is formed by the fixing groove being recessed inward, and is used to form a space after the fixing screw 5 passes through the positioning member 4. That is, after the end of the fixing screw 5 is screwed into the fixing nut 43, the fixing screw 5 can also pass through the clearance hole 401.

[0030] Continue to refer to the attached Figure 3 The cover 2 covers the inner side of the box 1 and is recessed to form a recessed area (not marked in the drawings). The recessed plane of the recessed area is a writing board 22, which can be a whiteboard. The cover 2 is provided with a through slot 201 extending into the recessed area on the end surface of the end pivotally connected to the box 1. Figure 6 and 7 As shown, the positioning portion 41 of the positioning member 4 is adapted to be embedded in the through groove 201 .

[0031] Both sides of the box body 1 are connected to the positioning member 4, and as shown in the attached Figure 2 As shown, both side walls of the box body 1 are provided with recessed embedding grooves 101, and the two embedding grooves 101 are used to connect the two positioning members 4. The specific installation method is shown in Figures 6 to 9 and is as follows:

[0032] The two ends of the fixing screw 5 are respectively screwed together with the fixing nuts 43 of the two positioning members 4, and the two ends of the fixing screw 5 are screwed into the positioning members 4 to such an extent that the distance between the two fixing portions 42 is smaller than the distance between the two sides of the box body 1, so that the two positioning members 4 and the fixing screw 5 can be easily placed into the box body 1;

[0033] Rotate the two fixing nuts 43 separately. During the process, hold the fixing screw 5 with one hand and rotate the fixing nut 43 with the other hand. In this way, the two positioning members 4 are moved relative to the fixing screw 5 until the fixing portions 42 are correspondingly embedded in the embedding grooves 101. Then, continue to rotate the fixing nuts 43 to clamp the positioning members 4 to the side of the box body 1, thereby fixing the positioning member 1 and making the positioning portion 41 face vertically upward.

[0034] Place the writing board 22 of the cover 2 facing away from the box 1, and then place the cover 2 vertically downward on the two positioning members 4, so that the two sides of the through groove 201 are respectively stuck outside the positioning parts 41 of the two positioning members 4, that is, the positioning parts 41 of the two positioning members 4 are correspondingly embedded in the through groove 201, thereby achieving the fixation of the cover 2 vertically relative to the box 1.

[0035] After adopting the above installation method, the cover body 2 serving as the writing board 22 can be fixed on the box body 1 and can be placed on the teacher's desk for direct teaching and explanation, which is very convenient.

[0036] In addition, as attached Figure 1 and 10 As shown, the teaching aid box of the present invention further comprises a net bag 3, which is fixed to the surface of a connecting plate 31. Figure 3 As shown, the recessed area of ​​the cover 2 is recessed inwardly on one side corresponding to the through-slot 201 to form a positioning groove 202. The connecting plate 31 and the net bag 3 are embedded in the recessed area along the through-slot 201, so that the two ends of the connecting plate 31 are respectively embedded in the through-slot 201 and the positioning groove 202. At the same time, after the cover 2 is connected to the box 1, the through-slot 201 can be sealed to prevent the connecting plate 31 from sliding out. This is equivalent to fixing the connecting plate 31 and the net bag 3 in the cover 2 after the cover 2 is connected to the box 1. This structure is conducive to expanding the storage method of the utility model. At the same time, the connecting plate 31 seals the writing board 22, which is conducive to protecting the writing board 22 and preventing it from being scratched when not in use. When the writing board 22 is needed, the cover 2 is removed from the box 1, and the connecting plate 31 and the net bag 3 can be slid out of the through-slot 201.

[0037] In summary, the present invention provides embedding grooves 101 on both sides of the box body 1, for respectively embedding the fixing portions 42 of the two positioning members 4 into the two embedding grooves 101, and screwing the fixing screws 5 and the fixing nuts 43 connected to the two positioning members 4. When the two fixing nuts 43 are rotated toward the sides of the box body 1 where the embedding grooves 101 are provided, the positioning members 4 can be fixed and the positioning portions 41 of the positioning members 4 can be vertically upward. Afterwards, the cover body 2 is vertically downward, so that the two sides of the through groove 201 are respectively stuck outside the positioning portions 41 of the two positioning members 4, and the cover body 2 can be fixed vertically relative to the box body 1, which is equivalent to allowing the writing board 22 to be placed on the teacher's desk, allowing the teacher to write directly and conduct teaching and explanation, which is very convenient.

[0038] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
