Fig. 2 is a side view of the present invention.
Fig. 3 is a front view of the invention when open.
Fig. 4 is a top view of the cover plate structure of the present invention.
In the figure: 1. the blackboard frame 11, the groove 12, the strip-shaped through hole 13, the limiting groove 131, the magnet 2, the board surface 3, the cover plate 31, the limiting bump 311, the iron sheet 32, the connecting rod 33, the placing groove 34 and the clamping groove.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, 2, and 3: a small blackboard for students comprises a blackboard frame 1, a blackboard face 2 and a cover plate 3, wherein a groove 11 matched with the cover plate 3 in structure is formed in the middle of the blackboard frame 1, the blackboard face 2 is fixedly arranged at the groove bottom of the groove 11, strip-shaped through holes 12 are formed in two side walls of the groove 11, a limiting groove 13 is formed in the middle of the upper end of the groove 11, and a magnet 131 is fixedly arranged in the limiting groove 13; the intermediate position fixedly connected with of apron 3 its upper end with spacing groove 13 structure matched with spacing lug 31, spacing lug 31 internal fixed surface is provided with iron sheet 311, 3 both sides face of apron fixed respectively be provided with bar through-hole 12 structure matched with connecting rod 32, connecting rod 32 passes bar through-hole 12 salient in 1 outer end of blackboard frame, blackboard frame 1 and apron 3 its upper end is connected through magnet 131 and iron sheet 311 cooperation, and its both sides end is connected through bar through-hole 12 and connecting rod 32 cooperation.
As shown in fig. 4: the inner surface of the cover plate 3 is provided with a placing groove 33 and a clamping groove 34, the placing groove 33 is located between the limiting lug 31 and the connecting rod 32, chalk and a blackboard eraser can be placed conveniently when the blackboard eraser is used through the placing groove 33, the clamping groove 34 is located at the lower end of the connecting rod 32, and the structure of the clamping groove 34 is matched with that of the lower end face of the blackboard frame 1, so that the blackboard frame 1 is fixed through the clamping groove 34 when the blackboard eraser is used, and shaking of the blackboard frame is avoided.
The lower ends of the two side walls of the groove 11 protrude out of the outer end of the bottom of the groove 11; the bottom end of the strip-shaped through hole 12 is positioned below the groove 11, so that the groove 11 is prevented from influencing the rotation of the cover plate 3 when the cover plate rotates; the iron sheet 311 is smaller than the limiting lug 31 in structure and is located in the middle of the limiting lug 31; the depth of the limiting groove 13 is half of the depth of the groove 11.
In the using process of the invention, firstly, the cover plate 3 is pushed downwards to release the connection between the iron block 311 and the magnet 131, then, the cover plate 3 is continuously pushed downwards, and when the connecting rods 32 on the two side surfaces of the cover plate 3 move to the bottoms of the strip-shaped through holes 12, the cover plate 3 is rotated 90 clockwiseoThe cover plate 3 and the blackboard frame 1 are vertical, finally, the cover plate 3 is used as a base of the blackboard frame 1 and is placed on the desktop, the blackboard frame 1 is pressed downwards, the lower end of the blackboard frame 1 is embedded into the clamping groove 34, the blackboard frame 1 is fixed by the clamping groove 34, and the blackboard frame is prevented from shakingThe problem that students are inconvenient to place when using small blackboards can be solved; in addition, the placing groove 33 is arranged between the limiting convex block 31 and the connecting rod 32, so that the chalk and the blackboard eraser can be placed conveniently when the chalk and blackboard eraser are used, and the convenience in use is improved.
After the blackboard eraser is used and needs to be placed, the blackboard eraser 1 is lifted upwards to disconnect the lower end of the blackboard eraser 1 from the clamping groove 34 on the inner surface of the cover plate 3, and then the cover plate 3 is rotated 90 degrees anticlockwiseoThe cover plate 3 and the blackboard frame 1 are parallel, finally, the cover plate 3 is pushed and pulled upwards along the strip-shaped through hole 12, when the iron block 311 is contacted with the magnet 131, the limit connection of the blackboard frame 1 to the cover plate 3 is completed by utilizing the magnetic attraction effect of the magnet 131 to the iron block 311, and the problem that the use is influenced because the existing small blackboard does not have the protection cover plate 3 and the board 2 is easily damaged and becomes uneven when the existing small blackboard is collided in the placing process is solved by the protection effect of the cover plate 3 to the board 2 in the groove 11 when the blackboard is placed; in general, the invention has the advantages of reasonable structure and convenient use.
Although the present invention has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention.
