DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] In order to make the objects, technical solutions and advantages of the invention more clearly understood, the technical solutions in the embodiments of the invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. The components of embodiments of the invention generally described and illustrated in the drawings herein may be arranged and designed in a wide variety of different configurations.

[0024] As is shown in drawings, a multifunctional blackboard comprises a table top 1 and a | blackboard 2, wherein table legs 3 are provided at the four corners of the bottom of said table top 1, and fixing plates 4 are arranged between said table legs 3; the top surface of said table top 1 is provided with bar-shaped holes 5, and at the position that is at the bottom of said table top 1 and is corresponding to said bar-shaped holes 5 are fixed with a check bracket 6, which is hollow, and the long edge, which is away from said table top 1 thereof is provided with a

BL-5192 LU102437 through hole 7; two sides of said through hole 7 are fixedly connected with springs 8, and the other side of said springs 8 are fixedly connected with a pulling plate 9; the side of said pulling plate 9 that is close to said through hole 7 is arranged with a positioning post 10, which is inside said through hole 7; the side of said check bracket 6 that is away from said through hole 7 is vertically fixed with a slideway 11;

[0025] Said blackboard 2 is arranged within said check bracket 6; two sides of said blackboard 2 are provided with sliding blocks 12, which is arranged within said slideway 11; the bottom of said blackboard 2 that is close to said through hole 7 is arranged with a groove 13 for being used in conjunction with said positioning post 10.

[0026] Preferably, the thickness and width of the blackboard 2 are matched with the inner diameter of said check bracket 6 and said bar-shaped holes 5.

[0027] Preferably, when the spring 8 is in an unstressed state, the positioning post 10 passes through said through hole 7.

[0028] Preferably, said slidway 11 and said sliding block 12 are used together.

[0029] Preferably, said bar-shaped hole 5 is located at the edge of the top surface of said table top 1.

[0030] Preferably, said fixing plates 4 are arranged in a cross shape. |

[0031] Using method and principle

[0032] When the blackboard is used, the blackboard 2 slides upwards along the Slideway 11 via the sliding block 12, the top of the blackboard 2 penetrates through the check bracket 6 and the bar-shaped hole 5 on the tabletop 1 until the position of the groove 13 at the bottom of the blackboard 2 is matched with that of the positioning post 10, then the pulling plate 9 is pulled outwards by hand, the position of the groove 13 is moved to correspond to the through hole 7, after the pulling plate 9 is loosened, the positioning post 10 is arranged in the groove 13 under the action of the spring 8, and then the blackboard 2 is fixed and used for teaching

BL-5192 LU102437 and demonstration;

[0033] when the blackboard 2 is not needed, or the device needs to be moved and transported, the blackboard 2 needs to be collected, the pulling plate 9 is pulled at the moment, the positioning post 10 is moved out of the groove 13, the blackboard 2 can slide downwards through the sliding block 12 and the slideway 11, and therefore the storage of the blackboard 2 is achieved.

[0034] The invention combines the blackboard and the teaching desk to achieve multifunctional use. The blackboard can realize the lifting function, which can not only use the teaching desk alone, but also use the teaching desk and the blackboard together. It is suitable for teaching and demonstration in flexible situations, easy to move, and novel and complete in structure.
