Abstract
The invention discloses a drawer type blackboard which comprises a main board and further comprises a sub-board, wherein a chute is formed in each of the upper side and the lower side of the main board, a protrusion is arranged on each of the upper side and the lower side of the bottom end of the sub-board, the protrusions correspond to the chutes, and a pulley which can slide in each chute is fixed at the top end of each protrusion. The drawer type blackboard is simple in structure and convenient to use. At ordinary times, two blackboards are combined, and space can be saved greatly. When the drawer type blackboard needs to be used, only one of the two blackboards needs to be pulled out, and a use area of the drawer type blackboard is enlarged. The drawer type blackboard is convenient to operate and suitable for practical use.
Description
Technical field
The present invention relates to a kind of realia, especially a kind of drawer type blackboard.
Background technology
Blackboard is the necessity in teaching.Existing blackboard is mostly one that fixes, or is embedded in black gypsum fixing in wall, or fixes a plank on the wall.In use, teacher often can write on the blackboard and write the thing of large length, and regular blackboard is not enough, and the thing that writes on the blackboard also needs to continue for Students ' Learning, and at this moment, just very difficult, it is very little very little that teacher just must write font.This awkward situation especially occurs in the explanation of deduce mathematical, etc.All bring great inconvenience for student and teacher, reduced teaching efficiency.
Summary of the invention
For the problem of above-mentioned existence, the purpose of this invention is to provide a kind of drawer type blackboard, two blackboards are combined, can open in case of necessity, become two blackboards.
The objective of the invention is to be achieved through the following technical solutions:
A kind of drawer type blackboard wherein, comprises a mainboard, in the both sides up and down of described mainboard, a chute is arranged respectively; Also comprise a subplate, respectively there is a projection both sides, up and down, bottom of described subplate, and described projection is corresponding with described chute; Respectively be fixed with a pulley that can slide in described chute on the top of described projection.
Above-mentioned a kind of drawer type blackboard, wherein, described subplate length scale is less than the length scale of described mainboard.
Above-mentioned a kind of drawer type blackboard, wherein, the width of described projection is less than or equal to the width of described chute.
Above-mentioned a kind of drawer type blackboard, wherein, described pulley and described projection are fixed together in the mode of screw.
Above-mentioned a kind of drawer type blackboard, wherein, described mainboard is cuboid.
Compared with the prior art, beneficial effect of the present invention is: simple in structure, easy to use, at ordinary times, two blackboards are combined, and can greatly save the space like this; When needs use, only need to extract another piece blackboard out and get final product, strengthened the blackboard usable floor area.Easy to operate, be suitable for practicality.
Description of drawings
Fig. 1 is the structural representation of a kind of drawer type blackboard of the present invention.
The specific embodiment
The invention will be further described below in conjunction with schematic diagram and concrete operations embodiment.
As shown in Figure 1, a kind of drawer type blackboard of the present invention comprises a mainboard 1, respectively has in the both sides up and down of mainboard 1 in a chute 21,31(figure not indicate); Also comprise a subplate 4, both sides, up and down, the bottom of subplate 4 respectively have in a projection 22,32(figure indicate), wherein, projection 21 is corresponding with chute 22, protruding 31 is corresponding with chute 32; In respectively being fixed with a pulley 23 that can slide, 33(figure in chute 31 and chute 32, the top of projection 22,32 do not indicate).
In enforcement, the width of projection 21 and projection 31 is less than the width of chute 22 and chute 23, pulley 23 and pulley 33 are arranged on guide rail groove 21 and 31 outsides along the horizontal direction with guide rail groove 21 and 31, make pulley 23 and pulley 33 to be free to slide in chute 22 and chute 23.
In another embodiment, the width of projection 21 and projection 31 is greater than the width of chute 22 and chute 23, pulley 23 and pulley 33 horizontal direction along guide rail groove 21 and 31 is arranged in guide rail groove 21 and 31, makes mixed opinion 23 and pulley 33 to be free to slide along chute 22 and chute 23.
In enforcement, can adopt variety of way that pulley 23 and pulley 33 are fixed on guide rail groove 21 and 31, for example, adopt the mode of screw, with the two ends of pulley 23 and the non-two ends of guide rail groove 21 and the two ends of guide rail groove 31 of not being fixed on, two ends of pulley 33.
In enforcement, as required, can make the subplate 4 of different length size, for example, subplate 4 can be less than mainboard 1, also can be with mainboard 1 equal in length, can also be longer than mainboard 1.
In addition, according to self-demand, mainboard 1 and subplate 4 can be made into different formation, for example, cuboid, square, etc.
Above specific embodiments of the invention are described in detail, but the present invention is not restricted to specific embodiment described above, it is just as example.To those skilled in the art, any to this equivalent modifications of carrying out and alternative also all among category of the present invention.Therefore, not breaking away from impartial conversion and the modification of having done under the spirit and scope of the present invention, all should contain within the scope of the invention.
