Description
The utility model relates to multi-functional blackboard.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and the big class of office appliance is write or drawing article, the assistant product group of writing or draw, reusable plate of writing or drawing or tablet technical group field.Be numbered B43L1/04.
At present, the technology about reusable plate of writing or drawing or tablet existing and that once had was all done very fruitful effort to the demand of multi-functional blackboard, also once designed many outstanding technical schemes.As being declared by Sun Lianbao of the Decree of Patent Office of China in 1996, Granted publication number is CN2233324Y, and China Patent No. (ZL) is: No. 95218515.6 utility model title is the utility model patent of " automatic blackboard ", the technical scheme that is adopted.At reusable plate of writing or drawing or tablet technical elements is a routine of great value invention, but it has solved the problem of automatic blackboard effectively.But still have some deficits the problem of the capacity that its also very difficult solution expansion blackboard writing on the blackboard is write.
The purpose of this utility model is to provide a kind of multi-functional blackboard.Solve to enlarge the problem of the capacity that the blackboard writing on the blackboard writes.
The purpose of this utility model is achieved in that this utility model multi-functional blackboard.Mainly constitute by portable plate, top sheave, hook, blackboard body, fovea superior frid, recessed frid, lower sheave, side shield, wall.Its major part blackboard body is a writing board shape, makes material with glass, through the processing and manufacturing of glass flour milling.Its portable plate is a writing board shape, uses the carpentery workshop material, through carpenter's processing and manufacturing.Its top sheave, lower sheave are round-shaped, make material with moulding firmly, through the injection molded processing and manufacturing.The blackboard body of its writing board shape adopts the screw fastening method to be installed on the wall.Structure is write in the writing on the blackboard that forms a writing board shape.The fovea superior frid of its bent plate shape, recessed frid adopt the screw fastening method to be installed on the blackboard body of writing board shape.Form the pulley mobile guide structure of a groove shapes.The portable plate of its writing board shape adopts the hook coupling method to be installed on the round-shaped top sheave.Structure is write in the writing on the blackboard that forms a writing board shape.The side shield of its narrow writing board shape adopts the screw fastening method to be installed on the fovea superior frid of bent plate shape, the recessed frid.What form a writing board shape prevents portable plate landing structure.Its portable plate acts on low groove by lower sheave.Thereby make recessed frid satisfy the support activities plate and move spacing requirement for pulley.Its fovea superior frid, recessed frid act on blackboard body by the screw fastening method.Thereby make it finish task into the pulley mobile guide.So just realized the purpose of this utility model.
The utility model has been compared three advantages and improvement with original reusable plate of writing or drawing or tablet technology;
The first, because the utility model has designed portable plate in technical scheme, so solved the problem that can increase blackboard writing on the blackboard capacity;
The second, because the utility model has designed top sheave and lower sheave in technical scheme, so solved the problem that portable plate can successfully move on blackboard body;
The 3rd, because the utility model has designed side shield in technical scheme, can prevent that portable plate from skidding off the problem that blackboard body drops to the ground so solved.Thereby just can more effectively solve the problem that enlarges the capacity that the blackboard writing on the blackboard writes.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the positive general structure schematic diagram of the utility model multi-functional blackboard;
Fig. 2 is the side sectional structure schematic diagram of the utility model multi-functional blackboard;
Fig. 3 is the pulley part structural representation of the utility model multi-functional blackboard;
The numbering of parts explanation in the schematic diagram: 1 portable plate, 2 top sheaves, 3 hooks, 4 blackboard bodies, 5 fovea superior frids, 6 recessed frid 7 lower sheaves 8 side shields 9 walls
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, the utility model multi-functional blackboard.Mainly constitute by portable plate 1, top sheave 2, hook 3, blackboard body 4, fovea superior frid 5, recessed frid 6, lower sheave 7, side shield 8, wall 9.Its major part blackboard body 4 is writing board shapes, makes material with glass, through the processing and manufacturing of glass flour milling.Its portable plate 1 is a writing board shape, uses the carpentery workshop material, through carpenter's processing and manufacturing.Its top sheave 2, lower sheave 7 are round-shaped, make material with moulding firmly, through the injection molded processing and manufacturing.The blackboard body 4 of its writing board shape adopts the screw fastening method to be installed on the wall 9.Structure is write in the writing on the blackboard that forms a writing board shape.The fovea superior frid 5 of its bent plate shape, recessed frid 6 adopt the screw fastening method to be installed on the blackboard body 4 of writing board shape.Form the pulley mobile guide structure of a groove shapes.The portable plate 1 of its writing board shape adopts the hook coupling method to be installed on the round-shaped top sheave 2.Structure is write in the writing on the blackboard that forms a writing board shape.The side shield 8 of its narrow writing board shape adopts the screw fastening methods to be installed on the fovea superior frid 5, recessed frid 6 of bent plate shape.What form a writing board shape prevents portable plate landing structure.Its portable plate 1 acts on low groove 7 by lower sheave 7.Thereby make recessed frid 6 satisfy support activities plate 1 and move spacing requirement for pulley.Its fovea superior frid 5, recessed frid 6 act on blackboard body 4 by the screw fastening method.Thereby make it finish task into the pulley mobile guide.So just realized the purpose of this utility model.Thereby just can solve the problem that enlarges the capacity that the blackboard writing on the blackboard writes.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in force, if when writing writing on the blackboard in the process of teaching, feels that the capacity of blackboard is little, and can not wipe the writing of finishing writing in the past the time, can use portable plate 1.At this moment can be installed in portable plate 1 on the blackboard body 4 and get final product.Concrete installation method is: earlier top sheave 2 is installed on the portable plate 1 by linking up with 3; Pick up portable plate 1 again top sheave 2 and lower sheave 7 on the portable plate 1 are aimed at, the groove in fovea superior frid 5, the recessed frid 6 gets final product.Like this, under the effect of pulley, portable plate 1 can move on blackboard body 4 automatically.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with glass, wood, plastics, utilize the basic equipment of woodwork processing factory, take injection molded, carpenter's processing method to produce by batch, demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
