Description
Technical field
The utility model relates to a kind of improvement of blackboard structure.
Background technology
Blackboard is the indispensable educational aid of school instruction.At present, the technology about blackboard existing and that once had is improved blackboard and has been made very fruitful effort, also once designs many outstanding technical schemes.As being declared by He Yicong of the Decree of Patent Office of China in 2011, application number is: No. 201020583946.2 utility model, title are the utility model patents of " blackboard ", the technical scheme that is adopted.At the technical elements of blackboard, be of great value innovation and creation, it has effectively solved the slow problem that erases the board by the mode of the microscler blackboard eraser identical with the blackboard height is set on blackboard.But it still exists deficiency; As: it can not rotate, and can't make the classmate of the left and right sides all can see blackboard clearly, also can't solve the not problem of easy-clear of the interior chalk dust of blackboard groove, and in addition, it can't regulate height.
Summary of the invention
The utility model is exactly at the problems referred to above, and the Convenient blackboard of a kind of simple in structure, rotatable, adjustable-height and easy cleaning ledge for chalk on blackboard is provided.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises blackboard, its structural feature is: described blackboard rear side is provided with framework, blackboard links to each other by the vertical rotating shaft that is provided with between the two with framework, the both sides of blackboard are provided with cushion block, and cushion block links to each other by cotton rope with blackboard; The framework surface is provided with end slipway, and the rear side of blackboard is provided with and the corresponding slide block of end slipway, and the side of framework, at least one side are provided with and the corresponding fixture of blackboard; One side of blackboard lower end is provided with axle, and the blackboard groove flexibly connects by described axle mutually with blackboard, and the opposite side of blackboard lower end is provided with and the corresponding block of blackboard groove.
Described fixture comprises fixed block, and fixed block is provided with the lead screw of passing fixed block.
As a kind of preferred version, described vertical rotating shaft is arranged on blackboard rear side middle part; Be arranged on vertical rotating shaft 12 at blackboard 5 middle parts, the angle of upset equates about can making.
The beneficial effects of the utility model:
1, simple in structure
The utility model comprises that mainly blackboard, framework, fixture and blackboard groove constitute; Member is few, and is therefore, simple in structure.
2, conveniently allow the classmate of the left and right sides all see blackboard
Because the utility model blackboard links to each other by the vertical rotating shaft that is provided with between the two with framework, the both sides of blackboard are provided with cushion block; After teacher has write writing on the blackboard, earlier blackboard is gone to the left side by rotating shaft, the cushion block on blackboard right side is inserted between blackboard and the framework, with this fixing blackboard, Zuo Ce classmate just can clearly see the emphasis that teacher writes clearly like this; And then same blackboard is gone to the right side; Can make things convenient for the classmate to look at the blackboard like this.
3, can regulate the blackboard height
The utility model framework surface is provided with end slipway, and the rear side of blackboard is provided with and the corresponding slide block of end slipway, and the side of framework, at least one side are provided with and the corresponding fixture of blackboard; During use, promote blackboard at first up and down, cooperate, the position adjustments of blackboard to the height that is fit to, is fixed blackboard with fixture then, used blackboard with regard to the user who makes things convenient for different heights like this by slideway and slide block.
4, the chalk dust in the easy cleaning blackboard groove
One side of the utility model blackboard lower end is provided with axle, and the blackboard groove flexibly connects by described axle mutually with blackboard, and the opposite side of blackboard lower end is provided with and the corresponding block of blackboard groove; When needing the chalk dust in the cleaning blackboard groove, at first the blackboard groove is taken off from block, by the axially rotation down of opposite side, it is just very convenient to clear up chalk dust so then.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1 be the blackboard groove, 2 for block, 3 for cushion block, 4 for cotton rope, 5 for blackboard, 6 for fixture, 7 for lead screw, 8 for fixed block, 9 for framework, 10 for slide block, 11 for end slipway, 12 for vertical rotating shaft, 13 for the axle.
The specific embodiment
The utility model comprises blackboard 5, and described blackboard 5 rear sides are provided with framework 9, and blackboard 5 links to each other by the vertical rotating shaft 12 that is provided with between the two with framework 9, and the both sides of blackboard 5 are provided with cushion block 3, and cushion block 3 links to each other by cotton rope 4 with blackboard 5; Framework 9 surfaces are provided with end slipway 11, and the rear side of blackboard 5 is provided with and end slipway 11 corresponding slide blocks 10, and the side of framework 9, at least one side are provided with and blackboard 5 corresponding fixtures 6; One side of blackboard 5 lower ends is provided with axle 13, and blackboard groove 1 flexibly connects by described axle 13 mutually with blackboard 5, and the opposite side of blackboard 5 lower ends is provided with and blackboard groove 1 corresponding block 2.
Described fixture 6 comprises fixed block 8, and fixed block 8 is provided with the lead screw 7 of passing fixed block 8.
