Abstract

The utility model relates to a blackboard with a rotary board surface, comprising a frame (1); and two wheel rollers (6) are installed on the frame (1) in parallel, a soft writing panel (4) is wound and sheathed on the two wheel rollers (6), and a motor (5) in transmission connection with one of the wheel rollers (6) is installed on the frame (1). When one surface of the writing panel is used, the wheel rollers can be rotated to be switched into the other surface of the writing panel, thus enlarging the using area of the blackboard. There, the board writing content of the two common blackboard surfaces can be displayed in sequence.

Description

A kind of blackboard of the rotatable space of a whole page
Technical field
The utility model relates to a kind of blackboard as teaching aid.
Background technology
The general structure of existing blackboard is fixed, and can not rotate the space of a whole page, and because the write area of blackboard is less, therefore when after writing full word on the blackboard, needs could continue to write on blackboard through cleaning, and uses inconvenient.On the other hand, have chalk dust during blackboard wiping and fly upward contaminated environment.
The utility model content
Technical problem to be solved in the utility model is, a kind of blackboard of the rotatable space of a whole page is provided, and can increase the usable floor area of blackboard by rotating the space of a whole page, and water cleans blackboard easily, prevents that chalk dust from flying upward.To overcome the defective of existing blackboard.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of blackboard of the rotatable space of a whole page comprises framework, it is characterized in that: parallel on framework two supporting-point rollers are installed, twine on two supporting-point rollers and be socketed with the soft panel of writing, the motor that is in transmission connection with one of them supporting-point roller is installed on framework.
Sparge pipe also is installed on framework, the water jet on the sparge pipe and soft write panel over against; The water storage pump that links to each other with sparge pipe also is installed on framework.
Good effect of the present utility model is:
(1), when write panel wherein one side write finish after, can rotate supporting-point roller and switch to other one side, thereby increase the usable floor area of blackboard.The writing on the blackboard content that can show common two blackboard surfaces successively.(2), interconnected water storage pump and sparge pipe are set, water washes blackboard surface automatically easily, thereby has prevented flying upward of chalk dust.Make the classroom environment clean hygiene.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises framework 1, parallel on framework 1 two supporting-point rollers 6 are installed, on two supporting-point rollers 6, twine and be socketed with the soft panel 4 of writing, on one of them supporting-point roller 6 of framework 1, motor 5 is installed, thereby described motor 5 drives the soft panel 4 of writing together with another supporting-point roller 6 rotations by driving one of them supporting-point roller 6 rotation.On framework 1, also be equipped with near the soft sparge pipe 2 of writing panel 4, the water jet on the sparge pipe 2 and soft write panel 4 over against.Water storage pump 3 is installed on the framework below the sparge pipe 21.
