Abstract
The utility model relates to a rotary blackboard. A board surface is an annular ribbon-shaped soft board surface which is sheathed on two rotatable parallel reel drums; a plain face supporting plate is fixed to the back of a front soft board surface and is adpressed with the back of the soft board surface; the reel drum can drive the rotary elements to be connected mutually. The blackboard can adjust the height of writing contents on the board surface, and can enable writers to choose to write in a range with a small height variation; thereby, physical consumptions are reduced and comfortableness of the writing is enhanced; influences to the sight line caused by obstacles can be reduced after the writing content on the board surface is heightened. The further scheme is that a hair sweeping brush wheel which is arranged on a back board surface can rotate together with the reel drum and can wipe the board surface automatically.
Description
The utility model belongs to a kind of blackboard.
Existing blackboard in use because the height of blackboard fixes, so the writer often needs to cooperate action such as the pin of bending over to remember to write on adapting at various height, and the position of word is when on the low side, the people of back often cannot see word because of influenced by barrier.
The utility model aims to provide a kind ofly can adjust writing position, and can adjust and finish writing the content height, to reduce the swinging blackboard of barrier to the sight line influence.
The technical scheme that realizes above-mentioned purpose is: of the present utility model being characterised in that (referring to implementing illustration): blackboard panel is to be enclosed within the two parallel reels (3) that turn, the endless belt-shaped software plate face (1) on (4), software plate face is divided into preceding software plate face and the back software plate face that lays respectively at the reel both sides, a plane supporting plate (2) is fixed in the back of software plate face before being close to, and described reel links to each other with the parts that can drive its rotation.
Operation principle of the present utility model is: because of being provided with the plane supporting plate behind the preceding software plate face, so can on software plate face, write, when having write a position, can adjust the height of clipboard face by rotating drum, the plate face of having write is raise, and the writer promptly also can write at original height and position.
Plate face written contents height of the present utility model can be adjusted, the writer can be chosen in as required in the little scope of height change and write, thereby reduces physical demands, improves the comfort level of writing, and after plate face written contents heightens, can reduce the influence of barrier.

Embodiment 1
This routine software plate face 1 is enclosed within on the two parallel reels 3,4, and preceding software plate face back is provided with the plane supporting plate 2 of hard, is fixed with manual handle 5 on the reel 4.
Rotate handle 5 with hand and can drive reel 4 and reel 3 rotations, software plate face also rotates thereupon.
A reel 4 of this example is in transmission connection by conveyer belt and manual pulley, and another reel 3 is in transmission connection by the hair brush wheel 7 that conveyer belt and is attached on the software plate face of back.
Below hair brush wheel 7, be provided with an inclined-plane upwards, top edge is attached to scrapes scrubbing brush 8 on the software plate face of back, scrape scrubbing brush inclined-plane below and fix a dust bag 10, back software plate face rear also be provided with one with hair brush wheel 7, scrape scrubbing brush 8, dust bag 10 seal closure 9 inside covering on.
This example in use, with hand rotation manual wheel 11, can drive reel 3,4 rotates, and drive the rotation of circling round together of software plate face, reel 4 drives hair brush wheel 7 rotations that are attached on the software plate face of back again simultaneously, cleans back software plate face, and the writer will not be when will needing the plate face to forward the back to, promptly forwarded to the front by mao back plate face that the brush wheel is cleaned and write fresh content, save time for the writer.
This example is set scrapes scrubbing brush 8 and can scrape off dust on the plate face, and makes dust slip into dust bag along scraping the scrubbing brush inclined-plane, can prevent dust from flying and cover on its outside seal closure.
This routine reel 3 is in transmission connection by driving-belt and motor 12, and motor is in transmission connection by driving-belt and hair brush wheel 7 again.
This example also is provided with an inclined-plane upwards below hair brush wheel 7, top edge is attached to scrapes scrubbing brush 8 on the software plate face of back, scrape scrubbing brush inclined-plane below and fix a dust bag 10, back software plate face rear also be provided with one with hair brush wheel, scrape scrubbing brush, the dust bag seal closure 11 inside covering on.
The writer opens switch and can utilize the driven by motor reel to rotate, and adjusts the plate face, drives a hair brush simultaneously and takes turns plate face after the automatic wiping, has saved Writer's muscle power and time more.
