Abstract
The utility model relates to a blackboard for writing capable of circularly rotating. The utility model is characterized in that a piece of annular cloth for a blackboard is sheathed on the periphery of an active rotating shaft and a passive rotating shaft; the active rotating shaft is driven by a driver to rotate, driving the annular cloth for the blackboard rotate circularly, so the writing board surface can move; the back of part of the annular cloth for the blackboard is provided with a supporting pad plate, the cloth which is moved to the position of the pad plate can be written on, so that all people can write on suitable positions whether the people are short or tall, people can not easily feel fatigue, and the face of the blackboard can be increased by one time, compared with the mounting face.
Description
The utility model relates to a kind of writing blackboard, particularly Jiao Xue writing blackboard.
Be widely used in the blackboard of imparting knowledge to students now, modal is fixedly black-board of horizontal-scroll-type.For enlarging the clipboard face, also have up and down or left and right sides Push-pull blackboard.The fixed-site of this class blackboard.Because to have height to have short for Writer's health, for making full use of limited clipboard face, just must bend over or stretch one's legs and write, make the writer be easy to generate fatigue.
The purpose of this utility model is that a kind of rotating writing blackboard device capable of circulation will be provided, no matter the height that it can writer's health all can be write like a cork in optimal position.And can nearly double in the clipboard face of erection space.
The purpose of this utility model is achieved in that
Annular blackboard cloth (5) is enclosed within on the periphery of active rotating shaft (6) and passive rotating shaft (2).Annular blackboard cloth (5) is local to cushion by supporting backing plate (4) support, makes annular blackboard cloth (5) can realize writing.When driver (8) ordered about active rotating shaft (6) and does clockwise direction and rotate by driving-chain (7), this moved towards last supporting backing plate (4) to drive annular blackboard cloth (5), and passive rotating shaft (2) is rotated.So just constituted the realization of rotating writing blackboard capable of circulation.
Accompanying drawing is embodiment of the present utility model.Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is a structure drawing of device of the present utility model.
As shown in the figure, articulated stand (3) makes cover passive rotating shaft (2) thereon can rotate and can move up and down around fulcrum.Fixed support (9) grip active rotating shaft (6) location is thereon lived, and active rotating shaft (6) can only be rotated, and is not movable.Annular blackboard cloth (5) is enclosed within on active rotating shaft (6) and passive rotating shaft (2) periphery.Since active rotating shaft (6) the sixth of the twelve Earthly Branches the location, fixedly on the wall, the other end hooks articulated stand (3) to extension spring (1) one end, and passive rotating shaft (2) is moved up, until straining annular blackboard cloth (5).Annular blackboard cloth (5) part that is tightened up abuts against to be supported on the backing plate (4), supports backing plate (4) and is fixed on the wall.Driver (8) provides gyration, by driving-chain (7), drives active rotating shaft (6) revolution.Active rotating shaft (6) is revolution clockwise, also makes annular blackboard cloth (5) abut against the one side that supports on the backing plate (4) and moves up, and another side moves down.Abutting against the part of supporting the annular blackboard cloth (5) on the backing plate (4) can realize writing.
Write the part annular blackboard cloth (5) that is over and move up, can then write again, write full until monoblock annular blackboard cloth (5).Wipe repeated use then.So promptly realize rotating writing blackboard capable of circulation.
Claims (2)
1, a kind of device of rotating writing blackboard capable of circulation, this device includes on the periphery that an annular blackboard cloth (5) is enclosed within active rotating shaft (6) and passive rotating shaft (2), passive rotating shaft (2) is installed on the articulated stand (3), active rotating shaft (6) is installed on the fixed support (9), the part of annular blackboard cloth (5) has support backing plate (4) support to cushion, active rotating shaft (6) links to each other with driver (8) by driving-chain (7), it is characterized in that driver (8) drives active rotating shaft (6) rotation, is overlapping annular blackboard cloth (5) in active rotating shaft (6) and the passive rotating shaft (2).
2, device according to claim 1 is characterized in that annular blackboard cloth (5) is enclosed within on the periphery of active rotating shaft (6) and passive rotating shaft (2).
