Abstract
Based on a dust-free blackboard for magnetophoresis displaying principle, relate to a kind of dust-free blackboard, described blackboard comprises Magnetophoresis display panel, disposable erasing mechanism and selective erase mechanism; Disposable erasing mechanism, the peripheral encirclement with wood frame of Magnetophoresis display panel is fixed, and framework is embedded with the erasing mechanism of guide rail, bearing composition; Its building form is be connected on the long straight guide of underbeam in blackboard main body by rectangular magnet two ends; The erasing mechanism of selective erase, is arranged for interting combine by coiling and bearing, is provided with and wipes control handle synchronized links before magnet and plate after plate.The utility model for displaying principle, with the disposable as a whole erasing mechanism of rectangular magnet, is selective erase mechanism with little magnetic patch after the plate of handrail Complete Synchronization before blackboard with magnetic polymeric imaging, the clear and economic environmental protection of this dust-free blackboard display.
Description
Technical field
The utility model relates to a kind of dust-free blackboard, particularly relates to a kind of dust-free blackboard based on magnetophoresis displaying principle.
Background technology
Along with the quickening of social progress and social rhythm, the sick rate of teaching profession is in the trend risen year by year, and the harm wherein caused by chalk dust is the most serious, as pneumoconiosis, rhinitis chronic, and chronic pharyngitis, pneumonia etc.And the existing dust-free blackboard in market otherwise dust removing effects barely satisfactory, or cost is too expensive, or uses too loaded down with trivial details, could not spread to school classroom on a large scale always.Dust-free blackboard based on magnetophoresis displaying principle is completely dustless, cheap, easy to use, can meet the tight demand of numerous teachers and students to " dustless classroom ".
Summary of the invention
The purpose of this utility model is to provide a kind of dust-free blackboard based on magnetophoresis displaying principle, the utility model with magnetic polymeric imaging for displaying principle, with the disposable as a whole erasing mechanism of rectangular magnet, be selective erase mechanism with little magnetic patch after the plate of handrail Complete Synchronization before blackboard, the clear and economic environmental protection of this dust-free blackboard display.
The purpose of this utility model is achieved through the following technical solutions:
Based on a dust-free blackboard for magnetophoresis displaying principle, described blackboard comprises Magnetophoresis display panel, disposable erasing mechanism and selective erase mechanism; Disposable erasing mechanism, the peripheral encirclement with wood frame of Magnetophoresis display panel is fixed, and framework is embedded with the erasing mechanism of guide rail, bearing composition; Its building form is be connected on the long straight guide of underbeam in blackboard main body by rectangular magnet two ends; The erasing mechanism of selective erase, is arranged for interting combine by coiling and bearing, is provided with and wipes control handle synchronized links before magnet and plate after plate.
Described a kind of dust-free blackboard based on magnetophoresis displaying principle, described selective erase mechanism is connected with arrangement of clutch.
Described a kind of dust-free blackboard based on magnetophoresis displaying principle, described disposable erasing mechanism, being connected with line slideway by magnet is that entirety wipes mechanism.
Described a kind of dust-free blackboard based on magnetophoresis displaying principle, described horizontal direction, crossbearer is provided with line slideway in upper and lower two beams of blackboard main body.
Described a kind of dust-free blackboard based on magnetophoresis displaying principle, described vertical direction, adopts coiling to connect Magnetic eraser.
Described a kind of dust-free blackboard based on magnetophoresis displaying principle, the mode that described arrangement of clutch adopts rack and pinion to combine.
Advantage of the present utility model and effect are:
1. adopt " Magnetophoresis display panel " as blackboard surface first, stopped the possibility of dust completely.That accomplishes truly is dustless.
2. wipe mechanism design ingenious, make its comparatively existing all types blackboard when bulk erase all large for convenience, time saving and energy saving.
3. ferromagnetic material easily obtains, and service time is long, need not additionally buy chalk, blackboard eraser, can reach low-carbon environment-friendly truly, saves economical.While innovation, also reasonably control cost.Reach dustless effect, protect classroom environment and teachers and students' health.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is bulk erase structural scheme of mechanism of the present utility model;
Fig. 3 is selective erase mechanism of the present utility model and arrangement of clutch schematic diagram;
Fig. 4 is winding mode schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is described in further detail.
The utility model, based on Magnetophoresis display panel, coordinates the dust-free blackboard of disposable erasing mechanism and selective erase mechanism.Can the erasing mechanism of disposable erasing, its building form is be connected on the long straight guide of underbeam in blackboard main body by rectangular magnet two ends, can all writings of disposable erasing blackboard when its effect is and horizontally slips.Can realize the erasing mechanism of selective erase, its feature is the interspersed combination by coiling and bearing, can realize moving freely of level and vertical direction, and it is completely synchronous with control handle before plate to wipe magnet after plate.
In Fig. 1, overall structure adopts Magnetophoresis display panel to be main body, and its periphery surrounds fixing with wood frame, framework is embedded with the erasing mechanism of guide rail, bearing composition.
Figure 2 shows that overall wiping mechanism, magnet is connected with line slideway, makes magnet from Magnetophoresis display panel one end to the other end, utilize the magnetic force of whole piece magnet, will words all on board be removed.Thus reaching overall effect of wiping, erase process is convenient and swift.
Figure 3 shows that selective erase mechanism and arrangement of clutch.During owing to writing, magnet is separated with board, and needs magnet and board to be affixed when wiping.
Horizontal direction: as shown in Figure 3, by the line slideway of crossbearer in upper and lower two beams of blackboard main body, reaches moving freely of the horizontal direction of blackboard eraser.
Vertical direction: adopt the method as accompanying drawing 4 coiling to reach the movement of vertical direction, synchronous before and after reaching, determine the position of magnetic patch after plate by mobile blackboard eraser above (in fact play handle effect, real what realize erasing be magnetic patch after plate), thus wipe.
Arrangement of clutch: the mode adopting rack and pinion as shown in Figure 3 to combine, reaches the movement of upright guide rail fore-and-aft direction.When writing, pull-up arrangement of clutch makes it to be separated, and the erasing magnet after plate is also separated with plate, cannot have an impact to magnetic in plate; And when wiping, depress arrangement of clutch, make it laminating, also wipe magnet after making plate and be close to display board, at this moment the magnetic in the erasing attraction plate after plate, from front, namely erasing effect (action of wherein pull-up, pressure arrangement of clutch only can need be realized by the blackboard eraser handle before control panel of whipping) is realized.
