Description
Technical field:
The utility model relates to a kind of teaching aid, particularly relates to the special blackboard eraser of a kind of blank.
Background technology:
Teaching aid comprises the routine and professional teaching aid that middle and primary schools' basic education and large, all kinds of specialized education of special secondary school use.Generally there is material object, objective things are directly presented in face of student, so that student's direct feeling; Object simulating, comprises sample, model and other duplicate, as tellurion, manikin, engineering equipment model etc.; Describe the chart of things image, comprise various visualization chart such as picture, photo, map and statistics, design etc.; Reproduce the sophisticated equipment of things image and process thereof, as projector, television set, recorder, video recorder, slide projector, projecting apparatus etc.The conventional teaching aid used when giving lessons in addition, as blackboard, blackboard eraser, blank, chalk etc.
As the one of common teaching aid, blank is the writing plane of usually white metallic sheet material.Effect and the blackboard of blank are similar, are a kind of writing implements that can be repeatedly erasable.Be generally used for teaching, session discussing, or individual and family keep record.
Along with the application category of blank is more and more extensive, in the application of blank, say that the problem appeared in one's mind is also just more and more, such as, because blank itself is not with blackboard eraser, proviso is wrongly write and found blackboard eraser when Xu needs to carry out erase operation is a troublesome process, is inconvenient to manage.Simultaneously because blank is write by lettering pen often, blackboard eraser needs to change in use for some time, otherwise can affect erasing quality, causes on blank clean not, impact display.
Utility model content:
In order to solve the problem, it is simple that the utility model provides a kind of structure, can be adsorbed in whiteboard surface voluntarily, technical scheme easy to use:
The special blackboard eraser of a kind of blank, main body is cube blackboard eraser, comprise cube shell, enclosure is provided with wiper, also comprise one with the equal-sized blackboard eraser lid of blackboard eraser exterior contour, blackboard eraser lid by brace and blackboard eraser hinged, brace is rectangular plastic tablet, the long limit of brace one is carried out hinged at the horizontal axis place on any one side of blackboard eraser, and another long limit of brace is hinged at the horizontal axis place of the corresponding sides of blackboard eraser lid.
As preferably, upper surface center, the blackboard eraser back side is metallic plate, and upper surface center, the blackboard eraser lid back side is provided with magnetic patch, and described metallic plate is identical with magnetic patch exterior contour, and the magnetic force scope of magnetic patch is in 1500 ~ 3000 Gausses.
As preferably, the corresponding edge of blackboard eraser and blackboard eraser lid is provided with magnetic stripe, and described magnetic stripe width is at 35 ~ 70mm, and the magnetic force scope of magnetic stripe is in 500 ~ 1200 Gausses.
As preferably, the blackboard eraser back side arranges detachable panel, and described detachable panel all the time edge flushes with blackboard eraser edge, by extruding and blackboard eraser compact siro spinning technology.
The beneficial effects of the utility model are:
(1) the utility model also comprises one and the equal-sized blackboard eraser lid of blackboard eraser exterior contour, can cover on wiper surface, avoid the artificial consume on wiper surface when blackboard eraser is no.
(2) in the utility model, upper surface center, the blackboard eraser back side is metallic plate, and upper surface center, the blackboard eraser lid back side is provided with magnetic patch, and at blackboard eraser, the used time can not be adsorbed on whiteboard surface by magnetic patch, and convenient placement, decreases the loss probability of blackboard eraser.
(3) corresponding edge of the utility model blackboard eraser and blackboard eraser lid is provided with magnetic stripe, and at blackboard eraser without in situation, auxiliary blackboard eraser and blackboard eraser cover reality, improve and preserve efficiency.
(4) the blackboard eraser back side arranges detachable panel, is carried out the replacing of the inner wiper of blackboard eraser, thus promotes blackboard eraser service efficiency, extend the service life of blackboard eraser by panel.
Accompanying drawing illustrates:
Fig. 1 is utility model structural representation;
Fig. 2 is eraser structure schematic diagram in utility model;
Fig. 3 is blackboard eraser lid structural representation in utility model.
Detailed description of the invention:
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As Figure 1-3, the special blackboard eraser main body of blank is cube blackboard eraser 1, comprise cube shell 2, shell 2 inside is provided with wiper 3, also comprise one and the equal-sized blackboard eraser lid 4 of blackboard eraser exterior contour, blackboard eraser lid 4 is hinged by brace 5 and blackboard eraser 1, brace 5 is rectangular plastic tablet, the long limit of brace 5 one is carried out hinged at the horizontal axis place on any one side of blackboard eraser 1, another long limit of brace 5 is hinged at the horizontal axis place of the corresponding sides of blackboard eraser lid 4, blackboard eraser lid 4 can be covered on wiper 3 surface when blackboard eraser 1 is no, avoid the artificial consume on wiper 3 surface.
Upper surface center, blackboard eraser 1 back side is metallic plate 6, upper surface center, blackboard eraser lid 4 back side is provided with magnetic patch 7, metallic plate 6 is identical with magnetic patch 7 exterior contour, in the present embodiment, the magnetic force scope of magnetic patch 7 is in 2000 Gausses, at blackboard eraser 1, the used time can not be adsorbed on whiteboard surface by magnetic patch 7, and convenient placement, decreases the loss probability of blackboard eraser 1.
Blackboard eraser 1 is provided with magnetic stripe 8 with the corresponding edge of blackboard eraser lid 4, and magnetic stripe 8 width is at 45mm, and the magnetic force scope of magnetic stripe 8 is in 1000 Gausses, and at blackboard eraser 1 without in situation, auxiliary blackboard eraser 1 closes reality with blackboard eraser lid 4, improves and preserves efficiency.
Blackboard eraser 1 back side arranges detachable panel 9, detachable panel 9 all the time edge flushes with blackboard eraser 1 edge, by extruding and blackboard eraser 1 compact siro spinning technology, is carried out the replacing of the inner wiper 3 of blackboard eraser 1 by detachable panel 9, thus promote blackboard eraser 1 service efficiency, extend the service life of blackboard eraser 1.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
