Abstract
A folded blackboard comprises a main frame. The left side and the right side of the main frame are respectively connected with a sub frame in a hinged mode. Writing panels are arranged in the main frame and the sub frames in an embedded mode, and the size of each sub frame is one half of the size of the main frame. Components such as the main frame, the sub frames, the writing panels and hinges are reasonably arranged in a matching mode, so that the using cost of the blackboard can be effectively lowered, storing of the folded blackboard by being gathered and folded can be achieved after the blackboard is used, occupied space is small, and transportation and storage is convenient. In addition, the folded blackboard can be folded to be in a certain angle, and can be placed and used at any places conveniently. The condition of visual fatigue when the folded blackboard is used can not happen. The folded blackboard is reasonable and simple in structure, low in cost, good in using effect and worthy to being popularized.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of Folding blackboard.
Background technology
Blackboard is a kind of planar products that can repeated writing, and its plate face is hard, and is multiplex in teaching.At present, blackboard on the market is normally fixing on the wall or hang fixingly by lanyard, is not easy to use at the spaciousness place, also is not easy to change when needed visual position and carrying; In addition, the most monolithic rectangle blackboards that adopt of existing blackboard can't stored collapsed, and it is large to take up an area the space; In addition, when watching for the people who is in the place ahead, blackboard both sides, can't see the content on the blackboard clearly with cleaning, the visual fatigue that easily causes of a specified duration, or even visual impairment, result of use is poor; In addition, the blackboard that minority is arranged is simply several platelets to be connected together by hinge, after the junction is damaged, can't carry out maintain and replace, can only scrap, and has increased use cost.
Summary of the invention
The utility model will solve the problem that above-mentioned prior art exists, and provides a kind of long service life, result of use is good and easily make the Folding blackboard of making good use of maintenance, satisfies people's demand.
The utility model solves the technical scheme that its technical problem adopts: this Folding blackboard, comprise main frame, the main frame left and right sides is hinged with respectively sub-frame, all is inlaid with writing panel in main frame, the sub-frame, and the size of each sub-frame is half of main frame.Like this, when needs are carried, the folding gathering in of sub-frame got final product, the integral body area that takes up space can directly dwindle one times, and is convenient and swift; In use, the revolute pair framework makes between sub-frame and the main frame and forms certain angle as required, also can clearly see the content on the blackboard over against blackboard when watching for the people who is in the place ahead, blackboard both sides, can not cause visual fatigue; And after sub-frame draws in and is converted into certain angle, just whole setting of blackboard can have been put, be convenient to use in any place, result of use is good; And each writing panel does not connect directly and connects, but connects by main frame, sub-frame, in use for some time, if there is damage the junction, can directly change main frame or sub-frame gets final product, and need not to scrap whole blackboard, greatly reduces use cost.
Setting is connected through the hinge between main frame and the sub-frame.Like this, chain connection is reliable and stable.
Main frame, sub-frame are wooden rectangular frame.Wood frame is lightly durable, is particularly suitable for children and uses.
Writing panel is magnet board.Like this, can carry out aided education by the sticking note toy of some magnetic force or stationery, lively novel, easily promote the children for learning excitement.
The effect that the utility model is useful is: of the present utility model rational in infrastructure, simple, reasonable coordination setting by assemblies such as main frame, sub-frame, writing panel and hinges, can effectively reduce the use cost of blackboard, and after use, can draw stored collapsed in, the area that takes up space is little, is convenient to transportation, deposits, in addition, also can be folded into certain angle, be convenient to put use in any place, and occur in the situation that visual fatigue can not occur in use.The utility model cost is low, and result of use is good, is worthy to be popularized.

Description of reference numerals: main frame 1, sub-frame 2, writing panel 3, hinge 4.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing: this Folding blackboard in the present embodiment, comprise main frame 1, main frame 1 left and right sides is hinged with respectively sub-frame 2, main frame 1, the sub-frame 2 interior writing panels 3 that all are inlaid with, the size of each sub-frame 2 is half of main frame 1.
Be connected setting by hinge 4 between main frame 1 and the sub-frame 2.
Writing panel 3 is magnet board.
When the utility model uses, only need sub-frame 2 is launched, make it with main frame 1 at an angle (such as 120 °, 145 °, 150 ° or 170 ° etc.) be positioned over pallet, ground or desktop etc. and locate to use and get final product, convenient to operation.Make make good use of after, can draw in sub-frame 2 is folding, be convenient to carrying, deposit.In addition, after using a very long time, if there is damage the junction, can directly change main frame 1 or sub-frame 2 gets final product, need not to scrap whole blackboard, greatly reduce use cost.
Although the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
