Abstract
The utility model relates to a blackboard, in particular to a push-pull type combined blackboard. The push-pull type combined blackboard comprises at least two small blackboards and a blackboard framework, and is characterized in that every two small blackboards form the integrated combined blackboard; the small blackboards are in push-pull connection with one another in a stacked manner; grooves are formed on the upper rims and the lower rims of the small blackboards; the blackboard framework is provided with sliding rails of which the number is the same as that of the small blackboards and which are matched with the small blackboards; the small blackboards are respectively clamped on the sliding rails; a dust collection trough is formed on the lower side of the blackboard framework; the small blackboards are made of black hard plastic or hard plastic in other colors; hidden handles are arranged on one side of the left border and one side of the right border of each small blackboard; a hairbrush or a vertical long-strip blackboard eraser made of sponge is fixed on the inner side of the back of the right border or the left border of each small blackboard; and dust leakage holes are uniformly formed in the sliding rails of the blackboard framework. Therefore, the push-pull type combined blackboard has the advantages of fully using a blackboard space and improving the teaching efficiency along with simple structure, multiple functions and convenience in use, and students can see contents on the blackboard clearly; and furthermore, the writing area of the blackboard is expanded, and the blackboard panel is easy to clean.
Description
(1) technical field
The utility model relates to a kind of blackboard, particularly a kind of plug-type combined blackboard.
(2) background technology
Traditional blackboard is fixed, and the student of both sides, classroom does not see the content of blackboard than the distally usually, has increased the probability of student's stravismus, has influenced student's eyesight.Existing in addition blackboard is single plate face, and area is limited, write and write after must wiping after full again, but some content also need keep, and this has just caused the inconvenience of teaching.Normal blackboard needs manual work little by little to wipe writing, not only requires great effort but also waste time, and like the need projection, the projection screen of a rollable will be installed above blackboard more also, has increased instruction cost; Also have some Push-pull blackboards at present, the complex structure that has, inconvenience is installed, operation, and its small blackboard that has has stationarity, and is not very convenient.
(3) summary of the invention
The utility model provides a kind of plug-type combined blackboard simple in structure, easy to use in order to remedy the shortcoming of existing blackboard.
The utility model is realized through following technical scheme:
A kind of plug-type combined blackboard comprises small blackboard and blackboard framework, it is characterized in that: said small blackboard has two at least; Form a monoblock combined blackboard for per two; Small blackboard is the superposing type push-and-pull and connects, and lower limb all is provided with groove on it, and blackboard framework is provided with and small blackboard equal number and identical slideway; Small blackboard is installed on respectively on the slideway, and the blackboard framework downside is provided with dust collecting trough.
The plug-type combined blackboard of the utility model, said small blackboard is processed by black or other color rigid plastics, and its left and right side frame one side all is provided with dark handle, and left frame or inboard, the left frame back side are fixed with the perpendicular shape strip blackboard eraser of hairbrush or sponge material.
The plug-type combined blackboard of the utility model is evenly distributed with powder leakage hole on the slideway of blackboard framework.
Therefore, the beneficial effect of the utility model is: this plug-type combined blackboard, and simple in structure, diverse in function, easy to use, can make full use of the blackboard space, enlarge the blackboard write area, make things convenient for the student to see the blackboard content clearly, the cleaner plate face improves efficiency of teaching easily.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of the utility model.Accompanying drawing 2 is the utility model blackboard framework slideway sketch map.Among the figure, 1 small blackboard, 2 grooves, 3 dark handles, 4 blackboard erasers, 5 slideways, 6 dust collecting troughs, 7 blackboard frameworks, 8 powder leakage holes.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises small blackboard 1 and blackboard framework 7; It is characterized in that: said small blackboard 1 has two at least, forms a monoblock combined blackboard for per two, and small blackboard 1 is the superposing type push-and-pull and connects; Lower limb all is provided with groove 2 on it; Blackboard framework 7 is provided with and small blackboard 1 equal number and identical slideway 5, and small blackboard 1 is installed on respectively on the slideway 5, and blackboard framework 7 downsides are provided with dust collecting trough 6; Said small blackboard 1 is processed by black or other color rigid plastics, and its left and right side frame one side all is provided with dark handle 3, and left frame or inboard, the left frame back side are fixed with the perpendicular shape strip blackboard eraser 4 of hairbrush or sponge material; Be evenly distributed with powder leakage hole 8 on the slideway 5 of said blackboard framework 7.
Adopt the plug-type combined blackboard of the utility model, small blackboard 1 can support blank pen and chalk write according to the difference of color, owing to small blackboard 1 can free move left and right; During cleaning, only need push-and-pull front side, left and right sides small blackboard 1, then blackboard eraser just with the writing of rear side small blackboard 1 disposable wipe clean; If need keeping also, content can reach through overlapping other small blackboards 1; According to the material of pen, blackboard eraser 4 cleanings of available unlike material, blackboard eraser 4 can be changed at any time; Owing to be evenly distributed with powder leakage hole 8 on the slideway 5, then dust then can be received through powder leakage hole 8 and fall in the dust collecting trough 6, makes dust can not stop up slideway 5; In addition small blackboard 1 can also all move on to a side, abdicates the projection of imparting knowledge to students of other space, and the small blackboard 1 of different colours can also be used to doing the pinup picture teaching.Therefore, the beneficial effect of the utility model is: this plug-type combined blackboard, and simple in structure, diverse in function, easy to use, can make full use of the blackboard space, enlarge the blackboard write area, make things convenient for the student to see the blackboard content clearly, the cleaner plate face improves efficiency of teaching easily.
