Abstract
The utility model relates to a two -sided upset blackboard, including being fixed in the blackboard framework on the wall, double -sided blackboard's upper and lower both sides mid point punishment do not through telescopic bracket connect in blackboard framework is last, double -sided blackboard's upper and lower both sides mid point punishment is do not inlayed and is equipped with the axis of rotation, rotation axis connection telescopic bracket is last, about the blackboard framework both sides be equipped with respectively department of resist support hold in double -sided blackboard's upper and lower both sides. Double -sided blackboard pass through telescopic bracket connect in blackboard framework is last, for double -sided blackboard provides the upset space, passes through simultaneously during the telescopic bracket extension the axis of rotation that double -sided blackboard connects is overturn, realizes two -sided purpose of writing. So, reach simple structure, convenient to use avoids inhaleing the dust, improves healthyly and study record effect.
Description
Technical field
The utility model relates to realia technical field, particularly a kind of double-side-turning blackboard.
Background technology
A present class substantially, teacher needs to write very knowledge point and carries out teaching use, but not enough content of writing a class of blackboard, just need teacher ceaselessly to wipe before write, just can carry out next time and again write new content, so, a large amount of dust is had by academics and students's suction body in classroom, health is damaged, in addition, take time to erase the board at normal time in classroom and also cause waste of time, meanwhile, wipe the teaching write and be also unfavorable for that student records classroom notes timely.
Therefore, be necessary to provide a kind of new double-side-turning blackboard, to solve above-mentioned Problems existing.
Utility model content
The purpose of this utility model is to provide a kind of double-side-turning blackboard, and to overcome above-mentioned technical problem, structure is simple, easy to use, avoids sucking dust, improves healthy and study record effect.
The technical scheme realizing above-mentioned purpose is: a kind of double-side-turning blackboard, comprise the blackboard framework be fixed on wall, the midpoint of both sides up and down of Dual-side blackboard is connected on described blackboard framework respectively by telescope support, the midpoint of both sides up and down of described Dual-side blackboard is embedded with turning cylinder respectively, described turning cylinder connects on described telescope support, and the upper and lower both sides of described blackboard framework are respectively equipped with the both sides up and down that blocking part is held in described Dual-side blackboard.
In technique scheme, described telescope support is rhombus telescope support.
In technique scheme, bottom described Dual-side blackboard, two jiaos of places are respectively equipped with groove.
In technique scheme, described blackboard framework is connected with 4 pieces of Dual-side blackboards.
The utility model double-side-turning blackboard, wherein, Dual-side blackboard is connected on described blackboard framework by telescope support, for Dual-side blackboard provides upset space when telescope support extends, the turning cylinder simultaneously connected by described Dual-side blackboard is overturn, and realizes two-sided object of writing.So, reach structure simple, easy to use, avoid sucking dust, improve healthy and study record effect.
Accompanying drawing explanation
Fig. 1 is the utility model double-side-turning blackboard structure schematic diagram;
Fig. 2 is part-structure schematic diagram in Fig. 1.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, those skilled in the art better understand the technical solution of the utility model, below in conjunction with detailed description of the invention also with reference to accompanying drawing, further describe the utility model.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As depicted in figs. 1 and 2, described double-side-turning blackboard comprises the blackboard framework 1 be fixed on wall, is located at 4 pieces of Dual-side blackboards 2 on described blackboard framework 1.
Wherein, the midpoint of both sides up and down of described Dual-side blackboard 2 is connected on described blackboard framework 1 respectively by telescope support 3, and in the present embodiment, described telescope support 3 is rhombus telescope support.For described Dual-side blackboard 2 provides upset space when described telescope support 3 extends.
The midpoint of both sides up and down of described Dual-side blackboard 2 is embedded with turning cylinder 4 respectively, described turning cylinder 4 connects on described telescope support 3, when stretching out described telescope support 3, after providing the space of Dual-side blackboard 2 upset, described Dual-side blackboard is overturn by turning cylinder 4, realize two-sided object of writing, described blackboard framework about 1 both sides are respectively equipped with the both sides up and down that blocking part 10 is held in described Dual-side blackboard 2, facilitate stable being retained in described blackboard framework 1 of described Dual-side blackboard 2.Further, bottom described Dual-side blackboard 2, two jiaos of places are respectively equipped with groove 20, and described groove is used for the clasp of hand, to facilitate the operation overturn described Dual-side blackboard 2.
The utility model double-side-turning blackboard, described Dual-side blackboard 2 is connected on described blackboard framework 1 by described telescope support 3, for Dual-side blackboard 2 provides upset space when telescope support 3 extends, the turning cylinder 4 simultaneously connected by described Dual-side blackboard 2 is overturn, and realizes two-sided object of writing.So, reach structure simple, easy to use, avoid sucking dust, improve healthy and study record effect.
Should be understood that, above-mentioned detailed description of the invention of the present utility model only for exemplary illustration or explain principle of the present utility model, and is not formed restriction of the present utility model.Therefore, any amendment made when not departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.In addition, the utility model claims be intended to contain fall into claims scope and border or this scope and border equivalents in whole modifications.
