Description
Technical field
The utility model relates to a kind of blackboard, relates in particular to a kind of double freedom blackboard.
Background technology
Blackboard is teaching instrument commonly used, has a variety of blackboards on the market.The blackboard that middle and primary schools use, normally fixed blackboard.The blackboard that university uses, normally blackboard that up and down can push-and-pull.Along with multimedia equipments such as computer, projecting apparatus are used for the classroom, make education activities become more effective and convenient.Yet projecting apparatus can be incident upon on the blackboard usually, so the part of blackboard just can not obtain utilizing, the utilization rate of blackboard descends.The up and down push-and-pull of existing blackboard can not left and right sides push-and-pull, still has a lot of drawbacks in the use.A lot of blackboards all are manually to realize push-and-pull, waste time and energy.
The utility model content
The purpose of this utility model provides a kind of double freedom blackboard, and push-and-pull blackboard up and down can also Bidirectional horizontal slide blackboard, makes the utilization rate of blackboard be improved, and people also can utilize electric energy to realize the movement of blackboard.
To achieve these goals, the technical solution of the utility model is: a kind of double freedom blackboard, comprise outside framework, be provided with draw-in groove in the described outside framework left and right sides, inner frame I and inner frame II are arranged in the draw-in groove, and inner frame I and inner frame II flexibly connect, be provided with groove in the described inner frame I upper and lower sides, blackboard I and blackboard II are located in the groove, are provided with groove in the described inner frame II upper and lower sides, and blackboard III and blackboard IV are located in the groove.
Described blackboard I is positioned at blackboard II the place ahead, and blackboard I rear sidepiece is equipped with the pulley I, and chain links together blackboard I and blackboard II by the pulley I, and described pulley I axis is connected in the motor I.
Described blackboard III is positioned at blackboard IV the place ahead, and blackboard III rear sidepiece is equipped with the pulley II, and chain links together blackboard III and blackboard IV by the pulley II, and described pulley II axis is connected in the motor II.
Described inner frame I is positioned at inner frame II the place ahead, and top, inner frame I right side is equipped with the pulley III, and chain links together inner frame I and inner frame II by the pulley III, and described pulley III axis is connected in the motor III.
People can push-and-pull blackboard I and blackboard II, makes blackboard I and blackboard II location swap, and push-and-pull blackboard III and blackboard IV can be exchanged the position of blackboard III and blackboard IV.When push-and-pull inner frame I and inner frame II, can exchange the position of inner frame I and inner frame II, can reserve many spaces between inner frame I and the inner frame II, projecting apparatus can be incident upon white space, can not influence the use of blackboard, improve the utilization rate of blackboard, can effectively electronic equipment and blackboard be combined, improve teaching level.
Between blackboard I and blackboard II, blackboard III and blackboard IV and inner frame I and the inner frame II pulley is installed, the pulley axis is connected in motor, and people can realize the mutual replacing of blackboard position by electric energy, and are quick and convenient, saves time and laborsaving.

The specific embodiment
As shown in Figure 1, a kind of double freedom blackboard, comprise outside framework 1, be provided with draw-in groove in described outside framework 1 left and right sides, inner frame I 2 and inner frame II 3 are arranged in the draw-in groove, and inner frame I 2 and inner frame II 3 flexibly connect, be provided with groove in described inner frame I 2 upper and lower sides, blackboard I 4 and blackboard II 5 are located in the groove, are provided with groove in described inner frame II 3 upper and lower sides, and blackboard III 6 and blackboard IV 7 are located in the groove.People's push-and-pull blackboard I 4 and blackboard II 5 make blackboard I 4 and blackboard II 5 location swaps, and people's push-and-pull blackboard III 6 and blackboard IV 7 can be exchanged the position of blackboard III 6 and blackboard IV 7.When push-and-pull inner frame I 2 and inner frame II 3, can exchange the position of inner frame I 2 and inner frame II 3, can reserve many spaces between inner frame I 2 and the inner frame II 3, projecting apparatus can be incident upon white space, can not influence the use of blackboard, improve the utilization rate of blackboard, can effectively electronic equipment and blackboard be combined, improve teaching level.
As shown in Figure 3, described blackboard I 4 is positioned at blackboard II 5 the place aheads, and blackboard I 4 rear sidepieces are equipped with pulley I 8, and chain links together blackboard I 4 and blackboard II 5 by pulley I 8, and described pulley I 8 axis are connected in motor I 9.People open motor I 9 by electric energy, drive the rotation of pulley I 8, realize the exchange of blackboard I 4 and blackboard II 5 positions, improve the utilization rate of blackboard, and are also time saving and energy saving.
As shown in Figure 4, described blackboard III 6 is positioned at blackboard IV 7 the place aheads, and blackboard III 6 rear sidepieces are equipped with pulley II 10, and chain links together blackboard III 6 and blackboard IV 7 by pulley II 10, and described pulley II 10 axis are connected in motor II 11.People open motor II 11 by electric energy, drive the rotation of pulley II 10, realize the exchange of blackboard III 6 and blackboard IV 7 positions, improve the utilization rate of blackboard, and are also time saving and energy saving.
