Description
Technical field
The utility model relates to teaching aid field, particularly a kind of geographical teaching lift chart hanger.
Background technology
at present in geographical teaching, the teaching material figure mostly is electronic edition under multimedia teaching environment or the paper printing version under conventional environment, due to funds and other reasons, a lot of schools do not possess the condition of whole use electronic editions, therefore the paper printing version also will be widely used in some schools in a long time, wall chart adopts the modes such as adhesive tape or magnetic block pressure more at present, but because this kind wall chart mode does not have elevating function, and the figure of geographical teaching mostly is the larger wall chart of the space of a whole page, therefore when hanging medium-and-large-sized teaching material figure in large-scale classroom, just needing the student to step down on desk or ladder hangs, one is wasted time and energy, there is potential safety hazard in its two ascend operation.
The utility model content
For the problem of prior art, the utility model provides a kind of simple in structure, reasonable in design, easy to operate, safe and reliable teaching Map-hanging set.
Its technical scheme is: comprise guiding fixed pulley group, suspension fixed pulley group, the fixing guy winding device of suspension fixed pulley and bottom fixed side by side on top; Described guiding fixed pulley group comprises two left and right fixed pulleys side by side, and described suspension fixed pulley group comprises two side by side fixed pulleys up and down; Described bracing wire one end is fixed on wind, the other end is divided into two-way by draw ring, wherein one the tunnel is connected with an end of the first clamping plate by superposed fixed pulley and suspension fixed pulley in one of them fixed pulley on the leading block group, suspension assembly pulley successively, another road is connected with the other end of the first clamping plate by the fixed pulley that is positioned at the bottom in another fixed pulley on the leading block group, suspension assembly pulley successively, the two ends of the first clamping plate bottom connect the second clamping plate by bracing wire respectively, and described the first clamping plate and the second clamping plate are the length adjustable structure; Described wind comprise outside box body with and the inner cylinder that is used for being wound around bracing wire that is provided with, the motor that is used for the head roll rotation, the lateral surface of box body is provided with the action button of controlling motor.
Described the first clamping plate be connected clamping plate and all be connected with bracing wire by the connecting ring on it, be convenient to dismounting.
The utility model is simple in structure, reasonable in design, easy to operate, and the utility model is convenient hangs medium-and-large-sized geography teaching material drawing in large-scale classroom, time saving and energy saving and safe and reliable.
