Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of teaching apparatus for mathematics, comprise base 1 and cabinet, base 1 top is provided with telescopic support bar, base 1 below is provided with roller 4, described cabinet is located at support bar top, described cabinet comprises casing 3 and chamber door 10, between casing 3 and chamber door 10, be provided with lockset 11, in casing 3, be provided with multiple difform article putting grooves, article putting groove comprises straight flute 5, graphometer groove 6, set square groove 8 and compasses groove 7, straight flute 5, graphometer groove 6, set square groove 8, compasses groove 7 middle parts are equipped with elastic reducing-fixing band 9, chamber door 10 is provided with movable writing plate and blackboard eraser, blackboard eraser is fixed on movable writing plate by flat thin magnet, movable writing plate can be used for drawing before classroom, save time in classroom.
Support bar comprises support arm 2, is T-shaped inner support 12, inner support 12 inserts in support arm 2 through the upside of support arm 2, and can vertically move up and down, and support arm 2 both sides are respectively equipped with spring 13, spring 13 one end are connected with inner support 12, and the other end is connected with height drive plate 14.
In casing 3, be provided with height adjustment control, height adjustment control is connected with height drive plate 14 by motor, and chamber door 10 is provided with height by-pass cock, and height by-pass cock is connected with height adjustment control.
When use, by height by-pass cock, teaching apparatus for mathematics is transferred to suitable height and position, then opens chamber door 10, in article putting groove, take out mapping, the demonstration equipment of wanting use, and can utilize movable writing plate to carry out drawing before classroom, save time in classroom.Be finished after drawing tools, first put back in corresponding article putting groove, then, by height by-pass cock, support bar is reduced, reduce the occupation of land volume of teaching apparatus for mathematics, then teaching apparatus for mathematics is placed on to a position that does not affect teaching, study and deposits.The utility model is simple in structure, easy to operate, is applicable to doing on a large scale promoting the use of.
