Technical field
The utility model relates to a kind of improvement of teaching gauge structure.
Background technology
In our modern society, set square is one of the main drawing tool of immunologing mathematics, measuring angle.Every secondary set square is made up of two special right angled triangles.One is isosceles right angle triangles, and another is the right angle triangle (hereinafter referred to as elongated set square) of special angle.Use set square can draw the angle of the integral multiple of 15 ° easily.Particularly one piece of set square and T-square are coordinated, according to order from bottom to top, a series of vertical line can be drawn. T-square is coordinated the angle that can draw 30 °, 45 °, 60 ° with a set square.Usually according to principle Oblique line drawing from left to right during picture.Coordinate the oblique line that can also draw 15 °, 75 ° with T-square with two pieces of set squares.Coordinate with two pieces of set squares, the parallel lines of any figure line can be drawn.Two pieces of set squares are pieced together and can be drawn 135 °, 120 °, 150 °, 75 °, the angle of 105 °.
But existing set square also exists some problems, be difficult to when such as using on blackboard fix, and need when drawing long straight line on blackboard to have docked several times, use inconvenience.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of and conveniently fixes and extensible a kind of teaching set square.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises set square body, it is characterized in that: in set square body one side, be provided with sliding cavity, be provided with storage chamber above sliding cavity, in set square body, set square side is provided with the opening corresponding with sliding cavity; Extension block is movably set with in sliding cavity, block is movably set with in storage chamber, described block size is corresponding to sliding cavity size, the transverse slipway of horizontal direction is provided with in described sliding cavity, extension rod is provided with the pulley corresponding to described slideway, in storage chamber and sliding cavity, be provided with the end slipway of vertical communication storage chamber and sliding cavity, block be provided with end slipway to corresponding pulley; The upper surface of set square body to be provided with storage chamber with sliding cavity to the longitudinal opening be communicated with, the stop-surface exposed at opening part is connected with action bars; The lower surface of set square body is provided with several magnet.
As a kind of preferred version, described end slipway is arranged on the inner chamber bottom surface of sliding cavity and storage chamber.
As another kind of preferred version, described end slipway is arranged on the inner chamber side of sliding cavity and storage chamber.
As another preferred version, described magnet quantity is three, and wherein two magnet is embedded in two angles place of set square body lower surface respectively, and the 3rd magnet is embedded on the lower surface of extension rod.
Further, handle can be set on set square body upper surface.
The beneficial effects of the utility model:
1, convenient fixing
The utility model is provided with magnet on set square body lower surface.The blackboard that present school instruction uses generally is magnet board, uses magnet that set square lower surface is arranged can by set square ontological adsorption theory on blackboard, easy to use.
2, can extend
Sliding cavity is provided with in the utility model set square body one side, extension rod is provided with in sliding cavity, described extension rod is connected with pulley by chute with between sliding cavity, extension rod can slide in sliding cavity, and slide into outside sliding cavity by opening, extend the length of set square body side.Because sliding cavity sidewall has certain thickness, some errors may be there will be when drawing straight line, but rule of thumb, on middle and primary schools' blackboard, picture is said generally does not need completely accurately class hour, and the extended set square base side edge lengths that the utility model brings facilitate effect, the efficiency of drawing during teaching can be made greatly to improve.
