Description
Technical field
The utility model relates to a kind of teaching aid, specifically a kind of teaching frame chi.
Background technology
In the primary school Chinese classroom, the teacher need draw grid or matts in order to allow the student better finish writing word on blackboard, write in grid or matts, teaches students how to finish writing Chinese character with this.But the teacher is when drawing grid or matts, need on blackboard, to draw straight line earlier by a ruler, and then carry out grid or matts according to this straight line and draw, so not only waste time and energy, and the effect of drawing out is bad, can not guarantee horizontally flat vertically influence attractive in appearancely, is unfavorable for imparting knowledge to students.
Summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of teaching reasonable in design, simple in structure frame chi is provided.
The technical scheme that its technical problem that solves the utility model adopts is: comprise riser and transverse slat, one end of orthogonal riser and transverse slat is connected together, be installed with vertical positioning sleeve on the described riser and be slidingly connected with it, described transverse slat is provided with the located lateral cover and is slidingly connected with it, vertical positioning sleeve is provided with the vertical crossfoot of riser and with the one end and is connected, the located lateral cover is provided with the vertical perpendicular chi of transverse slat and with the one end and is connected, be respectively arranged with slideway on crossfoot and the perpendicular chi, be installed with the locking button in the slideway, the locking button is connected together crossfoot and perpendicular chi.
Vertical positioning sleeve is provided with positioning knob.
The located lateral cover is provided with positioning knob.
Be respectively arranged with scale on riser and the transverse slat.
Vertical positioning sleeve and located lateral cover are made by transparent material respectively.
During use, rotational lock button and positioning knob are regulated the position of crossfoot and perpendicular chi, determine the size that will draw grid by the scale on transverse slat and the riser, determined size after, regulate positioning knob once more and lock button, each several part is located, prevent that it from moving.
A kind of teaching of the present utility model is used the frame chi compared with prior art, and the beneficial effect that is produced is:
Have characteristics such as reasonable in design, simple in structure, easy to use, function admirable, practicality, can allow the teacher very rapidly on blackboard, carry out the drafting of grid or matts, reduced teacher's labour intensity, improved quality of instruction.
