Abstract
A teaching magnetic abacus belongs to the technical field of teaching aid equipment. To facilitate the teaching of abacus, a fur abacus is usually hanged on the blackboard; however, the fur on rods is easy to fall of due to repeated poking of abacus counters, thus causing the falling of the abacus counters and influencing the teaching. The teaching magnetic abacus has the technical proposal that: a frame (1) is provided with a magnetic square shaft lever (2), and the magnetic square shaft lever (2) is strung with squared hole iron abacus counters (3). The teaching magnetic abacus has the advantages of reasonable structural design, and ingenious and novel conception. Hanging the frame on the blackboard vertically, the teacher can poke the squared hole iron abacus counters up and down along the magnetic square shaft lever. As the magnetic square shaft lever is magnetic and the squared hole iron abacus counters are made of iron materials, the two parts can mutually attract to keep the poked squared hole iron abacus counters stay still at any position of the magnetic square shaft lever. The teaching magnetic abacus facilitates abacus teaching and saves time and labor, which is an updated product of the existing fur abacus.
Description
Technical field
The utility model relates to teaching aid device technique field, is a kind of teaching magnetic abacus more specifically.
Background technology
On to the student, to hang a mao abacus during abacus on the blackboard and be convenient to teaching, this hair abacus has influenced teaching because abacus bead often dials to dial come off the easily abacus bead of losing control of one's feelings of the hair that goes to make on the bar, and the hair of teacher when dialling abacus bead because on the bar makes dermal sensation on hand uncomfortable more firmly.
Summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of teaching of design magnetic abacus.Its technical scheme is: magnetic square shaft bar is installed on the framework, is installed with square hole irony abacus bead 3 on magnetic square shaft bar 2.The advantage of this utility model is: this teaching magnetic abacus reasonable in design, novelty is skillfully constructed, vertically hang on the blackboard framework, when giving birth to rechoning by the abacus, teachers ' teaching stirs square hole irony abacus bead up and down along magnetic square shaft bar with finger, because magnetic square shaft bar is magnetic and square hole irony abacus bead is that ferrous material is made and can be attracted each other that to make the square hole irony abacus bead of stirring be in any stationkeeping of magnetic square shaft bar motionless, use its religion abacus convenient and time-saving laborsaving, this teaching is the renewal product of existing hair abacus with the magnetic abacus.
Description of drawings
This accompanying drawing is the utility model structural representation.In the accompanying drawing: 1, framework, 2, magnetic square shaft bar, 3, square hole irony abacus bead.
Embodiment
Magnetic square shaft bar 2 is installed on the framework 1, on magnetic square shaft bar 2, is installed with square hole irony abacus bead 3.Vertically hang on the blackboard framework 1, when giving birth to rechoning by the abacus, teachers ' teaching stirs square hole irony abacus bead 3 up and down along magnetic square shaft bar 2 with finger, because magnetic square shaft bar 2 is magnetic and square hole irony abacus bead 3 is made for ferrous material and can be attracted each other that to make the square hole irony abacus bead of stirring 3 be in any stationkeeping of magnetic square shaft bar 2 motionless, uses its to teach abacus convenient and time-saving laborsaving.
