Abstract
The utility model belongs to teaching training aid, which relates to a multifunctional cyclograph and comprises a sliding rod. The sliding rod is formed by two-stage or more than two-stage tubular rod bodies which are sleeved. The innermost rod body of the sliding rod is provided with a rotary shaft vertical to the rod body and the rotary shaft is connected with an absorption piece. The outermost rod body of the sliding rod is provided with a clamp which is, together with the absorption piece, located at the same side of the sliding rod. The clamp is provided with a locking bolt. The utility model can be used to draw circles with any sizes on a blackboard or a whiteboard and at the same time, the size is controlled precisely without damaging the board surface.
Description
Technical field
The utility model belongs to teaching aid, relates to the picture round belting, particularly a kind of multi-functional cyclograph.
Background technology
In teaching process, the circle that often need on blackboard or blank, draw is many at present with big compasses realization; Because a pin of compasses is sharp-pointed pin or nail, can cause the damage of blackboard or blank when in use, simultaneously; Another pin of big compasses is designed to the chalk anchor clamps, is merely able to clamp chalk, on blank, just can't use; In addition, compasses are drawn the restriction that round size receives compasses bipod length, the circle of the precise radius of can not drawing.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the purpose of the utility model is to provide a kind of multi-functional cyclograph, the circle of size arbitrarily that can on blackboard or blank, draw, and size is accurately controlled, and does not hinder the plate face.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of multi-functional cyclograph; Comprise litter 1, litter 1 by two-stage or the tubular rod body more than the two-stage step by step socket form, the innermost layer pole body of litter 1 is provided with the rotating shaft vertical with the pole body 2; Rotating shaft 2 connects adsorption piece 5; The outermost layer pole body of litter 1 is provided with anchor clamps 3, and adsorption piece 5 and anchor clamps 3 are positioned at the same side of litter 1, and clamping screw 4 is arranged on the anchor clamps 3.
Described adsorption piece 5 can perhaps other has the material or the structure of adsorptivity for sucker, magnetic patch.
On each grade pole body of said litter 1 the length scale value is arranged, with accurate control picture radius of circle.
Said litter 1 adopts memorial alloy tubing.
The utility model compared with prior art has the following advantages:
1) do not hinder the plate face, adopt adsorption piece to contact, can not damage the plate face with the plate face;
2) be convenient to adjustment size, adopt the litter of stretching structure, make the convenient adjustment of picture circle size.
3) draw the circle controlled amount, the length scale value on the pole body can accurately be controlled drawn radius of a circle.
Description of drawings
Fig. 1 is the structural representation of the utility model, and litter is a two-stage pole body.
Fig. 2 is the structural representation of the utility model, and litter is three grades of pole bodies.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out more detailed explanation.
Embodiment one
As shown in Figure 1, the utility model is a kind of multi-functional cyclograph, comprises litter 1; Litter 1 by two-stage tubular rod body step by step socket form, its material is a memorial alloy, as required mutually required corresponding length of pull and relative fixed; The innermost layer pole body of litter 1 is provided with the rotating shaft vertical with the pole body 2; Rotating shaft 2 connects adsorption piece 5, and the outermost layer pole body of litter 1 is provided with anchor clamps 3, and adsorption piece 5 and anchor clamps 3 are positioned at the same side of litter 1; Adsorption piece 5 can perhaps other has the material or the structure of adsorptivity for sucker, magnetic patch; Anchor clamps 3 then are common structure that can the clamping shaft, and anchor clamps clamping screw 4 is arranged on it, on the pole body of litter 1 the length scale value are arranged.
During use, according to drawing radius of circle, litter 1 is adjusted to needed length, then chalk is placed anchor clamps 3, the clamping screw that carries with anchor clamps 34 is fixed chalk, adsorption piece 5 is fixed on the blackboard, and be fulcrum with it, rotary picture is justified.
Embodiment two
As shown in Figure 2, compare with embodiment, unique difference is, litter 1 by triode shape pole body step by step socket form.
In like manner, in the utility model, the pole body progression of litter 1 can be provided with socket step by step as required arbitrarily.
The utility model adopts adsorption piece to contact with the plate face, adopts the telescopic litter of band scale simultaneously, neither can damage the plate face, can accurately adjust picture circle size again, and is simple in structure, convenient and practical.
