Abstract
The utility model discloses a detachable scale type compasses belongs to the drawing utensil, circular curve plotter or the similar technical field of instrument unit. It mainly comprises handle, scale rod, pen clip, set screw, compasses landing leg. The compasses landing leg is the base of whole compasses, realizes being connected and can insert the compasses landing leg and fix once more with scale rod through the twist grip. The dismantlement problem of handle has been solved in the design of compasses landing leg and handle structure. Through the translation of pen clip, realize radial regulation. This practicality new tool simple structure, the flexible operation, the convenient dismantlement is carried. Be applicable to student, teacher's drawing, have practical value and economic value.
Description
Technical field:
The utility model relates to novel bow compass, belongs to drawing appliance, circular curve plotter or analogous instrument technical group field.
Background technology:
At present, tradition two foot type compasses, adopt upper end handle, middle part rotating shaft, the structure that lower end can separate or close up in limited angle, by bipod end measure length with adjustment paint and justify or the radius size of circular arc, this structure efficiently solves the drafting of circle or circular arc, but still have some deficits: compasses supporting leg draw time can not be vertical with paper, easily slide during picture, cause drawing shape inaccuracy; During picture, compasses supporting leg need insert in drawing board through paper, makes compasses supporting leg and nib actual span on paper be less than measured length, cause drawing shape inaccuracy.
The utility model patent, when solving traditional drawing for compasses by novel structural design, compasses supporting leg easily slides, actual span coarse technical problem during drawing.
Summary of the invention:
The purpose of this utility model is to provide a kind of novel bow compass, and during to solve traditional drawing for compasses, compasses supporting leg easily slides, actual span coarse technical problem during drawing.
The new technical scheme that above-mentioned technical problem to be solved in the utility model adopts be achieved in that the novel bow compass of this utility model primarily of: handle, scale bar, pen clip, compasses supporting leg form.Its handle is cylindrical step shape shaft, take aluminium alloy as material, through machining manufacture.Its scale bar is ruler one end band annulus sleeve-shaped, take aluminium alloy as material, through machining manufacture.Its pen clip is band sliding tray rectangular shape, take aluminium alloy as material, through machining manufacture.Its compasses supporting leg is one end tapered end thereof cylindrical shape, take aluminium alloy as material, through machining manufacture.
In shape, structure and combination thereof: the Intercalation part of handle is the base of whole compasses, this part matches with compasses supporting leg, and the Intercalation part of compasses supporting leg and handle can freely be dismantled.The rib of handle Intercalation part coordinates with the opening on scale bar annulus sleeve, makes can not relatively rotate between scale bar and handle.The sliding tray of pen clip matches with scale bar, and pen clip can along the left and right translation of scale bar.Hold-down screw is screwed in the retaining thread hole of pen clip, tightens the position that pen clip fixed by screw.Pen clip can clamp drawing pen (comprising water-color paintbrush, pencil etc.).In drawing, the compasses supporting leg of this novel bow compass is all vertical with paper with nib, when solving picture compasses supporting leg easily slide, actual span coarse technical problem when drawing.
Compared with traditional compasses, novel bow compass of the present utility model has three advantages and improvement:
The first, the compasses supporting leg of novel bow compass of the present utility model simultaneously perpendicular to paper with nib, not easily skids during drawing, draws more stable.
The second, the pen clip of novel bow compass of the present utility model can along the left and right translation of scale bar, and the scale on scale bar accurately can indicate current written position, can facilitate determine accurately draw circle or the radius of circular arc.
3rd, novel bow compass of the present utility model is detachable, is convenient for carrying.
Accompanying drawing explanation
Fig. 1: be novel bow compass of the present utility model face structural representation;
Fig. 2: the structural representation being the compasses supporting leg of novel bow compass of the present utility model;
Fig. 3: the structural representation being the scale bar of novel bow compass of the present utility model;
Fig. 4: the structural representation being the handle of novel bow compass of the present utility model;
The label declaration of parts in schematic diagram:
1 scale bar 2 pen clip 3 drawing pen 4 hold-down screw 5 handle 6 compasses supporting leg
Detailed description of the invention
For making object of the present invention, technical scheme is clearer and more definite, and below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, its structure is mainly as follows:
1. scale bar 2. pen clip 3. drawing pen 4. hold-down screw 5. handle 6. compasses supporting leg
Below by using method, illustrate further the dynamic structure relation of dismountable scale type compasses: first the wedging with rib (5) can be fixed scale bar rotational structure in use and insert with scale bar (1) and be connected, and then inserted by handle (5) can compasses supporting leg (6).Pen clip (2) is inserted in scale bar, can realize the adjustment of radius of circle, and can pass through hold-down screw fixed position, occurs sliding when preventing from drawing.This device is realizing while radius accurately draws, again detachably, facilitating and carrying and storage.Its compasses supporting leg and nib, simultaneously perpendicular to paper, make compasses not easily skid more stable.This addresses the problem traditional compasses less stable, sliding usually appears in the needle point playing fixation in drawing course.Accuracy is poor, and compasses bipod is difficult to obtain radius of a circle accurately, draws and has the circle of radius requirement also to need the help of rule.
The preferred plan realizing the utility model patent is material with aluminium alloy, utilizes the basic equipment of machining, take small lot to produce by batch, promote the use of novel bow compass.Realize practical value and the economic worth of novel bow compass.
Claims (3)
1. dismountable scale type compasses, it is by scale bar (1), pen clip (2), hold-down screw (4), handle (5) compasses supporting leg (6) form, it is characterized in that: the rib of handle (5) Intercalation part coordinates with the opening on scale bar (1) annulus sleeve, make can not relatively rotate between scale bar and handle, compasses supporting leg (6) can freely be dismantled with the Intercalation part of handle (5).
2. dismountable scale type compasses according to claim 1, is characterized in that the sliding tray of pen clip (2) matches with scale bar (1), and pen clip can along the left and right translation of scale bar.
3. dismountable scale type compasses according to claim 1, it is characterized in that hold-down screw (4) is screwed in the retaining thread hole of pen clip, tighten the position that pen clip fixed by screw, pen clip can clamp drawing pen (3).
