Abstract
The utility model relates to compasses, in particular to a sucker-type multifunctional circle drawing device, mainly comprising a rubber sucker, an extension scale and a pen clamping sleeve, etc. The sucker is used as a center fixed point, and angle measuring calibration is printed on a surface of the sucker, and one end of the extension scale which is connected to the sucker via a screw is provided with a pointer, and the other end is provided with the slidable pen clamping sleeve, and a pen is arranged on the pen clamping sleeve, and the needed circle, hemicycle, ellipse and various angles can be drew at one time. The screw on the sucker is provided with a drawing pin with a cap, which is not only anti-stabbing but also used to support for drawing on a plank when turned over. The utility model utilizes new technology such as vacuum pull and effectively solves disadvantages of traditional compasses, which has the advantages of convenient carrying, spacious appearance, complete function and flexible use, and can be widely used in teaching and engineering drawing.
Description
One, technical field:
The utility model relates to a kind of drawing compasses, the multi-functional cyclograph of particularly a kind of sucked type.
Two, background technology:
Be old-fashioned mostly at present at widely used drawing compasses in the Graphing of Engineering or on the teaching aid, formed by compasses body, compasses leg, compasses pen clip and handle, this traditional compasses are drawn bowlder in reality, iron pin on the compasses leg is incessantly fixing on smooth plate face, usually skid, misplace, use both inaccurate, inconvenient, weak effect, hard again.
Three, summary of the invention:
Use traditional compasses drawing brought on the circle worried or inconvenient in order to solve, the spy has invented the multi-functional cyclograph of a kind of sucked type.This cyclograph is characterised in that, its supporter is the index dial that a kind of surface has 360 degree, and the bottom has the bracing or strutting arrangement of rubber suction cups, bracing or strutting arrangement is connected with screw with a shrinkage-rule that has scale, one end of shrinkage-rule has pointer, and the other end that has a handle is equipped with slidable Casing with pen, in addition, the figure pin is housed above the described screw, and has the pin cap above the figure pin.
The present invention has utilized new technologies such as pull of vacuum, and the iron pin that can solve effectively on traditional compasses leg is incessantly fixing on smooth plate face, the drawback of usually skidding.
The present invention is made up of sucker, shrinkage-rule, Casing with pen etc.Adopt sucker to make the center fixation point, on the connected shrinkage-rule Casing with pen is arranged, be printed on angle measuring calibration above the sucker, can disposablely finish making such as circle, semicircle, angle, be furnished with the figure pin on the screw of sucker center fixation point reverse side, also can on plank, use.The present invention both can draw circle, also can draw angle, have carry light, aesthetic in appearance, multiple functional, advantage such as handle very skillfully.
Four, description of drawings:
Accompanying drawing is the utility model structural representation.
Five, embodiment:
Referring to accompanying drawing, supporter of the present utility model is the multi-functional cyclograph of a kind of sucked type, mainly comprise the compasses body, Casing with pen, supporter and handle, it is characterized in that supporter is the index dial (1) that a kind of surface has 360 degree, and the bottom has the bracing or strutting arrangement (3) of rubber suction cups (2), bracing or strutting arrangement (3) is connected with screw (5) with a shrinkage-rule (4) that has scale, one end of shrinkage-rule (4) has pointer (6), and the other end that has handle (7) is equipped with slidable Casing with pen (8) and figure pin (9) is housed above the screw (5), and has the pin cap above the figure pin (9).
The utility model adopts rubber suction cups (2) to make the center fixation point, the shrinkage-rule (4) that is contained on the sucker (2) can be selected arbitrary scale as drawing circle, and a slidably Casing with pen (8) is housed on shrinkage-rule (4), pen just can draw your needed circle, semicircle, ellipse are loaded onto in the inside on the plate face, be printed on the angulation yardstick above the sucker (2) simultaneously, have pointer (6), the required angle of can drawing on shrinkage-rule (4) and sucker (2) point of fixity.
Rubber suction cups (2) diameter is generally the 48-64 millimeter in addition, and its absorption weight is about 0.5～2 kilogram, and sucker (2) is connected by screw (5) with shrinkage-rule (4), and figure pin (9) is equipped with in order to using in screw (5) top on plank, mix the pin cap, in order to stabbing.Its length of shrinkage-rule of the present utility model (4) is generally 300～600 centimetres, pen clip ring (8) is 5～20 millimeters of Φ, can adopt spring or screw fixed formula, all can freely chalk or pencil etc. be loaded onto or withdraw from, because the utility model has adopted the principle of pull of vacuum, have when using accurately and the function of selecting scale and angle elastically, can not only in teaching, use, and can on Graphing of Engineering or other field, be extensive use of.
Claims (2)
1. multi-functional cyclograph of sucked type, mainly comprise compasses body, Casing with pen, supporter and handle, it is characterized in that supporter is the index dial (1) that a kind of surface has 360 degree, and the bottom has the bracing or strutting arrangement (3) of rubber suction cups (2), bracing or strutting arrangement (3) is connected with screw (5) with a shrinkage-rule (4) that has scale, one end of shrinkage-rule (4) has pointer (6), and the other end that has a handle (7) is equipped with slidable Casing with pen (8).
2. the multi-functional cyclograph of sucked type according to claim 1 is characterized in that, figure pin (9) is housed above the described screw (5), and has the pin cap above the figure pin (9).
