For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of multifunction flexible rule compasses; Comprise the compasses body; The line spare of doing that the compasses body comprises the centering part in the fixing center of circle and draws the circle line; It is characterized in that: described compasses body also includes the tape device that telescopic adjustment is confirmed the radius of circle of doing, and said tape device connects the centering part and makes line spare and realize that through the tape device telescopic adjustment centering part and the distance adjustment of making line spare constitute institute's radius of circle of doing and regulate, and said tape device comprises flexible rule box and is loaded in the flexible rule box and the scalable tape measure that closes in the flexible rule box.
Technique scheme is provided with down, adopts tape device to connect and feels relieved part and make line spare, and tape device has advantage easy to carry simple in structure, and radius length is big, and can directly read radius through tape measure, and is easy to use.
The utility model further is set to: described centering part is fixed on the flexible rule box, makes line spare and is located at tape measure and is connected with respect to the other end with the fixing end of flexible rule box.
Through adopting technique scheme, the centering part is installed on the heavier flexible rule box of quality, make line spare and be located on the telescopic tape measure, convenient when doing the circle operation.
The utility model further is set to: described centering part and to make line spare be the bearing setting be inserted with magnet in the centering part inner ring, and magnet exceeds inner ring.
Through adopting technique scheme, centering part and to make line spare be the bearing setting, bearing have and rotate advantage flexibly, and it is easy and simple to handle to draw, is provided with down so simultaneously, and the compasses structure is provided with conveniently, is convenient to draw materials, and making simply; Centering part inner ring is provided with magnet and confirms the center of circle, accomplishes location, the center of circle through magnet absorption, and is simple to operate.
The utility model further is set to: described flexible rule box is provided with the fixedly tape measure keeper of tape measure.
Through adopting technique scheme, tape measure keeper realization radius is confirmed the just no longer effect of change of back, makes the work circle more accurate.
The utility model further is set to: described tape measure is the fiber tape measure.
Through adopting technique scheme, the fiber tape measure is soft, can not accidentally injure the user.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the multifunction flexible rule compasses structural representation of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1, the disclosed a kind of multifunction flexible rule compasses of the utility model comprise the compasses body, the compasses body comprise the fixing center of circle centering part 1, draw the tape device 3 that line spare 2 and telescopic adjustment are confirmed the radius of circle of doing of doing of circle line; Said tape device 3 connects centering part 1 and makes line spare 2 and realize that through tape device 3 telescopic adjustment centering part 1 and the distance adjustment of making line spare 2 constitute institute's radius of circle of doing and regulate; Said tape device 3 comprises flexible rule box 30; Through injection moulding formation axis 301, be arranged with disc spring 32 (clockwork spring) on the axis 301 in the flexible rule box 30, fixing tape measure 31 on the disc spring 32; Tape measure 31 is the fiber tape measure; Certainly also can adopt steel tape, but steel tape is accidentally injured the user easily, so the preferential fiber tape measure that adopts; Axis 301 upper ends are release member 34 fixedly; Release member 34 is positioned at disc spring 32 tops and cooperates 32 folding and unfoldings of control disc spring with disc spring 32; Tape measure 31 1 ends are fixed on disc spring 32; And passing through the automatic winding that disc spring 32 rollings realize tape measure 31, tape measure 31 other ends stretch out through the perforate 302 of offering on flexible rule box 30 sidewalls, and line spare 2 is made in this end connection; Fixed installation centering part 1 on the said flexible rule box 30.As the feasible technical scheme of the utility model, centering part 1 can be arranged on the tape measure 31, makes line spare 2 and is installed on the flexible rule box 30; But be provided with down like this, when operating, need be with flexible rule box 30 motions, exist operation constant, be connected on the tape measure 31 so line spare 2 is made in the preferential employing of the utility model, centering part 1 is installed on the flexible rule box 30.
In this specific embodiment, described centering part 1 comprises bearing 11, and bearing 11 outer rings are fixedly connected with flexible rule box 30, plug magnet 10 in the inner ring, and bearing 11 inner rings are stretched out in magnet 10 ends, and magnet 10 ends are provided with cursor, and cursor is an indication piece of accurately confirming the center of circle; Make line spare 2 and be the bearing setting.Be provided with down like this, bearing has and rotates advantage flexibly, and the operation of being convenient to draw is accomplished smoothly and institute maps accurate.
For further making mapping accurately, described flexible rule box 30 is provided with the fixedly tape measure keeper of tape measure 31.The tape measure keeper can in this specific embodiment, adopt positioning rope 33 to be provided with for the clamping screw of perforate 302 1 sides of being located at flexible rule box 30, alignment pin etc.; Positioning rope 33 two ends are separately fixed on the tape measure box body 30; Axis 301 upper ends of flexible rule box 30 are arranged with release key 34, and positioning rope 33 middle parts are pressed on the release key 34, in order to decide tape measure 31; Radius is confirmed the just no longer effect of change of back, makes it more accurate.
In use, at first confirm the center of circle, the bearing of confirming the center of circle (centering part 1) is put above that; Through magnet be adsorbed on the blackboard or on the required plate and paper of drawing a picture (the below pad is established iron), or staff is pinned release key 34 then by press fit; Discharge graduated tape measure 31,, use positioning rope 33 release member 34 stationary positioned according to required definite length; Again drawing tools is put into another bearing (making line spare 2), begin mapping at last.All kinds of compasses of solution of so just having realized the novel bow compass of the utility model must be measured radius by ruler, and it is limited to draw radius of a circle, and general compasses cannot be directly on ground, the purpose of the technical problem of wall upper drawing circle.
Above-mentioned specific embodiment only is used to explain the usefulness of the utility model; It is not restriction to the utility model; Under the guidance of the utility model connotation, also can make corresponding distortion or modification, like, centering part and do also pen clip can be set on the bearing of line spare; Pilot pin be provided with etc. and feel relieved part and make line spare and can adopt that other rotor is provided with etc. is so all technical schemes that are equal to all fall in the protection category of the utility model.
