Abstract

The utility model relates to a readable type extensible compass. The readable type extensible compass is composed of a compass head, a left supporting leg, a left extensible supporting leg, a right supporting leg, a right extensible supporting leg, a dial and an indicator. The left supporting leg is arranged at the left end of the compass head, and the right supporting leg is arranged at the right end of the compass head. The left extensible supporting leg is arranged at the lower end of the left supporting leg, and the dial is arranged at the front end of the left supporting end. The right extensible supporting leg is arranged at the lower end of the right supporting leg, and the indicator is arranged at the front end of the right supporting leg. The readable type extensible compass can be used for drawing a circle and also used for reading out the diameter of the circle, and meanwhile, the supporting legs can be adjusted flexibly according to the size of the circle to be drawn, and the readable type extensible compass is simple in structure, convenient to use and suitable for students and designers.

Description

Readable numerical expression retractility compasses
Technical field
The utility model relates to a kind of compasses, especially a kind of readable numerical expression retractility compasses.
Background technology
Compasses are the instruments of draw circles or string in mathematics and drawing, are usually used in construction with ruler and compasses.Compasses make normally metal, comprise that two parts connect by a hinge, wherein can adjust.Compasses divide common compasses, bow-spring compasses, drop bow, trammel etc.Compasses are made of nib, rotating shaft, compasses supporting leg, lattice chi, hinged joint, handwriting, nib, compasses point, microtia, the upper end that is connected handwriting is inserted in its written lower end, the lower end of the formation of handwriting compasses is threaded in the upper end of nib, the concordant end of microtia is welded in the middle of the outside of compasses supporting leg, and the lower end of compasses supporting leg clamps the upper end that is connected the compasses point.It is characterized in that: the one side of handwriting is pasted the one side that is connected hinged joint, and the another side of hinged joint is pasted and is connected in the middle of the end of lattice chi, and the two ends that are connected rotating shaft are inserted in both sides, the crack of handwriting upper end, and the axis body of rotating shaft wears the upper end that is connected the compasses supporting leg.
Development along with society, computer is closely related with many work of people, aspect drawing, show, many mapping softwares have successively appearred, bring many convenience to people, mapping softwares such as two dimension, three-dimensional are wherein arranged, and no matter how how powerful and convenient the mapping software of computer is, and it is instead of manual drawing fully all.Compasses are a kind of important manual drawing instruments, but existing compasses drawing can not reflect diameter of a circle that we paint very intuitively.
The utility model content
In order to overcome the deficiency of above-mentioned existing compasses, the purpose of this utility model is to provide a kind of readable numerical expression retractility compasses, and it adopts and is provided with dial at the left branch leg front end, and right supporting leg front end is provided with pointer.
In order to realize that the technical scheme that the purpose of this utility model adopts is: a kind of readable numerical expression retractility compasses, it is characterized in that: it is made of compasses head, left branch leg, left telescopic outrigger, right supporting leg, right telescopic outrigger, dial, pointer; Described compasses head left end is provided with left branch leg, and right-hand member is provided with right supporting leg; Described left branch leg is square shape, and the lower end is provided with left telescopic outrigger, and front end is provided with dial; Described right supporting leg is square shape, and the lower end is provided with right telescopic outrigger, and front end is provided with pointer.
The beneficial effects of the utility model are: it can be used for picture circle, can read drawn diameter of a circle again, simultaneously can be according to the big or small telescopic outrigger of drawn circle, and simple in structure, easy to use, be suitable for student and designer.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the utility model structure chart
Fig. 2 is the utility model upward view
Fig. 3 is the utility model transverse sectional view
Fig. 4 is the utility model vertical cross-sectional
1-compasses head, 2-dial, 3-left branch leg, 4-left side telescopic outrigger, 5-compasses point, the right supporting leg of 6-, 7-pointer, 8-screw, the right telescopic outrigger of 9-, 10-propelling pencil among the figure.
The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, first embodiment shown in Figure 4, a kind of readable numerical expression retractility compasses, it is characterized in that: it is made of compasses head, left branch leg, left telescopic outrigger, right supporting leg, right telescopic outrigger, dial, pointer; Described compasses head left end is provided with left branch leg, and right-hand member is provided with right supporting leg; Described left branch leg is square shape, and the lower end is provided with left telescopic outrigger, and front end is provided with dial; Described right supporting leg is square shape, and the lower end is provided with right telescopic outrigger, and front end is provided with pointer.
In Fig. 1, Fig. 2, Fig. 3, second embodiment shown in Figure 4, described compasses head lower end is provided with groove, is used for being convenient for people to use; The lower end of described left branch leg and right supporting leg is respectively equipped with groove, and the left branch leg upper end is connected with compasses head by rotating shaft with right supporting leg upper end, and can rotate around the axis respectively; The left end of described dial is connected with left branch leg, and front end is provided with groove, and is provided with different numerical value in the top and bottom of groove; Described pointer, when right supporting leg when the rotating shaft that is connected with compasses head is rotated, pointer will slide in the groove of dial front end, be used for pointing out reading; Described left telescopic outrigger and right telescopic outrigger upper end are enclosed within respectively in the groove of left branch leg and right supporting leg lower end, and left telescopic outrigger lower end is provided with the compasses point, and right telescopic outrigger lower end is provided with propelling pencil, for increasing the length of left branch leg and right supporting leg; Be provided with pencil-lead in the described propelling pencil, can regulate the length that pencil-lead stretches out very easily; Described screw is made as two, is separately positioned on the lower end of left branch leg and right supporting leg, is used for fixing left telescopic outrigger and right telescopic outrigger.
When using the utility model, the pencil-lead of at first packing in the propelling pencil, again left branch leg and right supporting leg are closed up, regulate the length that pencil-lead stretches out, making pencil-lead can draw close with compasses point lower end is in the same place, begin the picture circle then, when left telescopic outrigger and right telescopic outrigger stretch out the most in short-term, the numerical value of our reading pointer indication dial front end groove upper end, when left telescopic outrigger and right telescopic outrigger stretch out when the longest, the numerical value of our reading pointer indication dial front end groove lower end, simple in structure, easy to use.
