Abstract

The utility model relates to a pair of compasses, in particular to a pair of ruler type compasses self-provided with length measurement. The ruler compasses is provided with a plate body; a graduated scale is fixed and stuck on the long side of the plate body, or graduation lines are carved on the long side of the plate body; a long strip-shaped sliding slot is formed at the center of the graduated scale; a clamping slot is formed on the outer side at the lower end surface of the sliding slot; a sleeve is inserted in the sliding slot; an upper sliding seat and a lower sliding seat are fixed on the upper side and the lower side of the sleeve positioned in the sliding slot; and the lower sliding seat clamped in the clamping slot can slide left and right in the clamping slot. The ruler compasses has a simple structure, and is self-provided with the graduated scale; the radius can be rapidly adjusted; the ruler compasses cannot be influenced by external force when drawing a circle, has high graph drawing efficiency, and can serve as a pair of compasses as well as a ruler.

Description

Ruler formula compasses

One, technical field: the utility model relates to a kind of compasses, relates in particular to a kind of ruler formula compasses that carry linear measure longimetry.

Two, background technology: the apparatus that often uses when compasses are hand-drawing, the tradition compasses are herringbones, one pin supports, in a single day one pin rotary picture is round, needs the distance between the good bipod of adjustment before drawing circle, overexerts in drawing the circle process, the bipod spacing is easy to change, need adjustment spacing again, influence picture efficient and attractive in appearance, especially above-mentioned situation takes place in the large-scale educational compasses of teacher's use especially easily.

Three, summary of the invention: the purpose of this utility model is proposing a kind of picture circle fast, accurately, the ruler formula compasses that not influenced by external force.

The purpose of this utility model is achieved in that ruler formula compasses have a plate body, the fixing sticking glutinous rule that has on the long limit of plate body, or be carved with graduation mark, the rule center has the strip chute, the outside, chute lower surface has draw-in groove, is inserted with sleeve in chute, and the both sides up and down that sleeve is positioned at chute are fixed with upper and lower slide, lower slider is stuck in the draw-in groove, and can horizontally slip in draw-in groove.

The utility model is simple in structure, and self possesses rule, and it is quick to adjust radius, draws bowlder and not influenced by external force, picture efficient height.Can work as compasses and use, also can work as ruler and use.

Four, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:

Fig. 1 is ruler formula compasses structural representations;

Fig. 2 is a ruler formula compasses structure schematic diagram;

Fig. 3 is ruler formula compasses cutaway views.

Legend: 1, handle, 2, rule, 3, chute, 4, sleeve, 5, upper saddle, 6, card, 7, locking nut, 8, level meter, 9, setscrew nut, 10, plate body, 11, sucker, 12, lower slider, 13, draw-in groove.

Five, the specific embodiment:

The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.

Embodiment: as Figure 1-3, ruler formula compasses have a plate body 10, the fixing sticking glutinous rule 2 that has on plate body 10 long limits, or be carved with graduation mark, and rule 2 centers have strip chute 3, and the outside, chute 3 lower surfaces has draw-in groove 13, in chute 3, be inserted with sleeve 4, the both sides up and down that sleeve 4 is positioned at chute 3 are fixed with upper and

lower slide

5,12, and lower slider 12 is stuck in the draw-in groove 13, and can horizontally slip in draw-in groove 13.Plate body 10 left sides are semicircle, and its upper surface circle centre position is equiped with handle 1, and the lower surface circle centre position has hole clipping, and the upper end of sucker 11 is connected in the hole clipping, is connected with hole clipping is active.Plate body 10 upper end surfaces that are positioned at chute 3 right sides are inlaid with fluid level instrument 8.Rule 2 is made by transparent plastic material, and the zero graduation line on it overlaps in the orthographic projection of vertical direction with the center of circle of handle 1.On the plate body 10 below rule 2 middle parts, that is to say that the center of plate body 10 is inlaid with fluid level instrument 8.Fluid level instrument 8 is the coloured liquid of filling tape in sealed glass vessel, and be detained bubble is arranged, be decorated with lines at the middle part of glassware, in order to the sign bubble position, by the position of bubble in glassware, judge plate body 10 laterally, vertical level whether.The cylinder of sleeve 4 for connecting, the port place is fixed with card 6 thereon, and card 6 is the flexure strip of bending, it is fixed on sleeve 4 outer walls on one side, and another side is positioned at sleeve 4, is connected with locking nut 7 on sleeve 4 walls, locking nut 7 the inners are stretched in the sleeve 4, contact on card 6.On upper saddle 5, have a screwed hole, be connected with setscrew nut 9 in it, the screwing on, screw off of setscrew nut 9, promptly with the contacting of plate body 10, thus the fixing position of upper saddle 5 on plate body 10.

During use, chalk is inserted sleeve 4, and fixing by card 6, by sucker 11 plate body 10 is adsorbed on blackboard, desktop etc. subsequently and locates, regulate upper and

lower slide

5,12, determine the picture radius of circle, a hand-held handle 1, hand is stirred plate body 10 in addition, can finish the picture circle.

Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
