Abstract
The utility model relates to a pair of moving compasses comprising a fixed rod, a scale transverse rod and a drawing pen, wherein a fixed lantern ring is arranged at one end of the scale transverse rod, and the fixed rod is sleeved in the fixed lantern ring; a sliding lantern ring is arranged on the scale transverse rod; a sliding button corresponding to the scale transverse rod is arranged on the front surface of the sliding lantern ring; the scale transverse rod penetrates in the sliding button; and the drawing pen is sleeved in the sliding lantern ring. Two supporting legs of the moving compasses are connected through the scale transverse rod, and the drawing trouble caused by the loosening of the connecting point at the end of the two supporting legs of the common compasses can be avoided. Moreover, the scale transverse rod can be used as a reference for compasses drawing specifications, so a dividing ruler is not needed, and the drawing is more convenient.
Description
Technical field
The utility model relates to a kind of stationery, relates in particular to the movable compasses that a kind of two supporting legs separate.
Background technology
Two supporting leg one ends of common compasses are fixedly connected, are central angle with the tie point, and two supporting legs are angled, and the distance between the end of two supporting legs is that radius is justified.In use, the tie point of two supporting legs of compasses often takes place loosening, influences the quality that we draw a picture like this, and the rule that compasses will cooperate could use, and is also pretty troublesome during use.
The utility model content
The compasses that the utility model provides a kind of two supporting legs to separate, two one of supporting legs are fixed bar, and one is paintbrush, and both connect by the cross bar of a band scale, fix loosening and trouble that cause with regard to having avoided common with two supporting legs of compasses like this.
The movable compasses of the utility model are achieved through the following technical solutions purpose:
A kind of movable compasses comprise fixed bar, scale cross bar and paintbrush, and wherein, described scale cross bar one end is provided with retaining collar, and described fixed bar is placed in the described fixed cover; Described scale cross bar is provided with slip collar, and described slip collar front is provided with and the described scale cross bar button that slides accordingly, and described scale cross bar is through at described slip and smashs, and described paintbrush is placed in the described slip collar.
Above-mentioned movable compasses, wherein, scale cross bar positive and negative all indicates the length scale.
Above-mentioned movable compasses, wherein, described slip collar internal diameter is greater than described paintbrush diameter, and described slip collar back is provided with hold-down screw.
Above-mentioned movable compasses, wherein, described retaining collar internal diameter is greater than described fixed bar diameter, and described retaining collar is provided with hold-down screw.
Above-mentioned movable compasses, wherein, described slip is buckled and is provided with hold-down screw.
Above-mentioned movable compasses, wherein, described fixed bar lower end is fixed with firm pin; Described fixed bar upper end is provided with footstalk.
Adopt the advantage of the movable compasses of the utility model to be:
1, two supporting legs of the movable compasses of the utility model connect by the scale cross bar, and having avoided common compasses is the trouble that mapping produces because of the termination fixed connection point of two supporting legs is loosening.
2, the scale cross bar of the utility model active type compasses can be used as the reference of compasses construction specification, needn't be using rule in addition, for trouble has been saved in mapping.
Description of drawings
Accompanying drawing 1 is the Facad structure schematic diagram of the movable compasses of the utility model.
The specific embodiment
As shown in Figure 1, the movable compasses of the utility model comprise fixed bar 1, scale cross bar 2 and paintbrush 3, and described scale cross bar 2 one ends are provided with retaining collar 4, and described fixed bar 1 is placed in the described retaining collar 4; Described scale cross bar 2 positive and negatives all indicate the length scale.Described scale cross bar 2 is provided with slip collar 5, described slip collar 5 fronts be provided with described scale cross bar slide accordingly the button 6, described scale cross bar 2 is through in the described slip button 6, realize that with this described slip collar 5 slides on described scale cross bar 2, described paintbrush 3 is placed in the described slip collar 5, determine distance between the described fixed bar 2 described paintbrushes 3 by the scale on the described scale cross bar 2, the i.e. radius of a circle that will do, described slip button 6 is provided with hold-down screw 7, be used for fixing described paintbrush 3 in the position of described scale cross bar 2, determine distance between described fixed bar 1 and the described paintbrush 3 with this.Described slip collar 5 internal diameters are greater than the diameter of described paintbrush 3.Described retaining collar 4 internal diameters are greater than the diameter of described fixed bar 1, and described retaining collar 4 is provided with hold-down screw 8, are used for fixing described fixed bar 1.Described fixed bar 1 lower end is fixed with firm pin 9; Described fixed bar 1 upper end is provided with footstalk 10.
Fig. 2 is the structure schematic diagram of movable compasses, and as shown in the figure, described slip collar 5 backs are provided with hold-down screw 11, are used for fixing described paintbrush 3.
During use, earlier described fixed bar 1 is inserted 4 kinds of described retaining collars, screw the end that described hold-down screw 8 is fixed in described fixed bar 1 described scale cross bar 2.Described paintbrush 3 is inserted in the described slip collar 5, screw described hold-down screw 11, size according to the circle that will do moves the relevant position of described paintbrush 3 to described scale cross bar 2, and screw described hold-down screw 7 described slip collar 5 is fixed, be that justify in the center of circle with described firm nail 9.After a circle was finished, loosening described hold-down screw 7 according to the size of the circle that will do, was regulated the distance between described paintbrush 3 and the described fixed bar 1.Repeat the above-mentioned step of drawing a picture.Be all over when drawing a picture, loosening described hold-down screw 8 and hold-down screw 11 take off described fixed bar 1 with described paintbrush 3, deposit respectively with described diligent cross bar 2.
Will be appreciated that; the above embodiments are only as the exemplifying and propose preferred embodiment of the movable compasses of the utility model; the movable compasses of the utility model also not only are confined to this, and the various simple modifications that those skilled in the art can implement also should fall in the protection domain of the movable compasses of the utility model.
