Abstract

The utility model discloses a pair of curved surface compasses, which belongs to a tool for drawing a circle (intersection line) on a curved surface and an irregular surface. Wherein, a handle is arranged on the upper end of a supporting leg, the top end of the handle is provided with a water level, a drawing leg is coated in a sliding sleeve on which a lock bolt is fixed, the upper and the lower end of the drawing leg are screwed with a screw cap and a pen clip, a drawing pen is fixed on the pen clip, a spring is respectively nested on the drawing leg between the sliding sleeve and the screw cap and the pen clip, a location hole is processed on a plane connecting rod, one end thereof is hinge-jointed with the supporting leg, and the other end thereof is fixed with the lock bolt on the sliding sleeve by the location hole. The utility model has high precision and good continuity when drawing circles (intersection lines).

Description

Camber compasses

Technical field

The utility model relates to a kind of Camber compasses, belongs on curved surface or the instrument of irregular surface upper drawing circle (intersection).

Background technology

Existing can be at the compasses of curved surface upper drawing circle, a kind of compasses of drawing intersection on the face of cylinder are disclosed as Chinese patent CN2149294y, it is adapted at drawing on the face of cylinder intersection, but when the irregular surface upper drawing circle, owing to supporting leg with draw the rigidity of leg and the reason such as uneven on drawn surface, be difficult to guarantee that supporting leg is parallel all the time with the picture leg in the setting-out process, simultaneously also be difficult to guarantee paintbrush corresponding fluctuating flexibly with the fluctuating on setting-out surface, be the excellent contact on paintbrush and drawn surface, this has just influenced the precision and the continuity of drawn circle.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Camber compasses is provided, and it can accurately draw circle (intersection) continuously on curved surface or irregular surface.

The purpose of this utility model is achieved in that it comprises supporting leg, draws leg, handle, paintbrush, and handle is installed in the supporting leg upper end, and handle top is installed spirit level; Draw the leg slip cap and be contained in the sliding sleeve, be fixed with two clamping screws on the sliding sleeve, draw the leg upper end and be screwed nut, draw the leg lower end and be screwed the pen card, pen card lower end is fixed with paintbrush, pocketed springs on the picture leg between nut and the sliding sleeve, pocketed springs on the picture leg between pen card and the sliding sleeve; Two planar linkage one ends and supporting leg upper articulation, whenever be separated by on it segment distance respectively correspondence be processed with several locating holes, the clamping screw on corresponding positioning hole and the sliding sleeve is fixed.

Compared with prior art, advantage of the present utility model is, because the rigidity of structure is good, and spirit level has been installed, can make supporting leg keep vertical, and with draw leg remain parallel because sliding sleeve is installed, can guarantee paintbrush and be drawn surperficial fine the contact, thereby make drawn circle and intersection accurately continuous.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Embodiment describes the utility model in detail below in conjunction with accompanying drawing.

Handle 10 is installed on the supporting leg 11 of the present utility model, and spirit level 9 is installed at handle 10 tops; Drawing leg 3 slip caps is contained in the sliding sleeve 13, be fixed with two clamping screws 5 on the sliding sleeve 13, draw leg 3 upper ends and be screwed nut 7, draw leg 3 lower ends and be screwed pen card 2, pen card 2 lower ends are fixed with paintbrush 1, pocketed springs 6 on the picture leg 3 of 13 of nut 7 and sliding sleeves, pocketed springs 4 on the picture leg 3 of 13 of pen card 2 and sliding sleeves; Two planar linkages 8 and supporting leg 11 upper articulations, whenever be separated by on it segment distance respectively correspondence be processed with several locating holes 12, corresponding positioning hole 12 is fixing with the clamping screw 5 on the sliding sleeve 13.

The utility model when work, with hand handle 10, twist supporting leg 11, make picture leg 3 around supporting leg 11 rotations, paintbrush 1 circle (intersection) that can on drawn surface, draw.When drawn surface undulation not at ordinary times, act on paintbrush 1, picture leg 3 is slided up and down in sliding sleeve 13, under the effect of spring 4 and spring 6, guaranteed that paintbrush 1 well contacts with drawn surface at any time, so guaranteed setting-out accurately continuously.According to drawn radius of a circle size, can change being connected of different locating hole 12 and sliding sleeve 13, sighting-level 9 is in order to judge and to regulate the perpendicularity on supporting leg 11 and drawn surface.

Claims

1. a Camber compasses comprises supporting leg, draws leg, handle, paintbrush, it is characterized in that:

Handle is installed in a, supporting leg upper end, and handle top is installed spirit level;

B, picture leg slip cap are contained in the sliding sleeve, are fixed with two clamping screws on the sliding sleeve, draw the leg upper end and are screwed nut, draw the leg lower end and be screwed the pen card, pen card lower end is fixed with paintbrush, pocketed springs on the picture leg between nut and sliding sleeve, pocketed springs on the picture leg between pen card and sliding sleeve;

C, two planar linkage one ends and supporting leg upper articulation, whenever be separated by on it segment distance respectively correspondence be processed with several locating holes, the clamping screw on corresponding positioning hole and the sliding sleeve is fixed.
