Abstract

The utility model relates to combined compasses with measuring function, which mainly comprises a circle center leg component 1 and a drawing leg component 2. The circle center leg component 1 includes a central shaft 1.1, an anchorage clip 1.2 and a circle center needle 1.3. The anchorage clip 1.2 includes an upper cover 1.2.1, a lower cover 1.2.2 and a fastening screw 1.2.3. The drawing leg component 2 includes a stainless steel ruler 2.1. A hollowed-out groove 2.2 is arranged in the middle of the ruler 2.1. Scales are marked on the edges of the two external sides of the upper surface of the ruler 2.1 and the edges of the two internal sides close to the hollowed-out groove 2.2. A pen socket 2.4 is fixed at one end of the ruler 2.1. A line drawing pen 2.5 is arranged in the pen socket 2.4. The utility model has the advantages that the distance between the two legs is not required to be measured when the combined compasses are used for drawing a circle, the detached circle center leg component and the drawing leg component can be respectively used as a probe and a ruler, and the combined compasses can be stored and carried conveniently.

Description

The combined type compasses

Technical field:

The utility model relates to a kind of stationery, especially a kind of combined type compasses.

Background technology:

Compasses are one of the most frequently used drawing tools, traditional compasses comprise Gauge for the centre of a circle pin and mapping rule pin, the upper end of Gauge for the centre of a circle pin and mapping rule pin is riveted together, when drawing than great circle or circular arc, Gauge for the centre of a circle pin and mapping rule pin will open bigger angle, thereby cause Gauge for the centre of a circle pin and mapping rule pin to tilt on paper, drawing not only relatively like this, effort also can influence precision; And traditional compasses function singleness, no measurement function in use also must cooperate with ruler, can not satisfy people's needs.

The utility model content:

The technical problems to be solved in the utility model is: provide a kind of subsidiary measurement function and the combined type compasses accurately of drawing.

For realizing that above-mentioned technical problem the technical solution of the utility model is:

This combined type compasses comprise Gauge for the centre of a circle pin assembly and mapping rule pin assembly, Gauge for the centre of a circle pin assembly comprises central shaft, anchorage clip and center of circle pin, a center of circle pin is installed in the lower end of central shaft, anchorage clip comprises loam cake, lower cover and holding screw, the loam cake of anchorage clip is vertically fixed on the central shaft of upper end of center of circle pin, the lower cover of anchorage clip is free, and anchorage clip following covered two circular holes; Mapping rule pin assembly is made up of scale and the pen cap, detail pen that a centre has hollow slots, and an end of scale is installed the pen cap, and detail pen is arranged in the pen cap.

Two outer ledges of the scale upper surface of described mapping rule pin assembly and two inside edges of close hollow slots indicate the length scale.

After adopting technique scheme, the beneficial effects of the utility model are:

It is convenient that Gauge for the centre of a circle pin assembly and mapping rule pin combination of components are decomposed, the central shaft of combination back Gauge for the centre of a circle pin assembly is vertical mutually with the scale of mapping rule pin assembly, therefore when mapping detail pen and center of circle pin all perpendicular to paper, can very easily draw the bigger garden of radius, and drawing bowlder, no longer need directly can read radius of a circle, make the picture circle become convenient and easy to operate measuring between the compasses two rule pin; After finishing using, can split Gauge for the centre of a circle pin assembly and mapping rule pin assembly, Gauge for the centre of a circle pin assembly after the fractionation and mapping rule pin assembly can be done probe and ruler respectively separately and use, and are fit to deposit and carry.

Description of drawings:

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the surface structure schematic diagram of a specific embodiment of this combined type compasses.

Fig. 2 is the Gauge for the centre of a circle pin modular construction schematic diagram of a specific embodiment of this combined type compasses.

Fig. 3 is the mapping rule pin modular construction schematic diagram of a specific embodiment of this combined type compasses.

The specific embodiment:

As Fig. 1, Fig. 2, shown in Figure 3: this combined type compasses mainly comprise Gauge for the centre of a circle pin assembly 1 and mapping rule pin assembly 2, Gauge for the centre of a circle pin assembly 1 comprises central shaft 1.1, anchorage clip 1.2 and center of circle pin 1.3, central shaft 1.1 is cylinders made from stainless steel, and the lower end of central shaft 1.1 is center of circle pins 1.3 making with its one-shot forming; Anchorage clip 1.2 comprises loam cake 1.2.1, lower cover 1.2.2 and holding screw 1.2.3, and the loam cake 1.2.1 of anchorage clip is vertically fixed on the central shaft 1.1 of upper end of center of circle pin 1.3, and the lower cover 1.2.2 of anchorage clip is free, and two circular holes are arranged on the lower cover 1.2.2 of anchorage clip.Mapping rule pin assembly 2 comprises a stainless steel scale 2.1, have a hollow slots 2.2 in the middle of the scale 2.1, two inside edges of two outer ledges of scale 2.1 upper surfaces and close hollow slots 2.2 indicate length scale 2.3, so that measure the radius in drawn garden and work as a common ruler use.One end of scale 2.1 installs and fixes the pen cap 2.4, and detail pen 2.5 is arranged in the pen cap 2.4.

When assembling this combined type compasses, the central shaft 1.1 of Gauge for the centre of a circle pin assembly 1 is pierced into the lower cover 1.2.2 that puts anchorage clip after the hollow slots 2.2 of scale 2.1 again, tightened holding screw 1.2.3 just.When the bowlder of drawing different radii, unscrew holding screw 1.2.3, the position of suitably adjusting scale 2.1 according to scale gets final product.When depositing and carrying this combined type compasses, Gauge for the centre of a circle pin assembly 1 and mapping rule pin assembly 2 are split, can put in the writing case easily, and central shaft 1.1 and center of circle pin 1.3 can make probe and use, scale 2.1 can work as the ruler use.
