Abstract
The utility model discloses an angle drawing device comprising a dial and an indicator, wherein an indicator sliding device is arranged at the tail end of the indicator; the indicator is provided with an arc drawing hole; the arc drawing hole can slide up and down along the indicator; and a fixed press button is arranged on the arc drawing hole. According to the angle drawing device, the dial is provided with the indicator, and the indicator sliding device and the arc drawing hole are arranged on the indicator and the middle part of the whole angle drawing device is a hollow part. When people need to measure the degree of one angle, the bottom edge of the angle drawing device is overlapped with one edge of the angle, and then the indicator sliding device is slipped by fingers to overlap the indicator with the other edge of the angle, so that the degree of one angle can be accurately measured. The angle drawing device disclosed by the utility model can be used as an angle measuring device and also can be used as a compass, so that the angle drawing device is very convenient to use; and the angle drawing device is a novel studying tool integrating the angle measuring device with the compass.
Description
Technical field
The utility model belongs to stationery technical field commonly used, particularly a kind of angle drawing device.
Background technology
In our study and work, often to use protractor, when particularly student's doing mathematics is inscribed, the number of degrees through a regular meeting angle of use amount hornwork amount.But if draw a circle or one section arc, will use compasses, and angle or the arc that will draw known number of degrees are used with regard to requirement hornwork and compasses.Two kinds of instruments rotating use pretty troublesome, also very inconvenient.So, design and produce compasses with protractor and to be in the same place, be a very necessary thing.
The utility model content
The utility model provides a kind of angle drawing device simple in structure, easy to use.
A kind of angle drawing device comprises dial and pointer, and said pointer end is provided with the pointer glider, and picture arc hole is set on the said pointer, and said picture arc hole can slide up and down along pointer, and said picture arc is provided with peg button on the hole.
Because the utility model angle drawing device is provided with pointer on dial, and on pointer, is provided with the pointer glider and draws the arc hole, and the centre of whole angle drawing device is a hollow parts.When we need measure the number of degrees at an angle, follow the one side at angle to overlap on the base of angle drawing device, use hand sliding pointer glider then, make pointer overlap the number of degrees that can accurately measure an angle with the another side at angle.When we need the arc of a known angle of picture; Only need the sliding pointer glider; Make the pointer of angle drawing device and angle that the base is formed equal the number of degrees at angle; Determine the length of arc radius and fix picture arc hole along pointer slip picture arc hole then, insert nib in the picture arc hole, the length of the arc that draws gets final product.This shows that the utility model angle drawing device both energy equivalent hornwork uses, can work as compasses again and use, and very easy to use, be a kind of novel learning tool that integrates protractor and compasses.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done explanation further:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1: a kind of angle drawing device, comprise dial 1 and pointer 2, said pointer 2 ends are provided with pointer glider 3, and picture arc hole 4 is set on the said pointer 2, and said picture arc hole 4 can slide up and down along pointer 2, on the said picture arc hole 4 peg button 5 is set.
The utility model angle drawing device is provided with pointer on dial, and on pointer, is provided with the pointer glider and draws the arc hole, and the centre of whole angle drawing device is a hollow parts.When we need measure the number of degrees at an angle, follow the one side at angle to overlap on the base of angle drawing device, use hand sliding pointer glider then, make pointer overlap the number of degrees that can accurately measure an angle with the another side at angle.When we need the arc of a known angle of picture; Only need the sliding pointer glider; Make the pointer of angle drawing device and angle that the base is formed equal the number of degrees of known angle; Determine the length of arc radius and fix picture arc hole along pointer slip picture arc hole then, insert nib and slide in the hole, the length of the arc that draws gets final product.This shows that the utility model angle drawing device both energy equivalent hornwork uses, can work as compasses again and use, and very easy to use, be a kind of novel learning tool that integrates protractor and compasses.
