Abstract
The invention provides a pair of ruler compasses, which comprises a positioning support leg, wherein the positioning support leg is provided with a ruler which is connected with the positioning support leg through a shaft and can be rotated around the shaft; a locking groove is formed in the connecting position of the positioning support leg and the ruler; when the ruler is mutually perpendicular to the positioning support leg, the zero scale of the ruler is positioned just above a positioning pin; and the ruler is provided with a drawing bar which can be adjusted in a sliding way, and the drawing bar is sheathed on the ruler through a sliding sleeve which is provided with adjusting bolts. The pair of ruler compasses has the advantages of simple structure, convenience in use and carrying, higher performance-price ratio and space saving, the ruler and a pair of compasses are combined into a whole, and required circles can be conveniently drawn.
Description
Technical field
The present invention relates to a kind of stationery, especially a kind of compasses with measurement function.
Background technology
Compasses are in mathematics and drawing, it is the instrument of draw circles or string, be usually used in construction with ruler and compasses, existing compasses are drawn bowlder, must important affair measure out the distance between the compasses bipod with a yardstick, as radius, the end with pin is fixed on a place, as the center of circle, the end with pencil is rotated a circle.Cumbersome like this.
Summary of the invention
Technical problem to be solved by this invention is the defective for prior art, and a kind of compasses with measurement mechanism are provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of ruler compass, comprise positioning support leg, described positioning support leg is provided with ruler, ruler is connected with the positioning support leg axle, ruler can rotate around the axis, and described positioning support leg and ruler junction are provided with latch recess, when ruler is mutual vertical with positioning support leg, ruler " 0 " scale place is positioned at directly over the pilot pin, and ruler is provided with the drawing bar of slidably regulating.
Described drawing bar is enclosed within on the ruler by sliding sleeve, is provided with adjusting bolt on the sliding sleeve.
The present invention adopts above technical scheme to have following technique effect:
The present invention is simple in structure, easy to use, and cost performance is higher; The two unites two into one with ruler and compasses, can easily draw required circle, and be easy to carry, and is easy to use, saves the space.
Description of drawings
Fig. 1 is the structural representation of compasses of the present invention.
Among the figure: 1. positioning support leg; 2. ruler; 3. sliding sleeve; 4. drawing bar; 5. adjusting bolt.
The specific embodiment
Below, by reference to the accompanying drawings technical scheme of the present invention is described in further details.
Be a kind of ruler compass of the present invention among the figure, comprise positioning support leg, described positioning support leg is provided with ruler, ruler is connected with the positioning support leg axle, ruler can rotate around the axis, and described positioning support leg and ruler junction are provided with latch recess, when ruler is mutual vertical with positioning support leg, ruler " 0 " scale place is positioned at directly over the pilot pin, and ruler is provided with the drawing bar of slidably regulating.The drawing bar is enclosed within on the ruler by sliding sleeve, is provided with adjusting bolt on the sliding sleeve.
As long as make the accurate picture radius of a circle size that needs of the drawing pole pair of compasses just can easily draw required circle during use, ruler can be turned to the position parallel with positioning support leg when not in use.The present invention is easy to carry, and is easy to use, saves the space.
