Abstract
The invention relates to the field of stationery, in particular to a straight ruler with a function of a pair of compasses. The straight ruler comprises a body. The straight ruler is characterized in that a through hole groove is formed in the middle of the body, a locating shaft is arranged below the zero scale mark on the obverse side of the body, and a cylindrical pin hole which penetrates through the locating shaft and the body is formed in the center of the locating shaft; a nut is installed at the upper end of the locating shaft, and a locating pin is arranged in the nut; and a sliding block is installed in the through hole groove, and a circular hole which enables a pencil to be inserted into is formed in the center of the sliding block. The straight ruler is simple in structure, convenient to use and carry and suitable for extensive popularization and application, and saves the space, the function of the straight ruler and the function of the pair of compasses are integrated, and the straight ruler can be used for drawing straight lines and also be used for conveniently drawing circles with the appointed radius sizes.
Description
(1) technical field
The present invention relates to field of stationery, particularly a kind of ruler with calipers function.
(2) background technology
At present; student is at graphing; usually can use ruler and compasses; ruler is wherein utilized to draw straight line; utilize compasses to draw circular or circular arc, both functions are different, sometimes also need to be combined; the bowlder such as drawing predetermined radius length needs the distance measured with a yardstick out between compasses bipod, carry with use all very inconvenient.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of ruler with calipers function, ruler functions and calipers function is become one, and structure is simple, easy to use, be easy to carry.
The present invention is achieved through the following technical solutions:
Have a ruler for calipers function, comprise body, it is characterized in that: scale is carved with on a long limit of body, the centre of body is provided with the through hole groove that a cross section is " ten " font, and through hole groove is parallel with the scale face of body; The below of body front " 0 " graduation mark is provided with columniform locating shaft, locating shaft center is provided with the cylindrical pin hole of through locating shaft and body, the center of circle of pin hole overlaps with the intersection point of " 0 " graduation mark and through hole groove axis, locating shaft outer surface is provided with external screw thread, locating shaft upper end is provided with nut, be provided with the pilot pin that to cooperatively interact with pin hole in nut, pilot pin moves up and down with cap rotation; Be provided with columniform slide block in through hole groove, slide block is provided with the fixture block cooperatively interacted with through hole groove, and its center is provided with the circular hole that can be inserted pencil, and the outer surface of slide block is provided with external screw thread and is provided with holding screw, and upper end of slide block is provided with tuning drive gear.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to use, ruler functions and calipers function are become one, can straight line be drawn, the circle of specifying radius size can easily be drawn again, and be easy to carry, save space, be suitable for wide popularization and application.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
Fig. 2 is locating shaft cross section structure schematic diagram of the present invention.
Fig. 3 is slide block cross section structure schematic diagram of the present invention.
In figure, 1 body, 2 scales, 3 through hole grooves, 4 locating shafts, 5 slide blocks, 6 pin holes, 7 nuts, 8 pilot pins, 9 circular holes, 10 fixture blocks, 11 tuning drive gears, 12 holding screws, 13 pencils.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises body 1, it is characterized in that: scale 2 is carved with on a long limit of body 1, and the centre of body 1 is provided with the through hole groove 3 that a cross section is " ten " font, and through hole groove 3 is parallel with the scale face of body 1; The below of body 1 front " 0 " graduation mark is provided with columniform locating shaft 4, locating shaft 4 center is provided with the cylindrical pin hole 6 of through locating shaft 4 and body 1, the center of circle of pin hole 6 overlaps with the intersection point of " 0 " graduation mark and through hole groove 3 axis, locating shaft 4 appearance is provided with external screw thread, locating shaft 4 upper end is provided with nut 7, be provided with the pilot pin 8 that to cooperatively interact with pin hole 6 in nut 7, pilot pin 8 rotates with nut 7 and moves up and down; Columniform slide block 5 is installed in through hole groove 3, slide block 5 is provided with the fixture block 10 cooperatively interacted with through hole groove 3, slide block 5 center is provided with the circular hole 9 that can be inserted pencil 13, slide block 5 lower end is parallel with body 1 bottom surface, slide block 5 upper end is given prominence to outside body 1, the outer surface of slide block 5 upper end is provided with external screw thread and is provided with holding screw 12, and slide block 5 upper end is provided with tuning drive gear 11 towards the one side of scale 2.
During use, pilot pin 8 rotates outside body 1 by first rotary nut 7, then sliding slider 5 sets the radius needed for picture circle according to the scale that tuning drive gear 11 indicates, and then screws holding screw 12, the last pencil 13 that inserts in circular hole 9 rotates along pilot pin 8, can draw required circle.
Structure of the present invention is simple, easy to use, ruler functions and calipers function is become one, and can draw straight line, can easily draw again the circle of specifying radius size, and be easy to carry, and saves space, is suitable for wide popularization and application.
