Abstract
The utility model provides a compasses ruler, forms the recess including the ruler that has the scale, ruler along scale orientation arch, and the recess corresponds chi body zero graduation department is equipped with the through -hole, but is equipped with the coupling bar of free rotation in the through -hole, and the coupling bar bottom is through a pivot top of connecting the back shaft, and the bottom of back shaft is equipped with the sucking disc, be equipped with the spout in the middle of the recess, spout initiating terminal and through -hole intercommunication, the terminal chi body maximum scale that corresponds of spout is equipped with the slider in the spout, and the slider top is equipped with scale pointer, and the painting brush dead lever is connected through pivot no. 2 in the slider bottom, and painting brush dead lever bottom is equipped with the painting brush fixation clamp. The utility model discloses can combine together compasses and ruler, both have measurement function, required radial circle can conveniently draw up again.
Description
Technical field
The utility model relates in one, primary school's drawing instrument, a kind of mathematics compass for drawing chi of special design.
Background technology
As everyone knows, compasses and ruler are drawing instruments necessary in mathematics studying, at present, the compasses that market is sold and ruler are all independently, larger space is taken during placement, and the bowlder that regular length radius drawn by compasses needs first to be undertaken measuring the distance determining compasses two ends by ruler, causes and uses inconvenience.
Summary of the invention
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: provide a kind of compasses combined with ruler, compasses and rule can be combined, both have measurement function, conveniently can draw again the circle of required radius.
The purpose of this utility model is realized by following technical measures:
A kind of compasses combined with ruler, comprise the graduated ruler of band, groove is convexed to form along scale direction in the middle part of ruler, the corresponding described ruler zero graduation place of described groove is provided with through hole, coupling bar free to rotate is provided with in described through hole, described coupling bar bottom connects the top of back shaft by rotating shaft one, the bottom of described back shaft is provided with sucker; Chute is provided with in the middle of described groove, described chute initiating terminal is communicated with through hole, the corresponding ruler maximum scale of described chute end, slide block is provided with in described chute, described slide block top is provided with tuning drive gear, described slide block bottom connects paintbrush fixed bar by rotating shaft two, and described paintbrush fixed bar bottom is provided with paintbrush geometrical clamp.
As a kind of improvement project, described rotating shaft one is parallel with ruler width.
As a kind of improvement project, described rotating shaft two is parallel with ruler width.
The beneficial effects of the utility model are: the utility model integrates ruler and compasses two kinds of drawing functions, slide block is provided with tuning drive gear, use and tuning drive gear is transferred to corresponding scale, in paintbrush geometrical clamp, put into pencil or chalk, the circle of regular length radius can be drawn easily.
Rotating shaft one and rotating shaft two are all parallel with ruler width, can put into ruler groove, using as common ruler when not using as compasses by inwardly folding to back shaft and paintbrush fixed bar, easy to operate and take up room little.

Fig. 1 is the utility model compasses combined with ruler ruler front view.
Fig. 2 is the utility model compasses combined with ruler A-A place schematic diagram.
Fig. 3 is the B direction view of the utility model compasses combined with ruler ruler 1.
In figure: 1-ruler, 2-groove, 3-through hole, 4-coupling bar, 5-rotating shaft one, 6-back shaft, 7-sucker, 8-chute, 9-slide block, 10-tuning drive gear, 11-rotating shaft two, 12-paintbrush fixed bar, 13-paintbrush geometrical clamp.
Detailed description of the invention
As shown in Figure 1, this practical a kind of compasses combined with ruler, comprise the graduated ruler 1 of band, ruler 1 convexes to form groove 2 along scale direction, groove 2 corresponding ruler 1 zero graduation place is provided with through hole 3, be provided with coupling bar 4 free to rotate in through hole 3, coupling bar 4 bottom connects the top of back shaft 6 by rotating shaft 1, and the bottom of back shaft 6 is provided with sucker 7; Chute 8 is provided with in the middle of groove 2, chute 8 initiating terminal is communicated with through hole 3, maximum scale on the corresponding ruler 1 of chute 8 end, slide block 9 is provided with in chute 8, slide block 9 top is provided with tuning drive gear 10, slide block 9 bottom connects paintbrush fixed bar 12 by rotating shaft 2 11, and paintbrush fixed bar 12 bottom is provided with paintbrush geometrical clamp 13.
Pencil or chalk can be put in paintbrush geometrical clamp 13 when using as compasses, tuning drive gear 10 is transferred to corresponding scale, the circle of regular length radius can be drawn.
Rotating shaft 1 and rotating shaft 2 11 are all parallel with ruler width, back shaft 6 and paintbrush fixed bar 12 can be rotated the groove putting into ruler, reducing and taking up room, using as common ruler when not using compasses.
Above-described embodiment is the utility model better embodiment, but enforcement of the present utility model is not restricted to the described embodiments, and the not detailed description part of the utility model is known technology.
