Abstract
The utility model relates to a movable ruler, it is including the main scale that has the spout, by two side rulers that the pin overlaps in the two sides of main scale one end is equipped with the spout at the middle part, by another pin overlaps in two sides of main scale spout have two of spout to attach the chi, at the gauge needle of main scale tip, at the pen socket of a side ruler tip, at the inboard cushion in both sides chi both ends, be located two adjacent side rulers and attach the chi spout in link these two side rulers and attach the pin of chi. It can be used as both ruler and compasses, as well as angular bisector, and for displaying triangle and quadrangle, etc. it has the feature of multipurpose.
Description
(1) technical field
The utility model relates to a kind of instrument of drawing geometric figures, particularly a kind of movable ruler.
(2) background technology
The geometric instruments such as straight line, circle, triangle, quadrangle of drawing at present mostly are single chi or rule, often need to use multiple instrument, simultaneously, existing compasses are drawn circle, because bipod has only a fixing point, when firmly big, the angle of bipod easily changes, and mapping is inaccurate.
(3) utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of existing single drawing tool, provide a kind of and can draw circle, straight line, triangle, quadrangle, divide angle equally, draw circle accurate, can show the drawing tool of triangle, quadrangle character.
The technical scheme that realizes the utility model purpose is: it comprises the main scale that has chute, the two sides that is placed in main scale one end by pin are provided with two side chis of chute at the middle part, there is chute on the two sides that is placed in the main scale chute by another pin at the middle part two attached chis, at the rule pin of main scale end, at the pen cap of a side ruler end part, at the cushion block of inboard, chi two ends, both sides, be positioned at the pin that two sides adjacent chis and attached chi chute link this both sides chi and attached chi.
Because said structure of the present utility model, side chi and attached chi can with main scale harvest straight line, make chi and use; Utilize the side chi combination of the main scale and the band pen cap, make rule usefulness, the binding of attached chi is arranged simultaneously, the angle that the bipod that can guarantee to advise constitutes remains unchanged; The pin of slip in chute can constitute various triangular, quadrangle; The knowledge of utilizing the diagonal of rhombus to divide one group of diagonal angle or equivalent of triangle equally is divided angle etc. equally.
(4) description of drawings
Fig. 1 is the utility model deployed condition front view;
Fig. 2 is the utility model harvest linear state left view.
(5) specific embodiment
Be described further below in conjunction with accompanying drawing, but be not limited only to this.
As shown in Figure 1, 2, one of implementation of the present utility model is:
It comprises the main scale 3 that has chute, the two sides that is placed in main scale 3 one ends by pin 10 is provided with the side chi 1 and 5 of chute at the middle part, there is the attached chi 2 and 4 of chute on the two sides that is placed in main scale 3 chutes by pin 11 at the middle part, rule pin 14 in main scale 3 ends, the pen cap 15 in side chi 5 ends, cushion block 6 and 7 in inboard, side chi 1 two ends, cushion block 8 and 9 in inboard, side chi 5 two ends, be positioned at the pin 12 that side chi 1 and attached chi 2 chutes link side chi 1 and attached chi 2, be positioned at the pin 13 that side chi 5 and attached chi 4 chutes link side chi 5 and attached chi 4.
Claims (1)
1, a kind of movable ruler is characterized in that: it comprises the main scale (3) that has chute, the two sides that is placed in main scale (3) one ends by pin (10) is provided with side chi (1) and (5) of chute at the middle part, there are attached chi (2) and (4) of chute on the two sides that is placed in main scale (3) chute by pin (11) at the middle part, rule pin (14) in main scale (3) end, the pen cap (15) in side chi (5) end, cushion block (6) and (7) in side chi (1) inboard, two ends, cushion block (8) and (9) in side chi (5) inboard, two ends, be positioned at the pin (12) that side chi (1) and attached chi (2) chute link side chi (1) and attached chi (2), be positioned at the pin (13) that side chi (5) and attached chi (4) chute link side chi (5) and attached chi (4).
