Abstract

The utility model discloses a folding multifunctional drawing ruler which comprises two scale rulers. One scale ruler is used as a mother ruler and the other scale ruler is used as a son ruler. The son ruler is hinged on the mother ruler, so that the son ruler and the mother ruler can be folded. The folding multifunctional drawing ruler not only can be used for drawing common straight lines, a plurality of parallel lines and circular arcs, but also can be used for metering an angle, is convenient to carry and has the furthest characteristic of integrating multiple functions into one ruler.

Description

The folding utility drawing rule

Technical field

The utility model belongs to the stationery field, particularly relates to a kind of multifunctional drawing ruler.

Background technology

People usually use drawing instruments such as ruler, compasses, protractor, parallel rule when drawing.Drawing instrument function singleness commonly used, the drawing personnel need be equipped with multiple drawing instrument just can finish the drawing task.Be equipped with the multiple drawing instrument material resources that both wasted financial resources, also be difficult for preserving management.The patent of many multi-functional rulers is disclosed in the patent documentation both at home and abroad, as application number is 200620156927.5 to disclose a kind of multi-functional ruler, to rule, make an arc, function collection such as protractor is one, but its structure is comparatively complicated, the ruler of making is not sturdy and durable, thereby can not get wide popularization and application.

Summary of the invention

The purpose of this utility model is to make a kind of simple and practical multi-functional ruler, and functions such as ruler, compasses, parallel rule are combined together cleverly, can close and can divide, and is easy to process, easy to use, brought into play the characteristics that a chi is used more to greatest extent.

For achieving the above object, the technical scheme that the utility model is taked is: it comprises two scale rulers, the female chi of conduct, and one sub-chi is hinged on female chi as sub-chi, thereby sub-chi and female chi can be folded.

For sub-chi can be slided along female chi, on female chi, be provided with the chute parallel with the scale edge, rotating shaft is stuck in the chute.

For the ease of drawing circular arc, on sub-chi, be furnished with the circular hole that can insert drawing pen at interval.

For sub-chi is overlaped with female chi better, on female chi, be provided with the chi groove that adapts with sub-chi profile, chute is located in the chi groove, and rotating shaft is made as the drawing and pulling type rotating shaft.When using, mention rotating shaft, drive sub-chi and break away from the chi groove, become two hinged rulers; When time spent not, it is parallel with female chi to rotate sub-chi, makes sub-chi fall into the chi groove by lower rotary shaft, so just can the folding drilling depth groove of bundle chi in.

In order to realize the compasses function, on sub-chi, be provided with angle index, the center of circle of angle index is located at the rotating shaft center.

The utility model has the advantages that: during use, sub-chi and female chi are separated, both can draw generic linear, can also draw many parallel lines by rotating shaft.When needs picture circular arc, the picture penholder in sub-chi circular hole, is driven sub-chi with pen and rotates the circular arc that draws.When the needs angulation, will treat that the center of circle of the angle measurement heart with sub-chi upper angle scale overlaps, treat that a limit of angle measurement overlaps with the straight line at 0 degree place, angle, treat that the angle index of another correspondence of angle measurement is angle to be measured.When time spent not, to rotate sub-chi and sub-chi is stuck in the chi groove be integrated, so just two rulers be folded into one ruler, this moment, drawing rule can work as common ruler use, and easy to carry.

Description of drawings

Fig. 1 is the user mode schematic diagram of the utility model embodiment;

Fig. 2 is the folded state schematic diagram of the utility model embodiment.

Among the figure: the female chi of 1-, 2-chi groove, 3-chute, 4-chi, 5-circular hole, 6-rotating shaft, 7-angle index, 8-0 degree scale, 9-0 degree scale.

The specific embodiment

As depicted in figs. 1 and 2, the utility model comprises female chi 1 and sub-chi 4, and sub-chi 4 is hinged on female chi 1 by rotating shaft 6, thereby sub-chi 4 and female chi 1 can be folded.On female chi 1, be provided with the chute parallel 3, can slide along chute 3 therein for rotating shaft 6 with the scale edge.When the circular hole 5 that a diameter 0.7mm is just arranged on the sub-chi 4 at a certain distance, sub-chi 4 rotate along rotating shaft 6, pencil is inserted in the circular hole 5, can draw the circular arc of certain radius, this moment, drawing rule can be used as compasses or divider use.

For sub-chi 4 is overlaped with female chi 1 better, on female chi 1, be provided with the chi groove 2 that adapts with sub-chi 4 profiles, chute 3 is located in the chi groove 2, and rotating shaft 6 is made as the drawing and pulling type rotating shaft.When using, mention rotating shaft 6, drive sub-chi 4 and break away from chi groove 2, become two hinged rulers; When time spent not, it is parallel with female chi 1 to rotate sub-chi 4, makes sub-chi 4 fall into chi groove 2 by lower rotary shaft 6, sees that sub-chi 4 is folded into a ruler with female chi 1 on so from the side.

It can also be seen that from figure be provided with angle index 7 on sub-chi 4, the center of circle of angle index 7 is located at rotating shaft 6 centers, angle is to be decided to be 0 degree scale 8 among the embodiment perpendicular to sub-chi 4 directions, and angle value increases progressively clockwise, and the angle codomain is 90 degree.When the needs angulation, earlier sub-chi and female chi are adjusted to mutual plumbness, to treat that the center of circle of the angle measurement heart with sub-chi upper angle scale overlaps, top that limit for the treatment of angle measurement overlaps with female chi, the stator chi, clockwise rotate female chi, corresponding angle index is angle to be measured when female chi forwards to another coincidence for the treatment of angle measurement.

Angle also can be decided to be 0 degree scale 9 to be parallel to sub-chi 4 directions among the embodiment, and angle value increases progressively counterclockwise, and the angle codomain is 90 degree.When the needs angulation, earlier sub-chi 4 is adjusted to vertical coincidence status with female chi 1, to treat that the center of circle of the angle measurement heart with sub-chi upper angle scale overlaps, top that limit for the treatment of angle measurement overlaps with female chi, fixing female chi, clockwise rotate sub-chi, corresponding angle index was angle to be measured when the group chi forwarded to another coincidence for the treatment of angle measurement.
