Abstract

The utility model relates to a drawing tool. In the prior art, the functions of various drawing tools are single, and the use and the carrying are inconvenient. The drawing tool is that a movable ruler is connected with a fixed ruler by a connection component, and randomly rotates by taking the connecting piece as the axle center. One edge of the fixed ruler is a straight rule, and the other edge of the fixed ruler is a ruler whose middle part is provided with an angle meter. The corresponding angle can be drawn as long as the scale line or the indicated needle on the short edge of the movable ruler points to the desired angle on the angle meter of the fixed ruler and the cross edge of the fixed rule and the movable ruler is utilized. Therefore, the utility model provides a multi-purpose rule for drawing straight lines, and drawing and measuring angles.

Description

Multipurpose ruller

The utility model relates to a kind of drawing apparatus.In prior art, various drawing apparatus all are simple functions, use and carry equal inconvenience, and the cost height.

The purpose of this utility model is to provide a kind of multipurpose ruler, uses this multipurpose ruler can draw straight line, draws various angles, all right angulation, and use, easy to carry.

The utility model is achieved in that by a connector fixed ruler part and adjustable rule is partly linked together, forms a kind of multipurpose ruler.Two long limits of fixed ruler have function of use.One of them long limit is the ruler that has scale, in order to draw straight line.Another long limit is then formed by three sections, and middle one section is the protractor of half garden shape, and in order to measuring angle, and it is arbitrarily angled to cooperate adjustable rule to draw.0 degree point of protractor, 180 degree point and the garden heart are all on the center line of fixed ruler width.Other two sections respectively in the both sides of half garden shape protractor, for having the ruler of scale, can draw straight line.The heart place, garden of protractor is porose on the fixed ruler, so that connector is installed.Determine the form of connector according to the raw material situation of system chi.If with plastics and lucite, then the heart place, garden of protractor can be the column of giving prominence to, directly as connector.Two long limits and the minor face of adjustable rule on the multipurpose ruler have function of use.Two long limits are the ruler that has scale, in order to draw limit or other straight line of angle.A minor face mid portion of adjustable rule has pointer, and the summit of pointer is on the center line of minor face width.If system chi material can be transparent, then can be on this minor face without pointer, but be carved with graduation mark at the center line position of this minor face, in order to replace pointer.This graduation mark cooperate with protractor on the fixed ruler can draw required arbitrarily angled.Porose on the center line of adjustable rule width, the distance of the minor face of the central point in hole and band graduation mark is equal to or slightly less than the radius of protractor on the fixed ruler, this hole adjustable rule and fixed ruler are linked together, and adjustable rule can arbitrarily rotate in order to connector to be installed.Connector can take various forms according to the material difference of system chi, if the raw material of system chi adopt metal or timber, then connector can be used bolt, nut or rivet etc., if system chi raw material are plastics or lucite, then can press a sufficiently long column at heart place, the garden of fixed ruler protractor, make it pass hole on the adjustable rule, again this post is passed the part pressing of aperture, adjustable rule and fixed ruler are linked together, and adjustable rule can be that rotate arbitrarily in the axle center with the connector, so that draw required angle.

Advantage of the present utility model and good effect are the many usefulness of a chi, both can draw straight line, draw arbitrarily angled, can also measuring angle, and use, easy to carry, make simple, with low cost.

Below in conjunction with accompanying drawing specific embodiments of the present utility model is elaborated.

Fig. 1 is the fixed ruler of multipurpose ruler.

Fig. 2 is the adjustable rule of multipurpose ruler.

Fig. 3 is a multipurpose ruler.

Among Fig. 11 is the chi body of fixed ruler, and an one long limit is the ruler that has scale, and the mid portion on another long limit is the half garden shape protractor that is carved with 180 degree, and two are the ruler that has scale.2 is columns of plastics or lucite, its position in the garden of half garden shape protractor in the heart, this column is connector.If system chi raw material are metal or timber, then column changes the hole into, so that connectors such as construction bolt, nut or rivets.

3 is chi bodies of adjustable rule among Fig. 2, the 4th, and graduation mark, the 5th, in order to the hole of connector to be installed, the aperture is slightly larger than the external diameter of plastics on the fixed ruler or lucite column 2, so that form movingly between making 2,5.

Fig. 3 is enclosed within the hole on the adjustable rule 5 on the fixed ruler on plastics or the lucite column, and the part that again column 2 is passed adjustable rule flattens the multipurpose ruler that forms.Straight line all can be drawn in the long limit of fixed ruler on the multipurpose ruler and adjustable rule.Half garden shape protractor on the fixed ruler can measuring angle.Adjustable rule and fixed ruler cooperate then can draw required arbitrarily angled.As, draw 51 degree angles, then can be with protractor on the graduation mark secured in alignment chi on the adjustable rule 51 degree points, utilize two crossing limits of adjustable rule and fixed ruler just can draw again and relative 51 spend angles.

Claims

1, a kind of multipurpose ruler that is used to chart is made up of fixed ruler 1 and adjustable rule 3 and connector 2, it is characterized in that connector 2 is connected adjustable rule 3 on the fixed ruler, and adjustable rule 3 can be that arbitrarily rotate in the axle center with connector 2.

2, multipurpose ruler according to claim 1 is characterized in that a long limit of fixed ruler 1 is a ruler, and some is a protractor on another long limit.

3, multipurpose ruler according to claim 1 is characterized in that two long limits of adjustable rule 3 are ruler, and graduation mark or pointer 4 and hole 5 are arranged on the center line of a minor face.
