Abstract

The utility model relates to a multi-purpose gauge which can draw circles, ellipses, any angles and straight lines and can visually measure angles. The multi-purpose gauge comprises a gauge frame body and gauge feet, wherein, the gauge frame body comprises two gauge legs [1] and a semicircular protractor [2] which are connected through a movable screw [3], and the semicircular protractor [2] is clamped between the two gauge legs [1]. The lower parts of the compass legs [1] are provided with retaining nuts [5] which are connected with compass feet or ellipsograph feet. The upper parts of the gauge legs [1] are provided with indication lines or pointers [4] which indicate angles. The utility model has the advantages of simple structure, convenient operation, a plurality of functions and low cost.

Description

Multi-purpose compass

The utility model belongs to stationery.

Existing compasses and ellipsograph all only have single picture circle or oval function, owing to often run into the problem at angulation and any angle of drafting in drawing, therefore the special implement that needs other causes drafting instrument quantity to increase, and a lot of people of making of drafting instrument feel vexed very.

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, can draw circles and ellipse, and energy angular and draw any angle can replace the multigauge of ruler simultaneously again again.

Main points of the present utility model are to connect two rules and regulations legs and a semicircle protractor with a movable screw, the clamp nut that connects existing compass foot or ellipsograph pin is equipped with in two rules and regulations leg bottoms, and two rules and regulations legs indicated angle on protractor is the angle of two rules and regulations legs.

Description of drawings:

Fig. 1 is the multigauge schematic diagram.

Below in conjunction with accompanying drawing the utility model is done detailed description:

The utility model is made up of rule frame body and rule pin two parts, and the rule pin comprises existing compass foot and two kinds of patterns of ellipsograph pin, and they can be pencil or writing brush formula.The rule frame body is made up of two rules and regulations legs (1) and a semicircle protractor (2), rule legs (1) are connected by the circle centre position of a movable screw (3) at semicircle protractor (2) with semicircle protractor (2), semicircle protractor (2) is clipped between the two rules and regulations legs (1), can make the free activity of two rules and regulations legs (1) or be fastened on needed position by the degree of tightness of adjusting movable screw (3).Semicircle protractor (2) is gone up the angle index trace can that is: 1. press protractor 0～180 ° of mark from left to right by the dual mode mark; Or 2. usefulness protractor center line with protractor in two, from center line top vector hornwork two ends respectively by 0～90 ° of mark.The length mark that extends downwards from semicircle protractor (2) circle centre position is all arranged on the two rules and regulations legs (1), and the markings or the pointer (4) of indication angle arranged at rule leg (1) top, and there is the clamp nut (5) that connects the rule pin rule leg (1) lower end.Like this, two rules and regulations legs (1) are gone up indicated angle (designation data sum or poor) at semicircle protractor (2) and are folded angle between two rules and regulations legs/(1), utilize this angle can make any angle of 0～180 °, when two rules and regulations legs (1) rotated on the straight line, multigauge can be made ruler and use.Semicircle protractor (2) can be used for angulation on the one hand, plays the effect of hand-held screw rod simultaneously again.Under two rules and regulations legs (1), mix existing compass foot or ellipsograph pin, then can draw circle or oval.

The utility model is simple in structure, easy to use, cost is low, simultaneously again can draw circles, ellipse, random angle, straight line, and can be used for angulation, have widely practical value.

Claims

1, a kind of multigauge, form by rule frame body and rule pin, the rule pin comprises two types on compass foot and ellipsograph pin, the rule frame body that is characterised in that of the present utility model is made up of two rules and regulations legs/[1] and semicircle protractor [2], semicircle protractor [2] is sandwiched between the two rules and regulations legs [1], and rule legs [1] are connected by movable screw [3] with protractor [2].

2, multigauge as claimed in claim 1, the angle indentation that it is characterized in that described semicircle protractor (2) is by 0～180 ° of mark from left to right, or by semicircle protractor (1) center line in two, respectively press 10～90 ° of marks from the center line top to two ends with it.

3, multigauge as claimed in claim 1, it is characterized in that all having on the two rules and regulations legs (1) from the long measure indentation of semicircle protractor (2) circle centre position to the bottom continuity, the index line or the pointer (4) of an indication angle respectively arranged at rule leg (1) top, and a clamp nut (5) that connects the rule pin is respectively arranged at rule leg (1) bottom.
