Abstract

The utility model relates to a multi-functional movable ruler which belongs to the class of the stationer goods. The utility model makes use of a plurality of straight rulers which are in same sizes and are not provided with redundant sides. The middle part of each straight ruler is provided with a groove, and the both ends of each straight ruler are separately provided with a round hole. A moveable or fixed moving button which combines two rulers is arranged in each groove. The design with multiple functions can be finished according to different requirements in operating. The multi-functional movable ruler can be used for multiple functions of an expansion ruler, a movable angle square, a compass (the radius can be simultaneously displayed), a parallel ruler, a T-squares, an angle measurement, etc. The utility model has the advantages of convenient operation, and low cost.

Description

Multi-functional moveable scale

The utility model relates to a kind of multifunctional adjustable rule, belongs to stationery category.

The ruler purposes of using is single at present, will select multiple instrument for use if want to solve multiple use, and is very inconvenient.

The utility model utilizes the ruler on several pieces big or small identical nothing left limits, one groove is respectively arranged in the middle of the ruler, respectively there is a circular hole at two ends, there is one to be used in the groove in conjunction with the removable or fixing mobile button of two chis, can be during operation according to different needs, finish the design of multiple function, this adjustable rule can be used as Expansion ruler, adjustable angle square, compasses, parallel rule, T-square, multiple uses such as angular surveying, easy to use, low price.

Structure of the present utility model can be referring to accompanying drawing 1, its thematic structure comprises several pieces rulers (1) on folded nothing left limit mutually, one groove (2) is respectively arranged in the ruler, strip hole (2 ') is wherein arranged, move button (3) in the groove (2), mobile button major function is as the effect of screw, moves or fixing in conjunction with two chis, central point index line (4) is arranged on the mobile button (3), can be used for during operation proofreading and correct and the indication central point.The utility model itself is a ruler, its two sides has length scale (6) and angle index (7), draw back flexible function about two chi phase poststacks, need only loosen mobile button (3) during use, selected effect or move to suitable length or angle can freely be set, fixed after proofreading and correct aligning, just can be used.As L-shaped then be multidirectional adjustable angle square, as shown in Figure 2.Respectively there is a circular hole (5) at the two ends of two chis, can work as compasses uses, need only will draw back about two chis during use to required radius, also display size scale simultaneously when drawing back, selected after with the fixing circular hole of mobile button (3) with two ends, an end circular hole be spool, other end circular hole is drawn camber line, because two chis are the design of nothing left limit, the scale indication is arranged on the mobile in addition button, make it when operation, to be beneficial to proofread and correct to avoid.When drawing parallel lines or working as T square and use, then can fix a chi, 90 ° were moved about another chi was done, at this moment fixed ruler and the scale of attachable mechanical stage own, but whether mobile button index line all mutual correction tilts, and more than is positive the use.When as angular surveying and drawing, then use reverse side, following chi is the plane, mobile button is a central point, another chi that tilts moves the button index line indicate angle index thereupon in groove, reverse side then shows length conversely, for example wants 60 ° and 120 ° rhombuses that the diagonal angle is equilateral of standardized rhombus, configures size and angle, two actions can be finished, shown in (8) in the accompanying drawing 1.

Accompanying drawing 3 is some practical example of multifunctional adjustable rule, and for everybody reference, as seen its purposes extensively reaches conveniently.

Claims

1, a kind of multifunctional adjustable rule, it is characterized in that: its agent structure comprises several pieces rulers (1) on folded nothing left limit mutually, one groove (2) is respectively arranged in the ruler, one strip hole (2 ') is wherein arranged, have in the groove (2) one in conjunction with two chis removable or mobile button fixedly usefulness (3), respectively there is a circular hole (5) at the ruler two ends.
