Abstract

A multi-purpose ruler comprises a stationary ruler of rectangular plate where scale is provided on the lateral edge and the cross edge, angle-measuring lines are engraved on the plate of the stationary ruler provided with a set pin, and a groove is made in a moving ruler plate with scale, which is mounted via the groove therein on the set pin. The new device has the advantages of a simple construction, easy use and multiple functions, and can be widely used as a tool for pupils, students of middle schools and technicians.

Description

Multipurpose ruler

The utility model relates to the chi with multiple function.

At present widely used chi with functions such as measuring straight line, angle is a kind of planar band orifice plate, and this chi does not have and fathoms exactly and the function of diameter, and people's slide calliper rule of having to be equipped with in addition in order to fathom so just bring multiple inconvenience to the user.

Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of simple in structure, cost is low, function is many, easy to use multipurpose ruler.

Task of the present utility model realizes as follows: it has a rectangular board-like scale multipurpose ruler, have scale on its side and the horizontal edge, be carved with the measuring angle line on the scale plate face, have groove on the scale plate, be equipped with steady pin on the groove, have groove on the moving chi plate face that has scale on it, moving chi is contained on the steady pin by the groove on it.

Therefore the utility model has the function of ruler and protractor owing to have plane scale and measuring angle line on the scale; Owing to be equipped with and its moving chi movingly on the scale, therefore can make things convenient for and measure diameter, the degree of depth exactly.

Fig. 1 is the utility model front view.

The best of the present utility model is executed example, as figure, it has a rectangular board-like scale 1 multipurpose ruler, have scale on its dual-side and the horizontal edge, be carved with the measuring angle line on the scale plate face, have groove on the scale plate, steady pin 2 is housed on the groove, have groove on the moving chi 3 plate faces, moving chi is contained on the steady pin 2 movingly by the groove on it.Can just can finish with scale when side amount straight line, measuring angle, measure and just can finish when needs fathom and promote moving chi during diameter, rotatable moving chi is directly finished when needs are drawn the oblique line of any angle.

Claims (1)

1, a kind of multipurpose ruler, it has a rectangular board-like scale, have scale on its side and the horizontal edge, be carved with the measuring angle line on the scale plate face, and have groove on the scale plate, it is characterized in that: be equipped with steady pin on the groove of scale plate, have groove on the moving chi plate face that has scale on it, moving chi is contained on the steady pin by the groove on it.
