Description

Multifunctional ruler

Technical Field

The utility model relates to a ruler especially relates to a multifunctional ruler.

Background

The ruler is one of the necessary learning tools for students, at present, various rulers sold on the market are various, and in order to realize folding and rotation of the ruler, a plurality of rulers are fixed by nails or bolts, so that the fixing is very insecure, and connecting shafts at two ends of the ruler are very easy to slide and fall off, so that the ruler is very inconvenient; in addition, many students often use the eraser to draw pictures, and when the students feel hot in summer and have sweats after writing for a long time, the students can easily get the written fringed and dirty; which is not beautiful; moreover, in the drawing process, other colors are often used for marking problems, and if a colored fountain pen is not available, carbonless colored carbon paper can be used for replacing the colored carbon paper, but the carbon paper is thin and is not easy to carry, and the like.

Two utility models with publication numbers CN02244242.1 and 200720084032.X disclose a multifunctional ruler, it all comprises ruler 1, ruler 2 and spike, and characterized by that the ruler face hole position of ruler 1 is connected in the ruler face hole position of ruler 2 with the spike, also can realize drawing some angles and figures commonly used like this, and measure the length of adjacent both sides, nevertheless control two rulers with the spike, do not have stability, the phenomenon of the smooth silk still appears easily, durable for a long time.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a multifunctional ruler with a position-limiting post and a positioning groove, which can be attached with a small brush and inserted with carbonless color copy paper.

In order to solve the technical problem, the utility model provides a take multi-functional ruler of spacing post and constant head tank, its characterized in that: including first ruler, second ruler, rotate the locking cap of being connected with the upper end of first ruler and the left end of second ruler, all evenly be equipped with the scale along the extending direction on first ruler and the second ruler, fixedly connected with angle scale's one end on the second ruler has spacing post on the first ruler, and spacing capital portion has spacing cap, and spacing post is by threaded connection with spacing cap, and angle scale is the arc and is equipped with the scale along the arc direction, and the centre of angle scale is equipped with the constant head tank along the arc extending direction, and spacing post is located the constant head tank, and the bottom of first ruler is provided with little brush, and the bottom of second ruler is provided with the inner chamber that can insert the copy paper.

Furthermore, the limiting column and the positioning groove can be connected in a sliding mode.

Furthermore, the limiting column is connected with the limiting cap through threads.

Furthermore, the cross section of spacing cap is greater than the cross section of constant head tank, prevents that the drop phenomenon from appearing in the constant head tank.

Furthermore, the small hairbrush can be transversely placed in the transverse groove at the bottom end of the first ruler.

Furthermore, the bottom end of the second ruler is provided with an interval inner cavity, so that the color carbonless copy paper can be conveniently inserted.

Furthermore, the back of the second ruler, which is inserted into the copy paper, is provided with an upper opening and a lower opening, and the opening is provided with a rear cover, so that the second ruler can be conveniently covered when not in use.

Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model provides a can be through locking cap, a take multi-functional ruler of spacing post and constant head tank, this ruler not only can realize the ruler that uses commonly and rule measurement function, also can draw some angles commonly used through the rotation angle chi, and can measure the length on two limits, in the use, utilize triangle-shaped's stability, under the control of arc constant head tank, ensure that the ruler is more firm, be difficult for the slippage, from taking little brush simultaneously, can sweep away the vestige under the eraser, can also insert colored carbonless copy paper, mark notes of different colours etc..
