Abstract

A line measuring ruler is a straight scale. Contour lines of middle portions of the upper end and the lower end of the straight scale are parallel and straight. For convenience of narration, here, the contour lines are end lines. An upper end line and a lower end line are respectively arranged at the upper end and the lower end of the straight scale and are mutually parallel. Both the obverse side and the reverse side of the straight scale are provided with measurement scales between the upper end line and the lower end line, scales of one side of the straight scale comprise scales from the upper end line serving as the 0 point in measurement to the lower end line, and scales of the reverse side of the straight scale comprise scales from the lower end line serving as the 0 point in measurement to the upper end line. The line measuring ruler is suitable for measuring of soft rope-shaped articles or strip-shaped articles in markets.

Description

Amount rope chi

Technical field

The invention belongs to a kind of ruler of measuring length, particularly be fit to measure the ruler of tightrope length.

Background technology

Measure tightrope length with ruler, present method is every amount one chi, is pinching with hand and is just measuring the place of arriving, and measures a chi again, and such amount method is not too convenient.

Summary of the invention

Ruler is hard, and it is flexible that tightrope has, and when tightrope length during times over ruler length, measures just trouble, and the present invention has overcome shortcoming of the prior art, and a kind of ruler of suitable measurement tightrope is provided; Technical scheme of the present invention is:

A kind of amount line chi is a kind of ruler, and the described ruler up and down outline line of two ends center section all is straight, for sake of convenience, at this, this section outline line is called end line, described ruler has respectively upper end line and lower end line in two ends up and down, and described up and down two end lines are parallel to each other; It is 0 size scale that the front of described ruler indicates above end line, until lower end line, it is 0 size scale that the reverse side of described ruler indicates following end line, until upper end line.

The present invention can also be, it is 0 size scale that the front of described ruler indicates above end line simultaneously, until lower end line, and following end line is 0 size scale, until upper end line, the reverse side of described ruler has and positive same mark.

The present invention can also be four jiaos of parts with the protrusion extension of line of vector chi two ends of described amount line chi;

The invention has the beneficial effects as follows: measure once, do not need memory and calculate just can draw more accurately result, and also very clear, do not need to crosscheck, use very convenient.

This amount rope chi, as its name suggests, the suitable amount tightrope is fit to measure all ropy with certain flexibility and ribbons too.

Description of drawings

Fig. 1 is the synoptic diagram in a kind of amount rope chi front.

Embodiment

As shown in Figure 1, be that a kind of selection is the amount rope chi that wood chip or duroplasts etc. are made, getting up and down, the distance of end line is this specification of 50cm; This amount rope chi wherein scale of one side comprises that from upper end line be 0 scale that measures, and comprises that also from lower end line be 0 scale that measures simultaneously, until upper end line, two is vertical about these two kinds of scale marks were divided into; Four jiaos of this chi have part from extension to the ruler two ends that protrude, so that ruler two ends intermediate recess, the winding rope period of the day from 11 p.m. to 1 a.m, rope is difficult for slippage; The reverse side of this chi is the same with the front.

The using method of this amount rope chi is such: take the amount tightrope as example, 0 alignment of tightrope head and amount rope chi one end, pinch with a hand, another handgrip tightrope is around the a-circle-by-a-circle winding of up and down end line of this chi, rich in last, the number number is one meter long around several circles around a circle, be half meter around half-turn, remaining part is reading out data from the blade directly.

This amount rope chi is well suited for the shop-assistant and uses when selling ropy, because the result can check, makes the client convince, and avoids not measuring, and rope has been cut size wrong.

Claims

1. an amount line chi is a kind of ruler, and the described ruler up and down outline line of two ends center section all is straight, for sake of convenience, at this, this section outline line is called end line, described ruler has respectively upper end line and lower end line in two ends up and down, and described up and down two end lines are parallel to each other; It is characterized in that it is 0 size scale that the front of described ruler indicates above end line, until lower end line, it is 0 size scale that the reverse side of described ruler indicates following end line, until upper end line.

2. a kind of amount line chi according to claim 1 is characterized in that, it is 0 size scale that the front of described ruler indicates above end line simultaneously, until lower end line, with following end line be 0 size scale, until upper end line, the reverse side of described ruler has and positive same mark.

3. a kind of amount line chi according to claim 1 and 2 is characterized in that, four jiaos on described ruler has and protrudes the part of extending to the ruler two ends.
