Abstract

The utility model aims to provide a simple dipmeter, which can solve the measurement problem of space plane slant angles and tooling angles. The specific technical scheme includes: making use of a ready-made plastic product, i.e. a multi-purpose rectangular equilateral triangular ruler with a semicircular protractor in the center, drilling a small pin hole at the center of a semicircle with angle scales, passing a fine line through the pinhole, fixing one end of the fine line on the small pin hole, and tying a heavy object to the other end to form free hanging, thus forming the simple dipmeter. The working principle is that: according to the need of an angle to be measured, one side of the simple dipmeter (rectangular equilateral triangular ruler) is selected and leaned to a surface or object needing measurement, due to the action of gravity, the heavy object sags naturally, the fine line is straightened, the angle between the measured surface or object and the gravity direction can be read from the position of the fine line and the triangular ruler scale, and the accuracy is within 0.5 degree.

Description

A kind of simple and easy drift indicator

Technical field

The utility model relates to engineering surveying instrument, and a kind of simple and easy drift indicator is applied to the actual angle after the actual inclination angle of measurement space object in engineering or frock.

Background technology

In Practical Project, often run into some practical problemss to space plane pitch angle, frock measurement of angle, with checking construction or frock, whether reach designing requirement.For this class work, although existing various specialized equipments, but for non-recurrent work, or even disposable work cost fund goes to buy the specialized equipment waste that seems very, so a kind of drift indicator easy, that easily make seems extremely meaningful, both can meet request for utilization, save again cost, very practical.

Summary of the invention

The purpose of this utility model is to provide a kind of simple and easy drift indicator, can solve the problem to space plane pitch angle, frock measurement of angle.Concrete technical scheme is: utilize the centre of ready-made plastic products to contain the multiplex right angle equilateral triangle chi of semicircular protractor, bore a little pin hole in the semicircle center of circle that angle index is arranged, wear a fine rule in pin hole, one end of line is fixed on little pin hole, the other end is a weight, free suspension, so just carried out.

Its principle of work: the angle of measuring as required needs, select a limit of simple and easy drift indicator (right angle equilateral triangle chi) recline with measured of needs or object on, due to Action of Gravity Field, weight naturally droops, fine rule is straightened, can read the angle of measured or object and gravity direction from fine rule and set square angle index position, precision is in 0.5 degree.

Description of drawings

Fig. 2 is that of the present utility model another measured sketch.

1. testees in figure, 2. set square, 3. fine rule, 4. weight, 5. rectangular parallelepiped.

Embodiment

Below in conjunction with drawings and Examples, the present invention is described in further detail.

The comparison of simple and easy drift indicator is simple, prepares the right angle equilateral triangle chi 2 that contains semicircular protractor in a centre, a fine rule 3 and the weight 4 that volume is little.A little pin hole (aperture is more little more accurate) is bored in the center of circle at the semicircular protractor of right angle equilateral triangle chi, and fine rule is passed little pin hole, and an end of fine rule is beaten the one side that a fast knot is stuck in set square and fixed, and weight is hung as weight by other end system.So easy drift indicator has just been carried out.

The use of simple and easy drift indicator: the usage comparison of simple and easy drift indicator is convenient, and the angle of measuring is as required selected the limit of different set squares recline tested surface or object.

Embodiment 1: as shown in Figure 1, measure the top rake of testee 1, according to the needs that take measurement of an angle, the hypotenuse of choice for use set square 2 abuts in a side of testee 1, weight 4 naturally droops because of gravity, after weight was stable, according to fine rule 3 and the set square 2 direct readings in angle index position, whether checking frock angle met design requirement.Measuring error is less than 0.5 degree.

Embodiment 2: as shown in Figure 2, the pitch angle of testee 1, according to the needs that take measurement of an angle, one right-angle side of choice for use set square 2 abuts on testee 1 inclined-plane, because the free sagging space that needs of weight 4, so place a rectangular parallelepiped 5 as auxiliary cushion blocks on inclined-plane, weight 4 has had enough spaces to naturally droop like this, after weight was stable, according to fine rule 3 and the set square 2 direct readings in angle index position, whether the checking pitch angle met design requirement.Select the right-angle side testee inclined-plane that reclines to it should be noted that the conversion of angle, because during the right-angle side horizontal positioned of selecting, total indicator reading is 45 degree, so should be take 45 degree as 0 degree point.In Fig. 2 engineering survey is used, should deduct 45 degree in the angular readings on testee inclined-plane, be 75.5 degree as the measured value reading, the testee inclination angle of inclined plane should be 30.5 degree.Measuring error is less than 0.5 degree.

Claims (1)

1. simple and easy drift indicator, formed by set square (2), fine rule (3) and weight (4), it is characterized in that: the center of circle of the semicircular protractor of described set square (2) is drilled with a little pin hole, one end of fine rule (3) passes the little pin hole of set square (2) and is fixed on little pin hole, and there are a weight (4) and free suspension in the other end system of fine rule (3).
