Abstract

The utility model provides a clinometer. A rectangular main board is marked with a half angle measuring disk, and two ends of a bottom line of the angle measuring disk are respectively fixed with two aiming pins. The center namely the circular center of the bottom line is drilled with a hole, the other corresponding half part of the angle measuring disk is drilled with a fixing hole, and thin thread bound with a heavy hammer and marked with scales of an end head is wound on a thread wheek and fixed in the fixing hole. The utility model has the advantages of small size, convenience for carrying, convenient operation and exact data measurement.

Description

A kind of dip meter

It is the instrument of the measuring angle of feature to adopt mechanical means that the utility model relates to a kind of, especially a kind of dip meter.

In life, people often need to measure the number of degrees at a certain target elevation angle, pitch angle, so that carry out correlation computations.So just need to measure the instrument at angle of inclination, and at present, mostly adopt the huger ruler of volume, bevel protractor to form, carry very inconvenient.

The purpose of this utility model provides that a kind of measurement data is accurate, and volume is little, portable dip meter.

The utility model has adopted following technical scheme to realize: be carved with the angulation scale on rectangular mainboard half, fix two aiming nails respectively at the bottom line two ends of angle scale, the bottom line center is circle centre position boring, second half brill in the angle scale correspondence installs and fixes the hole, and the graduated fine rule that a weight is tied up in the termination is gone up and is fixed on around the line wheel through the center of circle and installs and fixes on the hole.

The utility model volume is little, is easy to carry, and is easy to use and measurement data is accurate.

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model user mode synoptic diagram.

Shown in the figure: 1, mainboard 2, angle scale 3, aiming nail 4, bottom line 5, fine rule 6, circle center hole 7, fixed orifice 8, line wheel 9, weight

The utility model is to be carved with half angulation scale (2) on rectangular mainboard (1), fix two aiming nails (3) respectively at bottom line (4) two ends of angle scale (2), the bottom line center is circle centre position boring (6), second half brill in the angle scale correspondence installs and fixes hole (7), and the graduated fine rule (5) that a weight (9) is tied up in the termination is gone up and is fixed on around line wheel (8) through the center of circle (4) and installs and fixes on the hole (7).Line wheel, fine rule, weight have just been formed a device that can replace the ruler in traditional dip meter of being convenient to folding and unfolding, this device is installed in hole (7) to be located, and require can rotational line wheel (8) and retractable cable (5) so just can utilize this fine rule to point out the angle of inclination of the object of surveying easily.

In use, observing eye (10) drops on the same straight line with two aiming nails and tested point (11), according to the geometrical principle that equates with the complementary angle at angle as can be known, the inclination angle ∠ α that surveys equals the angle number of the angle ∠ β of weight line and zero degree line, and the weight line is discarded to the height that the length of centre point is dip meter.

Claims

1. dip meter, comprise bevel protractor, it is characterized in that being carved with on the rectangular mainboard (1) half angulation scale (2), fix two aiming nails (3) respectively at bottom line (4) two ends of angle scale (2), the bottom line center is circle centre position boring (6), second half brill in the angle scale correspondence installs and fixes hole (7), and the graduated fine rule (5) that a weight (9) is tied up in the termination is gone up and is fixed on around line wheel (8) through the center of circle (4) and installs and fixes on the hole (7).
