Description

A kind of measuring instrument

Technical field

A kind of measuring instrument relates to field of measuring technique.

Background technology

In actual measurement, be mostly the length measuring instrument of photoelectricity class, such as escape canal, ramp detour.But laser measurement can only measure 2 between distance, be difficult to measure the length of arbitrary curve.All the other box chis, tape measure limited length, and the restriction that stretched by tape measure for length of a curve while measuring, also be difficult to the length of Measurement accuracy arbitrary curve.Be not easy to field operation.A kind of measuring instrument prior art of roller type such as Chinese patent CN202420437U are three-wheel slip vehicle, install numerous and diverse bulky equal inconvenience that portably uses.

Summary of the invention

For the deficiency that prior art exists, such as mostly irrigation canals and ditches when measuring the plumbing irrigation canals and ditches are to build on the spot, be crooked, usually need to calculate the once pressure loss of length of necessarily flowing through, with tape measure, tape measure or photoelectric measurement, what measure is all distances of point-to-point transmission, and in-site measurement is very inconvenient.The application's purpose is to provide a kind of volume little, lightweight, portable a kind of measuring instrument.A kind of measuring instrument adopts following technical scheme for achieving the above object:

1, a kind of measuring instrument, comprise long-armed handle 1, long pivot arm 2, range finding dish 3, index dial 4, pointer cover 5, dome screw 6, pointer 7, short pivot arm 8, turning axle 9, packing ring 10, length pivot arm supporting traverse 11; It is characterized in that: long pivot arm 2 is connected with short pivot arm 8 by length pivot arm supporting traverse 11, and long pivot arm 2 is connected and is " h " shape with length pivot arm supporting traverse 11, short pivot arm 8; Range finding dish 3 is the oblate cylinder of two sides indent, and range finding dish 3 is " work " font by the center of circle with the disk vertical cross-section, on a side outer rim of range finding dish 3, index dial 4 is arranged; Long pivot arm 2, range finding dish 3 centers are equipped with the turning axle 9 vertical with range finding dish 3 discs; Turning axle 9 one ends are fixed in long pivot arm 2 by packing ring 10, dome screw 6, and turning axle 9 other end encapsulations have pointer cover 5, and are fixed on short pivot arm 8 by packing ring 10, dome screw 6; Turning axle 9 is fixed between long pivot arm 2 and short pivot arm 8; Pointer 7 one end concatenation pointer covers 5; Described range finding dish 3 is wear-resisting hard rubber-plastics material.

2, described a kind of measuring instrument is characterized in that: described long pivot arm 2 is parallel to each other with short pivot arm 8.

3, described a kind of measuring instrument is characterized in that: described long-armed handle 1 connects long pivot arm 2.

4, described a kind of measuring instrument is characterized in that: described long pivot arm 2 is orthogonal with length pivot arm supporting traverse 11.

5, described a kind of measuring instrument is characterized in that: described short pivot arm 8 is orthogonal with length pivot arm supporting traverse 11.

6, described a kind of measuring instrument, is characterized in that: the girth=1m of described range finding dish 3.

7, described a kind of measuring instrument, is characterized in that: the scale division value=1cm of described index dial 4.

8, described a kind of measuring instrument is characterized in that: described long pivot arm 2, short pivot arm 8, length pivot arm supporting traverse 11 are rubber-plastics material.

9, described a kind of measuring instrument is characterized in that: described long pivot arm 2, short pivot arm 8, length pivot arm supporting traverse 11 are hollow square tube.

The accompanying drawing explanation

Fig. 1: a kind of measuring instrument front view;

Fig. 2: a kind of measuring instrument left view;

Fig. 3: a kind of measuring instrument partial enlarged view.

In figure: 1 long-armed handle, 2 long pivot arms, 3 range finding dishes, 4 index dials, 5 pointer covers, 6 dome screws, 7 pointers, 8 short pivot arms, 9 turning axles, 10 packing rings, 11 length pivot arm supporting traverses.

Beneficial effect

1, a kind of measuring instrument is simple in structure easy to use;

2, a kind of measuring instrument cost of manufacture is cheap;

3, a kind of measuring instrument is lightweight easy to carry;

4, a kind of measuring instrument, scale division value=1cm measuring accuracy is higher;

5, increase the pointer indication, measuring accuracy is high;

6, range finding dish 3 has lightweight durable characteristics for wear-resisting hard rubber-plastics material;

7, because long pivot arm 2 is connected and is " h " shape with length pivot arm supporting traverse 11, short pivot arm 8, turning axle 9 is fixed between long pivot arm 2 and short pivot arm 8, and during measurement, the range finding dish keeps vertical with tested surface of contact, can not roll.

8, range finding dish 3 is wear-resisting hard rubber-plastics material, because being worn when rugged or the ground survey of sandstone head, does not affect measuring accuracy;

9, range finding dish 3 is the oblate cylinder of two sides indent, and range finding dish 3 is " work " font, the effect that has weight reduction and gain in strength by the center of circle with the disk vertical cross-section.

Embodiment

1, a kind of measuring instrument, comprise long-armed handle 1, long pivot arm 2, range finding dish 3, index dial 4, pointer cover 5, dome screw 6, pointer 7, short pivot arm 8, turning axle 9, packing ring 10, length pivot arm supporting traverse 11; It is characterized in that: long pivot arm 2 is connected with short pivot arm 8 by length pivot arm supporting traverse 11, and long pivot arm 2 is connected and is " h " shape with length pivot arm supporting traverse 11, short pivot arm 8; Range finding dish 3 is the oblate cylinder of two sides indent, and range finding dish 3 is " work " font by the center of circle with the disk vertical cross-section, on a side outer rim of range finding dish 3, index dial 4 is arranged; Long pivot arm 2, range finding dish 3 centers are equipped with the turning axle 9 vertical with range finding dish 3 discs; Turning axle 9 one ends are fixed in long pivot arm 2 by packing ring 10, dome screw 6, and turning axle 9 other end encapsulations have pointer cover 5, and are fixed on short pivot arm 8 by packing ring 10, dome screw 6; Pointer 7 one end concatenation pointer covers 5; Described range finding dish 3 is wear-resisting hard rubber-plastics material.

The technical scheme of putting down in writing except instructions, all the other are and well known to a person skilled in the art and repeat no more general knowledge.
