Description
Technical field
This utility model belongs to technical field of measuring equipment, is specifically related to a kind of arc body chi measuring instrument.
Background technology
In the production practices and scientific research of animal feeding, using special measuring tool to measure each position of animal, is a kind of means of research appearance, estimation body chi and production capacity, is the important method that Modern Animal Husbandry is produced.Grasping body measurement technology is exactly the indispensable ABC of Animal husbandry production and basic skill, due to the different requirements that indices measures, the mensuration completing whole body chi needs the various uses chi comprising ruler, tape measure etc., in production practices, comparatively inconvenient owing to carrying multiple dip stick simultaneously, result in the loaded down with trivial details of operation, inevitably cause the error of measurement.
General measure animal body chi project mainly contains: body weight, height, body length, Body steep length, chest measurement, chest breadth, chest depth, recommend wide, more than ten project such as buttocks is wide, hip width, hip cross are high, circumference of cannon bone, body weight scale can complete, height, body length, chest measurement, hip cross are high, circumference of cannon bone etc. can have been come with tape, but chest breadth, chest depth, recommend wide, the multinomial measurement with radian such as buttocks is wide, hip width, generally use biltmore stick, tape is measured inaccurate, but biltmore stick comparatively speaking neither be very accurate.
Utility model content
For solving the above-mentioned technical problem existed in prior art, this utility model provides a kind of simple and reasonable, can measure the arc body chi measuring instrument of animal body arc part.
The purpose of this utility model is achieved through the following technical solutions:
A kind of arc body chi measuring instrument, comprise the first chi foot and the second chi foot, described chi foot is straight arc chi foot, comprise ruler and arc chi, described first chi foot and described second chi foot hinged at ruler end, also comprise data ruler, described data ruler is arranged on described first chi foot.
Wherein, described arc chi two ends straight length is described ruler length integer times.
Wherein, described arc chi two ends straight length is the integral multiple more than twice of described ruler length or twice.
Wherein, described data ruler is arranged on the first chi foot ruler and arc chi junction.
Wherein, described data ruler is at one end hinged with described first chi foot.
Wherein, described first chi foot and the second chi foot junction are spherical.
Wherein, described first chi foot is connected by screw with described second chi foot.
Wherein, described first chi foot is identical with described second chi leg structure, is mutually symmetrical.
Wherein, described arc chi end is spherical, prevents from damaging measured body.
Wherein, described data ruler is the ruler indicating numerical scale.
Wherein, described arc chi end and ruler are on the same line.
Concrete, the principle that this utility model utilizes is isosceles triangle and similar triangle theory, large isosceles triangle both sides are formed by two chi feet, utilize the arc chi bottom line of two chi feet as isosceles triangle base two-end-point, measure physical location size, be positioned on the position parallel with large isosceles triangle base by data ruler is arranged on, make the first chi foot ruler, second chi foot ruler forms the little isosceles triangle similar to large isosceles triangle to data ruler, the number of degrees on data ruler are little isosceles triangle base length, and then according to Similar Principle of Triangle, large isosceles triangle base length can be calculated, namely the length of the physical location measured is needed.
Wherein, described arc body chi measuring instrument can be set to closure state in non-measured state, first chi foot is overlapped with the second chi foot ruler section, simultaneously, because data ruler and the first chi foot are hinged, therefore, in non-measured state, data ruler can be arranged and be that the first chi foot and the second chi foot ruler are gone up in line, reduce placement space.In use, data ruler is gone to the straight line formed with two arc chi ends and be in parallel position.
Wherein, the first chi foot, the second chi foot and data ruler are all made of metal, moisture resistance, not yielding, measurement data is accurate.
Disclosed in this utility model, arc body chi measuring instrument can carry out body measurement to many animals, as pig, sheep, cattle, deer etc.
The beneficial effects of the utility model are:
Arc body chi measuring instrument disclosed in the utility model, easy to carry, simple to operate, and the accuracy of every determination data can be ensured, efficiently solve in production process and in every Body size measurements, carry inconvenience, measure the drawbacks such as inaccurate.
Accompanying drawing explanation
Fig. 1 is structural representation under a kind of arc body chi of this utility model measuring instrument using state;
Fig. 2 is structural representation under a kind of arc body chi of this utility model measuring instrument non-working condition;
Wherein, 1-first chi foot, 2-second chi foot, 3-ruler end, 4-arc chi end, 5-data ruler, 6-data ruler connecting portion, 7-fixed screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of sheep arc body chi measuring instrument, comprise the first chi foot 1 and the second chi foot 2, described first chi foot 1 is that two structures are identical with the second chi foot 2, straight arc chi foot mirror one another, comprise ruler and arc chi, described arc chi two ends straight length is 2 times of described ruler length, and described arc chi end and ruler are on the same line.Described first chi foot 1 is hinged by fixed screw 7 at ruler end 3 with described second chi foot 2, and described first chi foot 1 and the second chi foot 2 junction are spherical.The arc chi end 4 of described first chi foot and the second chi foot is also all set to spherical, prevents from damaging sheep body.Measuring instrument also comprises the data ruler 5 that can have numerical scale, and described data ruler 5 is arranged on the junction of described first chi foot 1 ruler and arc chi.Described ruler end 3 is 1/3 of the spacing of whole chi foot two-end-point with the distance of data ruler connecting portion 6.Because sheep belongs to middle-size and small-size animal, the arc part rule of thumb measured can not more than 60cm, therefore in this example, within the length of data ruler 5 is arranged on 20cm.
As shown in Figure 2, described arc body chi measuring instrument can be set to closure state in non-measured state, first chi foot 1 is overlapped with the second chi foot 3 ruler, simultaneously, because data ruler 5 and the first chi foot 1 are hinged, therefore, in non-measured state, data ruler 4 can be arranged and be that the first chi foot 1 and the second chi foot 2 ruler are gone up in line, reduce placement space.In use, data ruler 5 is gone to the straight line formed with two arc chi ends 4 and be in parallel position.
Wherein, the first chi foot 1, second chi foot 2 is all made of metal with data ruler 4, and moisture resistance not yielding, measurement data is accurate.
Finally it should be noted that, the foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, although be described in detail this utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
