Abstract
The utility model relates to a measuring ruler, in particular to a ruler for measuring boar height. The ruler mainly solves the problem that the boar height can not be measured exactly. The ruler comprises a ruler body with graduations; the top part at one end of the ruler body is fixed with a transverse ruler; a sliding ruler is arranged on the straight ruler; a through hole is arranged at one end of the sliding ruler; the sliding ruler is sheathed on the ruler body by the through hole; the transverse ruler and the sliding ruler are vertical to the ruler body and are arranged in parallel with one another; a right-angle plate is fixed on the sliding ruler; a right-angled edge of the right-angle plate is fixed below the sliding ruler; and the other right-angled edge of the right-angle plate is clung to the external side of the ruler body. By adjusting the sliding ruler, the scales at the back part of the boar can be measured exactly, thus avoiding the error owning to the observation by naked eyes; and the ruler can be operated simply, practically and conveniently.
Description
Technical field
This utility model relates to a kind of gage, specifically a kind of boar height dip stick.
Background technology
Seed selection is the key link in the breeding work, and correct seed selection will be based on the accurate evaluation of poultry heredodiathesis.At present, the conventional selection-breeding of main dependence in the breeding of pig, promptly by individual performance measurement, performance measurement born of the same parents and descendant's performance measurement, adopt advanced BLUP method (best linear unbiased estimation method) that reproductive performance, growth promoter and the finishing ability etc. of pig are carried out genetic evaluation, according to assessment result and the build macroscopic features replacement gilt of selecting and remain, carry out the subculture selection-breeding.Therefore, the boar performance measurement is important link and work in the pig breeding, and the accuracy of determination data directly influences the genetic improvement process of pig.Growth promoter is measured body chi index determinings such as comprising body weight and height, body length, chest measurement, abdominal circumference, lower limb hip circumference in the performance measurement character of pig, and wherein the mensuration of boar height requires to use hard chi to measure, and promptly uses the vertical dimension of hard chi mensuration pig hair worn in a bun or coil first to ground.
Use the cane chi to measure the vertical dimension of pig hair worn in a bun or coil first peak to the mensuration of boar height at present, main scale is stood vertically near the carcass left fore, again the upper end crossfoot is lain against the peak of hair worn in a bun or coil first, can read the height on the main scale to ground.This assay method need measured the straight stance of pig maintenance nature, not askew partially, the upward act, not sagging of head, lower jaw and breast abdomen are put in crossfoot the peak of hair worn in a bun or coil first fast in the time of should be basically on a horizontal line, need to make crossfoot and main scale to meet at right angles simultaneously, but measuring pig in practical measurement keeps the time of the straight stance of nature to be difficult for assurance, need the long time when often measuring, and be that crossfoot and main scale keep the right angle to have subjective consciousness and deviation in this method.
The utility model content
The purpose of this utility model is to provide a kind of boar height dip stick, solves the boar height and measures time-consuming, inaccurate problem.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of boar height dip stick, comprise and be with graduated ruler body, it is characterized in that, one end top of described ruler body is fixed with a balance chi, also be provided with a crossfoot on the ruler body, one end of crossfoot is provided with through hole, and crossfoot is placed on the ruler body by through hole; Described balance chi is all vertical with the ruler body with crossfoot, and is parallel to each other; Described crossfoot one end is fixed with a L-square, and a right-angle side of L-square is fixed on the crossfoot below, and another right-angle side fits in the ruler body outside.
The beneficial effects of the utility model are: can prevent that by increasing the balance chi crossfoot from skidding off, when measuring height, also make things convenient for grasping, but regulate the height of crossfoot rapid and accurate determination pig, and simple to operate practical and convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 ruler body, 2 balance chis, 3 crossfoots, 4 L-squares
The specific embodiment
As shown in Figure 1, a kind of boar height dip stick comprises and is with graduated ruler body 1, one end top of described ruler body 1 is fixed with a balance chi 2, also be provided with a crossfoot 3 on the ruler body 1, an end of weighing apparatus chi 3 is provided with through hole, and crossfoot 3 is placed on the ruler body 1 by through hole; Described balance chi 2 is all vertical with ruler body 1 with crossfoot 3, and is parallel to each other, and balance chi 2 can prevent that also crossfoot 3 from skidding off ruler body 1; Also be fixed with a L-square 4 on the described crossfoot 3, a right-angle side of L-square 4 is fixed on crossfoot 3 belows, and another right-angle side fits in ruler body 1 outside, can guarantee the perpendicularity of crossfoot 3 and ruler body 1 like this, makes to measure to save time, accurately.
Can make ruler body 1 vertically place ground when measuring height, hand-held balance chi 2, mobile crossfoot 3, laterally perpendicular to the hair worn in a bun or coil first place of pig to be determined, accurate reading rapidly then, perfect aspect high assay, not only guaranteed the accuracy of determination data, and measured rapidly, saved time.
