Abstract
The utility model discloses a steel vernier measuring tape, belonging to measuring tools. The steel vernier tape is composed of an elastic component, a measuring tape housing, a measuring tape strip, a vernier sheet, and a measuring claw. The steel vernier measuring tape is characterized in that the vernier sheet is installed on the measuring tape strip, so that the vernier sheet can randomly move on the measuring tape strip; and both the measuring tape strip and the vernier sheet are equipped with uniform scales, so that the size of a large object can be accurately measured by comparing the two scales. The steel vernier measuring tape in which advantages of common steel measuring tapes and vernier calipers are combined can accurately measure large workpieces, solves the problem that the prior steel measuring tapes can not measure apertures and pitches, and can be widely applied to measurement of large workpieces in the machining field.
Description
Technical field
The utility model relates to a kind of measuring tape measure, especially a kind of cursor steel chi of energy precision measurement large-scale workpiece.
Background technology
At present, large-scale workpiece is machined in when measuring, because workpiece is larger, is difficult to accurate measurement.In common metering system, adopt tape measure, but the tape measure full accuracy only has 0.1cm, can not accomplish accuracy requirement, use higher vernier caliper on the measuring accuracy, but the measurement range of vernier caliper is limited, and dimension does not have in daily life a kind of not only simple but also can accurately measure the instrument of large-sized object.
Summary of the invention
In order to overcome the deficiency of above-mentioned tape measure and vernier caliper, the utility model provides a kind of novel cursor steel chi with vernier caliper and the combination of ordinary steel tape measure function.
The technical scheme in the invention for solving the technical problem is:
A kind of cursor steel chi is comprised of elastic parts, Flexible rule case, tape strip, vernier slice, measuring claw.It is characterized in that at tape strip a vernier slice being installed, vernier slice can be mobile arbitrarily on tape strip, at tape strip and vernier slice even scale arranged simultaneously, accurately measures the size of large-sized object by the comparison of two scales.
Equidistant scale is arranged on the described tape strip, minimum interval 0.1cm, per 10 spacings are 1cm, and corresponding Digital ID is arranged respectively.
The centre of described vernier slice is arc, and there is flanging at two ends, can be on tape strip slide arbitrarily, and width is arranged between tape strip is the gap of 0.005 cm.Even scale is arranged on the vernier slice, minimum spacing Lcm (wherein L is 0.98,0.95 or 0.9), vernier slice length is 5*L cm.
Described measuring claw is located at vernier slice end and tape strip front end, and measuring claw is cylindrical, and diameter 0.1 cm highly is 1 cm.
The beneficial effects of the utility model are:
The utility model can be measured large-sized object with the function combination of tape measure and vernier caliper, can accomplish accurate measurement again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation.
Fig. 2 is the local enlarged diagram of the utility model.
Fig. 3 is the utility model schematic side view.
Fig. 4 is the vernier slice structural representation.
Fig. 5 is the measuring claw structural representation.
In the drawings 1, measuring claw 2, tape strip 3, vernier slice 4, drag knob 5, Flexible rule case.
Embodiment
Can be seen that by Fig. 1 the utility model is that the front end at the ordinary steel tape measure is added an end vernier slice, vernier slice can be mobile arbitrarily on tape strip.During use the front end of tape measure is fixed on an end of object, the pulling Flexible rule case, extract tape strip out, at the other end of fixed object, vernier slice is also moved to this place, by the comparison to vernier slice and tape strip high scale, seek the scale mark that tape strip overlaps with the vernier slice high scale, accurately measure the size of object, its length that is of a size of tape strip adds the length of reading on the vernier slice, and its measuring principle is identical with vernier caliper.
Fig. 2 is the enlarged drawing of tape strip front end, as seen from the figure, and the annexation of vernier slice and tape measure.
Fig. 3 is the utility model partial enlarged drawing, and the position of visible two measuring claws of figure is arranged, and a measuring claw is fixed on the front end of tape strip, and another measuring claw can move along with the movement of vernier slice.
When measuring diameter of a circle, a measuring claw is fixed on the circle, the traverse measurement pawl by two scales, is read diameter of a circle to circle.It is identical with the end measuring principle to measure two distance of round, all is to fix two ends by two measuring claws, measures distance.
Fig. 4 is the vernier slice structural representation, vernier slice adopts the stainless steel material of 0.01cm, be an arcuate structure in the middle of it, radian is identical with tape strip, the both sides flanging, the flanging place is circular arc, internal diameter is (L+0.005) cm, and L is the steel tape width, and gap width is 0.005 cm, so that vernier slice is in the cofree move left and right of tape strip, thereby obtain stable reading.
Fig. 5 is the structural representation of measuring claw, and when the moving cursor sheet, the spacing of two measuring claws changes thereupon, and the use measuring claw can be measured circle external diameter or two distance of round or do the end and measure.
