Embodiment
Each Reference numeral title in accompanying drawing is:
Flexible rule case 1, square hole 11, tape measure core 2, tape 3, guide groove 4, scaleplate 5, spring 6, perpendicular baffle plate 7.
Below in conjunction with accompanying drawing, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
As shown in Figure 1, it can measure the structural representation of the tape measure of irregularly shaped object for the utility model; Wherein, the tape measure can measuring irregularly shaped object comprises: Flexible rule case 1, square hole 11, tape measure core 2, tape 3, guide groove 4, scaleplate 5, spring 6, perpendicular baffle plate 7.
Flexible rule case 1 is a housing, and concrete shape can be square, circular or other shapes, is fixed wtih tape measure core 2 inside it; Tape measure core 2 is a cylindrical object, and its two ends are separately fixed on the inwall of Flexible rule case 1, and vertical with two inwalls; Tape is the flat ribbon that can bend arbitrarily, and thickness is even, so just can irregularly shaped object show bend arbitrarily, to measure irregularly shaped object, it is wrapped on tape measure core 2, and one end is fixed on tape measure core 2, and Flexible rule case 1 is stretched out in one end; Guide groove 4 has two, and be separately fixed on two inwalls vertical with tape measure core 2, its one end is connected with tape measure core 2, and one end is connected with square hole 11, and scaleplate 5 can be allowed to be free to slide between tape measure core 2 and square hole 11; Scaleplate 5 one end is in Flexible rule case 1, and one end is stretched out outside Flexible rule case 1 by square hole 11, and both sides are respectively in two guide grooves, and the one end in Flexible rule case 1 is connected with perpendicular baffle plate 7; Perpendicular baffle plate 7 is connected with scaleplate 5 one end in Flexible rule case 1, and it is vertical with scaleplate 5, and side is concordant with the end face of scaleplate 5, and contacts with tape 3, and perpendicular baffle plate 7 another side is connected with spring; Spring 6 one end is connected with perpendicular baffle plate 7, and one end is connected with the Flexible rule case 1 below square hole 11; Square hole 11 is in the side of Flexible rule case 1, and its height is identical with tape measure core 2.
Guide groove 4 is line segment, and its one end is connected with tape measure core 2, and it holds scaleplate 5, and scaleplate 5 slides in guide groove 4, the extension line of its length through tape measure core 2, can in guide groove 4 along guide groove 4 carry out near or away from the slip of tape measure core 2.
Tape 3 is wrapped on tape measure core 2, is coiled into circle, and the tangent plane being clipped in the tape 3 in the middle of two guide grooves 4 is vertical with guide groove 4, also vertical with scaleplate 5; Perpendicular baffle plate 7 is vertical with scaleplate 5, parallel with the tangent plane of the tape 3 be clipped in the middle of two guide grooves 4.
Spring 6 between erecting below baffle plate 7 and square hole 11 is in compressive state always, and the spring 6 of compression promotes perpendicular baffle plate 7 and slides to tape measure core 2 with scaleplate 5, is adjacent to until erect the side of baffle plate 7 and the end face of scaleplate 5 and the tape 3 be clipped in the middle of two guide grooves 4.Spring 6 is in compressive state always, and therefore the perpendicular side of baffle plate 7 and the end face of scaleplate 5 can keep being adjacent to the tape 3 be clipped in the middle of two guide grooves 4.
As shown in Figure 2, it can measure the lateral parts structural representation of the tape measure of irregularly shaped object for the utility model; Wherein, guide groove 4 is fixed on inside Flexible rule case 1, and two guide groove height are identical; The both sides of scaleplate 5, respectively in two guide grooves 4, ensure that scaleplate 5 moves along guide groove 4; Perpendicular baffle plate 7 is fixed on below scaleplate 5, is connected with spring; The width of perpendicular baffle plate 7 is less than the width of scaleplate 5, is also less than the minor increment between two guide grooves 4, would not stops the slip of scaleplate 5 along guide groove 4 like this.
As shown in Figure 3, it can measure the scale schematic diagram of the scaleplate of the tape measure of irregularly shaped object for the utility model; Wherein, because the physical length of the tape of same thickness is different on different radii, scale value increases successively from left to right on scaleplate 5, and scale distribution and uneven, the scale of identical difference only has more and more intensive from a left side on scaleplate 5, and the distance between two scales of identical difference is shorter and shorter.
When tape 3 has just stretched out Flexible rule case 1, the number of turns that tape 3 is wound around on tape measure core 2 is maximum, tape circle is the thickest, the girth of outermost layer tape is the longest, now spring 6 is compressed to maximum, and the length that scaleplate 5 stretches out Flexible rule case 1 is the longest, and the scale on scaleplate 5 is the most sparse, scaleplate 5 is 0 with the scale of Flexible rule case 1 contact position, and now scaleplate 5 reading is 0; Along with tape 3 is extracted out, the number of turns that tape 3 is wound around on tape measure core 2 reduces, tape circle is thinning, the girth of outermost layer tape also shortens, scaleplate 5 and the direction of perpendicular baffle plate 7 along guide groove 4 to tape measure core 2 under the effect of spring 6 are moved, and scaleplate 5 stretches out the portion rebounds of Flexible rule case 1, and the scale on scaleplate is intensive gradually, scaleplate 5 increases with the scale of Flexible rule case 1 contact position, and the reading of scaleplate 5 increases.
Spring 6 is in compressive state always, makes scaleplate 5 and perpendicular baffle plate 7 be close to tape 3 between guide groove 4 always, decreases measuring error, improve measuring accuracy.
Measure irregularly shaped object, during girth as curve, can extract tape 3 out, make the tape 3 that can bend arbitrarily be adjacent to curve, until one week, record the reading of scaleplate 5 before and after extraction tape 3, the difference of two readings is the girth of curve.
Tape 3 can bend arbitrarily, therefore can be adjacent to the irregularly shaped object that will measure, and reduces the error measured, and improves the precision measured.
In addition, can be with a scale in tape 3, also can not be with a scale, can direct direct reading from scaleplate 5, when so just making to measure, reading is very convenient.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for the utility model, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that the utility model claim limits to it, amendment, even equivalence, but all will fall in protection domain of the present utility model.
