Abstract
The utility model provides a curve measuring tool with high measurement precision, simple structure and convenient utilization and aims at shortages existed in the prior art, which comprises a handle, a roller, a sensor and an intelligent calculator. The roller capable of rolling is connected to the upper portion of the handle, a measuring start line is arranged on the circumference of the roller, and the sensor capable of sensing rolling circles of the roller is disposed inside the roller. The sensor is electrically connected with the intelligent calculator via a conductor so as to transmit the rolling circles of the roller acquired by the sensor to the intelligent calculator, the intelligent calculator is arranged in the middle of the handle and used for calculating measured length via the rolling circles, and the intelligent calculator is further provided with a display for displaying length measurement results calculated by the intelligent calculator.
Description
Technical field
The utility model relates to a kind of survey instrument, refers in particular to a kind of curved measurement instrument.
Background technology
General accurate measurement for straight line of existing dimensional measuring instrument provides good scheme, still for the measurement of the length of curve of running into through regular meeting in life or the work, but rarely has desirable survey instrument.Therefore when measuring length of curve, the thinking of often taking to curve cut-off is carried out approximate measure to curve, but the scheme error is bigger like this, and the measurement high for the ask for something precision can't meet the demands.Therefore the later stage develops to serve by gear mechanism and rotates, and length of curve is converted to the curved measurement scheme of line measurement, and it finally also is to come indicating graduation by the gear driven pointer, and then shows measurement result.Though this survey instrument obtains more accurate relatively in the past measurement scheme to a certain extent, but because it is to adopt the gear mechanism transmission principle, not only have accidental coefficient in the whole process, the systematic error of this measurement scheme itself also is apparent in view simultaneously.Therefore a kind of measuring accuracy ideal curve survey instrument higher, easy to use is that fields of measurement is badly in need of.
The present utility model people has proposed the higher curved measurement scheme of a kind of measuring accuracy promptly at the problems referred to above.
The utility model content
The utility model is at the disappearance of prior art existence, and its fundamental purpose provides a kind of measuring accuracy height, curved measurement instrument simple in structure and easy to use.
For achieving the above object, the utility model adopts following technical scheme: a kind of curved measurement instrument, it is characterized in that: comprise handle, roller, inductor and intelligent computer, described handle top is connected with rotatable roller, this roller circumference is provided with one and measures start line, and this roller inside is provided with the inductor that can respond to the roller rolling number of turns; Described inductor is transferred to intelligent computer by lead and the intelligent computer roller rolling number of turns that is used for inductor is obtained that is electrically connected, this intelligent computer is arranged at above-mentioned handle middle part and is used for calculating measurement length by the rolling number of turns, and this intelligent computer also is provided with the measurement length result of display in order to show that intelligent computer is calculated.
Described roller circumferential wall is provided with integrated sheet big roller.
Described roller circumferential wall is provided with a circular orientation groove.
After the utility model adopts technique scheme, its beneficial effect is: roll along measuring curve by roller in the utility model, thereby measure roller along measuring the number of turns that curve rolled by the set inductor in roller inside, give intelligent computer with the data transmission of the rolling number of turns again, and thereby intelligent computer multiplies each other the roll number of turns and roller circumferential length of roller to obtain the higher length of curve data of precision, and finally the display by intelligent computer shows the high precision length of curve result who is obtained.Total is simple, and is easy to use, and systematic error is less, and then finally makes curved measurement obtain a higher measuring accuracy.

Embodiment:
Come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:
Be illustrated in figure 1 as embodiment 1 of the present utility model: a kind of curved measurement instrument, comprise handle 1, roller 2, inductor 3 and intelligent computer 4, described handle 1 top is connected with rotatable roller 2, these roller 2 circumference are provided with one and measure start line, and these roller 2 inside are provided with the inductor 3 that can respond to the roller 2 rolling number of turns; Described inductor 3 is electrically connected by lead 5 and intelligent computer 4 and is used for inductor 3 roller that the obtains 2 rolling number of turns are transferred to intelligent computer 4, this intelligent computer 4 is arranged at above-mentioned handle 1 middle part and is used for calculating measurement length by the rolling number of turns, and this intelligent computer 4 also is provided with the measurement length result of display in order to show that intelligent computer 4 is calculated.
As shown in Figure 2, embodiment 2 of the present utility model is with the difference of embodiment 1: described roller circumferential wall is provided with integrated sheet big roller 6.Therefore when curve to be measured is positioned on some long and narrow raceway grooves, can embeds in the raceway groove by this sheet big roller and carry out tolling measurement, and then obtain good measurement effect.
As shown in Figure 3, embodiment 3 of the present utility model is with the difference of embodiment 1: described roller circumferential wall is provided with a circular orientation groove 7, when curve to be measured is positioned at some faces and delivers personally the seamed edge place that connects, can be by seamed edge being embedded in the detent 7 and then accurately measurement of scroll wheel 2 realizations.
Of the present utility model focusing on, roll along measuring curve by roller 2, thereby measure roller 2 along measuring the number of turns that curve rolled by roller 2 inner set inductors 3, give intelligent computer 4 with the data transmission of the rolling number of turns again, and thereby intelligent computer 4 multiplies each other the roller 2 rolling number of turns and roller 2 circumferences and obtains the higher length of curve data of precision, and finally the display by intelligent computer 4 shows the high precision length of curve result who is obtained.Total is simple, and is easy to use, and systematic error is less, and then finally makes curved measurement obtain a higher measuring accuracy.
The above, it only is preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
