Abstract
The utility model discloses a kind of multi-functional registration compasses, belong to a kind of compasses.The compasses body that the utility model is made up of compasses head, rotating shaft and two rules and regulations arms; In the lower end of compasses head, digital display screen being installed, being provided with the angular transducer for gathering two rules and regulations arm opening angles at the back side of digital display screen; Two rules and regulations arms are all in flat, and symmetry is provided with lucite district on the top of two rules and regulations arms, and at lucite, district is marked with scale.Advantage: except having common calipers function, also can utilize rule arm when ruler picture straight line; The angle folded by two straight lines can be measured by two rule arms and angular transducer; The automatic measurement display of two rule arm angles and two rule arm bottom tip portion distance between two points is realized by sensor and the sub-display screen of number.
Description
Technical field
The utility model relates to a kind of compasses, specifically a kind ofly automatically can calculate angle, length and rule arm indicate graduation mark and can be used as ruler and to use and can the multi-functional registration compasses of numerical monitor measured value, belong to field of stationery.
Background technology
A course the most basic in mechanical major charts exactly, when using compasses construction, uses ruler instead because often measuring the radius of drawing requirement, regulates the angle of compasses, and error of long duration just slowly adds.Along with the development in epoch, the utility model can solve this loaded down with trivial details picture step, convenient and swift, improves drawing efficiency.
Summary of the invention
For the deficiency that prior art exists, the utility model object is to provide a kind of multi-functional registration compasses.
To achieve these goals, the technical solution adopted in the utility model is: comprise the compasses body be made up of compasses head, rotating shaft and two rules and regulations arms; In the lower end of compasses head, digital display screen being installed, being provided with the angular transducer for gathering two rules and regulations arm opening angles at the back side of digital display screen; Two rules and regulations arms are all in flat, and symmetry is provided with lucite district on the top of two rules and regulations arms, and at lucite, district is marked with scale.
Further: described angular transducer is by power supply and linear resistance testing circuit in series; Rotating shaft is provided with the adjustment resistance rule arm of synchronous two rules and regulations arm motions, described adjustment resistance rule arm is connected with linear resistance, and the current signal of testing circuit is sent to digital display screen process and the distance of the angle shown between two rule arms and two rule arm bottom tip portion point-to-point transmissions.
The beneficial effects of the utility model are: except having common calipers function, and rule arm also can be utilized when ruler picture straight line; The angle folded by two straight lines can be measured by two rule arms and angular transducer; The automatic measurement display of two rule arm angles and two rule arm bottom tip portion distance between two points is realized by sensor and the sub-display screen of number.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the compasses body that is made up of compasses head 1, rotating shaft 6 and two rules and regulations arms 3 of a kind of multi-functional registration compasses.In the lower end of compasses head 1, digital display screen 2 being installed, being provided with the angular transducer 5 for gathering two rules and regulations arm 3 opening angles at the back side of digital display screen 2; Two rules and regulations arms 3 are all in flat, and symmetry is provided with lucite district 4 on the top of two rules and regulations arms 3, is marked with scale in lucite district 4; Rule arm 3 easy to use as ruler setting-out with and two straight lines that utilize the limit of two rule arms 3 to fit when taking measurement of an angle need to measure folded by angle.
As shown in Figure 2, angular transducer 5 is by power supply 9 and linear resistance 8 testing circuit in series; Rotating shaft 6 is provided with the adjustment resistance rule arm 7 that synchronous two rules and regulations arms 3 move, described adjustment resistance rule arm 7 is connected with linear resistance 8, and the current signal of testing circuit is sent to digital display screen 2 and processes and the distance of the angle shown between two rule arms and two rule arm bottom tip portion point-to-point transmissions.
Wherein digital display screen 2 is divided into two regions, is respectively used to the angle and distance of display measurement.Resistance rule arm 7 relative rule arm 3 is regulated to launch the installation being conducive to reducing compasses length dimension and being convenient to angular transducer part more laterally.
Operation principle: arm 3 length adjustment should be advised to consistent by two in advance, to ensure measurement effect.Resistance rule arm 7 upper end is regulated to be connected with linear resistance 8, the expansion of rule arm 3 can drive and regulate resistance rule arm 7 to launch, and then resistance will change along with the expansion of compasses, while change in resistance also can there is corresponding change in electric current, the arc length regulating resistance rule arm 7 correspondence just can be calculated according to physical knowledge, angle-data folded by two rule arms 3 can be conversed according to arc length data, the length combining rule arm 3 again can calculate two rule arm 3 lower pointed end spacings, and the angle-data measured and range data all can be presented at above digital display screen 2.
The course of work: when bowlder drawn by these compasses, open two rule arms 3, can show the angle of expansion and the size of two rule arm 3 lower pointed end spacings automatically, when being deployed into required separation distance data (namely drawing radius of circle) and can drawing according to these data the circle of relevant radii; When measuring length or the distance between two points of certain line segment, only two rules and regulations arm 3 lower pointed end need be positioned at measurement point can directly draw length or distance from display screen; When needing picture straight line, use the lucite district 4 of rule arm 3; When needs measurement two included angle of straight line, measure two straight lines by required for the laminating of the outer side edges of two rules and regulations arms 3.
