Abstract
The utility model relates to a laser mapping angle scale, comprising a reference scale, a measurement scale, a laser generator, an angle sensor and a digital readout screen. One ends of the reference scale and the measurement scale are hinged; and the laser generator and the angle sensor are configured on the measurement scale; and the digital readout screen displays an angle value. The laser mapping angle scale is characterized in that a square shell is arranged on a laser device; a positioning groove is correspondingly arranged at the front end of the measurement scale; and the laser device is fixedly arranged in the positioning groove on the measurement scale through a screw. The laser mapping angle scale provided by the utility model has the beneficial effects that the laser mapping angle scale has a compact structure; after the laser device is mounted, corrected and calibrated, a laser beam is stable in precision; an angle between objects can be measured in a long distance and high precision manner, and the accurate lineation between long-distance objects can be realized; and meanwhile, a laser lens is difficult to damage and is convenient to carry.
Description
Affiliated technical field
The utility model relates to technical field of mapping, and is relevant with a kind of instrument that takes measurement of an angle, and especially relates to the laser mapping bevel protractor.
Background technology
Bevel protractor is the surveying and mapping tool of using always, and its primary structure normally is made up of the ruler that two one ends are hinged; During use, a ruler is as station meter, and another ruler rotates as dip stick around pin joint.Existing various bevel protractor is unable to do what one wishes with line to the measurement of angle between remote objects because of self size restrictions, especially when need marking lengths during much larger than dip stick self length, and the operation of can't ruling accurately continuously.For solving long-range measurement of angle and line problem, at present known have the bevel protractor that uses laser, but these bevel protractors remain in defective.Like publication number is the patented claim disclosed " multifunctional angular chi " of CN2697584Y; The bevel protractor of this patented claim is provided with laser instrument and laser switch at an end of its station meter, and obviously this laser instrument institute emitted laser of being located on the station meter can't be followed the tracks of different measurement and the line operations that need under the mapping angle.And for example notification number is the patent disclosed " laser angle chi " of CN2694227Y; This patent is provided with arc groove having on the set square of base; On the number of divisions of protractor is arranged, the hand rest of laser instrument rotates with it, to its angle that number of divisions is read point or the line and the basic point of measured object in the arc groove both sides; This bevel protractor not only takes measurement of an angle, and scope is little, the measurement display precision is low, and uses and carry inconvenience.Notification number is the patent disclosed " laser mapping bevel protractor " of CN201081701Y for another example; This patent is disclosing the scheme that adopts angular transducer and separate type laser instrument; Though this scheme improves to some extent, the laser instrument that separates is lost easily, and it is stable that installation accuracy also is difficult to keep.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art existence, proposes a kind of laser mapping bevel protractor, and this bevel protractor not only can carry out the remote measurement angle and grow the distance line, and the apparent precision of survey is high, easy to carry and be difficult for impaired.
In order to reach above purpose, the utility model is realized through following technical scheme:
The laser mapping bevel protractor comprises station meter, dip stick; Laser generator, angular transducer and digital display screen, said station meter and dip stick one end are hinged; Described laser generator and angular transducer are configured on the dip stick, described digital display screen angles of display value; It is characterized in that: described laser instrument is provided with square casing, and described dip stick front end is to locating slot should be arranged, and described laser instrument is through in the chimeric locating slot that is fixed on the dip stick of screw.
Further, described locating slot is provided with the breach of stepping down.
Further, an end of said laser generator is provided with a camera lens and a laser generation switch button; Described camera lens is lower than the surface of shell of laser instrument slightly.
Further, said station meter cross section is roughly L-shaped, is provided with horizontal vacuole and vertical vacuole.
The beneficial effect of the utility model is, compact conformation, and laser instrument is once installing after check and correction demarcates; The laser beam stable accuracy; Can realize the angle between the remote high-precision object and carry out the accurate line between remote object that the laser camera lens is difficult for impaired, easy to carry simultaneously.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Consult Fig. 1 to Fig. 4, the embodiment of the utility model provides the laser mapping bevel protractor, comprises station meter 1; Dip stick 2; Laser generator 3, angular transducer (not drawing among the figure) and digital display screen 4, said station meter 1 is hinged with dip stick 2 one ends; Described laser generator 3 is configured on the dip stick 2 described digital display screen 4 angles of display values with angular transducer; Described laser instrument 3 is provided with square casing 30, and described dip stick 2 front ends are to locating slot 20 should be arranged, and described laser instrument 3 is through in the screw 5 chimeric locating slots 20 that are fixed on the dip stick 2.
As preferred embodiment, described locating slot 20 is provided with the breach 21 of stepping down.After described laser instrument 3 is installed on the dip stick 2, can carry out close adjustment and demarcation, the more split type laser instrument of its bearing accuracy is higher more stable.
As preferred embodiment, an end of said laser powder producer 3 is provided with a camera lens 31 and a laser generation switch button 32; Described camera lens 31 is lower than housing 30 surfaces of laser instrument slightly, can protect laser camera lens 31 to be difficult for being scratched impaired like this.Further, described button 32 employing plane soft-touch type buttons.
As preferred embodiment, said station meter 1 cross section is roughly L-shaped, and available aluminium section bar processing is provided with horizontal vacuole 10 and vertical vacuole 11.
The operation of the utility model is following:
When need are measured between an object and another remote objects angle; The reference field of the station meter of the utility model laser mapping bevel protractor is abutted on to be measured of this Measuring Object; Open laser generator and send laser; Rotate dip stick, laser is followed when rotating, and accurate angle degree can be read from device for digit-displaying immediately between the two articles of measuring through angular transducer.
When between need are being positioned at the two remote objects of same plane (like metope etc.), ruling, the laser beam irradiation of rotation on the remote objects after, can between two remote objects, carry out long-range accurate line operation along the trace that laser beam stays in the plane.
When not in use, the dip stick that closes gets final product, and the camera lens of laser generator is lower than the surface of shell of laser instrument slightly, is not easy to sustain damage, and whole bevel protractor seems that also profile is simple and is easy to carry about with one.
The above content that discloses; It is the preferable specific embodiment of the utility model; The purpose of all and the utility model is equivalent or impartial content with the effect that can reach; And for those skilled in the art can unlabored simple and easy modification, modification, improvement or variation, all should not break away from the patent right scope of opinion that the utility model is contained.
