Abstract
The utility model provides a protractor, it is main includes angulation board, laser device, the design of angulation board is semicircle - shaped, and the laser device is rectangular form, and the design of laser device one end has the laser source, and the other end and angulation board articulate in the centre of a circle of angulation board department through the pivot, still are equipped with horizontal bubble appearance and compass on the angulation board. The laser device is provided with power, luminotron and switch. The beneficial effect of the utility model: a protractor, as an organic whole with spirit level, bevel protractor, compass design, can carry out the accurate measurement to object contained angle angle, position position angle and plane inclination, can also carry out level determination, fixing by cross bearings to remote object, increase with the service function that improves present angle measuring tool, carry convenient to use.
Description
Technical field
The utility model relates to survey instrument field, particularly relates to a kind of protractor.
Background technology
In the activities in production such as building operation, machine-building, ground observation drawing, often need the measurement carrying out object angle, taking measurement of an angle conventional is the instruments such as bevel protractor, semi-circle ruler, total powerstation.The instrumental function taken measurement of an angle at present is more single, is confined to the measurement of angle angle, does not possess the measurement function to aspects such as objective direction angle, horizontal tilt angles, can not carry out level determination, fixing by gross bearings to remote object.Therefore, often need to prepare the multiple types of tools such as measurement of angle, measurement of bearing, horizontal degree measurement, instrument and equipment cost is high, carries and uses inconvenience.
Summary of the invention
The purpose of this utility model: the deficiency overcoming existing angle measurement tool function singleness, provides that a kind of structure is simple, diverse in function, angle measurement tool easy to carry.
Technical solutions of the utility model: a kind of protractor, mainly comprise Angle protractor, laser aid, Angle protractor is designed to semi-circular shape, laser aid is strip, laser aid one end is designed with lasing light emitter, the other end and Angle protractor are hinged on the circle centre position of Angle protractor by rotating shaft, and Angle protractor is also equipped with horizontal bubble instrument and compass.
Further, described laser aid is provided with power supply, luminotron and switch.
The beneficial effects of the utility model: a kind of protractor described in the utility model, level meter, bevel protractor, compass are designed to one, Measurement accuracy can be carried out to object angle angle, position of orientation angle and flat inclination, level determination, fixing by gross bearings can also be carried out to remote object, increase and improve the using function of existing angle measurement tool, portably use conveniently.
Accompanying drawing explanation
Fig. 1 is a kind of protractor schematic diagram of the utility model.
In figure: 1. Angle protractor, 2. compass, 3. laser aid, 4. horizontal bubble instrument, 5. rotating shaft.
embodiment:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in the figure, a kind of protractor, mainly comprise Angle protractor 1, laser aid 3, Angle protractor 1 is semi-circular shape, laser aid 3 is in strip, laser aid 3 one end is designed with lasing light emitter, and the other end and Angle protractor 1 are hinged on the circle centre position of Angle protractor 1 by rotating shaft 5, Angle protractor 1 is equipped with horizontal bubble instrument 4 and compass 2.Laser aid 3 is provided with power supply, luminotron and switch.
By horizontal bubble instrument 4, Angle protractor 1 is transferred on surface level, utilizes the scale on compass 2, Angle protractor 1, Measurement accuracy can be carried out to object angle angle, position of orientation angle and flat inclination; Open laser aid 3 switch, according to the laser beam of its injection, the level of remote object and the position of orientation of relative measurement point can be determined.
