Abstract
The utility model provides a geomagnetic horizontal angle measurer, which belongs to the measuring instrument. The geomagnetic horizontal angle measurer mainly adopts a rectangle basal body which is provided with a geomagnetic pointing needle which is provided with an adjustable dial and a circular level. When the measuring straight edges of the basal body are respectively coincident with two vertical surfaces of a measured angle, the angle of a measured horizontal angle can be read following an included angle which is formed by the rotation of the basal body by the geomagnetic pointing needle and the adjustable dial. The geomagnetic horizontal angle measurer has good effect on conveniently and accurately measuring the horizontal included angle of two vertical surfaces of a building element, etc.
Description
The utility model belongs to a kind of level angle survey and establishes instrument.
In building engineering construction, often need to survey the horizontal sextant angle of establishing a certain member two vertical planes, commonly used is the inside and outside try square of construction work, its measurement range is ± 5mm, be equivalent to 85-95 degree angle, can't establish with the try square survey exceeding obtuse angle or the acute angle of surveying the scope of establishing, and utilize the inside and outside try square of construction work to survey when establishing angle, the levelness that try square is placed utilizes level tube to show, what level tube showed is the levelness that unidirectional levelness can not demonstrate whole try square place face, and survey is established not accurate enough.Up to the present, also do not have to survey accurately, easily the special-purpose angle survey that sets out the interior horizontal sextant angle arbitrarily of 0-360 scope and establish instrument.
The purpose of this utility model is: provide a kind of earth magnetism level angle of establishing 0-360 degree angular range of surveying accurately, easily to survey and to establish instrument.
For reaching above-mentioned purpose, the technical measures that the utility model is taked are: point to a pin and a circular bubble but establish an earth magnetism that has dispatcher's board (branch divides the 0-360 degree into) on rectangular base of employing, when survey is established straight flange and is coincided with tested two vertical planes of establishing angle respectively, but earth magnetism points to fixing sensing of pin and the angle of dispatcher's board with matrix rotation formation, exactly the tested numerical value of establishing horizontal angle.
The earth magnetism level angle that the utility model provides is surveyed and is established instrument, surveys and establishes angular range between the 0-360 degree, and it is big than try square inside and outside the construction work to survey the scope of establishing; The levelness of matrix is to carry out the control of two-way plane formula by circular bubble, than the level pipeline precise control of try square inside and outside the construction work many; Simultaneously, the utility model is not limited by the measured angle length of side, and easy to use, survey is established accurately.
Below in conjunction with accompanying drawing and enforcement the utility model is described further.
(1) establishes the rectangular base of straight flange (2) for having a survey among the figure, points to a pin (3) and a circular bubble (4) but be provided with an earth magnetism that has dispatcher's board.
When angle is established in survey, straight flange (2) is established in survey leaned against on measured angle one vertical plane, and make circular bubble (4) level, promptly the circular bubble bubble is placed in the middle.But regulate dispatcher's board earth magnetism sensing pin (3) and scale 0 scale mark are coincided, make it to make zero.Be rotated counterclockwise then to survey and establish straight flange and overlaps, but the sensing shape that dispatcher's board 0 scale mark turns clockwise with matrix and earth magnetism sensing pin is fixed at this moment in an angle, exactly the tested angle value of establishing with another vertical plane of being established the angle.
The utility model can use non-ferrous material such as plastics, fiberglass, aluminium alloy, timber to make; Size is advisable with 150mm (length) * 40mm (wide) * 10mm (height); But its precision is determined by graduation of dispatcher's board angle and circular bubble precision.
Claims (4)
1, a kind of earth magnetism level angle is surveyed and established instrument, it is characterized in that: the ground magnetic degree is surveyed to establish instrument rectangular base (1) but be provided with an earth magnetism that has dispatcher's board and is pointed to a pin (3) and a circular bubble (4).
2, instrument is established in described earth magnetism level angle survey according to claim (1), it is characterized in that: have a survey to establish straight flange (2) on the rectangular base (1).
3, survey according to the described earth magnetism level angle of claim (1) and establish instrument, it is characterized in that: but the earth magnetism that has a dispatcher's board points to the adjustable circle division scope of pin (3) is the 0-360 degree.
4, establish instrument according to described the survey at the magnetic level angle of claim (1), it is characterized in that: circular bubble (4) parallels with rectangular base (1) upper surface.
