Embodiment

The utility model provides a kind of compact construction, Novel distance measuring device easy to use, for making object, technical scheme and advantage more explicit, being described in further detail by the utility model below in conjunction with accompanying drawing and embodiment, its embodiment is:

A kind of Novel distance measuring device as shown in Figure 1, comprises base (1), vertical rod (2), tightening screw (3), calculating device (4), expansion link (5), screw (6), surveillance mirror (7), laser pen (8), screw (9), the secondary chi (10) of angle measurement, angle measurement main scale (11). It is characterized by: described vertical rod (2) and base (1) are bolted fixing, vertical rod (2) is equipped with calculating device (4), automatically tries to achieve the distance between testee by the vertical range of the rotation center to ground that input angle measurement device and the angle value surveyed between laser and vertical bar. Vertical rod (2) hollow, expansion link (5) dimension ratio vertical rod (2) is slightly little, can moving up and down in vertical rod (2), vertical rod (2) is fixed by tightening screw (3) with expansion link (5). Described expansion link (5) is marked with scale, it is possible to read the vertical range of rotation center to ground of angle measurement device. Described expansion link (5) is mounted with a surveillance mirror (7), whether can be irradiated to target measuring point by remote observation laser. Described angle measurement main scale (11) is fixed on expansion link (5) by two screws (6), and 0 scale marks ensured on angle measurement main scale (11) during installation keeps vertical relation with ground. The secondary chi (10) of described angle measurement is hinged by screw (9) and angle measurement main scale (11), the secondary chi (10) of angle measurement can be rotated around hinged screw (9), the secondary chi (10) of angle measurement is fixed with laser pen (8), 0 scale marks of the light that laser pen (8) is launched chi (10) secondary with angle measurement overlaps, and laser pen (8) can rotate with the rotation of the secondary chi (10) of angle measurement.

For the service requirements of the crowd of satisfied different height, expansion link (5) is marked with scale, being characterized in that scale reading is increase gradually from top to bottom, bottom expansion link, namely institute's marking angle value can be the vertical range of rotation center to ground of angle measurement device.

Angle measurement device of the present utility model as shown in Figure 2, comprise angle measurement main scale (11) and secondary chi (10) two portions of angle measurement, the measurement of angle scope of angle measurement main scale (11) is 0-90 degree, the secondary chi (10) of angle measurement is 50 calibration, when 0 scale marks of angle measurement main scale (11) and the secondary chi (10) of angle measurement aligns, 50 scales of the secondary chi (10) of angle measurement face 49 degree of positions of angle measurement main scale (11), namely 1 degree is divided into 50 points by the secondary chi (10) of angle measurement, secondary chi (10) each scale of angle measurement represents 0.02 degree, thus the measuring accuracy making angle measurement device brings up to 0.02, measurement angle is accurate.
