Abstract
The utility model relates to a pointer reading calculating level. The middle and the end parts of the level rod of the level are respectively provided with a reading scale and a centering pointer whose one end is provided with a plumb counterweight pointer; the other end of the centering pointer is provided with a lightweight pointer. The tips of the pointer arranged at both ends are in the same straight line with the center of a centering hole. The straight edge of the level rod is stuck to the vertical down direction of the plumb balance weight pointer arranged on the measured surface, and indication can be read by the lightweight pointer. The overall error of the measuring segment can be calculated by the difference of the center circle reading and the end circle reading.
Description
The various surveyor's staffs of public use at present all are to utilize a glass tube that the mercury bubble is housed to be installed on the chi bar of surveyor's staff, and this surveyor's staff can only approximately be estimated and whether level.Be not only and use limitation big, and bad easily the appearance than mistake, also have result of use bad, people do not like to use but do not have other to substitute to exempt to force usefulness.
Between like this, I have invented a kind of pointer reading and have calculated surveyor's staff.
The utility model is realized as follows: introduce in detail below in conjunction with accompanying drawing:
Fig. 1 is that whole signal of the present utility model, Fig. 2 are the overall schematic of frame of reference.
Horizon rule chi bar (1) can adopt metal and nonmetallic materials to make, requirement is made into cuboid, length is not waited by 300mm--800mm, wide about 50mm--600mm, thickness is about 25mm--35mm, thickness direction up and down two limit requirements is absolute straight and not yielding, and width is for frame of reference (shown in Figure 2) is installed. Centre position and a left side (or right) end position at chi bar (1) are respectively opened an open-work for installing Frame of reference (2), (3), they use respectively tapping screw (4) to be fixed on the chi bar (1), and each frame of reference is fixed on four angles with four tapping screws (4). Centering pointer (5) passes on the circle center hole that internal point is fixed in forward and backward reading scale (7) and (6) with horizontal carefully axle (8), reserve suitable slit between the forward and backward reading scale, centering pointer (5) can get final product around the thin axle of horizontal stroke (8) Free, centering pointer (5) one ends are vertical counterweight pointer, and the other end is the lightweight pointer. Forward and backward reading scale utilizes connecting plate (9), (10) to be connected and fixed. (2), (3) frame of reference is identical, requires the circle center hole line on two frame of reference scales must be parallel in two limits of the thickness direction of chi bar (1) during installation, 0 and 90 lines must be perpendicular to two limits of thickness direction on the reading scale.
During use this horizon rule chi bar (1) is close on the surface of measured object, the vertical counterweight pointer of the centering pointer (5) in the frame of reference will vertically point to the below, light-duty pointer just can read number come on the reading scale, and can determine the direction of deviation, the length overall of the sin upper tested segment on duty of the difference of light-duty pointer indication position readings can be obtained the concrete deviation of tested segment on two reading scales.
Claims (1)
1, a kind of reading calculates surveyor's staff, it is characterized in that: at the middle position and the end position of surveyor's staff chi bar, each installs a reading scale and a centering pointer, reading scale and the supporting section center that is installed in surveyor's staff chi bar of centering pointer, one end of centering pointer is a vertical counterweight pointer, and the other end is the lightweight pointer.
