Abstract
The utility model discloses a measuring tool for measuring horizontal angles. A shaft fixed in a hollow body is provided with a graduated scale which can be rotated by winding the shaft. The hollow body is filled with liquid, and the graduated scale is matched with a floating body. When a measured object is not in a horizontal angle, the graduated scale generates rotation relative to a ruler body by using a pole point as the centre under the action of floating power and a pole angle degree is formed and is displayed by that the starting point of the ruler body is corresponding to the graduated line and the number of the graduated scale. Meanwhile, the pole angle degree is equal to the level degree of the measured object.
Description
Present technique relates to a kind of measurer of measuring level angle.
Existing surveyor's staff and level meter are to come whether level or vertical of Measuring Object by bubble displacement in it self water pipe, can not show its level angle.
The utility model purpose provides a kind of not only energy measurement object whether level or vertical, accurately the buoyancy aid level angle instrument of Measuring Object level angle.
The utility model purpose is achieved in that
Be fixed on the axle of the axle in the ducted body graduated scale that can sway is installed.Graduated scale mark has reticule and in corresponding " 0 " index of reticule and other number.Ducted body top is manufactured and has been marked with transparent material in the corresponding initial point line of graduated scale exponential line.According to the plane polar coordinates analysis, the axle center is a limit, and the ray that " 0 " dotted line of graduated scale surface mark and limit form is pole axis or line segment, the ray that initial point line that marks on the ducted body and limit form is another line segment, when two line segments overlapped, polar angle was zero, and the chi body is a horizontality.Be perfused with liquid in the ducted body, graduated scale (on the position of setting) disposes buoyancy aid.When testee is not level angle, graduated scale is subjected to buoyancy function to be that the center is relative with the chi body with the limit to rotate, rotate back two line segments and form the polar angle number of degrees, these number of degrees are the horizontal angle number of degrees of testee by the reticule and digital demonstration of chi body initial point mapping graduated scale simultaneously.
Be further elaborated below in conjunction with accompanying drawing:
Fig. 1, Fig. 2 are respectively vertical cut-away view of chi body cross-shaped symmetrical axis.
With reference to accompanying drawing, among Fig. 1: 1. chi body; 2. rivet; 3. sieve bolt; 4. spring; 5. cover plate; 6. upper shell; 7. graduated scale; 8. buoyancy aid; 9. axis hole; The axle; 11. rivet; 12. lower house; 13. liquid; 14. shutoff; Among Fig. 2: 15. bobbin terminals.
Graduated scale (7) is provided with " V " oblique crank Z hole (9).Graduated scale (7) is installed on the axle (10), and the bobbin terminal (15) that linear axes (10) two ends are provided with is fixed in upper shell (6) and the specific groove in lower house (12) joint portion.Upper shell (6) is the transparent material manufacturing.Upper shell (6) fastens sealing with lower house (12), fixes with rivet (11) and form a ducted body.The hollow endosome is perfused with liquid (13).Ducted body is provided with liquid injection port, seals with shutoff (14) shutoff after the fluid injection.Cover plate (5) is fixed on the chi body (1) with rivet (2), and upper shell (6) is connected and fixed on cover plate (5) with gong bolt (3), spring (4) with the ducted body that lower house (12) is formed.Whether consistent turn gong bolt (3) can be regulated the angle between chi body (1) and graduated scale (7) pole axis, play chi body (1) own level and mark corrective action buoyancy aid (8) and be subjected to buoyancy function to make pole axis vertical with surface level, and angle is 90 degree.The buoyancy aid (8) of configuration changes balance weight body into and removes the material cost in the graduated scale (7), and life of product is changed into by buoyancy and is subjected to vertical power effect can produce approximate effect not as outside the buoyancy aid (7), uses balance weight body to replace as the material in the present technique.Mark has reticule and number in graduated scale (7) upper surface.For ease of observation, graduated scale (7) can three mark score lines (front, back, top).The reticule mark that the pole axis straight angle is corresponding with two vertical angles has " 0 " number.But the level angle of the comprehensive Measuring Object of the utility model 360 deg.The utility model can replace horizontal tube and be installed in the most of parts employing of this legend nonmetallic materials on some professional lining instruments, and profile line is drawn by nonmetallic materials and transparent material regulation only as structural representation.
The utility model is simple in structure, and accurately the level angle of Measuring Object is easy to use in practical operation.
