Abstract
A goniometer comprises a straight rod and a handle that are mutually and vertically arranged. The intersection of the straight rod and the handle is a vertical point, and the lower side of the straight rod is provided with a protractor, of which the center coincides with the vertical point in position. The vertical point is fixedly provided with a rope of which the lower end is provided with a heavy object. The length of the handle is larger than that of the rope. The goniometer is simple in structure, practical in functions, low in manufacturing cost, convenient for operation and capable of fast and roughly measuring the inclination of a larger object.
Description
Technical field
The utility model relates to a kind of angular instrument.
Background technology
When thinking the gradient of rough measure larger object at present, often need be by complicated measuring instrument, these measuring instrument costs are higher, and measure very accurate, but under situation mostly, we do not need to measure so accurate.
The utility model content
The utility model purpose is to provide a kind of angular instrument simple in structure.
To achieve these goals, the utility model adopts following technical scheme: angular instrument, comprise mutual vertically disposed straight-bar and handle, straight-bar and handle infall are vertical point, the downside of straight-bar is provided with protractor, the center of protractor overlaps with the vertical point position, and the vertical point place is fixed with rope, and the lower end of rope is provided with weight.
The length of described handle is greater than the length of rope.
The utility model is simple in structure, function is practical, and low cost of manufacture is easy to operate, apace the degree of tilt of rough measure larger object.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, angular instrument comprises mutual vertically disposed straight-bar 1 and handle 3, straight-bar 1 and handle 3 infalls are vertical point, and the downside of straight-bar is provided with protractor 2, and the center of protractor 2 overlaps with the vertical point position, the vertical point place is fixed with rope 4, and the lower end of rope 4 is provided with weight 5.The length of handle 3 is greater than the length of rope 4.
When measuring, adjust straight-bar 1, straight-bar 1 is overlapped with tested inclined side, at this time weight 5 is at the action of gravity lower swing, and rope 4 just can be read from protractor with the angle of handle 3, and this angle is exactly the angle of tested inclined side and horizontal direction.
Claims (2)
1. angular instrument, it is characterized in that: comprise mutual vertically disposed straight-bar and handle, straight-bar and handle infall are vertical point, the downside of straight-bar is provided with protractor, the center of protractor overlaps with the vertical point position, and the vertical point place is fixed with rope, and the lower end of rope is provided with weight.
2. angular instrument according to claim 1 is characterized in that: the length of described handle is greater than the length of rope.
