Abstract
The invention relates to a spirit level. The evaluation of the spirit level for the inclination of planes with certain inclination angles is realized through accurate angle rotation of a spirit bubble capable of rotating in the spirit level, and meanwhile, the rotation operation of the spirit bubble can be facilitated due to arrangement of a driving wheel provided with prism bulges, so that the rotation angle is more accurate, and the operability is higher.
Description
Technical field
The present invention relates to a kind of surveyor's staff, belong to field of tool.
Background technology
Traditional surveyor's staff cannot real inclined-plane gradient accurate measurement.
Summary of the invention
The object of the invention is to: a kind of surveyor's staff that can measure inclined-plane gradient is provided.
The present invention realizes in the following way:
A surveyor's staff, comprises main body and is arranged on the spirit bubble in main body, described body interior is hollow, and described surveyor's staff also comprises spirit bubble governor motion and registration mechanism;
Described spirit bubble governor motion is arranged on body interior, described spirit bubble governor motion comprises support, rotor wheel, rotation axis, turning wheel, described spirit bubble is fixed on rotation axis by support, described rotation axis and main body are rotationally connected, on described support, be fixed with rotor wheel, the axis of described rotor wheel place plane and rotation axis is perpendicular, described rotor wheel diameter is greater than the length of spirit bubble, on described body, the plane machining of corresponding rotor wheel has at least one through hole, in described through hole, be provided with the axis turning wheel parallel with rotation axis, described turning wheel contacts with rotor wheel cylindrical,
Described registration mechanism comprises scale and pointer, and described rotation axis stretches out body and is fixedly connected with pointer, and described scale is annular, and it is the center of circle that annular be take the axle center of rotation axis.
As further innovation of the present invention, described rotor wheel surface is parallel to rotation axis and is provided with prism-shaped projection A, and described turning wheel surface is provided with the prism-shaped projection B corresponding with described prism-shaped projection.
As further innovation of the present invention, the longitudinal cross-section of described through hole and lateral cross section are trapezoidal, and described trapezoidal long base is positioned at main body outer wall, and the radius of described turning wheel is less than turning wheel axle center to the distance on trapezoidal long base.
Beneficial effect:
The present invention is by a spirit bubble that can rotate in chi, by its accurate angle rotation is realized to surveyor's staff for the assessment with the degree of tilt of certain inclination angle plane, the turning wheel that is simultaneously provided with prism projection can facilitate the operation of spirit bubble rotation, make the angle of rotation more accurate, operability is stronger.
Accompanying drawing explanation
Fig. 1 is cut-open view of the present invention.
Fig. 2 is that structure of the present invention is always schemed.
In figure: 1, through hole; 2, turning wheel; 3, rotor wheel; 4, connecting link; 5, spirit bubble; 6, rotation axis; 7, pointer; 8, support; 9, main body.
Embodiment
Below in conjunction with accompanying drawing, be described further:
As shown in Figure 1 and 2, a kind of surveyor's staff, the main body 9 that comprises two spirit bubbles 5 and surveyor's staff, main body 8 inside are hollow, at spirit bubble 5, by support 8 and rotation axis 6, rotate main body 9 inside are installed, support 8 is a garter spring that is fixed on spirit bubble 5 outsides, rotation axis 6 is vertical with the longitudinal axis of spirit bubble 5, rotation axis 6 stretches out main body outer wall, extension is fixed with pointer 7, the rotation axis 6 of take has circular scale line as the circular outer wall in main body 9 marks, external vertical at spirit bubble 5 is provided with an annular rotor wheel 3 in rotation axis 6, correspondence position in main body 9 with rotor wheel 3, be provided with a turning wheel 2, turning wheel 3 rotates the outer shell that is fixed on main body 9, position at the corresponding turning wheel 3 of the outer shell of main body 9, be provided with an indent through hole of being convenient to finger manipulation, turning wheel 3 is just fixed on indent through hole, make turning wheel 3 can not expose the top layer of main body 9, affect the grazing on the top layer of main body 9,
By rotary indicator or stir turning wheel and can realize the adjustment to spirit bubble angle, thereby whether the gradient of assessing some inclined-planes meets engineering demand.
