Abstract
The utility model relates to an annular levelling instrument, comprising a levelling instrument base and an annular liquid bubble tube arranged on the levelling instrument base, wherein the section of the annular liquid bubble tube is round; a indicating liquid is arranged inside the annular liquid bubble tube; the indicating liquid just covers the bottom of the annular liquid bubble tube when the annular liquid bubble tube is horizontal. In order to further directly read the included angle between the to-be-tested surface and the horizontal plane, a graduated disk is arranged at the side of the levelling instrument; a scale pointer is arranged on the center of the graduated disk through a rotating shaft; the pointer is kept vertical to the horizontal plane under the gravity action. The annular levelling instrument is arranged into the annular shape by changing the shape of the traditional levelling instrument, and the angle does not need to be always adjusted when the annular levelling instrument is used, and just needs to be placed on the to-be-tested ground.
Description
Technical field
The utility model relates to a kind of building frock, is specifically related to a kind of annular surveyor's staff.
Background technology
Surveyor's staff is mainly used to detect or measure horizontal and vertical degree, and surveyor's staff, with spirit bubble, can be used for inspection, surveys reason, and whether commissioning device installs level.Use during as pump levelling capturing such as nuclear power plant equipment.Can be divided into the plurality of specifications such as aluminum alloy square cast, I shape, die-casting die, shaped plastics; Length is many specifications from 10CM to 250CM; The flatness of surveyor's staff material and air level quality, determined accuracy and the stability of surveyor's staff.More well-known in world wide is the brands such as Israel KAPRO, German surveyor's staff, Austria.Surveyor's staff for checking, measure, line, equipment are installed, the construction of Industrial Engineering.
But traditional horizontal linear formula surveyor's staff always needs continuous adjusting angle in use, is unfavorable for the raising of efficiency.
Utility model content
The technical problems to be solved in the utility model is: proposing one does not need adjusting angle, only needs the simple annular surveyor's staff of placing.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of annular surveyor's staff, comprise surveyor's staff pedestal and be arranged on the annular vacuole pipe on described surveyor's staff pedestal, the cross section of described annular vacuole pipe is circular, in described annular vacuole pipe, be filled with horizontal indicator solution, in the time of described annular vacuole pipe level described in horizontal indicator solution just cover the bottom of described annular vacuole pipe.
In order further directly to read the angle between being tested surface and surface level, the side of described surveyor's staff is provided with index dial, and the center of described index dial is provided with tuning drive gear by rotating shaft, and described pointer keeps vertical under Action of Gravity Field with between surface level.
Further, described index dial and pointers outside are covered with transparent protective shield.
The beneficial effects of the utility model are:
The utility model, by changing the shape of traditional surveyor's staff, is set to annular, does not need in use always adjusting angle, only need to be placed on ground to be measured.
Brief description of the drawings
Below in conjunction with accompanying drawing, annular surveyor's staff of the present utility model is described further.
Fig. 1 is the structural representation of annular surveyor's staff in embodiment.
Fig. 2 is the schematic cross-section of annular vacuole pipe.
Embodiment
Embodiment
Shown in Fig. 1 and Fig. 2, annular surveyor's staff in the utility model, comprise surveyor's staff pedestal 1 and be arranged on the annular vacuole pipe 2 on surveyor's staff pedestal 1, the cross section of annular vacuole pipe 2 is circular, in annular vacuole pipe, be filled with horizontal indicator solution, in the time of annular vacuole pipe 2 level, horizontal indicator solution 3 just covers the bottom of annular vacuole pipe 2.
In order further directly to read the angle between being tested surface and surface level, the side of surveyor's staff is provided with index dial 4, and the center of index dial 4 is provided with tuning drive gear 5 by rotating shaft, and pointer 5 keeps vertical under Action of Gravity Field with between surface level.
Index dial 4 and pointer 5 outsides are covered with transparent protective shield.
The above-described embodiment that is not limited to of the present utility model, all employings are equal to replaces the technical scheme forming, and all drops in the protection domain of the utility model requirement.
