Problems solved by technology

[0002] At present, the instruments commonly used in building construction to measure slope and angle are complicated and inconvenient to operate, and the accuracy is difficult to guarantee
When looking for the slope of the roof of the building construction, it is very inconvenient to operate with the existing measuring instruments because it is working at high altitude and the area is not large; The slope is small, the operating range is limited, the existing precision measuring instruments are limited in operation, and the measurement tasks cannot be accurately completed, and the simple measuring instruments are difficult to meet the measurement requirements

Embodiment Construction

[0011] The present invention will be described in detail below with reference to the accompanying drawings.

[0012] The present invention is made up of worm screw 1, worm wheel 2, manual knob 3, primary dial 4, level ruler 5, level bubble 6, leaning chi 7, secondary dial 8, vernier dial 9.

[0013] As shown in the figure, the worm 1 is a single-headed worm, the worm 1 is rigidly connected to the manual knob 3, the worm wheel 2 is rigidly connected to the level 5, the entire circumference of the worm wheel 2 has 60 teeth, and the upper and lower sides of the level are respectively equipped with horizontal levels The bubble 6 and the ruler 7 are respectively hinged with the worm screw 1 and the worm wheel 2. The cylindrical surface at the lower left of the level ruler 5 is used as a half-circle worm gear tooth. The worm 1 and worm gear 2 are driven by worm gears. The primary dial 4 is parallel and concentric with the end face of the worm gear 2 and is fixed on the scale 7. The ...

Abstract

The invention relates to grade angle measuring apparatus which belongs to measuring apparatus. It is made up of worm, worm wheel, manual knob, once dial, level bar, level bench-mark bubble, guiding rule, secondary dial, and vernier dial. The worm is fixedly connected to the manual knob. The worm wheel is fixedly connected to the level bar. The guiding rule is hinged on worm and worm wheel. The once and secondary dials are fixed on the guiding rule. The manual knob is set vernier dial. It can be used to exactly measure grade and angel in building engineering. And it has the advantage of simple structure, small size, high precision, and little measuring error which is not bigger than one in a thousand degrees.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a slope and angle measuring instrument. Background technique [0002] At present, the instruments commonly used in building construction to measure slope and angle are complicated and inconvenient to operate, and the accuracy is difficult to guarantee. When looking for the slope of the roof of the building construction, it is very inconvenient to operate with the existing measuring instruments because it is working at high altitude and the area is not large; The slope is small, the operating range is limited, the operation of the existing precision measuring instruments is limited, and the measurement tasks cannot be accurately completed, and the simple measuring instruments are difficult to meet the measurement requirements. Contents of the invention [0003] The object of the present invention is to provide a slope and angle measuring instrument which is flexible and convenient to u...
