Description
Technical field
The utility model belongs to survey instrument technical field, is a kind of solid angle measurement equipment in particular.
Background technology
At present, angle measuring instrument is more, but structure is all more complicated, use inconvenience, intuitively can not draw the angle of object being measured, when particularly measuring the inclination angle of inclined plane of downward-sloping object, not easy to operate, often affect the correctness of measurement data, simultaneously also inadaptable teaching application.
Summary of the invention
In order to solve the problem, the utility model provides one and is suitable for application of imparting knowledge to students, and intuitively can draw the angle of object being measured, measurement data is protractor accurately, its concrete scheme is: described protractor is by secondary dip stick, vertical level, graticule, angle scale, angle blaze, main dip stick, main scale blaze, rotating shaft, level vial, rotation mark post forms, it is characterized in that angle scale is set to semi-circular, main dip stick is set to ruler-type, the two ends of angle scale are connected with the two ends of main dip stick respectively, angle blaze is provided with inside the outward flange of angle scale, main scale blaze is provided with inside the outward flange of main dip stick, the inside middle portion of described main dip stick arranges rotating shaft, secondary dip stick is connected with rotating shaft by rotating mark post, and can rotate around the shaft, the middle part of described rotation mark post is provided with graticule along rotating mark post longitudinal axis.
Main dip stick described in the utility model, is characterized in that the middle part of main dip stick is provided with level vial, utilizes level vial main dip stick can be adjusted to horizontality, and then utilizes graticule and angle scale can survey reading tested angle numerical value.
Secondary dip stick described in the utility model, is characterized in that the middle part of secondary dip stick is provided with vertical level, utilizes vertical level secondary dip stick can be adjusted to horizontality, and then utilizes graticule and angle scale can survey reading tested angle numerical value.
The beneficial effects of the utility model are that described protractor is suitable for application of imparting knowledge to students, and intuitively can draw the angle of object being measured, and measurement data is accurate.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model; In accompanying drawing 1:
1. secondary dip stick, 2. vertical level, 3. graticule, 4. angle scale, 5. angle blaze, 6. main dip stick, 7. main scale blaze, 8. rotating shaft, 9. level vial, 10. rotate mark post.
Embodiment
1 pair of the utility model describes in further detail by reference to the accompanying drawings, so that the public grasps implementation method of the present utility model better, the utility model specific embodiment is: described protractor is by secondary dip stick 1, vertical level 2, graticule 3, angle scale 4, angle blaze 5, main dip stick 6, main scale blaze 7, rotating shaft 8, level vial 9, rotate mark post 10 to form, it is characterized in that angle scale 4 is set to semi-circular, main dip stick 6 is set to ruler-type, the two ends of angle scale 4 are connected with the two ends of main dip stick 6 respectively, angle blaze 5 is provided with inside the outward flange of angle scale 4, main scale blaze 7 is provided with inside the outward flange of main dip stick 6, the inside middle portion of described main dip stick 6 arranges rotating shaft 8, secondary dip stick 1 is connected with rotating shaft 8 by rotating mark post 10, and can around the shaft 8 rotate, the middle part of described rotation mark post 10 is provided with graticule 3 along rotating mark post 10 longitudinal axis.
Main dip stick 6 described in the utility model, it is characterized in that the middle part of main dip stick 6 is provided with level vial 9, utilize level vial 9 main dip stick 6 can be adjusted to horizontality, and then utilize graticule 3 and angle scale 4 can survey reading tested angle numerical value.
Secondary dip stick 1 described in the utility model, it is characterized in that the middle part of secondary dip stick 1 is provided with vertical level 2, utilize vertical level 2 secondary dip stick 1 can be adjusted to horizontality, and then utilize graticule 3 and angle scale 4 enough surveys can read tested angle numerical value.
During use, utilize main dip stick 6 to measure the angle of acclivitous object plane, utilize secondary dip stick 1 to measure the angle of downward-sloping object plane, simple to operate, easy to use.
The beneficial effects of the utility model are that described protractor is suitable for application of imparting knowledge to students, and intuitively can draw the angle of object being measured, and measurement data is accurate.
