Abstract
This utility model relates to the combined measuring tool of a kind of protractor and ruler, a kind of protractor and the combined measuring tool of ruler, it is characterised in that include ruler and protractor；Described ruler length is more than the radius of protractor；It is provided with on described protractor and the projection of protractor concentric；Described ruler one end is provided with the groove with male cooperation；Described ruler coordinates with protractor angle index line to be in and is perpendicular in ruler cross-sectional direction be provided with and protractor concentric and isometrical circular arc.This combined measuring tool of this combined measuring tool can realize both the easiest combining, and can accurately draw the straight line of certain angle and length, also is able to be used separately simultaneously, improves the range of ruler and protractor.
Description
Technical field
This utility model relates to a kind of schooling apparatus, and protractor and ruler can be combined and realize more multi-functional measurer by one, particularly relates to the combined measuring tool of a kind of protractor and ruler.
Background technology
Currently used protractor and ruler be all ruler for setting-out, protractor for measuring angle, or can not be applied in combination each other use more complicated.The combined measuring tool of this protractor and ruler by both the easiest combining, and can accurately draw the straight line of certain angle and length.
Can only be used separately to solve existing protractor and ruler, in the case of needs picture with the center of circle longer straight line of distance, alone protractor cannot realize accurately, thus the combined measuring tool of a kind of protractor and ruler is proposed, this combined measuring tool by both the easiest combining, and can accurately draw the straight line of certain angle and length.
Utility model content
This utility model can only be used separately to solve existing protractor and ruler, in the case of needs picture with the center of circle longer straight line of distance, alone protractor cannot realize accurately, thus the combined measuring tool of a kind of protractor and ruler is proposed, this combined measuring tool by both the easiest combining, and can accurately draw the straight line of certain angle and length.
This utility model is achieved by the following technical solution:
A kind of protractor and the combined measuring tool of ruler, it is characterised in that include ruler and protractor；Described ruler length is more than the radius of protractor；It is provided with on described protractor and the projection of protractor concentric；Described ruler one end is provided with the groove with male cooperation；Described ruler coordinates with protractor angle index line to be in and is perpendicular in ruler cross-sectional direction be provided with and protractor concentric and isometrical circular arc.
Further, the part of ruler overhang hornwork is provided with scale.
Further, described projection is semicircle or circular.
Further, described ruler and protractor abutting end are sector structure.
Further, the thickness of the part that described ruler horizontally outward extends is equal with protractor thickness.
Accompanying drawing explanation
Accompanying drawing 1 is the combined measuring tool schematic diagram of a kind of protractor and ruler；
Accompanying drawing 2 be a kind of protractor and ruler combined measuring tool in the structural representation of ruler；
Accompanying drawing 3 be a kind of protractor and ruler combined measuring tool in the structural representation of protractor.
Reference is as follows:
1-ruler；2-protractor；3-scale；4-circular arc；5-groove；6-is protruding.
Beneficial effect:
1. this combined measuring tool can realize both the easiest combining, and can accurately draw the straight line of certain angle and length.
2. this combined measuring tool also is able to be used separately simultaneously, improves the range of ruler and protractor.
3. the thickness of the part that ruler horizontally outward extends is equal with protractor thickness, can preferably ensure accuracy and the accuracy of line.
4. projection is provided in round, can make protruding and groove preferably with the use of.
5. it is provided with scale in the part that ruler horizontally outward extends, ruler combined measuring tool can be made also to have use value after being used separately.
Detailed description of the invention
A kind of protractor and the combined measuring tool of ruler, including ruler 1 and protractor 2；It is provided with on described protractor 2 and the projection 6 of protractor 2 concentric；Described ruler 1 one end is provided with and protruding 6 grooves 5 coordinated；Described ruler 1 coordinates with protractor 2 angle index line to be in and is perpendicular in ruler 1 cross-sectional direction be provided with and protractor 2 concentric and isometrical circular arc 4.
Wherein, the part of described ruler 1 overhang hornwork 2 is provided with scale 3.
Described protruding 6 is circular.
Described ruler 1 is sector structure with protractor 2 abutting end.
The thickness of the part that described ruler 1 horizontally outward extends is equal with protractor 2 thickness.
Work process:
By the protruding set of the groove of ruler 1 and protractor 2 and together with, then rotary ruler combination 1 i.e. can get the angle of protractor 2, rules along ruler 1.
Described embodiment be of the present utility model preferred embodiment; but the present invention is not limited to above-mentioned embodiment; in the case of without departing substantially from the flesh and blood of the present invention, any conspicuously improved, replacement or modification that those skilled in the art can make belong to protection scope of the present invention.
