Abstract
A kind of Novel set square, the set square are equipped with protractor, and the protractor includes corresponding angle index line；Angle index line along the protractor is equipped with closed arc-shaped cavity, and the closed arc-shaped cavity constitutes the semicircular ring of fixed curvature；Liquid, bubble are equipped in the cavity, it is characterised in that: be additionally provided with bead in the arc-shaped cavity；Its diameter is less than the circular cross section diameter of closed arc-shaped cavity, and can sink in the liquid in closed cavity.The bead is a spherical solid.The bead is made of a kind of drop constituted insoluble in the solution for filling liquid in closed cavity, the drop the solution that density is greater than the fluid density filled in closed cavity.
Description
Technical field
A kind of Novel set square belongs to measuring tool field.
Background technique
The protractor having on current set square cannot make horizontal line and vertical line on blackboard, can not detect flat
Whether face is horizontal (such as whether desktop is horizontal).In order to preferably make horizontal line, vertical line, relative to vertical line and horizontal line
The line of certain angle, someone devise one ball of placement in annular cavity.But ball can swing in measurement,
Need the regular hour that can just stop.And it cannot judge whether horizontal similar to ground, desktop.In order to overcome the above problem,
I, which designs, allows ball with damped motion, then ball will stop quickly, convenient for users to fast and accurately reading.
The utility model has the advantages that angle can be indicated fast and accurately, the presence of the horizontal measurement function, bubble of set square is extended
It can measure such as ground, the isoplanar levelness of desktop.
Summary of the invention
A kind of Novel set square, the set square are equipped with protractor, and the protractor includes corresponding angle index line；
Angle index line along the protractor is equipped with closed arc-shaped cavity, and the closed arc-shaped cavity constitutes the semicircle of fixed curvature
Ring；Liquid, bubble are equipped in the cavity, it is characterised in that: be additionally provided with bead in the arc-shaped cavity；Its diameter is less than closed
The circular cross section diameter of arc-shaped cavity, and can sink in the liquid in closed cavity.
The bead is a spherical solid, and the circular cross-section that the diameter of the spherical solid is less than closed arc-shaped cavity is straight
Diameter, the spherical solid can sink in the liquid in closed cavity.
The bead is by a kind of drop constituted insoluble in the solution for filling liquid in closed cavity, and the drop is by close
The solution that degree is greater than the fluid density filled in closed cavity is constituted.
The interior cross section of the closed arc-shaped cavity is circle.
The external cross section of the closed arc-shaped cavity is circle.
The external cross section of the closed arc-shaped cavity is triangle, rectangle.
Low freezing point, not volatile liquid are filled in the closed arc-shaped cavity.
The set square is equipped with hand-held device.
The set square plane is equipped with magnet.
Detailed description of the invention
Fig. 1: Novel set square bevel edge is in horizontality figure.
Fig. 2: Novel set square bevel edge is in state diagram on horizontal plane, described horizontal plane such as desktop, ground etc..
Attached drawing main composition: 1-bubble, 2-protractor angular centres, 3-hand-held devices, 4 closed arc-shaped cavities, 5-
Bead.
Specific embodiment
A kind of Novel set square, the set square are equipped with protractor, and the protractor includes corresponding angle index line；
Angle index line along the protractor is equipped with closed arc-shaped cavity, and the closed arc-shaped cavity constitutes the semicircle of fixed curvature
Ring；Liquid, bubble are equipped in the cavity, it is characterised in that: be additionally provided with bead in the arc-shaped cavity.
The bead is a spherical solid, and the circular cross-section that the diameter of the spherical solid is less than closed arc-shaped cavity is straight
Diameter, the spherical solid can sink in the liquid in closed cavity.The bead is not dissolved in closed cavity by one kind and is filled out
The drop that the solution of filling liquid body is constituted, the drop are greater than the solution structure for the fluid density filled in closed cavity by density
At.
The interior cross section of the closed arc-shaped cavity is circle.The external cross section of the closed arc-shaped cavity is circle.Institute
The external cross section for stating closed arc-shaped cavity is triangle.Low freezing point, not volatile liquid are filled in the closed arc-shaped cavity
Body.The set square is equipped with hand-held device.The set square plane is equipped with magnet.
