Abstract
One kind, which can position, prints off center of circle white board compasses, and by fixed bearing, aperture disk magnet, soft a surname film ring constitutes center of circle positioning component, draw bowlder center of circle positioning gauge bar set pen circle can two gauge bars rotation in surface and ensure that drawing round stability and guarantee draws positive round.Free ink pen passes through center of circle positioning component and is accurately imprinted in the center of circle on blank, aperture disk magnet and blank iron layer strength are attracting, center of circle positioning component by preventing compasses from walking cunning in the soft broad film increase damping being attached on blank, make center of circle positioning gauge bar can exact residence at target center location.
Description
Technical field
It is a kind of to position the white board compasses for printing off the center of circle, it is related to the description of the circle on the irony blank of the occasions such as teaching, it is special
It is not the system of retouching that need to accurately print off the circle in the center of circle.
Background technique
The blank majority category irony bottom plate of the occasions such as teaching, outer oil, which is painted, constitutes writing layer by one layer of white matter material, because
This, blank can attract each other with magnetic material.Majority setting circle by the way of sucker when retouching rounding on the blank
The heart holds center of circle foot drawing bowlder, although easy to operate in this way, can not accurately print off the center of circle, sometimes it also occur that center of circle foot
Sliding situation is walked, is unfavorable for guaranteeing what a circle one-time-reach-place draws.The white board compasses there are aiming at the problem that, the present invention can overcome
Described problem, using bearing, disk aperture magnet and the thin glue for reinforcing frictional force, it is fixed that the objects such as special free ink pen constitute white board compasses
Position foot, draws circular arc, and the center of circle can be accurately positioned and the center of circle is imprinted on blank reliablely.
Summary of the invention
It is a kind of to position the white board compasses for printing off the center of circle, it is made of picture arc gauge bar 9 and center of circle positioning gauge bar 8, draws arc gauge bar 9
Intersect hinge with center of circle positioning 8 Mr. Yu one end of gauge bar, the two other end respectively has functional structure by oneself.Draw the other end of arc gauge bar 9
Equipped with set pen circle 11, free ink pen 10 is extended there through, set pen circle 11 is provided with regulation cock, and to fasten free ink pen 10, set pen circle 11 is horizontal
Section and picture arc gauge bar 9 are in 120 degree of relationships.The set pen circle 6 and center of circle positioning gauge bar 8 that the center of circle positions 8 other end of gauge bar are by hinged
Part 7 connects, and the set pen circle 6 can only be in a rotation in surface for drawing arc gauge bar 9 and center of circle positioning rule 8 bars composition；Described
It covers pen circle 6 and passes through free ink pen 5, free ink pen 5 is fastened by the regulation cock of set pen circle 6；5 head of free ink pen is securely inserted into fixed
Hyte part 12；For the positioning component by fixed bearing 1, annulus partition 2, intermediate aperture disk magnet 3, soft thin film ring 4 is same
Axis fitting is bonded；Fixed bearing 1 tightly entangles the written top of free ink pen 5, and 2 internal diameter of annulus partition is greater than free ink pen 5
Any outer diameter plays a part of separating and turn-take in fixed bearing 1 and intermediate aperture disk magnet 3, guarantees free ink pen 5 and determine pen
Turn-taking in bearing 1 can flexible rotating；Soft thin film ring 4 plays a part of to greatly increase frictional force, ensures picture bowlder center of circle positioning rule
Bar 8 does not walk cunning on blank, and 5 pen tip of free ink pen has elastic telescopic function, after 5 pen tip of free ink pen is inserted in positioning component 12, phase
It is slightly 1 millimeter prominent to soft thin film 4.
Detailed description of the invention:
Fig. 1: one kind, which can position, prints off the white board compasses structure in the center of circle and illustrates front view, and the representative component names of each label are such as
Under:
Fixed bearing 1
Annulus partition 2
Intermediate aperture disk magnet 3
Soft thin film ring 4
Free ink pen 5
Cover pen circle 6
Articulation piece 7
The center of circle positions gauge bar 8
Draw arc gauge bar 9
Free ink pen 10
Cover pen circle 11
Positioning component 12
Fig. 2: one kind can position 12 top view of white board compasses positioning component for printing off the center of circle, and the representative component names of each label are such as
Under:
Fixed bearing 1
Annulus partition 2
Intermediate aperture disk magnet 3
Soft thin film ring 4
Embodiment: the compasses are opened by radius demand, the center of circle position the positioning component 12 of gauge bar 8 first blank, it is intermediate
3 strong adsorption blank lining iron layer of aperture disk magnet, since pressure effect 5 pen tip of free ink pen inside contracts, pen tip presses blank,
Centre point is printed off, rotation picture arc gauge bar 9 draws circle, since suction is big, in addition soft thin film ring 4 increases frictional force, draws circle process
Middle center of circle positioning gauge bar 8 will not walk cunning.
Claims (1)
1. one kind can position the white board compasses for printing off the center of circle, it is made of picture arc gauge bar 9 and center of circle positioning gauge bar 8, draws 9 He of arc gauge bar
The center of circle positions 8 Mr. Yu one end of gauge bar and intersects hinge, and the two other end respectively has functional structure by oneself；The other end for drawing arc gauge bar 9 is set
