Description
Technical field
The present invention relates to technical field of stationery, and in particular to the side of a kind of ghost line double-purpose compasses and drafting broken circle
Method.
Background technology
In the teaching and study of the courses such as mechanical drawing, it is often necessary to which the line that stippled on blackboard is justified or broken circle, one
As educational compasses can not directly stipple line circle or broken circle, can only first draw a dot and then draw a bit of circular arc, Ran Houzai
Dotted line circle or broken circle are repeatedly drawn intermittently, or first draws a solid line circle and wiped every a bit of again, also
There is no a kind of educational compasses better to solve this problem.
Applying date 2014.11.04, the patent of application number 201410659708.8 discloses a kind of dotted line educational compasses,
It is main to be made up of handle, rotation pin, enhanced bent piece, screw I, picture round seat assembly, screw II and center of circle pin.The picture round seat assembly
Mainly it is made up of main shaft, round nut, spring, housing, axle I, road wheel, bearing, axle II, cam, unilateral bearing and elastic nut.
Present inventive concept is ingenious, rational in infrastructure, easy to operate, can both draw solid line circle, it is also possible to which the line that stipples is justified or broken circle.
But there is problems with above-mentioned patent：First, said apparatus realize the upper and lower past of main shaft for one week by cam rotation
Multiple motion, and then realize contact of the main shaft with blackboard and depart from, therefore its broken circle for drawing, the dotted line of its circular arc and solid line
Ratio cannot be adjusted；2nd, moved back and forth every time due to main shaft and all touched with blackboard, easily chalk tip is touched it is disconnected, or by powder
Pen is upwardly.
The content of the invention
In order to solve technical problem present in background technology, the present invention provides a kind of ghost line double-purpose compasses, passes through
Chalk quantity in regulation cross pen container carrys out the ghost line ratio of dotted line circular arc；Reciprocal fortune can also be replaced using rotating manner
Flowing mode, adjusts contact of the chalk with blackboard and separates, it is to avoid chalk clashes into and is broken with blackboard；The present invention also provides a kind of base
In the method that above-mentioned ghost line double-purpose compasses draw broken circle.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of ghost line double-purpose compasses, including handle, it is described also including the center of circle pin, the line pin that are hinged on handle
Line pin end is hinged with switch；
The switch includes：
Shell, the hollow rectangle body of lower ending opening, upper end is hinged by lug with holes with line pin, and outside rear is provided with behaviour
Make circular hole；
Driving rolls, is rotatably located at the inner side front of the shell inner cavity；
Driver plate, is located at the driving rolls lateral surface with one heart, and the driver plate side is provided with breach, the driving rolls outside
Face is additionally provided with drive pin with the breach corresponding position；
Sheave, is rotatably located at the shell inner cavity rear, is circumferentially evenly equipped with four drivings be radially arranged and described
The radial slot that pin coordinates, forms the locking groove coordinated with the driver plate arc outer wall locking between adjacent radial groove；
Cross pen container, is located at the sheave lateral surface, and four ends of the cross pen container are respectively equipped with to be installed with chalk
Jack, four ends of the cross pen container are alignd the midpoint of locking groove, four ends of cross pen container outside respectively
It is bolted with to fix the first bolt of chalk respectively, first bolt extends to housing exterior through the operation circular hole；
Fixed pen container, is located at the case nose, and lower end is provided with to be installed with the jack of chalk, the fixed pen container outside
Lower end is provided with to fix the second bolt of chalk, and second bolt extends housing exterior through shell.
Further, the driving rolls includes outer ring, inner ring, and the outer ring inwall is interior narrow outer taper wide, described
Inner ring is bolted to shell inner side front by the 3rd, and ball is circumferentially evenly equipped between the outer ring, inner ring.
A kind of method that broken circle is drawn based on above-mentioned ghost line double-purpose compasses, it is characterised in that：Comprise the following steps：
Step 1, takes the ghost line double-purpose compasses；
Step 2, adjusts cross pen container：
Step 2.1, adjusts cross pen container attitude：
The driving rolls is stirred with hand to rotate, drive the driver plate to rotate；
The driver plate is often rotated one week, is driven the sheave, the cross pen container to rotate and a quarter and then is stalled four
The intermittent rotary of/tri- weeks：
The drive pin insertion radial slot is interior and drives the sheave to rotate quadrant；
The drive pin is skidded off from radial slot, and at the same time the extrados of the driver plate is transferred in the locking groove
By the sheave locking, now the either end of cross pen container leans out downwards；
Step 2.2, installs chalk：
Corresponding first bolt in end that cross pen container is leant out downwards is unscrewed, and chalk then is inserted into cross from lower to upper
The end that pen container leans out downwards, adjustment chalk position causes that its lower end, less than the driving rolls minimum point 1mm-5mm, then will
Corresponding first bolt is screwed, and chalk is fixed；
Chalk is installed at least one end in four ends of the cross pen container；
Step 3, the fixed pen container of adjustment：
Second bolt is unscrewed, chalk is inserted into the fixed pen container from lower to upper, adjustment chalk position does not have its whole
Enter in fixed pen container；
Step 4, draws broken circle：
The center of circle pin is fixed on blackboard, then hand pinches the handle, drives the line pin stopping around center of circle pin
End moves in a circle；
The driving rolls drives the driver plate to move in a circle, and drives the sheave to rotate and a quarter and then stalls
The intermittent rotary of 3/4ths weeks；
When one end that the cross pen container installs chalk leans out downwards, chalk is contacted with blackboard, and with the rotation of line pin
Circular arc is drawn on blackboard；
When one end that cross pen container installs chalk inclines because of rotation or cross pen container do not install one end of chalk to
Under when leaning out, it is impossible to draw circular arc；
Rotate the line pin one week, draw a broken circle.
Beneficial effects of the present invention：
First, the ghost line double-purpose compasses are by adjusting the chalk quantity in cross pen container come the dotted line reality of dotted line circular arc
Line ratio：
The surrounding i.e. sheave intermittent rotary one week is continuously rotated as a cycle with the driving rolls, in the cycle
It is interior：
When only one of which end is provided with chalk in the cross pen container, just in blackboard when only the chalk is contacted with blackboard
Upper drafting circular arc, other are not provided with the end of chalk to test when the chalk is inclined because of rotation, or on cross pen container
Circular arc is not drawn when going out, solid line occupies very little ratio in the dotted line circular arc now drawn.
When there is two adjacent or relative ends to be provided with chalk in the cross pen container, solid line is occupied in dotted line circular arc
Ratio increase；
When there is three ends to be provided with chalk in the cross pen container, the ratio that solid line is occupied in dotted line circular arc further increases
Greatly；
When there is four ends to be provided with chalk in the cross pen container, the ratio that solid line is occupied in dotted line circular arc is maximum：When
Keep down holding position of leaning out of any chalk is to draw circular arc, and circular arc is not drawn when any chalk is inclined because of rotation.
2nd, the ghost line double-purpose compasses replace reciprocating manner, regulation chalk and blackboard using rotating manner
Contact and separate, it is to avoid chalk clashes into and is broken with blackboard.
