Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in figures 1-8, the embodiment of the present invention provides a kind of mapping compasses, including hinge member 1, hinge member 1, by
The top plate of one rectangle and two semicircular side plates compositions, two side plates are symmetricly set on the front and back of top plate bottom,
The inside of hinge member 1 is in hollow shape, and the bottom of hinge member 1 is opening-like, and the bottom of hinge member 1 is provided with first
Stabilizer blade 2, the pointed setting in bottom end of the first stabilizer blade 2, and the second stabilizer blade 3 is hinged on hinge member 1, the second stabilizer blade 3
Paintbrush 4 is connected on free end, the top of the first stabilizer blade 2 is fixedly connected with the bottom of two side plates, the second stabilizer blade 3 then articulated shaft two
Between a side plate.The side of first stabilizer blade 2 is provided with slot structure compatible with the second stabilizer blade 3.Second stabilizer blade 3 is far from hinge bar
5 one end is made of two arc-shaped clamping units 17.And the front of hinge member 1 is provided with the scale of arc, carves
The angle of degree is identical as the central angle of two 7 stabilizer blades of the gear teeth, and the second stabilizer blade 3 is in the rotation, it can be determined that goes out the second stabilizer blade 3
The distance of rotation.Specifically, setting the quantity of the gear teeth 7 as X, then the misalignment angle of two stabilizer blades is X/360.If two stabilizer blades are long
Degree is respectively a and b, can be obtained according to the cosine law when the second stabilizer blade 3 is rotated, often by between two adjacent latches
When, the bottom end of the second stabilizer blade 3 and the increased length in bottom end of the first stabilizer blade 2 areAnd set picture
The card of pen 4 contacts and makees then be obtained according to Pythagorean theorem at a distance from drawing for C.The bottom of the bottom end of paintbrush 4 and the first stabilizer blade 2
The distance at endDesigner can according to need at the first time just when mapping
It can obtain the circle either circular arc of desired radius size.
The inside of hinge member 1 is arranged in hinge bar 5, and opposite face of the both ends of hinge bar 5 respectively with two blocks of side plates is fixed
It connects, is socketed with rotatable disc structure 6 on the outer surface of hinge bar 5, the outer surface of disc structure 6 is provided with the gear teeth 7, hinge
The inner wall front of relay part 1 is provided with race 8 compatible with the gear teeth 7, and race 8 is that a centre is round, and circular
Edge is in the slot structure of dentation setting.Under normal circumstances, disc structure 6 is located at the inside of circular trough, and the gear teeth 7 are located at dentation
The inside of slot.The gear teeth 7 are trigone wimble structure, and the back side of the gear teeth 7 is triangle projective planum, and the front of the gear teeth 7 is that two differences are flat
The triangle in face.Since central angle degree of the angle not necessarily between two gear teeth of the second stabilizer blade 3 rotated every time is equal
Either its integral multiple, therefore the gear teeth 7 are arranged to special trigone wimble structure, the gear teeth can be made in the first spring 10 in this way
Under the action of pressure, so that the gear teeth 7 is shifted and successfully snap onto the inside of race 8, this can generate certain error in the process,
But error can be less thanAccording to required accuracy, can be taken turns by changing
The quantity of tooth 7 is to change the accuracy of compasses.The back side of disc structure 6 is provided with the flanged structure 9 of circle protrusion, and second
One end of support foot 3 is fixed on the outer wall of flanged structure 9.
The first spring 10 is provided between the back side of disc structure 6 and the back side of hinge member 1, the first spring 10 is wrapped in
On hinge bar 5, the front of hinge member 1 is provided through button 11, and block 16, the block 16 and hinge are provided on button 11
The inner wall front face of relay part 1, one end that button 11 is inserted into hinge member 1 are inlaid with rotatable ball 18, pass through setting
Block be detached from button 11 will not with hinge member 1, and by be arranged ball 18 can reduce it is positive with disc structure 6
Frictional force reduces loss.One end of button 11 and the front face of disc structure 6, the back side of hinge member 1 is provided with sector
12, sector 12 is internally provided with arching trajectory 13, and the side of arching trajectory 13 is opening-like, and the inside of arching trajectory 13 is set
It is equipped with second spring 14, plectrum 15 is additionally provided on the outer surface of flanged structure 9, the free end of plectrum 15 passes through arching trajectory 13
Opening insertion arching trajectory 13 inside.
When in use, then the circle of picture required for obtaining one or the radius length Y of circular arc press lower button 11, when pressing
After lower button 11, button 11 will push disc structure 6 and be slided on hinge bar 5, and lean on to the back side of hinge member 1
Hold together, in the process, the gear teeth on disc structure 6 can be detached from the positive race 8 of 1 inner wall of hinge member, then, rotation second
Stabilizer blade 3, during rotating the second stabilizer blade 3, with Y divided by the bottom end of paintbrush 4 when often passing through a scale and the first stabilizer blade 2
(d carries out in order to facilitate designer using can first calculate, as each circle the distance between bottom end d after compasses complete
The standard parameter of rule carry out using).And in the rotation, disc structure 6 will drive plectrum 15 and be rotated, when plectrum 15
The second spring 14 inside arching trajectory 13 can be compressed when being rotated, the second elastic force 14 is made to store power, after rotation is completed, unclamped
Button 11, after release button 11, the elastic force that the first spring 10 restores will push disc structure 6 and be restored to original position, when
When disc structure 6 is restored to original position, the inside that the gear teeth 7 can snap onto race 8 can not be rotated, and just can be reached at this time
To the effect of compasses positioning, and paintbrush 4 is snapped into clamping unit 4 up, start to map, after mapping is completed, removed
Paintbrush 4 presses lower button 11 again, after pressing lower button 11 again, will push disc structure 6 and the gear teeth 7 and race 8 is detached from,
At this point, the elastic force that second spring 14 is restored will push plectrum 15 and be rotated, when plectrum 15 is rotated, disc structure can be made
6 are returned to initial position, and the second stabilizer blade 3 is caught in inside the slot structure of 2 side of the first stabilizer blade at this time.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
