Disk, dumb card are fixed with the cylindrical outer box on Tianchi, and the various contents on compass are stamped on the different coils of dumb card；Outward
Disk is generally circular in shape, and is constituted ten road of right overhead i.e. position line through outer disk periphery and with crystal line of the outer disk circle center hole in right-angled intersection
For reading the content in inner disc card.The shell for folding compass is usually to be flexibly connected by hinge with upper lid by base, and
The outer disk of compass is affixed in base, and the outer end of upper lid is provided with sight, and the outer end of base is provided with foresight, sight, orientation
Line and foresight point-blank, fully open the sight on rear casing in Shang Gai and foresight coordinate rhumb line preferably can take aim at
Quasi- subject matter, while the shell for folding compass also allows for the carrying in field.
But presently used folding compass is that Tianchi is directly embedded in outer disk, first pass through during using folding compass
Rotate inner disc and Tianchi again to adjust to needle and seabed after position line and foresight in compass outer disk and sight alignment subject matter
Line overlaps, and content of stamping on the inner disc occurred under position line when needle is overlapped with submarine cable on same level position is to need
Data to be measured, that is to say, that now then can determine the subject matter orientation number of degrees according to the position line above dumb card.Measurement
Repetition above-mentioned same step is still needed during next subject matter, is first directed at subject matter and is adjusted reading after needle and submarine cable again
According to, rather than just can directly read data after being directed at subject matter, it is this different subject matters are required to readjust needle with
The measuring process that submarine cable overlaps not only brings certain difficulty to beginner, also causes temporal wave to commonly used person
Take.
Utility model content

Fixed, outer disk is rounded, through outer disk periphery and is constituted ten road of right overhead with crystal line of the outer disk circle center hole in right-angled intersection and is positioned
Line, is provided with the groove for installing Tianchi in the middle part of outer disk；The compass that folds is included by the base and upper lid of hinge flexible connection
The shell of composition, the outer end of upper lid are provided with sight, and the middle part in upper lid is provided with spirit level, and the outer end of base is provided with
A plastic bearing is provided between the cylindrical outer box of foresight, the groove of the outer disk and Tianchi, and plastic bearing includes inner ring
And outer ring, in the groove of the embedded Tianchi in outer ring of plastic bearing, the inner ring of plastic bearing is bonding with the cylindrical outer box of Tianchi solid
Fixed, inner disc is adhesively fixed with the inner ring upper end of plastic bearing；The middle part of the outer disk is provided with circular port one, circular port one
Diameter less than plastic bearing race diameter；It is provided with the middle part of the base and one an equal amount of circular port of circular port
Two, base is fixedly connected with outer disk.
The diameter of the circular port one is equal to the diameter of the cylindrical outer box of Tianchi.
Fixed seat is provided with immediately below the Tianchi.
The fixed seat lower end of the Tianchi is provided with fixed bolt hole.
The utility model beneficial effect is：The folding compass structure that is automatically positioned of the present utility model is simple, easy to use；By
It is flexibly connected by plastic bearing between the Tianchi and outer disk for folding compass, after adjusting needle and submarine cable, fixes Tianchi
Needle need not be readjusted to each subject matter of later measurement then just can be according to position line on inner disc with submarine cable
Position directly reads data, and eliminating carries out needle and submarine cable integration steps and can utilize and rotate outer for each subject matter
Position line alignment subject matter on disk just can directly read data, not only simplify step, saved the time, and also allow for just
Scholar grasps.
Below in conjunction with the accompanying drawings the folding compass that is automatically positioned of the present utility model is described further.
