Description
Technical Field
The utility model relates to a geological compass correcting unit.
Background
Before the geological compass is used, the declination of the geological compass must be corrected according to the area, and the azimuth angle of the target object is measured during correction. When in measurement, the brake screw is loosened to enable the object target plate to point to the object to be measured, even if the north end of the compass points to the object and the south end of the compass is leaned against the object to be measured, the object target plate small hole, the thin wire on the cover glass, the object target plate small hole and the like are connected on a straight line, meanwhile, the water bubble of the chassis water level is centered, the degree pointed by the north pointer when the magnetic pointer is static is the azimuth angle of the object to be measured, the brake screw is loosened by the existing tool in the hand, and sometimes the existing tool in the hand can influence the correction of the geological compass.
Disclosure of Invention
The utility model aims at solving the relaxation of present address compass when rectifying that the brake screw needs solitary instrument to go on, can influence its problem of rectifying when not carrying the instrument, provide a self and carry the geology compass correcting unit that the brake screw loosens the instrument.
The above purpose is realized by the following technical scheme:
a geological compass correcting device, comprising: the compass comprises a compass body and a brake screw arranged on the compass body, wherein a fixed shaft is connected with one end of an arc rotating arm in a groove of the compass body, the other end of the arc rotating arm is connected with a sleeve through a connecting shaft, a screw arbor is arranged in the sleeve, and blocking pieces are arranged on two sides of the screw arbor.
The geological compass correcting device is characterized in that a slot is formed in the right side face of the groove.
The geological compass correcting device is characterized in that the upper part of the circular arc rotating arm is provided with a notch.
The geological compass correcting device is characterized in that the width of the groove is larger than that of the circular arc rotating arm, and the width of the circular arc rotating arm is larger than the outer diameter of the sleeve.
The utility model discloses the beneficial effect who reaches is:
1. the utility model discloses need not additionally carry the brake screw and loosen the instrument, just can carry out loosening of brake screw at any time through the screwdriver pole, carry out the correction of geological compass at any time, can not influence the efficiency of its correction.
2. The utility model discloses circular arc rotor arm is back in rotating the recess, and circular arc rotor arm, sleeve pipe and screwdriver pole all are located the recess, can not influence the subsequent correction work of geological compass behind the loosening brake screw.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:
FIG. 1 is a schematic structural view of the brake screw of the present invention when loosened;
FIG. 2 is a schematic structural view of the brake screw of the present invention after being loosened;
FIG. 3 is a schematic structural view of a circular arc rotating arm;
in the figure: 1. a compass cover; 2. a fixed shaft; 3. a circular arc rotating arm; 4. a connecting shaft; 5. a sleeve; 6. a screwdriver rod; 7. a groove; 8. a slot; 9. a compass body; 11. A baffle plate; 12. opening the gap; 13. and (5) stopping screws.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Example 1:
a geological compass correcting device, comprising: compass body 9 is in with the setting compass body on the brake screw 13, compass body and compass lid 1 are articulated, recess 7 of compass body in pass through fixed axle 2 with the one end of circular arc rotor arm 3 and be connected for the circular arc rotor arm can use the fixed axle to rotate as the center, the other end of circular arc rotor arm and sleeve pipe 5 pass through connecting axle 4 and be connected, make the sleeve pipe can use the connecting axle to rotate as the center, the intraductal screw arbor 6 that is provided with of sleeve, the screw arbor can be at the intraductal activity of cover, including horizontal slip and rotation, the both sides of screw arbor have separation blade 11, the separation blade plays spacing effect to the position removal of screw arbor, the screw arbor is a style of calligraphy screw arbor.
Example 2:
the geological compass correcting device of embodiment 1, wherein the right side of the groove is provided with a slot 8.
Example 3:
the geological compass correcting device of embodiment 1 or 2, wherein the arc rotating arm is provided with a notch 12 at the upper part.
Example 4:
the geological compass correction device of embodiment 1 or 2 or 3, wherein the width of the groove is greater than the width of the arc rotor arm, and the width of the arc rotor arm is greater than the outer diameter of the casing.
When geological compass does not need to be rectified, the right-hand member of screwdriver pole is inserted in the slot, when needing geological compass to rectify, slip screwdriver pole slides left, make screwdriver pole's right-hand member break away from with the slot, then rotate the circular arc rotor arm, later the sleeve pipe rotates again, then slip screwdriver pole makes on the screwdriver pole inserts the brake screw loosen the brake screw, loosen the back at the brake screw again with circular arc rotor arm antiport, the sleeve pipe rotates, insert the right-hand member of screwdriver pole in the slot, at this moment the circular arc rotor arm, sleeve pipe and screwdriver pole all are located the recess, can not influence geological compass subsequent rectification work.
Claims (4)
