Fig. 5 is a schematic diagram showing connection between a ranging host and a connection ball of a ranging apparatus with an adjustment base according to the present invention.
As shown in fig. 5, in some examples, the connection ball 13 may be made of a magnetically attractable metal material, and the connection ball 13 may be disposed at the ranging main body 12 in such a manner that the center of gravity of the ranging main body 12 is located at the center of the connection ball 13.

FIG. 3 is a schematic diagram showing a test host with a range unit with an adjustable base in accordance with the present invention; fig. 4 is a side view showing a test mainframe with a range finder with an adjustable base in accordance with the present invention.
As shown in fig. 3 and 4, in some examples, ranging host 12 may simultaneously emit ranging light and indication light of the same optical path as the ranging light by ranging lens 122. Because the light emitted by the absolute distance module is invisible measuring light, in the process of aligning the measuring light with the measured target ball, the measuring light cannot be directly found by human eyes and cannot be directly aligned with the measured target ball by human eyes, so that the indicating light module emits visible indicating light which is collinear with the measuring light, and when the measured target ball is aligned, the indicating light can be aligned with the measured target ball, namely the measuring light emitted by the absolute distance module is considered to be aligned with the measured target ball, and the aim of aligning the measuring light with the measured target ball is achieved.
In some examples, the ranging device 1 may also include a target ball for assisting in the measurement.
In some examples, the ranging device 1 may also include a signal display device 124 and a telescope 123 module. The signal display device 124 may be used to display the alignment of the measuring light and the target ball to be measured, and the greater the numerical value displayed by the signal display device 124, the better the alignment of the measuring light and the target ball to be measured, and the alignment of the measuring light and the target ball to be measured may be finely adjusted by the numerical value on the signal display device 124, so as to improve the alignment accuracy. When the measured distance is long, it is not easy for the human eye to observe whether the measuring light is aligned with the target ball, and therefore, it is necessary to observe the alignment by means of the telescope 123. When the measured distance is long, the human eye does not easily observe whether the measuring light is aligned with the target ball, and therefore, it is necessary to observe the alignment by means of the telescope 123, thereby improving the alignment efficiency.

In some examples, third rotating portion 1433 may include second fine adjustment screw 1406 and second return spring 1408 for adjusting second rotating portion 1432, second fine adjustment screw 1406 may be configured to push second rotating portion 1432 to rotate second rotating portion 1432 relative to third rotating portion 1433 about an axis of base 141 as a center of rotation to drive link mechanism 142 to rotate ranging host 12 in a second direction of rotation; the second return spring 1408 is configured to restore the rotational angle of the second rotational portion 1432 relative to the third rotational portion 1433.
In this case, the second fine adjustment screw 1406 and the second return spring 1408 adjust the relative rotation between the second rotating portion 1432 and the third rotating portion 1433 together, so as to convert the rotational redundancy into fine adjustment to ensure the horizontal posture of the ranging host 12 or the adjustment accuracy of the second direction, and improve the ranging accuracy of the ranging host 12.
In some examples, the first rotating portion 1431 may have a first protrusion (not identified in the figures), and the second fine adjustment screw 1406 and the second return spring 1408 may act together with the first protrusion (not identified in the figures) to move the first rotating portion 1431 coaxially with respect to the second rotating portion 1432. In this case, the second fine adjustment screw 1406 and the second return spring 1408 provided at the second rotating portion 1432 can reduce the influence on the coarse adjustment screw 1404 of the third rotating portion 1433, and the second fine adjustment screw 1406 and the second return spring 1408 act on the first protrusion (not shown) of the first rotating portion 1431 to convert the stroke of the screw of the second fine adjustment screw 1406 into the horizontal rotation of the first rotating portion 1431 and finely adjust the horizontal rotation of the first rotating portion 1431, thereby improving the distance measurement accuracy.
In some examples, the second return spring 1408 and the second fine adjustment screw 1406 are oppositely disposed and cooperate with a first protrusion (not identified in the figures) to translate the travel of the screw of the second fine adjustment screw 1406 into relative rotation of the first and second rotating portions 1431, 1432.
In other examples, a first protrusion (not identified in the figures) may be provided on the second rotating portion 1432, and the second return spring 1408 and the second fine adjustment screw 1406 may be provided on the first rotating portion 1431. In this case, the second fine adjustment screw 1406 and the second return spring 1408 provided at the first rotation part 1431 can reduce the influence on the coarse adjustment screw 1404 of the third rotation part 1433, and the second fine adjustment screw 1406 and the second return spring 1408 act on the first protrusion (not shown) of the second rotation part 1432 to convert the stroke of the screw of the second fine adjustment screw 1406 into the horizontal rotation of the first rotation part 1431 and finely adjust the horizontal rotation of the first rotation part 1431, thereby improving the distance measurement accuracy.
In some examples, the fourth rotating portion 1434 may be configured to be capable of driving the first rotating portion 1431, the second rotating portion 1432, and the third rotating portion 1433 to rotate about the axis of the base 141, and the fourth rotating portion 1434 may have a plurality of coarse adjustment screws 1404 for fixing the fourth rotating portion 1434 and the base 141. In this case, by loosening or tightening the plurality of coarse adjustment screws 1404 on the fourth rotation part 1434, the coarse adjustment state can be maintained by performing coarse adjustment of the rotation of the range finder 12 in the horizontal or second direction, and the accuracy of the range finding can be improved by performing fine adjustment by the second fine adjustment screw 1406 and the second return spring 1408.
In some examples, the fourth rotating portion 1434 may be integrally formed with the third rotating portion 1433.
In some examples, the rotation mechanism 143 and the base 141 are connected by a third bearing 1409. In this case, the rotation of the rotation mechanism 143 can be smoother.
