Fine adjustment device of surveying instrument

Abstract

The invention discloses a fine adjustment device of a surveying instrument, which structurally comprises a fixing seat, an adjustment seat, an adjustment hand wheel, a height compensation knob, transverse pin shafts, a vertical pull rod, a pin shaft groove, a height compensation mechanism, wherein the adjustment hand wheel is perpendicularly connected with the middle of the right end surface of the adjustment seat and penetrates into the adjustment seat; the transverse pin shafts are movably embedded into the outer side surface of the pin shaft groove and extend to the right end of the pin shaft groove; the height compensation knob is perpendicularly connected with the middle of the front end surface of the fixing seat and penetrates into the fixing seat; the height compensation mechanismis movably connected with the left part of an internal cavity of the fixing seat and the adjustment seat; after fine adjustment each time, the fine change of the height of the adjustment seat of the device can be compensated timely; an error of the device in subsequent fine adjustment operation is avoided; the fine adjustment quality of the device and surveying precision of the surveying instrument are ensured; and the reliability of the device is effectively improved.

Description

technical field [0001] The invention relates to the technical field of fine-tuning devices, in particular to a fine-tuning device for surveying and mapping instruments. Background technique [0002] At present, there are many surveying and mapping instruments on the market. Although their specifications are not the same, especially their weights are even more different, the locking force required for clamping is also different. In addition to the differences in personal habits and strength, everyone will use surveying and mapping. The locking force of the instrument is also different, and some professional surveying and mapping personnel need to quickly replace different surveying and mapping instruments. The traditional fine-tuning device is difficult to operate by hand, and even requires special tools to operate, which is very difficult to operate. , Time-consuming and labor-intensive, obviously needs to be improved. [0003] However, in the prior art, in the operation pr...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a fine-tuning device for surveying and mapping instruments to solve the problem of fine-tuning the surveying and mapping instruments in the prior art. Afterwards, the height of the adjustment seat part of the equipment will change slightly, and the existing technology cannot perform a certain height compensation process for this error, which may cause errors in the subsequent fine-tuning work, affecting the fine-tuning quality of the equipment and the surveying and mapping of the surveying and mapping instrument Insufficient accuracy and reliability
