Abstract
The utility model relates to the field of instruments for surveying and mapping, in particular to the field of meridian instruments. In order to fulfill the aims, the following technical scheme is adopted: the device for finely adjusting a plumb line of a meridian instrument is characterized by comprising a bracket, wherein lug shafts are arranged on two sides of the bracket and are arranged in holes of a frame. The device has the advantage of being compact in structure, and compared with the original design, the appearance is slightly changed, the overall appearance is coordinate, and the device is easy and reliable to operate during debugging.
Description
Technical field
The utility model relates to the instrument of surveying and mapping field, is exactly meridian appearance field specifically.
Background technology
The meridian appearance is a kind of in the geodetic instrument.It both can do horizontal survey, also can carry out pedal line through the last turning down of instrument and measure.When just having begun the design operation, because the client is less demanding to the pedal line measuring accuracy, so structurally do not add micromatic setting.But along with the client improves the requirement of precision gradually, original structure has satisfied not requirement, just need on original structure, improve, and need simple possible, avoids profile and former profile that notable difference is arranged.The utility model is exactly in line with this principle, on original structure, has added the pedal line micromatic setting, makes accuracy of instrument reach client's accuracy requirement through debugging.
The utility model content
The purpose of the utility model is to overcome the deficiency of existing structure, and a kind of pedal line adjusting gear of new model is provided, and makes instrument telescope optic axis center when rotating around the axle center so just guarantee the precision that pedal line is measured perpendicular to the revolution axle center.
Meridian appearance pedal line micromatic setting is characterized in that: comprise carriage 6, there is gudgeon 7 the carriage both sides, and gudgeon is contained in the hole of frame 3.
During use, just can pipe lens barrel 1 be rotated within the specific limits when from frame, pushing control lever 2 aside, the telescope tube centre of gyration is exactly the gudgeon center.Respectively there is an adjustment screw 5 the carriage both sides, are used for adjusting the verticality of the telescope optic axis and the telescope tube centre of gyration.
The utility model has the advantages that: compact conformation, change not quite with former designed appearances, overall appearance is coordinated very much.Easy and simple to handle reliable during debugging.
Description of drawings
Fig. 1 is the utility model user mode synoptic diagram front view, wherein: 1, pipe lens barrel, 2, control lever, 3, frame, 4, attachment screw, 5, the adjustment screw, 6, carriage, 7, gudgeon, 8, eyepiece.
Fig. 2 is the utility model user mode synoptic diagram vertical view, wherein: 1, pipe lens barrel, 2, control lever, 3, frame, 5, the adjustment screw, 6, carriage, 7, gudgeon, 8, eyepiece.
Embodiment
Referring to Fig. 1, Fig. 2, meridian appearance pedal line micromatic setting is characterized in that: comprise carriage 6, there is gudgeon 7 the carriage both sides, and gudgeon is contained in the hole of frame 3.
Described carriage bottom is provided with four attachment screws 4.
Described carriage is provided with two adjustment screws 5.
During use, will manage lens barrel 1 and be fastened on the carriage 6 through attachment screw 4.When pushing control lever 2 aside, with hand swinging head lens barrel, the pipe lens barrel can be that the centre of gyration rotates by illustrated instrument gyratory directions within the specific limits with gudgeon 7 just.Predetermined distance hangs a pedal line in instrument the place ahead, when the pipe lens barrel rotates, from eyepiece 8, observes this pedal line, if the graduation groove in the instrument can not guarantee to overlap with this pedal line all the time, just need adjust with adjustment screw 5.
Concrete method of adjustment is: elder generation's observational error direction from eyepiece; Unclamp four attachment screws 4 (according to the screw position, decision screw tightness) of carriage 6 bottoms then, according to the direction of error that observes; With the tight the right on the adjustment screw 5 of both sides among Fig. 2 or the loose left side; Or the tight left side on pine the right, make the pipe lens barrel do micro-adjustment with respect to carriage 6, fastening again four attachment screws after adjustment finishes by illustrated adjustment direction.Finally should make the strictness of the telescope optic axis and the telescope centre of gyration become 90 °, the graduation groove overlaps with this pedal line all the time when also just having guaranteed the instrument revolution.
Claims (3)
1. meridian appearance pedal line micromatic setting, it is characterized in that: comprise carriage, there is gudgeon the carriage both sides, and gudgeon is contained in the hole of frame.
2. meridian appearance pedal line micromatic setting according to claim 1 is characterized in that: described carriage bottom is provided with four attachment screws.
3. meridian appearance pedal line micromatic setting according to claim 1 is characterized in that: described carriage is provided with two adjustment screws.
