Abstract
The utility model relates to a chronometer, which chiefly comprises a telescope, a built-in scale, a reading mirror, a vertical shaft, and a laser centring device, wherein, the laser centring device is composed of a hollow bolt for fixing the chronometer and a laser transmitter in the hollow bolt. The beam center of the laser transmitter has the same shaft with the vertical shaft of the chronometer. The utility model can be formed by the modification of the existing optical chronometer to reduce eyepiece components of optical centering device of the original chronometer and the manufacture processing operation of the chronometer. The laser centring device in the chronometer has the advantages of simple structure, easy manufacture, and easy processing. The utility model has the advantages of easy centering, higher measurement precision, convenient use, less influence from adverse weather, and the convenient work of survey workers.
Description
Technical field
The utility model belongs to the surveying instrument field, particularly a kind of transit with laser alignment device.
Background technology
China measures the transit that uses in the operation now, generally comprises telescope, reading lens and built-in scale, vertical pivot and transit is fixed on hollow bolt on the tripod.Whether the centering website has two kinds of methods: the general measure precision is 6 " in the scope, is in measuring station dot center with plumb bob summit observation theodolite; Measuring accuracy requires " in the scope, whether to be in measuring station dot center with optical centering device eyepiece observation theodolite 2.Watch the method whether transit is in measuring station dot center for these two kinds, the road is also convenient when fine operation, but a chance cloudy day or a wind and rain sky, the user just is difficult to see clearly transit and whether is in measuring station dot center.Therefore, be difficult to guarantee the precision of measurement, the operation of also having to sometimes abandon measuring.
Summary of the invention
Problem to be solved in the utility model is: a kind of transit is provided, and this transit centering is easy, measuring accuracy is higher, easy to use and be not subjected to the influence of weather condition.
The technical scheme that the utility model provides is: a kind of transit, mainly comprise telescope, reading lens, built-in scale, vertical pivot and transit is fixed on hollow bolt on the tripod, vertical pivot has the laser alignment device, the laser alignment device is fixed in the hollow bolt body of transit, and be made of battery and generating laser, the beam center of generating laser is coaxial with the vertical pivot of transit.
The beam center of above-mentioned generating laser is coaxial with hollow bolt.
The utlity model has following advantage and good effect:
1. reduce the optical centering device eyepiece parts of former transit, reduced the production process of transit.
2. the laser alignment device in the transit is simple in structure, processing easily.
3. the utility model centering is easy, measuring accuracy is higher, easy to use and be not subjected to the influence of weather condition, be convenient for measuring personnel's operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of Laser bolt of the present utility model;
Fig. 3 is the electrical connection synoptic diagram of generating laser of the present utility model.
Embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises telescope 1, built-in scale and reading lens 2, vertical pivot 3 and transit is fixed on hollow bolt 8 on the supporting plate 5 of tripod, vertical pivot 3 has laser alignment device 7, laser alignment device 7 is fixed in hollow bolt 8 bodies of transit, and be made of battery 10 and generating laser 11, the beam center of generating laser 11 is coaxial with the vertical pivot of transit 3.
The utility model can adopt existing optical theodolite to convert: the former optical centering device eyepiece of transit parts save, and transit centering website parts are born by laser alignment device 7.When transit is installed, open the foot rest 6 of tripod, transit is placed on the supporting plate 5 of tripod, hollow bolt 8 passes the thread connection of supporting plate 5 with the base plate mesopore of tripod.The beam center of laser alignment device 7 is coaxial with the optics centering passage 4 of hollow bolt 8 and transit.Bolt 8 of the present utility model can be made as two parts up and down; Top 9 and bottom 12 are by being threaded: generating laser 11 is located at bolt bottom 12, can be by bolt bottom 12 loading and unloading batteries 10 of outwarding winding.When the utility model uses bolt 8 passed behind the tripod mesopore thread connection with base plate, open the switch 13 (referring to Fig. 2, Fig. 3) of laser alignment device 7, generating laser 11 penetrates a rectilinear light beam small red dot, and the user can conveniently see transit clearly and whether be in measuring station dot center.When light beam small red dot during, screw the hollow bolt 8 of transit over against the website center.
Claims (2)
1. transit, comprise telescope, built-in scale and reading lens, vertical pivot and transit is fixed on hollow bolt on the tripod, it is characterized in that: vertical pivot has the laser alignment device, the laser alignment device is fixed in the hollow bolt body of transit, and be made of battery and generating laser, the beam center of generating laser is coaxial with the vertical pivot of transit.
2. transit according to claim 1 is characterized in that: the beam center of above-mentioned generating laser is coaxial with hollow bolt.
