Abstract
The utility model provides a laser automatic leveling instrument, comprising a main body, a telescope objective, a telescopic ocular and the like, wherein the telescope objective is arranged at the front part of the main body; a laser transmitter, an image transmission objective, a beam splitter prism and a dividing board are located inside the main body; and the beam splitter prism is located between the image transmission objective and the dividing board. The laser automatic leveling instrument is characterized by comprising a handle, a laser device cover and a laser correction screw; the laser transmitter is located above the beam splitter prism; a laser correction screw is arranged on the laser transmitter; the laser device cover is arranged on the laser correction screw; the laser device cover is connected with the main body; and the handle is arranged on the main body. The laser automatic leveling instrument provided by the utility model has the beneficial effects that the laser correction screw is mounted on a laser device; a laser beam emitted by the laser device and a collimation line of a telescope of the leveling instrument keep coaxial and con-focal by adjusting the laser correction screw; the service life of the instrument can be prolonged; and the laser automatic leveling instrument is simple to adjust.
Description
Technical field
The utility model relates to the instrument of surveying and mapping field, relates in particular to a kind of automatic compensated level.
Background technology
At present, the automatic compensated level technology is ripe both at home and abroad, and has formed large-scale production.Laser automatic level is a kind of novel spirit-leveling instrument that occurs recently, it is at common automatic compensated level laser instrument to be installed, that the laser beam that laser instrument sends and spirit-leveling instrument telescope collimation line keep is coaxial, with burnt, solved automatic compensated level and be not easy for problem than details in a play not acted out on stage, but told through dialogues ground.Announced a kind of laser automatic level such as Chinese patent 200820141979.4, comprise the spirit-leveling instrument light path that is consisted of by front group of object lens, focusing lens group, image rotation prism group, graticule group, eyepiece group, it is characterized in that: described spirit-leveling instrument light path also comprises block prism and laser instrument, block prism is arranged between described image rotation prism group and the graticule group, laser instrument is arranged on the below of block prism, and the cross curve center of the light source of laser instrument and differentiation plate group is symmetrical in respectively 45 ° of reflectings surface of block prism.Although this patent has solved automatic compensated level and has not been easy for problem than details in a play not acted out on stage, but told through dialogues ground, but service time one is long, displacement appears in laser instrument easily, causes its laser beam of sending not keep coaxial, burnt together with spirit-leveling instrument telescope collimation line, has affected the normal use of instrument.When adjusting laser positions, need laser automatic level to be taken apart troublesome poeration.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of laser automatic level, comprise main body, telephotolens, telescopic ocular, the laser instrument switch, generating laser, biography is as object lens, Amici prism, graticule, body front part is provided with telephotolens, the rear portion is provided with telescopic ocular, sidepiece is provided with the laser instrument switch, the laser instrument switch is connected with generating laser, generating laser, biography is as object lens, Amici prism and graticule are positioned at main body, Amici prism is between passing as object lens and graticule, characterized by further comprising handle, laser instrument lid and laser-adjusting screw, described generating laser be positioned at Amici prism directly over, which is provided with the laser-adjusting screw, the laser-adjusting screw is provided with laser instrument lid, the laser instrument lid is connected with described main body, and described main body is provided with handle.
Described generating laser is semiconductor laser transmitter.
Described laser instrument lid is connected with described main body screw.
The beneficial effects of the utility model are: at laser instrument the laser-adjusting screw has been installed, can guarantee that by adjusting laser-adjusting screw the laser beam that laser instrument sends keeps coaxial, burnt together with spirit-leveling instrument telescope collimation line, prolonged the serviceable life of instrument, and regulated simple.Outside the laser-adjusting screw, use laser instrument lid, can prevent that dust etc. from exerting an influence to the laser-adjusting screw; Add handle, make things convenient for the carrying of this spirit-leveling instrument.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Among the figure, 1, main body; 2, telephotolens; 3, telescopic ocular; 4, laser instrument switch; 5, generating laser; 6, pass as object lens; 7, Amici prism; 8, graticule; 9, handle; 10, laser instrument lid; 11, laser-adjusting screw.
