Abstract

The utility model relates to an aiming device for arranging instruments. The utility model comprises a lens barrel < 3 >, a reflecting mirror seat < 21 > which is arranged at one end of the lens barrel < 3 > and is provided with a corner cube mirror < 1 >, a hollow objective lens seat < 20 > which is arranged in a sliding mode in the lens barrel < 3 >, an objective lens < 4 > which is arranged at the front end of an axial inner hole < 24 > of the objective lens seat < 20 >, and a focusing hand wheel < 11 > which is sheathed on the lens barrel < 3 > and is rotatablely connected with the lens barrel < 3 >, wherein, a laser pipe < 17 > is arranged on the outer side of the back end of the axial inner hole < 24 >. A laser beam can be focused for imaging and a laser is focused by the objective lens after passing through the axial inner hole of the objective lens seat. Then, the laser is reflected to the ground by the corner cube mirror. The utility model has no requirement of collimation by eyes and convenient operation and can be regarded as the aiming device for instruments, such as a theodolite, etc.

Description

Settle instrument to point apparatus

Technical field

The utility model relate to a kind of transit instruments such as (total powerstations) to point apparatus.

Background technology

When using transit (total powerstation) to measure, at first on tripod, allocate instrument, make instrument vertical pivot centrally aligned ground survey coordinate points, the counter point device device that is absolutely necessary wherein, the optical plummet of Shi Yonging traditionally, comprise a lens barrel, be arranged at the mirror unit that corner cube mirror is housed of an end of lens barrel, be arranged at the objective holder of the hollow in the lens barrel slidably, be arranged at the object lens of leading section of the axial bore of described objective holder, a focusing handwheel that is enclosed within on the lens barrel and is rotatably connected with lens barrel, the sidewall of described focusing handwheel has helicla flute, have the gathering sill that penetrates on the described lens barrel vertically, be inserted in the helicla flute after a guiding projection that is fixed on the objective holder passes gathering sill; The back outside at objective holder is provided with graticule, and the back survey of graticule is provided with eyepiece.This counter point device in use, gauger's eyes need move around, and observe simultaneously in the counter point device visual field whether a graticule center to be aimed at the ground survey point, so user's operation trouble.

Summary of the invention

The purpose of this utility model is to provide a kind of and replaces the optics graticule with light-emitting device, makes and can launch a branch of light beam coaxial with the instrument vertical pivot to point apparatus, is implemented in the measurement Anping instrument more quickly.

The technical solution of the utility model is: a kind of settle instrument to point apparatus, comprise a lens barrel, be arranged at the mirror unit that corner cube mirror is housed of an end of lens barrel, be arranged at the objective holder of the hollow in the lens barrel slidably, be arranged at the object lens of leading section of the axial bore of described objective holder, a focusing handwheel that is enclosed within on the lens barrel and is rotatably connected with lens barrel, the sidewall of described focusing handwheel has helicla flute, have the gathering sill that penetrates on the described lens barrel vertically, be inserted in the helicla flute after a guiding projection that is fixed on the objective holder passes gathering sill; The outside, rear end of described axial bore is provided with laser tube.

The utility model compared with prior art has following advantage:

But the laser beam focal imaging, make laser through after the axial bore of objective holder again by object lens focusing, reflex on the ground by corner cube mirror, do not need with the eyes aiming, easy to operate.
