Description

A kind of light projecting calibrating apparatus

The utility model relates to the surveying instrument class, relates to a kind of building operation especially, the light projecting calibrating apparatus of usefulness is installed.

The method of demarcation perpendicular line commonly used is many to lie in line with weight, and utilize gravity and form perpendicular line vertically downward, yet, the weight counterweight is taken with inconvenience, is subjected to external force to shake heavy curtain easily and produces moving partially, could revise the side-play amount of fulcrum after the time-consuming wait swing of palpus is stablized in the operating process, very inconvenient in the operation, horizontal demarcation is then poured water with water pipe, with the horizontal light microscopic at observation two ends, must two people operate, and water pipe is poured water, the wet inconvenience of filtering, pipeline is intertwinded, and gets in the way, and is very inconvenient.

For these reasons, industry designs a kind of stereoprojection and demarcates light projector, its application number in Taiwan is: 80107192, its notification number is: 174044, its primary structure is that mode of laser is mounted on a body interior, body interior is provided with catoptron and mounting for grating in addition, this body is that the universal joint with sphere freely is suspended on the frame, utilize laser projections in catoptron and mounting for grating, the directional light cylinder that penetrates in vertical direction or the projection of horizontal direction static fixing on sensitive surface, simultaneously can produce the scanning projection mode by the catoptron rotation, making the light cylinder that reflects rotate light projector continuously is that the continuous straight line shadow of vision or draw straight line shadow or the ring of light that draws are thought stereoprojection, light projector or fixed point are demarcated.

Improved the shortcoming of traditional demarcation mode though light projector is demarcated in this stereoprojection, yet, still had and do not improve part and following shortcoming to the greatest extent in its structural defective:
