Description
Technical field
The utility model relates to surveying and locating device, is specifically related to a kind of three dimensional coordinate measuring prism bar.
Background technology
Three-dimensional coordinate measurement is applied very extensive in municipal works.Compared with solving position coordinate problem with the method that conventional plane bidimensional adds elevation one dimension, three-dimensional coordinate measurement, while raising measuring accuracy, greatly reduces the labour intensity of survey crew.Prism bar is requisite equipment in three-dimensional coordinate measurement, and its principle of work is: the signal sent from total powerstation by prismatic reflection, the distance between surveying instrument to prism, thus the three-dimensional coordinate calculating unknown point.
In measuring process, the positioning precision of prism bar determines the co-ordinate measurement accuracy of unknown point.The prism bar sold in the market and prism junction are toroidal notch, are easy to chute and rotation in use.The prism body of rod is when fixing scale, and the friction force only by screw and rubber and alloy material fixes, and in three-dimensional coordinate measurement, because friction force is too little, scale easily slides, and affects measuring accuracy.Therefore it is very important for carrying out improvement to existing prism bar.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of three-dimensional coordinate is provided to measure prism bar, this prism bar connects prism by arranging switching device on body of rod top, and by screw lock fixed transfer device, makes prism in operation can not chute and rotation.
The utility model object realizes being completed by following technical scheme:
A kind of three dimensional coordinate measuring prism bar, comprise the body of rod and prism, it is characterized in that described body of rod top is provided with the switching device connecting described prism, described switching device comprises reducing sleeve and adapter, and described reducing sleeve has a groove, and described adapter is plugged in described groove, therebetween nested relationship is formed, fixed by screw lock between described adapter and described reducing sleeve, wherein said adapter is fixedly connected with described prism, and described reducing sleeve is fixedly connected with the described body of rod.
Described adapter outer wall is provided with a ring groove, described screw head runs through described reducing sleeve and peaks on described annular groove to complete described being locked.
Described adapter top has the threaded hole connecting described prism, and being fixedly connected as therebetween is threaded.
Have the threaded hole connecting the described body of rod bottom described reducing sleeve, being fixedly connected as therebetween is threaded.
The described body of rod is made up of upper hollow stem and lower hollow stem, and described upper hollow stem is inserted in described lower hollow stem, and on described upper hollow stem, uniform intervals is provided with jack, and both are spacing fixing by pin rod.
Describedly spacingly fixedly to refer to: be held on described lower hollow stem in upper hollow stem described in the injection of described pin rod.
The utility model has the advantages that, be connected reliable between prism with the body of rod, error during measurement can be reduced, ensure that data precision, improve measurement operating efficiency.
