Current crashproof product probe Installation and adjustment mainly good installation personnel installation experience, find the road that straight as far as possible, then car is ajusted, and need personnel to hold test board test repeatedly in 100 meters of in automobile dead ahead, vehicle centerline could be found as much as possible, this mounting means is very high to the skill requirement of installation personnel, however, road can not be completely straight, and automobile also can not be ajusted completely, so this traditional mounting means, can not by probe dress just.Due to the characteristic of laser ranging, even if some error, also data can be measured, but the error range of data is very large, thus cause the precision of laser ranging greatly to reduce, how could be automobile probe location accurately fast, be the problem that those skilled in the art are concerned about.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of laser positioning bar, effectively can solve the quick pinpoint problem of automobile heat detecting head.
The technical scheme that the utility model solves is,
A kind of laser positioning bar, comprise base and be horizontally set on the laser guide pipe on base, laser guide pipe rear is provided with laser tube on base, the axis conllinear of the laser beam that laser tube emissions goes out and laser guide pipe; The side of described base is provided with the positioning magnetic steel be connected with car body.
The utility model novel structure is unique, advantages of simple, and easy to operate, cost is low, can positioning car center accurately, substantially increases the installation and adjustment efficiency of probe, easy to use, effective, has good Social and economic benef@.
