Description
Technical field
The present invention relates to the specific protein field of analytic instrument, relate in particular to a kind of high speed sample adding device.
Background technology
In full-automatic specific protein analyser, need a sample adding device to realize automatically adopting reagent, take a blood sample and adopting the functions such as damping fluid, with it, raise the efficiency.Existing sample adding device probably has following two kinds of implementations:
1, the gear train of gear and rack combination, this kind of mode be owing to being difficult to that tooth bar is carried out to accurate location, therefore whole gear train the motion process middle rack to rock degree of convergence larger, thereby shortened the serviceable life of whole mechanism.
2, adopt the combination of screw mandrel and line slideway, its manufacturing cost is higher, also higher to manufacturing accuracy and workman's device technical ability requirement, and whole device is comparatively huge.
Summary of the invention
The present invention is directed to a kind of high speed sample adding device that the sample adding device manufacturing cost of screw mandrel and line slideway combination in prior art is high and device is huge and propose, this high speed sample adding device is compared with the sample adding device of screw mandrel and linear guide rail type, not only cost-saving, and get a promotion at aspect of performance.
