In analytical instrument; Generally also comprise constant temperature system or perhaps warmer, because temperature is very big to the reaction result influence during biochemical reaction, so the sensitivity of constant temperature system, accuracy directly influence measurement result; Present constant temperature system generally is sealed in the reflection dish in the big cavity; Heating arrangement heats airborne air, controls the temperature of reactant liquor through the temperature of control air, such mode heat transference efficiency is low, reactant liquor reach the thermally equilibrated time long, be prone to influenced by ambient temperature, temperature and float big; Influence the accuracy of measurement result easily, this just exists certain deficiency.
Summary of the invention
Technical matters to be solved by this invention is the deficiency that overcomes prior art, provide a kind of type of heating relatively directly, the heating-up time is faster and the constant temperature system of the Biochemical Analyzer of temperature precise control.
The technical scheme that the present invention adopted is: the present invention includes ringwise aluminium circle, oil pipe, loam cake; Said aluminium circle is equipped with several reaction cup locating slots; Be positioned at said several reaction cup locating slot inboards on the said aluminium circle and be provided with annular groove; Said oil pipe is around being arranged in the said annular groove, and said loam cake wraps the top of said aluminium circle, and the two ends of said oil pipe all pass said loam cake.
Said constant temperature system also comprises the dish that is rotationally connected, bearing seat, bearing, rotating shaft; The said periphery that is rotationally connected dish is connected with said loam cake; The position, intermediate portion is fixedly connected with said rotating shaft; Said rotating shaft, said bearing all are arranged in the said bearing seat, and said rotating shaft is rotatably assorted through bearing and said bearing seat, and the two ends of said oil pipe pass from its sidewall after all passing the top of said rotating shaft.
Said constant temperature system also comprises the oil seal seat between said bearing seat and said disk body; Said oil seal seat is enclosed within the said rotating shaft; Be provided with oil sealing, following oil sealing in the said oil seal seat; Saidly go up oil sealing, said oil sealing down all is enclosed within the said rotating shaft, and wraps said oil pipe in position that said rotating shaft passes.
Be provided with and be connected packing ring between said be rotationally connected dish and the said loam cake.
The top of said loam cake is provided with friction top, and said friction top is provided with the window corresponding with said several reaction cup locating slots and several signs corresponding with said window.
The invention has the beneficial effects as follows: owing to the present invention includes ringwise aluminium circle, oil pipe, loam cake, said aluminium circle is equipped with several reaction cup locating slots, is positioned at said several reaction cup locating slot inboards on the said aluminium circle and is provided with annular groove; Said oil pipe is around being arranged in the said annular groove, and said loam cake wraps the top of said aluminium circle, and the two ends of said oil pipe all pass said loam cake; Through such structure; Reach the fixedly totally-enclosed directly-heated of constant temperature, the heating-up time can be effective about three minutes with fast; The temperature control ratio is more accurate, so type of heating of the present invention is relatively more direct, the heating-up time is faster and the temperature precise control.
