3 synchronous rotary of component, so that two groups of lifting assemblies 3 simultaneously promote the blocking component 2 at same 1 both ends of testing tube, with
The control for realizing the soakage to sample to be tested sucking testing tube 1, improves the accuracy of erythrocyte sedimentation rate testing result.But this implementation
The specific structure of transmission component 53, which is not construed as limiting, in mode to be gear drive, V belt translation and/or chain conveyer, as long as energy
It is enough that the power of second driving mechanism 51 is passed into rotary shaft 54.
In order to obtain more accurate angle step pitch (rotational angle of valve opening arm 52), needed between driving wheel 531 and driven wheel 532
Suitable transmission ratio is set, it is preferable that the number of teeth of driven wheel 532 is the integral multiple of the number of teeth of driving wheel 531.
As shown in Figure 10, rotary components 5 further include positioning disk 55, and positioning disk 55 is fixed in rotary shaft 54, follow rotation
Axis 54 rotates together, and the velocity of rotation of positioning disk 55 is equal to the velocity of rotation of rotary shaft 54.The structure and valve disc 41 of positioning disk 55
Structure it is similar, also include multiple sectors, there are gaps between adjacent sector.Positioning disk 55 and 41 face of valve disc are arranged, when
When positioning disk 55 turns over the angle of a sector, positioning disk 55 can be with valve disc 41 again face.
Second detection device 56 and third detection device 57 are set on positioning disk 55, and second detection device 56 is fixed for detecting
Whether face is arranged for position disk 55 and valve disc 41, and third detection device 57 is used to detect the angle step pitch of positioning disk 55.Specifically, second
Detection device 56 is to reset optocoupler, and third detection device 57 is step pitch optocoupler.
The esr test device that present embodiment provides further includes conducting ring 7, and conducting ring 7 is set to valve opening arm 52 and rotation
The junction of axis 54.54 inner hollow of rotary shaft, control route are arranged in inside rotary shaft 54, guarantee that valve opening arm 52 can 360
Degree rotation, control route is neither exposed, and not will cause route kink.
In present embodiment, the quantity of conducting ring 7 is two, and two conducting rings 7 are set with two one-to-one correspondence of valve opening arm 52
It sets.
The course of work for the esr test device that present embodiment provides is as follows:
Step S1: lifting member 32 resets, so that eccentric end 321 is located at minimum point；
Step S2: positioning disk 55 resets, so that positioning disk 55 and 41 face of valve disc are arranged；
Step S3: starting rotary components 5, rotary shaft 54 drive two valve opening arms 52 to turn on specified sector 411, and
The eccentric end 321 of lifting member 32 is located in the age of a draught animal slot 421 of lift block 42；
Step S4: while starting two groups of lifting assemblies 3, under the action of two eccentric end 321, two equal edges of lift block 42
Vertical direction movement, but the direction of motion on the contrary, drive closure connector 21 vertically moving, tip 213 follows closure in turn
Connector 21 moves, and sealing element 24 is left at tip 213, and multiple side openings 212 are connected to second interface 222, so that test
Sample to be tested is sucked in pipe 1；
Step S5: when the soakage of testing tube 1 reaches default soakage, two the first driving mechanisms 31 are synchronized simultaneously to be turned
Dynamic, the eccentric end 321 of lifting member 32 no longer abuts the cell wall of the age of a draught animal slot 421 of lift block 42, in the elastic force and valve of elastic tube 23
Under the collective effect of the rigid restoring force of disk 41, the tip 213 of blocking component 2 and sealing element 24 are squeezed, and testing tube 1 is blocked
Firmly, the work of sampling terminates；
Step S6: testing tube 1 is vertically stood, and using the variation of liquid level in scanning means monitoring and test pipe 1, that is, is monitored red thin
The distance that born of the same parents sink within the unit time, and then obtain the measurement result of erythrocyte sedimentation rate.
Note that above are only better embodiment and institute's application technology principle of the invention.Those skilled in the art can manage
Solution, the present invention is not limited to particular implementations described here, are able to carry out for a person skilled in the art various apparent
Variation is readjusted and is substituted without departing from protection scope of the present invention.Therefore, although by embodiment of above to this hair
It is bright to be described in further detail, but the present invention is not limited only to embodiment of above, is not departing from present inventive concept
In the case of, it can also include other more equivalent implementations, and the scope of the invention is determined by the scope of the appended claims.
