Detailed Description
As shown in the attached drawings 1-3, the utility model discloses a fix driving motor 2 on mounting panel 1, cover put at 2 output shafts of driving motor on bracket 3, fix on 2 output shafts of driving motor and be located the location axle 4 of bracket 3 top and set up the reagent dish 5 on location axle 4, reagent dish 5 and location axle 4 are mutually supported.
Evenly be provided with a plurality of lug 7 on the lateral wall of location axle 4, be used for between two adjacent lugs 7 with reagent dish 5 complex spread groove 15, be provided with the connecting block 6 that corresponds with spread groove 15 on the locating hole inside wall of reagent dish 5.
In order to facilitate the connection between the positioning hole on the reagent disk 5 and the positioning shaft 4, the outer side wall of the projection 7 is gradually inclined from bottom to top towards the direction close to the center of the positioning shaft 4.
Meanwhile, the bottom surface of the connecting block 6 is designed to be in an approximate V shape, and the left side wall and the right side wall of the lug 7 are gradually inclined towards the middle direction of the lug 7 from bottom to top, namely, the left side wall and the right side wall are also in an approximate inverted V shape.
When installing reagent dish 5 on location axle 4, need not consider the position relation of spread groove 15 and connecting block 6, only need with reagent dish 5 on the locating hole place location axle 4 can, rely on the gravity of reagent dish 5 self, combine the lateral wall of lug 7 slope, can realize the axle center of reagent dish 5 and the coincidence of the axle center of location axle 4, even a lot of misplaces when placing, also can realize automatic adjustment. And because the connecting block 6 has a structure form of a regular V shape or an inverted V shape on one surface or two surfaces matched with the convex block 7, even if the connecting block 6 is not opposite to the connecting groove 15 in the installation process, the automatic adjustment can be carried out through the inclined surface. The connection between the reagent disk 5 and the positioning shaft 4 is simpler and easier to operate.
The top surface of the tray 3 contacts the bottom surface of the projection 7 (i.e., the bottom surface of the coupling groove 15), and prevents the reagent disk 5 from falling off from below the positioning shaft 4.
The utility model discloses when the in-service use, still need a structure that prevents reagent dish 5 from 4 top flyouts in location axle, this kind of structure has the embodiment in prior art, the utility model discloses can adopt current these structures.
