Detailed Description
As shown in fig. 1-3, the present invention includes a driving motor 2 fixed on a mounting plate 1, a bracket 3 sleeved on an output shaft of the driving motor 2, a positioning shaft 4 fixed on the output shaft of the driving motor 2 and located above the bracket 3, and a reagent tray 5 disposed on the positioning shaft 4, wherein the reagent tray 5 is matched with the positioning shaft 4.
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.
In practical use, the present invention also needs a structure for preventing the reagent disk 5 from flying out from the positioning shaft 4, which is not a little reflected in the prior art, and the present invention can adopt the prior structures.
In order to realize automatic operation and realize the locking of the reagent disk and the positioning shaft under the condition of no need of manual operation, the invention discloses a locking mechanism.
As shown in fig. 1, 3, 4 and 5, the locking mechanism includes a clamping jaw 8 disposed on the bracket 3, an opening and closing device for opening and closing the clamping jaw 8, and a clamping strip 9 disposed at the lower end of the inner wall of the positioning hole of the reagent disk 5 for cooperating with the clamping jaw 8.
