Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-3, a sample feeding tray for a flow cytometer includes a bin body 1, and it should be noted that the flow cytometer may be installed in the bin body 1, so that when a culture dish or a sample bottle is moved into the bin body 1, the flow cytometer in the bin body 1 may analyze and detect a cell sample in the culture dish or the sample bottle.

The inner wall of the bin body 1 is rotationally connected with a transverse moving threaded rod 2, the transverse moving threaded rod 2 is connected with a support 4 in a threaded manner, the upper end of the support 4 is fixedly connected with a sample tray 6, two sliding grooves 8 are formed in the upper end of the sample tray 6, a bracket plate 9 is slidably connected in each sliding groove 8, a sucker 10 is fixedly arranged at the upper end of the bracket plate 9, a double-end threaded rod 7 is rotationally arranged on the sample tray 6, the double-end threaded rod 7 extends into the two sliding grooves 8, and the two bracket plates 9 are respectively connected with thread segments of the double-end threaded rod 7 in a threaded manner. The sucker 10 is made of soft rubber materials, and the two sliding grooves 8 are symmetrically arranged along the axis of the sample tray 6.

The lower extreme rotation of support 4 is connected with a plurality of gyro wheels 5, and rolling groove 3 has been seted up to the interior bottom of storehouse body 1, and gyro wheel 5 roll setting is in rolling groove 3. It should be noted that, through setting up rolling groove 3 and gyro wheel 5, not only can make things convenient for support 4 to follow rolling groove 3 lateral shifting, rolling groove 3 only slightly is wider than gyro wheel 5 simultaneously, so can carry out spacing to support 4, makes it can not rotate, so when sideslip threaded rod 2 rotates, the removal of horizontal direction only can take place for support 4.

The lower end of the lifting screw 11 is fixedly connected with a rotating plate 12, and the rotating plate 12 is positioned below the bracket 4.

The side wall of the bin body 1 is rotationally connected with an adjusting wheel 14, and the transverse moving threaded rod 2 penetrates through the side wall of the bin body 1 and is fixedly connected with the adjusting wheel 14.

According to the utility model, the double-end threaded rod 7 can be rotated according to the specification of the culture dish or the sample bottle, and the interval distance between the bracket plate 9 and the sucker 10 is adjusted, so that the sucker 10 can be matched with culture dishes or sample bottles with different sizes, and then the bottom of the culture dish or the sample bottle is adsorbed by the sucker 10 by pressing the culture dish or the sample bottle, so that the fixation of the culture dish or the sample bottle is completed.

Then the adjusting wheel 14 is rotated to enable the transverse moving threaded rod 2 to rotate, so that the support 4 and the sample tray 6 can move towards the inside of the bin body 1, and the cell loss instrument conveniently installed in the bin body 1 can analyze and detect the culture dish or the sample bottle fixed in the sample tray 6. After the detection is finished, the adjusting wheel 14 can be reversely rotated, so that the sample tray 6 is moved out of the bin body 1, at the moment, the culture dish or the sample bottle is grasped by one hand, the rotating plate 12 is rotated by the other hand, the lifting screw 11 is driven to rotate and move upwards, the top plate 13 can be pushed to move upwards, and the culture dish or the sample bottle can be driven to be separated from the suction cup 10.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
