The utility model relates to the technical field of
medical equipment, in particular to a portable tray for medical examination, an anti-toppling mechanism comprises a mounting rack, the mounting rack is fixedly connected into a tray body, the upper end of the mounting rack is connected with a plurality of placing grooves at equal intervals in the length direction, grooves are formed in the two sides of the interior of each placing groove, and an anti-toppling mechanism is arranged in each placing groove. The upper end of the interior of each groove is rotationally connected with an
extrusion plate, the bottom end of each
extrusion plate is located outside the corresponding groove, each
extrusion plate is fixedly connected with a spring, and one end of each spring is fixedly connected to the corresponding groove. A small
bottle of
reagent is inserted into the placement groove, the small
bottle of
reagent moves downwards to push and press the extrusion plate, the extrusion plate rotates towards the groove, the extrusion plate extrudes the spring in the rotating process, the spring generates elastic force after being pressed, and the elastic force generated by the spring pushes the extrusion plate, so that the extrusion plate is in extrusion contact with the small
bottle of
reagent; and the small-bottle reagent cannot topple over in the transferring process, and cannot collide with the tray body.
