AI Technical Summary
Technical Problem
In existing technologies, sample processing is cumbersome and inefficient, especially in experiments that do not require precise quantification. Manual measurement or weighing is complex and affects experimental efficiency.
Method used
Design a device based on the lever balance principle. The lever rotation drives the switch baffle to block the photoelectric coupling switch, so as to realize the rapid judgment of the sample weight. The mechanical displacement feedback is used to check whether the sample weight meets the standard.
Benefits of technology
It enables rapid determination of sample weight, reduces experimental errors, improves operational efficiency, and simplifies the sample placement process.

Abstract
The utility model discloses a device of judging sample weight in place relates to experimental instrument technical field, including mounting seat, mounting frame and stand, the mounting seat is installed with mounting frame, the mounting frame is installed with stand, the utility model is based on lever balance principle, realizes the quick judgment of sample weight in place through ingenious structure design, when sample is placed in the sample cup support of lever one end, weight drive lever rotates around pin shaft fulcrum, drives the switch baffle of other end synchronous displacement to the upper position, when sample weight reaches the purpose of experimental demand, the baffle moves to the inductive area of photoelectric coupling switch and is shielded and triggers switch power -off signal further, this design will weight parameter transform into the mechanical displacement of direct perception, whether the sample weight reaches the standard through the state change of photoelectric switch direct feedback, convenient for experimental personnel operation, has improved the efficiency of experiment, has reduced the experimental error that sample has not put or sample amount has not reached to cause.
