Abstract

The invention provides a lead storage device for physical electrical experiments and a use method of the device. The device comprises a lead storage device body and a lead storage box; the lead storage device body comprises a lead casing, spools, a rotating electric connection structure, spool braking devices, a switch assembly, guide mechanisms and length measuring devices. The casing of a body of the lead storage box is foldable, a lead winds around the outer circular surface of a disc and is led out through guide rollers and a pair of pull rollers, the 180-degree leading-out position of the lead is adjustable through a semi-circular groove sliding rail, the switch assembly is further arranged on the lead storage box, the switch function of the lead storage box in a circuit is realized, finally, the folded lead storage box or the unfolded lead storage box can be placed in a lead storage case, and the lead storage box can be counted.

Description

technical field [0001] The invention belongs to the field of electricity, and in particular relates to a conducting wire storage device for physical and electrical experiments and a method for using the same. Background technique [0002] Physics is an experiment-based discipline, and many laws are introduced and verified through experiments. With the rapid development of society, science and technology are getting more and more advanced, and the experimental environment has also been greatly improved. During the experiment, the test wires are often very long, and students are troubled by connecting the circuit or smoothing the test wires after the experiment is completed. Wires that are too short cannot meet long-distance use, and wires that are too long bring great trouble to storage, and wires are often entangled with each other. In view of the above defects, it is necessary to design a retractable test lead storage device. Contents of the invention [0003] The purpo...
