Zusammenfassung: | The utility model relates to an auto-counting device for rope skipping which combines handles with a zero-resetting counter whose worm outer end is tightly fitted with joints of the skipping-ropes. The rotation of the ropes drives the joints of the skipping-ropes, thus drives the worm screw and makes the counting wheel do the corresponding rotation through worm wheels and change gears, and then skipping times are disassembled. The utility model has the advantages of simple structure, convenient operation, accurate and intuitive reading. The device can be widely used in rope skipping matches and qualification tests in primary and middle schools, and solves the present counting difficulties, such as the visual inspection and mouth-counting. |
