Running circle counting device for track and field sports

Abstract

The invention relates to the technical field of circle counting equipment, and discloses a running circle counting device for track and field sports, the device comprises a frame, a circle counting apparatus is fixedly mounted in the frame, fixing plates are fixedly mounted at the left end and the right end of the circle counting apparatus, and electromagnetic rings are fixedly mounted in the fixing plates, the interiors of the electrmoagnetic rings are rotationally connected with conductive rods, and coil springs are fixedly installed in the conductive rods. According to the running circle counting device for track and field sports, the device is fixedly worn on the body of an athlete, in the sports process of the athlete, the conductive rods rotate in the electromagnetic rings, an electrified wire on the conductive rods performs magnetic induction line cutting movement in the electromagnetic rings, induced current is generated, and the more violent the sports is, the faster the magnetic induction line cutting speed of the conductive rods is, the larger the generated induction current is, so that the induction current can be stored in a power supply device, and stable electric power is provided for the operation of the circle counting apparatus.

Description

technical field [0001] The invention relates to the technical field of lap counting equipment, in particular to a running lap counting device for track and field sports. Background technique [0002] Long-distance running is a very popular fitness sport. The test of long-distance running sports performance is usually done manually, that is, corresponding to each sport, a special tester and testing equipment need to be configured, so that the athletes can be accurately measured. Laps in practice, whether in a race or in practice, need to be counted and timed exactly this way. [0003] However, if this method is used in the daily training of athletes, it will cause a waste of manpower, and it is also very unfriendly to the individual training of athletes. It is very inconvenient to need the company of the tester for each training. Therefore, now There is an urgent need for a wristband that can be used by athletes to train individually. During use, the number of running circle...
