A running lap counting device for track and field sports

Abstract

The invention relates to the technical field of lap counting equipment, and discloses a running lap counting device for track and field sports, which includes a frame, a lap counting device is fixedly installed inside the frame, and both left and right ends of the lap counting device are fixedly mounted with The fixed plate is fixedly equipped with an electromagnetic ring inside, the inside of the electromagnetic ring is rotatably connected with a conductive rod, and a coil spring is fixedly installed inside the conductive rod. The running circle counting device for track and field sports, by fixing and wearing the device on the athlete, during the athlete's exercise, the conductive rod rotates inside the electromagnetic ring, and the energized wire on the conductive rod cuts the magnetic induction line inside the electromagnetic ring Movement generates an induced current. As the movement becomes more intense, the faster the conductive rod cuts the magnetic induction line, the greater the induced current is generated, so that the induced current can be stored in the power supply device to provide Stabilize electricity.

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...
