Technical Field

The invention relates to the technical field of training equipment, in particular to a device for practicing splits in sports dancing.

Background

In sports dance training, the split of two legs is an important training subject. In the existing two-leg split training, a trainer generally holds a support (such as a wall or other objects) by hands and then exercises slowly separating two legs (a skilled person can do exercise by directly separating two legs without holding the support).

In the prior art, no equipment for assisting a trainer to practice splitting exists, so that especially for beginners, due to the fact that the beginners need to hold a support by hands and then slowly diverge the legs, great inconvenience is brought to the trainees; in addition, in the manual exercise mode, the exerciser needs to pay large physical strength (large physical strength is needed when the two legs are gradually opened and closed), so that the exerciser often cannot achieve good training effect due to poor physical strength and short exercise time. Finally, the split movement is exercised manually, and when the learner has insufficient experience and excessive force for separating the two legs and excessive angle, the movement cannot be stopped in time, so that the probability of pulling the two legs of the practicer exists. In view of the above, it is desirable to provide a device that can assist a user in practicing splits and improve the exercise effect.

As shown in fig. 1 and 2, when the two legs of the exerciser are forked, the distance between the lower part of the two legs and the probe of the photoelectric switch is greater than a set value (for example, greater than 15 cm), the 3 feet of the photoelectric switch A8 do not output high level, the relay K4 keeps the power-off state, the input end of the control power supply and the normally closed contact end are closed, the first control circuit, the second control circuit, the two voltage regulators and the like are in the power-on working state, and the two legs of the exerciser can continuously descend. In practical situations, when the two legs of the trainee are forked at a certain angle and the distance between the lower part of the two legs and a detecting head of the photoelectric switch is smaller than a set value (for example, less than 15 cm, and the lower part between the two legs blocks an infrared beam emitted by the detecting head of the photoelectric switch), the 3 feet of the photoelectric switch can output high level, so that the relay K4 is powered on to attract the input end of the control power supply and the normally closed contact end to be open, the first control circuit, the second control circuit, the two voltage regulators and the like are all in a power-off non-working state, and the two legs of the trainee can not continue to descend to a proper height (at the moment, the trainee can withdraw the two feet from the two foot sleeves and readjust the detection height of the photoelectric switch A8 to a proper state); the probability of strain caused by overlarge legs of the practicer is prevented. In the invention, no matter the height of the two legs of a trainer descending or the height of the two legs rising feels any discomfort, the left hand can leave the button of the power switch S (the button type normally open contact power switch) immediately, so that the 1 st pin of the photoelectric switch A8 and the first and second control circuits are all powered off, the voltage regulator does not work any more, the two legs of the trainer do not move any more, and the function of an emergency switch is realized. In the circuit, the relays K, K1, K2, K3 and K4 are relays of model DC 24V.
