Description

Combined floating board for learning swimming

Technical Field

The utility model relates to a combined floating plate for swimming learning, belonging to the technical field of swimming auxiliary equipment.

Background

Swimming is a survival skill, and has the functions of improving the functions of heart and lung, improving the sensitivity and coordination of the body, promoting appetite, accelerating digestion and absorption, improving the immunity of the organism, shaping the body shape of a body, improving the sleep quality and the like when participating in swimming exercise. Especially, since the swimming becomes the examination content of the middle school entrance sports, more and more parents hope that the children can master the swimming, and the swimming training in summer season of each year is abnormally exploded. Seventy-eight percent of the earth's surface is water, including the areas of oceans, rivers and lakes, and people are in the way of water at all times, so that many people are regrettable because a lifetime does not learn swimming.

Human beings are adapted to walk upright in the long-term evolution process, and the body is in a prone position when swimming. The change of body posture and the influence of buoyancy and pressure of water can make swimming learners fear water, so that the selection of a proper teaching auxiliary device in swimming teaching is very important. Swimming learning is a progressive process, and learners can better practice swimming technical actions by overcoming self gravity and buoyancy of water control as soon as possible in the learning process.

The teaching effect of combining the back float with the floating plate is better in swimming learning, but in practical teaching, the floating plate purchased in the market is not suitable for the swimming teaching of the infant due to the small body size and weight of the infant, so the back float is generally disassembled for the swimming teaching of the infant in the teaching, taking the breaststroke teaching as an example, when practicing breaststroke leg kicking, two hands simultaneously grasp the two folded disassembled back float plates; when practicing the hand leg cooperation, two hands take the kickboard that the back of the body floats and disassemble respectively, but along with proficiency's improvement, should reduce the quantity that the back of the body floats and the kickboard of hand gradually, traditional kickboard can't satisfy progressive process nevertheless, once only subtracts the kickboard in the learner hand, can make the learner not have the dependence, and then because fear the psychology leads to chocking water, arouse the teaching bottleneck and can't continue to give lessons.

SUMMERY OF THE UTILITY MODEL

The utility model provides a combined floating plate for swimming learning, which solves the problems that the existing floating plate can not meet the requirement of swimming learning step by step, the floating plate in the hands of a learner is omitted at one time, the learner can not depend on the floating plate, and further, the teaching bottleneck can not be continued due to water choking caused by fear psychology.

The utility model relates to a combined floating plate for learning swimming, which comprises a square first floating plate, wherein the first floating plate is divided into two second floating plates from the middle, one second floating plate is divided into two third floating plates, one third floating plate is divided into two fourth floating plates, connecting buckles are arranged between the adjacent floating plates, and each floating plate is provided with a through hole.

An elastic rubber sleeve is fixed on the side wall of the perforation. Preventing hand from being rubbed after the arm is inserted.

The perforated upper and lower end outside is equipped with annular brace table, and the both ends of elastic rubber cover be equipped with annular brace table complex turn-ups, all be equipped with the anticreep arch of dovetail type on the outer wall of turn-ups and elastic rubber cover, be equipped with on perforation inner wall and the annular brace table with the anticreep protruding complex dovetail type's anticreep recess. The adhesive strength of the elastic rubber sleeve can be increased, and the elastic rubber sleeve is prevented from falling off.

The connection eye-splice comprises a connection groove and a connection clamping block matched with the connection groove, a spring bolt is fixed on the inner side of the connection clamping block, a lock hook is arranged at the inner end of the spring bolt, a clamping groove matched with the lock hook is arranged at the inner end of the connection groove, and an opening is formed in the top of the clamping groove. The hand stretches into the opening, presses the latch hook top, can break away from the locking of latch hook, accomplishes the split, can carry out quick connection combination and split.

The connecting insert buckle comprises a connecting insert block and a connecting slot matched with the connecting insert block, and the connecting insert block is fixedly connected to each floating plate through a connecting bolt. The connection combination is more stable.

The utility model has the following beneficial effects:

when the combined floating plate is used for the cooperation exercise of hands and legs, the quantity and the size of the floating plate used by hands can be gradually reduced according to the degree mastered by an exerciser, so that a learner can gradually adapt to the reduction of the floating plate, and the combined floating plate is favorable for swimming learning.
