Above-mentioned stroke learning-aid device, the connecting rod end is fixed with positioning cap.
Above-mentioned stroke learning-aid device, free leg inflatable packer are provided with buoyancy inflatable packer mouth.
Compared with prior art; Technique effect of the present invention is: the present invention can make the learner change reposefully and float on the surface; Know from experience decomposition, the complete interoperation in different each stage such as shank, arm part, breathing; Overcome the water funk feared state of mind, accomplish stroke action learnings such as breaststroke, backstroke, freestyle swimming freely; The present invention also can be used as the auxiliary trainer utilization of land; In teaching process, can more intuitively, also be convenient to teacher ' s guidance and error correction, help the beginner and grasp correct technical movements in the land, through education experiment; Can effectively improve teaching efficiency, the shortening course learning time reaches 37.65 ﹪.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 for the present invention along C among Fig. 1 to view.
The specific embodiment
Shown in Fig. 1, Fig. 2; A kind of stroke learning-aid device; Comprise belly air cushion 1, elastic cover 2, free leg inflatable packer 3, tranverse connecting rod active socket 4, positioning cap 6, tranverse connecting rod 7, connecting rod 8, sliding sleeve 9, fixedly jack box 10, ball bead type buckle connecting rod socket 11, arm pull peach shape road inner ring 12, outer ring, arm pull peach shape road 13 and U type limiting groove 14; Arm pull peach shape road inner ring 12 and outer ring, arm pull peach shape road 13 be not in same plane; Arm pull peach shape road inner ring 12 is connected with outer ring, arm pull peach shape road 13 through U type limiting groove 14, and being connected with ball bead type buckle connecting rod socket 11 of outer ring, arm pull peach shape road 13, ball bead type buckle connecting rod socket 11 passes through fixedly that jack box 10 is connected with connecting rod 8; Connecting rod 8 is provided with sliding sleeve 9, and connecting rod 8 ends are fixed with positioning cap 6; Belly air cushion 1 is connected with fixing jack box 10, and the tranverse connecting rod 7 that two ends are connected with free leg inflatable packer 3 is connected with connecting rod 8 through tranverse connecting rod active socket 4, and free leg inflatable packer 3 is provided with buoyancy inflatable packer mouth 5, and elastic cover 2 is connected with sliding sleeve 11.
During use, belly air cushion 1 is placed under the chest abdomen, two arms protract, and shank is placed on the connecting rod 8; Elastic cover 2 is enclosed within on two legs, and instep is pressed on the sliding sleeve 9, at this moment; Two connecting rods 8 are close to the outside of thigh, and air cushion floats on the surface body levels, prevent that shank from sinking.When two arms draw, grab water and following stroke, interior time receiving outside the inside and outside circle in arm pull peach shape road; Health is floated by air cushion; Can know from experience the branch water of arm; High elbow is embraced water, is received arm strokes such as elbow and receipts hand, can under the standard of the inside and outside circle in arm pull peach shape road, practise, and can prevent the downward Zha Shui of head, the flat generation of striking and can not lifting first-class phenomenon.Simultaneously; It is that the covering of the fan swing is done in the center of circle with ball bead type buckle connecting rod socket 11 that bipod drive sliding sleeve 9 is pushing away connecting rod 8, and bipod turns up, and makes shank and arch inboard aim at the kick direction backward; Because health receives the restriction of connecting rod 8, elastic cover 2; Can prevent to receive thigh, lift that stern is high excessively to be caused the wrong of kick direction or pedal the sky phenomenon, increase the kick area, improve the kick effect.
