Description
Technical field
The utility model relates to a kind of sports apparatus, especially a kind of breaststroke stroke study stop.
Background technology
Swimming exercise is liked by numerous people deeply, has abundant mass foundation, and especially breaststroke is the most laborsaving (requiring minimum to swimmer's physical efficiency), most popular stroke, is also the stroke of beginner's first GPRS.But, from sport technique segment: four kinds of strokes (breaststroke, freestyle swimming, backstroke, butterfly stroke), require that link is maximum with the stroking technique of breaststroke, such as: at the end of (1) breaststroke arm is struck, require that large arm becomes 80 degree of angles with trunk; (2) breaststroke leg action, at the end of receiving leg, require that the angle that leg and trunk are formed is spent 120-140, and two knee inboard knee width and practitioner's shoulder is with wide; (3) breaststroke leg action is received in leg action, at the end of receiving leg, requires that practitioner's heel will receive the position near buttocks.The code requirement of these actions, brings a lot of obstacle and fascination to the study of the stroke of beginner, only learns by oneself being difficult to grasp completely with fan, the nonstandard phenomenon ubiquity of breaststroke stroke.
At present, beginner wants the specification stroke grasping breaststroke, method participates in swimming training class more easily, under specialized coaches instructs, usually need to explain through: breaststroke leg action technology, breaststroke leg action land drill, the leg action of breaststroke leg is practised under water, breaststroke hand motion is explained, breaststroke arm part action land drill, these links are practised in the action of breaststroke arm part under water, also will under the supervision at any time of swimming instructor, carry out repeating the dynamic stereotype that (usual land drill with practise needing doing several thousand times under water even up to ten thousand secondary) could form specification, be waste time and energy.
In view of this, breaststroke stroke difficulty of learning degree how is reduced and the action of specification breaststroke stroke becomes the problem that those skilled in the art need solution badly.
Chinese patent CN 203507464 U discloses a kind of breaststroke beginner leg auxiliary apparatus, its abdominal fixing strap is fixed on two relative sides of belly fixed head, two leg baffle plates are fixed on two drift angle places of belly fixed head broad side surface respectively in splayed, each leg baffle plate medial surface is fixed with a thigh support board, and the angle between each leg baffle plate bottom surface and the bottom surface of belly fixed head is
for 120-140 °.But, this patent is only provided with leg baffle plate and carries out spacing to leg, can not carry out spacing to arm and heel, utilize this learning device can not meet the technical requirement of large arm and the angle of trunk, the position of heel etc. at the end of breaststroke is struck, this patent does not have flotation gear yet, can not ensure the safety of swimmer.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of breaststroke stroke to learn stop, as teaching tool, improve traditional teaching method, reduce the working strength of coach greatly, simultaneously, the thought of thorough eliminating learner is worried, thus improves efficiency of teaching.
For achieving the above object, the utility model adopts following technical proposals:
A kind of breaststroke stroke study stop, comprise upper limbs limiting plate, lower limb limiting plate and back floating plate, described upper limbs limiting plate and lower limb limiting plate are fixed by trip bolt or Tenon, and described back floating plate is connected on lower limb limiting plate by bondage silk ribbon, described upper limbs limiting plate is in " Y " type, described upper limbs limiting plate comprises gripper shoe I, described gripper shoe I top is circular arc, laminating human body neck place, avoid when utilizing the utility model to practise, causing neck place uncomfortable, described gripper shoe I has outward extending two the arm limiting plates corresponding with human upper limb (" Y " type both wings), described gripper shoe I and two arm limiting plates are in two Different Plane, the angle of described two arm limiting plates is 160 degree, play the restriction to arm, meet breaststroke " at the end of arm strikes, require large arm become 80 degree of angles with trunk " technical requirement, the cross section of described arm limiting plate is circular arc, better laminating human arm, play better position-limiting action, described lower limb limiting plate is in " Y " type of falling, described lower limb limiting plate comprises gripper shoe II, described gripper shoe II has outward extending two the leg limiting plates corresponding with human body lower limbs (" Y " type both wings), described gripper shoe II and two leg limiting plates are in two Different Plane, the angle of described two leg limiting plates is 80 degree, described leg limiting plate (fall " Y " type both wings) and the angle of gripper shoe II bottom surface are 120-140 to spend, the junction of described leg limiting plate and gripper shoe II is circular arc, better laminating human body lower limbs, meet ergonomics, muscle when swimming with human body, the motion state of bone matches, when preventing from receiving leg release, leg comes to harm.
Described upper limbs limiting plate and lower limb limiting plate are integral structure.
Described gripper shoe I is evenly equipped with many row length-adjustment holes holes, described gripper shoe II is provided with the length adjustment hole corresponding with length adjustment hole in gripper shoe I, described gripper shoe I and gripper shoe II are fixed by multiple trip bolt, regulate the correspondence of hole fastening by different length between gripper shoe I and gripper shoe II, equitant length between upper limbs limiting plate and lower limb limiting plate can be regulated, the long people of different height body can be catered to and use.
Described lower limb limiting plate is also provided with heel limiting plate, described heel limiting plate is connected on lower limb limiting plate by heel limiting plate connecting rod, described heel limiting plate connecting rod and gripper shoe II, leg limiting plate be not all in same plane, the angle of described heel limiting plate connecting rod and gripper shoe II is 135 degree, can limit the position of heel during receipts leg release, heel is extended near buttocks rear 10 centimeters of practitioner.
Described leg limiting plate is provided with chute and knee limiting plate, on described knee limiting plate, side is provided with U-shaped groove, described knee limiting plate opposite side is provided with screw, the screw of knee limiting plate is connected with clamp nut through chute, by knee limiting plate and leg limiting plate fastening, ensure in breaststroke stroke learning process, the U-shaped groove of knee limiting plate and practitioner receive the thigh after leg, fit in knee position, and two inside the knee spacing and practitioner's shoulder with wide.By knee limiting plate being fastened on the diverse location of chute, when the people that can meet different shoulder breadth learns breaststroke two inside the knee spacing and shoulder with wide.Chute on leg limiting plate is hollow structure, and when can reduce swimming, water is to the resistance of limiting plate, simultaneously also can reduce the buoyancy of water to limiting plate, reduce to swim into time the limiting plate lift upwards that produces, make swimmer experience the state of breaststroke more really.
