Description

Windage formula suspention swimming land special ability training aids

Technical field: the utility model relates to the swimming exercise training aids, particularly a kind of land special ability exercising device.

Technical background: swimming is one of sports item; The competitive swimming sportsman needs very strong special ability like, stamina of speed and strength endurance; And that the swimmer moves about in water is fast; Need advance at the resistance that rational technical movements lean on floating power that both arms and both legs paddling are pedaled the movable property life to overcome water down, want to create better achievement, only bad in the stamina of speed and the strength endurance effect of working in water both arms and both legs; Be that the resistance antagonism that training process produces is very limited because the liquid property sportsman of water does not fixedly have fulcrum.General motion person need use the specialized training equipment training to improve this ability on land.The exercising device of swimmer's use at present has rubber bar training aids and the dynamo-electric training aids of magnetic; The sources of resistance that these two kinds of exercising devices produce is the elasticity of rubber bar and the magnetic field electromagnetic quantities that magnetic electromechanics produces at electric current; The former increases resistance by the quantity that increases the rubber bar, and the latter increases resistance through strengthening electric current, and person's shortcoming is after to be resistance increase; Athletic speed of actions slows down; Thereby influence the raising of stamina of speed, and both only can do the training of both arms, and the training of both legs need lean on other exercising device to accomplish.

Summary of the invention: overcome the deficiency of prior art, design a kind of windage formula swimming exercise land special ability training aids of pedaling the resistance that drives air blade rotation generation with sportsman's both arms and both legs paddling.Windage formula suspention swimming exercise land special ability training aids has a steel body framework, and a root inclined-plane slide rail is arranged at top, and two sliding sleeves are arranged above; Hang with horizontal pulley below the sliding sleeve, horizontal two pulleys are installed with suspender belt, and the suspender belt bottom connects hangs pocket; The athletic chest belly of slinging makes the sportsman unsettled, and athletic upper body, arm and shank are unsettled in the front and back of hanging pocket; There is the air blade support steel body framework front, and air blade central shaft outer end is fixed with a small flywheel gear wheel, the flywheel gear wheel have chain and back level driven big flywheel around; Flywheel is fixed with little gear wheel around the outer end, have the initiatively big flywheel of chain and vertical upper around, initiatively big flywheel has 4 small flywheel gear wheels around inner circumferential; Have chain to hold above respectively, two ends is open, wherein; Open link end down and return around directive wheel on the horizontal back-moving spring that is connected the air blade frame bottom, upward open chain connects driving wire rope, and wherein 1 and 4 upwards through the directive wheel of kicking one's legs after front jockey wheel above the steel body framework is again above the process steel body framework; Connect footmuff respectively, 2 of upward open chain stretches out from guard shield through the arm pull directive wheel and connects gloves respectively with 3 the driving wire rope horizontal-extending that is connected, and fixes one on the air blade tilted supporter and catches up with magnetic inductor; The air blade identical bits is fixed a magnetic patch; Initiatively big flywheel ring is fixing photoelectricity fluted disc outward, and there is fixing photoelectric sensor in the outside, and there are a shell fragment machine and display in the outer top of backplate.The utility model operation principle: athletic chest belly is lain prone and is being hung on the pocket; Arm and shank are unsettled in the front and back of hanging pocket; Gloves, footmuff are enclosed within on both hands and the both feet, and both hands are done the water skiing action of breaststroke or swimming, butterfly stroke certainly, and both feet are kicked one's legs or footwork; Be connected driving wire rope and produce displacement backward when arm pull makes when kicking one's legs; Drive 4 small flywheel gear wheels and rotate and drive initiatively flywheel rotation greatly, the big flywheel of transmission is fixed with little gear wheel around the outer end and rotates with 1: 3 speed, and the big flywheel of transmission drives driven big flywheel rotation around outer end denticle wheel; Driven big flywheel drives the outer small flywheel gear wheel of air blade and rotates generation wind-force at a high speed and driving wire rope is produced same resistance with 1: 3 drive air blade; The resistance that is wind equals player motion speed, and speed of actions is from athletic strength, and the product of speed of actions and strength and time is the total amount of motion.After action was backward accomplished, back-moving spring retracted original position with driving wire rope, drive initiatively small flywheel gear wheel idle running, and this moment, air blade utilized rotatory inertia to continue rotation.In training process, the big I of speed of actions, wind-force resistance convert numeral or curve to through photoelectric sensing number of times signal and the magnetic field impulse number of times signal A/D through single-chip microcomputer and on showing, show or be docked with printout on the printer.

The utility model sportsman can train with the action of its breaststroke in swimming pool is simulated in the land, freestyle swimming, butterfly stroke; Overcome same resistance with speed of actions; Can effectively improve stamina of speed, strength endurance ability, improve the swimming exercise achievement fast.The data of its speed of actions, work done resistance and training burden can be used as the foundation of sentific training.Apparatus structure is simple, and usage space is little, the convenient use.
