Description
Technical field
The utility model relates to a kind of swimming equipment, specifically refers to load adjustable swimming servicing unit.
Background technology
Swimming is one of generally acknowledged best body building, has good train on to the cardiopulmonary of human body and the circulatory system.Swimming both can be carried out also can carrying out out of doors at swimming pool; swimming fan often can be subject to the puzzlement of the problems such as safe swimming, interest and the bad adjustment of exercise intensity when carrying out swimming instruction; people wish that the security that a kind of swimming aid material can strengthen swimming exercise has interest simultaneously; and be convenient to adjustment movement intensity, can as the effective auxiliary appliance strengthening swimming physical training.
At present, kind is more for the buoyant apparatus of swimming and study equipment, as " copycat ", " swimming is happy precious ", " lifebuoy " and " life vest " etc., but the function of these swimming equipments is often comparatively single, there is such or such defect, if " lifebuoy " and " life vest " is mainly as the security strengthening swimming, is not easy to study and uses, more can not regulate the training strength of swimming; " swimming is happy precious " learns to use mainly as beginner; " copycat " can be used as a kind of safe swimming equipment that adult uses, but can not regulate swimming instruction intensity, and thus prior art can not meet the requirement of people.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art exactly, there is provided a kind of simple and reliable for structure, both there is security, interest, be convenient to again learn swim and use, can also the load adjustable swimming servicing unit of convenient adjustment swimming instruction intensity.
For overcoming the deficiencies in the prior art, the utility model takes following technical scheme:
A kind of load adjustable swimming servicing unit, is columned device body after comprising inflation, it is characterized in that: device body front end is provided with front axle and connects suspension ring; Device is provided with the fin of streamlined structure with it, and fin is symmetrical; Device is held after one's death and is provided with tubular axis, and tubular axis is inserted in axle sleeve, and axle sleeve and tubular axis are loose fit and energy flexible rotating; Axle sleeve outer wall is provided with the rotor of wing shapes, tilt adjustable, and rotor becomes streamlined symmetrical on axle sleeve, and rotor outer rim is provided with rotor ring and forms a global facility; Tubular axis is provided with dismountable spiral cover and realizes sealing, and spiral cover is provided with valve.
Described axle sleeve is also provided with adjustable ring axle sleeve, and adjustable ring axle sleeve has spoke connect adjustable ring and form a global facility, global facility can be moved and is locked by forward and backward nut on axle sleeve.
Described suspension ring are provided with kink and realize the connection with front axle, and kink can around front axle flexible rotating.
Described tubular axis is provided with thrust step.
Device body main body generally adopts softer silica gel or plastic material to make, and front end suspension ring and kink are integrated, and kink and front axle are loose fit, and kink can around front axle flexible rotating; The spiral cover of tubular axis afterbody there is valve, opens spiral cover and can pour into water, be also filled with air by valve.
Fin is symmetric(al) flow line style, plays stable guide effect; The similar Airfoil Sections shape in rotor cross section, axle sleeve becomes streamlined symmetrical, rotor torsion fluid flows through aerofoil both sides has significant flow velocity difference to produce different pressure, and thus produce rotary power and make rotor wing rotation, axle sleeve and tubular axis are that loose fit can flexible rotating.
When rotor aclinal (parallel with axle), fluid flows through the pressure that aerofoil both sides do not have current difference to produce, rotor non rotating; When rotor has inclination angle, fluid flows through the pressure that aerofoil both sides have current difference to produce, rotor wing rotation, and inclination angle is larger, rotating speed is faster, the resistance of advance is also larger, thus, the inclination angle of adjustment rotor just effectively can adjust drag size, thus regulates the load of swimming instruction.
When not needing swimming to load, rotor can be allowed to keep natural streamline state (parallel with axle), now lower resistance can draw advance; When needing when swimming to load strengthening physical training, pusher collar produces extruding to rotor and reverses, fixed by forward and backward locking nut, locking extruding at this moment makes tail rotor torsional deflection and generation inclination angle, changes fluid stress, significantly can increase advance resistance again.
When swimming, be blown into air from valve, then penetrate elastic rope by suspension ring and prick and tie up loins, water just can be descended to have swum safeguard protection effect, device can be embraced when fatigue and have a rest in the water surface.
During continuous swimming, axle sleeve and rotor can, at slow circumvolve under flow action, strengthen dynamic and interesting; Kink and front axle are movable loose fit, can discharge the torsion of rope in time; When swimming rate is accelerated; the rotary speed of axle sleeve and rotor is also accelerated thereupon, and resistance increases, and the load of swimmer also strengthens thereupon; thus change swimming rate just can significantly increase suddenly or reduce athletic training strength, this has very positive effect for training a swimmer.
When needs carry out swimming physical training, spiral cover can be opened and pour water, regulate water and the ratio being filled with air, device can be immersed in the water suitable draft when swimming, thus increase advance resistance, make sportsman be in bringing onto load physical training condition, be conducive to strengthening physical efficiency.
Compared with prior art, the beneficial effects of the utility model are also:
Simple and reliable for structure, the ingenious fluid mechanics principle that utilizes makes device rotate, both the safety of swimming had effectively been ensured, strengthen again dynamic and interesting, by pouring water and rotor tilt adjustment training load, also can also be particularly conducive in swimming instruction and significantly increase suddenly or reduce exercise intensity, integrating the several functions such as safe swimming, entertaining, innervation, training, be a kind of very good swimming aid, have a extensive future.
