Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings 1-3, but it should be understood that the scope of the present invention is not limited by the following detailed description.

As shown in fig. 1 to 3, the aerobics pedal provided by the present invention comprises a first supporting plate 3, two ends of the lower part of which are connected with a supporting seat 1, the upper side of the first supporting plate 3 is provided with a first accommodating groove 8, and the lower side is provided with a second accommodating groove 9; the pedal 12 is arranged in the first accommodating groove 8, a plurality of guide posts 7 are uniformly distributed and connected on the bottom surface of the pedal 12, through holes 15 matched with the guide posts 7 are formed in the bottom surface of the first accommodating groove 8, and the lower ends of the guide posts 7 penetrate through the through holes 15 and extend into the second accommodating groove 9; bellows 4 sets up in first holding tank 8, and its upper end is connected with footboard 12, and the lower extreme is connected with the lower inner wall of first holding tank 8, and bellows 4 intercommunication has connecting pipe 5, and the one end of connecting pipe 5 is connected with first choke valve 6.

First choke valve 6 selects the choke valve that forward flow is big, reverse flow is little, when pushing down footboard 12, bellows 4 has certain cushioning effect to the footboard, and simultaneously, footboard 12 compresses bellows 4, discharge the gas in bellows 4 from connecting pipe 5, bellows 4 has elasticity and bounces footboard 12, at this moment, gas gets into bellows 4 through connecting pipe 5 from the external world, under the effect of first choke valve 6, the gas flow that gets into bellows 4 is less than the gas flow of following the gas of bellows 4 exhaust, reduce the elasticity that bellows 4 bounced footboard 12, reduce the injury of bounce to training person's knee.

Further, the lower end of the guide post 7 is connected with a sealing gasket 14, a first air bag 11 is arranged in the second accommodating groove 9, and the first air bag 11 is communicated with the through hole 15.

When the pedal 12 is pressed down, the guide post 7 moves downwards along with the pedal, the guide post 7 is connected with the sealing washer 14 to extrude air in the through hole into the first air bag 11, and the first air bag 11 is made of elastic materials and plays a role in buffering the downward movement of the guide post 7.

Further, the lower side of the first supporting plate 3 is connected with a second supporting plate 2, the lower side of the second supporting plate 2 is connected with the supporting seat 1, and the first air bag 11 is arranged on the second supporting plate 2.

The space between the second support plate 2 and the first support plate 3 is limited, and the vertical direction of the first air bag 11 can be limited from increasing, thereby enhancing the buffering effect.

Further, the lower extreme in the through-hole 15 is provided with second choke valve 16, second choke valve 16 includes solid fixed ring 17, its and through-hole 15's inner wall connection, gu fixed ring 17 internal fixation is connected with casing 18, first gas pocket 19 has been seted up to the upper wall of casing 18, second gas pocket 22 has been seted up to the lower wall, be provided with sealing block 20 in the casing 18, third gas pocket 21 has been seted up to the upper surface of sealing block 20, be connected with elastic component 23 between the lower extreme of sealing block 20 and the casing 18 inner wall, elastic component 23 selects the spring.

When a person steps on the pedal 12 to move the guide post 7 downwards, the air in the through hole 15 pushes the sealing block 20 to compress the elastic member 23 to move downwards, air can simultaneously pass through the gap between the sealing block 20 and the shell 18 and the third air hole 21 to enter the first air bag 11, when the person moves away from the pedal 12, the air in the first air bag 11 pushes the guide post 7 to move upwards under the action of air pressure, at the moment, the air pressure pushes the sealing block 20 to seal the first air hole 19, and the air can only pass through the third air hole 21, so that the force for pushing the guide post to move upwards is reduced, the speed of the pedal 12 moving upwards is reduced, and the injury to the knees of the trainer caused by the rebounding of the pedal 12 is reduced.

In order to further improve the buffering effect, the guide post 7 is arranged to be of a cavity structure, the corrugated pipe 4 is connected with the upper end of the cavity of the guide post 7 through the connecting pipe 5, the lower end of the guide post 7 is communicated with the hose 13, the other end of the hose 13 penetrates through the fixing ring 17 to be connected with the second air bag 10, the second air bag 10 is arranged in the second accommodating groove 9, and the second air bag 10 is arranged in the first air bag 11.

The second airbag 10 is arranged in the first airbag 11, and the two airbags can mutually play a role of buffering under the action of air pressure.

Further, a first throttle 6 is arranged in the cavity of the guide post 7, and the structure of the first throttle 6 is the same as that of the second throttle 16.

Principle of operation

When the aerobics pedal provided by the invention is used, a person steps on the pedal 12 to move the pedal 12 downwards, the pedal 12 rebounds under the action of the corrugated pipe 4, meanwhile, gas in the corrugated pipe enters the second air bag 10 through the hose, the second air bag 10 is made of elastic material and has a buffering effect and a compression effect on the gas, the gas returns to the extrusion corrugated pipe 4, the flow rate is reduced under the action of the first throttling valve 6 during returning, the rebounding force of the pedal 12 can be reduced, meanwhile, the guide post 7 connected to the bottom of the pedal 12 extrudes the gas in the through hole 15 into the first air bag 11, and similarly, the gas in the first air bag 11 pushes the guide post 7 to move upwards, meanwhile, the air pressure pushes the sealing block 20 in the second throttling valve 16 to seal the first air hole 19, and the gas can only pass through the third air hole 21, so that the force for pushing the rebounding guide post to move upwards is reduced, the speed for reducing the injury to the knees of a training person when the pedal 12 is used.

In summary, the corrugated pipe is connected between the pedal and the first supporting plate, the corrugated pipe has the damping function, and meanwhile, the first throttle valve is arranged to control air outlet and air inlet of the corrugated pipe, so that the air inlet flow of the corrugated pipe is smaller than the air outlet flow, the elasticity for returning the pedal to the original position is reduced, and the injury to the knees of a trainer is reduced.

The above disclosure is only for the preferred embodiments of the present invention, but the embodiments of the present invention are not limited thereto, and any variations that can be considered by those skilled in the art are within the scope of the present invention.
