The utility model content

But the synchronous reciprocation type working system of this trick provides a kind of and lets at high speeds such as bicycle, manual tricycle, pleasure-boat advance or improve the efficient apparatus of load-carrying in order to solve the problems of the technologies described above.The synchronous reciprocation type working system of trick that uses on its simple in structure, easy to use, suitable various people's power cars, small-scale workshops ship, park amusement yacht, body-building apparatus and the family's part simple machine.

Be achieved in that the synchronous reciprocation type working system of a kind of trick in order to address the above problem the synchronous reciprocation type working system of trick, its characteristic is following with structure:

It mainly comprises rocking arm and track support, rocking arm, slider, pedal, ratchet sprockets mechanism, wherein drives slider through rock back and forth rocking arm and push-and-pull pedal and seesaws.

The power that its one side output of the synchronous reciprocation type working system of described trick comes is that the both hands by the people shake rocking arm; rocking arm passes the power of coming and is delivered on the connecting rod to reversing sense by the rocking arm lower semisection through the axle in the middle of the rocking arm again, directly promotes or spur sliding shoe by connecting rod.The opposing party is that both feet are tied up on pedal, directly promotes or retract slider acting, by the ratchet on the chain pulling both sides of slider rear and front end, changes into circular movement by original straight-line motion again, because of the principle of work of ratchet is one-way only operation.When its just and then ratchet rotation of ratchet shaft when the direction of work is drawn by chain passively, the wheel on the bicycle just begins to have rotated thus.If be contained on the ship, just by the next gear of the gear driven on the ratchet shaft, be aggregated on the transmission shaft that connects another ratchet by coaxial crowngear, finally pass on the screw propeller.Another ratchet also is same acting principle.

The car of the synchronous reciprocation type working system of the utility model trick and existing single pedal both feet circular work, ship, the maximum difference of health and fitness facilities are:

It is that trick is moved simultaneously for the synchronous reciprocation type working system of the utility model trick, and push-and-pull all is acting, and pin draws during hand push, and pin pushes away when pulling equally.And not limited by the length of push-and-pull motion amplitude, all transmit the corresponding energy that you pay equally.The comparison of same motion on the theory, an existing common three-wheel vehicle is equipped with trick and also just can draws 400 kilograms goods with the three-wheel vehicle of the device that does work back and forth synchronously as drawing 100 kilograms.

The synchronous reciprocation type working system of the utility model trick simple in structure, manual dexterity, easy to use, improved car and boat, instruments of labour efficient.Changed the sports apparatus that foot fitness equipment mono-leg exercise becomes all-around exercises.

The specific embodiment

Below in conjunction with accompanying drawing the synchronous reciprocation type working system of this practical trick is further specified.

The synchronous reciprocation type working system of a kind of trick, in its when work,, structure as shown in Figure 1 was following: by rocking arm and track support 1, rocking arm 2, slider 3, pedal 4, ratchet sprockets mechanism 5, transmission gear 6, the power driver that seat 7 workpiece such as grade are formed.Wherein rocking arm 2 middle parts are installed in the axle sleeve in the rocking arm upper bracket by a movable axis.Rocking arm 2 lower ends connecting can be movable connecting rod, the other end of connecting rod is connected on the slider 3, track two of slider 3 tightly is locked in rocking arm and track support 1 mullion.In ratchet sprockets mechanism 5, two of chain is installed on the slider, on the same straight line of chain, by chain pulling ratchet, thereby changes job specification before and after two ratchets are installed in respectively, and the straight-line motion by original changes to circular movement.And can connect transmission gear 6, drive the motion of transmission gear 6.

When holding the rocking arm handle push-and-pull rocking arm of rocking arm 2 tops,,, the top changed direction through tween drive shaft so passing the power of coming owing to be installed on the rocker arm support in the middle of the rocking arm 2.The connecting rod of connection rocking arm 2 lower ends push-and-pull passively the slider 3 that is connected in the other end.And chain before and after the pulling, chain pulling ratchet because ratchet is one-way only operation, so two ratchets when rotating, have only one be pulled transmitting energy.

The opposing party's both feet are tied up on pedal 4, and pedal 4 is installed in the both sides of slider 3.Pin pushes away when shaking arm 2 pulling, and this has just in time met people's rule that the instinct lower margin will be pedaled when drawing forward, and when hand propelled rocking arm 2, both feet have made pulling slider 3 into by pushing away.So again and again the repeating motion energy has produced like this.

The synchronous reciprocation type working system of trick is to be bundled on the pedal 4 because of pin only as being installed on the ship.As meet accident, be difficult to free for the moment.So on pedal 4, emergent device for opening can be installed, emergent device for opening is that both feet are firmly outside by the light of nature when meeting accident according to the people.

Pedal 4 can be pressed the height size of instep and regulate, and big adjusting and minor adjustment are arranged, the length of also with good grounds end user's pin and regulate before and after the design-calculated and lock.Seat 7 is regulated before and after also can be up and down.

But it is fixed on said rocking arm and track support 1 on ship or the vehicle, and it is the fulcrum that rocking arm 2 provides an anti-motoricity that axle sleeve is housed in its top shelf.Rocking arm 2 upper semisections are equipped with in the rocking arm grip can be by the device of people's height up-down adjustment.The front and back mullion of rocking arm and track support 1 is that four staies are formed, and two one group, it pins two tracks tightly, and a function is exactly top dead point and the bottom dead point that control slider 3 moves on track again.
