Description

Without the need to the exercycle of counterweight

Technical field

The utility model relates to field of exercise equipment, refers to a kind of exercycle without the need to counterweight especially.

Background technology

Exercycle is a kind of aerobic fitness equipment of simulating outdoor exercises, according to the theory structure of bicycle, is got up by flywheel fixed mount, and arrange counterweight on flywheel, by trampling the flywheel of this " bicycle " drive through counterweight, realizes simulation outdoor exercises.But there is a series of defect in this exercycle, flywheel can provide larger moving loads for user at the driving initial stage, but after flywheel drives completely, its inertia will order about flywheel and automatically rotate, and then greatly alleviate the moving loads of user, and flywheel turns get up after speed very fast, also can form potential safety hazard, need a casing to be encapsulated, in addition, exercycle weight after flywheel counter weight is large, is inconvenient to move, is therefore unfavorable for that common house uses.

Utility model content

The purpose of this utility model is to provide a kind of exercycle without the need to counterweight, its technical problem to be solved is: traditional exercycle utilizes the gravity of flywheel to be used as the moving loads of user, after the rotating speed of flywheel own is mentioned, flywheel is autobiography under effect of inertia, user does not reach motion exercise effect, and weight large, there is potential safety hazard.

For solving the problems of the technologies described above, the utility model provides a kind of exercycle without the need to counterweight, and it comprises fixed pedestal, vehicle frame, front crankshaft and rear bent axle, described vehicle frame by described front crankshaft and afterwards crankshaft installed on described fixed pedestal;

Described fixed pedestal comprises mounting and feet, described mounting is respectively arranged with front axle bore and rear axle bore that central shaft is parallel to each other, and convex section of the song of described front crankshaft and rear bent axle is located in described front axle bore and rear axle bore respectively;

Described vehicle frame comprises the triangle-frame that two have common side rod, two described triangle-frames with common side rod lay respectively on two intersecting planes, after being formed between two drift angles corresponding with described common side rod respectively on described two triangle-frames, bent axle is pitched, two drift angles corresponding with described common side rod respectively on described two triangle-frames are provided with rear axle housing, and the two ends of described rear bent axle are rotating to be respectively located in two described rear axle housings; One end on described common side rod is pitched corresponding opposite side with described rear bent axle and is fixedly installed cushion, the other end of described common side rod is pitched identical side to be fixedly connected with a front crankshaft to pitch with described rear bent axle, two prongs of described front crankshaft fork are respectively arranged with front shaft sleeve, the two ends of described front crankshaft are rotating to be respectively located in two described front shaft sleeves, and on the fork handle of described front crankshaft fork, the side of corresponding described cushion is provided with handrail;

The two ends described rear bent axle being piercing in respectively two described rear axle housings are respectively arranged with pedal crank.

Be preferable over: described fixed pedestal and vehicle frame all adopt the tubing of steel or aluminium alloy matter or carbon fibre materials.

Compared with prior art, the beneficial effects of the utility model are: user can be sitting on cushion and trample pedal crank, and then the plane throwing that the relative fixed pedestal support user of vehicle frame itself can be driven to do is up and down moved, the weight of user itself not only can be utilized as moving loads, sports fun can also be provided for user, and need not extra counterweight, conveniently transport, remove and move.
