Star-wheel-shaped load-adjustable weightlifting training device

Abstract

The invention discloses a star-wheel-shaped load-adjustable weightlifting training device. A stand column is fixed on the ground; a load traveller is positioned and supported by a pin roller to flexibly move up and down in the stand column; the front of the load traveller is connected with a lifting handrail; the travel of the lifting handrail is decided by the opening range of the front of the stand column; a rack is mounted on the back of the load traveller and drives a gear shaft; the gear shaft is in key connection with a star wheel to form a whole body; the star wheel, a steel cylinder and a resilient strip are combined to form a unidirectional gear driven by a unidirectional transmission mechanism. In the star-wheel-shaped load-adjustable weightlifting training device disclosed by the invention, the star-wheel-shaped unidirectional transmission mechanism is used to substitute a barbell to act on the training functions of loaded lifting, no-load putting down, no-load squat and loaded standup and can improve the safety performance; the inertia load and the adjustable friction load are used to substitute a heavy barbell disk, so that the equal loaded training effect is achieved, and meanwhile the load is diversified; the dynamic rotation of a flywheel brings about enjoyment; the star-wheel-shaped load-adjustable weightlifting training device is obvious in practical value and application prospect in the market.

Description

technical field [0001] The invention relates to a load-adjustable weight-lifting training device with a star wheel-shaped one-way transmission mechanism. Background technique [0002] Weightlifting is a training method often used by athletes. Its main purpose is to train the strength and coordination of the upper limbs. Most of the weightlifting training now uses barbells. Barbells are a classic and traditional weightlifting training equipment. Because they are simple, durable and easy to operate Therefore, it has become a first-selected equipment for training lifting and squatting, but because it is bulky and easy to cause accidental injuries and rigid in form, although it is an effective training equipment, it is still daunting and has certain safety hazards. [0003] On the other hand, since the addition or reduction of the barbell plate needs to be disassembled, it is relatively cumbersome, which is not conducive to convenient and quick adjustment of the load and trainin...

[0002] Weightlifting is a training method often used by athletes. Its main purpose is to train the strength and coordination of the upper limbs. Most of the weightlifting training now uses barbells. Barbells are a classic and traditional weightlifting training equipment. Because they are simple, durable and easy to operate , thus become a kind of equipment of choice for training lifting and squatting, but because of its bulky and easy to cause accidental injuries and rigid form, although it is an effective training equipment, it is still daunting, and there are certain safety hazards

[0003] On the other hand, since adding or reducing the barbell needs to be disassembled, it is relatively cumbersome, which is not conducive to convenient and quick adjustment of load and training intensity
