Claw-wheel-shaped load-adjustable weightlifting training device

Abstract

The invention discloses a claw-wheel-shaped load-adjustable weightlifting training device, wherein a stand column is fixed on the ground; a load sliding column can flexibly move up and down in the stand column by being located and supported by a rolling column; the front of the load sliding column is connected with a lift-holding handle, and the stroke of the lift-holding handle is decided by the range of an opening of the front of the stand column; a rack is arranged on the back of the load sliding column, and a one-way claw gear shaft is driven by the rack; one-way claw matching transmission is adopted between the one-way claw gear shaft and a one-way claw gear. According to the claw-wheel-shaped load-adjustable weightlifting training device, the training functions of lifting the weight loaded on a barbell and no-load putting down as well as no-load squatting and load standing up are ingeniously replaced by the clutch transmission way of positive clamping transmission and reverse sliding separation generated by a one-way claw gear transmission mechanism, so that the safety is improved; heavy discs of the barbell are replaced by inertia load and adjustable friction load, so that the same load training effect is achieved; furthermore, the loading has diversity, dynamic property and interestingness, so that the device has remarkable practical value and market application prospect.

Description

technical field [0001] The invention relates to a load-adjustable weight-lifting training device with a claw 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
