Adjustable and controllable strength trainer characterized by pulling weight during half-squat and stand

Abstract

The invention belongs to the field of sports equipment, and relates to an adjustable and controllable strength trainer characterized by pulling a weight during half-squat and stand. The strength trainer is characterized in that a shock-reducing rubber blanket is placed on the ground; a weight is placed on a shock-reducing rubber blanket; inner sides of four pulling handles are welded and connected onto the outer side of the lower end of an up-lifting rack; four castors are hinged at the lower end of the up-lifting rack through four shafts respectively and placed on the ground; a first rubber blanket is pasted and connected with the upper middle part of the weight; weight scale values corresponding to the weight are engraved on the up-lifting rack; the lower part of the up-lifting rack is placed on the first rubber blanket; a second rubber blanket is fixedly connected onto the inner upper side of a sliding sleeve through a rivet; the sliding sleeve is buckled on the up-lifting rack; and the two sides of the sliding sleeve are fastened and connected with the weight through four screws. Suitable pulling weight can be found out through moving the up-lifting rack forwards and backwards, so that the problem that the conventional pulling weight is not easy to adjust and control can be solved; when the trainer is used during the process of squat and stand, the muscles of lower limbs are in the state of isotonic contraction; and the pulling handles are arranged at the two ends of the trainer to enable training at either end to be realized conveniently.

Description

technical field [0001] The invention belongs to the field of sports equipment, and relates to a strength training device capable of adjusting half-squat, standing-up, and lifting weights. Background technique [0002] Practicing half squats, standing up and lifting heavy objects with both hands has the effect of developing the muscle strength of the upper and lower limbs. There are the following problems in the current strength exercise of lifting heavy objects with both hands while squatting: a. The process of lifting the barbell with an appropriate weight and disassembling and assembling the barbell is time-consuming and laborious; b. It is not easy to find the weight that suits you; c. Lifting electronic scales can easily display the force value of lifting, but because the lower limbs cannot stand up, long-term isometric muscle contraction is not conducive to the development of muscle elasticity. Finally, as mentioned above, it is a problem that needs to be solved in the...

AI Technical Summary

Problems solved by technology

[0004] Compared with the previous lifting weight method mentioned in the above-mentioned background technology, the beneficial effects of this exerciser are: a. Moving the lifting frame back and forth can easily find out the lifting weight suitable for oneself, which solves the problem that the lifting weight is difficult to control in the past ; b. When using the exerciser to squat and stand up, the muscles of the lower limbs work as isotonic contraction, which is conducive to the development of muscle elasticity and avoids the situation that the isometric contraction of the lower limbs does not stand up for a long time and affects the muscle elasticity. ; c. The two ends of the exerciser are equipped with lifting handles, which can facilitate the exercise at any end
