Multifunctional physical fitness lower limb strength training equipment

Abstract

A piece of multifunctional physical fitness lower limb strength training equipment comprises a base, a lying plate is fixedly installed on one side of the top side of the base through stand columns, the lower end of the lying plate is fixedly connected with the lower end of one side of a seat plate, and the front end and the rear end of the upper end of the seat plate are fixedly connected with the lower ends of polished shafts respectively, the peripheries of the polished shafts are slidably sleeved with sliding sleeves respectively; The adjacent sides of the sliding sleeves are fixedly connected through a transverse plate; a box is fixedly installed on the other side of the top side of the base through stand columns, a movable water tank only capable of moving vertically is slidably installed in the box, the top side of the movable water tank is open, a first fixed pulley is fixedly installed on one side of the top of the box, and a second fixed pulley and a third fixed pulley are fixedly installed on the upper and lower sides of the right side of the box in sequence. The equipment is simple in structure and ingenious in conception, water is used for replacing dumbbell pieces, the cost is greatly reduced, meanwhile, the load can be steplessly adjusted, different requirements are met, the load can be automatically and circularly changed, and therefore the situation that one more load is used for exercise for a long time, and the muscle activity is improved is avoided.

Problems solved by technology

[0002] Lower limb strength training is the basic training of physical fitness training. In order to increase the intensity of lower limb strength training, weight training is generally used, and the reverse pedal is the equipment used for lower limb strength weight training; but the load of the reverse pedal is generally to use dumbbell plates. Adjusting the load size is cumbersome, the price of the dumbbells is high, and the input cost is increased, and the dumbbells are replaced frequently, which causes great wear and tear on the equipment, and the quality of the dumbbells is fixed, so the load cannot be adjusted steplessly. At the same time, in order to reduce the replacement frequency of the dumbbells , when exercising directly with a large load, it will lead to inability to warm up effectively, or forget to warm up and exercise directly, which will cause great damage to the body and cannot meet the actual needs. Therefore, we have invented a multi-functional sports lower limb strength training equipment.
