An airbag-type running weight-bearing device that uses the end face to adjust the load

Abstract

The invention discloses an airbag running weight device allowing end face assisted load adjustment. The airbag running weight device a rubber roller and tube shafts disposed at two ends of the rubber roller. The outer surface of the rubber roller is provided with cylindrical non-slip teeth; an airbag is disposed within the rubber roller; two end faces of the airbag are provided with bristles by embedding; the airbag is hermetically integrated to the tube shafts through two end plates on two sides; two ends of the tube shafts are connected with the end plates through bearings; a bearing block bore of each end plate and a bearing outside thereof are in clearance fit; when the airbag is expanded with compressed air, the tube shafts drive the bearings to move in the bearing blocks of the end plates, and the end plates and the rubber roller are fixed to form a roller assembly flexibly rotatable; one end of each tube shaft is provided with a nozzle communicated with the airbag. By make ingenious use of the pneumatic expansion of the airbag to adjust contact pressure of the bristles and the inner surfaces of the end plates, a running weight is adjusted; end face contact allows convenience for flexible adjustment of the load; the structure is simple and ingenious, the diversified weight running training needs are met, and the application prospect is promising.

Description

technical field [0001] The invention relates to a load-adjustable running load-bearing device, in particular to an airbag-type running load-bearing device that uses an end face to adjust the load. Background technique [0002] Weight-bearing running is one of the commonly used physical training methods, which can exercise the lower limbs well, enhance the endurance of physical fitness and the tolerance of the body. The most commonly used equipment for weight-bearing running is the tire, that is, the tire is tied with a rope to run around the waist. Due to the friction between the tire and the ground, the runner must overcome the frictional resistance to move forward, so as to train the body's endurance and endurance. power purpose. [0003] Due to the rigid dragging form of the tires, it is not convenient to adjust the frictional resistance with the ground, so the runner's load cannot be adjusted conveniently and quickly, and the diversified physical training needs cannot b...

Problems solved by technology

[0003] Due to the rigid dragging form of the tires, it is not easy to adjust the frictional resistance with the ground, so it is not convenient and quick to adjust the runner's load, and it cannot meet the diverse physical training needs.
