Embodiment Construction

[0019] Now in conjunction with accompanying drawing, the present invention is described in further detail.

[0020] Such as figure 1 and figure 2 The airbag-type running load-bearing device that utilizes the cylindrical surface to adjust the load is shown, including a rubber roller 1 and a tube shaft 3, the outer surface of the roller is provided with sickle-shaped anti-skid teeth 9, and the cylindrical airbag 8 is arranged inside the roller 1, and the airbag 8 is planted on the cylindrical surface. There is a brush 7; the tube shaft 3 communicates with the air bag 8 through the air hole 6, the air bag 8 is connected to the tube shaft 3 through the end plates 2 on both sides to form a sealed body, the two ends of the tube shaft 3 are connected to the end plate 2 through the bearing, and the end plate 2 It forms a flexible rotation connection with the rubber roller 1, and an air nozzle 5 is installed at one end of the pipe shaft 3.

[0021] Described pipe shaft is equipped w...

Abstract

The invention discloses an air bag type running load bearing device using a cylindrical surface to adjust load. The air bag type running load bearing device comprises a rubber roller and a tube shaft. Sickle-shaped antiskid teeth are disposed on the outer surface of the roller. A cylindrical air bag is disposed in the roller. Bristles are planted on the cylindrical surface of the air bag. The tube shaft is communicated with the air bag through an air hole. The air bag is integrated with the tube shaft in a sealed manner through end plates on two sides. Two ends of the tube shaft is connected with the end plates through bearings. The end plates and the rubber roller are in flexible rotation connection. An air tap is mounted at one end of the tube shaft. The air bag type running load bearing device has the advantages that inflation expansion of the air bag is ingeniously used to adjust the contact pressure between the bristles and the inner wall of the rubber roller so as to adjust running load bearing, and running load bearing can be increased to the maximum extent due to the fact the bristles are in cylindrical surface contact friction with the roller; the device is simple and ingenious in structure, capable of satisfying diversified running load bearing training requirements, and promising in application prospect.

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 a cylinder 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 be...
