[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides an elastic reel reel and a rowing machine, which have the following advantages:

[0014] This elastic reel and rowing machine is designed with a reel, a first guide wheel, a pull rope, a high-strength polyester fiber belt, a flywheel, a drive belt, a reel, a double-stroke gas spring, guide wheels, an air pump, an air duct, and a second guide wheel. During use, the air pump controls the air pressure within the double-stroke gas spring. When the high-strength polyester fiber belt is pulled out of the reel, it pulls the two guide wheels closer together. At this time, the piston rod compresses the air in the cylinder. Then, when the reel retracts the high-strength polyester fiber belt, the double-stroke gas spring pushes the guide wheels, pulling the high-strength polyester fiber belt and causing the reel to reverse. The pull rope is then rewound onto the reel. This design ensures that the rewinding force of the reel is not adjustable, allowing for adaptation to different training intensities and improving practicality. Attached Figure Description

During operation, the air pump 12 controls the air pressure within the double-stroke gas spring 10. When the high-strength polyester fiber belt 6 is pulled out of the take-up device 9, it pulls two guide wheels 11 closer together. At this time, the piston rod compresses the air in the cylinder. Then, when the take-up device 9 retracts the high-strength polyester fiber belt... When the belt 6 is in operation, the double-stroke gas spring 10 will push the guide wheel to pull the high-strength polyester fiber belt 6 and pull the take-up wheel 3 to reverse. At this time, the pull rope 5 will be rewound onto the take-up wheel 3, thus achieving the effect of the take-up force of the take-up device 9 being mostly non-adjustable, so as to adapt to different intensity training modes and have better practicality. The upper surface of the frame 1 is slidably equipped with a seat cushion 15, and the outer wall surface of the air duct 13 is equipped with an air pressure monitor.

When the high-strength polyester fiber belt 6 is pulled out of the reel 9, it pulls two guide wheels 11 closer together. At this time, the piston rod compresses the air in the cylinder. Then, when the reel 9 retracts the high-strength polyester fiber belt 6, the double-stroke gas spring 10 pushes the guide wheel to pull the high-strength polyester fiber belt 6, causing the reel 3 to reverse. The pull rope 5 then rewinds onto the reel 3. This design ensures that the rewinding force of the reel 9 is mostly adjustable, allowing for adaptation to different training intensities and improving practicality.
