Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to an abdominal exercise device. Background Art

[0002] Chinese patent document with publication number CN218980363U discloses a double-wheel elbow support ab wheel, which includes a connecting frame, wheels and a support rod. The wheels are two and are arranged on the front and rear sides of the connecting frame, and the bottoms of the two wheels are in the same plane. The support rod is U-shaped, and the two sides of the inner wall of the opening of the support rod are connected to the left and right sides of the connecting frame; elbow support members are arranged on both sides of the outer wall of the opening of the support rod. By placing the elbows on the elbow support members and holding the support rod with hands, abdominal exercise can be started. Therefore, through the arrangement of the two wheels, the overall operation is more stable. Secondly, the arrangement of the elbow support members increases a point of force. Therefore, during exercise, the strength of the arm can be reduced and the force can be transferred to the elbows, thereby reducing the exercise difficulty, and even beginners can do it more easily. This solution also specifically discloses that: the wheels are provided with mounting rods, and both ends of the mounting rods are connected to the connecting frame. An elastic member for increasing resistance is sleeved outside the mounting rod. One end of the elastic member is connected to the inner wall of the wheel, and the other end of the elastic member is connected to the mounting rod. Both ends of the elastic member expand as the wheel rotates counterclockwise and compress as the wheel rotates clockwise. Through the arrangement of the elastic member and by allowing the elastic member to cooperate with the rotation of the wheel to change the elastic force, the force on the wheel is balanced.

[0003] However, the above solution cannot change the elastic force of the elastic member, and the resistance of the elastic member to the forward sliding of the ab wheel and the boost force to the backward sliding of the ab wheel cannot be controlled, so the controllability is poor. Moreover, during long-term use, the elasticity is likely to be damaged due to friction. Summary of the Utility Model
