Abdominal muscle exercise device

Abstract

The invention discloses an abdominal muscle exercise device. The abdominal muscle exercise device comprises a rack, tracks which are arranged on the two sides of the rack, a dual-roller mechanism, protection supports and pedals, wherein the dual tracks are respectively and fixedly arranged on the left and right sides of a bed frame; the dual-roller mechanism consists of dual rollers, a roller shaft, dual bearings and gripping sleeves, the dual bearings and the dual rollers are respectively installed at the two ends of the roller shaft, the distance between the dual rollers corresponds to the distance of the dual tracks, the dual rollers can roll along the dual tracks and the dual gripping sleeves are fixedly arranged on the roller shaft; elongated slots are symmetrically arranged in the dual protection supports, and the dual bearings at the two ends of the roller shaft are respectively arranged in the elongated slots and can slide in the elongated slots; the dual pedals are symmetrically and fixedly arranged in the direction of the other end of the bed frame. The abdominal muscle exercise device has the advantages that the device is safe and reliable, the service life is longer, the exercise intensity is improved and more parts of human bodies can be fully exercised.

Description

technical field [0001] The invention relates to an abdominal muscle exerciser, in particular to an abdominal muscle exerciser suitable for both indoors and outdoors. Background technique [0002] Along with the needs of people to improve the quality of life, strengthen physical activity, the desire of enhancing physical fitness is higher and higher, and various sports are popularized and popularized day by day. Strengthening the muscle training of various parts of the human body is an important means to maintain a healthy body and enhance human strength. In order to exercise the abdominal muscles, someone has invented a simple unicycle abdominal muscle exerciser. This single-wheel abdominal muscle exerciser is easy to operate and easy to operate. Just kneel on the ground, hold the wheel shaft with both hands, rely on the strength of the waist, abdomen and arm muscles to make the single wheel roll back and forth on the ground, and the human body is stretching and shrinking. ...

AI Technical Summary

Problems solved by technology

There are mainly deficiencies in the following aspects in the abdominal muscle exerciser of this structural form: the one, there is potential safety hazard

Because the exerciser adopts the single-wheel form, during the exercise, the athlete always keeps his head facing the single-wheel. If he accidentally exerts too much force or exercises for a long time and causes fatigue, his chin will easily hit the middle of the exerciser. the unicycle, which inflicts damage

Second, the deformation of the metal plate affects the service life of the exerciser

Because the metal plate on the frame bears the pressure and friction of the single wheel for many years, the metal plate will be deformed when it is in disrepair for a long time. Deviation occurs in the center, causing the entire exerciser to be scrapped
