Abdominal muscle wheel lubricating structure

Abstract

The invention discloses an abdominal muscle wheel lubricating structure, and belongs to the technical field of sports equipment and devices. An abdominal muscle wheel comprises a rolling wheel (3) and handles (1) arranged on the two sides, wherein the rolling wheel (3) and the handles on the two sides are connected through rolling bearings (2). A main oil path (4) is formed over the rolling wheel (3), the inlet of the main oil path (4) is formed in the upper surface of the rolling wheel (3), and a telescopic oil pipe (5) is arranged in the main oil path (4). The inlet of the main oil path (4) is arranged in the middle of the interior of the rolling wheel (3), the main oil path (4) is divided into a plurality of branch oil paths (6), and the outlets of the branch oil paths (6) are formed over the rolling bearings (2). The abdominal muscle wheel lubricating structure is simple in structure and can lubricate the bearings at the joints of the rolling wheel and the handles, the training effect can be ensured, and meanwhile the service life of the abdominal muscle wheel can be prolonged.

Description

technical field [0001] The invention relates to an abdominal muscle wheel, in particular to an abdominal muscle wheel lubrication structure, which belongs to the technical field of sports equipment. Background technique [0002] The abdominal muscle wheel is a kind of equipment for exercising the body. The type is like a medicine grinder. When exercising, kneel on the ground, hold the handle with both hands, and place the abdominal muscle wheel on the front of the body, so that you can focus on using the strength training of the abdominal muscles, and it is not easy to use force to reduce the pressure on the lower back. [0003] The existing abdominal muscle wheel is composed of a roller in the middle and handles on both sides. The structure is relatively simple. Among them, the roller and the handle rotate through bearings. Long-term use will cause poor rotation of the bearings due to wear and tear, and most The roller wheel and the handle in the abdominal muscle wheel ar...

[0003] The existing abdominal muscle wheel is composed of a roller in the middle and handles on both sides. The structure is relatively simple. Among them, the roller and the handle rotate through bearings. Long-term use will cause poor rotation of the bearings due to wear and tear, and most The roller and the handle in the abdominal muscle wheel are fixedly installed and cannot be lubricated, which affects the effect of exercise and reduces the service life of the abdominal muscle wheel
