A primary abdominal health equipment

Abstract

The invention discloses a primary abdominal strengthening device, which comprises a flat plate embedded on the ground, a central groove and two inclined grooves are arranged on the upper end of the flat plate, and the two inclined grooves are distributed symmetrically about one central groove, and one A center roller is rollingly connected to the center groove, and a straight rod is rotatably connected to the center roller using a first bearing. Both ends of the straight rod are symmetrically and fixedly connected to an oblique rod. The groove line is vertical, and each of the inclined rods is rotatably fitted with an inclined roller using a second bearing. The second bearing includes an inner ring and an outer ring that are concentrically distributed inside and outside, and the sides of the two inner rings that are far away from each other are fixedly connected There is a sleeve, the outer surface of which is spline-slidably fitted with a grip sleeve. The advantages are: the invention is suitable for primary abdominal exercisers to gradually adapt to the exercise intensity to achieve the purpose of step-by-step exercise. In addition, it brakes automatically when physical strength is exhausted or other situations occur, so as to improve the safety of use.

Description

technical field [0001] The invention relates to the technical field of physical exercise, in particular to a primary abdominal strengthening device. Background technique [0002] The abdominal wheel is a small pusher that can exercise muscles, joints, and reduce weight. There are various training methods for using the abdominal wheel. The current abdominal wheel generally includes two handles and a rotating handle installed between the two handles. The structure of the rolling wheel is too simple, and there are the following disadvantages: when the exerciser uses the abdominal wheel, because the rolling wheel has no established track, the rolling wheel may gradually shift when the rolling wheel is pushed, causing the body to bend, which cannot achieve the desired effect. exercise effect, and because the abdominal wheel is not equipped with a braking device, the exerciser's physical strength is insufficient or under the influence of other conditions, the speed is too fast and...

[0002] The abdominal wheel is a small pusher that can exercise muscles, joints, and reduce weight. There are various training methods for using the abdominal wheel. The current abdominal wheel generally includes two handles and a rotating handle installed between the two handles. The structure of the rolling wheel is too simple, and there are the following disadvantages: when the exerciser uses the abdominal wheel, because the rolling wheel has no established track, the rolling wheel may gradually shift when the rolling wheel is pushed, causing the body to bend, which cannot achieve the desired effect. Exercise effect, and because the abdominal wheel is not equipped with a braking device, the speed of the exerciser is too fast and muscle strain occurs under the influence of the exerciser's physical strength or other conditions, which poses a safety hazard
