Technical Field

[0001] This invention relates to the field of bodybuilding training technology, specifically to a teaching device for assisting in posture correction in aerobics. Background Technology

[0002] Aerobics is a popular and widely enjoyed sport that combines gymnastics, dance, music, fitness, and entertainment. During the aerobics learning process, practitioners usually observe their own practice through a mirror and make timely improvements to any shortcomings.

[0003] For example, application number CN201711278624.X: This invention provides a training device for aerobics, including a leg press bar, a lumbar pillow, a lumbar pillow positioning ring, a lower back support rod, an adjusting nut, support rails, a grip, and a main support rod. The vertical track on the right side extends outward and protrudes, and is welded and fixed to the inverted support plate in the middle. Four lower back training devices are sequentially supported and welded from left to right on the top of the left base plate. Each of these four lower back training devices includes a lumbar pillow, a lumbar pillow positioning ring, four lower back support rods, an adjusting nut, two support rails, and a grip. The four lower back support rods are arranged symmetrically in two groups, and two symmetrical support rails are horizontally and symmetrically welded to the two lower back support rods on the inner side. A grip is connected between these two support rails. A layer of padded sponge is provided on the top of the shoulder plate. The fixing plate of this invention can support and reinforce the two inverted support plates on the left and right sides, preventing the inverted support plates from tipping over upon impact with the body.

[0039] When the present invention is used, the sliding plate and the fixed plate are attached together, the contrast mirror folding top block is inserted into the contrast mirror folding top groove, and at the same time the contrast mirror folding top block pushes the contrast mirror trigger rod backward, causing the side contrast mirror to swing forward, thereby realizing the folding of the side contrast mirror.

[0040] This invention allows trainees to observe the side view without moving their heads, correct their posture in real time, ensure training effectiveness, and achieve good learning results.

[0081] Working principle: During use, the trainee trains on the folding training platform 3. Light from the trainee's left and right sides is first reflected by the side reflector 5, and then enters the trainee's eyes through the side contrast mirror 4. The trainee can observe the side view without moving their head and correct their posture in real time to ensure training effectiveness. When folding, the folding training platform 3 is flipped forward and pushed backward. The three-stage scissor mechanism composed of the sliding connecting rod 6 deforms. The sliding connecting rod 6 drives the connecting rod slider 601 to slide left and right. The connecting rod slider 601 drives the intermediate transmission component 7 to rotate through the gear and rack transmission mechanism composed of the intermediate driven gear 701 and the reflector active rack 602. The intermediate transmission component 7 drives the reflector folding sliding block 8 to slide left and right through a gear and rack transmission mechanism consisting of the reflector driven rack 802 and the intermediate transmission drive gear 702. The reflector folding sliding block 8 drives the side reflector 5 to flip through a crank-slider transmission mechanism consisting of the reflector folding sliding block 8, the reflector folding connecting rod 801, the side reflector 5, and the sliding plate 2, thereby realizing the automatic folding of the side reflector 5. When the sliding plate 2 is attached to the fixed plate 1, the contrast mirror flipping top block 201 is inserted into the contrast mirror folding top groove 102. At the same time, the contrast mirror flipping top block 201 pushes the contrast mirror trigger rod 401 backward, causing the side contrast mirror 4 to swing forward, thereby realizing the folding of the side contrast mirror 4.
