This creation is a kind of waist support band structure,Main system comprising master tape body,Elastic band,Shift(ing) ring,Wheel rim and band combination are constituted,Wherein,The master tape body centre or so sets up several elastic bands separately and concentrates connection what shift(ing) ring,The shifting slip ring is arranged a wheel rim,The external side of what master tape is fixed in the band one end,Band is wound what wheel rim by the other end,Frictional force conference between band and wheel rim promotes wheel rim to rotate around the ring body of shift(ing) ring,And keep shift(ing) ring mobile toward band direction of pull,Elastic band is set to be generated the reaction force of contraction by tension tautness,And band is fixed to each other in front of what user body,And then it generates the master tape body between elastic band and band fixing end and shrinks binding force; Frictional resistance by the wheel rim and mobile interannular is small,Reach can tighten easily master tape body,Improve the practical effect for supporting effect.本創作係一種護腰帶結構,主要係包含主帶體、鬆緊帶、移動環、輪圈及束帶組合構成,其中,該主帶體中央處左右分設數條鬆緊帶並集中連結於移動環,該移滑動環套設一輪圈,該束帶一端固定於主帶體外側,另一端將束帶纏繞於輪圈,束帶與輪圈之間的摩擦力大會促使輪圈繞著移動環之環體旋轉,並使移動環往束帶拉力方向移動,使鬆緊帶受拉力繃緊而產生收縮之反作用力,並將束帶相互固定於使用者身體前方,進而使鬆緊帶與束帶固定端間之主帶體產生收縮束緊力;藉由該輪圈與移動環間之摩擦阻力小,達到可輕易束緊主帶體、提高支持效果之實用功效。
