Cord adjustment buckle

Abstract

The invention discloses a cord adjustment buckle. A wire wheel is contained in a containing groove in the substrate; a plurality of first clamping teeth are arranged on the circumference of a shaft portion of a bottom portion of a containing groove in an annular manner; a top of a wire wheel main body which is pivoted on the shaft portion is provided with a plurality of second clamping teeth which are arranged in an annular manner; a rope is arranged in a coiling groove on the circumference of the main body; a shaft column which is connected to the shaft portion passes through a connection seat of a one-way clutch mechanism; a plurality of third clamping teeth are meshed with the second clamping teeth on the bottom of the connection seat; a plurality of fourth clamping teeth which are meshed on the first clamping teeth are arranged on the bottom of the shaft column; a plurality of brake portions on the circumference of the shaft colum accomodate a planetary gear meshed with the top of the connection seat; a rotation plate covers the outside of the connection seat, such that the rotation plate drives the connection seat to rotate and the wire wheel is in linkage to retract and tie up a role, or the rotation plate is lifted and the connection seat is seperated from the wire sheel in order to unlock and pull out the rope /

Description

technical field [0001] The invention relates to a rope adjustment buckle, especially refers to a shaft in a housing groove of a seat body on which a wire wheel is pivotally connected, and the shaft is connected with a shaft column through which a one-way clutch mechanism passes through the connecting seat. It can be pulled on the turntable combined with the outer cover of the connecting seat, and linked to the reel to wind up the tight rope, or the turntable can be pulled up to unlock and pull out the rope. Background technique [0002] Nowadays, sports are popular, regardless of men, women, old and young, and all ages, regular exercise can improve cardiorespiratory capacity, muscle endurance, promote metabolism, enhance immunity, and help relieve stress and improve the quality of life. Running , Cycling, cycling picnic and other sports need to move or step on the feet, and the weight of the body is borne by the feet. In order to improve the exercise effect and train the fun...

Problems solved by technology

[0004] However, in order to solve the problem of tripping or accidents caused by the exposed shoelaces of the shoe body, some manufacturers have developed a rope-adjustable buckle that does not need to tie the shoelaces, which uses a knob to drive a one-way ratchet mechanism To roll up and tighten the rope, and adjust the tightness of the shoe mouth by matching the rope with the buckle on the upper corresponding to the tongue. However, most of the one-way ratchet mechanisms of this kind of rope-adjustable buckle use shrapnel , the operation sound will be produced when the knob is turned, and when the rope is pulled in the opposite direction by an external force, it will easily cause the one-way ratchet mechanism to be over-stuck and difficult to unlock, and at the same time affect the stability and smoothness of the overall operation, and even lead to a failure rate Improvement and damage, how to solve the above problems is the direction to be studied and improved by those who are engaged in this industry
