Shoelace retracting and releasing device

Abstract

The invention provides a shoelace retracting and releasing device, comprising a wheel, a knob device, a stop device and a non-return disc, wherein the wheel is used for winding, the knob device is in transmission connection with the wheel, the stop device is arranged between the wheel and the knob device; when the knob device is pressed, the wheel and the non-return disc are both locked with the knob device, the non-return disc restricts clockwise or anticlockwise rotation of the knob device, and the knob device drives the wheel to rotate to tighten a shoelace; and when the knob device is pulled up, the wheel and the non-return disc are unlocked from the knob device, the wheel releases the shoelace, and simultaneously, the stop device restricts disengagement of the knob device.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a shoelace retracting device. Background technique [0002] The uses of ropes are countless: from securing materials in construction to making lamp wicks and abseiling down cliffs or setting traps for hunting. More than half of the ropes produced in the world are used in navigation and fishing. Other ropes are also used in a wide range of applications, from ordinary household clotheslines and shoelaces to heavy-duty cables for large-scale drilling operations, and they can be seen everywhere around us. [0003] The rope is strengthened by twisting or braiding, and connected into a certain length of fiber. It has good tensile strength but no compressive strength, and can be used as a tool for connection and traction. And present backpack or the opening of shoe usually all can use rope to carry out closed connection. When the existing ropes are connected and fixed, the user need...

AI Technical Summary

Problems solved by technology

When the existing ropes are connected and fixed, the user needs to use both hands to tighten the multiple ropes and then tie them into knots, which causes inconvenience to the user

In particular, people will repeat the action of knotting and unknotting the shoelaces every time they put on and take off their shoes, which is a waste of time

[0004] In particular, the internal space of the existing winding device is small, and usually requires a special smaller shoelace, which increases the cost and limits the scope of use.
