Rotary rope object winding and unwinding device, shoe and object

Abstract

The invention provides a rotary rope object winding and unwinding device. A rotary knob conducts rotation driving and rope object loosening operation on a winding shaft through a winding and unwinding adjusting structure, wherein the rotation driving is used for tightening a rope object; the bottom column and the knob column are sleeved inside and outside and mutually limited in the radial direction for coaxial rotation, so that the coaxiality, stability and smoothness of the rotation of the winding shaft and the stability and smoothness of the rotation of the knob are ensured. The winding shaft is contained through the rotary knob instead of being contained through a traditional base body structure, the opening of the rotary knob is blocked through the bottom cover, the winding shaft can sink into the rotary knob through the structure, the rope winding height is increased, the rope inlet height is relatively reduced, and operation is conducted by fully utilizing the overall height of the winding and unwinding device; and the button side wall is in close running fit contact with the bottom cover, dust, sandy soil and other tiny impurities are prevented from entering the interior, and lasting, stable and normal work of all components is ensured. The device has the advantages of stable working performance, smooth, efficient and convenient operation, dust prevention, sand prevention and the like. The invention also provides a shoe and an article.

Description

Technical field [0001] The invention involves the field of daily life, and it is specific to a rotary rope collection device, shoes and items. Background technique [0002] Shoes and clothes, backpacks, hats, protective gear and other items are usually set to tighten or relax at the opening of the opening of items such as rope bands. At present, people are fixed to the tightness of the rope by knotting. Cumbersome operation, easy to relax and not concise enough. [0003] In order to solve the problem in the previous problem, China's utility model CN201820751299.8 discloses a rotor -based straps system, including rotor and stator. Its characteristics are The rotor and the expansion bracket are connected in turn, which is opened in the direction of the rotor in the direction of the circle. Corresponding to the settings, the stator setting has a gear structure, which is a bite or separation connection through the gear structure through the gear structure. The main subject and extens...

Problems solved by technology

[0004] The utility model solves the problem of manually tying shoelaces to a certain extent through the way of retracting and releasing the rope through the knob, but its structure is complicated, the processing and assembly procedures are cumbersome, the cost is high, the strength is insufficient, the process is complicated, and the work stability and operation The smoothness is still insufficient, and most of its accessories require complex molds for demoulding, which is costly and inefficient, especially when there is a gap between the knob and the side wall of the seat, and small debris such as dust and sand can easily enter the interior and affect the work of internal components Stability and service life, if it may get stuck or block the fittings of each tooth and the action gap, etc., resulting in malfunction or even damage
