In the present embodiment, the rotary cap 1 is rotatably coupled to the stationary member 2. Meanwhile, the spin cover 1 is also slidably connected to the stationary member 2 in a direction along the central axis of the spin cover 1.

As shown in fig. 4 and 7, the side wall of the rotary cover 1 is provided with a buckle 16, and the top of the fixed part 2 is provided with a circular ring-shaped retaining shoulder 17. Wherein, the stop shoulder 17 is used for limiting the moving range of the buckle 16 in the axial direction so as to avoid the separation of the rotating cover 1 and the fixed part 2.

Referring to fig. 3, the range of movement of the rotary cap 1 relative to the stationary member 2 in the axial direction is limited due to the catch 16 and the shoulder 17, thereby preventing the rotary cap 1 from being separated from the stationary member 2 when the rotary cap 1 is moved upward. In fig. 3, the shoulder 17 is in contact with the bottom surface of the inside of the spin cover 1, so that the spin cover 1 cannot move downward with respect to the stationary member 2.

The snap 16 is provided in plurality and distributed in an annular array about the central axis of the rotary cap 1. Wherein the buckle 16 may have a certain elasticity.

Referring to fig. 3 and 9, the assembly process of the rotating cover 1, the fixing member 2 and the rope winding member 3 is substantially as follows:

firstly, installing a rope rolling piece 3 in a fixing piece 2;

the rotating cover 1 is buckled on the fixing piece 2 in advance, and the jack 5 is aligned with the inserting buckle 4 and the first gear ring 10 is aligned with the second gear ring 11;

pressing the rotary cap 1 causes the catch 16 to move below the catch 17;

the rotating cover 1 is continuously pressed until the rotating cover 1 cannot move, at this time, the inserting buckle 4 is inserted into the inserting hole 5, the first gear ring 10 is sleeved with the second gear ring 11, and the pawl 6 is combined with the inner ratchet ring 7, namely, the pawl 6 is meshed with the inner ratchet ring 7.

Under the matching of the pawl 6 and the inner ratchet ring 7, the rotating cover 1 and the rope rolling piece 3 can only rotate in one direction relative to the fixed piece 2, and the rope belt is tightened; when the rope belt needs to be loosened, the rotating cover 1 can be moved axially, so that the pawl 6 is separated from the inner ratchet ring 7, at the moment, the rotating cover 1 can be rotated reversely, the rope winding piece 3 is driven to rotate synchronously, and the rope belt is loosened.

It should be noted that, in the above process, the first ring gear 10 and the second ring gear 11 are always nested and kept synchronously switched.

Referring to fig. 3, in the present embodiment, the insert buckle 4 may include two pins having elasticity. In a natural state, the two pins are in an open state and a certain distance exists between the two pins; when radially compressed, the distance between the two will decrease.

When the pawl 6 is combined with the inner ratchet ring 7, the inserting buckle 4 is inserted into the inserting hole 5, the pin is attached to the inner wall of the inserting hole 5 under the action of the elastic force of the pin, and at the moment, the pin acts on the inner wall of the inserting hole 5, so that the rotating cover 1 is subjected to component force pointing to the base 13, and the component force is parallel to the central axis of the inserting hole 5. Since the insertion hole 5 and the pawl 6 are both disposed on the rotary cover 1 and the inner ratchet ring 7 is disposed on the fixing member 2, the engagement between the pawl 6 and the inner ratchet ring 7 is more stable, thereby preventing the separation of the pawl 6 from the inner ratchet ring 7 due to vibration or shaking. In fig. 3, the pawl 6 is engaged with the inner ratchet ring 7.

Under the condition that the rotating cover 1 is not pulled by external force, the pawl 6 and the inner ratchet ring 7 can be always kept in a combined state through the interaction between the insertion hole 5 and the insertion buckle 4.

When the rotary cover 1 is pulled by external force and moves upwards, the inner wall of the plug hole 5 presses the pins, the distance between the two pins is reduced, and meanwhile, the plug buckle 4 and the plug hole 5 slide relatively in the axial direction. In the axial direction, the rotary cap 1 is displaced relative to the stationary part 2, which finally causes the detent 6 to disengage from the inner detent ring 7.

As shown in fig. 6 and 7, in order to facilitate the installation of the rope belt, the middle shell 12 may be provided with a rope threading hole 18, and the rope rolling member 3 may be provided with a rope inlet hole 19 corresponding to the rope threading hole 18. Wherein, a plurality of rope threading holes 18 are arranged, and the rope inlet hole 19 is arranged in the rope groove 20 of the rope rolling piece 3.

The end part of the rope belt is sequentially penetrated into the rope rolling piece 3 through the rope penetrating hole 18 and the rope inlet hole 19; the end of the rope is extended out of the opening at the bottom of the rope rolling piece 3, then the end of the rope is knotted to be thickened and not slide out of the rope inlet hole 19, and then the rope rolling piece 3 is installed on the fixing piece 2. When winding, the rope winding member 3 rotates relative to the middle shell 12, and the rope is wound on the rope groove 20 on the outer side wall of the winding member, so that the rope is tightened.

In this embodiment, an article with a string adjusting device is also provided, which includes the string adjusting device.

The rope belt adjusting device can be applied to articles such as shoes, clothes, backpacks or medical protectors.
