It is noted that the check portion 1221 can be a pawl, and the linkage portion 141 can be an oblique tooth groove 16121 that is capable of engaging with the pawl. The housing 110 can be secured to the tongue of the shoe by rivets and can also be attached to a bag or clothing. The first clamping member 142 is of a protruding structure and the second clamping member 151 is of a slot structure. When the first clamping member 142 is engaged with the second clamping member 151, the knob 140 rotates to drive the connecting member 150 and the reel 130 to synchronously rotate, and the knob 140 can be rotated in one of a counterclockwise or a clockwise direction, but cannot be bi-directionally rotated in a clockwise or a counterclockwise direction.
The limiting component 160 comprises a guide member 161 and an elastic member, a stepped hole 152 is provided at the inner periphery of the connecting member 150, and the end of the guide member 161 close to the housing 110 is provided with a cooperation portion 1611 that matches the toggle portion 131. Multiple guide grooves 1521 are circumferentially defined and formed along the inner wall of the hole with the largest aperture of the stepped hole 152, wherein a guide clamping structure 1522 is formed between two adjacent guide grooves 1521 respectively. The elastic member abuts between the fixing member 120 and the knob 140, and the guide member 161 is movably disposed through the stepped hole 152. A clamping slider 1612 is provided along the circumferential direction of the guide member 161, wherein the clamping slider 1612 is capable of sliding inside the guide grooves 1521 and is capable of snapping with the guide clamping structure 1522.
The fastener 170 passes through the guide member 161 to connect to the knob 140, such that guide member 161 is axially fixed to knob 140 and can be rotated circumferentially.
When the knob 140 is pressed, the clamping slider 1612 slides out of the guide groove 1521 and the cooperation portion 1611 abuts against the toggle portion 131 to rotate the guide member 161 within the stepped hole 152 under the action of the toggle portion 131, such that the clamping slider 1612 is snapped with the guide clamping structure 1522 and the first clamping member 142 is snapped with the second clamping member 151, at which point the elastic member is compressed. The knob 140 is pressed again to rotate the guide member 161 within the stepped hole 152 under the action of the toggle portion 131. By utilizing the resetting elastic force generated by the compression of the elastic member to cause the clamping slider 1612 to slide from the clamping structure into the guide groove 1521, wherein the first clamping 142 is separated from the second clamping 151, at which time the elastic member recovers its elastic deformation to an initial position. The initial position is the elastic state of the elastic member before the knob 140 is pressed for the first time.
The embodiment of the present disclosure provides a winding device 100, in the course of use, for example, when tightening a cord, it only needs to press the knob 140 once to squeeze and drive the guide member 161 to move synchronously to make the clamping slider 1612 slide out of the guide groove 1521, and to make the cooperation portion 1611 to be engaged with the toggle portion 131 to rotate the guide member 161 inside the stepped hole 152 by the action of the toggle portion 131, so as to make the clamping slider 1612 to snap with the guide clamping structure 1522. The first clamping member 142 is snapped with the second clamping member 151, at which time, the elastic member is compressed, such that the linkage portion 141 is snapped with the check portion 1221 to enable the knob 140 to be rotated only in one of a clockwise direction or a counterclockwise direction, such as enabling the knob 140 to be rotated only in a clockwise direction, in this way, the knob 140 can drive the reel 130 to rotate to realize tightening of the cord.
When the cord needs to be released, on the basis of the first pressing of the knob 140, the knob 140 is pressed again, the cooperation portion 1611 abuts against the toggle portion 131 in order to rotate the guide member 161 in the stepped hole 152 under the action of the toggle portion 131, and at the same time, by utilizing the reset elasticity generated by the elastic member being compressed, the clamping slider 1612 slides from the clamping structure to the guide groove 1521, and the first clamping member 142 is separated from the second clamping member 151, at which time the elastic member will be reset, and the linkage portion 141 abuts against the check portion 1221. Certainly, in other embodiments, the linkage portion 141 and the check portion 1221 can also be separated from each other. The reel 130 can be freely rotated in the clockwise or counterclockwise direction, and the cord can be released from the reel 130. The loosening and tightening of the cord can be realized by sequentially cyclically operating the knob 140, that is, the rotation and tightening of the cord can be realized by pressing the knob 140. The operation is simple and convenient, and the technical problem of difficult operation caused by pulling up the knob in the prior art is avoided.
