[0055] As shown in Figures 1, 4, 7 and 8, an embodiment of the present application provides a wire reel 100, which is mainly used in daily necessities such as shoes, bags and clothes that need to be retracted with wire ropes. The wire reel 100 may include a base 110, a fixing part 120, a winding wheel 130 for winding the wire, a knob 140, a connecting part 150, a limiting assembly 160 and a fastener 170.

[0056] Referring to Figures 2, 3, 5, and 6, the fixing member 120 can be connected to the base 110 by a snap-fit ​​connection. The fixing member 120 can be provided with a through cavity 121 with both ends open. An elastic arm 122 can be provided at the end of the fixing member 120 away from the base 110, and a non-return portion 1221 can be provided on the circumferential edge of the elastic arm 122. The winding reel 130 is axially rotatably disposed within the through cavity 121. A toggle portion 131 can be provided at the end of the winding reel 130 away from the base 110. A linkage portion 141 and a first snap-fit ​​member 142 can be provided on the side of the knob 140 facing the fixing member 120. The linkage portion 141 can cooperate with the non-return portion 1221. The connecting member 150 can be connected to the end of the winding wheel 130 away from the base 110. The connection method can be snap-fitting so that the winding wheel 130 and the connecting member 150 can rotate synchronously. The outer circumference of the connecting member 150 can be provided with a second snap-fitting member 151 that cooperates with the first snap-fitting member 142.

[0057] It should be noted that the non-return portion 1221 may be a pawl, and the linkage portion 141 may be an oblique tooth 16121 that can engage with the pawl. The base 110 can be fixed to the tongue of a shoe by rivets, or it can be fixed to a bag or clothing. The first clamping member 142 may be a protruding structure, and the second clamping member 151 may be a slot structure. When the first clamping member 142 is engaged with the second clamping member 151, the rotation of the knob 140 can drive the connecting member 150 and the winding wheel 130 to rotate synchronously. The knob 140 can rotate in one direction, either counterclockwise or clockwise, but cannot rotate in both directions, clockwise or counterclockwise.

[0058] The limiting assembly 160 may include a guide member 161 and an elastic member. A stepped hole 152 may be provided on the inner circumference of the connecting member 150. A matching portion 1611 that cooperates with the toggle portion 131 may be provided on the end of the guide member 161 close to the base 110. A plurality of guide grooves 1521 are defined along the circumference of the inner wall of the hole with the largest aperture of the stepped hole 152. A guide clamping structure 1522 is formed between two adjacent guide grooves 1521. The elastic member may abut between the fixing member 120 and the knob 140. The guide member 161 may be movably inserted into the stepped hole 152. A clamping slider 1612 may be provided along the circumference of the guide member 161. The clamping slider 1612 can slide in the guide groove 1521 and can be clamped with the guide clamping structure 1522.

[0059] The fastener 170 is passed through the guide member 161 and connected to the knob 140 , so that the guide member 161 and the knob 140 are axially fixed and circumferentially rotatable.

[0060] When the knob 140 is pressed, the locking slider 1612 can slide out of the guide groove 1521, and the matching portion 1611 can abut against the toggle portion 131, so that the guide member 161 can rotate in the stepped hole 152 under the action of the toggle portion 131, so that the locking slider 1612 is locked with the guide locking structure 1522, and the first locking member 142 can be locked with the second locking member 151, and the elastic member is compressed at this time. Press the knob 140 again to make the guide member 161 rotate in the stepped hole 152 under the action of the toggle portion 131, and utilize the restoring elastic force generated by the compression of the elastic member to make the clamping slider 1612 slide from the clamping structure to the guide groove 1521, and the first clamping member 142 can be separated from the second clamping member 151. At this time, the elastic member restores its elastic deformation to the initial position, which is the elastic state of the elastic member before the knob 140 is pressed for the first time.

[0061] The wire take-up device 100 provided in the embodiment of the present application, during use, such as when tightening the wire rope, only needs to press the knob 140 once to squeeze and drive the guide member 161 to move synchronously so that the clamping slider 1612 slides out of the guide groove 1521, and the matching portion 1611 abuts against the toggle portion 131, so that the guide member 161 rotates in the stepped hole 152 under the action of the toggle portion 131, thereby clamping the clamping slider 1612 with the guide clamping structure 1522, and the first clamping member 142 is clamped with the second clamping member 151. At this time, the elastic member can be compressed, and the linkage portion 141 can be clamped with the check portion 1221, so that the knob 140 can only rotate in one direction of the clockwise direction or the counterclockwise direction, such as making the knob 140 only rotate in the clockwise direction. In this way, the knob 140 can drive the winding wheel 130 to rotate to tighten the wire rope.

[0062] If the line needs to be loosened, the knob 140 is pressed again after the first press, and the matching portion 1611 can abut against the toggle portion 131, so that the guide member 161 can rotate in the stepped hole 152 under the action of the toggle portion 131. At the same time, the elastic member is compressed to generate a restoring force so that the engaging slider 1612 can slide from the engaging structure to the guide groove 1521, and the first engaging member 142 can be separated from the second engaging member 151. At this time, the elastic member is reset, and the linkage portion 141 can be engaged with the non-return portion 1221. Of course, in other embodiments, the linkage portion 141 and the non-return portion 1221 can also be separated. The winding wheel 130 can rotate freely in the clockwise or counterclockwise direction, and the rope can be loosened from the winding wheel 130. The tightness of the rope can be achieved by pressing the knob 140 in a circular operation. That is, the rotation tightness of the rope can be achieved by pressing the knob 140. The operation is simple and convenient, and avoids the technical problem of difficulty in operation caused by pulling up the knob in the related art.

[0063] As shown in Figures 3, 6, 12 and 13, in one embodiment of the present application, optionally, a plurality of bevel teeth 16121 are arranged at intervals along the circumference of the guide member 161, and the plurality of bevel teeth 16121 form the clamping slider 1612, the toggle portion 131 has a first toothed edge 1311, and the mating portion 1611 has a second toothed edge 16111 mating with the first toothed edge 1311.

[0064] In this embodiment, during use, such as when tightening the rope, it is only necessary to press the knob 140 once to squeeze and drive the guide member 161 to move synchronously so that the bevel teeth 16121 slide out of the guide groove 1521, and the second toothed edge 16111 abuts against the first toothed edge 1311, so that under the action of the first toothed edge 1311, the guide member 161 rotates in the stepped hole 152, so that the bevel teeth 16121 can be engaged with the guide clamping structure 1522, and the first clamping member 142 can be engaged with the second clamping member 151. At this time, the elastic member is compressed, and the linkage portion 141 can be engaged with the check portion 1221. In this way, the knob 140 can drive the winding wheel 130 to rotate to tighten the rope.

[0065] If the line needs to be loosened, after pressing the knob 140 for the first time, press the knob 140 again, and the second toothed edge 16111 can abut against the first toothed edge 1311, so that the guide member 161 can rotate in the stepped hole 152 under the action of the first toothed edge 1311, and at the same time, the reset elastic force generated by the compression of the elastic member can be used to make the bevel teeth 16121 slide from the clamping structure to the guide groove 1521, and the first clamping member 142 can be separated from the second clamping member 151. At this time, the elastic member is reset, and the linkage portion 141 is clamped with the check portion 1221. Of course, in other embodiments, the linkage portion 141 can also be separated from the check portion 1221, and the winding wheel 130 can rotate freely in the clockwise or counterclockwise direction, and the line can be loosened from the winding wheel 130.

[0066] As shown in Figures 3, 6, 11 and 12, in the above-mentioned embodiment of the present application, optionally, the guide clamping structure 1522 is a step-like structure 15221, and the step-like structure 15221 includes a first step surface 152211 and a second step surface 152212, and the first step surface 152211 and the second step surface 152212 are respectively inclined surfaces, and have the same inclination direction as the bevel tooth 16121.

[0067] In this embodiment, when the knob 140 is pressed, the knob 140 can push the bevel tooth 16121 to move downward along the guide groove 1521 to the junction of the guide groove 1521 and the second step surface 152212. At this time, the elastic member can be compressed to generate elastic force. After releasing the knob 140, the bevel tooth 16121 can move from the junction of the guide groove 1521 and the second step surface 152212 to the position of the second step surface 152212 close to the first step surface 152211 under the action of the elastic force of the elastic member and the first toothed edge 1311, and be clamped at the position of the second step surface 152212 close to the first step surface 152211, and the elastic member is still in a compressed state.

[0068] When the knob 140 is pressed again, the knob 140 can push the bevel tooth 16121 to move downward along the interface between the second step surface 152212 and the first step surface 152211 to the junction of the first step surface 152211 and the second step surface 152212. The elastic member can still be in a compressed state. After releasing the knob 140, the bevel tooth 16121 can move from the junction of the first step surface 152211 and the second step surface 152212 to the first step surface 152211 under the action of the reset elastic force of the elastic member and the first toothed edge 1311, and move along the first step surface 152211 to the guide groove 1521 to restore to its initial position.

[0069] In the above embodiment of the present application, optionally, the first toothed edge 1311 and the winding wheel 130 are integrally injection-molded.

[0070] In this embodiment, the first toothed edge 1311 and the winding wheel 130 can be made by integral injection molding. This not only improves the connection stability between the toggle portion 131 and the winding wheel 130, but also makes the structure compact, improves space utilization, and helps to reduce the overall thickness of the winder 100. At the same time, the integral injection molding can also eliminate the installation step of installing the toggle portion 131 on the winding wheel 130, thereby improving the overall installation efficiency of the winder 100.

[0071] As shown in Figure 12, in one embodiment of the present application, optionally, a first clamping portion 132 is provided at one end of the winding wheel 130 away from the base 110, and a second clamping portion 153 is provided at one end of the connecting member 150 close to the base 110 to be clamped with the first clamping portion 132.
