[0054] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a wire-retracting device 100, which is mainly used in daily necessities such as shoes, hats, wrist supports, and safety helmets that need to be retracted and released. The wire-retracting device 100 includes a first housing 110, a wire winding member 120 for winding a wire, a one-way member 130, a second housing 140, a first seat 150, a fastener 160, and a second seat 170.

[0055] See also Figure 4 , Figure 7 and Figure 8 The first housing 110 has a mounting cavity 111 with two ends open, and a first one-way portion 112 is disposed at one end of the first housing 110. The winding member 120 is rotatably disposed in the mounting cavity 111, and a first clamping portion 121 is disposed at one end of the winding member 120 close to the first one-way portion 112.

[0056] Combination Figure 5 and Figure 6The one-way member 130 is disposed in the installation cavity 111 and is located at one end of the winding member 120 close to the first one-way portion 112. The one-way member 130 is provided with an elastic arm 131. The circumferential edge of the elastic arm 131 is provided with a second one-way portion 1311 that matches the first one-way portion 112. The one-way member 130 is provided with a second clamping portion 132 that matches the first clamping portion 121, and is provided with a first protrusion 133. The second housing 140 is provided with a second protrusion 141 and a third protrusion 142 on one side facing the first housing 110. The second protrusion 141 matches the first protrusion 133. The first seat 150 is connected to the first housing 110, and one end of the winding member 120 away from the first one-way portion 112 is provided on the first seat 150. The fastener 160 is sequentially inserted through the winding member 120 and the one-way member 130 and is threadedly connected to the third protrusion 142 .

[0057] When the second shell 140 is rotated clockwise, the second protrusion 141 abuts against the first protrusion 133, the third protrusion 142 abuts against the end of the one-way member 130 away from the winding member 120, and the second clamping portion 132 clamps with the first clamping portion 121; when the second shell 140 is rotated counterclockwise, the second protrusion 141 separates from the first protrusion 133, the third protrusion 142 separates from the end of the one-way member 130 away from the winding member 120, and the second clamping portion 132 separates from the first clamping portion 121.

[0058] The wire-retracting and -releasing device 100 provided in the embodiment of the present application, during use, if it is necessary to tighten the wire rope, the second housing 140 is rotated in a clockwise direction, so that the one-way member 130 is driven to rotate clockwise synchronously under the abutment of the second protrusion 141 and the first protrusion 133; at the same time, in this process, the fastener 160 has a preset rotation damping, so that the second housing 140 first rotates clockwise relative to the fastener 160 to move toward the direction close to the winding member 120, thereby driving the one-way member 130 to rotate clockwise under the abutment of the third protrusion 142 and the end of the one-way member 130 away from the winding member 120. The one-way part 130 synchronously moves toward the direction close to the winding part 120, so that the second clamping part 132 is clamped with the first clamping part 121, and then under the clamping action of the second clamping part 132 and the first clamping part 121, the winding part 120, the fastener 160, the one-way part 130 and the second shell 140 are synchronously rotated clockwise as a whole, thereby realizing the tightening function of the rope; and in this process, the second one-way part 1311 and the first one-way part 112 are always kept in contact, so as to avoid the winding part 120, the fastener 160, the one-way part 130 and the second shell 140 from rotating counterclockwise as a whole synchronously, causing the rope to loosen.

[0059] When it is necessary to loosen the rope, the second shell 140 is rotated counterclockwise so that the second protrusion 141 and the first protrusion 133 change from abutment to separation; at the same time, in this process, the fastener 160 has a preset rotational damping, so that the second shell 140 rotates counterclockwise relative to the fastener 160 to move in a direction away from the winding member 120, so that the third protrusion 142 and the end of the one-way member 130 away from the winding member 120 change from abutment to separation, so that the second clamping portion 132 and the first clamping portion 121 change from clamping to separation, and then the winding member 120 can rotate freely in the counterclockwise direction to realize the function of loosening the rope, that is, the rope can be tightened or loosened by rotating the second shell 140, which is simple and convenient to operate, avoiding the technical problem of difficulty in operation caused by pulling up the second shell in the prior art.

[0060] like Figure 2 , Fig. 9 and Fig.10 As shown, in one embodiment of the present application, the first seat body 150 is provided with an avoidance hole 151 adapted to the fastener 160 , the hole wall of the avoidance hole 151 is provided with a first damping portion 1511 , and the fastener 160 is provided with a second damping portion 161 matched with the first damping portion 1511 .

[0066] like Figure 3 and Figure 5 As shown, in one embodiment of the present application, a fourth protrusion 143 is provided on a side of the second housing 140 facing the first housing 110. When the second housing 140 is rotated clockwise, the fourth protrusion 143 abuts against an end of the one-way member 130 away from the winding member 120; when the second housing 140 is rotated counterclockwise, the fourth protrusion 143 separates from an end of the one-way member 130 away from the winding member 120.

[0067] In this embodiment, the fourth protrusion 143 is provided on the side of the second housing 140 facing the first housing 110, so that in the process of tightening the wire rope, the third protrusion 142 and the fourth protrusion 143 and the one-way member 130 away from the winding member 120 are in common contact with each other, and the one-way member 130 is driven to move smoothly toward the direction close to the winding member 120. At the same time, the third protrusion 142 and the fourth protrusion 143 are in common contact with each other, and the clamping stability of the second clamping portion 132 and the first clamping portion 121 is effectively improved, thereby improving the stability of the overall synchronous clockwise rotation of the winding member 120, the fastener 160, the one-way member 130 and the second housing 140.
