[0057] like Figures 1 to 3 , Figure 19 As shown, an embodiment of this application provides a rope winding and unwinding device 100, which is mainly used in daily necessities such as shoes, bags and clothes that have ropes that need to be wound and unwound.

The reel assembly 140 passes through the first limiting hole 1102, and a part of the reel assembly 140 is located in the receiving cavity 1101.

[0059] The check disc 120 is arranged on the base 110 and located on the side away from the accommodating cavity 1101. A plurality of buckles can be arranged along the circumference of the first limiting hole 1102 of the base 110, and the check disc 120 is fixed on the base 110 through the buckles. Of course, the check disc 120 can also be fixed on the base 110 in a threaded connection mode or an adhesive mode through the through hole 1414. At the same time, the check disc 120 has a main check piece 121. The side of the rotating cover 130 facing the base 110 is provided with an engaging piece 131 and a slave check piece 132 engaged with the main check piece 121.

[0060] In combination Figure 4 and Figure 5 As shown in the figure, the wire wheel assembly 140 includes a wire winding wheel 141, a guide knob 142, a clamping piece 143 and an elastic piece 144. The wire winding wheel 141 is movably arranged in the accommodating cavity 1101. The clamping piece 143 is arranged on the side of the wire winding wheel 141 facing the rotating cover 130, and the clamping piece 143 is arranged through the first limiting hole 1102 and can be clamped with the engaging piece 131.

[0061] In combination Figure 9 and Figure 10 As shown in the figure, at the same time, the clamping piece 143 is provided with a second limiting hole 14311, and the first clamping structure 1432 and the second clamping structure 1433 are arranged on the inner wall of the second limiting hole 14311 in a staggered manner.

[0062] In combination Figure 13 As shown in the figure, the guide knob 142 is movably arranged through the second limiting hole 14311 and connected with the rotating cover 130. The guide knob 142 is provided with a third clamping structure 1421, and the third clamping structure 1421 can be clamped with the first clamping structure 1432 or the second clamping structure 1433, respectively. The elastic piece 144 is supported between the wire winding wheel 141 and the guide knob 142.

[0063] The rope winding and unwinding device 100 provided by the embodiment of the present application can fix the two ends of the rope 160 on the wire winding wheel 141 respectively during use. When it is needed to tighten the rope 160, the rotating cover 130 is pressed, and the guide knob 142 rotates in the clockwise direction or the counterclockwise direction in the second limiting hole 14311 (refer to the arrow direction in the figure). At the same time, the third clamping structure 1421 of the guide knob 142 is clamped with the first clamping structure 1432 or the second clamping structure 1433, so that the wire winding wheel 141 rotates in the clockwise direction or the counterclockwise direction. Figure 2When the rotating cover 130 is pressed for the first time, the guide knob 142 rotates in the second limiting hole 14311, the third clamping structure 1421 is separated from the second clamping structure 1433 and clamped with the first clamping structure 1432, the main check piece 121 is clamped with the slave check piece 132, the clamping piece 131 is clamped with the clamping piece 143, and the elastic piece 144 is in a compressed state. At this time, the winding wheel 141 cannot be reversed and can only rotate in one of the clockwise direction S and the counterclockwise direction N, i.e., only rotates in the clockwise direction S, that is, the rotating cover 130 can only rotate in the clockwise direction S, so that the rotating cover 130 can drive the winding wheel 141 to rotate to tighten the rope 160.

[0064] When the rotating cover 130 is pressed for the first time, the guide knob 142 rotates in the second limiting hole 14311, the third clamping structure 1421 is separated from the second clamping structure 1433 and clamped with the first clamping structure 1432, the main check piece 121 is clamped with the slave check piece 132, the clamping piece 131 is clamped with the clamping piece 143, and the elastic piece 144 is in a compressed state. At this time, the winding wheel 141 cannot be reversed and can only rotate in one of the clockwise direction S and the counterclockwise direction N, i.e., only rotates in the clockwise direction S, that is, the rotating cover 130 can only rotate in the clockwise direction S, so that the rotating cover 130 can drive the winding wheel 141 to rotate to tighten the rope 160.

[0065] In this embodiment, the elastic piece 144 is supported between the winding wheel 141 and the guide knob 142, and the guide knob 142 is connected with the rotating cover 130. In this way, when the rotating cover 130 is pressed back and forth, the guide knob 142 easily lifts the rotating cover 130, avoiding the phenomenon that the reset spring in the prior art is supported between the rotating cover 130 and the limiting piece, causing the rotating cover 130 to be jammed, and the rope 160 is not easy to be wound and unwound, improving the user experience.

[0066] As shown in Figure 3 and Figure 18 In one embodiment, the clamping piece 131 includes a groove body 1311 and a plurality of first inclined teeth 1312, the plurality of first inclined teeth 1312 are arranged on the inner groove wall of the groove body 1311 in a circumferential direction, and the tooth root of the first inclined tooth 1312 is located at the groove bottom of the groove body 1311.

[0067] As shown in Figures 9 to 11 The clamping piece 143 includes a body 1431 and a plurality of second inclined teeth 1434, the body 1431 is provided with the second limiting hole 14311, the plurality of second inclined teeth 1434 are arranged on the outer wall of the body 1431 in a circumferential direction, the tooth root of the second inclined tooth 1434 is located on one side of the winding wheel 141, and the plurality of second inclined teeth 1434 are clamped with the plurality of first inclined teeth 1312.

[0068] In the embodiment, the engaging member 131 and the engaging member 143 are engaged by the first inclined teeth 1312 and the second inclined teeth 1434 during the pressing of the rotating cover 130, and the tip portions of the first inclined teeth 1312 and the second inclined teeth 1434 are oppositely arranged, so that the engagement between the first inclined teeth 1312 and the second inclined teeth 1434 is guided, facilitating the engagement between the first inclined teeth 1312 and the second inclined teeth 1434.

[0069] As shown in Figs. 1 and 2, the rotating cover 130 is provided with a plurality of first inclined teeth 1312, and the first inclined teeth 1312 are arranged on the inner wall of the rotating cover 130. Figure 7 As shown in Figs. 1 and 2, the rotating cover 130 is provided with a plurality of first inclined teeth 1312, and the first inclined teeth 1312 are arranged on the inner wall of the rotating cover 130. Figure 8 As shown in Figs. 1 and 2, the rotating cover 130 is provided with a plurality of first inclined teeth 1312, and the first inclined teeth 1312 are arranged on the inner wall of the rotating cover 130.

[0070] Further, the inner wall of the recess 1411 is provided with a first engaging portion 1413 on each of the opposite sides, and the outer wall of the body 1431 is provided with a second engaging portion 14312 which is engaged with the first engaging portion 1413. Thus, when the body 1431 is installed on the winding wheel 141, the body 1431 is limited in the circumferential direction by the engagement between the second inclined teeth 1434 and the first engaging slot 1412, and the body 1431 is limited in the axial direction of the winding wheel 141 by the engagement between the first engaging portion 1413 and the second engaging portion 14312, so that the body 1431 is installed on the winding wheel 141, and the structure is simple and facilitates assembly and manufacturing.

[0071] It should be noted that the first engaging portion 1413 and the second engaging portion 14312 can be respectively a hook 134, and of course, in other embodiments, the first engaging portion 1413 can be a clamping hole, and the second engaging portion 14312 can be a hook 134.

[0072] In the above embodiment in which the winding wheel 141 has the recess 1411, the bottom of the recess 1411 is provided with a through hole 1414. The through hole 1414 is provided in the bottom of the recess 1411, and a through hole is also provided in the guiding knob 142, so that the rotating cover 130 is connected to the guiding knob 142 by screws passing through the through hole 1414, the through hole and the rotating cover 130 in sequence during assembly.

[0074] In combination Figure 13 and Figure 14 As shown, one side of the guide knob 142 facing the first toothed surface 14151 is defined with a second toothed surface 1422 matching the first toothed surface 14151, and the first toothed surface 14151 and the second toothed surface 1422 can abut and slide.

[0075] It can be understood that when the rotating cover 130 is pressed, the guide knob 142 rotates in the second limiting hole 14311, and the second toothed surface 1422 cooperates with the first toothed surface 14151, so that during the rotation of the guide knob 142, the first toothed surface 14151 cooperates with the second toothed surface 1422 to form an up-and-down type rotation.

[0076] As shown in Figure 3 , Figure 5 and Figure 6 In any one of the above embodiments, optionally, the elastic member 144 is a cylindrical spring, one end of the cylindrical spring abuts in the mounting groove surrounded by the annular protrusion 1415, and the other end abuts on the guide knob 142. At the same time, the inner diameter of the mounting groove can be equal to the outer diameter of the cylindrical spring, so that the assembly of the cylindrical spring and the mounting groove is more compact and stable, facilitating the installation and positioning of the elastic member 144.

[0077] As shown in Figure 10 and Figure 11 In any one of the above embodiments, the first clamping structure 1432 includes a first stepped surface 14321 and a second stepped surface 14322, and the first stepped surface 14321 and the second stepped surface 14322 are respectively first inclined surfaces. The second clamping structure 1433 is a clamping groove, the third clamping structure 1421 is a clamping block, and one end surface of the clamping block away from the winding wheel 141 is a second inclined surface 14211, and the first inclined surface and the second inclined surface 14211 have the same inclined direction.

[0078] In the embodiment, when the rotating cover 130 is pressed, the second inclined surface 14211 of the clamping block abuts against the first step surface 14321, and during the rotation of the guide knob 142, the second inclined surface 14211 of the clamping block moves from the first step surface 14321 to the second step surface 14322, and then clamps into the clamping groove, so as to realize the clamping of the second clamping structure 1433 and the third clamping structure 1421. When the rotating cover 130 is pressed again, the clamping block slides out of the clamping groove and clamps on the first step surface 14321.

[0079] As shown in Figure 3 and Figure 19 In any one of the above embodiments, the rope winding and unwinding device 100 optionally further comprises a positioning member 150, and the positioning member 150 is connected with the guide knob 142 and the rotating cover 130 respectively. The guide knob 142 and the rotating cover 130 are connected through the positioning member 150.

[0080] In the embodiment, the positioning member 150 is a screw, which is connected with the guide knob 142 and the rotating cover 130 in sequence.
