[0002] In order to make some daily necessities suitable for different users, many daily necessities are designed with drawstrings, such as sneakers, hats, sports shirts, gloves, etc. The tightness of the items can be adjusted by tying the drawstrings. However, in daily life, the knotted drawstrings are sometimes easy to loosen and detach, such as loose shoelaces, which can easily cause dirtiness and tripping. In particular, children who are too young cannot tie the ropes by themselves, and the elderly are physically weak, so bending over to tie the ropes is also very inconvenient and easy to cause danger. Summary of the invention

[0003] In order to solve the above technical problems, it is necessary to provide a rope and wire retracting device, shoes, gloves, medical protective gear and a storage device.

[0010] Wherein, when the first meshing portion is meshed with the second meshing portion and the knob is rotated in a first clockwise direction, the knob can drive the pawl disk to rotate, and then the pawl disk drives the wire wheel to rotate, so that the wire retracting device is in a wire retracting state and the wire can be wound around the winding portion to retract the wire;

[0011] When the knob rotates in a second direction opposite to the first clockwise direction, the driving member drives the connecting portion to disengage the first engaging portion from the second engaging portion, so that the rope retracting device is in a released state, and then the wire wheel can rotate to release the rope.

[0012] Compared with the prior art, in the rope and wire retracting device of the present application, when the first meshing portion of the ratchet disk meshes with the second meshing portion of the wire wheel and the knob rotates in a first clockwise direction, the knob can drive the ratchet disk to rotate, and then the ratchet disk drives the wire wheel to rotate, so that the rope and wire retracting device is in a wire-reeling state and the wire can be wound around the winding portion of the wire wheel to reel in the wire; when the knob rotates in a second direction opposite to the first clockwise direction, the driving member of the knob drives the connecting portion of the ratchet disk so that the first meshing portion of the ratchet disk disengages from the second meshing portion of the wire wheel, so that the rope and wire retracting device is in a released state, and then the wire wheel can rotate in the base to release the wire.

Moreover, the small number of components can also improve the stability of the overall structure and improve the reliability and service life of the rope and wire retracting device.

[0013] In one embodiment, the knob further includes a top block disposed on one side of the cover plate, and the top block is used to abut between the inner side of the first check member and the winding portion in the release state to prevent the first check member from being separated from the second check member. It can be understood that the top block can prevent the first check member from being separated from the second check member in the release state, facilitate switching from the release state to the winding state, and improve the reliability of the rope and line winding device.

[0014] In one embodiment, the positioning block includes an inner side surface and an outer side surface, and the distance between the inner side surface and the outer side surface gradually decreases along the first clockwise direction. The positioning block can be used to gradually increase the abutting force, thereby achieving the effect of effectively abutting and preventing the first check piece from separating from the second check piece.

[0015] In one embodiment, the connecting portion comprises a cylinder, and the side surface of the driving member is used to abut against the outer circumference of the cylinder to drive the connecting portion. It can be understood that by making the connecting portion a cylinder and the side surface of the driving member abut against the outer circumference of the cylinder, it can be ensured that the driving member drives the connecting portion smoothly, so that the rope retracting and releasing device smoothly completes the switching from the retracting state to the releasing state.

[0016] In one embodiment, the connecting part also includes an extension block connected to the cylinder, and the extension block is used to abut the top block in the release state; the driving member includes a driving body and a stopping portion connected to the driving body, and the side surface of the driving body is used to abut the outer peripheral surface of the top block to drive the connecting part; the stopping portion is bent and connected to the driving body, and is used to stop the top block after driving the connecting part, so as to prevent the first engaging portion from sliding out to the outside of the driving member, thereby causing the release state to fail to be achieved.

[0017] In one embodiment, the first engaging portion includes an anti-positive rotation engaging portion and an anti-reverse engaging portion. When the rope and line retracting device is in the retracting state, the anti-reverse engaging portion engages with the second engaging portion; when the rope and line retracting device is in the releasing state, the anti-positive rotation engaging portion engages with the second engaging portion. The anti-positive rotation engaging portion and the anti-reverse engaging portion can effectively prevent the rotation phenomenon caused by accidental touch or automatic rebound, thereby improving the reliability of the rope and line retracting device.

[0018] In one embodiment, the number of the second engaging parts is at least two and they are distributed in sequence along the circumferential direction, the number of the anti-forward rotation engaging parts and the anti-reverse rotation engaging parts are both at least two and they are distributed in sequence along the circumferential direction; the number of the first meshing part and the connecting part are both at least two and they are distributed in sequence along the circumferential direction; the number of the first check members and the second check members is at least two and they are distributed in sequence along the circumferential direction; the number of the driving member and the top block is consistent with and corresponds to the number of the connecting parts; the first check member includes an elastic arm and a first check tooth portion connected to the elastic arm, and the second check member includes a plurality of second check teeth portions connected in sequence along the circumferential direction; the first meshing part includes a connecting arm and a first meshing tooth portion connected to the connecting arm, and the second meshing part includes a plurality of second meshing teeth portions connected in sequence along the circumferential direction. It can be understood that by providing the above-mentioned number of the second engaging portion, the anti-forward rotation engaging portion, the anti-reverse rotation engaging portion, the first meshing portion, the connecting portion, the first check piece, the second check piece, the driving member and the top block, the second check tooth portion and the second meshing tooth portion, the technical effect of improving the stability and reliability of the rope retracting and releasing device can be achieved.

[0019] In one embodiment, the knob includes a protruding structure disposed in the middle area of ​​the cover plate, the anti-positive rotation engaging portion and the anti-reverse engaging portion are grooves sequentially formed on the outer side of the protruding structure, the base plate includes a groove structure disposed in the middle area, the second engaging portion includes a hook extending into the groove structure, and the hook is used to engage with the groove of the anti-positive rotation engaging portion or the groove of the anti-reverse engaging portion. Since the hook and the groove have a simple structure and high reliability, the cooperation of the hook and the groove can stably prevent the rotation phenomenon caused by accidental touch or automatic rebound, thereby improving the reliability of the rope and line retracting device.

[0020] In one embodiment, the outer side surface of the protrusion structure is further provided with a first limiting portion, and the side wall surface of the groove structure is further provided with a second limiting portion, one of the first limiting portion and the second limiting portion is a limiting block, and the other of the first limiting portion and the second limiting portion is a limiting slide, and the limiting block is used to slide in the limiting slide to limit the relative rotation angle of the knob and the pawl disk, so that the anti-positive rotation engaging portion and the anti-reverse engaging portion of the knob are engaged or disengaged with the second engaging portion of the pawl disk in sequence. It can be understood that, since the limiting block and the limiting slide are simple in structure and highly reliable, the relative rotation angle of the knob and the pawl disk can be limited through the cooperation of the limiting block and the limiting slide, so that the anti-positive rotation engaging portion and the anti-reverse engaging portion of the knob are engaged or disengaged with the second engaging portion of the pawl disk in sequence, thereby improving the stability of the rope retracting device and the user experience.

[0021] In one embodiment, the groove includes a first surface and a second surface connected by a bend, the raised structure has an arc surface connecting the first surface and the second surface, and the angle formed by the first surface and the tangent of the connection point of the arc surface connecting the first surface is different from the angle formed by the second surface and the tangent of the connection point of the arc surface connecting the second surface, so that the external force required for the hook to disengage from the groove of the anti-positive rotation engaging portion is less than the external force required for the hook to disengage from the groove of the anti-reverse engaging portion. It can be understood that through the setting of the above structure, the external force required for the hook to disengage from the groove of the anti-positive rotation engaging portion can be less than the external force required for the hook to disengage from the groove of the anti-reverse engaging portion, thereby improving the user experience.

[0022] In one embodiment, the anti-positive rotation engaging portion and the anti-reverse engaging portion are grooves sequentially arranged on the cover plate along the circumferential direction, and the second engaging portion is a clamping block arranged on the winding portion, and the clamping block is used to engage with the groove of the anti-positive rotation engaging portion or the groove of the anti-reverse engaging portion. Since the clamping block and the groove have a simple structure and high reliability, the cooperation of the clamping block and the groove can stably prevent the rotation phenomenon caused by accidental touch or automatic rebound, thereby improving the reliability of the rope and line retracting device.

[0023] In one embodiment, a first limiting portion is further provided on one side of the cover plate, and a second limiting portion is further provided on the side of the winding portion close to the cover plate, one of the first limiting portion and the second limiting portion is a limiting block, and the other of the first limiting portion and the second limiting portion is a limiting slide groove, and the limiting block is used to slide in the limiting slide groove to limit the relative rotation angle of the knob and the pawl disk, so that the anti-forward rotation engaging portion and the anti-reverse rotation engaging portion of the knob are engaged or disengaged with the second engaging portion of the pawl disk in sequence; the number of the first limiting portion and the second limiting portion is at least two and distributed along the circumferential direction. It can be understood that since the limit block and the limit slot have a simple structure and high reliability, the relative rotation angle of the knob and the pawl disk can be limited through the cooperation of the limit block and the limit slot, so that the anti-forward rotation engaging portion and the anti-reverse rotation engaging portion of the knob are engaged or disengaged with the second engaging portion of the pawl disk in turn, thereby improving the stability of the rope retracting device and the user experience.

[0024] In one embodiment, the axial height of the blocking block along the direction from the knob to the pawl disk is smaller than the height of the limiting block along the axial height, which can ensure that when the blocking block is engaged and switched with different grooves, the knob and the pawl disk remain connected and their relative positions are restricted to prevent over-rotation of the knob.

[0025] In one embodiment, the groove includes a first surface and a second surface that are connected by a bend, and the angle between the main body surface on one side of the cover plate and the first surface is different from the angle between the main body surface on one side of the cover plate and the second surface, so that the external force required for the card block to disengage from the groove of the anti-positive rotation engaging portion is less than the external force required for the card block to disengage from the groove of the anti-reverse engaging portion. It can be understood that through the arrangement of the above structure, the external force required for the card block to disengage from the groove of the anti-positive rotation engaging portion is less than the external force required for the card block to disengage from the groove of the anti-reverse engaging portion, thereby improving the user experience.

[0070] The base 30 includes a side wall structure 31 arranged around the periphery of the pawl disk 20, a second check piece 32 formed on the inner surface of the side wall structure 31, and a second limit piece 33 formed on the side wall structure 31. The side wall structure 31 accommodates the pawl disk 20. The side wall structure 31 also has a first wire entry hole 34 extending therethrough, and the second check piece 32 engages with the first check piece 23, so that the pawl disk 20 can rotate along a predetermined clockwise direction relative to the base 30. The second limit piece 33 extends into the storage space (not marked) surrounded by the cover plate 11 and the side plate 13, and can be limited in the storage space by the first limit piece 14, and the knob 10 can drive the pawl disk 20 to rotate.

[0071] The wire wheel 40 is located in the side wall structure 31 and is arranged on the side of the pawl disk 20 away from the knob 10. It includes two substrate parts 42 arranged opposite to each other, a winding part 43 connected between the two substrate parts 42, an extension wall 41 connected to the substrate 21 close to the pawl, and a second engaging part 46 arranged on the inner side of the extension wall 41 and used to cooperate with the first engaging part 24. The winding part 43 includes a second wire entry hole 45, so that the rope can pass through the first wire entry hole 34 and the second wire entry hole 45 and be arranged on the wire wheel 40.

[0073] When the first engaging portion 24 is engaged with the second engaging portion 46 and the knob 10 is rotated in the first clockwise direction, the knob 10 can drive the pawl disk 20 to rotate, and then the pawl disk 20 drives the wire wheel 40 to rotate, so that the rope retracting device 1 can be in a reeling state and the rope can be wound around the winding portion 43 of the wire wheel 40 to reel in the rope.

[0074] When the knob 10 rotates in a second direction opposite to the first clockwise direction, the driving member 15 drives the connecting portion 25 to disengage the first engaging portion 24 from the second engaging portion 46, so that the rope retracting device 1 is in a released state, and then the wire wheel 40 can rotate to release the rope.

[0075] Compared with the prior art, in the rope and line retracting device 1 of the present application, when the first meshing portion 24 of the ratchet disk 20 meshes with the second meshing portion 46 of the reel 40 and the knob 10 rotates in a first clockwise direction, the knob 10 can drive the ratchet disk 20 to rotate, and then the ratchet disk 20 drives the reel 40 to rotate, so that the rope and line retracting device 1 is in a reeling state and the rope can be wound around the winding portion 43 of the reel 40 to reel the rope; when the knob 10 rotates in a second clockwise direction opposite to the first clockwise direction, the driving member 15 of the knob 10 drives the connecting portion 25 of the ratchet disk 20 so that the first meshing portion 24 of the ratchet disk 20 is disengaged from the second meshing portion 46 of the reel 40, so that the rope and line retracting device 1 is in a released state, and then the reel 40 can rotate to release the rope. The rope and line retracting device 1 can realize forward reeling and reverse release of the rope, and is simple to operate and has a high user experience. In addition, the rope and line retracting and releasing device 1 has a relatively small number of overall components, which can not only reduce assembly costs and improve assembly efficiency, but also make the overall structure compact, which is conducive to the miniaturization and lightweight of the rope and line retracting and releasing device 1. Moreover, the relatively small number of components can also improve the stability of the overall structure, and improve the reliability and service life of the rope and line retracting and releasing device 1. It can be understood that the forward rotation refers to rotation in the first clockwise direction, and the reverse rotation refers to rotation in the second clockwise direction opposite to the first clockwise direction, wherein, in one embodiment, the first clockwise direction can be a clockwise direction, and the second clockwise direction is a counterclockwise direction; in other embodiments, the first clockwise direction can be a counterclockwise direction, and the second clockwise direction is a clockwise direction.

It can be understood that the top block 16 can prevent the first check member 23 from being separated from the second check member 32 in the release state, thereby facilitating switching from the release state to the winding state and improving the reliability of the rope and line winding device 1.

[0077] In the first and second embodiments, the positioning block 16 includes an inner side surface 161 and an outer side surface 162, and the distance between the inner side surface 161 and the outer side surface 162 gradually decreases along the first clockwise direction. The positioning block 16 can be used to gradually increase the abutting force, thereby achieving the effect of effectively abutting and preventing the first check member 23 from separating from the second check member 32.

[0078] In the first and second embodiments, the connecting portion 25 is a cylinder, and the side surface of the driving member 15 is used to abut against the outer circumference of the cylinder to drive the connecting portion 25. It can be understood that by making the connecting portion 25 a cylinder and the side surface of the driving member 15 abut against the outer circumference of the cylinder, it can be ensured that the driving member 15 smoothly drives the connecting portion 25, so that the rope and line retracting and releasing device 1 smoothly completes the switching from the retracting state to the releasing state.

[0079] In the first and second embodiments, the first engaging portion 12 includes an anti-positive rotation engaging portion 122 and an anti-reverse engaging portion 121. When the rope and line taking-up and releasing device 1 is in the taking-up state, the anti-reverse engaging portion 121 engages with the second engaging portion 22; when the rope and line taking-up and releasing device 1 is in the releasing state, the anti-positive rotation engaging portion 122 engages with the second engaging portion 22. The anti-positive rotation engaging portion 122 and the anti-reverse engaging portion 121 can effectively prevent the rotation phenomenon caused by accidental touch or automatic rebound, thereby improving the reliability of the rope and line taking-up and releasing device 1.

[0080] Furthermore, the number of the second locking parts 22 is at least two and they are distributed in sequence along the circumferential direction, the number of the anti-forward rotation locking parts 122 and the anti-reverse rotation locking parts 121 are both at least two and they are distributed in sequence along the circumferential direction; the number of the first meshing part 24 and the connecting part 25 are both at least two and they are distributed in sequence along the circumferential direction; the number of the first check members 23 and the second check members 32 are at least two and they are distributed in sequence along the circumferential direction; the number of the driving member 15 and the top block 16 is consistent with and corresponds to the number of the connecting part 25; the first check member 23 includes an elastic arm 231 and a first check tooth portion 232 connected to the elastic arm 231, and the second check member 32 includes a plurality of second check tooth portions connected in sequence along the circumferential direction; the first meshing part 24 includes a connecting arm 241 and a first meshing tooth portion 242 connected to the connecting arm 241, and the second meshing part 46 includes a plurality of second meshing tooth portions connected in sequence along the circumferential direction. It can be understood that, by providing the above-mentioned number of the second engaging portion 22, the anti-positive rotation engaging portion 122, the anti-reverse engaging portion 121, the first meshing portion 24, the connecting portion 25, the first non-return member 23, the second non-return member 32, the driving member 15 and the top block 16, the second non-return tooth portion and the second meshing tooth portion, the technical effect of improving the stability and reliability of the rope and line taking-up and releasing device 1 can be achieved. Specifically, the number of the second engaging portion 22, the anti-positive rotation engaging portion 122 and the anti-reverse engaging portion 121 can be two, the number of the first meshing portion 24, the connecting portion, the first non-return member 23, the driving member 15 and the top block 16 can be three, and the number of the second non-return tooth portion and the second meshing tooth portion can be multiple.

[0081] Specifically, Figure 8 and Fig.16As shown, when in the released state, the top block 16 abuts against the first check tooth portion 232 of the first check piece 23, and then the first check piece 23 abuts against and meshes with the second check piece 32. When preventing the forward rotation from starting, the knob 10 and the second check piece 32 start to rotate at the same time. In this case, the driving member 15 and the connecting portion 25 cannot be disengaged or cannot be disengaged, so that the first meshing tooth portion 242 of the first meshing portion 24 temporarily cannot re-engage with the second meshing portion 46 of the wire wheel 40 to achieve rope collection. That is to say, when the top block 16 forcibly abuts the first check tooth portion 232 against the second check piece 32, it will cause us to rotate. When the knob 10 is turned, due to the obstruction of the top block 16, the first check tooth portion 232 cannot rotate and slide out in the second check member 32, resulting in the pawl disk 20 being unable to rotate. In this case, the knob 10 can first be rotated forward by a certain angle (such as the second engaging portion 22 is disengaged from the anti-forward rotation engaging portion 122 and meshed with the anti-reverse rotation engaging portion 121), and at the same time, the driving member 15 and the connecting portion 25 are also rotated by an angle. At this time, the driving member 15 and the connecting portion 25 are disengaged, and the first meshing tooth portion 242 of the first meshing portion 24 can re-engage with the second meshing portion 46 of the reel 40 and then switch to the winding state to achieve rope winding.

[0082] It can be understood that in the knob 10, the side plate 13 is an annular side plate connected to the outer edge of the cover plate 11, and the outer side surface of the side plate 13 also forms an anti-skid structure 131, which can include a plurality of anti-skid grooves extending in a direction perpendicular to the cover plate 11, and the plurality of anti-skid grooves are arranged in a ring along the outer side surface of the side plate 13. By forming the anti-skid structure 131 on the outer side surface of the side plate 13, it can play an anti-skid role when rotating the knob 10, which is convenient for operation. The first stopper 14 can include at least two first extensions 141 extending from the side plate 13 toward the inside; the second stopper 33 includes a second extension 331 protruding from the side wall structure 31 toward the outside, the second extension 331 is an annular structure, and the second extension 331 can extend into the storage space enclosed by the side plate 13 and the cover plate 11 and be clamped and fixed with the first extension 141 adjacent to the side of the cover plate 11. By setting the second extension portion 331 as an annular structure and setting a plurality of first extension portions 141, the second extension portion 331 can be extended into the storage space enclosed by the side plate 13 and the cover plate 11 and can be clamped and fixed with the side of the first extension portion 141 adjacent to the cover plate 11 without being affected by the setting positions of the first extension portion 141 and the second extension portion 331, thereby making operation simpler.

[0083] Further, it can be understood that in the ratchet disk 20, one end of the elastic arm 231 away from the first non-return tooth portion 232 is connected to the outer edge of the base plate 21, and the elastic arm 231 can be deformed to drive the first non-return tooth portion 232 to move in a direction close to the base plate 21 or away from the base plate 21. When the elastic arm 231 is in a natural state, the first non-return tooth portion 232 is away from the base plate 21 and is spaced from the base plate 21. In the base 30, a plurality of second non-return tooth portions are sequentially connected along the first clockwise direction and are arranged around the inner surface of the side wall structure 31, and the second non-return tooth portions are meshed with the first non-return tooth portions 232, and the first non-return tooth portion 232 can rotate relative to the second non-return tooth portions along the first clockwise direction and mesh with different second non-return tooth portions, so that the knob 10 can drive the rotation of the ratchet disk 20, and the operation is simple and the structure is stable. It can be understood that under the action of external force, the first non-return tooth portion 232 can only rotate relative to the second non-return tooth portion along the first clockwise direction (such as clockwise direction) and mesh with the different second non-return tooth portion, and cannot rotate in the opposite direction, thereby achieving the non-return function. In addition, in this embodiment, the first clockwise direction can be clockwise, and the second clockwise direction can be counterclockwise, but it is not limited to the above. In a modified embodiment, the first clockwise direction can also be counterclockwise, and the second clockwise direction can also be clockwise, and the provision of the elastic arm 231 can facilitate the installation of the pawl disk 20.

[0084] In the reel 40, the two substrate parts 42 and the winding part 43 connected between the two substrate parts 42 can form a storage part 49 for storing the rope. The rope can be neatly stored on the reel 40 through the storage part 49 to prevent the rope from being rolled into other positions and affecting other components. Furthermore, the substrate part 42 away from the pawl disk 20 also includes at least one slot 44 connected to the second wire entry hole 45, and the slot 44 is used to accommodate the knot of the rope. By providing the slot 44 to accommodate the knot of the rope, the knot can be limited, effectively avoiding the occurrence of the knot getting stuck, detaching from the reel, etc. It can be understood that the number of the second wire entry hole 45 and the slot 44 can be two, so that the two ends of a rope can be passed through respectively, and the two slots 44 can accommodate the two knots at the two ends.

[0085] Furthermore, the base 30 further includes an extension wall 36 extending from the side wall structure 31 toward the fixing portion, and the extension wall 36 can separate the second check member 32 from the wire wheel 40 to avoid mutual interference; the base 30 further includes a first wire entry portion 37 arranged corresponding to the first wire entry hole 34, and the first wire entry portion 37 includes a first wire entry groove 371 communicating with the first wire entry hole 34, and the width of the first wire entry groove 371 can gradually increase in a direction away from the first wire entry hole 34. It can be understood that the number of the first wire entry hole 34, the first wire entry portion 37, and the second wire entry hole 45 can be set as needed, and usually two are set, and each end of the two ends of the rope can pass through a corresponding first wire entry groove 371 and then pass through a corresponding first wire entry hole 34 and a second wire entry hole 45 and then be set on the wire wheel 40, such as tying a knot so that the rope can still be fixed on the wire wheel 40 when the rope is pulled, and will not fall off. Furthermore, in order to facilitate the knotting of the two ends of the rope after passing through the base 30, the base 30 may also include a through hole 38 penetrating the side wall structure 31, and each end of the rope may pass through a corresponding first wire entry slot 371 and then through a corresponding first wire entry hole 34, a second wire entry hole 45 and then through the through hole 38, so as to be exposed outside the base 30, and each end of the rope may be knotted at this time. It can be understood that the gradually increasing width of the first wire entry slot 371 in the direction away from the first wire entry hole 34 makes the wire collection and release operations more convenient.

[0086] The chassis 50 is also fixed with the base 30 by snapping; the chassis 50 may include a bottom plate 51, on which a first snap groove 52 and a second snap groove 53 are formed, the first snap groove 52 and the second snap groove 53 are arranged at intervals, the base 30 also includes a first clip 311 and a second clip 312 connected to the outer side of the side wall structure 31, the first clip 311 and the second clip 312 are arranged at intervals and correspond to the first clip groove 52 and the second clip groove 53 respectively, the first clip 311 can extend into the first clip groove 52 and snap into the side of the bottom plate 51 away from the base 30, the second clip 312 can extend into the second clip groove 53 and snap into the side of the bottom plate 51 away from the base 30; the first clip 311 and the second clip 312 are both arc-shaped, and the first clip groove 52 and the second clip groove 53 are both arc-shaped. The chassis 50 further includes a side wall portion 54 connected to the bottom plate 51 adjacent to the base 30 . The side wall portion 54 and the bottom plate 51 together accommodate at least a portion of the side wall structure 31 . The side wall portion 54 further has a notch corresponding to the first wire entry hole 34 .

[0087] By setting the first snap groove 52 and the second snap groove 53 on the bottom plate 51, the first snap member 311 and the second snap member 312 are set on the outer side of the side wall structure 31, the first snap member 311 can extend into the first snap groove 52 and snap into the side of the bottom plate 51 away from the base 30, the second snap member 312 can extend into the second snap groove 53 and snap into the side of the bottom plate 51 away from the base 30, and the side wall portion 54 and the bottom plate 51 jointly accommodate at least a part of the side wall structure 31, so that the overall structure is compact, which is beneficial to the miniaturization and lightweight of the rope and line retracting device 1, and can also improve the stability of the overall structure.

[0088] like Figures 1 to 8 As shown, in the first embodiment, the knob 10 includes a protruding structure 17 disposed in the middle area of ​​the cover plate 11, the anti-positive rotation engaging portion 122 and the anti-reverse engaging portion 121 are grooves 123 sequentially formed on the outer side of the protruding structure 17, the base plate 21 includes a groove structure 211 disposed in the middle area, the second engaging portion 22 includes a hook 221 extending into the groove structure 211, and the hook 221 is used to engage with the groove 123 of the anti-positive rotation engaging portion 122 or the groove 123 of the anti-reverse engaging portion 121. Since the hook 221 and the groove structure 211 are simple and highly reliable, the cooperation of the hook 221 and the groove 123 can stably prevent the rotation phenomenon caused by mis-touch or automatic rebound, thereby improving the reliability of the rope and line retracting device 1.

[0089] In the first embodiment, a first limiting portion 171 is further provided on the outer side surface of the protrusion structure 17, and a second limiting portion 212 is further provided on the side wall surface of the groove structure 211. One of the first limiting portion 171 and the second limiting portion 212 is a limiting block, and the other of the first limiting portion 171 and the second limiting portion 212 is a limiting slide groove. The limiting block is used to slide in the limiting slide groove to limit the relative rotation angle between the knob 10 and the pawl disk 20, so that the anti-forward rotation engaging portion 122 and the anti-reverse rotation engaging portion 121 of the knob 10 are engaged or disengaged with the second engaging portion 22 of the pawl disk 20 in sequence. It can be understood that since the limit block and the limit slot have a simple structure and high reliability, the relative rotation angle between the knob 10 and the pawl disk 20 can be limited through the cooperation of the limit block and the limit slot, so that the anti-forward rotation engaging portion 122 and the anti-reverse rotation engaging portion 121 of the knob 10 are engaged or disengaged with the second engaging portion 22 of the pawl disk 20 in turn, thereby improving the stability of the rope retracting device 1 and the user experience.

[0090] In the first embodiment, the groove 123 includes a first surface 124 and a second surface 125 connected by a bend, and the protruding structure 17 has an arc surface connecting the first surface 124 and the second surface 125. The angle of the tangent of the connection point of the first surface 124 and the part of the arc surface connected thereto is different from the angle of the tangent of the connection point of the second surface 125 and the part of the arc surface connected thereto, so that the external force required for the hook 221 to disengage from the groove 123 of the anti-positive rotation engaging portion 122 is less than the external force required for the hook 221 to disengage from the groove 123 of the anti-reverse engaging portion 121. It can be understood that, through the arrangement of the above structure, the external force required for the hook 221 to disengage from the groove 123 of the anti-positive rotation engaging portion 122 is less than the external force required for the hook 221 to disengage from the groove 123 of the anti-reverse engaging portion 121, thereby improving the user experience.

[0091] like Figures 9 to 16 As shown, in the second embodiment, the anti-positive rotation engaging portion 122 and the anti-reverse engaging portion 121 are grooves 123 sequentially arranged on the cover plate 11 along the circumferential direction, and the second engaging portion 22 is a block 225 arranged on the winding portion 43, and the block 225 is used to engage with the groove 123 of the anti-positive rotation engaging portion 122 or the groove 123 of the anti-reverse engaging portion 121. Since the block 225 and the groove structure 211 are simple and highly reliable, the cooperation of the block 225 and the groove 123 can stably prevent the rotation phenomenon caused by mis-touch or automatic rebound, thereby improving the reliability of the rope and line retracting device 1.

[0092] In the second embodiment, a first limiting portion 171 is further provided on one side of the cover plate 11, and a second limiting portion 212 is further provided on the side of the winding portion 43 close to the cover plate 11, one of the first limiting portion 171 and the second limiting portion 212 is a limiting block, and the other of the first limiting portion 171 and the second limiting portion 212 is a limiting slide groove, and the limiting block is used to slide in the limiting slide groove to limit the relative rotation angle of the knob 10 and the pawl disk 20, so that the anti-forward rotation engaging portion 122 and the anti-reverse rotation engaging portion 121 of the knob 10 are engaged or disengaged with the second engaging portion 22 of the pawl disk 20 in sequence; the number of the first limiting portion 171 and the second limiting portion 212 is at least two and is distributed along the circumferential direction. It can be understood that since the limit block and the limit slot have a simple structure and high reliability, the relative rotation angle between the knob 10 and the pawl disk 20 can be limited through the cooperation of the limit block and the limit slot, so that the anti-forward rotation engaging portion 122 and the anti-reverse rotation engaging portion 121 of the knob 10 are engaged or disengaged with the second engaging portion 22 of the pawl disk 20 in turn, thereby improving the stability of the rope retracting device 1 and the user experience.

[0093] In the second embodiment, the groove 123 includes a first surface 124 and a second surface 125 that are bent and connected, and the angle between the main body surface on one side of the cover plate 11 and the first surface 124 is different from the angle between the main body surface on one side of the cover plate 11 and the second surface 125, so that the external force required for the block 225 to disengage from the groove 123 of the anti-normal rotation engaging portion 122 is less than the external force required for the block 225 to disengage from the groove 123 of the anti-reverse engaging portion 121. It can be understood that, through the arrangement of the above structure, the external force required for the block 225 to disengage from the groove 123 of the anti-normal rotation engaging portion 122 is less than the external force required for the block 225 to disengage from the groove 123 of the anti-reverse engaging portion 121, thereby improving the user experience.

[0094] In the second embodiment, the axial height of the block 225 along the direction from the knob 10 to the pawl disk 20 is less than the height of the limit block along the axial height, which can ensure that when the block 225 is engaged and switched with different grooves 123, the knob 10 and the pawl disk 20 remain connected and their relative positions are restricted to prevent excessive rotation of the knob.

[0095] The installation and use process of the rope and line retracting device 1 according to the first embodiment and the second embodiment are described below.

[0096] First, during installation, the pawl disk 20 can be installed with the base 30 first to ensure that the first check tooth portion 232 of the first check member 23 is correctly engaged with the second check member 32, and then the knob 10 is set according to the anti-positive rotation engagement, and the second engagement portion 22 is engaged with the anti-positive rotation engagement portion 122 to be in the winding state, and then the knob 10 is rotated in the opposite direction to the released state, and then the base 30 is installed, and the reel 40 is pressed in from the bottom, and then the knob 10 is rotated forward for about one circle, which completes the assembly of the main structure of the rope and line taking-up device 1, and finally the chassis 50 is installed, wherein the chassis 50 can be set on an object body having a rope (such as a shoe), one end of the rope can pass through the first wire entry hole 34 of the base 30 and the second wire entry hole 45 of the reel 40, and can be tied so that the knot is accommodated in the reel 40. It can be understood that after installation, the rope and line taking-up device 1 can be in the winding state.

[0097] When the user is using the rope and wire retracting device 1, when the rope needs to be tightened, the user can rotate the knob 10 along the first clockwise direction, and the knob 10 can drive the pawl disk 20 to rotate, and then the pawl disk 20 drives the wire wheel 40 to rotate, so that the rope and wire retracting device 1 is in a wire-retracting state and the rope can be wound around the winding part 43 to retract the rope, and due to the cooperation between the first check member 23 and the second check member 32, the pawl disk 20 cannot automatically rotate in the opposite direction, and the wire wheel 40 will not automatically rotate in the opposite direction, so that the rope can be wound around the wire wheel 40 to retract the rope; when the knob 10 stops rotating, the anti-reverse engaging part 121 engages with the second engaging part 22, and the knob 10 will not automatically reverse or rotate forward when sufficient reversal force is not applied to it.

[0098] When an external force of a certain strength is applied to rotate the knob 10 in the reverse direction, the anti-reversal engaging portion 121 disengages from the second engaging portion 22, and the knob 10 can be reversed. When the knob 10 is reversed, the inner side surface 161 of the driving member 15 presses back on the outer side surface of the connecting portion of the pawl disk 20, forcing the second engaging portion 46 to move inward and disengage from the first engaging portion 24, so that the rope retracting device 1 is in a released state, so that the reel 40 can freely reverse in the base 30 to realize the release of the rope, that is, the rope can be pulled out from the reel 40 at this time. Furthermore, when the second meshing portion 46 moves inward and disengages from the first meshing portion 24, the second engaging portion 22 of the pawl disk 20 can just engage with the anti-positive rotation engaging portion 122, and the first limiting portion 171 and the second limiting portion 212 abut against each other to prevent the knob 10 from being excessively reversed. The anti-positive rotation engaging portion 122 engages with the second engaging portion 22 to prevent the knob 10 from automatically rotating forward and releasing the second engaging portion 22 in the absence of external force, thereby ensuring that the pawl disk 20 and the reel 40 are engaged and the rope is not pulled out freely.

[0099] It can be understood that the top block 16 can abut against the inner side of the first check piece 23 and the winding part 43 in the released state to prevent the first check piece 23 from disengaging from the second check piece 32, so that the pawl disk 20 can be engaged with the base 30, but disengaged from the wire wheel 40, which means that the pawl disk 20 cannot rotate with the knob 10, but the knob 10 can continue to rotate along the first clockwise direction under a certain external force. When the top block 16 rotates a certain angle with the knob 10 (such as the second engaging part 22 disengages from the anti-forward rotation engaging part 122 and engages with the anti-reverse rotation engaging part 121), it can be dislocated and separated from the second check piece 32. At this time, the first check piece 23 can rotate relative to the second check piece 32. At this time, the rope and line taking-up device 1 can enter the winding state, that is, the knob 10 can drive the pawl disk 20 and the wire wheel 40 to rotate forward to achieve the storage of the rope.

[0100] Furthermore, if Fig.17 , Fig.18 , Fig.19 and Fig. 20As shown, the third embodiment of the present application provides a rope and line retracting device 1, and the rope and line retracting device 1 of the third embodiment is basically the same as the rope and line retracting device 1 of the first embodiment. The following mainly describes the differences between the two. In the third embodiment, the driving member 15 may include a driving body 151 and a stopper 152 connected to the driving body 151, and the side of the driving body 151 is used to abut the outer peripheral surface of the top block 16 to drive the connecting portion 25; the stopper 152 is connected to one end of the driving body 151 and is bent toward the center of the knob 10. The angle between the stopper 152 and the driving body 151 can be an obtuse angle, which is used to stop the connecting portion 25 after driving the connecting portion 25 to prevent the first meshing portion 24 from sliding out to the outside of the driving member 15, thereby causing the phenomenon that the release state cannot be achieved. The connecting portion 25 also includes an extension block 252 connected to the cylinder 251, and the extension block 252 is used to abut the top block 16 in the release state.

[0101] In the third embodiment, a plurality of alignment installation points 301 are further provided on the top surface of the side wall structure 31 of the base 30, and the alignment installation points 301 are used to assist the installation of the pawl disk 20. Specifically, the number of the alignment installation points 301 can be consistent with the number of the first check members 23 and the positions of the two correspond to each other, so as to facilitate the installation of the pawl disk 20 and the base 30.

[0102] Furthermore, it can be understood that Fig.19 As shown, the inner angle of the hook 221 is an acute angle, which is used to increase the buckling strength of the hook 221.

[0103] Furthermore, if Fig.21 , Fig. 22 , Fig.23 and Fig.24As shown, the fourth embodiment of the present application provides a rope and line retracting device 1, and the rope and line retracting device 1 of the fourth embodiment is basically the same as the rope and line retracting device 1 of the first embodiment. The following mainly describes the differences between the two. In the fourth embodiment, the driving member 15 may include a driving body 151 and a stopper 152 connected to the driving body 151, and the side of the driving body 151 is used to abut the outer peripheral surface of the top block 16 to drive the connecting portion 25; the stopper 152 is connected to one end of the driving body 151 and is bent toward the center of the knob 10. The angle between the stopper 152 and the driving body 151 can be an obtuse angle, which is used to stop the connecting portion 25 after driving the connecting portion 25 to prevent the first meshing portion 24 from sliding out to the outside of the driving member 15, thereby causing the phenomenon that the release state cannot be achieved. The connecting portion 25 also includes an extension block 252 connected to the cylinder 251, and the extension block 252 is used to abut the top block 16 in the release state.

[0104] In the fourth embodiment, a plurality of alignment installation points are further provided on the top surface of the side wall structure 31 of the base 30, and the alignment installation points are used to assist the installation of the pawl disk 20. Specifically, the number of the alignment installation points can be consistent with the number of the first check members 23 and the positions of the two correspond to each other, so as to facilitate the installation of the pawl disk 20 and the base 30.

Moreover, the small number of components can also improve the stability of the overall structure, and improve the reliability and service life of the rope and wire retracting device 1.
