The locking edge can lock the shaft locking part and the upper part of the seat side wall together, and on the basis of ensuring the free rotation of the rope winding shaft, the rope winding shaft can be prevented from escaping from the storage seat, especially preventing the wound rope from supporting the rope winding shaft and escaping from the storage seat. The clutch drive part drives the winding shaft body by driving teeth or driving through holes that match the passive teeth of the winding shaft body. The cover shaft achieves axial limitation by matching the third axial limiting part with the second axial limiting part of the rope winding shaft, and limits the relative axial position of the cover body and the rope winding shaft. The rope retracting and releasing state can also be switched by snapping the third axial limiting part with the second axial limiting part at different axial positions. Compared with the prior art, the new rope retracting and releasing device of the utility model has the advantages of simple structure and high strength, easy demoulding, simple processing and assembly process, low cost, simple assembly, small rotation contact surface, stable working performance, smooth and efficient operation, reasonable and practical structure, etc. BRIEF DESCRIPTION OF THE DRAWINGS

The claw teeth fluctuate in the direction of approaching or moving away from the shaft side teeth; when the rotation of the cover body stops, the claw teeth rely on the corresponding claw clamping surface on the claw teeth to clamp the shaft side teeth and position the winding shaft body, so that the rope object is wound on the winding shaft body with a corresponding tightness and it is difficult to reverse and loosen the rope object; when the top driving part of the rotary cover does not apply pressure to the seat clamping claw, the claw teeth move outward and disengage from the shaft side teeth under the deformation recovery of the elastic claw arm, and the claw teeth do not clamp the shaft side teeth. The rope object can be loosened by actively rotating the cover body in the opposite direction or by using the tension of the rope object itself to drive the winding shaft body to rotate in the opposite direction. On the basis of realizing smooth and stable retraction and release of the rope object, the rope winding shaft uses the shaft side teeth to replace the traditional cover tooth structure, which is simple to mold and easy to demold, avoiding the problem that the traditional cover tooth structure is formed on the inner side of the cover body and is difficult to demold due to space limitations and other factors, significantly reducing the process difficulty, improving processing efficiency, reducing costs, and having higher strength than the cover tooth structure.The locking edge can lock the shaft locking portion and the upper position of the seat side wall together, and on the basis of ensuring the free rotation of the rope winding shaft, it can prevent the rope winding shaft from escaping from the storage seat, especially preventing the wound rope from propping up the rope winding shaft and detaching it from the storage seat.

The clutch drive unit drives the winding shaft body by using driving teeth or driving through holes that cooperate with the passive teeth of the winding shaft body. The cover shaft cooperates with the second axial limiting portion of the rope winding shaft through the third axial limiting portion to achieve axial limiting, and limits the relative axial position of the cover body and the rope winding shaft. The rope retracting and releasing state can also be switched by locking the third axial limiting portion with the second axial limiting portion at different axial positions.

[0082] In another embodiment, the second axial limiting portion 261 includes an in-hole protrusion formed in the shaft hole 26. The second axial limiting portion 261 is snap-fitted with a corresponding protrusion or depression of the cover shaft 16 through the in-hole protrusion. The in-hole protrusion and the corresponding protrusion or depression of the cover shaft 16 can also be snap-fitted at different axial positions to achieve the switching of the rope retracting and releasing states.

[0083] In another embodiment, the protrusion in the hole is a protruding ring. This structure facilitates the protrusion in the hole to snap fit with the corresponding protrusion or recess of the cover shaft 16, and also enables the shaft hole 26 and the cover shaft 16 to have a relative rotation effect.

[0084] In another embodiment, the protrusion in the hole is a full circle of protrusions around the axis of the rope winding shaft.

Moreover, different buckle positions or a combination of a buckle function and an anti-slipping function are formed under the cooperation of the first anti-slipping head 1615 and the second protruding head 1612.

[0097] In another embodiment, the first anti-slip head 1615 is closer to the lower end of the cover shaft 16 than the second protrusion 1612. This structure allows the first anti-slip head 1615 and the second protrusion 1612 to cooperate with the same protrusion in the hole to achieve their respective functions, without the need for two protrusions in the hole, and the structure is simple and compact, which is easy to process.

[0098] In another embodiment, the first anti-slip head 1615 has a second limiting end surface 16151 facing the second protruding head 1612. When the second protruding head 1612 passes through the corresponding narrow portion of the shaft hole 26, the first anti-slip head 1615 is hooked and pressed against the lower end of the corresponding narrow portion of the shaft hole 26 through the second limiting end surface 16151 to prevent the cover shaft 16 from slipping off the rope winding shaft.

[0099] In another embodiment, the plane where the second limiting end surface 16151 is located is perpendicular to the axis of the cover shaft 16. This structure is conducive to the use of injection molding and other processes to form the structure while ensuring that the corresponding part of the rope winding shaft is not easy to fall out after being buckled.

[0100] In another embodiment, the first anti-slip head 1615 has a second inclined surface 16152 facing the bottom of the storage seat, and the second inclined surface 16152 gradually tilts from the root to the end toward the cover body 1. This structure facilitates the first anti-slip head 1615 to be inserted into the corresponding narrow part of the rope winding shaft and buckled.

[0101] In another embodiment, the outer side of the seat side wall 31 is formed with a seat stopper 34 facing the cover side wall 13. The seat stopper 34 can cooperate with the cover stopper 131 to prevent the cover body 1 from separating from the seat body 3, and keep the cover body 1 and the seat body 3 within the working range.

[0102] In another embodiment, the outer diameter of the seat limiting portion 34 is larger than the inner diameter of the cover limiting portion 131. This structure can ensure that after the cover body 1 is sleeved on the seat body 3, the cover limiting portion 131 and the seat limiting portion 34 are assembled by extrusion deformation, and ensure that the assembled cover limiting portion 131 and the seat limiting portion 34 have a large limiting corresponding surface and are not easy to be disengaged.

[0103] In another embodiment, an inclined surface which gradually slopes downward from the inner circle to the outer circle is formed on the upper part of the seat stopper 34. This structure facilitates the assembly of the cover stopper 131 and the seat stopper 34 by extrusion deformation.

[0104] In another embodiment, the seat clamping claw 32 is integrally formed with the seat side wall 31. The seat clamping claw 32 and the seat side wall 31 are integrally formed to ensure the overall structural strength and elastic working performance stability, reduce assembly processes and have low one-time molding costs. The seat clamping claw 32 and the seat side wall 31 can be specifically made of resin materials such as ABS. Moreover, the elastic claw arm 321, the claw teeth 322 and the top portion 3211 to be pressed are an integrally formed structure to ensure strength and molding efficiency.

[0105] In another embodiment, the seat body 3 includes a seat clamping portion 33 that is matched and buckled with the shaft clamping portion 24; the seat clamping portion 33 includes a seat clamping groove 331 for the clamping edge 241 to be clamped into; the seat clamping groove 331 is located at the upper part of the seat side wall 31 and is lower than the elastic claw arm 321; there is a forming gap 35 between the seat side wall 31 and the elastic claw arm 321, the seat clamping groove 331 is located at the root of the elastic claw arm 321, and the upper edge of the seat clamping groove 331 is lower than the upper edge of the forming gap 35. This structure facilitates the clamping edge 241 to be lower than the elastic claw arm 321 after being clamped with the seat clamping groove 331, and will not hinder the deformation of the elastic claw arm 321, and when the rope is wound around the shaft and rotated, the clamping edge 241 will not scratch the elastic claw arm 321, ensuring smooth rotation and the movement of the elastic claw arm 321. The specific structure can be that the lower side of the seat clamping groove 331 is at the same height as the lower side of the deformation gap. This structure is convenient for molding, is conducive to the rotational cooperation of the rope winding shaft, and has a compact structure. The molding gap 35 is conducive to demoulding the seat claw 32 which is integrated with the seat body 3.

[0106] In another embodiment, the upper shaft end wall 23 has a corresponding peripheral surface corresponding to the inner side of the seat side wall 31, and the shaft side teeth 21 are formed on the corresponding peripheral surface. This structure facilitates the shaft side teeth 21 to correspond to the seat claws 32 on the upper part of the seat side wall 31, does not affect the winding of the rope inside, and can avoid the shaft part 22 to facilitate molding, with a compact structure and high strength.

[0107] In another embodiment, the extension direction of the shaft side teeth 21 is parallel to the axis of the winding shaft body 2. That is, each shaft side tooth 21 is arranged along the direction of the axis of the winding shaft body 2, and the extension direction of the length of a single shaft side tooth 21 is parallel to the axis of the winding shaft body 2. This structure facilitates the engagement and limiting of the shaft side teeth 21 and the claw teeth 322 in the direction of the winding shaft body 2, and does not generate a component force along the axis of the winding shaft body 2, thereby ensuring the coordination between the shaft side teeth 21 and the claw teeth 322 and the stability and smoothness of the rotation of the winding shaft body 2.

[0108] In another embodiment, the shaft side teeth 21 gradually extend from the root to the tip toward the direction of unwinding the rope. This structure facilitates the shaft side teeth 21 and the claw teeth 322 to smoothly rotate relative to each other toward the direction of tightening the rope, and when the winding shaft body 2 rotates toward the direction of unwinding the rope, the two will be stuck together, so that the two have an obvious one-way rotation effect.

[0109] In another embodiment, the shaft side teeth 21 are located above the shaft clamping portion 24. This structure facilitates the shaft side teeth 21 to cooperate with the seat clamping claw 32, and the shaft clamping portion 24 to cooperate with the retractable seat. The specific structure can be that the shaft side teeth 21 and the shaft clamping portion 24 are as close as possible.

[0110] In another embodiment, the diameter of the circle where the tip of the shaft side teeth 21 is located is smaller than the diameter of the circle where the shaft locking portion 24 is located. This structure facilitates the shaft locking portion 24 to be more protruding and easily extend into the seat side wall 31 for locking.

[0111] In another embodiment, the locking edge 241 is a full circle around the axis of the winding shaft body 2. This structure facilitates the rope winding shaft to rotate while maintaining the locking with the retracting seat. In this case, the seat locking portion 33 can be a complete ring or a segmented form, which is convenient for selecting a method for the seat locking portion 33 to be easily formed.

[0112] In another embodiment, the locking edge 241 is two or more edge monomers arranged around the axis of the winding shaft body 2. This structure facilitates the rope winding shaft to rotate while maintaining the locking with the retracting seat. In this case, the seat locking portion 33 can be a complete ring.

[0113] In another embodiment, the locking edge 241 is located below the shaft side teeth 21 and protrudes further toward the seat side wall 31 than the shaft side teeth 21. This structure facilitates the corresponding cooperation between the shaft side teeth 21 and the seat clamping claws 32, facilitates the corresponding cooperation between the locking edge 241 and the seat clamping portion 33, and the shaft clamping portion 24 is more protruding and easy to extend into the seat clamping portion 33 in the form of a groove for locking.

[0114] In another embodiment, the locking edge 241 has a downwardly facing axis locking inclined surface 242, which gradually tilts from top to bottom toward the axis direction of the rope winding axis body 2. This structure facilitates the winding axis body 2 to be locked into the seat body 3 by using the locking inclined surface, and the locking edge 241 is locked into the seat locking portion 33 for positioning.

[0115] In another embodiment, the locking edge 241 has an upward locking surface 243. When the locking edge 241 is locked into the seat locking portion 33, the locking surface 243 and the corresponding locking surface of the seat locking portion 33 above the locking surface 243 abut against each other to prevent the locking edge 241 from falling out.

[0116] In another embodiment, the plane where the stop surface 243 is located is perpendicular to the axis of the winding shaft body 2. This structure can ensure the buckling stability between the stop surface 243 and the corresponding clamping surface of the seat clamping portion 33, and facilitate demoulding.

[0117] In another embodiment, the claw teeth 322 have a mating position where they are in contact with the shaft side teeth 21, and a disengaging position where they are disengaged from the shaft side teeth 21. In the mating position, the claw teeth 322 are in contact with the shaft side teeth 21, and the rotating cover is rotated in the direction of tightening the rope to drive the winding shaft body 2 to rotate, and the shaft side teeth 21 can be engaged with the claw teeth 322 and rotate relatively, and have a reverse locking effect, and the winding shaft body 2 cannot be reversed to loosen the rope; in the disengaging position, the claw teeth 322 are disengaged from the shaft side teeth 21, and the shaft side teeth 21 are not limited by the claw teeth 322, and the winding shaft body 2 can be reversed to loosen the rope.

[0118] In another embodiment, the elastic claw arm 321 gradually extends from the root to the free end in the direction of tightening the rope. The elastic claw arm 321 of this structure is easy to produce lateral deformation when subjected to the force in the direction of tightening the rope, which is more conducive to the rotation of the shaft side teeth 21 in the direction of tightening the rope, and when the winding shaft body 2 applies pressure to the claw teeth 322 in the direction of preventing the rope from loosening, the elastic claw arm 321 uses its own supporting force to support the claw teeth 322 against the shaft side teeth 21 to prevent reversal, which is conducive to the unidirectional rotation of the winding shaft body 2.

[0119] In another embodiment, the claw teeth 322 gradually extend from the root to the tip toward the direction of tightening the rope. This structure facilitates the smooth relative rotation of the shaft side teeth 21 and the claw teeth 322 toward the direction of tightening the rope, and when the winding shaft body 2 rotates toward the direction of loosening the rope, the two will be stuck together, so that the two have an obvious one-way rotation effect.

[0120] In another embodiment, the abutted top portion 3211 is a protrusion protruding outwards. This structure is beneficial for the abutted top portion 3211 in the form of a protrusion to be closer to the abutting driving portion 11 of the rotary cover and to be easily driven by the abutting.

[0121] In another embodiment, the protrusion protrudes from the annular surface of the seat body 3. This structure facilitates the abutted top portion 3211 in the form of a protrusion to be closer to the abutting driving portion 11 of the rotary cover on the entire corresponding annular surface of the seat body 3, so that it is easy to be abutted and driven by the abutting driving portion 11 at any position.

[0122] In another embodiment, the protrusion has a sliding surface 32111 for the pressing driving part 11 of the cover body 1 to press, and the sliding surface 32111 is gradually tilted outward from top to bottom. This structure is conducive to the pressing driving part 11 pressing the pressed top part 3211 when the rotating cover moves toward the storage seat, driving the pressed top part 3211 and the seat claw 32, ensuring the smoothness and stability of the movement.

[0123] In another embodiment, the protrusion includes a pressed surface 32112 below the sliding surface 32111. When the abutting driving part 11 of the rotary cover passes the sliding surface 32111, it can abut against the pressed surface 32112 to stabilize the protrusion, ensuring the stability of the matching between the claw teeth 322 and the shaft side teeth 21.

[0124] In another embodiment, the outer side surface of the pressed surface 32112 is parallel to the axis of the winding shaft body 2. This structure allows the abutting driving part 11 of the rotary cover to smoothly contact the pressed surface 32112, and facilitates the rotary cover to smoothly move toward or away from the retractable seat.

[0125] In another embodiment, the outer side surface of the pressed surface 32112 gradually tilts from top to bottom toward the winding shaft body 2. This structure allows the pressing driving part 11 of the rotary cover to be positioned by the pressed surface 32112 after passing the sliding surface 32111, generating a component force toward the retractable seat for the pressing driving part 11 and the rotary cover, thereby preventing the rotary cover from falling out easily.

[0126] In another embodiment, the seat side wall 31 is provided with a seat clamping portion 33 that cooperates with the shaft clamping portion 24 to prevent the winding shaft body 2 from escaping. This structure allows the retractable seat to be clamped together with the shaft clamping portion 24 through the seat clamping portion 33, and on the basis of ensuring the free rotation of the rope winding shaft, the rope winding shaft can be prevented from escaping from the retractable seat, especially to prevent the wound rope from supporting the rope winding shaft and escaping from the retractable seat. The shaft clamping portion 24 can be a full circle of protrusions or grooves, which facilitates the rotation of the rope winding shaft while maintaining the clamping with the seat clamping portion 33. At this time, the seat clamping portion 33 can be a full circle or a segmented form. When the seat clamping portion 33 is a complete ring, the shaft clamping portion 24 can be a full circle or a segmented form. This structure can also ensure that the rope winding shaft rotates while maintaining the clamping with the retractable seat.

[0127] In another embodiment, the seat clamping portion 33 is a protrusion that cooperates with the shaft clamping portion 24. The seat clamping portion 33 blocks and limits the shaft clamping portion 24 in the form of a protrusion or a groove through the protrusion to prevent the rope from being wrapped around the shaft and escaping from the retracting seat.

[0128] In another embodiment, the seat clamping portion 33 is a groove that cooperates with the shaft clamping portion 24. The seat clamping portion 33 blocks and limits the shaft clamping portion 24 in the form of a protrusion or a groove through the groove to prevent the rope from being wrapped around the shaft and escaping from the retracting seat.

[0129] In another embodiment, the seat clamping portion 33 includes a seat clamping groove 331 for the clamping edge 241 to be clamped in. The seat clamping portion 33 accommodates and blocks the protruding shaft clamping portion 24 through the seat clamping groove 331 to prevent the rope from being wrapped around the shaft and escaping from the retracting seat.

[0130] In another embodiment, the seat clamping groove 331 has a groove upper wall 3311 located at the top. The groove upper wall 3311 is mainly used to resist and limit the protruding shaft clamping portion 24 to prevent the shaft clamping portion 24 from falling out.

[0131] In another embodiment, the distance from the groove upper wall 3311 to the rotation axis of the rope winding shaft is smaller than the radius of the locking edge 241. This structure can ensure that the shaft locking portion 24 is blocked and limited by the groove upper wall 3311 after being locked into the seat locking groove 331.

[0132] In another embodiment, the upper end of the groove upper wall 3311 has a seat clamping inclined surface 3312 for the clamping edge 241 to slide into the seat clamping groove 331. When a certain force toward the retracting seat is applied to the winding shaft body 2 or the shaft clamping portion 24, the shaft clamping portion 24 can slide into the seat clamping groove 331 through the seat clamping inclined surface 3312 and be locked and limited.

[0133] In another embodiment, the seat clamping inclined surface 3312 gradually tilts from top to bottom toward the axis of the rope winding shaft. This structure can ensure that the shaft clamping portion 24 slides into the seat clamping groove 331 through the seat clamping inclined surface 3312 and is locked.

[0134] In another embodiment, the groove upper wall 3311 is closer to the rotation axis of the winding shaft body 2 than the inner side of the elastic claw arm 321. This structure can make the groove upper wall 3311 at least closer to the winding shaft body 2 than the elastic claw arm 321 in the relaxed state, and on the basis of the seat clamping groove 331 limiting the shaft limiting part, it can ensure that there is a gap between the elastic claw arm 321 and the winding shaft body 2 for the elastic claw arm 321 to move.

[0135] In another embodiment, the seat clamping groove 331 is located at the upper part of the seat side wall 31 and is lower than the elastic claw arm 321. This structure facilitates the clamping edge 241 to be lower than the elastic claw arm 321 after being locked with the seat clamping groove 331, and will not hinder the deformation of the elastic claw arm 321. Moreover, when the rope is wound around the shaft and rotated, the clamping edge 241 will not scratch the elastic claw arm 321, ensuring smooth rotation and movement of the elastic claw arm 321.

[0136] In another embodiment, the seat clamping groove 331 is located at the root of the elastic claw arm 321. This structure can ensure the strength of the seat clamping groove 331 and its limiting strength to the clamping edge 241. The specific structure can be that the seat clamping groove 331 is arranged on the main body of the seat side wall 31.

[0137] In another embodiment, the inner side surface of the elastic claw arm 321 is further away from the rotation axis of the winding shaft body 2 than the inner side surface of the seat side wall 31. This structure facilitates the elastic claw arm 321 to have sufficient inward deformation space, and the seat side wall 31 has sufficient thickness to form the seat clamping groove 331, which is conducive to demoulding and ensures that the clamping edge 241 does not affect the deformation of the elastic claw arm 321, and when the rope winding shaft rotates, the clamping edge 241 will not scratch the elastic claw arm 321, ensuring smooth rotation and movement of the elastic claw arm 321.

[0138] In another embodiment, the inner side surface of the elastic claw arm 321 is farther from the axis of the winding shaft body 2 than the inner side surface of the seat side wall 31 by a greater distance than the depth of the seat clamping groove 331. This structure ensures that the clamping edge 241 will not interfere with the elastic claw arm 321 when rotating, and the mold of the seat clamping groove 331 is easy to demould from the elastic claw arm 321 after rotating a certain angle.

[0139] In another embodiment, the inner side surfaces of the groove upper wall 3311 and the seat side wall 31 are at equal distances from the axis of the rope winding shaft. This structure is convenient for molding.

[0140] In another embodiment, the abutting driving part 11 includes an abutting inclined surface 111 for pressing the elastic claw arm 321, and the abutting inclined surface 111 gradually tilts from top to bottom in a direction away from the winding shaft body 2. This structure facilitates the cover body 1 to abut the abutted top portion 3211 of the retractable seat through the abutting inclined surface 111 when the cover body 1 moves toward the retractable seat, thereby driving the abutted top portion 3211 and the seat claw 32, thereby ensuring smooth and stable movement.

[0141] In another embodiment, the cover body 1 includes a cover plate 12 and a cover side wall 13 at the edge of the cover plate 12 and extending toward the storage seat; a top-resisting inclined surface 111 is formed on the inner side of the cover side wall 13. This structure facilitates the top-resisting inclined surface 111 to drive the seat claw 32 accordingly.

[0142] In another embodiment, the abutting driving part 11 includes an abutting pressing surface 112 located above the abutting inclined surface 111. When the abutted top part 3211 of the seat clamping claw 32 passes through the abutting inclined surface 111, it can abut on the abutting pressing surface 112, and the abutting driving part 11 stabilizes the protrusion through the abutting pressing surface 112 to ensure the stability of the matching between the claw teeth 322 and the shaft side teeth 21.

[0143] In another embodiment, the abutting pressure surface 112 is parallel to the axis of the winding shaft body 2. This structure allows the abutting driving part 11 of the rotary cover to smoothly contact the abutted top part 3211 of the seat claw 32, and facilitates the rotary cover to smoothly move closer to or away from the retractable seat.

[0144] In another embodiment, the pressing surface 112 gradually tilts from top to bottom toward the winding shaft body 2. This structure allows the pressed top portion 3211 of the seat claw 32 to be positioned by the pressing surface 112 after passing through the pressing inclined surface 111, thereby generating a force to bring the cover body 1 and the retractable seat closer together, thereby preventing the cover from being easily dislodged.

[0145] In another embodiment, the abutting driving part 11 is a protruding step toward the winding shaft body 2. The abutting driving part 11 of this structure is conducive to contacting the abutted part 3211 of the seat clamping claw 32 and abutting and driving it.

[0146] In another embodiment, the inner side surface of the cover side wall 13 is formed with a cover stopper 131 facing the winding shaft body 2. The cover stopper 131 can cooperate with the seat stopper 34 of the retractable seat to limit the cover body 1 and the seat body 3, maintain the working state of the cover body 1 and the seat body 3 or prevent the cover body 1 and the seat body 3 from being separated.

[0147] In another embodiment, there is a slot 132 between the abutting driving part 11 and the cover stopper 131 for accommodating the seat stopper 34. This structure facilitates the cooperation between the cover stopper 131 and the seat stopper 34 and provides space for relative movement between the cover body 1 and the seat body 3 when the retracting and extending action is switched, thereby ensuring the smoothness and stability of the switching of the retracting and extending action.

[0148] In another embodiment, the cover stopper 131 is located below the abutting driving part 11. This structure facilitates the seat stopper 34 to be disposed below the seat clamping claw 32, so that the seat stopper 34 is a full circle structure around the winding shaft body 2, and does not affect the structure and function of the seat clamping claw 32.

[0149] In another embodiment, the width of the intermediate groove 132 is greater than the distance between the upper edge and the lower edge of the seat stopper 34. That is, the distance between the abutting driving portion 11 and the cover stopper 131 is greater than the distance between the upper edge and the lower edge of the seat stopper 34. This structure can ensure that the seat stopper 34 is fully accommodated, and provide space for the relative movement of the cover body 1 and the seat body 3 when the retracting and extending action is switched, so as to facilitate the cooperation between the cover stopper 131 and the seat stopper 34 and ensure the smoothness and stability of the switching of the retracting and extending action.

[0150] The product form of the utility model is not limited to the illustrations and embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the utility model.
