The first axial limiting portion can be snapped together with the bottom of the storage seat, and on the basis of ensuring that the rope winding shaft has the function of rotating relative to the storage seat, 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 unit drives the winding shaft body by using the 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 second axial limiting portion of the rope winding shaft through the third axial limiting portion, and limits the relative axial position of the cover body and the rope winding shaft. The rope storage state can also be switched by snapping the third axial limiting portion with the second axial limiting portion at different axial positions. Compared with the prior art, the new rope storage device of the utility model has the advantages of simple structure and high strength, easy demoulding, simple processing and assembly procedures, low cost, simple assembly, small rotation contact surface, stable working performance, smooth and efficient operation, and reasonable and practical structure.

[0099] In another embodiment, the second sliding portion includes a smooth convex curved surface. This structure ensures that the second sliding portion facilitates the second protrusion 1612 to slide smoothly relative to the edge of the protrusion in the hole.

[0100] In another embodiment, the second sliding portion includes a smooth inclined surface that protrudes outward. This structure ensures that the second sliding portion facilitates the second protrusion 1612 to slide smoothly relative to the edge of the protrusion in the hole.

[0101] In another embodiment, the third axial limit portion 161 includes a second axial depression that matches the protrusion in the hole. The second protrusion 1612 is connected to the protrusion in the hole by a rotatable snap fit through the second axial depression, which can prevent the rope winding shaft from escaping from the storage seat, especially prevent the wound rope from supporting the rope winding shaft and escaping from the storage seat. It can also realize the smooth insertion of the cover shaft 16 into the second axial limit portion 261 for positioning, or realize the smooth insertion and removal of the cover shaft 16 to switch between different storage states of the rope.

[0102] In another embodiment, the third axial limiting portion 161 includes a first anti-slipping head 1615. The first anti-slipping head 1615 can realize the positioning and anti-slipping of the cover body 1 and the rope winding shaft, especially to prevent the cover body 1 from being completely separated from the rope winding shaft when the rope is loosened and the cover body 1 is pulled out. 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] In another embodiment, the seat body is provided with a fifth axial limiter that matches with the rope winding shaft. The fifth axial limiter matches with at least one of the rope winding shaft and the cover shaft 16 to limit the rope winding shaft in the axial direction of the rope winding shaft, ensuring that the rope winding shaft is accurately positioned and moves smoothly and stably.

[0108] In another embodiment, the fifth axial limiting portion includes a clamping edge, a clamping hole or a clamping slot that is matched with the first axial limiting portion. This clamping edge, clamping hole or clamping slot can be matched with the first axial limiting portion to prevent the rope winding axis from moving toward the bottom direction away from the rope storage seat, thereby achieving the dual effects of relative rotation and clamping.

[0109] In another embodiment, the fifth axial limiting portion includes a recessed groove for accommodating the lower end of the rope winding shaft. The recessed groove can accommodate the lower end of the rope winding shaft to prevent the rope from moving and has a coaxial limiting effect on the rope winding shaft.

[0110] In another embodiment, the sink is cylindrical. This structure is conducive to the smooth rotation of the rope winding shaft.

[0111] In another embodiment, the fifth axial limiting portion includes a seat convex portion extending into the concave hole at the lower end of the rope winding shaft. The seat convex portion can limit the lower end of the rope winding shaft to prevent the rope from moving and has a coaxial limiting effect on the rope winding shaft.

[0112] In another embodiment, the seat protrusion is cylindrical. This structure is conducive to the smooth rotation of the rope winding shaft.

[0113] In another embodiment, a hole or a groove is formed in the middle of the seat protrusion. This structure is convenient for matching with the cover shaft 16.

[0114] In another embodiment, the shaft side teeth 21 are located at the upper part of the winding shaft body 2. This structure facilitates the shaft side teeth 21 to correspond to and cooperate with the seat claws 32 at the upper part of the seat side wall 31.

[0115] In another embodiment, the shaft side teeth 21 are located at the upper edge of the winding shaft body 2. This structure facilitates the shaft side teeth 21 to correspond with the seat claws 32 on the upper part of the seat side wall 31, does not affect the rope winding inside, and can avoid the shaft 22 for easy molding.

[0116] In another embodiment, the winding shaft body 2 includes a shaft portion 22 and an upper shaft end wall 23 provided at the upper end of the shaft portion 22. The shaft portion 22 is used to wind the rope, and a threading hole may be provided on the shaft portion 22. The upper shaft end wall 23 may limit the wound rope and carry the shaft side teeth 21 and the like.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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 cover body 1 and the seat body 3 to move relative to each other 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.
