Description

Technical Field

[0001] This application relates to the field of rope winding and unwinding devices, and more particularly to a finely adjustable rope winding and unwinding device and article. Background Technology

[0002] To make some household items suitable for different users, many household items are designed with drawstrings, such as sneakers, hats, sweatshirts, and gloves. The tightness of the item can be adjusted by tying a knot in the drawstring. However, in daily life, the knotted drawstring is sometimes easy to loosen and come undone. For example, shoelaces can easily become dirty or cause tripping. In particular, very young children cannot tie the drawstring themselves, and the elderly are also very inconvenient to bend over to tie the drawstring due to their physical weakness, which can easily lead to danger.

[0003] Therefore, a rope winding and unwinding device has appeared on the market, which is used to wind and unwind ropes. The rope can be tightened by rotating the knob. However, when releasing the rope, this type of rope winding and unwinding device can only release the entire rope at once. Otherwise, the rope will get stuck inside the product. Therefore, it is impossible to control the length of the rope when tightening and releasing, which makes it inconvenient to use when precise control of the rope is required.

[0004] While some other rope winding and unwinding devices can fine-tune the tightening and releasing of the rope, they cannot control the total length of the tightened and released rope, causing the rope to get stuck or squeezed inside the product, resulting in product malfunction and unusability.

[0005] Meanwhile, a small number of products control the total length of the rope using a single rope. However, their complex structure and difficult production and assembly result in low production efficiency, high product costs, and susceptibility to malfunctions such as rope jamming or breakage during operation. This leads to poor product stability and severely limits the use of such products. Summary of the Invention

[0006] Therefore, it is necessary to provide a finely adjustable rope winding and unwinding device that can control the total length of rope winding and unwinding, has a simpler structural design, and is easier to manufacture and assemble.

[0007] Firstly, the adjustable rope winding and unwinding device provided in this application includes...

[0008] The base includes a base plate and a first side plate disposed on one side of the base plate, the base plate and the first side plate forming a first receiving cavity; the first side plate has a ratchet portion at one end away from the base plate, the ratchet portion is arranged around the first side plate and located in the first receiving cavity; the first side plate has a first threading hole and a second threading hole for threading a rope, the second threading hole communicating with the first receiving cavity.

[0009] A winding wheel has a winding area for storing rope; the winding wheel is disposed in the first receiving cavity and is rotatably connected to the base.

[0010] A ratchet disc is disposed within the first receiving cavity and connected to the winding reel; the ratchet disc includes a ratchet arm, which can move along the ratchet tooth portion to control the length of the retrieved and released rope; when the ratchet arm abuts against the ratchet tooth portion, the ratchet disc and the winding reel are stationary relative to the base; when the ratchet arm disengages from the ratchet tooth portion, the ratchet disc and the winding reel can rotate relative to the base;

[0011] A knob is located on the side of the base facing the first receiving cavity and is rotatably connected to the base, and can rotate in a preset direction; the knob includes a top plate and a first driving member located on the top plate facing the base, the first driving member can drive the pawl arm to disengage from the ratchet portion and drive the winding wheel to rotate relative to the base, so as to store the rope in the winding area or release it from the winding area;

[0012] A control element is disposed between the winding wheel and the base. The winding wheel is rotatably connected to the base through the control element. When the knob is rotated in a preset direction, the control element can move between the base plate and the top plate in the direction from the base plate toward the top plate or from the top plate toward the base plate, so as to limit the rotation distance of the winding wheel and realize the control of the total length of the rope being stored or released.

[0013] Compared to existing technologies, the adjustable rope winding and unwinding device provided in this application drives the winding wheel to rotate relative to the base by rotating the knob, thereby enabling the rope to be stored in or released from the winding area. The pawl arm and ratchet portion, which abut against each other, limit the rotation distance of the winding wheel by the ratchet portion, thus precisely controlling the length of rope stored or released by the winding wheel. That is, each rotation of the knob allows the winding wheel to store or release a certain length of rope; continuous rotation of the knob... When the winding wheel is in operation, it can continuously take in or release the rope. Additionally, a control element is positioned between the winding wheel and the base, with the bottom plate and top plate limiting the total movement distance of the control element. This controls the total rotation distance of the winding wheel relative to the base, thereby controlling the total length of the rope during take-in or release. This prevents the rope from getting stuck or squeezed when it is wrapped around the winding area within the winding wheel, ensuring smooth product operation each time a certain distance of rope is taken in or released.

[0014] Furthermore, in some embodiments, the base plate has a fixing post on the side facing the first receiving cavity, and the fixing post has a flange; the control component has a first mounting hole and a limiting groove communicating with the first mounting hole, and when the first mounting hole is fitted onto the fixing post, the flange is located in the limiting groove; the control component also has an external thread, and the winding wheel includes a main body, and the main body has a second mounting hole with an internal thread, the second mounting hole being screwed to the control component; when the knob drives the winding wheel to rotate relative to the base, the winding wheel can drive the control component to move along the axial direction of the fixing post. The control component is connected to the fixed column via the limiting groove and the flange, thereby restricting the rotation of the control component around the fixed column. Simultaneously, since the control component is screwed to the winding wheel, when the winding wheel rotates around the fixed column, the control component can only move axially along the fixed column. When the control component moves to the top plate or the bottom plate and cannot move further, the winding wheel will also be unable to rotate around the fixed column, making it impossible to collect or release the rope. This achieves accurate control of the total length of the collected or released rope. Furthermore, the control component with this structure is simple in design and has high operational stability. The method for controlling the total length of the rope is simple, and the manufacturing process is also simple. In particular, it allows for rapid assembly, effectively reducing production costs and thus improving product competitiveness.

[0015] Furthermore, in some embodiments, the winding reel further includes a first substrate disposed on the main body and a second substrate spaced apart from the first substrate. The first substrate, the second substrate, and the main body form the winding area. The main body located in the winding area is provided with a third threading hole for fixing one end of the rope. The first threading hole fixes the other end of the rope, and the rope is received in the winding area or released from the winding area through the second threading hole. By setting the first substrate and the second substrate to form the winding area, the rope can be controlled in the receiving area of ​​the winding reel. At the same time, setting the third threading hole for fixing the rope in the winding area allows the rope to be directly received in the winding area when receiving it.

[0016] Further, in some embodiments, the second substrate is located on the main body portion between the first substrate and the base plate, and the third through hole penetrates the main body portion of the winding area and the first substrate; a second driving member is provided on the side of the first substrate away from the second substrate, the first driving member is located on one side of the second driving member and abuts against the first substrate, and the pawl arm is located on the side of the first driving member away from the second driving member and abuts against the first substrate; the preset direction includes a first direction and a second direction, when the knob is rotated along the first direction, the first driving member abuts against and drives the second driving member to drive the winding wheel to rotate around the fixed post to collect the rope; when the knob is rotated along the second direction, the first driving member abuts against and drives the pawl arm to drive the winding wheel to rotate in the opposite direction around the fixed post to release the rope; when the knob is stopped from being rotated, the pawl arm abuts against the ratchet portion to restrict the rotation of the winding wheel. The third threading hole passes through the winding area and the first substrate, so that the knot when fixing the rope can be set on the first substrate, effectively utilizing the space; the second driving member makes it more convenient and faster for the first driving member to drive the winding wheel, so that the winding wheel can be driven by turning the knob.

[0017] Furthermore, in some embodiments, a third driving member is provided on the side of the first substrate away from the second substrate. The third driving member is located on the side of the pawl arm away from the first driving member. When the knob is rotated in the second direction, the first driving member abuts against and drives the pawl arm, causing the pawl arm to disengage from the ratchet tooth and abut against and drive the third driving member to rotate the winding wheel in the opposite direction around the fixed post to release the rope. The provision of the third driving member allows the first driving member to indirectly drive the third driving member by driving the pawl arm when the knob is rotated in the second direction, thereby driving the winding wheel to rotate in the second direction to release the rope. This avoids damage to the pawl arm when rotating in the second direction, thus extending the product's service life.

[0018] Furthermore, in some embodiments, the ratchet disc further includes a third base plate with a mounting opening, an elastic arm connected to the third base plate, and a connecting portion with a positioning hole connected to the end of the elastic arm away from the third base plate. The third base plate is fitted onto the main body through the mounting opening, and the ratchet arm is connected to the end of the connecting portion away from the elastic arm. A positioning post is also provided on the side of the first base plate away from the second base plate. The positioning post is located between the second driving member and the third driving member, and the positioning hole is fitted onto the positioning post. The provision of the third base plate with the mounting opening and the positioning post not only ensures a stable connection between the ratchet disc and the winding wheel, but also allows the winding wheel and the ratchet disc to be driven so that the other can be rotated. At the same time, the elastic arm also allows the ratchet arm to have a certain degree of elasticity, enabling it to disengage from and abut against the ratchet tooth, thereby allowing the winding wheel to rotate or remain stationary relative to the base.

[0019] Furthermore, in some embodiments, the first substrate has a protrusion on the side away from the second substrate, the protrusion abutting against the pawl arm; the second drive member is arc-shaped, and its end away from the first drive member is connected to the main body, the positioning post being disposed in the arc-shaped area of ​​the second drive member. The protrusion reduces the contact area between the pawl arm and the first substrate during deformation, thereby reducing friction; placing the positioning post in the arc-shaped area of ​​the second drive member makes the pawl disc more stable, preventing it from shaking and affecting product stability.

[0020] Furthermore, in some embodiments, the knob further includes a first limiting portion disposed on the top plate near the bottom plate and a second side plate disposed along the periphery of the top plate. The top plate and the second side plate enclose a second receiving cavity. The first driving member and the first limiting portion are located within the second receiving cavity, and the first limiting portion abuts against the pawl arm. The second side plate has a second limiting portion on the side facing the second receiving cavity. The second limiting portion forms a locking groove with the second side plate and the top plate. The first side plate also has a locking portion protruding from the first side plate on the side away from the first receiving cavity. The locking portion engages with the locking groove, and the locking portion and the locking groove can slide relative to each other. The second limiting portion also has a slope on the side away from the top plate. The second side plate also has an anti-slip structure on the side away from the second receiving cavity. The first limiting part abuts against the pawl arm, which can prevent the pawl arm from wobbling up and down and improve the stability of the product during rotation; the snap-fit ​​groove is provided to snap into the base, and the inclined surface is provided to facilitate the installation of the product and also to enable relative rotation between the knob and the base; in addition, an anti-slip structure is provided to make it easier for users to rotate the knob and improve the user experience.

[0021] Furthermore, in some embodiments, the adjustable rope winding and unwinding device further includes a fixing member, which includes a limiting plate and a threaded portion disposed on one side of the limiting plate; the fixing post has a fixing hole, the threaded portion passes through the fixing hole, and the limiting plate abuts against the end of the fixing post away from the base plate; when the knob is rotated to drive the winding wheel to rotate relative to the base, the winding wheel can drive the control member to move between the limiting plate and the base plate along the axial direction of the fixing post. The fixing member is connected to the fixing post to restrict the axial movement of the winding wheel and the ratchet disc around the fixing post, ensuring that they can only rotate around the fixing post. Simultaneously, the fixing member can also restrict the control member to move only between the base plate and the fixing member, preventing the control member from affecting the top plate of the knob.

[0022] Furthermore, in some embodiments, the adjustable cord retraction device further includes a base located on the side of the base away from the knob and fixed to the base. By providing the base, the adjustable cord retraction device can be fixed to the item to be used, thereby making better use of the device.

[0023] Secondly, this application also provides a dual-sided adjustable rope winding and unwinding device, including the aforementioned adjustable rope winding and unwinding device, wherein there are two first threading holes and two second threading holes, symmetrically arranged on the first side plate, so that the dual-sided adjustable rope winding and unwinding device can simultaneously wind and unwind ropes on opposite sides. The symmetrical arrangement of two sets of first threading holes and second threading holes on the first side plate allows for the simultaneous threading of two ropes, thereby achieving simultaneous wind and unwinding of the ropes, so as to simultaneously tighten or loosen two items.

[0024] Thirdly, this application also provides an article having a first part, a second part, and a rope, the rope being used to tighten or release the first part and the second part. The article further includes the aforementioned adjustable rope retraction device, which is used to store and / or release the rope. The article can be one of the following: shoes, hats, gloves, medical protective gear, helmets, storage devices, ski protective gear, bags, or clothing, or other items that require tightening or loosening with a rope.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] Firstly, please refer to Figure 1 , Figure 1 This is a perspective view of the adjustable rope retraction device 1 shown in the embodiment of this application. The adjustable rope retraction device 1 provided in this application can be used for shoes, hats, gloves, helmets, medical protective gear, storage devices, ski protective gear, etc. With the help of ropes, such items can be tightened and loosened. It is simple and convenient to use, especially for the elderly, children, patients, or in special scenarios.

[0049] Please see Figure 2 and Figure 3 The adjustable rope winding device 1 in this embodiment includes a base 10, a winding wheel 20, a ratchet disc 30, a knob 40, and a control component 50.

[0050] Please see Figure 4 and Figure 5 The base 10 includes a base plate 11 and a first side plate 12 disposed on one side of the base plate 11. The base plate 11 and the first side plate 12 enclose each other to form a first receiving cavity 13. The first side plate 12 is provided with a ratchet portion 121 at one end away from the base plate 11. The ratchet portion 121 is arranged around the first side plate 12 and located in the first receiving cavity 13. The first side plate 12 is provided with a first threading hole 14 and a second threading hole 15 for threading a rope. The second threading hole 15 communicates with the first receiving cavity 13.

[0051] The winding reel 20 has a winding area 21 for receiving the rope; the winding reel 20 is disposed within the first receiving cavity 13 and rotatably connected to the base 10. A ratchet disc 30 is disposed within the first receiving cavity 13 and connected to the winding reel 20; the ratchet disc 30 includes a ratchet arm 31, which is movable along the ratchet tooth portion 121 to control the length of the received and released rope. When the ratchet arm 31 abuts against the ratchet tooth portion 121, the ratchet disc 30 and the winding reel 20 are stationary relative to the base 10; when the ratchet arm 31 disengages from the ratchet tooth portion 121, the ratchet disc 30 and the winding reel 20 can rotate relative to the base 10. A knob 40 is located on the side of the base 10 facing the first receiving cavity 13 and is rotatably connected to the base 10, allowing it to rotate in a preset direction. The knob 40 includes a top plate 41 and a first driving member 42 located on the side of the top plate 41 facing the base 10. The first driving member 42 can drive the pawl arm 31 to disengage from the ratchet portion 121 and drive the winding wheel 20 to rotate relative to the base 10, so as to store the rope in the winding area 21 or release it from the winding area 21. A control member 50 is located between the winding wheel 20 and the base 10, and the winding wheel 20 is rotatably connected to the base 10 through the control member 50. When the knob 40 is rotated in a preset direction, the control member 50 can move between the base plate 11 and the top plate 41 in a direction from the base plate 11 toward the top plate 41 or from the top plate 41 toward the base plate 11, so as to limit the rotation distance of the winding wheel 20 and realize the control of the total length of the rope stored or released.

[0052] Specifically, in this embodiment, the first threading hole 14 is used to fix one end of the rope, and the middle portion of the rope passes through the second threading hole 15 to fix the other end of the rope to the winding reel 20. The end of the rope fixed to the first threading hole 14 needs to be knotted or sintered to prevent the rope from detaching from the first threading hole 14. Therefore, in this embodiment, a cavity is also provided on one side of the first threading hole 14 to accommodate the knotted or sintered portion of the rope. Of course, in other embodiments, the first threading hole 14 can also be other structures capable of fixing one end of the rope, such as a fixing ring, a fixing hook, a post with a groove, or a nail, as long as it can fix one end of the rope.

[0053] Compared to existing technologies, the adjustable rope winding and unwinding device 1 provided in this application drives the winding wheel 20 to rotate relative to the base 10 by rotating the knob 40, thereby enabling the rope to be stored in or released from the winding area 21. The ratchet arm 31 and ratchet tooth 121, which abut against each other, limit the rotation distance of the winding wheel 20 by the ratchet tooth 121, thus precisely controlling the length of rope stored or released by the winding wheel 20. That is, each rotation of the knob 40 allows the winding wheel 20 to store or release a certain length of rope, and continuous rotation... When knob 40 is turned, the winding wheel 20 can continuously take in or release the rope. In addition, a control element 50 is set between the winding wheel 20 and the base 10. The total movement distance of the control element 50 is limited by the base plate 11 and the top plate 41, thereby controlling the total rotation distance of the winding wheel 20 relative to the base 10. This allows the total length of the rope to be controlled when taking in or releasing it, thus preventing the rope from getting stuck or squeezed when it is wrapped in the winding area 21 inside the winding wheel 20. This ensures that the product can operate smoothly each time a certain distance of rope is taken in or released.

[0054] Continue reading Figures 2-5A fixing post 16 is provided on the side of the base plate 11 facing the first receiving cavity 13. A flange 161 is provided on the fixing post 16. Specifically, the flange 161 is a protruding strip protruding from the fixing post 16, and the protruding strip extends axially along the outer periphery of the fixing post 16. In this embodiment, the control component 50 is a threaded sleeve. The control component 50 is provided with a first mounting hole 51 and a limiting groove 52 communicating with the first mounting hole 51. When the first mounting hole 51 is fitted onto the fixing post 16, the flange 161 is located in the limiting groove 52. The control component 50 is also provided with an external thread. The winding wheel 20 includes a main body 22, and the main body 22 is provided with a second mounting hole 221 with an internal thread. The second mounting hole 221 is screwed to the control component 50. When the knob 40 drives the winding wheel 20 to rotate relative to the base 10, the winding wheel 20 can drive the control component 50 to move along the axial direction of the fixing post 16. The control component 50 is connected to the fixed column 16 via a limiting groove 52 and a flange 161, thereby restricting the rotation of the control component 50 around the fixed column 16. Simultaneously, since the control component 50 is screwed to the winding wheel 20, when the winding wheel 20 rotates around the fixed column 16, the control component 50 can only move axially along the fixed column 16. When the control component 50 moves to the top plate 41 or bottom plate 11 and cannot move further, the winding wheel 20 will also be unable to rotate around the fixed column 16, making it impossible to collect or release the rope. This achieves accurate control of the total length of the collected or released rope. Furthermore, the control component 50 with this structure is simple in design and has high operational stability. The method for controlling the total length of the rope is simple, and the manufacturing process is also simple. In particular, it allows for rapid assembly, effectively reducing production costs and thus improving product competitiveness.

[0055] For ease of understanding, the adjustable rope winding and unwinding device 1 provided in this embodiment has preset directions including a first direction and a second direction. Specifically, the first direction and the second direction are two opposite directions. Taking the direction of the knob 40 as a reference, in this embodiment, the first direction is set to clockwise and the second direction to counterclockwise. When the knob 40 is rotated clockwise, the winding wheel 20 winds the rope into the winding area 21; when the knob 40 is rotated counterclockwise, the winding wheel 20 releases the rope. During this process, the control member 50 moves between the base plate 11 and the top plate 41 along the axial direction of the fixed column 16. Taking the moment when the control member 50 abuts against the base plate 11 as an example, the rope is released and not winded back into the winding wheel 20. Please refer to [link to relevant documentation]. Figure 6 , Figure 6 yes Figure 1 The diagram shows a cross-sectional view of the adjustable cord retraction device 1 in its retracted position. When the knob 40 is turned clockwise until the cord is fully retracted into the winding reel 20, the control element 50 reaches the end of the fixed post 16 furthest from the base plate 11. To release the cord, the knob 40 is turned counterclockwise, releasing the cord. Continue turning the knob 40 counterclockwise until the cord is fully released. (See attached diagram). Figure 7 , Figure 7 yes Figure 1 The diagram shows a cross-sectional view of the adjustable rope winding and unwinding device 1 in the release state. At this time, the control element 50 abuts against the base plate 11, and the rope is completely released. The adjustable rope winding and unwinding device 1 in this embodiment is equipped with a control element 50. Based on the distance the winding wheel 20 rotates when the control element 50 moves axially along the fixed column 16, the total length that the winding wheel 20 can accommodate when the rope is fully wound or released can be determined. Therefore, the total length of rope that the winding area 21 can accommodate is greater than or equal to the total length of rope that can be wound or released. This ensures that the rope is under control whether it is being wound into or released from the winding wheel 20 during product use. This prevents the rope from getting stuck or squeezed on the winding wheel 20 inside the product when it is precisely tightened or released, thereby reducing the product failure rate and ensuring product quality.

[0056] Please see Figure 8 and Figure 9 The winding reel 20 also includes a first substrate 23 disposed on the main body 22 and a second substrate 24 spaced apart from the first substrate 23. The first substrate 23, the second substrate 24, and the main body 22 form a winding area 21. A third threading hole 222 for fixing one end of the rope is provided on the main body 22 located in the winding area 21. The first threading hole 222 fixes the other end of the rope, and the rope is stored in or released from the winding area 21 through the second threading hole 222. It is understood that the third threading hole 222 can also be other structures for fixing one end of the rope. This application uses a hole as an example. By setting the first substrate 23 and the second substrate 24 to form the winding area 21, the rope can be controlled in the storage area of ​​the winding reel 20. At the same time, by setting the third threading hole 222 for fixing the rope in the winding area 21, the rope can be directly stored in the winding area 21 when it is stored.

[0057] Specifically, the second substrate 24 is located on the main body 22 between the first substrate 23 and the base plate 11. The third wire-passing hole 222 penetrates the main body 22 of the winding area 21 and the first substrate 23. In this embodiment, the third wire-passing hole 222 penetrates the main body 22 of the winding area 21 and the first substrate 23 to facilitate the installation of the rope on the winding wheel 20. At the same time, a cavity is provided on the side of the first substrate 23 away from the second substrate 24 to facilitate the accommodation of the rope end in the knotted or sintered part, and to make full use of the internal space of the product. A second driving member 25 is provided on the side of the first substrate 23 away from the second substrate 24. The first driving member 42 is located on the side of the second driving member 25 and abuts against the first substrate 23. The pawl arm 31 is located on the side of the first driving member 42 away from the second driving member 25 and abuts against the first substrate 23.

[0058] Please see Figure 10 , Figure 10The diagram shows the rope being released from the product; please refer to it as well. Figure 11 and Figure 12 When the knob 40 is rotated in the first direction, the first driving member 42 abuts against and drives the second driving member 25 to rotate the winding wheel 20 around the fixed post 16 to collect the rope. When the knob 40 is rotated in the second direction, the first driving member 42 abuts against and drives the pawl arm 31 to rotate the winding wheel 20 in the opposite direction around the fixed post 16 to release the rope. When the knob 40 is stopped, the pawl arm 31 abuts against the ratchet part 121 to restrict the rotation of the winding wheel 20. The third threading hole 222 passes through the winding area 21 and the first base plate 23, so that the knotting part when fixing the rope can be set on the first base plate 23, effectively utilizing the space. The second driving member 25 makes it more convenient and faster for the first driving member 42 to drive the winding wheel 20, so that the winding wheel 20 can be driven by rotating the knob 40.

[0059] To enable the knob 40 to better drive the winding wheel 20, a third driving member 26 is provided on the side of the first base plate 23 away from the second base plate 24. The third driving member 26 is located on the side of the pawl arm 31 away from the first driving member 42. When the knob 40 is rotated in the second direction, the first driving member 42 abuts against and drives the pawl arm 31. The pawl arm 31 disengages from the ratchet tooth 121 and abuts against and drives the third driving member 26, causing the winding wheel 20 to rotate in the opposite direction around the fixed post 16 to release the rope. The third driving member 26 allows the first driving member 42 to indirectly drive the third driving member 26 by driving the pawl arm 31 when the knob 40 is rotated in the second direction, thereby driving the winding wheel 20 to rotate in the second direction to release the rope. This avoids damage to the pawl arm 31 when rotating in the second direction, thus extending the product's service life.

[0060] Please see Figure 13 The pawl disc 30 also includes a third base plate 32 with a mounting opening 321, an elastic arm 33 connected to the third base plate 32, and a connecting portion 35 with a positioning hole 34 connected to the end of the elastic arm 33 away from the third base plate 32. The third base plate 32 is sleeved on the main body 22 through the mounting opening 321, and the pawl arm 31 is connected to the end of the connecting portion 35 away from the elastic arm 33. A positioning post 27 is also provided on the side of the first base plate 23 away from the second base plate 24. The positioning post 27 is located between the second drive member 25 and the third drive member 26, and the positioning hole 34 is sleeved on the positioning post 27. The third base plate 32 with the mounting opening 321 and the positioning post 27 not only make the pawl disc 30 and the winding wheel 20 firmly connected, but also allow the other to rotate when one of the winding wheel 20 and the pawl disc 30 is driven. At the same time, the elastic arm 33 also allows the pawl arm 31 to have a certain elasticity, so that it can disengage from and abut against the ratchet portion 121, thereby enabling the winding wheel 20 to rotate or remain stationary relative to the base 10.

[0061] Specifically, the first substrate 23 has a protrusion 231 on the side away from the second substrate 24, which abuts against the pawl arm 31; the second drive member 25 is arc-shaped, and its end away from the first drive member 42 is connected to the main body 22, with the positioning post 27 located in the arc-shaped area of ​​the second drive member 25. The protrusion 231 reduces the contact area between the pawl arm 31 and the first substrate 23 during deformation, thereby reducing friction; the positioning post 27 is located in the arc-shaped area of ​​the second drive member 25, making the pawl disc 30 more stable and preventing it from shaking and affecting the stability of the product.

[0062] Please see Figure 14 The knob 40 also includes a first limiting part 411 located on the top plate 41 near the bottom plate 11, and a second side plate 43 located along the periphery of the top plate 41. The top plate 41 and the second side plate 43 together form a second receiving cavity 44. The first driving member 42 and the first limiting part 411 are located within the second receiving cavity 44, and the first limiting part 411 abuts against the pawl arm 31. The second side plate 43 has a second limiting part 45 on the side facing the second receiving cavity 44. The second limiting part 45 and the second... The side plate 43 and the top plate 41 form a snap-fit ​​groove 46. The side of the first side plate 12 away from the first receiving cavity 13 is also provided with a snap-fit ​​part 122 protruding from the first side plate 12. The snap-fit ​​part 122 engages with the snap-fit ​​groove 46, and the snap-fit ​​part 122 and the snap-fit ​​groove 46 can slide relative to each other. The side of the second limiting part 45 away from the top plate 41 is also provided with a slope. The side of the second side plate 43 away from the second receiving cavity 44 is also provided with an anti-slip structure 47. Specifically, the anti-slip structure 47 is an anti-slip texture. Of course, an indicator arrow can also be provided on the side of the top plate 41 away from the bottom plate 11 to indicate the direction of turning the knob 40 when storing the product cord. The first limiting part 411 abuts against the pawl arm 31, which can prevent the pawl arm 31 from wobbling up and down and improve the stability of the product during rotation; the snap-fit ​​groove 46 is set to snap into the base 10, and the inclined surface is set to facilitate the installation of the product, and at the same time, it can realize the relative rotation between the knob 40 and the base 10; in addition, an anti-slip structure is set to make it easy for users to rotate the knob 40 and improve the user experience.

[0063] Continue reading Figure 2 and Figure 3In this embodiment, the adjustable rope winding and unwinding device 1 further includes a fixing member 60, which includes a limiting plate 61 and a threaded portion 62 located on one side of the limiting plate 61. A fixing hole 162 is provided on the fixing post 16, and the threaded portion 62 passes through the fixing hole 162. The limiting plate 61 abuts against the end of the fixing post 16 away from the base plate 11. When the knob 40 is rotated to drive the winding wheel 20 to rotate relative to the base 10, the winding wheel 20 can drive the control member 50 to move between the limiting plate 61 and the base plate 11 along the axial direction of the fixing post 16. The fixing member 60 is connected to the fixing post 16 to restrict the axial movement of the winding wheel 20 and the ratchet disc 30 around the fixing post 16, ensuring that they can only rotate around the fixing post 16. Simultaneously, the fixing member 60 can also restrict the control member 50 to move only between the base plate 11 and the fixing member 60, preventing the control member 50 from affecting the top plate 41 of the knob 40.

[0064] Specifically, the adjustable cord winding device 1 also includes a base 70, which is located on the side of the base 10 away from the knob 40 and fixed to the base 10.
