[0006] Optionally, the outgoing end of the auxiliary rope is bonded or welded to the main rope, and the outgoing end of the auxiliary rope is positioned close to the lock head; and / or, The fixed end of the auxiliary rope is provided with an installation part, which is adapted to cooperate with the mating part on the second winding reel to fix the fixed end of the auxiliary rope to the winding periphery of the second winding reel.

[0007] Optionally, it also includes a telescopic rope loop, which is fitted over the exit end of the main rope and covers the exit end of the auxiliary rope therein. One end of the telescopic rope loop is adapted to be fixed at the rope outlet of the traction device body, and the other end is connected and fixed to the exit end of the main rope, so that the lock head can be exposed from the telescopic rope loop.

[0008] Optionally, the width of the main rope is greater than the width of the auxiliary rope; and / or, The main rope is made of flexible rope material, and the auxiliary rope is made of metal material.

[0009] This utility model also provides a winding assembly, including: The first winding disk and the second winding disk are rotatably disposed on the same rotation plane, and the orthographic projections of the winding area of ​​the first winding disk and the winding area of ​​the second winding disk in a direction parallel to the rotation plane at least partially overlap. The aforementioned traction rope has its main rope wound around the first winding reel, and its auxiliary rope wound around the second winding reel. The first winding reel has a wire-locking groove at its winding center, and the fixed end of the main rope is housed in the wire-locking groove. The second winding reel has a mating part on its periphery, and the fixed end of the auxiliary rope has an installation part that mates with the mating part.

[0010] Optionally, the second winding reel has a winding groove on its periphery, and the mating part includes a wire-clamping post extending along the winding axis of the first winding reel. The wire-clamping post is clamped onto the two side walls of the winding groove, and the two side walls of the winding groove are arranged opposite to each other along the winding axis of the first winding reel. The mounting part includes a retaining ring at the fixed end of the auxiliary rope. The retaining ring is sleeved on the outside of the wire-clamping post, so that the auxiliary rope can be wound around the winding groove.

[0011] Optionally, at least one of the first winding reel and the second winding reel is provided with an elastic element, which allows the portion of the main rope wound from the first winding reel and the portion of the auxiliary rope wound from the second winding reel to remain in a taut state.

[0012] Optionally, the elastic element is configured as a coil spring. When the auxiliary rope is subjected to an external force and unwinds from the second winding reel, the coil spring is in a tightened state; when the external force on the auxiliary rope is removed, the coil spring is in a released state, allowing the auxiliary rope to automatically wind back onto the second winding reel.

[0013] This utility model also provides a pet leash device, including the aforementioned winding assembly.

[0014] The technical solution provided by this utility model has the following beneficial effects: The leash provided by this utility model includes a main rope and an auxiliary rope.

Furthermore, the outgoing end of the auxiliary rope is attached to the main rope, and the fixed end of the auxiliary rope is adapted to be installed on a second winding reel, and the auxiliary rope is wound in and out of the second winding reel to achieve the winding and unwinding of the auxiliary rope. Moreover, the stiffness of the auxiliary rope is greater than that of the main rope. The auxiliary rope provides support to the main rope, ensuring a certain tension when the main rope winds out. This prevents the traction rope from twisting and tangling, making the winding and unwinding of the traction rope smoother. Furthermore, when winding out the traction rope, the auxiliary rope can be wound out from the second winding reel simply by driving it. Since the auxiliary rope is closely connected to the main rope, its pushing force can move the main rope along with it, allowing it to also wind out from the first winding reel. This eliminates the need to drive the first winding reel, saving energy, simplifying the structure, and reducing costs. Attached Figure Description

[0022] This utility model provides a leash 100, suitable for installation on a pet leash device to control a pet. For details, please refer to [link / reference needed]. Figures 1 to 2 In this embodiment, the traction rope 100 includes a main rope 1 and an auxiliary rope 2. Both the main rope 1 and the auxiliary rope 2 have a winding end and a fixed end arranged opposite to each other. The winding end of the main rope 1 is provided with a lock head 11, and the fixed end of the main rope 1 is adapted to be installed on the first winding reel 4. The winding end of the auxiliary rope 2 is attached to the main rope 1 and provides support for the main rope 1, so that the main rope 1 can be wound out in a tensioned state. The fixed end of the auxiliary rope 2 is adapted to be installed on the second winding reel 5. The stiffness of the auxiliary rope 2 is greater than that of the main rope 1.

[0023] In this embodiment, the locking head 11 is adapted to be quickly locked onto a pet's collar or clothing cover to connect with the pet. The fixed end of the main rope 1 is adapted to be installed on the first winding reel 4. The main rope 1 is wound in and out of the first winding reel 4 to achieve the winding and unwinding of the main rope 1. Moreover, the unwinding end of the auxiliary rope 2 is attached to the main rope 1, and the fixed end of the auxiliary rope 2 is adapted to be installed on the second winding reel 5. The auxiliary rope 2 is wound in and out of the second winding reel 5 to achieve the winding and unwinding of the auxiliary rope 2. Furthermore, since the stiffness of the auxiliary rope 2 is greater than that of the main rope 1, the auxiliary rope 2 can control the main rope 1. This provides support, ensuring the main rope 1 has a certain tension when winding out, preventing the traction rope 100 from twisting and tangling, and making the winding and unwinding of the traction rope 100 smoother. Furthermore, when winding out the traction rope 100, the auxiliary rope 2 can be wound out from the second winding reel 5 by simply driving the second winding reel 5. Since the auxiliary rope 2 is closely connected to the main rope 1, the pushing force of the auxiliary rope 2 can drive the main rope 1 to move together, allowing the main rope 1 to also wind out from the first winding reel 4. This eliminates the need to drive the first winding reel 4, saving energy, simplifying the structure, and reducing costs.

[0024] The main rope 1 is made of a flexible rope material, such as nylon or cotton. The auxiliary rope 2 is made of a metal material, such as a metal sheet or wire. Furthermore, the width of the main rope 1 is greater than the width of the auxiliary rope 2, allowing the auxiliary rope 2 to provide a certain degree of rigid support to the main rope 1 without being excessively stiff. This ensures that the traction rope 100 does not become tangled unnecessarily, while also maintaining flexibility, allowing the pet greater freedom of movement.

[0025] Moreover, combined Figure 2As shown, both the main rope 1 and the auxiliary rope 2 are elongated strips, with the outgoing end and the fixed end corresponding to the two ends of the main rope 1 and the auxiliary rope 2 along their length, respectively. The outgoing end is the end closer to the pet, and the fixed end is the end fixed to the first winding reel 4 or the second winding reel 5. The main rope 1 is flat, and the outgoing end of the auxiliary rope 2 is bonded or welded to the main rope 1, with the outgoing end of the auxiliary rope 2 positioned close to the lock head 11. Preferably, along the width direction of the main rope 1, the auxiliary rope 2 is located in the middle of the main rope 1 to provide stable support for the main rope 1.

[0026] The lock head 11 includes a buckle protruding from the outward end of the main rope 1. The buckle is U-shaped and fixedly connected to the main rope 1, and is used to engage with a collar or clothing cover on the pet. Preferably, the buckle is made of metal for better strength and to allow for some movement with the locking device on the pet, thus facilitating the pet's free movement.

[0027] A locking post 12 is provided at the fixed end of the main rope 1. The locking post 12 is adapted to be sleeved on the winding center of the first winding reel 4, allowing the main rope 1 to pass through the periphery of the winding center of the first winding reel 4 and be wound around the outer periphery of the first winding reel 4. The locking post 12 is generally cylindrical, and the axial length of the locking post 12 is the same as the width of the main rope 1, so that the fixed end of the main rope 1 is fixed on the locking post 12. By locking the locking post 12 on the winding center of the first winding reel 4, when the first winding reel 4 rotates, the portion of the main rope 1 extending from the winding center can be wound around the outer periphery of the first winding reel 4 or unwound from the outer periphery of the first winding reel 4, thereby realizing the winding and unwinding of the main rope 1. The structure of the main rope 1 is simpler, and the assembly operation with the first winding reel 4 is also more convenient.

[0028] like Figure 2 As shown, a mounting part 21 is provided at the fixed end of the auxiliary rope 2. The mounting part 21 is adapted to cooperate with the mating part 51 on the second winding reel 5 to fix the fixed end of the auxiliary rope 2 to the circumference of the winding of the second winding reel 5. Since the width of the auxiliary rope 2 is small, if the same fixing method as the main rope 1 is used, the width of the second winding reel 5 will be small, which is not conducive to winding. By fixing the fixed end of the auxiliary rope 2 through the mating part 51 on the second winding reel 5, the winding of the auxiliary rope 2 becomes more convenient.

[0029] In addition, such as Figure 1As shown, the traction rope 100 also includes a telescopic rope sleeve 3. The telescopic rope sleeve 3 is fitted over the exit end of the main rope 1 and covers the exit end of the auxiliary rope 2. One end of the telescopic rope sleeve 3 is adapted to be fixed at the rope outlet of the traction device body, and the other end is connected and fixed to the exit end of the main rope 1, allowing the locking head 11 to be exposed from the telescopic rope sleeve 3. The telescopic rope sleeve 3 can protect the main rope 1 and the auxiliary rope 2, improve the strength of the traction rope 100, and also make the appearance of the traction rope 100 more aesthetically pleasing.

[0030] The telescopic rope sleeve 3 is made of a flexible material. One end of the telescopic rope sleeve 3, connected to the main body of the traction device, is open, and an edge extends outward from this opening. This edge is made of a rigid material to be fitted and fixed into a groove at the rope outlet of the main body of the traction device, thereby fixing one end of the telescopic rope sleeve 3 relative to the main body of the traction device. This prevents the main rope 1 and the auxiliary rope 2 from being completely pulled out when both are at their maximum extension. The telescopic rope sleeve 3 provides greater tensile strength support, better protecting the main rope 1 and the auxiliary rope 2.

[0031] This utility model also provides a winding assembly 1000, combined with... Figure 3 and Figure 4 As shown, the winding assembly 1000 includes a first winding reel 4, a second winding reel 5, and the aforementioned traction rope 100.

[0032] The first winding reel 4 and the second winding reel 5 are rotatably mounted on the same plane of rotation. This plane of rotation can refer to the ground, a support platform, a frame, or a portion of the traction device body. The orthographic projections of the winding areas of the first winding reel 4 and the second winding reel 5 in a direction parallel to the plane of rotation at least partially overlap. That is, the first winding reel 4 and the second winding reel 5 are arranged opposite each other along the radial directions of the first winding reel 4 and the second winding reel 5, thereby allowing the auxiliary rope 2 and the main rope 1 to be better overlapped after winding, enabling the auxiliary rope 2 to support the main rope 1.

[0033] The main rope 1 of the traction rope 100 is wound on the first winding reel 4, and the auxiliary rope 2 of the traction rope 100 is wound on the second winding reel 5.

[0034] The first winding reel 4 has a wire-locking groove 41 at its winding center, and the fixed end of the main rope 1 is housed in the wire-locking groove 41. The second winding reel 5 has a mating part 51 on its periphery, and the fixed end of the auxiliary rope 2 has an installation part 21 that mates with the mating part 51.

[0035] In this embodiment, the main rope 1 can be unwound and wound up via the first winding reel 4, and the auxiliary rope 2 can be unwound and wound up via the second winding reel 5, making it easier to wind in and out of the main rope 1 and the auxiliary rope 2. Furthermore, the fixed end of the main rope 1 can be limited and fixed via the cable clamping groove 41 to ensure that the main rope 1 does not completely come off when winding out, thus improving the winding effect when winding up. Moreover, the mounting part 21 and the mating part 51 cooperate to fix the fixed end of the auxiliary rope 2 to the outer periphery of the second winding reel 5, thereby better realizing the unwinding and winding of the auxiliary rope 2 when the second winding reel 5 rotates. Furthermore, since the auxiliary rope 2 can provide some support to the main rope 1, the main rope 1 has a certain tension when winding out, and the traction rope 100 does not easily twist and entangle, thus making the entire winding assembly 1000 smoother in use.

[0036] Among them, combined Figures 4 to 6 As shown, the first winding reel 4 is generally disc-shaped, with a protruding post protruding from the center of the first winding reel 4. The protruding post is hollow with an open top to form the cable clamping groove 41. A notch is provided on one side of the protruding post in the circumferential direction. The notch is used for the main rope 1 to be clamped in it, so that after winding out, it can be wound towards the outer circumferential side of the protruding post, so that it can be accommodated in the cable clamping groove 41 by the locking post 12 on the main rope 1 and is not easily dislodged from the cable clamping groove 41 in the winding direction.

[0037] Combination Figure 3 and Figure 4 As shown, the winding assembly 1000 further includes a first pressure plate 71, which covers the protruding post and is configured to close the top opening of the protruding post, so that the locking post 12 is not easily dislodged from the top opening of the wire-locking groove 41. The first pressure plate 71 can be connected to the rotational plane where the first winding disc 4 is located. For example, when the first pressure plate 71 is rotatably mounted on the bracket 200, the first pressure plate 71 can be connected to the bracket 200 by screws, studs, or pins. Furthermore, when the first pressure plate 71 is connected to the rotational plane, the first winding disc 4 can still rotate relative to the rotational plane.

[0038] The second winding reel 5 is also roughly annular in shape. A winding groove is provided on the outer periphery of the second winding reel 5, forming a complete ring with the groove opening radially outward. Furthermore, a guide wheel is provided on one radial side of the second winding reel 5, spaced apart from the opening of the winding groove. The exit end of the main rope 1 passes through this gap, creating an interference fit between the second winding reel 5 and the main rope 1. When the second winding reel 5 rotates towards the exit direction of the auxiliary rope 2, the friction between the second winding reel 5 and the main rope 1 drives the main rope 1 to move in the exit direction. When the second winding reel 5 rotates towards the entry direction of the auxiliary rope 2, the friction between the second winding reel 5 and the main rope 1 drives the main rope 1 to move in the entry direction. The rotation of the second winding reel 5 enables the winding of both ropes.

[0039] like Figure 5 As shown, the mating part 51 includes a wire-clamping post 511 extending along the winding axis of the second winding reel 5. The wire-clamping post 511 is clamped onto the two sidewalls of the winding groove, which are arranged opposite to each other along the winding axis of the second winding reel 5. The two ends of the wire-clamping post 511 pass through the two sidewalls of the winding groove. The mounting part 21 includes a retaining ring 211 located at the fixed end of the auxiliary rope 2. The retaining ring 211 is sleeved on the outside of the wire-clamping post 511, allowing the auxiliary rope 2 to be wound around the winding groove. The structure is simple and ensures that the auxiliary rope 2 is not easily dislodged from the second winding reel 5.

[0040] In one embodiment, the winding assembly 1000 may further include a first driver and a second driver. The first driver is used to drive the first winding reel 4 to rotate, and the second driver is used to drive the second winding reel 5 to rotate, so as to realize the automatic winding in and out of the main rope 1 and the auxiliary rope 2, and to better control the extension length of the traction rope 100, thereby better controlling the distance between the user and the pet.

[0041] In one embodiment, at least one of the first winding reel 4 and the second winding reel 5 is provided with an elastic element. The elastic element can keep the portion of the main rope 1 that winds out from the first winding reel 4 and the portion of the auxiliary rope 2 that winds out from the second winding reel 5 in a taut state, so as to prevent the leash 100 from scattering and getting tangled or knotted, and can also make the leash 100 exert a certain pulling force on the pet.

[0042] Preferably, combined with Figures 4 to 6As shown, the elastic element is a coil spring 6. When the auxiliary rope 2 is subjected to external force and unwinds from the second winding reel 5, the coil spring 6 is in a tightened state; when the external force on the auxiliary rope 2 is removed, the coil spring 6 is in a released state, allowing the auxiliary rope 2 to automatically wind back onto the second winding reel 5. This ensures that the traction rope 100 remains taut during unwinding and rewinding, resulting in better traction. For example, when the traction rope 100 is connected to a pet, the pet can provide the power for the traction rope 100 to unwind. When the pet moves close to the winding assembly 1000, the unwinding traction rope 100 will be in a slack state. At this time, under the stress of the coil spring 6, the first winding reel 4 and / or the second winding reel 5 can be driven to contract and rotate, thereby tightening the traction rope 100.

[0043] Preferably, the coil spring 6 is disposed on the second winding reel 5, and two protrusions protrude from the center of the second winding reel 5, the two protrusions being arranged relatively at intervals. The coil spring 6 is a spiral coil spring, having a central end and a free end that winds outward from the central end circumferentially, the central end of the coil spring 6 being engaged between the intervals of the two protrusions. The winding assembly 1000 also includes a cover plate 72, the cover plate 72 being disposed on the second winding reel 5, and a clamping groove being provided on the side of the cover plate 72 facing the second winding reel 5, the clamping groove being located on the inner ring side of the second winding reel 5 and close to the inner ring wall of the second winding reel 5, the free end of the coil spring 6 being engaged in the clamping groove.

[0044] The winding assembly 1000 further includes a second pressure plate 73, which is adapted to be fixed to the rotating plane and forms an anti-rotation fit with the cover plate 72, so that when the second winding reel 5 rotates relative to the rotating plane, the cover plate 72 remains stationary, thereby allowing a torsional action on the coil spring 6. Specifically, when the auxiliary rope 2 winds outward, the free end of the coil spring 6 contracts in the direction of gradually tightening, causing the coil spring 6 to generate a winding stress; when the auxiliary rope 2 is no longer pulled by the pet or when the tension on the auxiliary rope 2 is less than the winding stress of the coil spring 6, the winding stress of the coil spring 6 can drive the second winding reel 5 to rotate in the opposite direction, so that the auxiliary rope 2 is wound onto the second winding reel 5, thereby ensuring that the traction rope 100 remains taut.

[0045] Preferably, a locking protrusion is provided on the side of the cover plate 72 facing away from the second winding reel 5, and a locking groove is provided on the second pressure plate 73. The locking protrusion is locked in the locking groove, and the cross-section of the locking protrusion is non-circular, so that the cover plate 72 will not rotate relative to the second pressure plate 73, so that when the second winding reel 5 rotates, the cover plate 72 is in a stationary state, and the coil spring 6 provides the power for the automatic winding of the auxiliary rope 2.

[0046] Furthermore, the second winding disc 5 and the bracket 200 can be connected by a first bearing 52, and the second winding disc 5 and the cover plate 72 can be connected by a second bearing 53, making the second winding disc 5 rotate more smoothly and with less effort.

[0047] This utility model also provides a pet leash device, including the aforementioned winding assembly 1000, which improves the leash effect for pets.

[0048] Furthermore, the pet-walking leash may also include a controller, and detection devices 8, such as position sensors and / or force sensors, may be installed on the main rope 1 and / or the auxiliary rope 2. The controller is electrically connected to the detection devices 8 and to the first and second actuators. When the position sensor detects that the main rope 1 and / or the auxiliary rope 2 are at their unwinding limit, the controller can control the first and second actuators to rotate in opposite directions according to the detection structure of the position sensor to wind up the main rope 1 and the auxiliary rope 2, preventing the leash 100 from being completely pulled out and damaged. And / or, when the force sensor detects that the tensile force on the main rope 1 and / or the auxiliary rope 2 is too large or too small, the controller can control the rotation direction of the first and second actuators according to the detection structure of the force sensor to wind up or unwind the main rope 1 and the auxiliary rope 2, preventing the leash 100 from being subjected to excessive tensile force, which could lead to breakage. Furthermore, the system can determine the pet's condition based on the detection results, providing a traction force and direction similar to that of a human leash, resulting in better traction and thus enhancing the user experience.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
