Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, specifically to a novel dog leash. Background Technology

[0002] In daily life, large dogs are prone to sudden lunging behaviors when stimulated by external stimuli. This behavior can not only injure the pet itself but also endanger its owner or others. Traditional leash methods rely primarily on the owner's strength and reaction speed to control sudden dog movements. However, this method often proves inadequate when faced with the strong pulls of large breeds. Owners may be unable to control their dogs in time, leading to loss of control and accidents. Existing methods to prevent sudden lunging involve a fixed leash connected to a handle and the pet's collar or harness, or sensors that detect the pet's instantaneous speed and automatically lock the leash. However, both of these methods rely on a single leash mechanism. When the dog pulls strongly, the leash may slip from the owner's hand, or the dog may drag the owner with the leash, causing accidents and failing to effectively control the lunging pet. Therefore, there is an urgent need in the market for a new type of leash that can effectively control dogs in a lunging state to improve the safety of pets and those around them. Utility Model Content

[0003] In view of the above problems, this utility model provides a new type of dog leash to solve the problem that existing dog leashes cannot effectively control pet dogs in a sudden, explosive state.

[0004] According to one aspect of the present invention, a novel dog leash is provided, the novel dog leash comprising:

[0005] A leash assembly includes a handle, a first leash, a second leash, and a wearable device. The wearable device is fitted onto the body of a pet dog. The two ends of the first leash are connected to the handle and the wearable device, respectively, and one end of the second leash is connected to the handle.

[0006] At least two restraints are provided for connection to the lower limbs of the pet.

[0007] A telescopic control assembly includes a hollow housing and a drive unit, a control board, a rotating drum, and a telescopic rope disposed within the housing; the rotating drum is fixed to the output shaft of the drive unit, and the drive unit is electrically connected to the control board;

[0008] A tension sensor, wherein one tension transmission end of the tension sensor is fixedly connected to the wearable device, and the other tension transmission end is connected to the end of the second traction rope away from the handle; and the signal output end of the tension sensor is electrically connected to the control board.

[0009] An opening is provided on the housing. The first end of the telescopic rope is wound around the central axis of the rotating drum and connected to the rotating drum. The second end of the telescopic rope passes through the opening and is placed outside the housing. The second end is connected to the restraining member in sequence and fixed to any one of the restraining members.

[0010] The second traction rope is longer than the first traction rope.

[0011] In one alternative embodiment, the drive unit is a bidirectional motor, and the tension sensor sends a signal to the control board for the control board to control the output shaft of the drive unit to rotate in the forward direction, thereby driving the rotating drum to rotate in the forward direction so that the second end moves toward the housing to shorten the distance between the lower limbs on which the restraint member is fitted.

[0012] A start button is provided on the housing. The start button is connected to the control board and transmits a release signal to the control board. The release signal is used to control the drive component to rotate in the opposite direction, thereby causing the rotating drum to rotate in the opposite direction to release the retracted telescopic rope, which is used to adjust the distance between the lower limbs on which the restraint is fitted.

[0013] In one alternative embodiment, the control board is provided with a feedback circuit for detecting the current of the driving device and determining whether the current exceeds a threshold. When the current exceeds the threshold, the control board controls the driving device to stop working.

[0014] In one alternative embodiment, the novel dog leash includes a first restraint member and a second restraint member; the first restraint member is provided with a first connecting ring, and the second restraint member is provided with a second connecting ring;

[0015] The second end of the telescopic rope is connected to the first connecting ring and the second connecting ring, and is fixed to either the first connecting ring or the second connecting ring.

[0016] In one alternative embodiment, the first restraint and the second restraint are fitted onto the pet's two adjacent lower limbs.

[0017] In one alternative embodiment, an elastic sleeve is provided in the first restraint member, and the telescopic control component is placed inside the sleeve and elastically fixedly connected to the elastic sleeve.

[0018] In one alternative, the opening is located at the enlarged end of the housing, which is located outside the sleeve.

[0019] In one alternative embodiment, the wearable device includes an abdominal end that conforms to the abdomen of the pet's body, with the telescopic control assembly mounted on the side of the abdominal end away from the pet's body.

[0020] In one alternative embodiment, the first restraint member and the second restraint member are integrally connected to the wearable device at one end in the vertical direction.

[0021] In one alternative embodiment, the rotating drum includes an upper flange and a lower flange, with a rotating shaft disposed between the upper flange and the lower flange; the telescopic rope is wound around the rotating shaft;

[0022] The distance between the upper flange and the lower flange is less than twice the width of the telescopic rope.

[0023] This invention provides a novel dog leash that effectively controls sudden pet behavior, improving the safety of both the dog and those around it. By attaching a wearable component to the dog's body, a first leash connects a handle and the wearable component for leash control during walks. A second leash connects to the handle and extends through a tension sensor and a telescopic control assembly to a restraint piece fitted around the dog's lower limbs. When the dog's pulling force reaches a preset threshold, the telescopic control assembly controls the movement and force exertion of the dog's lower limbs, thereby controlling any sudden, explosive behavior. This embodiment, through dual leash control, allows the owner to more effectively control their pet's actions. The second leash, via the telescopic control assembly, allows the leash to retract into the housing of the telescopic control assembly when the pet lunges, shortening the distance between at least two of the pet's lower limbs and preventing the pet's lower limbs from exerting force and moving, thus limiting the sudden lunge.

[0024] The telescopic control assembly includes a hollow housing, a drive unit, a control board, a rotating drum, and a telescopic rope. The rotating drum is fixed to the output shaft of the drive unit, which is electrically connected to the control board. One end of the telescopic rope is wound around the rotating drum, and the other end is connected to a restraint component. The telescopic rope can dynamically adjust its length according to the pet's behavior. When the pet is walking normally, the portion of the telescopic rope outside the housing maintains a longer length, ensuring the dog can walk or run normally. When the pet suddenly lunges forward, it pulls the second leash forcefully, causing the tension sensor to transmit a signal to the control board through its signal output terminal. The control board determines whether to activate the drive unit based on the received signal. When the control board determines that the tension of the second leash exceeds a tension threshold, it activates the drive unit, causing the output shaft to rotate and rotating the drum. This retracts the second end of the telescopic rope into the housing, shortening the distance between the dog's hind limbs through the restraint component, thus effectively preventing the pet from lunging forward.

[0025] In this embodiment of the invention, the second leash is longer than the first leash. When the dog is in a normal state, the owner can control its movement using the first leash, while the second leash is relaxed. When the dog exhibits sudden, aggressive behavior, the owner pulls the second leash, applying force to a tension sensor. The tension sensor transmits a signal to the control board of the telescopic control assembly in real time. The control board controls the drive unit based on the received signal, driving the output shaft to rotate and thus rotating the drum. This retracts the telescopic leash into the housing, causing the second end of the leash to move towards the housing, shortening the distance between the lower limbs fitted with restraints, limiting the dog's lower limb exertion and movement, and effectively controlling the dog's sudden behavior.

[0026] In summary, this utility model, through the use of dual traction ropes, telescopic control components, tension sensors, and restraints to restrain the lower limbs at multiple points, enables owners to more effectively respond to sudden behaviors of their pets, reducing safety risks to pets and surrounding people. It not only improves pet management efficiency but also enhances the user experience, and has broad application prospects.

[0043] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0044] Please see Figures 1-8 ,like Figure 1As shown in the figure, this utility model provides a perspective view of a novel dog leash, which includes: a traction component 1, at least two restraint members 2, a telescopic control component 3, and a tension sensor 4. The restraint members 2 are used to connect and attach to the pet's lower limbs. Figure 2 As shown, the leash assembly 1 includes a handle 11, a first leash 12, a second leash 13, and a wearer 14. The wearer 14 is fitted onto the dog's body. The two ends of the first leash 12 are connected to the handle 11 and the wearer 14, respectively. One end of the second leash 13 is connected to the handle 11, and the second leash 13 is longer than the first leash 12. Figure 7 As shown, the telescopic control assembly 3 includes a hollow housing 31 and a drive unit 32, a control board 33, a rotating drum 34, and a telescopic rope 35 disposed within the housing 31; the rotating drum 34 is fixed to the output shaft of the drive unit 32, and the drive unit 32 is electrically connected to the control board 33. Figure 5 As shown, the tension sensor 4 includes two tension transmission ends 41 and one signal output end 42. One tension transmission end 41 of the tension sensor 4 is fixedly connected to the wearable device 14, and the other tension transmission end 41 is connected to the end of the second traction rope 13 away from the handle 11. The signal output end 42 is electrically connected to the control board 33. Figure 6 As shown, an opening 311 is provided on the housing 31. The first end of the telescopic rope 35 is wound around the central axis of the rotating drum 34 and connected to the rotating drum 34. The second end 351 of the telescopic rope 35 passes through the opening 311 and is placed outside the housing 31. The second end 351 is sequentially movably connected to at least one restraining member 4 and fixed to one restraining member 4.

[0045] Specifically, such as Figure 2 As shown, the wearable device 14 includes a neck collar 143 and a body collar 144. The neck collar 143 and the body collar 144 are connected by a back end 142 and an abdominal end 141. The neck collar 143 is used to fit around the neck of the pet dog and its tightness is adjusted by a movable buckle. The body collar 144 is fitted around the body of the pet dog between its fore and hind limbs and its tightness is adjusted by a movable buckle according to the size of the pet dog. The back end 142 is used to connect the neck collar 143 and the body collar 144 at the back of the pet dog. At the same time, a fixing part 145 is provided along the back end 142. The two ends of the fixing part 145 are fixed to the back end 142 in the length direction. The middle end located between the two ends of the fixing part 145 is separated from the back end 142. A third connecting ring 146 is fitted on the fixing part 145. The first leash 12 and the third connecting ring 146 are connected to realize the connection between the first leash 12 and the wearable device 14, so as to control the pet dog's free movement.

[0046] like Figure 5As shown, one tension transmission end 41 of the tension sensor 4 is connected to the third connecting ring 146, and the other tension transmission end 41 is connected to the second leash 13, so as to realize the connection between the second leash 13 and the wearable device 14. When the pet dog suddenly charges, by pulling the second leash 13, the tension sensor 4 is subjected to the tension on both sides of the second leash 13 and the wearable device 14, so that the tension sensor 4 generates a tension signal and transmits the signal to the control board 33 through the signal output end 42. The control board 33 determines whether the tension of the second leash 13 is greater than the tension threshold based on the received signal. When the control board 33... 3. When the received signal indicates that the tension of the second traction rope 13 is greater than the tension threshold, the control board 33 controls the drive component 32 to work, drives the output shaft to rotate and drives the drum 34 to rotate. The drum 34 drives the telescopic rope 35 to rotate, moving the second end 351 of the telescopic rope 35 into the housing 31 to retract. During the retraction process, the second end 351 of the telescopic rope 35 shortens the connection distance between the telescopic rope 35 and the different restraints 4, thereby causing at least two restraints 4 to move closer to each other, shortening the distance between the lower limbs of the pet dog, thus effectively preventing the pet from lunging.

[0047] An electrical connection opening (not shown in the figure) is provided on the housing 31. This electrical connection opening is used to electrically connect the signal output terminal 42 of the tension sensor 4 to the control board 33, so that the signal of the tension sensor 4 can be transmitted to the control board 33. When the pet exhibits sudden behavior, the second traction rope 13, tension sensor 4, and control board 33 can be used to start the drive unit 32 to work in time, and promptly control the second end 351 of the telescopic rope 35 to wrap around the rotating drum 34 inside the housing 31, reduce the distance between the pet's lower limbs, and limit the force exertion and movement of the pet's lower limbs.

[0048] like Figure 7 and Figure 8 As shown, a power supply component 36 is also provided inside the housing 31. A charging port is provided on one end face of the housing 31 along its length. An electrical power supply is provided to the power supply component 36 through this charging port. The power supply component 36 and the control board 33 are electrically connected to supply power to the circuit board and the drive component 32. A snap-fit ​​part 313 is provided inside the housing 31. The power supply component 36, the control board 33, and the drive component 32 are fixedly connected to the housing 31 through snap-fit ​​parts 313 at different positions. The rotating drum 34 is spaced apart from the inner wall of the housing 31. When the drive component 32 drives the output shaft to rotate, the rotating drum 34 rotates inside the housing 31 under the rotation of the output shaft to achieve the effect of retracting the telescopic rope 35.

[0049] The restraint 4 is an elastic tubular knot, which is fitted onto the lower limbs to connect the restraint 4 to the pet's lower limbs.

[0050] In another implementation, such as Figure 6As shown, the restraint 4 includes a wrapping part 26 and multiple straps 27 on the edge of the wrapping part 26. The straps 27 are made of elastic fabric. The wrapping part 26 is used to wrap the lower limbs in close contact. The straps 27 are used to tie the wrapping part 26 to the lower limbs of the pet. Alternatively, the restraint 4 can be made of Velcro. The outer side of the wrapping part 26 away from the surface of the lower limbs is made of fur. The side of the straps 27 that contacts the wrapping part 26 is made of hook. The restraint 4 is fixed to the lower limbs by the straps 27 and the wrapping part 26.

[0051] In one implementation, such as Figure 3 and Figure 4 As shown, the lengths of the first traction rope 12 and the second traction rope 13 are adjustable. The traction assembly 1 also includes two turntables 15, which are installed side by side inside the handle 11. The first traction rope 12 and the second traction rope 13 are respectively wound around one of the turntables 15 and connected. The handle 11 is provided with two rope outlets 111. The other end of the first traction rope 12 passes through one rope outlet 111 and is placed outside the handle 11 for connection with the wearable device 14. The other end of the second traction rope 13 passes through the other rope outlet 111 and is placed outside the handle 11 for fixed connection with a tension transmission end 41 of the tension sensor 4.

[0052] like Figure 3 and Figure 4 As shown, each turntable 15 is provided with an adjusting member 16. The adjusting member 16 includes a pressing part 161, a first pressing rod 162, a second pressing rod 163, an abutting part 164, and a pressing part 165. The pressing part 165 has a groove 166 for accommodating the traction rope. The pressing part 161 is located outside the handle 11. One end of the second pressing rod 163 is fixedly connected to the pressing part 161 via a connecting shaft 167, and the other end is placed at the upper end of the groove 166 of the pressing part 165. The connecting shaft 167 is perpendicular to the length direction of the second pressing rod 163, and both ends are fixed to the inner wall of the handle 11. The first pressing rod 162 is shorter than the second pressing rod 163 and is placed parallel to the second pressing rod 163. One end of the first pressing rod 162 contacts the bottom of the pressing member, and the other end points to the abutment part 164. An elastic member 168 is sleeved at the middle position of the first pressing rod 162 and the second pressing rod 163.

[0053] Because the second pressing rod 163 is longer than the first pressing rod 162, when the pressing part 161 is not subjected to external force, the second pressing rod 163 is embedded in the groove 166, and interacts with the pressing part 165 to squeeze the traction rope located in the groove 166 to fix the traction rope, thereby fixing the traction rope; when it is necessary to adjust the length of the traction rope, the pressing part 161 is pressed down.

[0054] Under the action of the connecting shaft 167, the pressing part 161 will rotate at a certain angle, causing the second pressing rod 163 to move away from the groove 166. The traction rope is released, and the length can be adjusted by manually pulling the first traction rope 12 and the second traction rope 13. At this time, the first pressing rod 162 will move towards the abutting part 164 under the action of the pressing part 161. The abutting part 164 is used to support the pressing part 161 through the first pressing rod 162 to prevent the pressing part 161 from continuing to rotate. When the adjustment of the first traction rope 12 and the second traction rope 13 is completed, the pressing part 161 is released. Under the action of the elastic element 168 and the connecting shaft 167, the second pressing rod 163 moves towards the groove 166 of the pressing part 165 to squeeze and lock the traction rope in the groove 166.

[0055] In another implementation, the lengths of the first traction rope 12 and the second traction rope 13 are not adjustable. The second traction rope 13 is longer than the first traction rope 12, so that when the first traction rope 12 is pulled, the second traction rope 13 does not have a pulling effect. At this time, the tension acting on the tension sensor 4 is less than the tension threshold, and the drive unit 32 is in a non-working state.

[0056] In this embodiment, the wearable device 14 is fitted onto the dog's body. The first leash 12 connects the handle 11 and the wearable device 14 for leash control during dog walking. The second leash 13 connects the handle 11 and extends through the tension sensor 4 and the telescopic control assembly 3 to the restraint 4 fitted onto the dog's lower limbs, for controlling the movement and force exertion of the dog's lower limbs. This embodiment, through dual leash control, allows the owner to more effectively control the pet's actions. The second leash 13, via the telescopic control assembly 3, allows the telescopic rope 35 to retract into the housing 31 of the telescopic control assembly 3 when the pet lunges, shortening the distance between at least two of the pet's lower limbs and preventing the pet's lower limbs from exerting force and moving, thus limiting the pet's lunge.

[0057] In one embodiment of this utility model, the drive component 32 is a bidirectional motor. The tension sensor 4 sends a signal to the control board 33, which controls the output shaft of the drive component 32 to rotate in the forward direction, thereby driving the rotating drum 34 to rotate in the forward direction and controlling the second end 351 of the telescopic rope 35 to move towards the housing 31 to shorten the distance between the lower limbs covered with the restraint member 4. A start button is provided on the housing 31. The start button is connected to the control board 33 and transmits a release signal to the control board 33. The release signal is used to control the drive component 32 to rotate in the reverse direction, thereby driving the rotating drum 34 to rotate in the reverse direction to release the contracted telescopic rope 35, which is used to adjust the distance between the lower limbs covered with the restraint member 4. By employing a bidirectional motor, the distance between the lower limbs of the pet dog equipped with restraint 4 is adjusted: When the owner pulls the second leash 13, the tension sensor 4 sends a signal to the control board 33 through the signal output terminal 42. The control board 33 determines that the pet dog has suddenly lunged based on the signal, and controls the output shaft of the drive unit 32 to rotate in the forward direction, thereby driving the rotating drum 34 to rotate in the forward direction and controlling the telescopic rope 35 to move around the central axis of the rotating drum 34. The second end 351 of the telescopic rope 35 moves towards the housing 31 to shorten the distance between the lower limbs equipped with restraint 4. When the pet dog calms down or is controlled, the start button is pressed to send a release signal to the control board 33. The control board 33 controls the drive unit 32 to rotate in the reverse direction based on the release signal, thereby driving the rotating drum 34 to rotate in the reverse direction and releasing the retracted telescopic rope 35 to adjust the distance between the lower limbs equipped with restraint 4.

[0058] The control board 33 is equipped with a feedback circuit to detect the current of the drive component 32 and determine whether the current exceeds a threshold. When the current exceeds the threshold, the control board 33 controls the drive component 32 to stop working. The detection principle is as follows: When the telescopic rope 35 is tightened, the tension is applied to the output shaft through the rotating drum 34, increasing the load on the drive component 32. Therefore, the drive component 32 requires more current to continue rotating. To avoid overload of the drive component 32 and excessive retraction of the telescopic rope 35 that could injure the dog's hind limbs, a feedback circuit is provided on the control board 33. This feedback circuit uses a Hall effect sensor to monitor the current of the drive component 32. When the current exceeds the current threshold, the control board 33 controls the drive component 32 to stop rotating, preventing the telescopic rope 35 from further retracting into the housing 31. This protects the dog's hind limbs from injury and prevents overload of the drive component 32.

[0059] In another embodiment, an encoder is installed on the feedback circuit to detect the retracted length of the telescopic rope 35. When the encoder detects that the retracted length has reached a threshold, the control board 33 controls the drive unit 32 to stop rotating, so that the telescopic rope 35 is no longer retracted into the housing 31, thereby protecting the dog's hind limbs from injury.

[0060] In one implementation of this embodiment, such as Figure 6 As shown, the new dog leash includes a first restraint member 21 and a second restraint member 22; the first restraint member 21 is provided with a first connecting ring 23, and the second restraint member 22 is provided with a second connecting ring 24; the second end 351 of the telescopic rope 35 is connected to the first connecting ring 23 and the second connecting ring 24, and is fixed to either the first connecting ring 23 or the second connecting ring 24.

[0061] By setting a first connecting ring 23 in the first restraint member 21 and a second connecting ring 24 in the second restraint member 22, the second end 351 of the telescopic rope 35 can quickly pass through the first connecting ring 23 and the second connecting ring 24, thereby achieving a quick connection between the first restraint member 21 and the second restraint member 22. When the pet lunges, the tension of the telescopic rope 35 acts on the first restraint member 21 and the second restraint member 22 through the first connecting ring 23 and the second connecting ring 24, and then acts on the pet's lower limbs. The first restraint member 21 and the second restraint member 22 can increase the contact area of ​​the force and the surface force of the lower limbs, protecting the pet from injury. The telescopic rope 35 can move quickly and unimpeded within the first connecting ring 23 and the second connecting ring 24, so that the telescopic rope 35 can move quickly and unimpeded during the tightening process into the housing 31, thereby quickly restricting the pet's movement.

[0062] The first restraint piece 21 and the second restraint piece 22 are fitted onto the pet's two adjacent lower limbs. The two adjacent lower limbs include: two forelegs, two hindlegs, or one foreleg and one hindleg. By restricting the force exertion and movement of the two adjacent lower limbs, the dog's sudden lunge is restricted.

[0063] In one implementation, such as Figure 6 As shown, an elastic sleeve 25 is provided on the first restraint member 21, and the telescopic control component 3 is placed inside the sleeve and elastically fixedly connected to the elastic sleeve 25. The elasticity of the elastic sleeve 25 secures the telescopic control component 3 within it, ensuring that the telescopic control component 3 remains stable during pet activity and will not loosen or shift due to external forces. Even in the event of a sudden lunge by the pet, the telescopic control component 3 can remain in the correct position, ensuring the normal contraction of the telescopic rope 35.

[0064] The housing 31 includes an enlarged end 312. When the telescopic control assembly 3 is fixed inside the elastic sleeve 25, the enlarged end 312 is located outside the sleeve, and the opening 311 is located on one side of the enlarged end 312 of the housing 31. The housing 31 is arranged with one end larger and the other smaller in the length direction. The rotating drum 34 is located at the enlarged end 312, and the drive unit 32, power supply unit 36, and control board 33 are located at the smaller end. Therefore, the end of the housing 31 used to accommodate the rotating drum 34 and the telescopic rope 35 needs a larger space to ensure that there is enough space inside the housing 31 for the rotating drum 34 to rotate to wind, tighten, or release the telescopic rope 35. Different sizes are set at the positions on the housing 31 where different components are installed, so that the telescopic control assembly 3 is compact and the housing 31 is not too large and inconvenient for pets to carry. When the telescopic control assembly 3 is placed inside the sleeve, the enlarged end 312 of the housing 31 is located outside the sleeve, and the opening 311 on the enlarged end 312 is also located outside the sleeve, so that the contraction or release of the telescopic rope 35 can be carried out smoothly.

[0065] The first restraint member 21 and the second restraint member 22 are integrally connected to the wearer 14 at one end in the vertical direction, so that the wearer 14 can provide a vertical upward pulling force to the restraint member, prevent the restraint member from slipping down, and ensure that the restraint member and the telescopic control component 3 installed in the sleeve are in the position close to the drive of the pet's limbs, so as to prevent the telescopic rope 35 and the restraint member from slipping down and hindering the pet's normal movement.

[0066] In another implementation, the wearable device 14 includes an abdominal end 141 that fits snugly against the pet's abdomen, with the telescopic control component 3 mounted on the side of the abdominal end 141 away from the pet's body. During normal dog movement or charging, the relative position of the wearable device 14 and the dog does not change significantly. Mounting the telescopic control component 3 on the abdominal end 141 ensures a relatively fixed position between the telescopic control component 3 and the dog, guaranteeing a stable electrical connection between the signal output terminal 42 of the tension sensor 4 and the control board 33 within the telescopic control component 3.

[0067] An electrical connection port (not shown in the figure) is provided on the housing 31. One end of the wire 5 passes through the electrical connection port and is electrically connected to the control board 33, and the other end is connected to the signal output terminal 42 of the tension sensor 4, so that when the second traction rope 13 is pulled hard on the tension sensor 4, the tension sensor 4 can transmit a signal to the control board 33 in a timely and stable manner.

[0068] The wearable part 14 is made of fabric. The wire 5 is placed inside the wearable part 14 to ensure a stable connection of the wire 5, while keeping the appearance of the dog leash neat and avoiding messiness.

[0069] like Figure 8As shown, the rotating drum 34 includes an upper flange 341 and a lower flange 342, and a rotating shaft 343 is provided between the upper flange 341 and the lower flange 342; the telescopic rope 35 is wound around the rotating shaft 343; wherein, the distance between the upper flange 341 and the lower flange 342 is less than twice the width of the telescopic rope 35.

[0070] The lower flange 342 is positioned close to the drive member 32, and the upper flange 341 is positioned away from the drive member 32. The output shaft passes through the lower flange 342 and is placed inside the rotating shaft 343 and is fixedly connected to the rotating shaft 343. When the drive member 32 drives the output shaft to rotate, the rotating shaft 343 and the upper flange 341 and lower flange 342 fixedly connected to both ends of the rotating shaft 343 rotate accordingly, causing the telescopic rope 35 wound on the rotating shaft 343 to be released or stretched and wound.

[0071] The upper flange 341 and lower flange 342 ensure that the telescopic rope 35 remains between them during the overwinding process, preventing the rope from becoming tangled and thus hindering its proper tightening or release. Simultaneously, the distance between the upper and lower flanges 342 is less than twice the width of the telescopic rope 35 but greater than one times its width, further ensuring that the rope is wound in an orderly manner during rotation and guaranteeing a smooth release process.

[0072] This invention provides a novel dog leash that effectively controls sudden behaviors of large pets, significantly improving the safety of pets and those around them. Through the coordinated operation of the first leash 12, the second leash 13, the telescopic control assembly 3, and the tension sensor 4, pulling the first leash 12 during a walk allows the dog to move normally. When the pet suddenly lunges forward, the second leash 13 is quickly pulled, and the pulling force acts on the tension sensor 4. The tension sensor 4 sends a signal to the control board 33 within the telescopic control assembly 3. The control board 33 judges the force based on the received signal. If the force on the second leash 13 exceeds a threshold, the drive unit 32 is activated, driving the output shaft to rotate, which in turn rotates the drum 34. This causes the second end 351 of the telescopic leash 35 to move into the housing 31, shortening the distance between the dog's hind limbs, limiting the force and movement of the hind limbs, preventing sudden lunging behavior, and reducing safety risks for pets and those around them. This not only improves pet management efficiency but also enhances the user experience, demonstrating broad application prospects.
