Abstract
Description
Technical Field
[0001] This application relates to the field of pet products, and more specifically, to a leash for pets. Background Technology
[0002] Pets are becoming increasingly common in today's society. During the process of raising pets, owners and pets often go out together, such as when changing residences, taking walks, or training. Therefore, it is often necessary for owners to restrain or leash their pets, which has led to the development of pet leashes. However, most of them currently only use a flat strip of rope. When it is necessary to retract the leash, it can only be wrapped around the pet owner's hand, and the wrapped rope is also easy to loosen, making it inconvenient for pet owners to use. Utility Model Content
[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a pet leash, including a housing for a person to hold. Inside the housing, a drum for winding and unwinding the leash is rotatably arranged. A first ratchet and a second ratchet, which rotate coaxially with the drum, are respectively arranged on the front and rear sides of the drum. Inside the housing, a pawl is also elastically arranged, which meshes with the first and second ratchet gears simultaneously. A rocker arm is movably arranged on the front side of the housing and is driven to the drum. The rocker arm drives the drum, along with the first and second ratchets, to rotate synchronously inside the housing, thereby realizing the winding action of the leash.
[0004] Preferably, the front side of the drum is further provided with a first connecting piece that rotates coaxially with it, and the first connecting piece is located inside the first ratchet. A first groove is formed on the outer side of the first connecting piece, and a first locking block is formed on the inner side of the first ratchet that engages with the first groove. The drum drives the first ratchet through the interaction between the first groove and the first locking block. The back side of the drum is further provided with a second connecting piece that rotates coaxially with it, and the second connecting piece is located inside the second ratchet. A second groove is formed on the outer side of the second connecting piece, and a second locking block is formed on the inner side of the second ratchet that engages with the second groove. The drum drives the second ratchet simultaneously through the interaction between the second groove and the second locking block.
[0005] Preferably, the top of the housing is provided with a limiting plate that is hinged to the front and rear sides of the pawl, and a push block is movably installed inside the limiting plate. The push block moves left and right within the limiting plate. The bottom of the push block is formed with a hook that moves synchronously with it. A limiting rod is formed inside the housing, and the hook is hooked onto the limiting rod for position limiting.
[0006] Preferably, a first spring is provided between the left side of the hook and the right side of the limiting plate to drive the hook to elastically reset, and the two ends of the first spring are elastically connected to the hook and the limiting plate respectively. A second spring is provided between the bottom of the limiting plate and the inside of the housing to drive the limiting plate to elastically reset, and the two ends of the second spring are elastically connected to the limiting plate and the housing respectively.
[0007] Preferably, the top of the housing is also provided with a threading port for the traction rope to enter and exit inside it.
[0008] In summary, the beneficial effects of this application are as follows:
[0009] Pet owners simply need to first engage the pawl with both the first and second ratchet gears simultaneously, then hold the lever and rotate it clockwise on the side of the housing. At this time, the drum, the first ratchet, and the second ratchet will rotate synchronously under the lever's influence. Through the cooperation of these structures, the leash can be retracted. During this process, the pawl will slide across the backs of the teeth of both the first and second ratchet gears. When an external force pulls the leash out of the housing again, the pawl will prevent the first and second ratchet gears from rotating counterclockwise. Through the cooperation of the pawl, the first and second ratchet gears, the first and second ratchet gears, and the drum can only perform unidirectional intermittent motion. The leash wound on the drum will not slip out of the housing, preventing inconvenience for the pet owner. Furthermore, the pet owner can pull out the desired leash length and automatically maintain the leash at that length, improving user comfort. Attached Figure Description

[0019] A pet leash, see Figures 1 to 4The device includes a housing 1 for gripping, inside which a drum 2 (not shown in the figure) is rotatably mounted to wind up and unwind a traction rope. A first ratchet 3 and a second ratchet 4, coaxially rotating with the drum 2, are respectively located on the front and rear sides of the drum 2. A pawl 5, elastically mounted inside the housing 1, simultaneously meshes with the first ratchet 3 and the second ratchet 4. A rocker arm 6 is movably mounted on the front side of the housing 1, and the rocker arm 6 is driven by the drum 2. The rocker arm 6 drives the drum 2, along with the first ratchet 3 and the second ratchet 4, to rotate synchronously inside the housing 1, thereby achieving the winding up of the traction rope. In this embodiment, the pet... The owner simply holds the housing 1 with one hand and pulls the leash at one end of the housing 1 outwards with the other, or ties the leash at one end of the housing 1 to the pet and lets the pet pull the leash outwards. This lengthens the leash outside the housing 1. During this process, the pawl 5 does not contact the first ratchet 3 and the second ratchet 4, and the drum 2, driven by the leash, drives the first ratchet 3 and the second ratchet 4 to rotate counterclockwise simultaneously inside the housing 1. The rocker arm 6 also rotates counterclockwise synchronously on the side of the housing 1, driven by the drum 2. When it is necessary to wind the leash outside the housing 1 back onto the drum 2 for winding... When reeling in the leash, the pet owner simply needs to first engage the pawl 5 with both the first ratchet 3 and the second ratchet 4, then grasp the rocker arm 6 and rotate it clockwise on the side of the housing 1. At this time, the drum 2, the first ratchet 3, and the second ratchet 4 will rotate synchronously under the influence of the rocker arm 6. Through the cooperation of these structures, the leash can be reeled in. During this process, the pawl 5 will slide across the back of the teeth of both the first ratchet 3 and the second ratchet 4. When an external force pulls the leash out of the housing 1 again, the pawl 5 will prevent the first ratchet 3 and the second ratchet 4 from rotating counterclockwise. The first ratchet 3 and the second ratchet 4 work together so that the first ratchet 3, the second ratchet 4 and the drum 2 can only make unidirectional intermittent movements. The leash wound on the drum 2 will not slip out of the housing 1, which would be inconvenient for the pet owner. Moreover, the pet owner can pull out the required length of leash as needed and the leash will be automatically kept at that length, which improves the comfort of use. This effectively solves the technical problem that most of the current methods only use a flat strip of rope, which can only be wound around the pet owner's hand when it needs to be wound up. Moreover, the wound rope is easy to loosen, which makes it inconvenient for the pet owner to use.
[0020] The drum 2 is further provided with a first connecting piece 7 that rotates coaxially with it on its front side. The first connecting piece 7 is located inside the first ratchet 3, and a first groove 8 is formed on the outer side of the first connecting piece 7. A first locking block 9 is formed on the inner side of the first ratchet 3 that engages with the first groove 8. The drum 2 drives the first ratchet 3 through the interaction between the first groove 8 and the first locking block 9. The drum 2 is further provided with a second connecting piece 10 that rotates coaxially with it on its back side. The second connecting piece 10 is located inside the second ratchet 4, and a second groove 11 is formed on the outer side of the second connecting piece 10. A second locking block 9 is formed on the inner side of the second ratchet 4 that engages with the second locking block 9. The second locking block 12 engages with the slot 11, and the drum 2 simultaneously drives the second ratchet 4 through the mutual cooperation between the second slot 11 and the second locking block 12. In this embodiment, the slot-block engagement design between the first connecting piece 7 and the first ratchet 3, and the second connecting piece 10 and the second ratchet 4, enables the drum 2 to quickly drive the first ratchet 3 and the second ratchet 4. Furthermore, the drum 2 synchronously drives the first ratchet 3 and the second ratchet 4 through the front and rear double connecting pieces, forming a dual transmission path. This ensures that even if one side of the engagement structure breaks accidentally, the remaining side can still maintain the transmission function, effectively improving the practicality of this embodiment.
[0021] The top of the housing 1 is provided with a limiting plate 13 that is hinged to the front and rear sides of the pawl 5. A push block 14 is movably installed inside the limiting plate 13 and moves left and right within the limiting plate 13. A hook 15 that moves synchronously with the push block 14 is formed at the bottom of the push block 14. A limiting rod 16 is formed inside the housing 1, and the hook 15 is hooked onto the limiting rod 16 for position limitation. A first spring 17 is provided between the left side of the hook 15 and the right side of the limiting plate 13 to drive the hook 15 to elastically return to its original position. The first spring 17 is elastically connected at both ends to the pawl 15 and the limiting plate 13, respectively. A second spring 18 is provided between the bottom of the limiting plate 13 and the inside of the housing 1 to drive the limiting plate 13 to elastically reset. The two ends of the second spring 18 are elastically connected to the limiting plate 13 and the housing 1, respectively. In this embodiment, when the drum 2 drives the first ratchet 3 and the second ratchet 4 to rotate counterclockwise simultaneously inside the housing 1 under the drive of the traction rope, the pawl 5 does not contact the first ratchet 3 and the second ratchet 4, and the push block 1... Position 4 is located on the left side within the limiting plate 13. The first spring 17 undergoes elastic deformation under the action of the push block 14. At this time, the second spring 18 is in its natural state and drives the right side of both the limiting plate 13 and the push block 14 to tilt upwards simultaneously. The pawl 15 will be positioned on the side of the limiting rod 16 under the action of the push block 14, and the pawl 15 and the limiting rod 16 will not contact each other. When the rocker arm 6 is grasped and rotated clockwise on the side of the housing 1, the pawl 5 simultaneously meshes with the first ratchet 3 and the second ratchet 4. The push block 14 is located on the right side within the limiting plate 13. At this time, the push block 14 does not apply pressure to the first spring 17, and the first spring 17 will be in a natural state. Meanwhile, the limiting plate 13 and the push block 14 will simultaneously apply pressure to the second spring 18 and cause it to undergo elastic deformation, thereby driving the hook 15 to hook onto the limiting rod 16. Through the cooperation between the above structures, it can be ensured that the drum 2 is absolutely locked during the winding process, preventing structural failure caused by external violent pulling, and further improving the practicality of this embodiment.
[0022] The top of the housing 1 is also provided with a threading port 19 for the traction rope to enter and exit inside it.
[0023] The above embodiments are merely explanations of this application and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
