Description

Technical Field

[0001] The present application relates to the field of pet products, and in particular to a pet leash. Background Art

[0002] The existing pet traction device includes a shell, a traction disc rotatably arranged in the shell, and a traction rope wound on the traction disc. A coil spring is arranged in the traction disc, and the traction rope is used to pull the pet, and the traction rope is wound on the traction disc by the restoring force of the coil spring.

[0003] In the actual use of the pet leash, the activity space of the pet when being pulled is completely determined by the unwinding length of the leash. Therefore, in order to increase the activity space of the pet when being pulled, the unwinding length of the leash needs to be increased. If the unwinding length of the leash increases, the winding diameter of the coil spring used to wind up the leash also needs to be increased accordingly.

[0004] However, in the existing pet traction device, since the coil spring and the traction rope are respectively arranged on the inner and outer sides of the traction disk, the storage space of the coil spring and the winding space of the traction rope are limited by the traction disk, and both cannot accommodate a traction rope with a larger unwinding length and a coil spring with a larger winding diameter. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the present application provides a pet leash, which can effectively increase the winding space of the leash and the accommodating space of the coil spring.

[0006] The pet traction device provided in this application adopts the following technical solution:

[0007] A pet traction device comprises a shell, a traction disc rotatably arranged in the shell, a traction rope wound on the traction disc, and a rope opening on the shell for the traction rope to pass through. The traction disc is coaxially provided with a winding chamber on at least one side of its axial direction, and a winding spring is arranged in the winding chamber.

[0008] By adopting the above technical solution, a winding chamber for accommodating the coil spring is additionally provided on the side of the traction disk, so that the traction disk only needs to wind the traction rope without reserving installation space for the coil spring, which not only increases the winding space for the traction rope, but also ensures the accommodation space for the coil spring.

[0009] In a specific embodiment, the diameter of the winding chamber is larger than the diameter of the traction disk.

[0010] By adopting the above technical solution, the winding chamber with a larger diameter can accommodate a coil spring with a larger winding diameter, and the traction disc with a smaller diameter can wind a longer traction rope, which further increases the activity space of the pet when being pulled.

[0011] In a specific possible implementation manner, the winding chambers are respectively provided on both axial sides of the traction disk.

[0012] By adopting the above technical solution, two winding springs respectively arranged in the two winding chambers can respectively wind up the traction rope from both sides of the traction disk, effectively improving the balance of the traction rope during winding and releasing, and avoiding the deviation of the traction rope during winding and releasing.

[0013] In a specific possible implementation mode, mounting plates for mounting the winding chamber are respectively provided on both axial sides of the traction disk, and a traction groove for accommodating the traction rope is formed between the two mounting plates.

[0014] By adopting the above technical solution, the traction groove can limit the traction rope to prevent the traction rope from being offset when it is retracted or released.

[0015] In a specific implementation scheme, a limit block is further provided on the mounting plate, a movable locking member and a driving member for driving the locking member to move are provided in the housing, and the locking member can resist against or detach from the limit block.

[0016] By adopting the above technical solution, the locking member and the limiting block can cooperate with each other and realize the rotation locking of the traction disc, so that people can lock the traction rope in the unwinding state.

[0017] In a specific possible implementation scheme, the locking member is rotatably disposed in the housing and its rotation axis is parallel to the rotation axis of the traction plate. One end of the locking member is provided with a locking portion for resisting the limit block, and the other end is provided with a first transmission portion for cooperating with the driving member.

[0018] By adopting the above technical solution, the locking portion can abut against the limit block during the rotation of the locking member, thereby achieving rotation locking of the traction disk.

[0019] In a specific feasible implementation scheme, the locking portion includes a locking body and two locking heads respectively arranged at both ends of the locking body, the two locking heads are respectively located on the side of the two mounting plates away from each other, and each of the locking heads is respectively used to resist the limit block on the corresponding mounting plate.

[0020] By adopting the above technical solution, the two locking heads can respectively limit the limiting blocks on the two mounting plates, thereby improving the locking effect of the locking part on the traction disk.

[0021] In a specific feasible implementation scheme, a guide block is further provided on the locking body, and the guide block partially penetrates into the traction groove. The guide block is provided with a guide groove for the free end of the traction rope to pass through, and the rope opening is located on the side of the guide groove.

[0022] By adopting the above technical solution, it is effectively avoided that the free end of the traction rope is deviated before passing through the rope mouth, thereby affecting the traction effect on the pet.

[0023] In a specific feasible implementation scheme, the driving member is rotatably arranged in the outer shell around one end thereof and its rotation axis is parallel to the rotation axis of the locking member. The other end of the driving member is provided with a second transmission part, and the second transmission part is movably connected to the first transmission part. A pressing seat is also provided on the second transmission part, and the pressing seat is arranged outside the outer shell.

[0024] By adopting the above technical solution, the second transmission part can rotate and press the first transmission part under the action of the pressing seat, thereby driving the locking part to resist against the limit block or to separate from the limit block.

[0025] In a specific possible implementation scheme, a mounting ring is provided on the mounting plate, and the mounting ring is arranged on the circumference of the winding chamber. A plurality of the limit blocks are arranged on the mounting ring at intervals around the circumference thereof.

[0026] By adopting the above technical solution, the locking member can lock the traction disc at multiple rotation positions of the traction disc, which makes it easier for people to control the unwinding length of the traction rope.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] The pet leash of the present application has a winding chamber for accommodating a coil spring on the side of the traction disc, so that the traction disc only needs to wind the traction rope without reserving installation space for the coil spring, which not only increases the winding space for the traction rope, but also ensures the accommodation space for the coil spring.

[0036] The present application is further described in detail below in conjunction with the accompanying drawings.

[0037] See also Figure 1-5 As shown, a pet traction device is shown, including a shell 1, a traction disc 2 rotatably arranged in the shell 1, a traction rope (not shown in the figure) wound on the traction disc 2, and a rope opening 3 opened on the shell 1 for the traction rope to pass through. The traction disc 2 is respectively provided with a winding chamber 4 on both sides of its axial direction, and a coil spring (not shown in the figure) is arranged in the winding chamber 4. The specific installation method of the coil spring in the winding chamber 4 is the existing technology and will not be repeated here.

[0038] By additionally providing a winding chamber 4 for accommodating a coil spring on the side of the traction disc 2, the traction disc 2 only needs to wind the traction rope without reserving installation space for the coil spring, which not only increases the winding space for the traction rope, but also ensures the accommodation space for the coil spring. In this way, the relatively independent traction disc 2 and winding chamber 4 can respectively accommodate a traction rope and a coil spring of sufficient length, effectively increasing the activity space of the pet; at the same time, the two coil springs respectively arranged in the two winding chambers 4 can respectively wind the traction rope from both sides of the traction disc 2, effectively improving the balance of the traction rope when it is retracted and released, and avoiding the deviation of the traction rope when it is retracted and released.

[0039] In this embodiment, combined with Figure 2 As shown, the diameter of the winding chamber 4 is larger than the diameter of the traction disc 2. The larger diameter winding chamber 4 can accommodate a coil spring with a larger winding diameter, while the smaller diameter traction disc 2 can wind a longer traction rope, which further increases the activity space of the pet when being pulled.

[0040] Mounting plates 5 for mounting the winding chamber 4 are respectively arranged on both axial sides of the traction disc 2, and a traction groove 6 for accommodating the traction rope is formed between the two mounting plates 5. The traction groove 6 can limit the traction rope to prevent the traction rope from deflecting when it is retracted or released.

[0041] Combination Figure 4 As shown, the mounting plate 5 is also provided with a limit block 7, and the housing 1 is provided with a movable locking member 8 and a driving member 9 for driving the locking member 8 to move. The locking member 8 can resist the limit block 7 or be separated from the limit block 7. The locking member 8 is rotatably arranged in the housing 1 and its rotation axis is parallel to the rotation axis of the traction disk 2. One end of the locking member 8 is provided with a locking portion 81 for resisting the limit block 7, and the other end is provided with a first transmission portion 82 for cooperating with the driving member 9.

[0042] The locking member 8 and the limiting block 7 can cooperate with each other to realize the rotation locking of the traction disk 2, and the locking portion 81 can abut against the limiting block 7 during the rotation of the locking member 8, so that people can lock the traction rope in the unwinding state.

[0043] In this embodiment, combined with Figure 5 As shown, the locking portion 81 includes a locking body 811 and two locking heads 812 respectively disposed at both ends of the locking body 811. The two locking heads 812 are respectively located at the sides of the two mounting plates 5 that are away from each other. Each locking head 812 is used to resist the limiting block 7 on the corresponding mounting plate 5. The two locking heads 812 can limit the limiting blocks 7 on the two mounting plates 5, respectively, thereby improving the locking effect of the locking portion 81 on the traction disk 2.

[0044] Combine again Figure 5 As shown, the locking body 811 is also provided with a guide block 10, which is located between the two locking heads 812, and a portion of the guide block 10 is inserted into the traction groove 6. The guide block 10 is provided with a guide groove 11 for the free end of the traction rope to pass through, and the rope opening 3 is located on the side of the guide groove 11. The guide groove 11 can guide the free end of the traction rope, effectively preventing the free end of the traction rope from deviating before passing through the rope opening 3 and affecting its traction effect on the pet.

[0045] In this embodiment, combined with Figure 4 As shown, the driving member 9 is rotatably arranged around one end thereof in the housing 1 and its rotation axis is parallel to the rotation axis of the locking member 8. The other end of the driving member 9 is provided with a second transmission part 91, which is movably connected to the first transmission part 82. A pressing seat 92 is also provided on the second transmission part 91, and the pressing seat 92 is arranged outside the housing 1. The second transmission part 91 can rotate and squeeze the first transmission part 82 under the action of the pressing seat 92, thereby driving the locking part 81 to resist the limit block 7 or to separate from the limit block 7.

[0046] Specifically, when it is necessary to adjust the length of the traction rope, it is only necessary to press the pressing seat 92, the second transmission part 91 presses the first transmission part 82 downward, and the locking part 81 is driven by the first transmission part 82 to disengage from the limit block 7 upward, and the traction disk 2 can rotate freely at this time; and when it is necessary to lock the traction rope, it is only necessary to release the pressing seat 92, the first transmission part 82 loses the squeezing force and rotates upward, and the locking part 81 is driven by the first transmission part 82 to resist the limit block 7 downward, thereby locking the traction disk 2.

[0047] In this embodiment, long slots 911 are respectively provided on both sides of the second transmission part 91, and pins 821 are respectively provided on both sides of the first transmission part 82, and the two pins 821 are respectively slidably disposed in the two long slots 911. The cooperation between the pins 821 and the long slots 911 can keep the first transmission part 82 and the second transmission part 91 in the transmission state at all times, so as to avoid relative displacement between the two during the transmission process.

[0048] In this embodiment, a mounting ring 12 is provided on the mounting plate 5, and the mounting ring 12 is arranged around the circumference of the winding chamber 4. A plurality of limit blocks 7 are arranged at intervals around the circumference of the mounting ring 12. The plurality of limit blocks 7 correspond to the plurality of rotation positions of the traction disc 2, so that the locking member 8 can lock the traction disc 2 at the plurality of rotation positions of the traction disc 2, so that people can control the unwinding length of the traction rope.

[0049] In this embodiment, the housing 1 is further provided with a handle 13 for a person to hold.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
