Problems solved by technology
This kind of pet leash includes an automatic winding function and a locking function at a certain length of the rope, but due to the limited space in the ring-shaped leash housing, the space for installing the coil spring is limited, and the volume of the coil spring is limited. The number of turns that can rotate with the second gear to store energy is limited, the number of turns of the winding shaft is limited, and only a few turns can be made, so the length of the rope is limited, and the rope cannot be too long
It is necessary to expand the size of the entire leash assembly to extend the length of the rope, which leads to a significant increase in the weight and volume of the entire leash assembly, which is inconvenient to use, and the torque output by the coil spring is large when it is tightened, and it is close to the full length. When relaxing, the output torque will decrease a lot, resulting in uneven pulling force of the coil spring on the rope, and too much pulling force is required when the tail is pulled out of the rope

The invention discloses a pet pulling rope. The rope comprises a shell forming a hollow annular channel, a rope outlet is formed in the shell, a rope winding ring is arranged in the annular channel, the rope is wound on the periphery of the rope winding ring, a braking mechanism and a rope winding mechanism are arranged on the shell, a first gear ring and a second gear ring which extend towards a rotation center are arranged on the two end faces of the rope winding ring respectively, a guide support is arranged in the shell, the periphery of the guide support is in threaded fit with the rope winding ring, a screw hole is formed in the guide support, a screw is in threaded fit with the screw hole, a first gear is arranged on the screw, the first gear is engaged with the first gear ring, the rope winding mechanism comprises a plurality of sets of overlapped second gears and coil springs, the inner ends of the coil springs are fixed to a positioning shaft, the outer ends of the second gears are fixed to the inner rings of the second gears, and one second gear is meshed with the second gear ring. According to the pulling rope, the length of the rope can be increased on the premise that the overall size of the pulling rope is not increased, and the pulling force of the rope winding mechanism on the rope is more uniform in the rope winding and unwinding process.
Description
technical field [0001] The invention belongs to the technical field of pet leashes, in particular to pet leashes, in particular to pet leashes that can automatically retract the rope. Background technique [0002] With the improvement of people's living standards, more and more families choose to keep pets as family members for daily companionship and playmates for leisure time. Because some pets have a certain aggressiveness, more and more cities require pets to be led by the owner by a leash when they go out. The traction by the leash can not only control the range of activities of the pet but also prevent the pet from getting lost. Existing pet leashes generally include an automatic winding function and a locking function at a certain length of the rope. For example, CN101518211 discloses a leash assembly capable of stretching and locking, which includes: a hollow ring-shaped leash housing; A winding shaft located in the hollow ring-shaped leash casing, which runs throug...
