Description

Pet haulage rope with buffering brake mechanism

Technical Field

The invention belongs to the technical field of pet pulling ropes, and particularly relates to a pet pulling rope with a buffering brake mechanism.

Background

With the increasing living standard of people, more and more families choose pets as family members of daily companions and playmates which are enjoyed at leisure. Because some pets have certain aggressiveness, more and more cities require that the pets are pulled by owners through the pulling ropes when going out, and the pulling of the pulling ropes can control the moving range of the pets and prevent the pets from being lost. The existing pet leashes generally include an automatic winding function and a locking function at a certain leash length. For example, CN212065324U discloses a pet leash, which comprises a housing, a first gear, a push button, a base, a latch, an elastic member and a rope; the first gear is arranged in the shell, and the rope is wound on the first gear; the base is arranged on the outer side of the shell and provided with a sliding groove; the push button is arranged in the sliding groove and can slide in the sliding groove; the buckle lock is connected with the elastic piece, is arranged in the shell and is positioned on one side of the base; when the push button slides to a preset first position along the sliding groove, the push button extrudes the buckle lock to enable the buckle lock to lock the first gear; when the push button slides to a preset second position along the sliding groove, the push button releases the buckle, and the buckle is reset by means of the elastic force of the elastic piece to release the first gear. The pet leash controls the locking and unlocking of the first gear through the push button. When the pet is stroked, the first gear is generally in a loose state, and when the pet is stroked, the first gear is generally in a locked state, and because some large dogs have great strength, if the first gear is in the locked state, the momentum generated by sudden running of the large dogs is great, and under the condition of no buffer, the pet is easy to pull down the person at once, and if the pet is stroked, certain danger exists.
