Description

Pet haulage rope

Technical Field

The invention belongs to the technical field of pet pulling ropes, and particularly relates to a pet pulling rope, in particular to a pet pulling rope capable of automatically retracting a rope.

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 leash generally comprises an automatic rolling function and a locking function at a certain leash outlet length, for example, CN101518211 discloses a leash assembly capable of stretching and locking, which comprises: a hollow annular lead housing; a spool located within the hollow annular lead housing and extending through the circumference of the hollow annular lead housing; a length of rope having one end connected to the spool inside the hollow annular draft gear housing and extending from a rope opening provided on the surface of the hollow annular draft gear housing and the other end outside the hollow annular draft gear housing; a retraction device within the hollow annular lead housing, the retraction device exerting a force to retract the cord around the spool into the hollow annular lead housing; and a brake trigger accessible by a user, said trigger having at least one braking position and a free position; and a portion of the hollow annular leash housing distal from the leash opening and retraction means forms a handle, wherein the retraction means comprises a pair of leash housing halves and. The handle portion of the device is provided with a pair of rubber or rubber-like soft gripping halves. The gear housing and the belt housing halves are integrally formed and provide a generally cylindrical space with a spring shaft. The spur gear has an outer gear rim and a central opening on a shaft that fits within the gear housing. A coil spring is mounted within the spur gear, and a coil spring cover is assembled with and receives the coil spring within the spur gear. When the spur gear rotates around the shaft and applies a recoil torque, the coil spring elastically deforms to restore the spur gear to the original direction. The entire retraction device is assembled together by six screws. This kind of pet haulage rope is including automatic rolling function and at the locking function of certain play rope length, but because the space in the annular tractive belt casing is limited, the space of coil spring installation receives the restriction, and the coil spring volume is limited, and it is limited to lead to the number of turns that the coil spring can rotate the energy storage along with the gear, and the number of turns of rotation of spool receives the restriction, only can rotate several rings, consequently leads to the restriction that the length of rope received, and the rope can not the overlength. The length of rope just can be prolonged to the size that must enlarge whole area tractive subassembly, this weight and the volume that leads to whole area tractive subassembly are showing and is increasing, and it is inconvenient to use, and the moment of exporting by the coil spring when tightening is big moreover, and when being close relaxing entirely, the moment of export can reduce a lot, leads to the coil spring to the pulling force of rope inhomogeneous, and required pulling force is too big when the afterbody will pull out the rope.
