Description

Technical Field

[0001] The utility model relates to the technical field of pet appliances, in particular to a pet traction rope that can be unlocked in an emergency. Background Art

[0002] A pet is a living creature kept for spiritual, rather than financial, purposes. Keeping pets provides an opportunity for humans to connect with nature, fulfilling psychological needs and making it a healthy and normal hobby. While pets come in a wide variety of types, dogs are the most popular household pet.

[0003] After raising a pet dog, taking it for a walk becomes a daily necessity for every owner, and when walking the dog, the dog needs to be tied with a leash. When the owner takes the elevator with the pet dog, because the pet dog is naughty, it will run in or out of the elevator before the owner. If the owner does not follow in time and the elevator door closes, the pet and the owner will be separated by the elevator door inside and outside. In this case, the traditional pet leash cannot be unlocked and detached from the pet collar, nor can it trigger the elevator door's anti-pinch mechanism. As a result, after the elevator starts, the elevator door pinches the leash when rising or descending, and the leash tightens, strangling the pet dog, causing a tragedy. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art and provide a pet leash that can be urgently unlocked. When the pet and the owner are separated inside and outside the elevator car by the elevator door, the leash can be urgently unlocked and separated from the pet collar to ensure the safety of the pet.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is as follows:

[0006] A pet leash with emergency unlocking capability comprises a buckle, a loop, a rope, a cylindrical latch, and a clamping and locking rod, one end of the rope being connected to the loop. The buckle base of the buckle and the loop base of the loop are each provided with a pin hole A for the cylindrical latch to pass through, and a retaining ring having a diameter greater than that of the pin hole A is provided at the lower end of the cylindrical latch. The side and bottom surfaces of the loop base are provided with openings communicating with the pin hole A. The clamping and locking rod is L-shaped, with an eccentric cam at its lower end. The eccentric cam is located within the opening, and corresponding pin holes B are provided on either side of the eccentric cam and the opening, respectively. A connecting pin is provided within pin hole B. The buckle is equipped with a spring switch and is connected to the pet collar when the dog is walking. The cylindrical latch passes through the pin holes A of the buckle base and the loop base from bottom to top and can rotate freely within the buckle base. Under normal circumstances, the eccentric cam compresses the cylindrical latch through friction, preventing it from disengaging. In an emergency, such as when the pet and owner are separated by the elevator door, the owner pulls the rope, the compression lock rod contacts the elevator door, and is forced outward to open. The eccentric cam and the cylindrical latch are unlocked, and the cylindrical latch is released and can be detached from the hanging ring, remaining on the pet collar together with the hook, ensuring the safety of the pet. It is important to note that even if the owner does not pull the rope in time, the upward or downward movement of the elevator will tighten the rope until the compression lock rod is acted upon by external force, and it can also be unlocked and separated from the pet collar.

[0007] Preferably, the upper end of the clamping and locking rod is provided with an inclined surface to play a guiding role, ensuring that the clamping and locking rod can be flipped outward to be unlocked after being subjected to force in contact with the elevator door.

[0008] Preferably, a retaining spring groove is provided in the middle of the cylindrical pin, and a retaining spring is provided in the retaining spring groove, so that the cylindrical pin cannot be detached from the hook base.

[0009] Preferably, the upper surface of the cylindrical latch is provided with a rough surface to increase friction and prevent the cylindrical latch from sliding out in the locked state.

[0010] Preferably, a concave ring is provided on the upper surface of the cylindrical latch, and the end of the eccentric cam is located in the concave ring in the locked state, which serves to limit the position and prevent it from disengaging.

[0011] The advantage of the utility model is that when the pet and the owner are separated inside and outside the elevator car by the elevator door, the pet leash can be urgently unlocked and separated from the pet collar to ensure the safety of the pet. BRIEF DESCRIPTION OF THE DRAWINGS
