Description

animal wheelchair

technical field

The utility model relates to an animal wheelchair, in particular to a walking aid wheelchair for physically disabled animals.

Background technique

Many animals such as pet dogs, pet cats, etc. are often unable to move due to the weakness of the waist as they grow older, or they are unable to walk due to limb injuries. These animals cannot walk with their owners because they cannot walk freely, or the lack of walking causes more serious health problems. Therefore, it is very necessary to provide a wheelchair to help disabled animals walk.

The Chinese patent application with the publication number CN2792168Y discloses a car for helping disabled pets to walk. The pet car includes a rectangular frame, the frame is lowered with wheels, the middle of the frame is a soft bottom belt, and the front end of the frame is a front strap. Front pack straps, rear pack straps and handy pockets at the rear of the frame.

The Chinese patent application whose publication number is CN101371809A discloses a kind of walking-assisted wheelchair for disabled pets with hind limbs, including a vehicle frame, a shaft, a cushion, and wheels.
