Description

The wheelchair auxiliary wheel

Technical field

This utility model relates to a kind of wheelchair, particularly a kind of Convenient wheelchair auxiliary wheel of taking action in small space.

Background technology

At present the front-wheel on the wheelchair is steamboat, and trailing wheel is bull wheel, and by certain space length the time, the key factor that limits its action is the size of trailing wheel and the width between two trailing wheels.Therefore, the inconvenient problem that wheelchair need be when small space uses is not all considered in the design of a lot of wheelchairs, such as: escalator.

The utility model content

The utility model purpose: at the problems referred to above, the purpose of this utility model provides the auxiliary wheel that a kind of Convenient wheelchair can normally pass through in small space.

Technical scheme: a kind of wheelchair auxiliary wheel, comprise holder, mount pad, steamboat, described mount pad one end is the loop bar of hollow, the described mount pad other end is U-shaped prong, described steamboat is installed in the described U-shaped prong, described holder one end inserts described loop bar and fixes, and the described holder other end is connected wheelchair trailing wheel place.

Offer one group of locating hole that height and position is different on the described holder.

Beneficial effect: compared with prior art, the utility model has the advantages that when wheelchair small space by the time, remove original bigger trailing wheel, small and exquisite auxiliary wheel is installed simple in structure so that wheelchair normally takes action, be convenient to dismounting and adjusting.
