A kind of walking aid front caster wheel assembly, comprise forelimb pipe and castor, the forelimb pipe is skewed extension setting, be connected with wheel fork on the castor, it is characterized in that, described forelimb pipe bottom is fixedly connected with universal axle sleeve, universal axle sleeve is by preceding, rear casing is formed, forelimb pipe bottom sleeve is gone in the rear casing, on the preceding pipe box, the lower surface be covered with respectively the band through hole on, following universal axle sleeve plug, before one screw interts in the pipe box on it, on extend the lower end, down universal axle sleeve extends down that the screw of universal axle sleeve plug is connected with wheel fork locking beyond the Great Wall, described on, universal axle sleeve plug end face is respectively arranged with and the opposite inclined end face of forelimb pipe incline direction down.Adopt the walking aid front caster wheel assembly of this structure, because upper and lower universal axle sleeve plug end face is respectively arranged with and the opposite inclined end face of forelimb pipe incline direction, not only make castor and ground reach parallel, and upper and lower universal axle sleeve plug is same shape and structure, just be separately positioned on the preceding upper and lower end face of pipe box, be that upper and lower universal axle sleeve plug can be manufactured out by same mould, effectively reduce production costs, install easy to connect.
Described rear casing becomes pipe box one side before skewed being connected in, and forelimb pipe sleeve is gone into the rear casing inner chamber by the blind rivet connection of riveting tightly, and constitutes acute angle between the central axis of forward and backward pipe box.
Described screw intert into before in the pipe box its upper and lower end extend upper and lower universal axle sleeve beyond the Great Wall, connect by nut on the screw of corresponding upper and lower universal axle sleeve plug end face, extending down, the screw end of universal axle sleeve plug passes the wheel fork end face and connects by nut.
Described universal axle sleeve or following universal axle sleeve plug are made up of lid and the sleeve that is connected the lid below respectively, the upper and lower end face opening of preceding pipe box has cushion cap, the cushion cap both sides are provided with limited impression, and the sleeve both sides of corresponding lid bottom surface are provided with and are respectively equipped with the spacing block set that can peg graft in the limited impression.
Have slanted angle between the vertical wheel line of described forelimb tubular axis line and castor, corresponding upper and lower universal axle sleeve plug end face is respectively arranged with and the opposite inclined end face of forelimb pipe slanted angle direction.
The beneficial effects of the utility model are:
A kind of walking aid front caster wheel assembly of the present utility model, because upper and lower universal axle sleeve plug end face is respectively arranged with and the opposite inclined end face of forelimb pipe incline direction, not only make castor and ground reach parallel, and upper and lower universal axle sleeve plug is same shape and structure, just be separately positioned on the preceding upper and lower end face of pipe box, be that upper and lower universal axle sleeve plug can be manufactured out by same mould, effectively reduce production costs, install easy to connect.
