Abstract

A universal wheel with a plastic wheel fork comprises the plastic wheel fork, two wheel fork bearings, a round head bolt, a nut, a lock bolt and a PU (polyurethane) wheel with two bearings at the hole center. The universal wheel is characterized in that two counter bored holes are arranged above and below the top of the plastic wheel fork respectively, a through hole is arranged between the upper counter bored hole and the lower counter bored hole of the plastic wheel fork, mutually-communicated holes are arranged on two wheel forks at the lower end of the plastic wheel fork, a wheel fork bearing is embedded in each of the upper counter bored hole and the lower counter bored hole of the plastic wheel fork respectively, the round head bolt penetrates into inner holes of the two wheel fork bearings, the nut is screwed on the round head bolt penetrating into the inner holes of the two wheel fork bearings, the lock bolt comprises a screw cylinder and a bolt, and the screw cylinder penetrates into the mutually-communicated holes and two inner holes of bearings of the PU wheel to be screwed with the bolt. The universal wheel with the plastic wheel fork after assembly can use a screw rod screwed on the round head bolt in two wheel fork bearing holes at the top of the plastic wheel fork to be connected with a recreational vehicle.

Description

technical field [0001] The invention relates to a universal wheel for an amusement vehicle, in particular to a universal wheel for a plastic wheel fork made of plastic. technical background [0002] At present, the wheel forks of the universal wheels for recreational vehicles that can be seen on the market are generally metal (or iron or aluminum), which brings certain restrictions, or the shape is not enough.
