Guide wheel for travel trailer

Abstract

The guide wheel comprises a connecting supporting pipe and a telescopic pipe, a plug pin fixing supporting seat is arranged at the bottom end of the telescopic pipe, and the two side faces of the plug pin fixing supporting seat are rotationally connected with the two ends of a U-shaped plate. A partition plate is arranged in the plug pin fixing and supporting seat and divides the interior of the plug pin fixing and supporting seat into a plug pin moving area and a spring compression area, and the plug pin sequentially penetrates through the plug pin moving area, the spring compression area and the U-shaped plate. The bolt extends to be provided with a deflector rod, the deflector rod is arranged in an inserting groove formed in the upper end face of the bolt fixing and supporting seat, an annular baffle is further arranged on the outer side wall of the bolt arranged in the spring compression area, and the outer side wall of the bolt between the partition plate and the annular baffle is sleeved with a spring. A pressing wheel is further arranged on the inner side of the U-shaped plate, a guide wheel pressing sleeve is arranged at the bottom end of the connecting supporting pipe, and the guide wheel pressing sleeve is arranged over the pressing wheel. When the telescopic pipe moves upwards, the guide wheel pressing sleeve extrudes the shifting rod downwards to enable the plug pin to move leftwards, limiting of the U-shaped plate is relieved, the U-shaped plate is reversely folded, and automatic folding and unfolding of the guide wheel are achieved.
