Problems solved by technology
[0002] Most of the bottoms of medical equipment, fitness equipment and other equipment are equipped with easy-to-move casters. The existing casters, whether they are universal wheels or non-universal wheels, are fixed, and their axles are fixedly installed at the bottom of the equipment. On the mounting base, when the device is in a static state, since the bottom is equipped with casters, it can still slide when subjected to a slight external force, which may affect the normal use of the device

The invention discloses an electric type wheel-change supporting leg. The electric type wheel-change supporting leg comprises a round shell foot plate, a trundle bracket, trundle vertical grooves, a roller wheel and a roller shaft; the roller shaft can slide up and down in the trundle vertical grooves, and the upper end of the trundle bracket is connected with the round shell foot plate, and a trundle transverse groove is formed in the trundle bracket and a sliding block is arranged on the trundle bracket; the sliding block, a nut, a screw rod and a motor make up a micro electric push rod; themicro electric push rod is controlled to stretch out and draw back, so that the sliding block slides horizontally in the trundle transverse groove, and the roller shaft is locked or released to slidein the trundle vertical groove; the round shell foot plate and the trundle bracket can be lifted under the action of external force, and the roller wheel shaft can slide in the trundle vertical groove during lifting; when the round shell foot plate is separated from the ground, if the state of the locked roller shaft is released, the roller wheel is hidden in the wheel-change supporting leg whichis supported on the ground through a plane of the supporting leg; and when the roller shaft is locked through operating the micro electric push rod to stretch out and draw back, the roller wheel protrudes out of the wheel-change supporting leg which is supported on the ground through the roller wheel and can roll. The electric type wheel-change supporting leg has the advantages of being novel instructure, easy and convenient to install, easy to operate and the like.
Description
technical field [0001] The invention relates to movable casters for electric wheelchairs, medical equipment, fitness equipment, etc., in particular to an electric wheel-changing foot with the casters hidden in the foot plate. Background technique [0002] Most of the bottoms of medical equipment, fitness equipment and other equipment are equipped with easy-to-move casters. The existing casters, whether they are universal wheels or non-universal wheels, are fixed, and their axles are fixedly installed at the bottom of the equipment. On the mounting base, when the device is in a static state, since the bottom is equipped with casters, it can still slide when subjected to a slight external force, which may affect the normal use of the device. Contents of the invention [0003] The present invention aims to solve the above problems, and provides an electric wheel-changing foot, so that when the foot plate is lifted, the wheel-changing foot can be electrically controlled so tha...
