Description of reference numerals:

1. the device comprises support legs, 2, a roller frame, 3, traveling wheels, 4, an automatic support structure, 401, a column sleeve, 402, a column core, 403, springs, 404, a sealing cover, 5 and a bias loading saddle.

Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

It is to be noted that the experimental methods described in the following embodiments are all conventional methods unless otherwise specified, and the reagents and materials, if not otherwise specified, are commercially available; in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

As shown in fig. 1-3, the utility model provides a mobile leg, include:

a support leg 1, which is vertically arranged;

the roller carrier 2 is arranged at the lower part of the supporting leg 1, the roller carrier 2 is in a regular triangle shape, a circular ring is arranged in the roller carrier 2 in the regular triangle shape, the circular ring is fixed with three vertexes of the roller carrier 2 through a connecting rod, and the circular ring is sleeved at the lower part of the supporting leg 1;

and the walking wheels 3 are arranged below three vertexes of the roller frame 2, the joints of the walking wheels 3 and the vertexes are provided with automatic supporting structures 4, the automatic supporting structures 4 contract the walking wheels 3 when the supporting legs 1 bear stress, and the walking wheels 3 stretch out when the supporting legs 1 are unloaded and not stressed.

In the technical scheme, the supporting leg 1 is a main bearing structure; the roller carrier 2 is in a regular triangle shape, and the regular triangle is not easy to deform and has a stable structure; a circular ring is arranged in the roller carrier 2, and the circular ring facilitates the roller carrier 2 to be arranged on the supporting leg 1; the walking wheels 3 are arranged below three vertexes of the roller frame 2 so as to move the supporting legs 1; automatic bearing structure 4 is in shrink when supporting leg 1 bears walking wheel 3 the supporting leg 1 stretches out when empty walking wheel 3 avoids walking wheel 3 is because of influencing supporting leg 1 work and frequent dismouting.
