Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the utility model provides a miniature impact-resistant caster, which comprises a main support 1, a rotating assembly 2 for supporting external equipment and a roller 7 arranged on the main support 1, wherein the main support 1 is provided with a support table 11 for installing the rotating assembly 2, the upper end and the lower end of the support table 11 are both provided with the rotating assembly 2, and the rotating assembly 2 is arranged on the support table 11 through a rotating connecting piece 3;

referring to fig. 3, 4 and 5, the rotating assembly 2 includes a rolling member 21 and a mounting shell 22 for mounting the rolling member 21, the rolling member 21 is disposed between the mounting shell 22 and the supporting base 11, and the mounting shell 22 is provided with a rolling groove 221 adapted to the rolling member 21. Therefore, the thickness of the rotating assembly 2 is basically determined by the size of the rolling member 21 and the thickness of the mounting case 22, so that compared with a structure adopting a spring or the like as an impact resistance, the whole height of the utility model is lower, and the transportation stability is higher.

Specifically, the supporting platform 11 is provided with a through hole 111 for the rotation connecting piece 3 to pass through, the installation shell 22 is provided with a shaft hole 222 adapted to the rotation connecting piece 3, and the rotation connecting piece 3 passes through the through hole 111 and the shaft hole 222 so as to connect the installation shell 22 to the supporting platform 11.
