Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals.

It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

With reference to the accompanying drawings 1-3, the utility model provides a technical scheme: a damping type mute caster comprises a roller 1, wherein a rolling shaft 2 is arranged in the middle of the roller 1, two ends of the rolling shaft 2 are respectively and fixedly connected with two fixed columns 3, a supporting frame 4 is arranged above the roller 1, and the upper ends of the two fixed columns 3 are fixedly connected to two sides of the supporting frame 4; the fixed multiunit that is equipped with in bottom surface under support frame 4

inhales sound pad

5, 4 up end fixedly connected with cylinders on the support frame rotate post 6, the cylinder rotates 6 tops of post and rotates to connect and be equipped with cuboid rotor plate 7, the fixed cylinder damping device 8 that is equipped with on the rotor plate 7.

Damping device 8 comprises buffer block 9, buffing pad 10, reference column 11, dashpot 12 and spring 13, buffer block 9 sliding connection buffing pad 10, buffing pad 10 is inside to be equipped with a plurality of reference columns 11, be equipped with a plurality of dashpots 12 with reference column 11 matched with on the buffing pad 9, be equipped with spring 13 between dashpot 12 and the reference column 11, spring 13 is around establishing on reference column 11.

A first screw 14 is fixedly connected above the buffer seat 10 and used for fixedly connecting the caster.
