Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, a brake wheel mechanism includes a rotary head 1 coaxially disposed with a wheel, a brake pad 2 disposed in the rotary head 1 and capable of sliding up and down, and a brake spindle assembly 3, the brake spindle assembly 3 pressing the brake pad 2 through the rotary head 1 and putting the rotary head 1 and the wheel in a stationary state. The wheel, the rotating head 1 and the brake pad 2 are connected together through the same wheel nail 14; the brake pad 2 is fixed in the rotating head 1.
The brake shaft component 3 comprises a pressure lever 31, a buffer spring component 32 and a brake shaft 33; the damper spring assembly 32 includes a damper spring cover 321, a damper spring 322, and a damper spring cover 323. The device also comprises a rotating shaft 4, wherein the rotating shaft 4 is vertically arranged in the rotating head 1, and a brake shaft 33 is arranged in the rotating shaft 4 in a penetrating way and moves up and down in the rotating shaft 4.
The lower end of the pressure lever 31 is fixed in the pressure lever fixing hole 5 at the upper end of the buffer spring cover 321; the damper spring 322 is provided inside the damper spring cover 323 and has an upper end connected to the damper spring cover 321.
