More Information
Summary:The invention discloses a self-hold brake device. The device comprises a shell; one side of the shell is opened; a cover plate for covering the opening is mounted in the opening; a rotating shaft cavity and a slide base cavity for communicating with each other are formed in the shell; a rotating shaft out of the shell is inserted in the rotating shaft cavity, and can freely rotate in the rotating shaft cavity; the slide base cavity communicates to the opening of the shell; a slide base capable of sliding in the slide base cavity is arranged in the slide base cavity; and spring cavities are respectively formed in two sides of the slide base. The self-hold brake device is respectively provided with the spring cavities, with springs inside, on two sides of the slide base; when a cam rotates to enable a projection part thereof to not butt again a cam groove, under the effect of elastic force of the springs in the spring cavities, a projection on a slide tongue of the slide base is contacted with the rotating shaf
