Abstract:
Provided is a multi-mode eccentric wheel anti-panic descender, in order to solve the technical problem that a descender in the prior art cannot achieve both a one-handed operation function and an automatic protection function, and is difficult to operate for a user when used in special occasions such as fire rescues. The multi-mode eccentric wheel anti-panic descender comprises a descender bottom plate, wherein an auxiliary friction wheel and an eccentric braking friction wheel are mounted on the descender bottom plate; the descender bottom plate is provided with a first lock hole; the eccentric braking friction wheel is provided with a limiting sliding groove; the descender bottom plate is fixedly provided with an eccentric wheel limiting shaft which cooperates with the limiting sliding groove; the side of the eccentric wheel limiting shaft close to the auxiliary friction wheel is provided with an eccentric wheel fixing rotating shaft; the braking brake friction wheel can rotate relative to the descender bottom plate via the eccentric wheel fixing rotating shaft; a braking gap is provided between the auxiliary friction wheel and the braking brake friction wheel for a rope to pass through same; and the eccentric braking friction wheel is provided with a state switching component for assisting the descender in switching from a self-locking state to a descending state.
