Abstract

The present invention relates to an anti-bounce apparatus of automatic transfer switching equipment. The anti-bounce apparatus includes a machine architecture and two anti-bounce mechanisms that are in mirror arrangement. The anti-bounce mechanism includes a spindle, a suspended arm, a pendulum member, a pin shaft, and a reset torsion spring. The suspended arm includes a transmission part and a connection part. The transmission part is connected to a movable contact of the automatic transfer switching equipment. A side board of the machine architecture is provided with a stop matched with the transmission part of the suspended arm. The shape of a cross section of the pendulum member is of a U shape. The front end of the pendulum member is movably sheathed on a connection part of the suspended arm through the pin shaft. The connection part of the suspended arm is provided with a hook-shaped body matched with the front end of the pendulum member. The reset torsion spring is sheathed on the pin shaft. One end of the reset torsion spring is clamped in a U-shaped groove of the pendulum member. The other end of the reset torsion spring is clamped in the hook-shaped body of the connection part of the suspended arm. The reset torsion spring hinges the pendulum member on the connection part of the suspended arm. The tail end of the pendulum member props against the peripheral wall of the spindle. The anti-bounce apparatus has the advantages of simple structure, prominent anti-bounce effect, stable and reliable performance and so on.
