Abstract
The utility model relates to an inner mechanism of a breaker, in particular to a spring-back resistant device for the breaker. The technical scheme is that the spring-back resistant device is characterized in that a brake of the breaker is separated, if a mating piece fixed on a locking piece is in contact with the upper edge of a limiting hole arranged on a transmission piece, a maximum distance between the lower edge of the locking piece and a backstop is in a range from 2mm to 3mm. By means of the scheme, the spring-back resistant device overcomes a shortage in the prior art and provides a device which can guarantee a reliable spring-back resistant function even though errors of a reset torsional spring parameter are large, and the backstop and the locking piece have multiple collisions with the limiting hole arranged on the transmission piece when the brake of the breaker is separated. The spring-back resistant device adjusts positions of the mating piece downwards, optimizes a shape of the locking piece, adjusts positions of a shaft pin upwards, effectively uses an effect of inertia, and guarantees reliable spring-back resistance under the effect of inertia.
