Abstract
The utility model relates to the field of a vacuum breaker, in particular to a four-bar mechanism of a horizontal vacuum breaker. The four-bar mechanism comprises: a main shaft, an output crank arm, a crank arm plate and a rotating block. The main shaft is arranged on a chassis; one end of the output crank arm is fixed on the main shaft and the other end thereof is connected with a connection plate through a pin; the other end of the connection plate is connected with the crank arm plate through a pin; one corner of the crank arm plate is fixed in a mounting hole of the chassis through a pin shaft; the crank arm plate is connected with the rotating block and the rotating block is provided with a mounting hole; and one end of an operational insulator is arranged in the mounting hole of the rotating block and the other end thereof is connected with a main loop part. The four-bar mechanism is designed according to the transmission characteristics of the horizontal vacuum breaker. When in use, the four-bar mechanism is simple in mounting and compact in structure, improves the transmission stability of the horizontal vacuum breaker, and maintains the primary volume.
Description
Technical field
The utility model relates to the vacuum circuit-breaker technical field, and is concrete, relates to a kind of quadric chain of horizontal assembled type vacuum circuit-breaker.
