Summary of the invention
The purpose of this utility model is to be to overcome above-mentioned shortcoming and a kind of withdraw-type switch cabinet valve blocking mechanism is provided, and it is simple in structure, and safe and reliable.
For achieving the above object, withdraw-type switch cabinet valve blocking mechanism of the present utility model comprises pedestal, the last valve connecting plate that is used for being connected with last valve is installed on the pedestal, is used for the following valve connecting plate that is connected with following valve, last valve connecting plate and following valve connecting plate are provided with horizontal rotating shaft, and last valve connecting plate and following valve connecting plate can rotate around horizontal rotating shaft; Last valve connecting plate and following valve connecting plate also are respectively equipped with lockhole; Upper lock plate, lower locking plate, pressing plate also are installed on pedestal, and pressing plate exposes the pedestal side, and upper lock plate, lower locking plate, pressing plate three are connected to one, and upper lock plate and lower locking plate are provided with vertical rotating shaft, and upper lock plate and lower locking plate can rotate around vertical rotating shaft; Upper lock plate and lower locking plate also are respectively equipped with the lock pawl, the lockhole position correspondence of the lock pawl of upper lock plate and last valve connecting plate, the lockhole position correspondence of the lock pawl of lower locking plate and following valve connecting plate; Between upper lock plate, lower locking plate and pedestal, be provided with torsion spring.
Be preferably, connecting plate in the middle of being provided with between upper lock plate and the lower locking plate, upper lock plate, lower locking plate and middle connecting plate are integrally formed, middle connecting plate and pressing plate riveted joint, described torsion spring is arranged between middle connecting plate and the pedestal.Like this, because upper lock plate, lower locking plate and middle connecting plate form one,, also just be equivalent to be arranged between lower locking plate and the pedestal so torsion spring is arranged between middle connecting plate and the pedestal.
The utlity model has following advantage and effect:
1, be advanced to the service position from test position when circuit breaker, the utility model can make valve, valve is in opening flexibly down; When circuit breaker is advanced to test position from the service position; the utility model can make valve, valve automatically locks down; avoid maintenance, testing crew malfunction valve mechanism and touched charged fixed contact, protected the personal safety of maintenance, testing crew better, reached the requirement of regulation and stipulation.
2, the utility model structure is practical reliable, simply attractive in appearance.
