Description

Double-circuit power supply safety self-locking device

Technical field

The utility model relates to electrical equipment technical field, specially a kind of double-circuit power supply safety self-locking device.

Background technique

In pharmaceutical production, some, which belong to, works continuously, and centre cannot pause, thus needs transformer there are two settings, In use, if there is powering off all the way, then needing to carry out the replacement of two transformers immediately.Or it as needed, needs It is replaced between two transformers, in the actual operation process, it sometimes appear that two transformers have electricity, a connection is just in work Make, and another transformer is also pushed to work by operator's maloperation, this results in two transformers and interferes with each other, and causes safety Accident.

Utility model content

The technical problem to be solved by the utility model is in view of the deficiencies of the prior art, providing a kind of double-circuit confession Electric foolproof apparatus solves existing pharmaceutical factory and easily occur because maloperation causes two when replacement uses to two transformers The problem of transformer accesses simultaneously.

The technical solution of the utility model is:

A kind of double-circuit power supply safety self-locking device, the electric pole being used to support including four, on four electric poles Be fixedly connected with a placement platform, the left and right sides at the top of the placement platform be removably connected with respectively the first transformer and Second transformer, the front positioned at positive two electric poles has been bolted to connection fixed iron block, described solid The side for determining iron block is welded with fixed disk, and the side of the fixed disk is threaded with gag lever post, is socketed on the gag lever post Hand lever and adjustment disk, the adjustment disk are welded on the hand lever, and the side of the adjustment disk side surface is interspersed with motion bar, described One end of motion bar is welded with pull rod, and the two sides up and down of the fixed disk side surface are welded with the first snap ring, the hand lever Side is welded with the second snap ring, and the top of positive two electric pole opposite sides is fixedly connected by connecting plate, the company The positive left and right sides of fishplate bar passes through two lantern rings and is connected with bull stick, and the top of the pull rod is welded with inserted link, described Inserted link is socketed with link block, top of the link block far from the inserted link side and the one of the bull stick far from one end of pull rod End welding, the other end of the bull stick are fixedly connected with terminal plate, are fixedly connected at left and right sides of the connecting plate bottom Insulate fishplate bar, and two insulation fishplate bars pass through electric wire and connect respectively with the first transformer and the second transformer electric wire.

Preferably, there are two the lantern rings, the lantern ring to be welded on the front of the connecting plate for socket on the bull stick.Institute Stating terminal plate includes adjustable plate, collets there are two sockets on the adjustable plate, fixed respectively on two collets to connect It is connected to zero curve contact block and firewire contact block.
