A kind of bus duct joint anti-rotation bent plate of the present utility model, is arranged between insulated bolt turret head and butterfly gasket.One group of circular hole on base plate is used for installing plural insulated bolt, anti-rotation bent plate left and right sidewall two inner surface and insulated bolt turret head two sides are designed as matched in clearance, prevent insulated bolt from rotating, a spanner is only needed to tighten locking nut during fastening, more can realize fast connecting, improve quality of connection and work efficiency.

A kind of bus duct joint torsional stop of the present utility model, structure and technique are simple, and material can be selected for cold-rolled steel sheet, and by bending and molding, piece surface can use zinc-plated or electrostatic powder coating process, good looking appearance.

As improvement of the present utility model, sidewall and base plate up/down perforation, in C font open design, it is simple to bending and forming, two side width can be designed according to insulated bolt turret head width dimensions, to meet the connection request of different size insulated bolt.

According to this utility model, the circular hole quantity on base plate can be designed according to the quantity of insulated bolt, and with the connection request of satisfied different current specification bus duct joints, preferably 2-6 is individual.
