SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an isolator operation turning arm, the angle of this operation turning arm can freely be adjusted and need not to bore repeatedly, the effectual work efficiency that has improved.

The utility model discloses a following technical scheme realizes:

the utility model provides an isolator operation connecting lever, includes base and support, the base is provided with a plurality of partition modulus hole A, the support be provided with a plurality of with partition modulus hole A assorted partition modulus hole B, the support with the base passes through partition modulus hole A with partition modulus hole B connects.

In the scheme, the operation connecting lever is arranged in a split mode, during installation, the base is firstly fixed on an operation rotating shaft of the isolating switch, then bolts sequentially penetrate through the equal modulus holes A and the equal modulus holes B, and nuts are fixed on the bolts, so that the support and the base are fixed. And if the angle of the operating crank arm is not proper, dismounting the bolt and the nut, adjusting the angle between the bracket and the base by rotating the bracket, and fixing the bracket and the base by using the bolt and the nut.

Furthermore, the base is further provided with a fixing through hole A and a fixing through hole B, the fixing through hole A is used for fixing the base on the upper rotating shaft of the isolating switch, the fixing through hole A is arranged at the bottom of the base, and the inner wall of the fixing through hole A is radially provided with the fixing through hole B.

When the isolating switch is installed on the same type of operation cabinet, the base is fixed on the operation rotating shaft, the positions of the base on the operation rotating shaft are consistent, and the installation position of the base can be positioned by arranging the fixing through hole B. During installation, the fixing through hole A is firstly sleeved on the operation rotating shaft of the isolating switch, then a drill bit is used for drilling holes in the operation rotating shaft at the position of the fixing through hole B, and the pin is clamped.

Further, the base includes upper base and lower base, fixed through hole A set up in the bottom of upper base, lower base set up in the side of upper base bottom, divide the modulus hole A set up in the bottom of lower base.

Furthermore, the upper base is cylindrical, the lower base is annular, the lower base is sleeved at the bottom of the upper base, and the equal-fraction holes A are formed in the lower base along the circumferential direction. The arc-shaped structure is convenient for adjusting the angle of the operating crank arm.

Further, the support includes support A and support B, support A's one end is provided with the connecting hole that is used for being connected with JS operating mechanism, support A's the other end with support B's side fixed connection, divide module hole B etc. set up in support B's bottom.

Furthermore, the bracket B is annular, and the equal modulus holes B are arranged on the bracket B along the circumferential direction.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

the operation connecting lever is arranged to be split, the angle of the operation connecting lever can be freely adjusted through the bolt without repeated drilling, and the working efficiency is effectively improved.
