Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1-4, wherein fig. 1 is a schematic structural diagram of a fixing structure at a turning position of an elbow of an intensive bus duct shell according to the present invention; FIG. 2 is an enlarged view of a portion A of FIG. 1; fig. 3 is a schematic back structure view of a fixing structure at the turning position of the shell elbow of the intensive bus duct provided by the present invention; fig. 4 is a schematic structural view of the triangular support block shown in fig. 1.

Intensive bus duct casing elbow turns to fixed knot of department and constructs, includes:

a first casing 1 and a second casing 2;

the fixing screw 3 is in threaded connection with the edge of the first shell 1;

the fixing plate 4 is sleeved on the outer surface of the fixing screw 3, and the bottom of the fixing plate 4 is respectively contacted with the first shell 1 and the second shell 2;
