Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a T-shaped bus duct, lead electrical drainage 2 including T shape shell 1 and T shape, T shape shell 1 includes casing 101 and lower casing 102, the interior table wall of lower casing 102 has recess 7, increase U-shaped pole 5's removal space, the inside of recess 7 is connected with U-shaped pole 5 through telescopic link 3, the outside cover that the T shape led electrical drainage 2 is equipped with insulating cover 6, play insulating effect in the outside of the electrically drainage 2 of T shape, the lateral wall of insulating cover 6 has the spacing hole 601 with U-shaped pole 5 adaptation, the outside four corners of T shape shell 1 all is provided with foot rest 8, be provided with adjusting screw 9 between two adjacent foot rest 8, adjusting screw 9's both ends are run through corresponding foot rest 8 respectively and are connected rather than closing soon through the screw, the distance that drives through adjusting screw 9's rotation between the foot rest 8 changes.

Specifically, as shown in fig. 4, the lower end surface of the upper casing 101 has an integrally formed protrusion 1011, the upper end surface of the lower casing 102 has an integrally formed locking groove 1021, and the protrusion 1011 is engaged with the locking groove 1021, so as to facilitate positioning and locking of the upper casing 101 and the lower casing 102.
