Detailed Description

For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.

As shown in fig. 1 to 4, a combined multi-stage bus duct structure includes a main housing 1, two bus duct main bodies 2 arranged in parallel are arranged inside the main housing 1, and the two bus duct main bodies 2 are connected through a plurality of adjusting mechanisms 3; bus duct main part 2 include bus duct casing 21 and be located the inside a plurality of copper bar 22 of bus duct casing 21, link to each other through the spliced pole between a plurality of copper bar 22, the both ends of spliced pole link to each other with bus duct casing 21.

The bottom of bus duct casing 21 is equipped with base 6, base 6 on the symmetry be equipped with two side connecting rods 7, the head of side connecting rod 7 is articulated mutually, the afterbody of side connecting rod 7 even has pulley 8, 8 butt of pulley on main casing body 1's inner wall, pulley 8's tip is equipped with the polyurethane cushion, the middle part of two side connecting rods 7 links to each other through first spring.

The adjusting mechanism 3 comprises a main shaft 31, a clearance groove is formed in the middle of the main shaft 31, the bottom end of the main shaft 31 penetrates through the main shell 1 and is connected with a nut, a four-bar mechanism composed of four main connecting rods 32 is arranged on the main shaft 31, and the middle portions of the four-bar mechanism are connected through a second spring 33.
