[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model provides Figure 1-Figure 4 A multi-terminal connection bus duct shown in FIG. 1 includes a first bus duct body 1 and a second bus duct body 11. The first bus duct body 1 and the second bus duct body 11 are fixedly connected with long strips 5 on both sides of the outer wall close to one end. Two mounting plates 4 are arranged between the first bus duct body 1 and the second bus duct body 11. The mounting plates 4 are located at the outer walls of the first bus duct body 1 and the second bus duct body 11. The mounting plates 4 are concave in shape. A third bus duct body 3 is arranged on one side of the first bus duct body 1. A slot 31 is provided at the bottom of the third bus duct body 3 close to one end of the first bus duct body 1. The corresponding mounting plates 4 are inserted into the interior of the slot 31. When the first bus duct body 1 and the second bus duct body 11 need to be installed, the side plates on the mounting plates 4 are clamped on the two long strips 5 to help fix the first bus duct body 1 and the second bus duct body 11. The mounting plates 4 are concave in shape. The concave-shaped setting is easy to align and fix, which reduces the installation difficulty and error rate, and is convenient and quick to disassemble and assemble, which greatly improves the work efficiency of disassembly and assembly. The concave design of the mounting plate 4 increases the contact area between the mounting plate 4 and the long plate 5, thereby improving the connection density and making the connection tighter and more reliable. At the same time, it can significantly improve the overall strength and stability of the bus duct, ensuring that the equipment or structure can still maintain good performance when subjected to various loads. During normal use, the first bus duct body 1 and the second bus duct body 11 become an integral bus duct. When multi-terminal connection is required, the mounting plate 4 can be used as a connecting plate for multi-terminal connection, so that the third bus duct body 3 can be installed at the expansion end, which is convenient for staff to install the bus duct according to usage requirements. It has strong applicability and is easy to cope with various complex power distribution scenarios. The flexible port design can avoid unnecessary waste and redundancy.

[0028] It should be noted that the first bus duct body 1 and the second bus duct body 11 can be connected to form an integral bus duct through the mounting plate 4, and the mounting plates 4 on both sides can be respectively installed with the third bus duct body 3, so as to facilitate the addition of the third bus duct body 3 according to usage requirements.

[0029] In the present utility model, two through holes 45 are provided in the middle of the long plate of the mounting plate 4, and two second bolts 32 are provided on the top surface of the slot 31. The second bolts 32 pass through the corresponding through holes 45 and are threadedly connected to the third mother trough body 3; the through holes 45 on the mounting plate 4 can connect the first bus trough body 1, the second bus trough body 11 and the other third mother trough bodies 3. When connection is required, the mounting plate 4 is in a vertical state with the first bus trough body 1 and the second bus trough body 11, and the mounting plate 4 is inserted into the slot 31 on the third mother trough body 3, and fixed using the second bolts 32.

[0030] It should be noted that the first bus duct body 1 and the second bus duct body 11 are fixedly connected to each other with a fixing plate 2 at the bottom near one end, and the two fixing plates 2 are staggered up and down. Two first bolts 21 are provided on the fixing plate 2 located on the top surface, and the fixing plate 2 is threadedly connected to the first bolts 21; when installing the first bus duct body 1 and the second bus duct body 11, the fixing plates 2 on the first bus duct body 1 and the second bus duct body 11 are staggered and fitted together up and down, and the fixing plates 2 are fixed with the first bolts 21 to complete the installation.

[0031] It should also be noted that when the third female groove body 3 is fixed to the mounting plate 4 , the bottom plate thereon contacts the fixing plate 2 , thereby making the third female groove body 3 more stable during installation.

[0032] In the present invention, a third threaded rod 53 is threadedly connected to the bottom of the long plate 5, and long holes 43 are opened at the bottom of the side plates on both sides of the mounting plate 4. The third threaded rod 53 is movably connected to the corresponding long holes 43; a nut is installed at the end of the third threaded rod 53. When the mounting plate 4 needs to be fixed, the nut and the third threaded rod 53 can be tightened.

[0033] Furthermore, when it is necessary to unfold the mounting plate 4 to install other third bus trough bodies 3, loosen the nut, pull the mounting plate 4 upward, and the elongated hole 43 on the mounting plate 4 slides upward along the third threaded rod 53 to facilitate its unfolding. After the third threaded rod 53 slides to the bottom of the elongated hole 43, the mounting plate 4 is rotated outward 90 degrees. At this time, it can be used as a connecting plate, and the third threaded rod 53 can be removed from the elongated plate 5. After removal, the mounting plate 4 can be removed from the first bus trough body 1 and the second bus trough body 11. When installation is required, the side plate of the mounting plate 4 is inserted into the side wall of the elongated plate 5, and the third threaded rod 53 is screwed onto the elongated plate 5 while passing through the elongated hole 43. Then, the nut can be installed. When the mounting plate 4 needs to be fixed, tighten the nut. When the nut is loosened, the third threaded rod 53 can slide.

[0034] In the present invention, a cylindrical rod 51 is slidingly provided on the top of the long plate 5, and the two ends of the cylindrical rod 51 are fixedly connected to the limiting disc 52. A spring 54 is fixedly connected to the top of the long plate 5 away from the mounting plate 4, and the end of the spring 54 is fixedly connected to the corresponding limiting disc 52, and the spring 54 is movably sleeved on the cylindrical rod 51; the limiting disc 52 helps to limit the position. When the first bus duct body 1 and the second bus duct body 11 need to be fixed, the limiting disc 52 close to one end is pressed, and the limiting disc 52 drives the cylindrical rod 51 to move, and the cooperation of the limiting disc 52 and the long plate 5 compresses the spring 54.

[0035] It should be noted that a circular hole 41 is provided on the top of the side plates on both sides of the mounting plate 4, and a connecting hole 42 is provided on the top of the circular hole 41. The diameter of the circular hole 41 is larger than the connecting hole 42, and the diameter of the circular hole 41 is the same as the diameter of the limiting disc 52. The cylindrical rod 51 movably connects the circular hole 41 and the connecting hole 42; when installing the mounting plate 4, the limiting discs 52 at one end away from each other pass through the circular hole 41, and the mounting plate 4 slides downward. The cylindrical rod 51 enters the connecting hole 42 along the circular hole 41, and the limiting disc 52 on the other side is released. The spring 54 uses elastic force to restore the limiting disc 52 to its original position, and the limiting disc 52 on the other side is clamped to the outer wall of the side plate of the mounting plate 4 to complete the fixation.

[0036] In the present invention, two openings 44 are provided at the bottom of the long plate of the mounting plate 4; the openings 44 facilitate the rotation of the mounting plate 4. When the mounting plate 4 is rotated to a vertical state, the long strip 5 passes through the openings 44, so that the mounting plate 4 can rotate normally.
