Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct with stable connection. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute large power to various components of the dispersed system. It has increasingly replaced wires and cables in outdoor low-voltage power transmission trunk line projects.

[0003] The utility model patent application document with the announcement number "CN219918336U" discloses a bus duct with efficient and stable connection, which is mainly composed of a bus duct body and a connecting mechanism. This technical solution makes the connection between the two bus duct bodies more stable by installing a connecting mechanism between two adjacent bus duct bodies, which can effectively avoid the occurrence of safety accidents caused by the shaking of the bus duct body. The design of the tight connection between the limit rod and the limit plate on the connecting mechanism and the first fixed groove and the second fixed groove opened on the bus duct body improves the sealing performance of the connection between the two bus duct bodies, and avoids the situation that dust enters the interior of the bus duct body, thereby causing excessive dust accumulation for a long time to damage the internal circuit and affect the use.

[0004] The bus duct with efficient and stable connection disclosed in the above document has the following defects: when the connecting mechanism of the bus duct is in use, the corresponding positioning plate needs to be plugged and fixed to the positioning slot, but after being plugged and unplugged from the inside of the positioning slot for a long time and many times, it is easy to cause wear on the side surface of the positioning plate and the inner wall of the positioning slot, which in turn causes looseness between the positioning plate and the positioning slot, causing the connecting mechanism to lose its function.

[0005] It can be seen from this that the existing bus duct with efficient and stable connection does not have a good connection structure, and it is necessary to improve the existing deficiencies and provide a bus duct with stable connection. Utility Model Content

[0027] See also Figure 1 - Figure 5 As shown, the utility model is a bus duct with stable connection, including a bus duct body 1 and a connection structure 2. The outer surface of the bus duct body 1 is provided with a mounting plate 101, and a connection structure 2 is arranged between every two adjacent mounting plates 101. The connection structure 2 includes a shell 201, a protection block 202, a connecting rod 203, a first connecting block 204, a second connecting block 205, an anti-dropping block 206 and a mounting block 207. The shell 201 is fixed into two and symmetrically arranged. The outer surfaces of the two shells 201 are provided with mounting blocks 207, and the outer surface of one of the shells 201 is provided with a first connecting block 204. A second connecting block 205 is provided on the outer surface of the other shell 201. The second connecting block 205 is fixed in two and symmetrically arranged. A first connecting block 204 is arranged between the two second connecting blocks 205. Through holes are provided in the middle of the first connecting block 204 and the second connecting block 205. A connecting rod 203 is rotatably connected inside the through hole. External threads are provided at both ends of the connecting rod 203. The connecting rod 203 is threadedly connected to the anti-slip block 206 through the external threads. Protective blocks 202 are installed inside the two shells 201, and the outer surfaces of the protective blocks 202 are in contact with the outer surface of the bus duct body 1.

[0028] A sealing groove 20101 is formed at one end of one of the shells 201 , and a sealing block 20102 is formed at one end of the other shell 201 . The sealing block 20102 is installed in the sealing groove 20101 .

[0029] A limiting groove 20103 is provided on the inner surface of the shell 201 , a limiting block 20201 is provided on the outer surface of the protection block 202 , and the limiting block 20201 is installed in the limiting groove 20103 .

[0030] A mounting hole is provided in the middle of the mounting block 207, and a fixing structure 3 is installed inside the mounting hole.

[0031] The fixed structure 3 includes a slider 301, a slide plate 302, a spring 303 and an abutment block 304. The slider 301 is slidably connected to the inside of the mounting hole. A chamber is provided inside the slider 301. The slider 302 is slidably connected to the inside of the chamber. The slide plates 302 are fixed in two and are symmetrically arranged. A spring 303 is installed between the two slide plates 302. Through openings are provided at both ends of the slider 301. One end of the through opening extends to the inside of the chamber. Abutment blocks 304 are installed at one end of the two slide plates 302. The abutment blocks 304 are slidably connected to the inside of the through opening. The outer surface of the abutment blocks 304 abuts against the outer surface of the mounting block 207.

[0032] The outer surface of the protection block 202 is coated with a high temperature resistant coating.

[0033] When in use, first install the two bus duct bodies 1, and then place the shell 201 on the installation plate 101. After placing it, squeeze the installation block 207 inward to close the two shells 201, and at the same time, make the sealing block 20102 cooperate and install it in the inside of the sealing groove 20101. The outer surface of the protective block 202 abuts and fixes the outer surface of the bus duct body 1. After the two shells are closed 201, pick up the slider 301, and then squeeze the abutment block 304 so that the abutment block 304 pushes the slide plate 302 to move inside the chamber. At the same time, the spring 303 gradually contracts. When the abutment block 304 is flush with the outer surface of the slider 301, place the slider 301 at the installation hole, and then push the slider 301 to install it. After the slider 301 is installed, the spring 303 restores its elasticity to push the slide plate 302 to reset, and the slide plate 302 pushes the abutment block 30 4 moves toward the outside of the chamber so that the abutting block 304 abuts against the outer surface of the mounting block 207 for fixation. When one of the shells 201 is damaged, the abutting block 304 is squeezed so that the abutting block 304 pushes the slide plate 302 to move toward the inside of the chamber, and the spring 303 gradually contracts. When the abutting block 304 is flush with the outer surface of the slider 301, the slider 301 is pulled outward at this time so that the slider 301 is disengaged from the inside of the mounting hole, so that the two shells 201 are cancelled from being fixed, and then the shell 201 can be removed from the bus duct body 1, and the anti-detachment block 206 is rotated counterclockwise so that the anti-detachment block 206 and the connecting rod 203 are cancelled from being fixed. After the anti-detachment block 206 is cancelled, the connecting rod 203 can be pulled outward so that the two shells 201 are cancelled from being hinged, and then the damaged shell 201 can be replaced.
