[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] See also Figure 1-6 The utility model provides a new technical solution: a bus duct, comprising a bus duct body 1 and a bus duct cover 2, wherein the left surface of the bus duct body 1 is provided with two L-shaped chutes 3, and the upper surface of the bus duct body 1 is provided with two clamping holes 4, and the two clamping holes 4 are respectively communicated with the two L-shaped chutes 3;
[0028] Among them, an installation mechanism is provided on the bus duct body 1, which includes two spring slots 6, two first springs 7, two clamping blocks 8, a fixed plate 9, four first slide grooves 10, four second slide grooves 11, four second springs 12, four moving blocks 13 and four fixed sticks 14.
[0029] Furthermore, the busbar duct cover plate 2 is slidably sleeved on the inner surfaces of the two L-shaped sliding grooves 3 , and the two spring grooves 6 are respectively opened on the upper surfaces of the two vertical plates of the busbar duct cover plate 2 .
[0030] Furthermore, the two first springs 7 are fixedly mounted in the inner walls of the two spring slots 6 , respectively. The two clamping blocks 8 are fixedly mounted on the upper ends of the two first springs 7 , respectively. The right surfaces of the two clamping blocks 8 are both inclined.
[0031] Furthermore, the fixed plate 9 is fixedly installed on the lower surface of the bus duct cover plate 2, the four first chutes 10 are all opened on the lower surface of the fixed plate 9, the four second chutes 11 are respectively opened on the rear surface of the fixed plate 9, and the four first chutes 10 are respectively communicated with the four second chutes 11.
[0032] Furthermore, four second springs 12 are respectively fixedly mounted on the inner walls of the four first slide slots 10 , and four moving blocks 13 are respectively fixedly mounted on the opposite ends of the four second springs 12 ;
[0033] The four fixed rods 14 are respectively fixedly mounted on the right surfaces of the four moving blocks 13 , and the four fixed rods 14 are respectively slidably connected to the four second sliding grooves 11 .
[0034] Furthermore, heat dissipation fins 5 are fixedly mounted on the upper surface of the bus duct cover plate 2;
[0035] When the bus duct is in use, the two vertical plates of the bus duct cover 2 are inserted into the two L-shaped slots 3 opened on the two vertical plates of the bus duct body 1. At this time, the inclined surfaces of the two clamping blocks 8 set on the bus duct cover 2 hit the two vertical plates of the bus duct body 1. At this time, the two clamping blocks 8 are forced to shrink, and the two clamping blocks 8 exert pressure on the two first springs 7 fixedly installed on the lower surface to cause them to shrink. At the same time, the two clamping blocks 8 slide into the two spring slots 6. At this time, the two vertical plates of the bus duct cover 2 are continued to be inserted into the two L-shaped slots 3 opened on the two vertical plates of the bus duct body 1. At this time, the two clamping blocks 8 pass through the two clamping holes 4. At this time, the two clamping blocks 8 are no longer under pressure, and the two first springs 7 are no longer under pressure. At this time, the two first springs 7 expand, and the two first springs 7 exert pressure on the two clamping blocks 8 fixedly installed on the upper surface. The second spring 12 expands, and the second spring 12 applies a rightward thrust to the right end fixed movable block 13, so that it is fixed to the right in the first slide groove 10, so that the movable block 13 and the convex block on the lower surface of the fixed plate 9 clamp and fix the cable, completing the cable management process;
[0036] The bus duct can clamp and fix the busbars under the bus duct cover by adjusting the distance between the moving blocks, and perform cable bundling processing on the bus duct, so that the cables in the bus duct are neatly arranged, easy to organize, and convenient for subsequent use. In addition, the bus duct can fix the bus duct cover by engaging the clamping blocks on the bus duct cover with the clamping holes on the bus duct body. Compared with the driven bus duct that only slides in the bus duct body and lacks a limiting structure, the device can position the bus duct cover, which is convenient for subsequent fixed installation.
[0037] Working principle: When the bus duct is in use, the two vertical plates of the bus duct cover 2 are inserted into the two L-shaped slide grooves 3 opened on the two vertical plates of the bus duct body 1. At this time, the inclined surfaces of the two clamping blocks 8 set on the bus duct cover 2 hit the two vertical plates of the bus duct body 1. At this time, the two clamping blocks 8 are forced to shrink, and the two clamping blocks 8 exert pressure on the two first springs 7 fixedly installed on the lower surface to cause them to shrink. At the same time, the two clamping blocks 8 slide into the two spring grooves 6. At this time, the two vertical plates of the bus duct cover 2 are continued to be inserted into the two L-shaped slide grooves 3 opened on the two vertical plates of the bus duct body 1. At this time, the two clamping blocks 8 pass through the two clamping holes 4. At this time, the two clamping blocks 8 are no longer under pressure, and the two first springs 7 are no longer under pressure. At this time, the two first springs 7 expand, and the two first springs 7 exert pressure on the two clamping blocks 8 fixedly installed on the upper surface. The second spring 12 expands, and the second spring 12 applies a rightward thrust to the right end fixed movable block 13, so that it is fixed to the right in the first slide groove 10, so that the movable block 13 and the convex block on the lower surface of the fixed plate 9 clamp and fix the cable, completing the cable management process.
