[0002] The busbars inside the distribution box are energized when the equipment is running. When operators open the distribution box, they may accidentally touch the exposed copper busbars, which could lead to electric shock accidents.

[0003] Therefore, manufacturers often seal the busbar surface with acrylic glass to form a barrier. The conventional way to fix the acrylic glass is to install a fixed bracket around it and fix the acrylic glass on it. When maintenance personnel need to remove the acrylic glass, the work is very cumbersome.

[0004] Therefore, we propose a protective cover for the copper busbars of the incoming line branches in the distribution box. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This embodiment is a protective cover for the copper busbars of the incoming line branch in the distribution box with a plastic shell.

[0025] like Figure 1-4 As shown, the device includes a first fixed bracket 1, a second fixed bracket 2, and an acrylic plate 3. Ear plates 7 are fixedly installed on one side of the lower outer surface of both the first fixed bracket 1 and the second fixed bracket 2. A first mounting strip 4 is fixedly installed on the outer surface of the acrylic plate 3 near the first fixed bracket 1, and a second mounting strip 5 is fixedly installed on the outer surface of the acrylic plate 3 near the second fixed bracket 2. A hinge 6 is provided between the first mounting strip 4 and the first fixed bracket 1. A snap-fit ​​assembly 8 is installed in the middle of the upper outer surface of the second fixed bracket 2. A limit strip 9 is fixedly installed on the lower part of one side of the outer surface of the second fixed bracket 2. The snap-fit ​​assembly 8 includes a concave cover 10, a baffle 11, a movable block 12, an upper inclined wedge block 13, a guide hole 14, a guide rod 15, and a coil spring 16. The concave cover 10 is fixedly installed in the middle of the upper outer surface of the second fixed bracket 2.

[0026] The left and right sides of the upper outer surface of the first mounting strip 4 are rotatably connected to the left and right sides of the upper outer surface of the first fixed bracket 1 via hinges 6; the baffle 11 is fixedly installed at the rear end of the inner cavity of the concave cover 10; the guide hole 14, the guide rod 15 and the helical spring 16, the two sets of guide rods 15 are located inside the concave cover 10, and the two sets of guide rods 15 are fixedly installed on the left and right sides of the front outer surface of the baffle 11; the two sets of guide holes 14 are opened on the left and right sides of the rear outer surface of the movable block 12; the upper inclined wedge block 13 is fixedly installed on the front outer surface of the movable block 12; the helical spring 16 is movably sleeved on the outer wall of the guide rod 15; one end of the outer surface of the helical spring 16 is fixedly connected to one side of the outer surface of the baffle 11, and the other end of the outer surface of the helical spring 16 is fixedly connected to one side of the outer surface of the movable block 12; the movable block 12 is slidably connected to the outer wall of the guide rod 15 through the guide hole 14.

[0027] It should be noted that this utility model is a protective cover for the copper busbar of the incoming line branch in a distribution box with a plastic shell. The first fixing bracket 1 is fixed to one side inside the distribution box, and the second fixing bracket 2 is fixed to the other side inside the distribution box. The first mounting strip 4 at one end of the plexiglass plate 3 is rotatably connected to the first fixing bracket 1 via a hinge 6, as shown in the attached instruction manual. Figure 1As shown, at this time, the upper inclined wedge 13 in the snap-fit ​​assembly 8 limits the second mounting strip 5 at one end of the plexiglass plate 3. When it is necessary to open the plexiglass plate 3, manually press the upper inclined wedge 13 in the snap-fit ​​assembly 8. The upper inclined wedge 13 drives the movable block 12 to slide along the inner wall of the concave cover 10. The movable block 12 squeezes the spiral spring 16 along the outer wall of the guide rod 15 through the guide hole 14, so that one end of the upper inclined wedge 13 enters the concave cover 10. Then the plexiglass plate 3 can be flipped open; close the plexiglass plate 3. When the glass plate 3 is in operation, the bracket only needs to flip the acrylic glass plate 3. After the acrylic glass plate 3 is flipped, it presses the upper outer surface of the upper inclined wedge block 13. The upper inclined wedge block 13 drives the movable block 12 to slide along the inner wall of the concave cover 10. The movable block 12 presses the spiral spring 16. When the acrylic glass plate 3 is limited by the limiting strip 9, the reaction force of the spiral spring 16 drives the upper inclined wedge block 13 to reset. The upper inclined wedge block 13 limits the acrylic glass plate 3. At this time, the limitation of the acrylic glass plate 3 is completed, and it is easy to operate.
