[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-9The utility model provides a load box which is convenient for repairing an electric box, comprising a load box body 1, a load device 2 and a distribution box 3. A box door 4 is installed on the surface of the load box body 1, two partitions 5 are vertically arranged inside the load box body 1, and a wire groove 6 is arranged on the surface of the partition 5. The wire groove 6 is located below the distribution box 3, the load device 2 is installed between the partition 5 and the load box body 1, the distribution box 3 is installed between the two partitions 5, and a sliding mechanism is arranged between the distribution box 3 and the partition 5.

[0029] See also Figure 1 , 2 , 7 and 8, the distribution box 3 is arranged between the two load devices 2 and is also in the middle of the entire load box body 1, so that when the distribution box 3 is moved out from the inside of the load box body 1, it can be inspected from both sides of the distribution box 3, and it is also convenient to directly disassemble the distribution box 3. The distribution box 3 is suspended in the load box body 1, so that the connecting wires at the bottom of the distribution box 3 can be directly connected to the load device 2 through the wire trough 6, and when disassembling the distribution box 3, it is also convenient to first separate the connecting wires between the load device 2 and the distribution box 3.

[0030] The sliding mechanism includes a base plate 7, a C-shaped track 8, a connecting plate 9 and a counterweight rod 10. The C-shaped track 8 is fixedly arranged on the surface of the partition 5. Two connecting plates 9 are fixed on the surface of the base plate 7. Multiple counterweight rods 10 are vertically fixed between the two connecting plates 9. A sliding member is arranged on the surface of the connecting plate 9. The sliding member is connected with the C-shaped track 8. The distribution box 3 is installed on the surface of the base plate 7 through the connecting mechanism. The sliding member includes a roller 17, a receiving groove 18 and a connecting seat 19. The two connecting seats 19 are vertically arranged on the surface of the connecting plate 9, and one of the connecting seats 19 is attached to the surface of the partition 5. A receiving groove 18 is formed between the two connecting seats 19. The roller 17 is rotatably arranged on the inner wall of the receiving groove 18, and the surface of the roller 17 is in contact with the surface of the C-shaped track 8.

[0031] See also Figure 3 and 5 By pushing and pulling the distribution box 3, the distribution box 3 can drive the base plate 7 to move synchronously inside the load box body 1 through the connecting mechanism. When the base plate 7 moves, it can drive the connecting plate 9 to move synchronously. At this time, the connecting plate 9 can move synchronously through the connecting seat 19, and the connecting seat 19 can drive the roller 17 to move. Since the roller 17 is always in contact with the surface of the C-type track 8, when the roller 17 as a whole is translated, it can rotate on the surface of the C-type track 8, thereby converting the sliding friction into rolling friction, which can facilitate the translation of the base plate 7, so that the distribution box 3 can be moved to the outside of the load box body 1.

[0032] It should be noted that the distribution box 3 has gravity, and this part of the gravity will directly act between the roller 17 and the C-shaped track 8. Since the roller 17 is arranged on one side of the distribution box 3, the force on both sides of the roller 17 is unbalanced under the action of this part of the gravity. In this embodiment, a counterweight rod 10 is arranged between the two connecting plates 9. Through the setting of the counterweight rod 10, the gravity of the distribution box 3 can be balanced, so that the surface force of the roller 17 is balanced. However, since the distance from the counterweight rod 10 to the roller 17 (i.e., the force arm) is different from the distance from the distribution box 3 to the roller 17 (i.e., the force arm), the actual gravity of the counterweight rod 10 needs to be calculated, and only the corresponding mechanical structure is given in this scheme.

[0033] The connecting mechanism includes a U-shaped buckle 11 and a hanging ear 12. The hanging ear 12 is fixedly installed on the side of the distribution box 3 by bolts. The U-shaped buckle 11 is fixedly arranged on the surface of the base plate 7. The bent end of the hanging ear 12 is inserted into the inside of the U-shaped buckle 11.

[0034] See also Figure 3 and 6 The distribution box 3 is directly mounted on the surface of the U-shaped buckle 11 through the hanging ear 12. The detachable connection structure between the distribution box 3 and the substrate 7 is realized by the setting of the U-shaped buckle 11 and the hanging ear 12, so that the distribution box 3 can be disassembled as a whole after the substrate 7 drives the distribution box 3 to move to the outside.

[0035] It should be noted that, in this embodiment, only a specific structure of a connection mechanism is disclosed, and in practice, the connection can also be performed by connecting members such as bolts depending on the type of the distribution box 3 .

[0036] A limiting mechanism is arranged between the base plate 7 and the C-shaped track 8, and the limiting mechanism includes a limiting block 13, a slot 14, a claw 15 and a knob 16. The limiting block 13 and the slot 14 are respectively arranged on the two side surfaces of the C-shaped track 8, the knob 16 is fixedly arranged on the surface of the claw 15, and the claw 15 is rotatably arranged on the surface of the base plate 7. The depth of the slot 14 is the same as the thickness of the claw 15.

[0037] See also Figure 3 , 4And 9, through the above scheme, it can be known that by pulling the distribution box 3, the distribution box 3 can drive the substrate 7 to slide between the two partitions 5. At this time, the substrate 7 can drive the connecting plate 9 to slide synchronously on the surface of the C-shaped track 8. Assume that the movement is Y-direction movement. When the distribution box 3 is completely moved to the outside, that is, it moves to the maximum stroke. At this time, the connecting plate 9 just contacts the limit block 13, and then the claw 15 can be driven to rotate on the surface of the substrate 7 by turning the knob 16. When the claw 15 rotates, one end of the claw 15 can enter the slot 14. The cooperation of the slot 14 and the claw 15 can lock the substrate 7 in the Y direction, so that the substrate 7 cannot continue to move in the Y direction, which means that the substrate 7 cannot be reset at this time. At this time, the staff can inspect the distribution box 3, or separate the distribution box 3 from the surface of the substrate 7 before inspecting it.

[0038] A cooling fan 21 is fixedly provided on the surface of the base plate 7 via a bracket 20 , a cooling port 22 is provided on the top of the load box body 1 , a filter 23 is installed inside the cooling port 22 , and a cooling slot 24 is provided on the side of the load box body 1 .

[0039] See also Figure 1 , 2 and 4, the cooling fan 21 can absorb external gas into the load box body 1 through the heat dissipation port 22 and the filter 23, and then make this part of the gas dissipate heat to the distribution box 3, and the excess gas can dissipate heat to the load device 2 through the wire groove 6, and finally be discharged from the inside of the load box body 1 through the heat dissipation groove 24. In this process, the filter 23 can filter out foreign matter from the outside, and the cooling fan 21 also has a certain weight, so the gravity of the cooling fan 21 also needs to be added to the above-mentioned balancing process of the roller 17.

[0040] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
