[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] A type of distribution box that is easy to maintain, such as Figures 1-5 As shown, the device includes a housing 1 and a door 2 rotatably connected to the housing 1. The housing 1 has two through holes 3. Several fixing rods 4 are fixedly connected inside the housing 1. A placement plate 5 is slidably connected between the fixing rods 4. An extension block 6 is fixedly connected to the placement plate 5. A connecting strap 7 is fixedly connected to the extension block 6. The other end of the connecting strap 7 is fixedly connected to the door 2. When maintenance is required, the rotating door 2 can be opened. When the door 2 is rotated to a certain angle, the placement plate 5 will be pulled by the connecting strap 7. Then, if the door 2 is rotated further, the placement plate 5 will be pulled out, and maintenance work can be carried out.
[0022] like Figure 2 As shown, several tension springs 8 are fixedly connected between the placement plate 5 and the inner wall of the box 1. The tension springs 8 are respectively sleeved on several fixed rods 4. When the placement plate 5 is pulled by the connecting belt 7 after being rotated to a certain angle, the tension springs 8 will be in a stretched state. After the maintenance is completed, when the box door 2 is turned to close, the connecting belt 7 will no longer pull the placement plate 5, and the tension springs 8 will retract and reset, driving the placement plate 5 to reset.
[0023] like Figure 1 , Figure 4 , Figure 5 As shown, two fixed blocks 9 are fixedly connected to the box body 1. A spring telescopic rod 10 is fixedly connected to the fixed block 9. A hemispherical block 11 is fixedly connected to the telescopic end of the spring telescopic rod 10. When the box door 2 is in contact with the hemispherical block 11, the spring telescopic rod 10 is in a compressed state. When the box door 2 is opened for maintenance, the box door 2 will contact the hemispherical block 11 and then pass over the hemispherical block 11. When the hemispherical block 11 contacts the bottom side of the box door 2, the hemispherical block 11 will drive the spring telescopic rod 10 to deform into a compressed state. When the box door 2 completely passes over the hemispherical block 11, the spring telescopic rod 10 will reset and drive the hemispherical block 11 to reset. At this time, the hemispherical block 11 can restrict the box door 2 and prevent the tension spring 8 from continuously pulling the placement plate 5 to reset, which would require manual control of the box door 2.
[0024] like Figure 2 , Figure 4 , Figure 5As shown, two spring telescopic rods 12 are fixedly connected to the box body 1. A connecting plate 13 is fixedly connected to the telescopic end of the spring telescopic rods 12. A limiting post 14 is fixedly connected to the connecting plate 13. Two positioning blocks 15 are fixedly connected to the box door 2. The positioning blocks 15 have insertion slots 16 for the limiting post 14 to be inserted. When long-term maintenance is required, the connecting plate 13 can be rotated and pulled when the box door 2 is open to stretch the spring telescopic rods 12. Then, the limiting post 14 can be inserted into the insertion slots 16 on the adjacent positioning blocks 15. This avoids accidental contact with the box door 2, which would cause the spring telescopic rods 10 to retract. Subsequently, the box door 2 is pulled by the connecting belt 7, which would cause the placement plate 5 to reset.
[0025] like Figure 2 , Figure 4 , Figure 5 As shown, when the tension spring 8 is in normal condition, the two through holes 3 are located on the front and rear sides of the placement plate 5 respectively. The through hole 3 on the rear side of the placement plate 5 is more conducive to the insertion of the input line, while the through hole 3 on the front side of the placement plate 5 is more conducive to the insertion of the output line. By inserting the input line and the output line in this way, when the placement plate 5 moves, it can prevent the placement plate 5 from pushing against the input line and the output line, thereby preventing the connection from becoming loose.
