DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0030] Reference Figure 1-Figure 7 A quick fixing device for a live-working power-taking box for a low-voltage distribution network comprises a box body 1 and a sliding cavity 5. The sliding cavity 5 is slidably connected in the box body 1. A spring 16 is fixedly connected between the sliding cavity 5 and the bottom wall of the box body 1. The spring 16 has a tendency to pull the sliding cavity 5 downward. A partition 2 is fixedly connected to the inner wall of the box body 1. The partition 2 is located on the upper side of the square block 8. The partition 2 is used for installing and fixing components. A door body 17 is hinged on the box body 1. The door body 17 can close the box body 1 to protect the components in the box body 1.
[0031] A fixing component is installed at the bottom of the box body 1, and the fixing component includes a square block 8, a rotating shaft 7, a slider 11, a suction cup 13, and a connecting pipe 12. A slide groove is opened on one side wall of the box body 1, and the two sliders 11 are slidably connected in the slide groove, so that the slider 11 can only slide horizontally in the slide groove. An inflatable bag 14 is fixedly connected between the sliders 11 and the ends of the slide groove, and the inflatable bag 14 is retractable. The two square blocks 8 are fixedly connected to the sliders 11 respectively, and the two square blocks 8 are slidably connected to the bottom wall of the box body 1. A vertical plate 23 is installed between the two plywood 24, and spiral holes are opened on the vertical plate 23 and the plywood 24. The two square blocks 8 are respectively threadedly connected to the two ends of the rotating shaft 7, and the slider 11 is fixedly connected with the plywood 24. The two suction cups 13 are fixedly connected to one side wall of the box body 1, and the suction cup 13 is connected to the inflatable bag 14 through the connecting pipe 12. The end of the suction cup 13 away from the box body 1 and the end of the vertical plate 23 away from the box body 1 are in the same horizontal line.
[0032] The fixing parts also include a swivel 10 and a baffle 9. The swivel 10 is rotatably connected to the side wall of the box body 1. The swivel 10 is slidably connected to one end of the shaft 7. The swivel 10 is not only slidably connected to the shaft 7, but also can drive the shaft 7 to rotate when rotating. A short rod is provided on the side wall of the box body 1, and the baffle 9 is rotatably connected to the short rod. A first torsion spring is provided between the baffle 9 and the outer side wall of the box body 1, and the baffle 9 can limit the swivel 10. When it is necessary to rotate the swivel 10, first pull the baffle 9 to rotate and no longer rotate the swivel 10, then pull out the swivel 10 and drive the shaft 7 to rotate. When it is not necessary to rotate the shaft 7, the swivel 10 can be pushed into the side wall of the box body 1, and then the baffle 9 is released to limit the swivel 10 again, so that the swivel 10 is hidden on the inner wall of the box body 1 to avoid rotation due to accidental contact from the outside.
[0033] A limiting component is installed on one side wall of the box body 1, and the limiting component includes a limiting plate 4, a rack plate 3, a rotating rod 18, and a protrusion 19. A through groove is opened on the side wall of the box body 1, and a docking block 25 is fixedly connected between the two limiting plates 4. A fixed block 20 is fixedly connected to one of the inner walls of the box body 1, and the fixed block 20 is located on the upper side of one of the limiting plates 4. The docking block 25 is slidably connected in the through groove. The two limiting plates 4 are respectively located on both sides of the side wall of the box body 1, and the protrusion 19 is fixedly connected to one of the limiting plates 4. A support rod 15 is fixedly connected to one of the limiting plates 4, and the two limiting plates 4 slide respectively on the box body 1. On both sides of one side wall, the rack plate 3 is fixedly connected to the upper surface of the sliding cavity 5, and the protrusion 19 is threadedly connected with a rotating rod 18. The end of the rotating rod 18 away from the protrusion 19 is meshed and connected with the rack plate 3. When the rack plate 3 rotates, it can drive the rotating rod 18 to rotate. When the rotating rod 18 rotates, it can drive the limiting plate 4 to move through the protrusion 19. The limiting component also includes a moving plate 6, one end of which is slidably connected in the sliding cavity 5. A storage groove for the sliding of the moving plate 6 is provided on the bottom wall of the box body 1. The storage groove has a limiting effect on the moving plate 6, so that the sliding cavity 5 cannot move to the bottom wall of the box body 1 under the pulling force of the spring 16.
[0034] A round rod 21 is rotatably connected to one of the inner walls of the box body 1, and a hinge plate 22 is rotatably connected to the end of the round rod 21 away from the box body 1. The hinge plate 22 is located on one side of the fixed block 20. A second torsion spring is provided between the hinge plate 22 and the inner wall of the box body 1. The hinge plate 22 can limit the support rod 15, and the second torsion spring can reset the hinge plate 22.
[0035] In the present invention, when in use, first the vertical plate 23 is fixed at the position where the box body 1 needs to be fixed externally, at this time, the two suction cups 13 are in contact with the smooth wall, and then the baffle plate 9 is pushed and drives the first torsion spring to deform, and as the baffle plate 9 rotates 180 degrees, the swivel 10 is no longer limited, and at this time the swivel 10 is pulled, the swivel 10 slides on the shaft 7, and then the swivel 10 is rotated and drives the shaft 7 to rotate, and when the shaft 7 rotates, it can drive the two square blocks 8 to slide in the center on the bottom wall of the box body 1, and when the two clamps 24 move in the center with the square blocks 8, the vertical plate 23 can be clamped, and the external pins are used to penetrate the threaded holes on the clamps 24 and the vertical plate 23 to achieve a quick fixation of the box body 1.
[0036] When the two square blocks 8 respectively drive the slider 11 to move in the center of the slide groove, they can stretch the inflatable bag 14 respectively. When the inflatable bag 14 is stretched, the inside of the inflatable bag 14 is under negative pressure. Since the suction cup 13 is connected to the inflatable bag 14 through the connecting pipe 12, when the inflatable bag 14 is stretched, the suction cup 13 is under negative pressure and can be tightly adsorbed on the wall, thereby achieving the effect of re-fixing the box body 1.
[0037] When it is necessary to inspect and repair the components in the box body 1, one end of the door body 17 is pulled so that the door body 17 and the box body 1 are in a vertical state. At this time, the movable plate 6 is pulled to slide in the sliding cavity 5. At this time, the movable plate 6 is separated from the storage slot at the bottom of the box body 1, and the movable plate 6 and the sliding cavity 5 move downward under the pulling force of the spring 16, and drive the rack plate 3 to move downward. The downward movement of the rack plate 3 can drive the meshing connected rotating rod 18 to rotate. The rotating rod 18 can drive the protrusion 19 and the limit plate 4 to move on the side wall of the box body 1 during the rotation process. The support rod 15 can push the hinge plate 22 to rotate as the limit plate 4 moves, and drive the second torsion spring to rotate. When the hinge plate 22 rotates to a certain angle, the support rod 15 The hinged plate 22 will pass over the hinged plate 22, and the hinged plate 22 will reset and rotate under the reset of the second torsion spring. Since the hinged plate 22 can only rotate in the direction away from the fixed block 20, the fixed block 20 can limit the hinged plate 22 to prevent the hinged plate 22 from rotating in the opposite direction. Therefore, the support rod 15 can be limited by the hinged plate 22 and the fixed block 20, and the reset movement of the limit plate 4 can also be avoided. When the limit plate 4 moves to the end protruding on one side of the box body 1, the door body 17 is between the two limit plates 4 at this time, which can limit the limit plate 4 to prevent the door body 17 from swinging with the wind when it is opened, and also ensure that the staff is not affected by the door body 17 when repairing the components in the box body 1.
[0038] When the door 17 needs to be closed, the limiting plate 4 is first pulled manually so that the support rod 15 moves away from the hinge plate 22 along with the limiting plate 4, and then the hinge plate 22 is pulled to rotate. At this time, when the hinge plate 22 no longer limits the support rod 15, the movable plate 6 and the sliding cavity 5 are pulled upward. As the sliding cavity 5 moves upward, the rack plate 3 can drive the rotating rod 18 to return to rotation. As the rotating rod 18 returns to rotation, the limiting plate 4 can be driven to return to the original position and no longer limit the door 17. Then the movable plate 6 is pushed into the storage slot, so that the door 17 can be closed to the box body 1.
[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
