After one end of the grounding wire 12 is grounded, the other end can be extended into the power box 1 from the grounding wire hole 2 without friction with the rubber sealing ring 4. After the grounding wire 12 is connected to the equipment 11, the laying of the grounding wire 12 can be completed. After the grounding wire 12 is laid, the sealing ring mounting seat 5 is extended from the mounting seat receiving groove 7, and the two groups of rubber sealing rings 4 press the grounding wire 12 in the middle, thereby achieving the purpose of ensuring the sealing effect and preventing the grounding wire 12 from rubbing against the rubber sealing ring 4 during laying.

[0023] Embodiment 2

[0024] On the basis of the first embodiment, in order to realize the control of the sealing ring mounting seat 5, the two groups of mounting seat receiving grooves 7 are symmetrically distributed about the grounding wire 12, and a pull-out rod groove 8 is provided on the inner wall of the mounting seat receiving groove 7. The pull-out rod groove 8 is a cylindrical groove body, and a pull-out rod 6 is movably inserted in the pull-out rod groove 8. The pull-out rod 6 is a round rod structure, and one end of the pull-out rod 6 is fixed on the surface of one end of the sealing ring mounting seat 5 away from the rubber sealing ring 4, and the other end of the pull-out rod 6 is fixed with a spring 9. One end of the spring 9 away from the pull-rod 6 is fixed on the inner wall of the pull-rod groove 8. Two groups of lever windows 3 are opened on the surface of the power box 1. The two groups of lever windows 3 are symmetrically distributed about the grounding wire 12. The two groups of lever windows 3 are respectively connected with the two groups of pull-rod grooves 8. A lever 10 is movably connected in the lever window 3. One end of the lever 10 extends into the pull-rod groove 8, and the other end of the lever 10 extends from the lever window 3. The end of the lever 10 extending into the pull-rod groove 8 is fixed on the rod body of the pull-rod 6.

[0025] When the sealing ring mounting seat 5 needs to be retracted into the mounting seat receiving groove 7, the two sets of levers 10 are pushed to both sides at the same time, and the lever 10 moves from one end of the lever window 3 to the other end. The movement of the lever 10 causes the pull-out rod 6 to move in the pull-out rod groove 8. On the one hand, the movement of the pull-out rod 6 causes the spring 9 to be compressed by the inner wall of the pull-out rod groove 8 and the pull-out rod 6, and on the other hand, it drives the sealing ring mounting seat 5 to retract into the mounting seat receiving groove 7; when the sealing ring mounting seat 5 needs to be reset, the lever 10 is released, and the compressed spring 9 pushes the pull-out rod 6 back to its original position under the action of its own elasticity, and the pull-out rod 6 pushes the sealing ring mounting seat 5 to be reset.

[0026] When in actual use, for laying out the grounding wire 12, first retract the sealing ring mounting seat 5 into the mounting seat receiving groove 7.

Then, the grounding wire 12 is passed through the grounding wire hole 2 to lay out the grounding wire 12. When the grounding wire 12 is laid out, the control of the sealing ring mounting seat 5 is stopped. The two groups of sealing ring mounting seats 5 are automatically reset so that the two groups of rubber sealing rings 4 are pressed against the surface of the grounding wire 12. The grounding lightning protection device of the outdoor power supply box is implemented by dividing the rubber sealing ring 4 into two groups. The two groups of rubber sealing rings 4 are fixed on the surface of the sealing ring mounting seat 5 movably plugged into the mounting seat receiving groove 7. When the sealing ring mounting seat 5 is retracted into the mounting seat receiving groove 7, the distance between the two groups of rubber sealing rings 4 becomes larger. After one end of the grounding wire 12 is grounded, the other end can be extended into the power supply box 1 from the grounding wire hole 2 without friction with the rubber sealing ring 4, so as to connect the grounding wire 12 with the equipment 11. After the connection is completed, the layout of the grounding wire 12 can be completed. After the grounding wire 12 is laid, the sealing ring mounting seat 5 is extended from the mounting seat receiving groove 7, and the two groups of rubber sealing rings 4 press the grounding wire 12 in the middle, which achieves the purpose of ensuring the sealing effect and preventing the grounding wire 12 from rubbing against the rubber sealing ring 4 during the layout; when the sealing ring mounting seat 5 needs to be retracted into the mounting seat receiving groove 7, the two groups of levers 10 are simultaneously pushed to both sides, and the lever 10 moves from one end of the lever window 3 to the other end. The movement of the lever 10 causes the pull rod 6 to move in the pull rod groove 8. The movement of the pull rod 6 causes the spring 9 to be compressed by the inner wall of the pull rod groove 8 and the pull rod 6, and on the other hand, drives the sealing ring mounting seat 5 to retract into the mounting seat receiving groove 7; when the sealing ring mounting seat 5 needs to be reset, the lever 10 is released, and the compressed spring 9 pushes the pull rod 6 back to its original position under its own elastic action, and the pull rod 6 pushes the sealing ring mounting seat 5 to be reset.
