[0032] Reference Figures 1 to 7 This utility model provides a high-voltage circuit breaker retaining ring sealing assembly with self-locking function: including a retaining ring body 1 and a high-voltage circuit breaker housing 2, a mounting groove 3 is provided on one side of the retaining ring body 1, a rotating groove 4 is provided on the inner wall of the mounting groove 3, two locking grooves 12 are provided at the bottom of the inner wall of the mounting groove 3, multiple sliding grooves 5 are provided on the outer wall of the retaining ring body 1, a self-locking structure 6 and two safety components 7 are provided in the mounting groove 3, a sealing groove 8 is provided on the retaining ring body 1, and an elastic sealing ring 9 is locked in the sealing groove 8. The sealing performance is improved by the sealing of the elastic sealing ring 9. A retaining ring groove 10 is provided on one side of the high-voltage circuit breaker housing 2, and multiple locking grooves 11 are provided on the inner wall of the retaining ring groove 10.
[0033] To achieve self-locking, the self-locking structure 6 includes a rotating disk 601 rotatably connected inside the rotating groove 4. Multiple arc-shaped grooves 602 are formed on one side of the rotating disk 601. Multiple sliding rods 603 are fixedly connected inside the mounting groove 3. A push plate 604 is slidably connected to each sliding rod 603. A first return spring 608 is sleeved on each sliding rod 603. One end of each first return spring 608 is fixedly connected to one side of the mounting groove 3, and the other end is fixedly connected to one side of the corresponding push plate 604. The bottom of each push plate 604 is in contact with the inner bottom of the mounting groove 3. A locking block 605 is fixedly connected to one side of each push plate 604. Each locking block 605 is slidably connected in the corresponding sliding groove 5 and matches the corresponding locking groove 11. The other side of each push plate 604 is fixedly connected to... There is a movable block 606, and each movable block 606 has a fixed actuating post 607 on one side. Each actuating post 607 is slidably connected inside the corresponding arc groove 602. The rotating disk 601 drives the actuating post 607 to move through the arc groove 602. The actuating post 607 drives the movable block 606 to move. The movable block 606 drives the push plate 604 to slide on the corresponding sliding rod 603 and compress the first reset spring 608, so that the push plate 604 drives the locking block 605 to retract. Then, the retaining ring body 1 is inserted into the retaining ring groove 10. Then, the rotating disk 601 is reversed. Under the elastic reset of the first reset spring 608, the push plate 604 is pushed to move, so that the push plate 604 drives the locking block 605 to engage in the corresponding locking groove 11, thereby locking the retaining ring body 1 and reducing the risk of mechanical loosening and sealing failure due to high current impact.
[0034] To improve the stability of the rotating disk, the safety assembly 7 includes a sliding post 701 that is slidably connected to one side of the rotating disk 601.

The locking post 703 is adapted to the corresponding locking groove 12. A second return spring 704 is sleeved on the sliding post 701. One end of the second return spring 704 is fixedly connected to one side of the rotating disk 601, and the other end is fixedly connected to one side of the locking post 703. Under the elastic reset of the second return spring 704, the locking post 703 is pushed into the corresponding locking groove 12 to lock the rotating disk 601 and improve the stability of the rotating disk 601.
[0035] Working principle: During operation, the pull plate 702 is pulled by a tool, which moves the sliding column 701. The sliding column 701 moves the locking column 703, causing the locking column 703 to disengage from the slot 12. Then, the two sliding columns 701 are rotated, which drives the rotating disk 601 to rotate. The rotating disk 601 moves the actuating column 607 through the arc groove 602. The actuating column 607 moves the moving block 606. The moving block 606 drives the push plate 604 to slide on the corresponding sliding rod 603, compressing the first return spring 608, causing the push plate 604 to move the locking block 603. 5. Retract the retaining ring body 1 and then insert it into the retaining ring groove 10. Then reverse the rotating disk 601. Under the elastic reset of the first return spring 608, push the push plate 604 to move, so that the push plate 604 drives the locking block 605 to engage in the corresponding locking groove 11, thereby locking the retaining ring body 1 and reducing the risk of mechanical loosening and sealing failure due to high current impact. After locking, release the tool. Under the elastic reset of the second return spring 704, push the locking post 703 to engage in the corresponding locking groove 12, thereby locking the rotating disk 601 and improving the stability of the rotating disk 601.
