Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 4 The utility model provides an embodiment: a leakage-proof mechanical seal assembly, including a stationary ring 1, a connecting flange 2 is fixedly connected to one side of the outer wall of the stationary ring 1, a limiting slider 3 is fixedly connected to the lower surface of the stationary ring 1, a rotating shaft 4 is fixedly connected to the inner wall of the stationary ring 1, a moving ring 5 is rotatably connected to the outer wall of the rotating shaft 4, a slot 6 is provided inside the moving ring 5, the limiting slider 3 is slidably connected to the inner wall of the slot 6, a limiting slot 7 is provided inside the moving ring 5, a limiting block 8 is fixedly connected to one side of the outer wall of the moving ring 5, and the limiting block 8 The inner wall is slidably connected with a sealing ring 9, and a ball 10 is arranged on the upper surface of the sealing ring 9. The outer wall of the movable ring 5 is slidably connected with a sleeve 11. The upper side of the inner wall of the sleeve 11 is slidably connected with a limit ring 12, and the lower side of the inner wall of the sleeve 11 is slidably connected with a limit ring 2 13. The outer wall of the rotating shaft 4 is provided with an adjustment component; the adjustment component includes a spring 14, which is sleeved on the outer wall of the rotating shaft 4, one end of the spring 14 is fixedly connected to the inner wall of the limit ring 12, and the other end of the spring 14 is fixedly connected to the inner wall of the limit ring 2 13;

[0024] Specifically, by installing the limit slider 3 on the power device, the rotation of the dynamic ring 5 causes the limit slider 3 to slide limitedly on the inner wall of the slot 6. At this time, the dynamic ring 5 drives the ball 10 to rotate on the inner wall of the sleeve 11, so that the dynamic ring 5 rotates faster. At the same time, the spring 14 pushes the dynamic ring 5 to contact the outer wall of the slot 6 to ensure the sealing effect. The movement of the ball 10 further enhances the sealing effect to ensure that liquid or gas will not leak. This design improves the performance of the mechanical seal assembly and ensures the reliability and safety of the equipment operation.

[0025] Reference Figure 1 - Figure 4 , a plurality of connecting rods 15 are fixedly connected to the lower surface of the limiting ring 13, and the connecting rods 15 are slidably connected to the inside of the sleeve 11; a fixing ring 16 is fixedly connected to the lower surface of the connecting rod 15, and a slide groove 17 is provided inside the fixing ring 16; an annular slider 18 is rotatably connected inside the fixing ring 16, and the outer wall of the annular slider 18 is slidably connected to the inner wall of the slide groove 17; an adjusting sleeve 19 is fixedly connected to the outer wall of the annular slider 18, and the adjusting sleeve 19 and the outer wall of the sleeve 11 are both provided with internal threads 20; the adjusting sleeve 19 is rotatably connected to the outer wall of the sleeve 11, and the two internal threads 20 are threadedly connected; the sleeve 11 is rotatably connected to the inner wall of the limiting groove 7;

[0026] Specifically, by rotating the adjusting sleeve 19, the annular slider 18 moves on the inner wall of the slide groove 17, thereby adjusting the force of pushing the fixed ring 16 up and down. This causes the fixed ring 16 to push the connecting rod 15 to make it contact with the limiting ring 2 13. Subsequently, the limiting ring 2 13 pushes the limiting ring 1 12, thereby pushing the dynamic ring 5 and the static ring 1 to be more tightly combined. This mechanism ensures the reliability and stability of the mechanical seal assembly, effectively prevents the occurrence of leakage problems, and thus improves the performance and life of the equipment.

[0027] Working principle: When in use, by installing the limit slider 3 on the power device used, the limit slider 3 is allowed to slide on the inner wall of the slot 6 through the rotation of the moving ring 5, and then the moving ring 5 drives the ball 10 to rotate on the inner wall of the sleeve 11, so as to achieve the effect of facilitating the rapid rotation of the moving ring 5, and the spring 14 pushes the moving ring 5 to contact the outer wall of the slot 6, so as to achieve the sealing effect, and the ball 10 can achieve a further sealing effect. At this time, the adjusting sleeve 19 is rotated to make the annular slider 18 move on the inner wall of the slide groove 17, so as to achieve the effect of pushing the fixed ring 16 to rise and fall, and the fixed ring 16 pushes the connecting rod 15 to contact the limit ring 2 13, and the limit ring 1 13 pushes the limit ring 1 12, so as to further promote the dynamic ring 5 to fit closely with the static ring 1.
