Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

Please refer to Figures 1-7. The present utility model provides a technical solution: a tool for installing a steel core sealing ring, which includes an outer disk 1. An inner disk 2 is rotatably connected to the inside of the outer disk 1. The central axis of the outer disk 1 and the inner disk 2 is In the overlapping state, as shown in Figure 4, the outer disk 1 includes two shells. After the two shells are spliced, the inner disk 2 can be clamped inside, which is used to install the inner disk 2 inside the outer disk 1, and at the same time, the inner disk 2 can be placed inside the outer disk 1. The interior of the outer disk 1 rotates. A plurality of inclined chute 3 are fixedly connected to the side wall of the outer plate 1 in the form of a circular array. The length direction of the chute 3 is staggered with the diameter of the outer plate 1. The inner plate 2 A plurality of slide seats 4 are fixedly connected in the form of a circular array on the inner wall of There is a slider 5. The upper end of the slider 5 is slidingly connected inside the chute 3 and is fixedly connected with an expansion component 6 for expanding or compressing the sealing ring. The outer skin of the sealing ring is made of polytetrafluoroethylene. The inner ring adopts a steel core structure, which combines the elasticity of a cast iron ring with the wear resistance of a PTFE ring.

As shown in Figure 2, in order to expand or compress the sealing ring, specifically, the expansion assembly 6 includes a column 601. The upper end of the column 601 is provided with a stopper 602. The upper end of the column 601 is There are support tables 603 on both sides of the block 602;

Method 1 for installing the sealing ring: Place the sealing ring on the support table 603, and the stopper 602 is attached to the inner wall of the sealing ring. At this time, the outer disk 1 and the inner disk 2 are relatively rotated, and the slider 5 moves away from the outer disk along the chute 3. 1. One end of the center of the circle moves, that is, the slider 5 moves on the slider 4 away from the center of the outer disk 1 (the slider 5 performs a diffusion movement). At this time, the sealing ring is opened by the stopper 602. In this state, the opened seal The ring can be placed on the outer wall of the shaft to install the sealing ring;

Method 2 for installing the sealing ring: Place the sealing ring on the support table 603, and the stopper 602 is attached to the outer wall of the sealing ring. At this time, the outer disk 1 and the inner disk 2 are relatively rotated, and the slider 5 approaches the outer disk along the chute 3. 1 moves one end of the center of the circle, that is, the slider 5 moves on the slider 4 close to the center of the outer disk 1 (the slider 5 performs contraction movement). At this time, the sealing ring is compressed by the stopper 602. In this state, the compressed sealing ring can Snap into the inner wall of the shaft to install the sealing ring.

As shown in Figures 6 and 7, in order to easily remove the sealing ring from the expansion assembly 6 when the sealing ring is expanded or compressed by the expansion assembly 6, specifically, the stopper 602 is slidably connected At the upper end of the column 601, a second spring 11 is provided below the stopper 602 for urging the stopper 602 upward. A pull rod 12 is slidably connected to the inside of the slider 5, and the upper end of the pull rod 12 is fixedly connected to on the lower side of the stopper 602, and the lower end of the pull rod 12 penetrates the side wall of the slider 5 and extends to the outside;

As shown in Figure 6, under the pressure of the second spring 11, the upper end of the stopper 602 penetrates the upper end of the column 601. In this state, after the sealing ring is placed on the support table 603, the sealing ring on the support table 603 is blocked by the stopper. 602 is blocked, the sealing ring can be expanded or compressed. When the expanded or compressed sealing ring is removed (at this time, the sealing ring is inserted outside or inside the shaft), pull the pull rod 12, causing the pull rod 12 to pull the stopper 602 At this time, the stopper 602 compresses the second spring 11 and retracts into the inside of the column 601 (as shown in Figure 7). After the sealing ring is loosened, the sealing ring is pressed against the side outside or inside the shaft through its own elastic force. on the wall.

As shown in Figures 1, 4 and 5, in order to be able to drive the inner disk 2 to slide inside the outer disk 1 so that the slider 5 takes the spreading assembly 6 to spread or gather together, specifically, the outer disk 1 is fixedly installed There are two fixed handles 7. A movable handle 8 is fixedly installed on the inner plate 2, and the movable handle 8 is between the two fixed handles 7. The side wall of the outer plate 1 is fixedly connected with at least one A fixed block 9. Both sides of the fixed block 9 are provided with a first spring 10 that can reset the inner disk 2 inside the outer disk 1. One end of the first spring 10 is fixedly connected to the fixed block 9. The first spring The other end of 10 is fixedly connected to the inner disk 2. Without the force on the inner disk 2, the first spring 10 presses the inner disk 2, causing the slider 5 to slide to the middle position of the chute 3. At this time, the movable handle 8 rotates to The middle position of the two fixed grips 7;

Pinch the movable handle 8 and any fixed handle 7 to each other, so that the movable handle 8 will move toward one side of the fixed handle 7, so that the movable handle 8 will drive the inner disk 2 to rotate inside the outer disk 1. When the inner disk 2 rotates inside the outer disk 1, the slider 5 can be prompted to slide inside the chute 3, causing the slider 5 to spread out or gather together with the expansion assembly 6. When the movable handle 8 is released, the third The spring 10 presses the movable handle 8 to rotate to the middle position of the two fixed handles 7 .

As shown in Figures 4 and 5, in order to assist the slider 5 to return and slide to the middle of the slide base 4, specifically, there are two sides of the slider 5 to assist the slider 5 to slide back to the middle of the slide base 4. The third spring 13, after the slider 5 slides in the slide base 4, the slider 5 will compress the third spring 13 on one side of the sliding direction. At this time, the elastic force of the third spring 13 is conducive to moving the slider 5. Reset and slide toward the middle of the slide base 4.
