[0028] Referring to Figures 1-5 as shown, the present utility model provides a technical solution: a graphite composite sealing gasket, including a graphite composite gasket 1

[0029] The following specifically describes its overall specific settings and functions

[0030] In this implementation: Three positioning pieces 3 are slidably inserted into the interior of the graphite composite gasket 1. A limiting ring 2 is rotatably connected to the outer side of the graphite composite gasket 1. Three connecting blocks 6 are uniformly fixedly connected to the lower side of the graphite composite gasket 1. The side wall of the connecting block 6 is provided with an inclined plane. The three positioning pieces 3 will be sleeved on the outer side of the component to be sealed, and it can prevent the graphite composite sealing gasket from shaking on the component to be sealed. A rectangular block 7 is fixedly connected to the lower end of the connecting block 6. An arc-shaped elastic piece 8 is fixedly connected to the side wall of the graphite composite gasket 1. The elastic piece 8 will press against the surface of the rectangular block 7, and relative movement will occur between the rectangular block 7 and the inclined plane of the positioning piece 3. A guide groove 5 is opened on the side wall of the positioning piece 3. A limiting block 4 is fixedly connected to the side wall of the graphite composite gasket 1. The surface of the guide groove 5 and the limiting block 4 are slidably connected. By setting the guide groove 5 to slide on the surface of the limiting block 4, it plays a role in restricting the moving direction of the positioning piece 3. A "V"-shaped groove is opened on one side of each of the three positioning pieces 3 close to each other. The "V"-shaped groove on the positioning piece 3 improves the tightness of limiting the cylindrical component to be sealed

[0031] Specifically, a number of reserved slots 12 are evenly arranged on the outer side of the limit ring 2. The reserved slots 12 on the limit ring 2 increase the friction force between the hand and the limit ring 2, facilitating the twisting operation of the limit ring 2. A supporting block 10 is fixedly connected to the side wall of the graphite composite gasket 1, and a clamping plate 11 is rotatably connected to the surface of the supporting block 10. The clamping plate 11 on the supporting block 10 can perform a rotating operation. The size of the clamping plate 11 is adapted to the size of the reserved slot 12. After the limit ring 2 is twisted by an appropriate distance, rotate the clamping plate 11 on the supporting block 10 and clamp the clamping plate 11 inside the reserved slot 12 adapted thereto, so as to realize the temporary supporting operation of the twisted limit ring 2.

[0032] Working principle: When it is necessary to install the graphite composite sealing gasket on a small-sized component to be sealed, first rotate the limit ring 2 away from the positioning piece 3. The reserved slots 12 on the limit ring 2 increase the friction force between the hand and the limit ring 2, facilitating the twisting operation of the limit ring 2. After the limit ring 2 is twisted by an appropriate distance, rotate the clamping plate 11 on the supporting block 10 and clamp the clamping plate 11 inside the reserved slot 12 adapted thereto, so as to realize the temporary supporting operation of the twisted limit ring 2. At this time, the positioning piece 3 can be flexibly twitched away from the pressure of the elastic piece 8 on the connecting block 6, and the graphite composite sealing gasket can be easily sleeved on the outer side of the component to be sealed. After the graphite composite sealing gasket is installed on the bottom side of the component to be sealed, rotate out the clamping plate 11 inside the reserved slot 12. At this time, the elastic piece 8 will press on the surface of the rectangular block 7, and relative movement will occur between the rectangular block 7 and the inclined surface of the positioning piece 3. At this time, the three positioning pieces 3 will be sleeved on the outer side of the component to be sealed, and the situation that the graphite composite sealing gasket shakes on the component to be sealed can be avoided, thereby improving the tightness of the later installation of the graphite composite sealing gasket. By setting the guiding groove 5 to slide on the surface of the limiting block 4, the moving direction of the positioning piece 3 is restricted. The "V"-shaped groove on the positioning piece 3 improves the tightness of limiting the cylindrical component to be sealed. By setting the above structure, the positioning and assembly work of the graphite composite sealing gasket on the outer side of the cylindrical component to be sealed is facilitated, thereby facilitating the stable sealing work between the components, and to a certain extent improving the stability of the graphite composite sealing gasket used on the smaller component to be sealed.

For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
