[0002] Sealing gasket is a kind of sealing spare part used in machinery, equipment, pipelines as long as there is fluid. It is a material with internal and external sealing function. It is used for sealing connections between pipelines and between parts of machinery and equipment.

[0003] For example, the utility model: "A sealing gasket with good anti-fracture effect", the announcement number is: "CN217271874U", this patent uses a limit column to limit the upper sealing gasket to prevent large deformation after force extrusion, and uses a stainless steel sheet to protect the upper sealing gasket, reduce wear, and have an anti-fracture effect. However, during the implementation of this patent, after the external bolts are installed on the sealing gasket, the bolts contact the sealing gasket and apply an extrusion force to the upper sealing gasket and the limit column, causing it to be locally subjected to a large extrusion force, and no force distribution structure is set on the sealing gasket, so that it is still easy to be broken due to the large extrusion force. Therefore, the research and development of new sealing gaskets with good anti-fracture effect has received more and more attention from researchers. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The sealing gasket with good anti-fracture effect is installed with a rubber support tray. When in use, after the external bolt is screwed into the first bolt installation through hole, the top of the bolt contacts the sealing gasket body and the rubber support tray. By using multiple sets of rubber support trays in combination, the bolts can be supported at the same time, and the extrusion force of the bolts on the sealing gasket with good anti-fracture effect can be shared by the multiple sets of rubber support trays;

[0014] 2. The sealing gasket with good anti-fracture effect is installed with a semicircular metal force-dividing sheet, a rubber force-guiding column and a rubber force-dividing column. The rubber support tray transmits the extrusion force to the semicircular metal force-dividing sheet through the rubber force-guiding column. The extrusion force can be evenly transmitted to multiple groups of rubber force-dividing columns through the arc structure of the semicircular metal force-dividing sheet, and the extrusion force can be evenly dispersed to different positions of the sealing gasket body through multiple groups of rubber force-dividing columns, so that different positions of the sealing gasket body can be evenly stressed, avoiding the local fracture of the sealing gasket body due to large extrusion force;

[0015] 3. The sealing gasket with good anti-fracture effect is installed with a lower sealing gasket, and a sealing gasket air cavity is arranged at the bottom of the lower sealing gasket. When the sealing gasket body is pressed together, the gas inside the sealing gasket air cavity can be pressed out, so that an adsorption force can be formed inside the sealing gasket air cavity, so that the lower sealing gasket is tightly attached to the connecting surface of the object, thereby effectively improving the sealing effect.

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.

[0021] See also Figure 1-3 The utility model provides an embodiment: a sealing gasket with good anti-fracture effect, comprising a lower sealing gasket 1, a sealing gasket body 2, a semicircular metal force dividing sheet 3 and a rubber support tray 4, the lower sealing gasket 1 is installed at the bottom of the sealing gasket body 2, and a second bolt mounting through hole 11 is provided at the middle position of the top of the lower sealing gasket 1, a first bolt mounting through hole 6 is provided inside the sealing gasket body 2, semicircular metal force dividing sheets 3 are evenly installed on the top of the sealing gasket body 2, and rubber force guiding columns 7 are evenly installed on the top of the semicircular metal force dividing sheets 3, and rubber support trays 4 are installed on the top of the rubber force guiding columns 7.

[0022] In this implementation:

[0023] Furthermore, a sealing gasket air cavity 10 is provided at the bottom of the lower sealing gasket 1, and the sealing gasket air cavity 10 is connected to the second bolt mounting through hole 11. When the sealing gasket body 2 is pressed together, the gas inside the sealing gasket air cavity 10 can be pressed out, so that an adsorption force can be formed inside the sealing gasket air cavity 10, so that the lower sealing gasket 1 is tightly attached to the connecting surface of the object, thereby effectively improving the sealing effect.

[0024] Furthermore, rubber force distribution columns 8 are evenly installed on the bottom of the semicircular metal force distribution sheet 3, and the ends of the rubber force distribution columns 8 away from the semicircular metal force distribution sheet 3 are connected to the sealing gasket body 2. The extrusion force can be evenly transmitted to multiple groups of rubber force distribution columns 8 through the arc structure of the semicircular metal force distribution sheet 3, and the extrusion force can be evenly dispersed to different positions of the sealing gasket body 2 through multiple groups of rubber force distribution columns 8, so that different positions of the sealing gasket body 2 can be subjected to uniform force, thereby avoiding local breakage of the sealing gasket body 2 due to large extrusion pressure.

[0025] Furthermore, six groups of semicircular metal force distribution plates 3 are provided, and the angle between two adjacent groups of semicircular metal force distribution plates 3 is sixty degrees.

[0026] Furthermore, a non-slip and wear-resistant rubber sheet 9 is installed on the top of the rubber support tray 4, which can not only prevent the bolts from rotating, but also reduce the wear on the rubber support tray 4.

[0027] Furthermore, three groups of rubber force component columns 8 are provided, and the distances between two adjacent groups of rubber force component columns 8 are the same.

[0028] Furthermore, a non-slip and wear-resistant rubber ring 5 is installed on the top of the sealing gasket body 2, which can not only prevent the bolt from rotating, but also reduce the wear of the sealing gasket body 2.

[0029] Working principle:

[0030] When in use, the sealing gasket body 2 is pressed against the connecting surface of the object, so that the lower sealing gasket 1 contacts the connecting surface of the object. When the sealing gasket body 2 is pressed, the gas inside the sealing gasket air cavity 10 can be pressed out, so that an adsorption force can be formed inside the sealing gasket air cavity 10, so that the lower sealing gasket 1 is tightly attached to the connecting surface of the object, thereby effectively improving the sealing effect;

[0031] Then the external bolts can be passed through the first bolt installation through hole 6 and the second bolt installation through hole 11, and the bolts can be tightened. After the bolts are tightened, the bolts are in contact with the anti-skid and wear-resistant rubber ring 5 and the anti-skid and wear-resistant rubber sheet 9, and apply extrusion force to the sealing gasket body 2 and the rubber support tray 4;

[0032] At the same time, the rubber support tray 4 transmits the extrusion force to the semicircular metal force distribution plate 3 through the rubber force guiding column 7. The arc structure of the semicircular metal force distribution plate 3 can evenly transmit the extrusion force to multiple groups of rubber force distribution columns 8, and the extrusion force can be evenly dispersed to different positions of the sealing gasket body 2 through multiple groups of rubber force distribution columns 8, so that different positions of the sealing gasket body 2 can be subjected to uniform force, thereby avoiding local breakage of the sealing gasket body 2 due to large extrusion pressure.
