[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 not only achieves sealing by setting an outer seal and an inner seal between the upper gasket and the lower gasket, but also forms a cavity in the gap between the outer seal and the inner seal, so that the lower gasket and the upper gasket have a certain elasticity in the cavity, thereby improving the seismic performance of the sealing gasket. However, during the implementation of this patent, only the elasticity of the upper gasket and the lower gasket is used for buffering, and the seismic buffering effect is poor, and the impact force generated by the vibration cannot be effectively attenuated, so that the vibration is directly transmitted to the outside, and the seismic effect is poor.

During use, the internal anti-seismic supporting gasket is pressed on the anti-seismic buffer elastic rubber ring and the anti-seismic buffer elastic rubber sheet. When the vibration is transmitted to the internal anti-seismic supporting gasket, the internal anti-seismic supporting gasket is forced to vibrate, and the impact force generated by the vibration can be transmitted to the anti-seismic buffer elastic rubber ring and the anti-seismic buffer elastic rubber sheet, so that the anti-seismic buffer elastic rubber ring and the anti-seismic buffer elastic rubber sheet are forced to expand and contract, and the vibration can be buffered by the anti-seismic buffer elastic rubber ring and the anti-seismic buffer elastic rubber sheet;

[0015] 3. This kind of sealing gasket with anti-seismic function is provided with a guide groove and a rubber guide block. During use, it is guided by the guide groove and the rubber guide block so that the internal anti-seismic supporting gasket can only move in a straight line in the vertical direction, which can effectively improve stability.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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 anti-seismic function, including an external sealing gasket 1 and an internal anti-seismic supporting gasket 5, the internal anti-seismic supporting gasket 5 is installed inside the external sealing gasket 1, and both ends of the top of the external sealing gasket 1 are provided with guide grooves 3, both ends of the bottom of the internal anti-seismic supporting gasket 5 are evenly installed with anti-seismic buffer elastic rubber sheets 10, and the end of the anti-seismic buffer elastic rubber sheet 10 away from the internal anti-seismic supporting gasket 5 is connected to the external sealing gasket 1, second bolt mounting through holes 9 are provided at the four corners of the top of the external sealing gasket 1, and first rubber damping blocks 2 are installed at the bottom of both ends of the internal interior of the external sealing gasket 1.

[0022] In this implementation:

[0023] Furthermore, first bolt mounting holes 7 are provided at the four corners of the top of the internal seismic supporting gasket 5, and external bolts can be passed through the first bolt mounting holes 7 and the second bolt mounting holes 9, and the seismic buffer elastic rubber sheet 10 can be fixed to the connecting surface by bolts.

[0024] Furthermore, both ends of the top of the external sealing gasket 1 are evenly installed with shock-proof and buffering elastic rubber rings 8, and the end of the shock-proof and buffering elastic rubber ring 8 away from the external sealing gasket 1 is connected to the internal shock-proof supporting gasket 5. During use, the internal shock-proof supporting gasket 5 is pressed on the shock-proof and buffering elastic rubber ring 8 and the shock-proof and buffering elastic rubber sheet 10. When the vibration is transmitted to the internal shock-proof supporting gasket 5, the internal shock-proof supporting gasket 5 is forced to vibrate, and the impact force generated by the vibration can be transmitted to the shock-proof and buffering elastic rubber ring 8 and the shock-proof and buffering elastic rubber sheet 10, so that the shock-proof and buffering elastic rubber ring 8 and the shock-proof and buffering elastic rubber sheet 10 are forced to expand and contract, and the shock-proof and buffering elastic rubber ring 8 and the shock-proof and buffering elastic rubber sheet 10 can buffer the vibration.

[0025] Furthermore, second rubber damping blocks 11 are installed at the bottom of both ends of the internal seismic supporting gasket 5. When the internal seismic supporting gasket 5 shakes due to vibration, the internal seismic supporting gasket 5 drives the second rubber damping block 11 to move together, so that the second rubber damping block 11 and the first rubber damping block 2 can generate sliding friction, and the impact force generated by the vibration can be converted into friction force, which can attenuate the vibration, reduce the impact caused by the vibration, and improve the seismic effect.

[0026] Furthermore, rubber guide blocks 4 are installed on the tops of both ends of the internal seismic support gasket 5.

[0027] Furthermore, the cross-sectional shape of the anti-vibration buffer elastic rubber sheet 10 is "S"-shaped.

[0028] Furthermore, a mounting opening 6 is provided inside the internal anti-seismic supporting gasket 5 to facilitate mounting of an object thereon.

[0029] Working principle:

[0030] When in use, the external sealing gasket 1 contacts the connection surface, and an object is placed on top of the internal anti-seismic support gasket 5, and then the external bolts can be passed through the first bolt installation through hole 7 and the second bolt installation through hole 9, and the anti-seismic buffer elastic rubber sheet 10 can be fixed to the connection surface by bolts;

[0031] The object is pressed on the internal anti-seismic supporting gasket 5, so that the internal anti-seismic supporting gasket 5 moves downward and squeezes the anti-seismic buffer elastic rubber ring 8 and the anti-seismic buffer elastic rubber sheet 10. During use, the vibration on the object is transmitted to the internal anti-seismic supporting gasket 5, so that the internal anti-seismic supporting gasket 5 is forced to vibrate, and the impact force generated by the vibration can be transmitted to the anti-seismic buffer elastic rubber ring 8 and the anti-seismic buffer elastic rubber sheet 10, so that the anti-seismic buffer elastic rubber ring 8 and the anti-seismic buffer elastic rubber sheet 10 are forced to expand and contract, and the vibration can be buffered by the anti-seismic buffer elastic rubber ring 8 and the anti-seismic buffer elastic rubber sheet 10;

[0032] The internal anti-seismic supporting gasket 5 drives the second rubber damping block 11 to move together, so that the second rubber damping block 11 and the first rubber damping block 2 can generate sliding friction, which can convert the impact force generated by the vibration into friction force, thereby attenuating the vibration, reducing the impact caused by the vibration, and improving the anti-seismic effect.
