Description

Technical Field

[0001] The utility model relates to the technical field of sealing elements, in particular to a gasket for improving sealing effect. Background Art

[0002] Gaskets, also known as washers or gaskets, are mechanical seals that fill the space between two or more mating surfaces, typically used to prevent leakage from connected objects or entry into joined objects during compression. Depending on the shape and weak spots of the product, they are also used to secure the product and prevent it from moving during transportation, while also acting as a cushioning packaging component.

[0003] Authorization announcement number CN220453016U discloses a leak-proof sealing gasket. The device mainly adopts a gasket component 1, which is connected to the outer cover 1 and the flange 2, and the inner cover 1 and the inner cover 2, so that the flange 1 and the flange 2 will not be deformed due to excessive extrusion, thereby ensuring that the gasket can restore its elasticity after removal; a clamping component is provided, and a rocker plate is pressed by a top screw, so that the gasket component 1 and the gasket component 2 can be combined together and not easily misaligned. When one of the components needs to be replaced, it can be well positioned. However, in actual use, the device still has the following defects:

[0004] The above patent mainly avoids deformation of the gasket by setting up a flange docking method. However, when the gaskets are actually spliced, they usually need to be squeezed against each other for combination. When the gaskets are squeezed against each other, they are prone to deformation under the action of pressure, and it will make it difficult to accurately combine the sealing structure, resulting in gaps in the gaskets after splicing, affecting the sealing effect of the gaskets.
