Description

Technical Field

[0001] The utility model relates to the technical field of sealing gaskets, in particular to a combined sealing gasket. Background Art

[0002] Sealing gaskets are generally of an integrated structure, and larger sealing gaskets have a larger shape. Such sealing gaskets are made of a single material plate, which has the disadvantage of being relatively costly. In addition, they are difficult to store and transport. Based on this situation, some combined sealing gaskets have appeared on the market. However, when the existing combined sealing gaskets are used in combination, their sealing effect is poor, and they cannot adapt to the sealing needs of different sizes.

[0003] For example, a Chinese patent with the publication number CN204647299U discloses a combined sealing gasket, including a sealing gasket body, which in turn includes a plurality of sealing gasket splits. The surface of the sealing gasket body has a plurality of disconnections, which are formed by disconnection from the disconnections to form a plurality of sealing gasket splits. Sealant is coated on the side surfaces of the sealing gasket splits. The sealant layer at the disconnection is thicker than the sealant layer at other parts. The disconnection of the sealing gasket split has an inclined surface structure, which is a surface forming an angle with the side surfaces of the sealing gasket splits. There is sealant on the inclined surface structure, and the sealant layer at the disconnection is a silicone layer. Such a sealing gasket has the advantages of low cost and easy storage and transportation; it also has the advantage of tight sealing at the joints.

[0004] The combined sealing gasket involved in the above patent achieves the purpose of combined use, but the combined part of its two groups of separate sealing rings is very prone to leakage risk, the sealing effect is poor, and its size is fixed and cannot adapt to the sealing needs of different sizes. Therefore, we need to propose a combined sealing gasket. Utility Model Content
