It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

The disclosed embodiments provide a sealing structure, which may be in various different types such as a sealing ring, a sealing gasket, a sealing strip, and the like. The sealing structure can be applied to various mechanical equipment or electronic equipment. The sealing structure can be used for improving the sealing performance of equipment.

According to an embodiment of the present disclosure, there is provided a sealing structure, as shown in fig. 1 to 3, the sealing structure 2 including: a support layer 203, a first sealant 201, and a second sealant 202; the supporting layer 203 is made of a hard material, and the supporting layer 203 has a first surface and a second surface which are arranged oppositely. One of the first sealant 201 and the second sealant 202 is disposed on the first surface, and the other of the first sealant 201 and the second sealant 202 is disposed on the second surface. For example, the first sealant 201 is disposed on a first surface of the support layer 203 and the second sealant 202 is disposed on a second surface of the support layer 203. In the embodiment of the present disclosure, a hard support layer 203 is particularly added to the seal structure 2, and the strength and rigidity of the seal structure 2 can be improved by providing the support layer 203.

For a traditional sealing structure, taking a sealing ring which is commonly used as an example, the whole sealing ring is usually made of foam materials at present. The prepared sealing ring is soft in material and insufficient in hardness, and is easy to deform, tear and other adverse phenomena after being subjected to external force or used for a long time. This results in a reduction in the sealing properties of the sealing ring or in a direct loss of the sealing effect. Because of this, the seal ring needs to be replaced periodically.

The sealing structure 2 in the embodiment of the present disclosure is different from a conventional seal ring. In the embodiment of the present disclosure, the sealing structure 2 includes the supporting layer 203 made of a hard material, the supporting layer 203 has a suitable hardness, and the strength and the rigidity of the formed sealing structure 2 can be significantly improved by the supporting layer 203, so that the problems that the traditional sealing ring is soft in material, insufficient in hardness, and easy to deform and tear in use can be overcome.

In an embodiment of the present disclosure, the sealing structure 2 is designed as a multilayer composite structure. Particularly, the support layer 203 made of hard material is specially arranged in the sealing structure 2, and the first sealing layer 201 and the second sealing layer 202 are carried by the support layer 203, so that under the structural design, the structural strength and rigidity of the sealing structure 2 are improved, the sealing structure 2 is prevented from deforming and tearing due to large external force and long-term use, and the sealing structure 2 is prevented from being damaged in the assembling and disassembling process. Furthermore, since the sealing structure 2 has a rigid support layer 203, it is also advantageous for the assembly of the sealing structure 2 on a device. In addition, because the sealing structure 2 has certain strength and is not easy to damage, protective film layers such as release paper do not need to be arranged on the outer surface of the sealing structure, so that the subsequent operation step of peeling the release paper can be omitted, and the material and assembly cost can be reduced.

In one example of the present disclosure, as shown in fig. 1 and 2, the sealing structure 2 is a closed ring structure. Specifically, the seal structure 2 is, for example, a seal ring. Of course, the sealing structure 2 may also be in the form of a sealing gasket or a sealing strip, which is not limited in this disclosure.

In one example of the present disclosure, as shown in fig. 1 and 2, the sealing structure 2 is a closed ring structure, and at least one relief portion 204 is provided on the sealing structure in the circumferential direction. The avoidance portion 204 may be used to avoid components such as connectors. Therefore, when the sealing structure 2 is used for sealing, the situation that the sealing structure 2 blocks the passing of the connecting piece can be avoided, so that the connecting piece is directly punctured and the sealing structure 2 is damaged.

Specifically, the avoiding portion 204 is, for example, a mounting hole. Of course, the avoiding portion 204 may have other structures, and those skilled in the art can flexibly adjust the structure as needed.

Depending on the shape of the seal structure 2, the position at which the escape portion 204 is provided may be different. For example, the sealing structure 2 is a sealing strip, and one or more escape portions 204 may be provided in the sealing structure 2 along the longitudinal direction thereof. For another example, the seal structure 2 is a gasket, and one or more relief portions 204 may be provided along an edge portion of the seal structure 2.

In one example of the present disclosure, the support layer 203 is a resin material layer. That is, the support layer 203 in the sealing structure 2 may be made of a resin material. The resin material has a certain hardness after curing, which contributes to the strength and rigidity of the sealing structure 2.

The first sealing layer 201 is made of a soft material, and the second sealing layer 202 is also made of a soft material. The first sealant 201 and the second sealant 202 may be fixedly disposed on two opposite surfaces of the support layer 203, respectively. The first sealing layer 201 and the second sealing layer 202 can maintain sealability when sealing is performed.

In an example of the present disclosure, the first sealing layer 201 may be a foam material layer, a rubber material layer, or a silicone material layer. The foam material, the rubber material and the silica gel material are soft materials, and can keep the sealing property during sealing.

Specifically, the first sealing layer 201 may be attached to one surface of the support layer 203 and the second sealing layer 202 may be attached to the other surface of the support layer 203 by a hot press under high temperature and high pressure conditions. The support layer 203 can ensure that the formed sealing structure 2 has certain rigidity and strength, and the first sealing layer 201 and the second sealing layer 202 can ensure that the formed sealing structure 2 has good sealing performance.

In an example of the present disclosure, the first sealing layer 201 and the second sealing layer 202 are made of the same material, and both the first sealing layer 201 and the second sealing layer 202 are made of a rubber material layer or a silicone material layer. The rubber material and the silica gel material both have good elasticity and toughness, and the first sealing layer 201 and the second sealing layer 202 made of the two materials can also enable the sealing structure 2 to have good sealing performance.

When the first sealing layer 201 and the second sealing layer 202 are both made of a rubber material layer or a silicone material layer, and the supporting layer 203 is made of a resin material layer, the first sealing layer 201 and the second sealing layer 202 may be bonded to the supporting layer 203 by, for example, an adhesive. The first sealant 201, the support layer 203 and the second sealant 202 can be firmly bonded together by means of adhesive bonding.

Of course, the materials of the first sealing layer 201 and the second sealing layer 202 may be different.
