[0038] Embodiments

[0039] Embodiments of the present application provide a sealing structure, as shown in Figures 1 to 4 including a sealing body 1 for sealing an outer door frame 4 and an outer door body 5, an elastic support 2, and an electromagnetic shielding layer 3.

[0040] The sealing body 1 is provided with a clamping portion 11 for connecting the outer door frame 4 and an abutting portion 12 for abutting the outer door body 5; through the design of the clamping portion 11 and the abutting portion 12, the tightness between the sealing body 1 and the outer door frame 4 and the outer door body 5 is enhanced, and the sealing effect is improved.

[0041] The sealing body 1 is provided with a clamping portion 11 for connecting the outer door frame 4 and an abutting portion 12 for abutting the outer door body 5; through the design of the clamping portion 11 and the abutting portion 12, the tightness between the sealing body 1 and the outer door frame 4 and the outer door body 5 is enhanced, and the sealing effect is improved.

[0042] The elastic support 2 is located in the accommodating cavity 13 of the sealing body 1 and is distributed in the axial direction of the sealing body 1, which can effectively support the sealing body 1 and prevent the sealing body 1 from losing elasticity due to compression or deformation during long-term use to some extent, thereby prolonging the service life of the sealing structure; and the elastic support 2 has a certain structural rigidity, which can enhance the overall strength of the sealing structure to some extent.

[0043] In addition, the elastic support 2 can also play a role in electromagnetic shielding, which is equivalent to a second electromagnetic shielding layer, achieving a double electromagnetic shielding effect and further enhancing the electromagnetic shielding performance of the sealing structure.

[0044] The outer surface of the sealing body 1 is provided with an electromagnetic shielding layer 3, which is distributed along the circumferential direction of the sealing body 1 with the opening 111 of the clamping portion 11 as the starting point.

[0045] The electromagnetic shielding layer 3 on the outer surface of the sealing body 1 can effectively block electromagnetic interference and prevent external electromagnetic waves from interfering with the equipment inside the door, and can be applied to environments that require high electromagnetic shielding protection, such as laboratories, communication rooms, electronic cabinets, etc. The wrapping of the electromagnetic shielding layer 3 enhances the electromagnetic shielding function of the sealing structure.

[0046] Therefore, through the combined arrangement of the sealing body 1, the elastic support 2 and the electromagnetic shielding layer 3, the sealing body 1 has good elasticity, weather resistance and electromagnetic shielding performance, can adapt to various use environments and meet the actual sealing needs of users.

[0047] Further, as shown in Figure 4 The sealing structure is used to seal the outer door frame 4 and the outer door body 5 to form a first space 61 inside the outer door body 5 and a second space 62 outside the outer door body 5;

[0048] And at least part of the electromagnetic shielding layer 3 is distributed on one side of the sealing body 1 close to the first space 61.

[0049] Optionally, the electromagnetic shielding layer 3 can be arranged along the circumference of the sealing body 1, thereby completely wrapping the sealing body 1. Of course, the electromagnetic shielding layer 3 can also be arranged along the circumference of the sealing body 1, thereby only wrapping part of the sealing body 1.

[0050] Understandably, when the electromagnetic shielding layer 3 only wraps part of the sealing body 1, at least part of the electromagnetic shielding layer 3 is arranged on the side of the sealing body 1 close to the first space 61, thereby reducing the use of electromagnetic shielding layer 3 material while maintaining the electromagnetic shielding function of the sealing structure, thereby reducing the use cost of the electromagnetic shielding layer 3 and obtaining good economic benefits.

[0051] And the electromagnetic shielding layer 3 is distributed on the side close to the first space 61, which can avoid damage or weathering of the electromagnetic shielding layer 3 by the external environment, thereby prolonging the service life of the electromagnetic shielding layer 3 and the sealing structure.

[0052] Further, as shown in Figure 1 and Figure 3 , the inner wall of the clamping part 11 is provided with a clamping protrusion 112, and the surface of the clamping protrusion 112 is provided with an electromagnetic shielding layer 3.

[0053] Optionally, the clamping protrusion 112 can be provided with one or more; of course, the specific number of clamping protrusions 112 is not limited, as long as it meets the connection requirements of the sealing structure and the outer door frame 4;

[0054] The surface of the clamping protrusion 112 is provided with an electromagnetic shielding layer 3, which helps to further optimize the electromagnetic shielding function of the sealing structure;

[0055] The clamping protrusion 112 is provided, which enhances the force point of the sealing structure and the outer door frame 4 or the outer door body 5, thereby enhancing the connection stability of the sealing structure and the outer door frame 4 or the outer door body 5; and the clamping protrusion 112 provides an additional support point during connection, which can disperse the external pressure, thereby improving the pressure resistance of the structure; the clamping protrusion 112 also helps to maintain the firmness of the connection when subjected to impact or vibration, reducing loosening or damage caused by vibration or impact.

[0056] Further, the thickness of the sealing body 1 is not less than the thickness of the elastic support 2, and the thickness of the elastic support 2 is not less than the thickness of the electromagnetic shielding layer 3.

[0057] The sealing body 1 is the part that directly contacts the external environment, and its thickness needs to be sufficient to provide better sealing performance to prevent gas, moisture or dust from entering; the thickness of the sealing body 1 is not less than the thickness of the elastic support 2, which can maintain good elastic performance of the sealing structure and maintain good contact and sealing effect under stress, preventing sealing failure due to material deformation or compression.

[0058] By reasonable setting of the thicknesses of the sealing body 1, the elastic support 2 and the electromagnetic shielding layer 3 in the sealing structure, the performance of the sealing structure can be coordinated and balanced, and the function of the sealing structure can be effectively realized, and economic benefits can be improved.

[0059] Further, as shown in Figure 1 , Figure 3 and Figure 4 , a cavity 14 is also provided along the extension direction of the sealing body 1, and the cavity 14 is used to enhance the sealing performance of the outer door frame 4 and the outer door body 5.

[0060] Understandably, the cavity 14 enhances the deformation ability and elasticity of the sealing body 1. When the sealing structure is subjected to external pressure, the cavity 14 is compressed, so that the sealing structure better fits the outer door frame 4 and the outer door body 5, and the sealing structure is in close contact with the outer door body 5 and the outer frame body, thereby realizing the sealing of the gap between the outer door frame 4 and the outer door body 5. In addition, the cavity 14 can be deformed to adapt to different sizes of the door gap, thereby enhancing the environmental adaptability of the sealing structure and having good versatility.

[0061] In addition, the cavity 14 also helps to form a buffer area, which can absorb the vibration generated when the sealing structure is connected to the outer door body 5, thereby protecting the sealing structure to a certain extent and avoiding sealing failure caused by external pressure or temperature change.

[0062] Further, as shown in Figure 1 , Figure 3 and Figure 4 , the side of the sealing body 1 close to the abutting portion 12 and / or the side of the sealing body 1 close to the cavity 14 is provided with a feeler 15.

[0063] The feeler 15 can form additional contact points or pressure points on the sealing contact surface, so that the pressure between the sealing body 1 and the sealed surface is more evenly distributed, avoiding local poor sealing, thereby improving the overall sealing effect. In addition, the feeler 15 has high elasticity and flexibility, which helps to enhance the elasticity of the sealing structure and can rebound and recover when compressed or deformed. Even when the external environment changes, the sealing part still maintains good sealing effect.

[0064] Understandably, the specific setting position and the number of the feeler 15 are not limited herein, as long as the elasticity of the sealing body 1 is enhanced, thereby enhancing the sealing performance of the sealing structure.

[0065] Further, the cross-sectional shape of the sealing body 1 and / or the cross-sectional shape of the elastic support 2 comprises a U shape, and the cross-sectional shape of the cavity 14 comprises any one of a circular shape, an elliptical shape or an olive shape.

[0066] The design of the U-shaped sealing body 1 can provide uniform pressure distribution between the sealing structure and the contact surface. During compression, the U-shaped sealing body 1 can effectively apply appropriate uniform pressure to the sealing surface, thereby reducing the possibility of leakage and enhancing the sealing effect; and the design of the U-shaped cross section can effectively enhance the compression resistance of the sealing body 1, avoiding compression fatigue of the traditional sealing structure.

[0067] The shape of the cavity 14 is set, which helps the cavity 14 to better adapt to the change of the sealing structure, and the change of the shape of the cavity 14 can effectively avoid the leakage of gas or liquid and improve the sealing effect.

[0068] For example, the cross-sectional shape of the cavity 14 is circular, which can uniformly distribute pressure, and the elliptical and olive-shaped cavity 14 can provide better contact and compression characteristics in specific assembly and working environment.

[0069] Further, the sealing body 1, the elastic support 2 and the electromagnetic shielding layer 3 are integrally formed.

[0070] Specifically, in some embodiments of the present application, the sealing body 1, the elastic support 2 and the electromagnetic shielding layer 3 adopt a screw extrusion combined with a tunnel furnace vulcanization process, which can be continuously produced automatically, effectively improving the production efficiency.

[0071] The integrally formed design can eliminate the connection problems between the sealing body 1, the elastic support 2 and the electromagnetic shielding layer 3, such as joint, poor contact or sealing failure, and tightly combine them to reduce the risk of loosening between the sealing body 1, the elastic support 2 and the electromagnetic shielding layer 3, thereby improving the overall reliability of the sealing structure and the sealing performance of the sealing structure.

[0072] Specifically, the sealing body 1 includes a rubber body or a vulcanized rubber body, the electromagnetic shielding layer 3 includes a conductive cloth layer, and the elastic support 2 includes a metal spring or a woven metal mesh.

[0073] The rubber body or the vulcanized rubber body has good elasticity, the metal spring or the woven metal mesh has good rigidity, and to a large extent, the flexibility of the sealing structure itself is also maintained, and the conductive cloth has good electromagnetic shielding performance.

[0074] In this way, the sealing structure enhances the performance of the sealing structure while reducing production costs and achieving good economic benefits.

[0075] More specifically, in some embodiments of the present application, the elastic support 2 comprises a plurality of sub-supports 21, the sub-supports 21 are provided with protrusions 211 in the axial direction, the protrusions 211 of different sub-supports 21 are sequentially connected, and gaps are generated between the sub-supports 21, so as to enhance the structural strength of the sealing body 1 while maintaining the flexibility of the sealing body 1 and the bending flexibility of the sealing structure.

[0076] More specifically, the metal elastic sheet or the woven metal mesh can be made of stainless steel or copper-coated steel.

[0077] The embodiments of the present application also provide a door with a sealing structure.

[0078] For example, the door can be a door of an electronic cabinet, a door of a safe, or a door used to close a shielded room or a machine room.

[0079] The door of the electronic cabinet enhances the sealing performance and the electromagnetic shielding performance of the electronic cabinet by using the sealing structure.

[0080] Of course, the specific structure of the door is not limited.

[0081] The embodiments of the present application have at least the following beneficial effects:

[0082] The present application provides a sealing structure and a door with the same, which has good elasticity, weather resistance and electromagnetic shielding performance, can adapt to various sealing environments, and meets the actual use requirements of users.

[0083] Specifically, the sealing body 1 is provided with a clamping portion 11 and an abutting portion 12, has good elastic performance, and enhances the sealing performance by being connected with the outer door frame 4 and the outer door body 5. The elastic support 2 is located in the sealing body 1 and is used to support the sealing body 1, thereby enhancing the structural strength of the sealing structure and maintaining the bending flexibility of the sealing structure. The outer surface of the sealing body 1 is provided with an electromagnetic shielding layer 3, which is distributed along the circumferential direction of the sealing body 1, thereby enhancing the electromagnetic shielding performance of the sealing structure.
