Abstract
Description
Technical Field
[0001] This utility model relates to the field of cabinet sealing technology, and in particular to a sealing structure for an outdoor waterproof power cabinet. Background Technology
[0002] Traditional outdoor power cabinets often employ single-layer sealing strips or simple sealing structures for waterproofing. These designs are prone to aging and deformation under prolonged exposure to rain, humidity, and other harsh environments, leading to decreased sealing performance and allowing moisture to seep into the cabinet, causing equipment malfunctions. Furthermore, existing sealing structures lack multi-stage sealing mechanisms, making it difficult to cope with the complex and ever-changing pressure variations of outdoor environments, resulting in limited sealing effectiveness. Therefore, there is an urgent need for a multi-stage sealing structure for outdoor waterproof power cabinets that is structurally stable and durable to solve these problems. Utility Model Content
[0003] In view of the problems existing in the background technology, this utility model proposes an outdoor waterproof power cabinet sealing structure.
[0004] The technical solution of this utility model is as follows: an outdoor waterproof power cabinet sealing structure, including a cabinet body, a cabinet door, a sealing element mounting groove, and a sealing element; the cabinet body is provided with a U-shaped sealing element mounting groove, and the cabinet door is hinged to the cabinet body; the sealing element is fixed on the cabinet door and corresponds to the position of the sealing element mounting groove; when the cabinet door is closed, the sealing element is embedded in the sealing element mounting groove to form a seal.
[0005] Preferably, the seal includes at least two levels of sealing strips, the sealing strips having a triangular cross-section and being stacked along the extension direction of the seal mounting groove.
[0006] Preferably, the sealing element includes a primary sealing strip, a secondary sealing strip, and a tertiary sealing strip, which are stacked and fixed in sequence, with gaps formed between adjacent sealing strips.
[0007] Preferably, the sealing element mounting groove is provided with multiple sealing rings; when the sealing element is embedded in the sealing element mounting groove, the sealing rings are located in the gap between the primary sealing strip, the secondary sealing strip and the tertiary sealing strip, and are tightly fitted with the side wall of the sealing strip.
[0008] Preferably, the inner wall of the sealing element mounting groove has a stepped structure, the shape of which matches the contour of the multi-level sealing strip of the sealing element to form a multi-level compression seal.
[0009] Preferably, the sealing ring is made of an elastic material and its outer diameter is larger than the gap width between adjacent sealing strips to provide radial compressive force.
[0010] Preferably, a waterproof adhesive strip is provided at the hinge joint between the cabinet body and the cabinet door, and the waterproof adhesive strip continuously covers the hinge axis.
[0011] Preferably, the height of each step of the stepped structure matches the compression stroke of the corresponding sealing strip to ensure that the sealing strip deforms uniformly under pressure.
[0012] Compared with the prior art, the present invention has the following beneficial technical effects:
[0013] The multi-level sealing mechanism enhances waterproof performance. By setting up a stacked structure of primary, secondary and tertiary sealing strips, combined with the stepped inner wall of the sealing component installation groove, a multi-level compression seal is formed, blocking water penetration layer by layer, which significantly enhances the waterproof reliability in outdoor environments.
[0014] The sealing ring strengthens the sealing gap. The elastic sealing ring set in the installation groove of the sealing element is embedded in the gap between the multi-level sealing strips. Utilizing the characteristic that its outer diameter is larger than the gap width, it provides radial compression force, fills the tiny gaps that may be caused by the deformation of the sealing strip, and further reduces the risk of water leakage.
[0015] The structural adaptability optimizes the sealing effect. The inner wall of the stepped sealing groove precisely matches the contour of the multi-level sealing strip, ensuring uniform deformation of the sealing strip under pressure, avoiding sealing failure caused by local stress concentration, and improving long-term stability.

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "vertical", "horizontal", "inner", "outer", "front", "back", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] like Figures 1 to 4 As shown, the present invention proposes an outdoor waterproof power cabinet sealing structure, including a cabinet body 100, a cabinet door 120, a sealing element mounting groove 110, and a sealing element 200; the cabinet body 100 is provided with a U-shaped sealing element mounting groove 110, and the cabinet door 120 is hinged to the cabinet body 100; the sealing element 200 is fixed on the cabinet door 120 and corresponds to the position of the sealing element mounting groove 110; when the cabinet door 120 is closed, the sealing element 200 is embedded in the sealing element mounting groove 110 to form a seal.
[0024] The combination of the recessed sealing groove 110 on the cabinet 100 and the sealing element 200 on the cabinet door 120 forms a basic sealing barrier when the cabinet door is closed, effectively preventing external moisture from directly seeping into the cabinet. This provides a foundation for the installation of subsequent multi-level sealing structures and ensures the integrity of the overall sealing frame.
[0025] The seal 200 includes at least two levels of sealing strips, each with a triangular cross-section, stacked along the extension direction of the seal mounting groove 110. The stacked arrangement of at least two levels of triangular cross-section sealing strips generates a larger contact area and more uniform deformation force during compression due to the characteristics of the triangular cross-section, forming a multi-level, layered barrier that significantly improves the reliability of a single seal, especially suitable for pressure fluctuations in outdoor environments.
[0026] The sealing element 200 includes a primary sealing strip 210, a secondary sealing strip 220, and a tertiary sealing strip 230, which are stacked and fixed in sequence, with gaps between adjacent sealing strips. The stacked design of the three sealing strips, combined with the gaps between adjacent sealing strips, allows each sealing strip to deform independently during compression, distributing pressure and avoiding seal failure caused by single-point overload; at the same time, it provides space for the embedding of the sealing ring 130, realizing a composite sealing mechanism.
[0027] Multiple sealing rings 130 are provided in the sealing element mounting groove 110; when the sealing element 200 is embedded in the sealing element mounting groove 110, the sealing rings 130 are located in the gap between the primary sealing strip 210, the secondary sealing strip 220 and the tertiary sealing strip 230, and are tightly fitted with the side wall of the sealing strip.
[0028] The sealing ring 130 is located in the gap of the sealing strip. Its elastic material is compressed when the seal 200 is embedded in the seal mounting groove 110, filling the gap and generating lateral extrusion force, eliminating the small gaps caused by the deformation of the sealing strip or manufacturing tolerances, and further enhancing the dynamic sealing effect.
[0029] The inner wall of the sealing groove 110 has a stepped structure, the shape of which matches the contour of the multi-stage sealing strip of the sealing element 200 to form a multi-stage compression seal. The matching design of the inner wall of the stepped sealing groove with the contour of the multi-stage sealing strip guides the sealing strip to compress step by step during the closing process, forming a gradient sealing pressure, avoiding tearing or permanent deformation of the sealing strip caused by local stress concentration, and improving long-term sealing stability.
[0030] The sealing ring 130 is made of an elastic material with an outer diameter larger than the gap width between adjacent sealing strips to provide radial compressive force. This design ensures that the sealing ring 130 remains pre-compressed after installation, providing continuous radial elasticity to compensate for gap widening due to temperature changes or material aging, thus maintaining long-term sealing performance.
[0031] A waterproof sealing strip is installed at the hinge between the cabinet body 100 and the cabinet door 120, and the waterproof sealing strip continuously covers the hinge axis. The continuous waterproof sealing strip at the hinge strengthens the weak sealing points in the hinge area of traditional power cabinets, preventing rainwater from seeping into the cabinet along the hinge gaps, and achieving all-round protection at the connection between the cabinet body and the cabinet door.
[0032] The height of each step in the stepped structure is matched to the compression stroke of the corresponding sealing strip to ensure uniform deformation of the sealing strip under pressure. This precise matching of step height with the compression stroke ensures uniform pressure on the sealing strip when closed, preventing inadequate sealing due to insufficient compression or accelerated material fatigue due to excessive compression, thereby extending the service life of the sealing structure.
[0033] The cabinet body 100 is provided with a U-shaped sealing element mounting groove 110. The cabinet door 120 is hinged to the cabinet body 100, and a sealing element 200 is provided on the cabinet door 120. The sealing element 200 corresponds to the sealing element mounting groove 110. When the cabinet body 100 and the cabinet door 120 are closed, the sealing element 200 enters the sealing element mounting groove 110 to form a seal. Further, the sealing element 200 includes a primary sealing strip 210, a secondary sealing strip 220, and a tertiary sealing strip 230. The cross-sections of the primary sealing strip 210, the secondary sealing strip 220, and the tertiary sealing strip 230 are all triangular. The seals are arranged in a stacked and fixed manner. When the seal 200 enters the seal mounting groove 110, the primary sealing strip 210, the secondary sealing strip 220, and the tertiary sealing strip 230 form a multi-level seal with the inner wall of the seal mounting groove 110, thereby improving the outdoor waterproof effect. Furthermore, there are multiple sealing rings 130 in the seal mounting groove 110. When the seal 200 enters the seal mounting groove 110, the sealing rings 130 are located in the gaps between the primary sealing strip 210, the secondary sealing strip 220, and the tertiary sealing strip 230, further improving the sealing effect.
