[0034] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of some known functions and components have been omitted.

[0035] This disclosure provides a through-hole sealing structure.

[0036] Figure 1 This is a schematic diagram of a through-hole sealing structure according to a disclosed embodiment, as shown below. Figure 1 As shown, a through-hole sealing structure according to a disclosed embodiment includes:

[0037] The plugging component 100 is used to seal the through hole 102;

[0038] The sealing medium 101 is disposed between the sealing member 100 and the through hole 102.

[0039] The sealing element 100 has a smaller cross-sectional area than the through hole 102, facilitating insertion into the through hole 102 for sealing. The sealing element 100 is a rigid structural component, providing structural strength for the sealing. The sealing medium 101 is used to create an interference fit, sealing the gap between the through hole 102 and the sealing element 100, maintaining sealing stability.

[0040] In one embodiment, the sealing medium 101 is a flexible material layer, such as flexible plastic, flexible asphalt, or flexible grease. Preferably, the sealing medium 101 can be attached to the sealing component 100 to adapt to the portability of sealing various sizes of through holes 102.

[0041] As a preferred embodiment, Figure 2 This is a schematic diagram of a preferred embodiment of a through-hole sealing structure, as shown below. Figure 2 As shown, the sealing component 100 includes:

[0042] A first mating component 200 is provided on one side of the through hole 102;

[0043] A second mating member 201 is provided on the other side of the through hole 102;

[0044] The first mating component 200 and the second mating component 201 cooperate to form a sealing structure for sealing the through hole 102, and the sealing medium 101 is disposed between the sealing structure and the through hole 102.

[0045] Wherein, the first mating part 200 is a first connecting structure, and the second mating part 201 is a second connecting structure;

[0046] The first connection structure and the second connection structure form a connection structure within the through hole 102.

[0047] The sealing structure is formed by the cooperation of the first mating part 200 and the second mating part 201, which improves the ease of installation of the sealing part 100. At the same time, the use of two mating parts can flexibly realize various sealing structures and help improve the stability of the sealing structure.

[0048] The sealing medium 101 is disposed on the surface of the first connection structure and / or the second connection structure, so as to facilitate the sealing medium 101 to form a mating relationship with the through hole 102 and ensure the sealing effect.

[0049] As one embodiment, the first connecting structure and the second connecting structure are adhesive structures, plug-in structures, or snap-fit ​​structures. Different structures are selected to accommodate different types of through-hole 102 sealing designs.

[0051] The protruding structure includes a body and a protruding portion;

[0052] The protrusion is used to pass through the through hole 102, and the locking structure is used to lock the protrusion.

[0053] In practical applications, the protrusion can be inserted into and pass through the through hole 102 from one side, and locked on the other side of the through hole 102 to form a stable structure based on the through hole 102. The sealing medium 101 is disposed on the surface of the protrusion to facilitate the mating relationship between the sealing medium 101 and the through hole 102.

[0055] Figure 4 This is a schematic diagram of a through-hole sealing structure in another engineering embodiment, as shown below. Figure 4 As shown, the screw 300 passes through the through hole 102, and the nut 301 locks the screw 300 on the other side, so that the screw 300 is stable in the through hole 102.

[0056] As a preferred embodiment, such as Figure 3 As shown, screw 300 is a large pan head screw, and sealing medium 101 is adhesive 302 located under nut 301. Depending on the selection of screw 300 size and the matching of adhesive 302, it can adapt to the sealing requirements of different types of through holes 102.

[0057] The through-hole sealing structure of any of the above-disclosed embodiments includes a sealing member 100 for sealing the through-hole 102 and a sealing medium 101 disposed between the sealing member 100 and the through-hole 102. By enriching the adaptability of the sealing medium 101, it can meet the sealing requirements of through-holes 102 of different sizes, ensuring the sealing effect of the photovoltaic inverter.
