Description

Technical Field

[0001] This utility model relates to the field of rainproof and waterproof equipment technology, and in particular to a rainproof structure for doors that can be applied to equipment such as generators. Background Technology

[0002] Generator sets are commonly used in infrastructure construction, communication sites, and disaster relief. Most generators operate outdoors, thus requiring high levels of rain and water resistance, especially silent generator sets. Current silent generator sets typically use soundproof enclosures, which generally only have sealing strips at the junction with the frame for waterproofing. However, in situations with very stringent waterproofing requirements, a seal using only rubber strips is insufficient; a reliable seal requires both structural integrity and the rubber strips. Currently, generator sets lack a reliable structural design for achieving this seal. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a simple, reasonably designed, and waterproof rainproof structure for generator soundproof enclosure frames.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a rainproof structure applied to the door frame of a generator soundproof cover, wherein a first sealing strip is provided on the side surface of the door frame facing the door panel, and a door panel folded edge is provided on the edge of the door panel aligned with the first sealing strip; a door frame folded edge is provided at the rear of the door frame extending toward the door panel, a second sealing strip is fixed on the door frame folded edge, and a third sealing strip is provided on the surface of the door panel aligned with the door frame folded edge; after the door panel is closed, a triple sealing structure is formed between the door panel and the door frame by the door panel folded edge pressing against the first sealing strip, the second sealing strip pressing against the door panel folded edge, and the door frame folded edge pressing against the third sealing strip.

[0005] Furthermore, the door frame fold is a U-shaped fold formed by folding the edge of the door panel toward the door frame. After the door panel is closed, the outer side of the U-shaped fold presses against the surface of the first sealing strip to form a first sealing structure.

[0006] Furthermore, the door frame fold is a hook-shaped fold formed by bending the edge of the door frame laterally toward the door panel and then bending it at an incline. The second sealing strip is fixed at the hook position of the hook-shaped fold. After the door panel is closed, the second sealing strip is pressed against the inner side of the end of the U-shaped fold.

[0007] Furthermore, the second sealing strip has a composite structure, which includes a fixing part and a pressing part, and the pressing part and the fixing part are connected to form an integral structure; the fixing part is tightly fixed to the hook part of the hook-shaped fold, and after the door panel is closed, the pressing part is pressed onto the U-shaped fold to form a second sealing structure.

[0008] Furthermore, the fixing part has a U-shaped structure, and the squeezing part has an O-shaped structure. The fixing part is inserted into the hook position of the hook-shaped fold and then covers the hook position. After the door panel is closed, the fixing part is pressed onto the third sealing strip to form a third sealing structure.

[0009] Preferably, both the first and third sealing strips are made of straight rubber, and the second sealing strip is also made of rubber.

[0010] This invention, through its triple sealing strip and specialized waterproof structure design, achieves excellent waterproofing, ensuring that even if rainwater seeps into the front sealing strip, it cannot ultimately enter the unit's interior, resulting in high reliability. Even under extreme rain conditions, the unit can operate normally without concern about water ingress damaging, corroding, or rusting internal electrical components. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] In the diagram, 1 is the door frame, 11 is the hook-shaped fold, 2 is the door panel, 21 is the U-shaped fold, 3 is the first sealing strip, 4 is the second sealing strip, 41 is the extrusion part, 42 is the fixing part, and 5 is the third sealing strip. Detailed Implementation

[0013] In this embodiment, refer to Figure 1 The rainproof structure applied to the door frame of the generator soundproof enclosure has a first sealing strip 3 on the side of the door frame 1 facing the door panel 2, and a door panel folded edge on the edge of the door panel 2 aligned with the first sealing strip 3; a door frame folded edge is provided at the rear of the door frame 1 extending toward the door panel 2, a second sealing strip 4 is fixed on the door frame folded edge, and a third sealing strip 5 is provided on the surface of the door panel 2 aligned with the door frame folded edge; when the door panel 2 is closed, the door panel folded edge presses against the first sealing strip 3, the second sealing strip 4 presses against the door panel folded edge, and the door frame folded edge presses against the third sealing strip 5, thus forming a triple sealing structure between the door panel 2 and the door frame 1.

[0014] The door frame fold is a U-shaped fold 21 formed by folding the edge of the door panel 2 toward the door frame 1. After the door panel 2 is closed, the outer side of the U-shaped fold 21 presses against the surface of the first sealing strip 3 to form a first sealing structure.

[0015] The door frame fold is a hook-shaped fold 11 formed by bending the edge of the door frame 1 laterally toward the door panel 2 and then bending it at an incline. The second sealing strip 4 is fixed at the hook position of the hook-shaped fold 11. After the door panel 2 is closed, the second sealing strip 4 presses against the inner side of the end of the U-shaped fold 11.

[0016] The second sealing strip 4 is a composite structure, which includes a fixing part 42 and a pressing part 41. The pressing part 41 and the fixing part 42 are connected to form an integral structure. The fixing part 42 is tightly fixed to the hook position of the hook-shaped fold 11. After the door panel 2 is closed, the pressing part 41 presses it onto the U-shaped fold 21 to form a second sealing structure.

[0017] The fixing part 42 has a U-shaped structure, and the squeezing part 41 has an O-shaped structure. The fixing part 42 is inserted into the hook position of the hook-shaped folded edge 11 and covers the hook position. After the door panel 2 is closed, the fixing part 42 is pressed onto the third sealing strip 5 to form a third sealing structure.

[0018] Thus, the first sealing strip 3 can effectively block most of the water entering from the door gap. Even if a small amount of water seeps in, it can be blocked by the hook-shaped fold 11, allowing the water to remain at the bottom of the door frame 1 and then flow out along the door frame 1. The second sealing strip 4 can block the water that remains at the bottom of the door frame 1 and cannot drain out in time, preventing water from entering the interior. The third sealing strip 5 is pressed and sealed with the hook-shaped fold 11, so as to ensure that even if water seeps in due to poor sealing of the previous sealing strip, the third sealing strip 5 can still achieve a sealing and waterproofing effect.

[0019] The first sealing strip 3 and the third sealing strip 5 are both made of straight rubber, and the second sealing strip 4 is also made of rubber.

[0020] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
