Description

Technical Field

[0001] This utility model relates to the field of outdoor waterproof sealing technology, and more specifically to the field of double-door waterproof structure technology. Background Technology

[0002] Outdoor server racks generally require an IP54 protection rating. To meet this requirement, most racks use a single-door design with a sealing strip, but internal space is limited. Double-door racks can better solve the space problem and facilitate internal assembly and maintenance, but they place much stricter demands on the rack's waterproof performance. Currently, there are two relatively common double-door rack designs, but both have shortcomings:

[0003] The existing design involves welding a central column in the middle of the rack frame, dividing the rack into two parts, each with its own independent sealing strip for waterproofing. However, the presence of the central column makes it difficult to install large equipment and results in low space utilization.

[0004] Existing Design Two eliminates the central support column mentioned in Existing Design One. Instead, a water-guiding channel is designed between the two cabinet doors, bent outwards. When the cabinet doors are closed, the water-guiding channel is pressed tightly against the door sealing strip, thus achieving a waterproof effect. However, in actual use, it is difficult to completely press and seal the water-guiding channel at the intersection with the door frame, making it prone to leakage.

[0005] Therefore, there is an urgent need to develop a new type of double-door structure to overcome the technical problems of low space utilization and poor waterproofing of existing double-door cabinets. Utility Model Content

[0006] The purpose of this utility model is to provide a double-door waterproof structure in order to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] This utility model provides a double-door waterproof structure, including a cabinet body, an opening on one side of the cabinet body, a door frame around the edge of the opening, a detachable central column in the middle of the door frame vertically, the detachable central column divides the door frame into a left door frame and a right door frame, and a first cabinet door and a second cabinet door are respectively hinged to the left door frame and the right door frame.

[0009] Both the left and right door frames have continuous waterproof folded edges, and the detachable central column has waterproof folded edges on both the left and right sides. The two door frame waterproof folded edges and the two column waterproof folded edges are located on the same plane and form two sealing surfaces on the left and right sides. The inner edges of the first and second cabinet doors are each provided with a sealing strip that is attached to and pressed tightly against the corresponding sealing surface.

[0010] Specifically, the detachable central column has waterproof flanges on both sides, and the door frame has waterproof flanges inside. After the detachable central column is connected to the door frame, the waterproof flanges of both are on the same plane and form two independent sealing surfaces with the door frame. The first and second cabinet doors each have independent and complete sealing strips on their inner sides. When the first and second cabinet doors are closed, the sealing strips are attached to and pressed tightly against the sealing surfaces, thereby achieving waterproofing.

[0011] Therefore, by using a detachable central column, the double doors can be transformed into two independent single doors, solving the problem of large equipment entering and exiting the cabinet, improving space utilization, and making waterproofing easier and more reliable.

[0018] In one embodiment, the sealing strips on the inner sides of the first and second cabinet doors are made of EPDM (ethylene propylene diene monomer).

[0019] In one embodiment, the sealing strip is a flat adhesive strip with self-adhesive backing.

[0020] This utility model provides a double-door waterproof structure, including a cabinet body, an opening on one side of the cabinet body, a door frame around the edge of the opening, a detachable central column in the middle of the door frame vertically, the detachable central column divides the door frame into a left door frame and a right door frame, and a first cabinet door and a second cabinet door are respectively hinged to the left door frame and the right door frame.

[0021] Both the left and right door frames have continuous waterproof folded edges, and the detachable central column has waterproof folded edges on both the left and right sides. The two door frame waterproof folded edges and the two column waterproof folded edges are located on the same plane and form two sealing surfaces on the left and right sides. The inner edges of the first and second cabinet doors are each provided with a sealing strip that is attached to and pressed tightly against the corresponding sealing surface.

[0022] Specifically, the detachable central column has waterproof flanges on both sides, and the door frame has waterproof flanges inside. After the detachable central column is connected to the door frame, the waterproof flanges of both are on the same plane and form two independent sealing surfaces with the door frame. The first and second cabinet doors each have independent and complete sealing strips on their inner sides. When the first and second cabinet doors are closed, the sealing strips are attached to and pressed tightly against the sealing surfaces, thereby achieving waterproofing.

[0023] Therefore, by using a detachable central column, the double doors can be transformed into two independent single doors, solving the problem of large equipment entering and exiting the cabinet, improving space utilization, and making waterproofing easier and more reliable.
