[0031] The following is combined Figures 1 to 4 This utility model describes a double-door waterproof cabinet.

[0032] See Figures 1 to 4 As shown in the figure, the double-door waterproof cabinet provided in this embodiment of the utility model includes at least one sub-cabinet 100. The sub-cabinet 100 includes a cabinet body 110, a double-door cabinet assembly 120, and a door gap sealing mechanism 130.

[0033] The cabinet 110 has an internal receiving space with an opening on its outer side. An annular seal 111 is provided around the opening. The double-door cabinet assembly 120 includes two doors 121, which are positioned opposite each other on either side of the opening. The doors 121 are hinged to the corresponding sides of the opening, and an inwardly protruding sealing flange 1211 is formed on the inner edge of each door 121. The door gap sealing mechanism 130 includes a door gap sealing protrusion 131, a door gap sealing groove 132, and a door gap seal. Component 133, a door gap sealing protrusion 131 is provided on the outer edge of one of the cabinet doors 121, a door gap sealing groove 132 is provided on the outer edge of the other cabinet door 121, and a door gap sealing element 133 is provided in the door gap sealing groove 132; when the double-door cabinet assembly 120 is closed, the sealing protrusion 1211 and the annular sealing element 111 are sealed together, the door gap sealing protrusion 131 is located in the door gap sealing groove 132, and the door gap sealing element 133 and the door gap sealing protrusion 131 are sealed together.

[0034] It should be noted that the "inner edge of cabinet door 121" mentioned above specifically refers to the three sides of the edge of cabinet door 121 excluding the door seam side, and the "inner edge of cabinet door 121" specifically refers to the side of the edge of cabinet door 121 corresponding to the door seam.

[0035] The double-door waterproof cabinet provided by this utility model, when the double-door cabinet assembly 120 is closed, the sealing protrusion 1211 and the annular seal 111 seal together, sealing the connection between the cabinet door 121 and the opening of the cabinet body 110. Simultaneously, the door seam sealing protrusion 131 is located within the door seam sealing groove 132, and the door seam seal 133 seals with the door seam sealing protrusion 131, sealing the door seams of the two cabinet doors 121 on the left and right sides of the sub-cabinet 100. This achieves a comprehensive seal of the sub-cabinet 100, effectively isolating the storage space from the external environment and preventing rainwater from entering the cabinet. This solves the problem of water seepage gaps easily appearing in the central seam area of ​​the cabinet body 110, leading to unsatisfactory waterproofing.

[0036] Specifically, the double-door waterproof cabinet provided by this utility model includes at least one sub-cabinet 100. That is, the number of sub-cabinets 100 can be one or more, without special limitation. Each sub-cabinet 100 has an independent receiving space, with an opening on the outer side of the receiving space. An annular seal 111 is provided around the opening, and the annular seal 111 engages with a sealing protrusion 1211 on the inner edge of the cabinet door 121. When the double-door cabinet assembly 120 is closed, the sealing protrusion 1211 presses against the annular seal 111, effectively preventing external moisture from entering the receiving space. A door gap sealing mechanism 130 is used to seal the door gaps of the two cabinet doors 121 when the double-door cabinet assembly 120 is closed. The door gap sealing mechanism 130 includes a door gap sealing protrusion 131, a door gap sealing groove 132, and a door gap seal 133. The door gap sealing protrusion 131 is located on the outer edge of the cabinet door 121 and can tightly engage with the door gap sealing groove 132 on the other cabinet door 121 to form an effective sealing contact. The combination of the sealing protrusion and the groove further enhances the sealing effect through the door gap seal 133, which is pressed tightly when the cabinet door 121 is closed, providing additional sealing force and ensuring waterproof performance. In operation, the cabinet door 121 with the door gap sealing groove 132 is closed first, and then the cabinet door 121 with the door gap sealing protrusion 131 is closed.

[0037] The door gap sealing groove 132 and the door gap sealing protrusion 131 can be independent components, which can be set on the outer edge of the corresponding cabinet door 121 by means of welding, threaded fastener connection, etc., or they can be set as an integral part of the cabinet door 121. During the production process, the sealing protrusion and groove can be directly formed on the edge of the cabinet door 121, and there are no special limitations on this.

[0038] The annular seal 111 and the door gap seal 133 can employ flexible sealing strips or sealing airbags to ensure a good sealing effect. Flexible sealing strips are typically made of elastic materials such as rubber, silicone, or EPDM (Ethylene Propylene Diene Monomer), possessing good flexibility and durability, effectively adapting to contact surfaces of different shapes, and providing a continuous sealing effect. Sealing airbags, on the other hand, form a seal through inflation. Filled with gas, they have good elasticity and compressibility. When the cabinet door 121 is closed, the sealing airbag is compressed and tightly adheres to the gap, achieving a strong sealing effect.

[0039] See Figure 5 As shown, according to some embodiments of the present invention, the door gap seal 133 is engaged with the door gap sealing groove 132.

[0040] By engaging the door gap seal 133 with the door gap sealing groove 132, it is easy to disassemble and replace the door gap seal 133, making the operation simple.

[0041] In practice, a snap-fit ​​structure can be provided between the door gap sealing groove 132 and the door gap seal 133. For example, a slot can be provided on the door gap seal 133 to snap it into the edge of the door gap sealing groove 132.

[0042] See Figure 5 As shown, according to some embodiments of the present invention, the door gap seal 133 includes a main body 1331 and a sealing part 1332. The sealing part 1332 is disposed on the main body 1331. The main body 1331 is provided with a slot. The slot engages with the outer edge of the door gap sealing groove 132. When the double-leaf cabinet door assembly 120 is closed, the sealing part 1332 engages with the door gap sealing protrusion 131.

[0043] By setting the door gap seal 133 to include a main body 1331 and a sealing part 1332, the groove provided on the main body 1331 can be engaged with the outer edge of the door gap sealing groove 132 to ensure the stability of the door gap seal 133 during use and prevent it from shifting or falling off due to external forces. At the same time, when the split cabinet door assembly 120 is closed, the sealing part 1332 can be engaged with the door gap sealing protrusion 131 to achieve a good sealing effect at the door gap of the two cabinet doors 121.

[0044] When the door gap seal 133 needs to be replaced, the old seal can be easily removed by disengaging the locking structure between the door gap seal 133 and the door gap sealing protrusion 131, without the need for complicated tools. After disassembly, the new door gap seal 133 can be snapped onto the outer edge of the door gap sealing protrusion 131.

[0045] See Figure 5 As shown, according to some embodiments of the present invention, the door gap sealing groove 132 includes a first connecting part 1321, a second connecting part 1322 and a third connecting part 1323 connected vertically in sequence. The first connecting part 1321 is connected to the corresponding cabinet door 121. The first connecting part 1321, the second connecting part 1322 and the third connecting part 1323 form the door gap sealing groove 132. The door gap sealing protrusion 131 includes a fourth connecting part 1311 and a fifth connecting part 1312 connected vertically in sequence. The fourth connecting part 1311 is connected to the corresponding cabinet door 121. The fourth connecting part 1311 and the fifth connecting part 1312 form the door gap sealing protrusion 131.

[0046] By configuring both the door gap sealing groove 132 and the door gap sealing protrusion 131 as multiple vertically connected connecting parts, the door gap sealing groove 132 and the door gap sealing protrusion 131 can be integrally formed with the corresponding cabinet door 121 during processing, and directly formed by bending or other methods. This simplifies the manufacturing process of the cabinet door 121, reduces assembly steps, and improves processing efficiency. Simultaneously, the door gap sealing groove 132 formed by the first connecting part 1321, the second connecting part 1322, and the third connecting part 1323, and the door gap sealing protrusion 131 formed by the fourth connecting part 1311 and the fifth connecting part 1312, through their vertically connected component structure, create a tight-fitting area on the cabinet door 121, which enhances the sealing performance of the door gap sealing mechanism 130.

[0047] See Figure 5 As shown, according to some embodiments of the present invention, when the double-door cabinet assembly 120 is closed, a first gap 134 is provided between the first connecting part 1321 and the fourth connecting part 1311, and a second gap 135 is provided between the second connecting part 1322 and the fifth connecting part 1312.

[0048] By providing a first gap 134 between the first connecting part 1321 and the fourth connecting part 1311 and a second gap 135 between the second connecting part 1322 and the fifth connecting part 1312 when the double-door cabinet assembly 120 is closed, a guide channel for guiding rainwater can be formed by the first gap 134 and the second gap 135. This facilitates the guidance of rainwater to the bottom of the cabinet door 121 for centralized discharge, preventing water from accumulating at the door seams and thus reducing the risk of water leakage into the cabinet.

[0049] See Figure 5 As shown, the first gap 134 and the second gap 135 are both located outside the sealing position of the door gap seal 133, and will not have a negative impact on the sealing performance of the door gap seal 133.

[0050] See Figure 2 and Figure 4 As shown, according to some embodiments of the present invention, a relief groove 1212 is provided between the sealing flange 1211 and the door gap sealing protrusion 131 and the door gap sealing groove 132 for making way for the annular seal 111.

[0051] By providing clearance grooves 1212 between the sealing flange 1211 and the door gap sealing protrusion 131 and the door gap sealing groove 132 to allow the annular seal 111 to make way, interference between the sealing flange 1211 and the door gap sealing protrusion 131, and between the sealing flange 1211 and the door gap sealing groove 132 and the annular seal 111 can be prevented when the cabinet door 121 is closed, thereby ensuring that the sealing flange 1211 can smoothly cooperate with the annular seal 111.

[0052] In specific implementation, a recess or partition can be provided at the location between the sealing flange 1211 and the door gap sealing protrusion 131, and between the sealing flange 1211 and the door gap sealing groove 132 to form a clearance groove 1212.

[0053] As an example, in this embodiment, a partition is provided between the sealing flange 1211 and the door gap sealing protrusion 131, and between the sealing flange 1211 and the door gap sealing groove 132 to form a clearance groove 1212.

[0054] See Figure 2 and Figure 4 As shown, according to some embodiments of the present invention, when the double-leaf cabinet door assembly 120 is closed, the side of the clearance groove 1212 is sealed with the annular seal 111.

[0055] By setting the side of the clearance groove 1212 and the annular seal 111 to a sealing fit when the double-leaf cabinet door assembly 120 is closed, the sealing performance of the cabinet door 121 can be further improved, preventing water from entering the cabinet body 110 through the gap between the side of the clearance groove 1212 and the annular seal 111.

[0056] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the double-door waterproof cabinet includes multiple sub-cabinets 100, which are arranged adjacent to each other vertically or horizontally.

[0057] By configuring the double-door waterproof cabinet into multiple sub-cabinets 100, each sub-cabinet 100 can form an independent storage space. When maintenance or replacement of components within the storage space is required, only the door 121 of the corresponding sub-cabinet 100 needs to be opened, without fully opening the entire double-door waterproof cabinet door 121. This reduces the frequency of opening and closing compression of the annular seal 111 and door gap seal 133, thereby extending their service life. Furthermore, configuring the double-door waterproof cabinet into multiple sub-cabinets 100 ensures that the dimensions of the annular seal 111 and door gap seal 133 corresponding to each sub-cabinet 100 are within a reasonable range, preventing excessive size that could lead to deformation, loosening, and sealing failure.

[0058] As an example, in this embodiment, the double-door waterproof cabinet includes two sub-cabinets 100 arranged vertically adjacent to each other.

[0059] See Figure 4 As shown, according to some embodiments of the present invention, a drainage structure 1213 is provided at the bottom of the sealing flange 1211.

[0060] By setting a drainage structure 1213 at the bottom of the sealing flange 1211, water can be drained in time to prevent moisture accumulation, thereby avoiding water seepage into the cabinet door 121 or aging and damage to the seal caused by moisture.

[0061] The drainage structure 1213 may include drainage holes, drainage grooves, or drainage perforations, etc., and there are no special limitations on this.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
