Description
Technical Field
[0001] This utility model relates to the field of vault door technology, and in particular to a double-leaf swing waterproof vault door. Background Technology
[0002] Waterproof vault doors are a special type of door that combines high-strength security with waterproof performance. They are designed for locations that need to withstand water immersion (such as floods, rainstorms, and groundwater seepage) and store high-value items or sensitive equipment. Existing waterproof vault doors generally feature a multi-layered protective structure. The outer layer is typically made of stainless steel, galvanized steel, or corrosion-resistant alloys to resist physical damage and rust. The interlayer is filled with fire-resistant materials (such as ceramic fiber) or a waterproof sealing layer to meet both fire and waterproof requirements. The door frame is equipped with a highly elastic rubber sealing strip or silicone gasket, forming an airtight / watertight barrier when closed. Some high-end models can achieve an IP67 / IP68 waterproof rating. More specifically, waterproof vault doors are reinforced with reinforced door bodies and hinges to withstand prolonged water pressure (such as flood impact) and external damage (such as prying and cutting). They employ dual control using waterproof electronic locks (such as biometric or combination locks) or mechanical locks, with the lock cylinder and electronic components waterproofed to ensure normal operation even after immersion in water. Some doors integrate drainage channels or emergency pressure relief devices to prevent structural deformation due to excessive water pressure. Automatic water-blocking strips or removable waterproof panels may be installed at the bottom of the door to cope with sudden rises in water levels.
[0003] However, based on the existing one-piece design of waterproof vault doors, vault doors lack an emergency exit to deal with situations where the main body of the door is obstructed from opening, resulting in insufficient flexibility in use and inadequate response to emergency situations.

The first main door leaf 200 is hinged to the corresponding side wall inside the main door frame 100 with a preset angle of movement. Conversely, the first auxiliary door leaf 300 is hinged to the corresponding side wall inside the main door frame 100 with a preset angle of movement. This allows the first main door leaf 200 and the first auxiliary door leaf 300 to form a swing vault door with a large opening angle in a double-opening manner, providing ample passage space. Specifically, the first auxiliary door 300, in conjunction with the first emergency door 400, is equipped with a first auxiliary door frame a. The first auxiliary door frame a is located in the middle of the main body of the first auxiliary door 300 and connects both sides of the first auxiliary door 300, thus forming a continuous passage space. Based on this, the first emergency door 400 is installed inside the first auxiliary door frame a, and the first emergency door 400 is hinged to the corresponding side wall inside the first auxiliary door frame a with a preset angle of movement. In response to actual passage needs, users can open the first emergency door 400 to enable the transfer of items or emergency passage of pedestrians when the first main door 200 and the first auxiliary door 300 are closed or when the first main door 200 and the first auxiliary door 300 are obstructed and cannot be opened. This greatly improves the flexibility of the vault door and ensures the vault door's emergency response capability. More specifically, the double-leaf swing waterproof vault door 10 also includes a first lock and a second lock. The first lock and the second lock are respectively installed on the first main door leaf 200 and the first emergency door 400 in sequence, so that the first emergency door 400 can be locked independently relative to the first main door leaf 200 and the first auxiliary door leaf 300, reducing the linkage between the doors, ensuring that the first emergency door 400 has the function of independent opening and closing, and further enhancing the flexibility of the vault door.
[0034] Furthermore, the first lock assembly includes several first mechanical combination locks 210, which are installed on the first main door leaf 200 to achieve a locking function between the first main door leaf 200 and the first secondary door leaf 300. Specifically, three first mechanical combination locks 210 are provided, which can be used in conjunction with three automatic scrambling devices in practical applications. The three first mechanical combination locks 210 can be configured to unlock any two of them to open the first main door leaf 200, thus balancing the security and ease of use of the vault door.
[0035] Furthermore, the second lock is equipped with a plurality of second mechanical combination locks 410, which are installed on the first emergency door 400 to achieve the locking function of the first emergency door 400.

The second emergency door 530 is installed on the second auxiliary door leaf 520, corresponding to the first emergency door 400, thereby forming the inner gate 500 as a whole.
[0038] In one embodiment, specifically, the second auxiliary door leaf 520 is provided with a through second auxiliary door frame b corresponding to the second emergency door 530, and the second emergency door 530 is hinged to the second auxiliary door frame b.
[0039] In one embodiment, specifically, the second main door 510 opens relative to the first main door 200 on the other side of the main door frame 100 to avoid interference between the second main door 510 and the first main door 200 during use; similarly, the second auxiliary door 520 opens relative to the first auxiliary door 300 on the other side of the main door frame 100 to prevent interference between the second auxiliary door 520 and the first auxiliary door 300 during use.
[0040] Furthermore, the inner gate 500 also includes a third lock, a fourth lock, and a fifth lock, which are respectively and sequentially installed on the second main door leaf 510, the second auxiliary door leaf 520, and the second emergency door 530 to realize the locking function of the inner gate 500.
[0041] In one embodiment, the third lock is specifically configured as a first electromagnetic lock 511 and a mechanical key lock 512. Both the first electromagnetic lock 511 and the mechanical key lock 512 are installed on the second main door 510, so that the second main door 510 can be electrically locked by the first electromagnetic lock 511 when it is powered normally. When the vault door is in a state of no power, the first electromagnetic lock 511 is automatically unlocked and the second main door 510 is locked by the mechanical key lock 512.
[0042] In one embodiment, specifically, the fourth lock is configured as a second electromagnetic lock 521, which is installed on the second auxiliary door leaf 520, so that the second auxiliary door leaf 520 can be electrically locked by the second electromagnetic lock 521 when it is powered normally.
[0043] In one embodiment, specifically, the fifth lock is also provided with a hook lock 531 so that the second emergency door 530 can be quickly unlocked in an emergency.
[0044] In summary, the double-leaf swing waterproof vault door disclosed in this utility model forms a swing vault door with a large opening angle by having the first main door leaf and the first auxiliary door leaf open in a double-opening manner, thus providing ample passage space. The first auxiliary door leaf, in conjunction with the first emergency door, is provided with a first auxiliary door frame.
