The fixed slide rail 21 passes through the anti-slip groove 24. A roller 25 is rotatably arranged at the top of the anti-slip groove 24. The roller 25 is rollingly connected in the positioning groove 22. The output end of the hydraulic push rod 45 extends outward to push the target movable cabinet 12 to move. During this process, the movable cabinet 12 moves along the fixed slide rail 21, and the roller 25 rolls inside the positioning groove 22 to perform mobile positioning and reduce friction resistance.

[0042] A vertical partition 1010 is provided in the middle of the cabinet 101, and a horizontal hollow frame 105 and a vertical hollow frame 104 are fixedly installed on both sides of the vertical partition 1010. An anti-slip barrier 106 is fixedly provided on the outer side of the horizontal hollow frame 105, so that after the files and archives are placed on the horizontal hollow frame 105, they will not slide and fall when the cabinet 101 is opened. At the same time, the horizontal hollow frame 105 and the vertical hollow frame 104 are conducive to the exhaustion of humid air inside the cabinet 101.

[0043] The hydraulic push rod 45 is fixedly arranged on one side of the movable cabinet 12, and the other side of the movable cabinet 12 and both sides of the fixed cabinet 11 are provided with mounting grooves 1011, and the output end of the hydraulic push rod 45 is fixedly installed in the mounting groove 1011, and the outer surfaces of the two outermost groups of movable cabinets 12 are installed with sealed cabinet doors 3.

[0044] A connecting seat 42 is fixedly installed at the output end of the hydraulic drive cylinder 41 , solenoid valves 43 are fixedly installed on both sides of the connecting seat 42 , and a connecting pipe 44 is fixedly installed between the hydraulic push rod 45 and the solenoid valve 43 .

The dehumidification mechanism 5 includes a dehumidifier 51 fixedly arranged on the back of the fixed cabinet 11. An exhaust pipe 53 is fixedly arranged on the back of the cabinet body 101. A connecting pipe 52 is installed between the multiple exhaust pipes 53 and the dehumidifier 51. The dehumidifier 51 is used for regular dehumidification during storage, so that the water vapor in the air inside the cabinet body 101 enters the dehumidifier 51 through the exhaust pipe 53 and is discharged outward, thereby ensuring the sealing effect of the file storage and preventing moisture.

[0046] The rotating handle 1081 is rotatably connected to the outer surface of the cabinet 101 , and the end of the rotating handle 1081 of the cabinet 101 and the end of the driving screw 1087 are fixedly installed with a transmission wheel 1084 , and a transmission chain 1083 is installed between the two sets of transmission wheels 1084 .

[0047] A locking gear 1085 is coaxially fixedly installed on the side of the transmission wheel 1084, and a linear motor 1088 is fixedly installed in the front inner wall of the cabinet 101. A locking card 1086 is fixedly installed on the output end of the linear motor 1088, and the end of the locking card 1086 is movably inserted into the outer surface of the locking gear 1085. The linear motor 1088 is controlled to start by the touch switch 102, so that the locking card 1086 slides upward and moves away from the outer surface of the locking gear 1085, so that the rotating handle 1081 is unlocked and can rotate freely. Conversely, after use, the locking card 1086 is driven by the linear motor 1088 to slide downward and get stuck on the outer surface of the locking gear 1085, thereby fixing the rotating handle 1081. At this time, the L-shaped pin 1082 cannot be moved and adjusted, so that the two adjacent groups of cabinets 101 are locked and cannot be opened.

[0048] The L-shaped latch 1082 is laterally slidably connected to the inner bottom of the cabinet 101, one end of the L-shaped latch 1082 is threadedly connected to the outer surface of the driving screw 1087, and a slot 107 is opened on the side of the cabinet 101. The other end of the L-shaped latch 1082 is movably connected to the slot 107. The opening width of the slot 107 is larger than the front end width of the L-shaped latch 1082. At the same time, the interior of the slot 107 is L-shaped. When the L-shaped latch 1082 is moved from the cabinet 101 to the interior of the slot 107, the handle 1081 is rotated counterclockwise so that the L-shaped latch 1082 is stuck in the inner wall of the slot 107, so that the two adjacent groups of cabinets 101 are connected to each other.

[0049] A sealing groove 109 is provided on one side of the cabinet 101 , and a sealing frame 1012 is fixedly provided on the other side of the cabinet 101 . Two adjacent sets of cabinets 101 are sealed by movably plugging the sealing frame 1012 into the sealing groove 109 .

[0050] Working principle: When the device is in use, the IC card is close to the RFID identifier 103 on the outer surface of the target cabinet 101, and the RFID identifier 103 recognizes it, and then the touch switch 102 is activated, and the linear motor 1088 is controlled by the touch switch 102 to start, so that the locking card 1086 slides upward and moves away from the outer surface of the locking gear 1085;

[0051] At this time, by rotating the rotating handle 1081 clockwise, the rotating handle 1081 drives the driving screw 1087 to rotate through the transmission chain 1083, and the L-shaped latch 1082 slides on the outer surface of the driving screw 1087, so that the end of the L-shaped latch 1082 moves from the side wall of the slot 107 of the adjacent cabinet 101 to the opening of the slot 107, and the L-shaped latch 1082 can be directly pulled out from the inside of the slot 107 to complete unlocking;

[0052] Then, the hydraulic drive cylinder 41 is started by the touch switch 102, and then the corresponding solenoid valve 43 is started, so that the hydraulic drive cylinder 41 injects hydraulic oil into the target hydraulic push rod 45, so that the output end of the hydraulic push rod 45 extends outward, thereby pushing the target movable cabinet 12 and the multiple groups of movable cabinets 12 on the side of the movable cabinet 12 to move synchronously away from the fixed cabinet 11 to complete the opening. During this process, the movable cabinet 12 moves along the fixed slide rail 21, and the roller 25 rolls inside the positioning groove 22, so as to move and position, and reduce friction resistance at the same time;

[0053] After the opening is completed, the operator enters between the two sets of cabinets 101 and consults the documents on the horizontal hollow frame 105 on the opposite side of the two sets of cabinets 101 in the open position, thereby increasing the number of documents that can be consulted after a single opening and making the opening convenient;

[0054] After use, the hydraulic drive cylinder 41 is started by the touch switch 102, and then the corresponding solenoid valve 43 is started, so that the hydraulic drive cylinder 41 extracts the hydraulic oil in the target hydraulic push rod 45, so that the output end of the hydraulic push rod 45 contracts inward, thereby pulling the target movable cabinet 12 and the multiple groups of movable cabinets 12 on the side of the movable cabinet 12 to move synchronously toward the side close to the fixed cabinet 11, and at this time, the L-shaped pin 1082 automatically enters the corresponding slot 107 to complete the closure, and when closing, the two adjacent groups of cabinets 101 are plugged and sealed through the sealing frame 1012 and the sealing groove 109, and then the rotating handle 1081 is rotated counterclockwise to make the L-shaped pin 1082 stuck in the inner wall of the slot 107, and cooperate with the hydraulic push rod 45 set at four points to achieve multi-point fixed sealing, and at the same time, the dehumidifier 51 is used for regular dehumidification during storage to ensure the sealing effect of file storage and prevent moisture.
