After reading the specification, those skilled in the art can make modifications without creative contribution according to the needs, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.

[0028] Embodiment, such as Figures 1-8 As shown in the figure, a self-accessed intensive security file cabinet includes a plurality of file cabinet bodies 1 arranged in front and back and capable of moving forward and backward. The file cabinet body 1 can adopt the existing conventional cabinet structure, and can adopt the existing hand wheel or rocking handle driving mode for operation to control the file cabinet body 1 to move forward and backward to realize the close and separation of adjacent file cabinet bodies 1. When separated, a passageway is formed to facilitate the storage and access of files. When the storage and access operation is completed, the adjacent file cabinet bodies 1 are close to each other. Of course, the file cabinet body 1 can adopt the automatic control intensive cabinet in the prior art. A plurality of cabinet bodies can automatically walk and move to automatically close and separate. Such cabinet body is also relatively good.

[0029] The design gist of the present application is that at least one region of the left side region or the right side region of the file sub-cabinet body 1 is provided with an automatic storage and retrieval device for automatically storing and retrieving files, that is, the files are automatically stored and retrieved by mechanical structure, replacing manual operation. Specifically, the automatic storage and retrieval device comprises front and rear basic guide rails 21 extending front and rear on the left outer side or the right outer side of the file sub-cabinet body 1, a main support column 22 extending vertically and capable of moving front and rear on the front and rear basic guide rails 21, a file storage and retrieval moving bracket capable of moving left and right along the main support column 22 and capable of moving left and right between adjacent file sub-cabinet bodies 1 in front and rear, and a file automatic gripper capable of clamping and releasing files left and right mounted on the file storage and retrieval moving bracket. Through the automatic movement of the file storage and retrieval moving bracket, the file automatic gripper can be moved to the accurate file storage and retrieval position, and the storage and retrieval action is completed by clamping and releasing the file by the file automatic gripper. Of course, the automatic storage and retrieval device can be in the left side region of the file sub-cabinet body 1, or in the right side region, or in both sides, which will be more efficient. The main support column 22 can adopt an existing moving device column structure of aluminum alloy or other materials extending upward and downward in a rectangular shape. The front and rear movement between the main support column 22 and the front and rear basic guide rails 21 can be achieved by using the existing moving device.

Alternatively, the front and rear basic guide rails 21 use ordinary unpowered guide rails, and the slider thereon is a slider structure with a slider motor. Similarly, the main support column 22 is fixed on the slider with a motor. The front and rear movement of the main support column 22 can determine the general front and rear position, such as the position between two file sub-cabinet bodies 1 for storage and retrieval operation. After the front and rear position is determined, the file storage and retrieval moving bracket moves left and right into the area between the two opened file sub-cabinet bodies 1, that is, the aisle, and determines the specific left and right position of the file storage by moving left and right. Of course, the file storage and retrieval moving bracket is provided with an up and down moving structure, so as to realize three-dimensional file position positioning. The specific structure will be further described later.
