Common filing cabinets on the market include low cabinets with matte glass sliding doors, matte glass cabinets with open doors, matte double-door and double-section filing cabinets with matte glass, matte two-drawer sliding door combination cabinets, and metal cabinets, all of which use storage cavities or storage boxes, and books or documents are placed in the storage cavities or storage boxes in a mutually dependent manner.

[0003] Most of the existing filing cabinets are integrally formed, so the size of the cabinet is mostly fixed. In actual use, the height and storage space requirements of the filing cabinet are determined by factors such as the number of files to be stored. However, the existing filing cabinets cannot adjust their storage capacity according to actual storage needs, so there are some disadvantages in actual use. Therefore, a filing cabinet is urgently needed to solve this problem. Utility Model Content

[0027] How it works

[0028] When the file cabinet is in use, when it is necessary to expand the storage space of the file cabinet according to the actual demand for storing files, the two convex blocks 6 symmetrically fixedly connected at the lower end of the second box body 3 are first aligned and parallel with the two concave grooves 5 symmetrically opened on the top surface of the first box body 1, and then the two convex blocks 6 and the clamping strip 19 fixedly connected at the lower end of the second box body 3 are pushed into the inside of the two concave grooves 5 and the slide groove 7 respectively until the first box body 1 and the second box body 3 move to a vertically parallel state, and at the same time, the clamping slot opened at the lower end of the clamping strip 19 will be opposite to the clamping block 9 installed inside the slide groove 7. At this time, the first spring 10 at the lower end of the clamping block 9 will push the clamping block 9 fixedly connected at its upper end to move upward and clamp into the inside of the clamping slot opened at the lower end of the clamping strip 19, so as to limit the second box body 3 and thereby increase the storage space of the file cabinet. When it is necessary to reduce the storage space of the filing cabinet, first, the sliding extension and the lever 11 on the outside of the first box body 1 are pressed down, and the lever 11 drives the block 9 fixedly connected thereto to retract into the inside of the mounting groove 8, and at the same time, the first spring 10 is compressed until the block 9 moves out of the inside of the slot opened at the lower end of the card strip 19, and then the second box body 3 can be pushed to drive the two convex blocks 6 and the card strip 19 to move out of the inside of the concave groove 5 and the slide groove 7 respectively, so that the first box body 1 and the second box body 3 are separated, thereby reducing the storage space of the filing cabinet; at the same time, thanks to the setting of the limit cylinder 14, the telescopic rod 15, the second spring 17 and the push plate 16 in the storage box 4, the files placed in the storage box 4 can be squeezed, thereby preventing a large number of files from sliding against each other when placed in the storage box 4, resulting in the files being in a disorderly manner and inconvenient to take.
