Detailed Description

The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, and merely illustrates the basic structure of the present invention in a schematic manner, and therefore it shows only the constitution related to the present invention.

As shown in fig. 1, the bookcase of the present invention comprises a first case body 1, a second case body 2, and a plurality of expansion plates 3 connecting the first case body 1 and the second case body 2, wherein the expansion plates 3 are fixedly connected with the first case body 1, the expansion plates 3 are slidably connected with the second case body 2, and the second case body 2 is provided with a plurality of sleeve plates 21 matching with the expansion plates 3.

As shown in fig. 2 and fig. 3, the retractable plate 3 is substantially a rectangular plate-shaped structure, wherein a first stopper 31 and a second stopper 32 are disposed on both sides of the retractable plate 3, the first stopper 31 is disposed at an end portion of a side surface of the retractable plate 3, the second stopper 32 is disposed at a position of the side surface of the retractable plate 3 near a middle portion, and an arc-shaped chute 33 is further disposed between the first stopper 31 and the second stopper 32; the bottom surface of the expansion plate 3 is also provided with a clamping device 34 for adjusting the expansion distance of the expansion plate 3 and a mounting groove 35 for mounting the clamping device 34; the clamping device 34 comprises a clamping ball 341 and an elastic member 342 abutted against the clamping ball 341, the mounting groove 35 comprises a bottom wall 351 facing the sleeve plate 21 and a top wall 352 correspondingly arranged with the bottom wall 351, an abutting hole 353 is arranged in the middle of the bottom wall 351, and the diameter of the abutting hole 353 is 1/2 of the diameter of the clamping ball 341; the clamping ball 341 is installed in the abutting hole 353 and partially exposed outside the abutting hole 353, one end of the elastic element 342 is fixedly connected to the top wall 352 of the installation groove 35, and the other end is vertically connected to the clamping ball 341.
