[0032] See also Figure 1-6 , the utility model provides a technical solution: a mobile bookshelf capable of changing its shape, comprising an adjustment unit 1;

[0033] And a placing unit 2 is arranged inside the adjusting unit 1 for placing books. The adjusting unit 1 includes an adjusting component and a fixing component arranged on the outer surface of the adjusting component. The placing unit 2 includes a lifting component arranged inside the adjusting unit 1 and a placing component arranged inside the lifting component.

[0034] The adjustment component includes an adjustment base 11, the inner wall of the adjustment base 11 is slidably connected to a movable base 2 12, the upper surface of the movable base 2 12 is provided with a slot 121, the upper parts of the adjustment base 11 and the movable base 2 12 are fixedly connected to a support frame 13, and the outer surface of the support frame 13 is provided with a through slot.

[0035] The upper surface of the adjustment base 11 is threadedly connected with a fixing bolt 14 , and one end of the fixing bolt 14 is movably engaged with the inner wall of the slot 121 .

[0036] The fixing assembly includes an ear plate 15 , one side of which is fixedly connected to the outer surface of the movable base 2 12 , the inner wall of the ear plate 15 is threadedly connected to a threaded rod 16 , and the bottom surface of the threaded rod 16 is fixedly connected to a rubber pad 17 .

[0037] When using the mobile bookshelf, if the length of the bookshelf needs to be adjusted, the fixing bolt 14 is turned to allow the mobile base 12 to slide freely on the inner wall of the adjusting base 11, thereby facilitating the adjustment of the distance between the support frames 13 on both sides, and then adjusting the length of the mobile bookshelf. After adjusting to a suitable position, the mobile base 12 and the adjusting base 11 are fixed by the cooperation of the fixing bolt 14 and the card slot 121. If the bookshelf needs to be fixed to prevent it from moving during use, the threaded rods 16 on both sides of the bookshelf are turned to make the rubber pads 17 contact with the bottom surface, thereby completing the fixing of the bookshelf.

[0038] The lifting assembly includes a positioning block 26, the outer surface of which is slidably connected to the through slot, and the inner wall of the positioning block 26 is detachably connected to an adjusting bolt 27, the outer surface of which is slidably connected to the inner wall of the through slot.

[0039] The placement assembly includes a placement rack 21, the inner wall of the placement rack 21 is slidably connected to a movable bracket 22, the upper surface of the movable bracket 22 is provided with a placement groove 221, the bottom surface of the movable bracket 22 is provided with a clamping groove 222, the inner wall of the placement rack 21 is threadedly connected with a fixing bolt 23, one end of the fixing bolt 23 is movably clamped with the inner wall of the clamping groove 222, and the outer surfaces of the placement rack 21 and the movable bracket 22 are fixedly connected with a lifting assembly.

[0040] An L-shaped placement plate 24 is detachably connected to the inner wall of the placement groove 221 , and a protective mesh plate 25 is fixedly connected to the upper surface of the L-shaped placement plate 24 and the placement rack 21 .

[0041] When the height of the bookshelf rack needs to be adjusted, the adjusting bolt 27 is turned to allow the positioning block 26 to slide freely on the inner wall of the support frame 13, thereby adjusting the height of the rack. After adjusting to a suitable position, the positioning block 26 is turned to fix the position of the rack. When the length of the mobile bookshelf needs to be adjusted, before adjusting the movable base 2 12 and the adjusting base 1 11, the L-shaped placement plate 24 is disassembled, and then the fixing bolt 23 is turned to allow the movable bracket 22 to slide freely inside the fixing bolt 23, thereby adaptively adjusting its own position according to the position between the adjusting base 1 11 and the movable base 2 12. Finally, after the adjustment is completed, the fixing bolt 23 is turned again to fix the rack 21 and the movable bracket 22 in cooperation with the clamping groove 222, and then the L-shaped placement plate 24 is placed in the original position. During the adjustment process, the number of L-shaped placement plates 24 can be increased or decreased according to the length of the bookshelf.

[0042] The following is a detailed description of the working principle of the shape-changing mobile bookshelf.

[0043] like Figure 1-6As shown, when the mobile bookshelf is used, if the length of the bookshelf needs to be adjusted, the fixing bolt 14 is rotated to allow the mobile base 12 to slide freely on the inner wall of the adjusting base 11, thereby facilitating the adjustment of the spacing between the support frames 13 on both sides, and then adjusting the length of the mobile bookshelf. After being adjusted to a suitable position, the mobile base 12 and the adjusting base 11 are fixed by the mutual cooperation of the fixing bolt 14 and the card slot 121. At the same time, before adjusting the mobile base 12 and the adjusting base 11, the L-shaped placement plate 24 is disassembled, and then the fixing bolt 23 is rotated to allow the mobile bracket 22 to slide freely inside the fixing bolt 23, thereby adaptively adjusting according to the position between the adjusting base 11 and the mobile base 12. The second fixing bolt 23 is rotated after the final adjustment is completed, and the mounting rack 21 and the movable bracket 22 are fixed with the engaging groove 222, and then the L-shaped mounting plate 24 is placed in the original position. During the adjustment process, the number of L-shaped mounting plates 24 can be increased or decreased according to the length of the bookshelf. If the bookshelf needs to be fixed to prevent it from moving during use, just rotate the threaded rods 16 on both sides of the bookshelf so that the rubber pads 17 contact the bottom surface, thereby completing the fixing of the bookshelf. When the height of the bookshelf mounting rack needs to be adjusted, the positioning block 26 is allowed to slide freely on the inner wall of the support frame 13 by rotating the adjusting bolt 27, thereby adjusting the height of the mounting rack. After adjusting to the appropriate position, the position of the mounting rack is fixed by rotating the positioning block 26.

[0044] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
