[0028] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Please refer to the following: Figure 1 and Figure 2 The present invention provides a convenient adjustable bookshelf for libraries. The convenient adjustable bookshelf for libraries includes four vertical support rods 10 arranged in a matrix and multiple shelves 20 spaced apart along the vertical direction and detachably connected to each vertical support rod 10.

[0030] Specifically, a shelf space for placing books is formed between any two adjacent shelves 20, and a book stand component 30 is connected to the shelf 20 at the top of each shelf space.

[0031] The library bookshelf provided in this embodiment, compared with the prior art, features a simple structure and low manufacturing cost due to its frame structure formed by four vertical support rods 10 and multiple shelves 20. Furthermore, the shelves 20 are detachably connected to each vertical support rod 10, enabling convenient adjustment of the shelves 20 and the corresponding shelf space. The book stand assembly 30 is positioned on the shelf 20 at the top of the corresponding shelf space, preventing it from falling and facilitating adjustment, thus enhancing its practicality.

[0032] In some embodiments, the vertical support rod 10 and the shelf 20 may be adopted as follows: Figure 2 and Figure 4 The structure shown. See also Figure 2 Each vertical support rod 10 has a vertical cavity. Each vertical support rod 10 has several hanging holes 11 on the side wall of the shelf 20 that connect to the vertical cavity, and the hanging holes 11 are spaced apart along the vertical direction.

[0033] Each shelf 20 is provided with four hanging shafts 23 that can be engaged with the corresponding hanging holes 11.

[0034] The shelves 20 are connected to the vertical support rods 10 via hook-and-hook pins 23 and hook-and-hook holes 11, facilitating easy assembly and disassembly. To accommodate adjacent shelves 20, only one or both shelves need to be moved and engaged with their corresponding hook-and-hook holes 11. Specifically, during connection, the hook-and-hook pins 23 on each shelf 20 are inserted one by one into the corresponding hook-and-hook holes 11 on each vertical support rod 10. This structure allows for easy adjustment of the shelves 20, accommodating books of different sizes.

[0035] To accommodate the vertical support rods 10, the shelf 20 needs to be a rectangular plate, and the shelf 20 is placed horizontally between the four vertical support rods 10. In order for each vertical support rod 10 to fit snugly against the shelf 20, each vertical support rod 10 is provided with a side wall that abuts against the shelf 20. The specific vertical support rod 10 can be a square tube for easy manufacturing.

[0036] In some embodiments, the mounting hole 11 may be as follows: Figure 2 The structure shown. See also Figure 2 Each mounting hole 11 is a long strip opening that is wider at the top and narrower at the bottom. This structure ensures that the corresponding mounting shaft 23 extends into the top of the mounting hole 11 and then moves down to form a snap-fit ​​with the bottom of the mounting hole 11, so as to ensure the fixed connection between the shelf 20 and the vertical support rod 10.

[0037] Specifically, each mounting hole 11 can ensure that the upper circular hole at the top, the lower circular hole below the upper circular hole, and the middle opening connecting the upper circular hole and the lower circular hole are all provided. The diameter of the upper circular hole is larger than the diameter of the lower circular hole, and the width of the middle opening is equal to the diameter of the lower circular hole.

[0038] In some embodiments, the aforementioned mounting shaft 23 may be adopted as follows: Figure 4 The structure shown. See also Figure 2 Each mounting shaft 23 includes a fixing post 231 arranged along the length of the shelf 20 and a limiting cap 232 fixed to the end of the fixing post 231. The outer diameter of the limiting cap 232 needs to be larger than the outer diameter of the fixing post 231. The fixing post 231 can correspond to the middle opening and slide in the mounting hole 11. The limiting cap 232 can limit the connection in the horizontal direction, thereby preventing the fixing post 231 from disengaging from the mounting hole 11.

[0039] In this embodiment, the fixing post 231 can be a quadrangular prism structure, which ensures that it will not rotate relative to the vertical support rod 10 after sliding into the middle opening. This ensures the structural stability of the frame body formed by the vertical support rods 10 and the shelves 20, and prevents the frame body from forming a deformable parallel four-bar structure. The limiting cap 232 can be a circular plate. In order to further ensure the stable engagement of the hanging shaft 23 and the hanging hole 11, the length of the fixing post 231 can be slightly less than the wall thickness of the vertical support rod 10, and the end face of the limiting cap 232 near the fixing post 231 is a conical surface.

[0040] In some embodiments, the shelf 20 described above may be as follows: Figure 3 and Figure 5 The structure shown. See also Figure 3 and Figure 5 Each shelf 20 includes a horizontally arranged rectangular frame 21 and a flat plate 22 located at the top of the rectangular frame 21. The rectangular frame 21 is connected to each vertical support rod 10. The rectangular frame 21 can ensure support for the flat plate 22, while increasing the structural strength to withstand the load from the flat plate 22, thereby ensuring the placement of books.

[0041] In this embodiment, the rectangular frame 21 can be formed by enclosing four square tubes, with two parallel and spaced square tubes serving as the long frame and the other two parallel and spaced square tubes serving as the wide frame. Four mounting shafts 23 are located at both ends of each long frame, and the length direction of the mounting shafts 23 is consistent with the length direction of the long frame.

[0042] In some embodiments, the book-standing component 30 described above may employ, for example... Figure 5 The structure shown. See also Figure 5 The book stand assembly 30 includes a slide rail 31 arranged horizontally in a rectangular frame 21 and a baffle structure 32 slidably connected to the slide rail 31.

[0043] The rectangular frame 21 creates an opening within it, which allows for the concealed placement of the slide rail 31 and the baffle structure 32. The baffle structure 32 restrains the books on the lower shelf 20, preventing them from collapsing.

[0044] It should be noted that there are two slide rails 31. Both slide rails 31 are set along the length of the long frame, and their two ends are connected to the two wide frames respectively. Specifically, the slide rail 31 can be a long cylindrical rod. One end passes through the two wide frames in sequence through the through hole set on the wide frame, and then is threaded to the external nut for easy disassembly and assembly. It can also facilitate the adjustment of the number of baffle structures 32.

[0045] In some embodiments, the baffle structure 32 described above can be as follows: Figure 2The structure shown. See also Figure 2 The baffle structure 32 includes a slider 321 that is slidably connected to the slide rail 31 and a vertical plate 322 whose top end is detachably connected to the slider 321.

[0046] The slider 321 has a sliding hole for connecting with the slide rail 31, facilitating a sliding connection. Since both the slider 321 and the upright plate 322 have a certain weight, they provide a damping effect with the slide rail 31. When a book contacts the upright plate 322, the bottom of the upright plate 322 experiences force, resulting in a torque on the assembly of the upright plate 322 and the slider 321. This creates significant damping between the slider 321 and the slide rail 31, counteracting the reverse force from the book. The upright plate 322 connected to the slider 321 also helps to restrain the book below, preventing it from collapsing.

[0047] In some embodiments, the vertical plate 322 and the slider 321 can be adopted as follows: Figure 5 The structure shown. See also Figure 5 The upright plate 322 and the slider 321 are bolted together. Since the height of the support space varies, this structure can ensure that the length of the upright plate 322 can be adjusted for different heights of support space, thus facilitating the replacement of the upright plate 322.

[0048] In some embodiments, the slider 321 described above can be as follows: Figures 5 to 6 The structure shown. See also Figures 5 to 6 To further ensure the fixing effect of the slider 321, the bookend assembly 30 may also include a limiting structure 33. The limiting structure 33 includes a fixed long strip 331 disposed on the bottom surface of the flat plate 22, a limiting slide post 332 slidably disposed on the slider 321 along the vertical direction, and a spring 333 for springing the limiting slide post 332. The fixed long strip 331 is disposed along the length of the long frame, and the bottom surface of the fixed long strip 331 is provided with a serrated structure. The limiting slide post 332 is slidably disposed in the slide cavity on the slider 321, and the limiting slide post 332 is provided with an annular abutment plate, which is also disposed in the slide cavity. The top end of the limiting slide post 332 can extend out of the slide cavity and correspond to the serrated structure, while the bottom end of the limiting slide post 332 extends out of the slide cavity and is provided with a handle.

[0049] In this embodiment, during the sliding of the slider 321, the limiting slide post 332 can be pulled downwards by pulling the handle, causing the top of the limiting slide post 332 to disengage from the serrated structure. After the slider 321 has slid to its position, the manual handle can be released, and the spring 333 will spring the limiting slide post 332 upwards, causing the top of the limiting slide post 332 to contact the serrated structure and form a lock, further preventing the book from collapsing.

[0050] In some embodiments, see Figure 1The library bookshelf provided in this embodiment may also include multiple reinforcing rods 40, each of which is horizontally arranged and can be connected to two adjacent vertical support rods 10 at both ends by bolts to increase structural strength.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
