Description

Technical Field

[0001] This utility model relates to the field of cultural products technology, specifically a multifunctional bookshelf. Background Technology

[0002] Bookshelves are an important tool for storing books, which people use frequently in their studies, daily life, and work.

[0003] Traditional home bookshelves are typically rectangular in shape and bolted together, making assembly and disassembly cumbersome. When accessing books, they are generally only accessible from the front. To prevent dust accumulation, the front of the bookshelf usually has two interlocking sliding doors. However, because the sliding distance of these doors is limited, when both doors are pushed to the same side, the middle section of the bookshelf is often blocked and difficult to reach, making book access inconvenient.

[0004] Therefore, existing home bookshelves have technical problems such as being difficult to assemble and disassemble, and not being convenient enough to access books. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a multifunctional bookshelf that is convenient to assemble and disassemble and to access books.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional bookshelf includes an upper disc, a lower disc, a cylindrical support frame, an outer rotating body, an inner rotating body, an outer baffle, and an inner baffle;

[0008] The outer rotating body includes a first upper fan surface, a first lower fan surface, and a first vertical arc surface. The inner sides of the first upper fan surface and the first lower fan surface are respectively fixed to the upper and lower ends of the first vertical arc surface. The first vertical arc surface is parallel to the cylindrical support frame and is rotatably connected to the cylindrical support frame.

[0009] The inner rotating body is nested within the outer rotating body and includes a second upper fan surface, a second lower fan surface, and a second vertical arc surface. The inner sides of the second upper fan surface and the second lower fan surface are respectively fixed to the upper and lower ends of the second vertical arc surface. The second vertical arc surface is parallel to the first vertical arc surface and is rotatably connected to the first vertical arc surface.

[0010] There are two outer rotating bodies and two inner rotating bodies, with the two inner rotating bodies corresponding one-to-one with the two outer rotating bodies;

[0011] The middle parts of the upper and lower discs are respectively fixed to the upper and lower ends of the cylindrical support frame. The upper disc is snapped downwards onto the first upper fan surface of the two outer rotating bodies, and the first lower fan surface of the two outer rotating bodies is rotatably embedded into the lower disc.

[0012] The outer baffle is rotatably fitted onto the outside of the two first upper fan surfaces and the first lower fan surface, and the inner baffle is rotatably nested inside the outer baffle. Both the outer baffle and the inner baffle are arc-shaped and have a central angle greater than 180 degrees.

[0013] Furthermore, the outer side of the lower disc is provided with an upward circular groove, and the first lower fan surface of the two outer rotating bodies is provided with a downward arc-shaped protrusion, which is rotatably fitted into the circular groove.

[0014] Furthermore, the inner rotating body is provided with a limiting structure, which is used to limit the rotation angle between the outer rotating body and the inner rotating body.

[0015] Furthermore, the limiting structure includes a limiting protrusion located on one side of the second upper fan surface, and the limiting protrusion is arranged correspondingly to the side wall of the first upper fan surface.

[0016] Furthermore, the lower end of the outer side of the first upper fan surface and the upper end of the outer side of the first lower fan surface are provided with corresponding arc-shaped grooves, and the outer baffle is rotatably fitted into the arc-shaped grooves.

[0017] Furthermore, the central angles of the first upper fan, the first lower fan, the second upper fan, and the second lower fan are all greater than 90 degrees.

[0018] Furthermore, a handle is provided at the top of the upper disc.

[0019] Furthermore, the upper disc has a recessed portion in the middle, and a handle is located in the recessed portion.

[0020] Furthermore, the outer rotating body is provided with a first sandwich structure, and the inner rotating body is rotatably nested within the first sandwich structure.

[0021] Furthermore, the outer baffle is provided with a second sandwich structure, and the inner baffle is rotatably nested within the second sandwich structure.

[0022] In summary, this utility model has the following advantages:

[0023] This multifunctional bookshelf employs a structure where an outer rotating body is rotatably fitted into a cylindrical support frame, an inner rotating body is rotatably nested within the outer rotating body, an outer baffle is rotatably fitted into the outer rotating body, and an inner baffle is rotatably nested within the outer baffle. This design eliminates the need for bolt connections, making assembly and disassembly much easier. The inner rotating body can rotate out or in from the outer rotating body to accommodate different space requirements. When the inner baffle rotates out from the outer baffle, because the central angle between the outer and inner baffles is greater than 180 degrees, they completely enclose the outer side of the bookshelf, providing dust protection. To access books, either the inner or outer baffle can be rotated. Since the inner and outer baffles can rotate 360 ​​degrees around the cylindrical support frame, books can be accessed from any angle, enhancing convenience. Attached Figure Description

[0037] The present invention will now be described in further detail.

[0038] like Figure 1 As shown, a multifunctional bookshelf includes an upper disc 31, a lower disc 32, a cylindrical support frame 33, an outer rotating body 1, an inner rotating body 2, an outer baffle 41, and an inner baffle 42.

[0039] like Figure 2 , Figure 3As shown, the outer rotating body 1 includes a first upper fan surface 11, a first lower fan surface 12, and a first vertical arc surface 13. The inner sides of the first upper fan surface 11 and the first lower fan surface 12 are respectively fixed to the upper and lower ends of the first vertical arc surface 13. The first vertical arc surface 13 and the cylindrical support frame 33 are both arranged vertically. The first vertical arc surface 13 is parallel to the cylindrical support frame 33 and is rotatably connected to the cylindrical support frame 33, so that the outer rotating body 1 can rotate around the cylindrical support frame 33.

[0040] like Figure 4 As shown, the inner rotating body 2 is nested within the outer rotating body 1. Preferably, the outer rotating body 1 has a first sandwich structure 14, the shape of which matches the shape of the inner rotating body 2, and the inner rotating body 2 is nested within the first sandwich structure 14. The inner rotating body 2 includes a second upper fan surface 21, a second lower fan surface 22, and a second vertical arc surface 23. The inner sides of the second upper fan surface 21 and the second lower fan surface 22 are respectively fixed to the upper and lower ends of the second vertical arc surface 23. The second vertical arc surface 23 is parallel to the first vertical arc surface 13 and rotatably connected to the first vertical arc surface 13, so that the inner rotating body 2 can rotate around the cylindrical support frame 33 and rotate in or out of the outer rotating body 1.

[0041] In this embodiment, there are two outer rotating bodies 1 and two inner rotating bodies 2. The two outer rotating bodies 1 are arranged side by side, and the two inner rotating bodies 2 are respectively arranged in the two outer rotating bodies 1.

[0042] like Figure 7 As shown, the middle parts of the upper disk 31 and the lower disk 32 are respectively fixed to the upper and lower ends of the cylindrical support frame 33, and their longitudinal sections are I-shaped. The upper disk 31 is snapped downwards onto the first upper sector 11 of the two outer rotating bodies 1, and the first lower sector 12 of the two outer rotating bodies 1 is rotatably embedded in the lower disk 32.

[0043] Specifically, the outer side of the lower disc 32 is provided with an upward circular groove 321, and the first lower fan surface 12 of the two outer rotating bodies 1 is provided with a downward arc-shaped protrusion 15. The arc-shaped protrusion 15 is rotatably embedded in the circular groove 321, so that the outer rotating body 1 can rotate around the cylindrical support frame 33 on the circular groove 321 and will not come out of the lower disc 32.

[0044] The outer baffle 41 is rotatably fitted onto the outside of the two first upper fan surfaces 11 and the first lower fan surface 12, and the inner baffle 42 is rotatably nested within the outer baffle 41. For example... Figure 5 As shown, preferably, the outer baffle 41 is provided with a second sandwich structure 411, the shape of the second sandwich structure 411 matches the shape of the inner baffle 42, and the inner baffle 42 is rotatably nested in the second sandwich structure 411.

[0045] like Figure 5 , Figure 6As shown, the cross-sections of both the outer baffle 41 and the inner baffle 42 are arc-shaped with a central angle greater than 180 degrees. When the inner baffle 42 is rotated out from the outer baffle 41, the outer baffle 41 and the inner baffle 42 can completely cover the outside of the bookshelf, effectively preventing dust.

[0046] like Figure 4 As shown, the inner rotating body 2 is provided with a limiting structure, which is used to limit the rotation angle between the outer rotating body 1 and the inner rotating body 2.

[0047] Specifically, the limiting structure includes a limiting protrusion 211 located on one side of the second upper fan surface 21, which is arranged correspondingly to the side wall of the first upper fan surface 11. When the limiting protrusion 211 abuts against the side wall of the first upper fan surface 11, the inner rotating body 2 cannot continue to rotate forward into the outer rotating body 1, thereby limiting the rotation angle between the outer rotating body 1 and the inner rotating body 2, which facilitates the management of the rotation of the outer rotating body 1 and the inner rotating body 2.

[0048] like Figure 2 , Figure 3 As shown, the lower end of the outer side of the first upper fan 11 and the upper end of the outer side of the first lower fan 12 are provided with corresponding arc-shaped grooves 16, and the outer baffle 41 is rotatably fitted into the arc-shaped grooves 16. When the outer baffle 41 rotates on the arc-shaped grooves 16 of the two outer rotating bodies 1, it can rotate 360 ​​degrees around the cylindrical support frame 33, making it convenient to open the bookshelf from any angle and thus flexibly store and retrieve books.

[0049] Preferably, the central angles of the first upper fan surface 11, the first lower fan surface 12, the second upper fan surface 21, and the second lower fan surface 22 are equal and all greater than 90 degrees. With this structure, when the outer rotating body 1 and the inner rotating body 2 are fully extended, they can completely enclose the cylindrical support frame 33, thereby maximizing the use of the bookshelf space.

[0050] like Figure 1 , Figure 8 As shown, in order to facilitate moving the bookshelf, this utility model also provides a handle 312 at the upper end of the upper disc 31.

[0051] Specifically, the upper disc 31 has a recess 311 in the center, and a handle 312 is located within the recess 311. After pulling the handle 312 out of the recess 311, the bookshelf can be moved to the desired position, facilitating the rearrangement of spaces such as studies or studios, increasing flexibility and interest. When the handle 312 is returned to the recess 311, the upper disc 31 can be used for sitting, transforming the bookshelf into a cylindrical stool. The outer rotating body 1 and the inner rotating body 2 can also be removed separately and placed on a table or in a corner, thus giving the bookshelf more functions and increasing its practicality.

[0052] This utility model features a compact multifunctional bookshelf structure, convenient and diverse functions, and is economical and practical.

[0053] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
