Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a bookshelf folding table. Background Technology

[0002] Bookshelves are containers specifically designed for storing books. However, traditional bookshelf designs are limited to storage, with relatively singular functionality and constraints in use.

[0003] Furthermore, application number CN201520451583.X discloses a concealed folding desk that combines a bookshelf and a desk. When not in use, the desk can be folded onto the bookshelf, providing both bookshelf storage and additional desk functionality. However, the following technical problems remain: the design of the connecting components between the desk and bookshelf is unreasonable. Although the desk can be folded, the hinges are exposed on the tabletop when the desk is unfolded, causing inconvenience and potentially posing a safety hazard. Secondly, the latch is located at the top of the desk. When converting the desk from the unfolded to the folded state, it needs to be lifted and secured with the latch, requiring considerable strength for the elderly or children, making the operation difficult and inconvenient.

[0004] For example, in view of this, the present utility model is proposed. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] like Figures 1-5As shown, this utility model provides a bookshelf folding table, including a main frame 1, a first tabletop 2, a second tabletop 3, and a connecting component 4. The first tabletop 2 is mounted on the main frame 1 and connected to the second tabletop 3 via a hinge 5. The connecting component 4 is located below the first tabletop 2 and includes a first connecting rod 41 and a second connecting rod 42. The first end of the first connecting rod 41 is rotatably connected to the main frame 1, the second end of the first connecting rod 41 is rotatably connected to the first end of the second connecting rod 42, and the second end of the second connecting rod 42 is rotatably connected to the lower surface of the second tabletop 3.

[0038] The connecting component 4 is concealed beneath the first tabletop 2 and the second tabletop 3, thus not occupying desktop space or interfering with normal user operation. Furthermore, users will not directly contact the connecting component 4 during use, enhancing safety. The rotational connection between the first link 41 and the second link 42 forms a stable support structure, improving the stability and load-bearing capacity of the second tabletop 3 in its unfolded state.

[0039] Furthermore, the second tabletop 3 is connected to the first tabletop 2 via a hinge 5, allowing the second tabletop 3 to rotate relative to the first tabletop 2 around the central axis of the hinge 5. Simultaneously, the first connecting rod 41 and the second connecting rod 42 rotate with the second tabletop 3, providing stable support and guidance. Figure 1 , Figure 2 As shown, users can easily switch the desk between folded and unfolded states by simply lifting or lowering the second tabletop 3, reducing operational difficulty and improving ease of use.

[0040] Furthermore, there are two sets of hinges 5, symmetrically arranged on the lower surfaces of the first tabletop 2 and the second tabletop 3, to improve the connection stability and rotation smoothness between the first tabletop 2 and the second tabletop 3.

[0041] There are two sets of connecting components 4, which are symmetrically arranged below the second tabletop 3 to improve the stability and load-bearing capacity of the second tabletop 3 in the unfolded state.

[0042] As an optional implementation, such as Figure 3 , Figure 4 , Figure 5 As shown, the main frame 1 includes a column 11 and a connecting plate 12. The column 11 has several snap-fit ​​grooves 111, which are arranged sequentially in the vertical direction. The connecting plate 12 is provided with a first hook 121, which engages with the snap-fit ​​grooves 111. The first end of the first connecting rod 41 is connected to the connecting plate 12 by a first connecting rod bolt 6.

[0043] Furthermore, each of the four corners of the connecting plate 12 is provided with a first hook 121. Simply align the first hook 121 and snap it into the snap-fit ​​groove 111 to engage with the snap-fit ​​groove 111, thereby securely mounting the connecting plate 12 onto the main frame 1 and providing support for the first connecting rod 41.

[0044] The connecting plate 12 has a first connecting hole 122 and a second connecting hole 123. The snap-fit ​​groove 111 has a long strip structure and extends outward from the middle to form a round hole. The first connecting hole 122 is set corresponding to the round hole and is fixed by bolts, which further improves the connection stability between the connecting plate 12 and the main frame 1.

[0045] The second connecting hole 123 is provided corresponding to the first through hole A411 at the first end of the first connecting rod 41. After the smooth section of the first connecting rod bolt 6 passes through the first through hole A411 and the second connecting hole 123, its threaded section is screwed to the nut, so that the first connecting rod 41 can rotate relative to the connecting plate 12 around the central axis of the first connecting rod bolt 6.

[0046] A support plate 13 is provided on the top of the connecting plate 12 to support the first tabletop 2. A third connecting hole 131 is provided on the support plate 13, and a fourth connecting hole 21 is provided on the first tabletop 2. The third connecting hole 131 and the fourth connecting hole 21 are provided correspondingly and are fixed by bolts.

[0047] As an optional implementation, such as Figure 3 As shown, the second end of the first link 41 is connected to the first end of the second link 42 via the second link bolt 7.

[0048] After the smooth section of the second connecting rod bolt 7 passes through the first through hole B412 at the second end of the first connecting rod 41 and the second through hole A421 at the first end of the second connecting rod 42, its threaded section is screwed into the nut, so that the second connecting rod 42 can rotate relative to the first connecting rod 41 around the central axis of the second connecting rod bolt 7.

[0049] By adjusting the tightness of the second connecting rod bolt 7 and the nut, the relative positions of the first connecting rod 41 and the second connecting rod 42 are locked. That is... Figure 2 As shown, when the second tabletop 3 is switched to the unfolded state, the first limiting block 413 abuts against the second limiting block 423. By tightening the nut of the third connecting rod bolt 8, the relative positions of the first connecting rod 41 and the second connecting rod 42 are locked, that is, the two are in the collinear position of the central axis.

[0050] As an optional implementation, such as Figure 3As shown, a first limiting block 413 is provided on the second end of the first connecting rod 41, and a second limiting block 423 is provided on the first end of the second connecting rod 42. When the second table board 3 is in the unfolded state, the first limiting block 413 and the second limiting block 423 abut against each other.

[0051] This design effectively prevents the second tabletop 3 from being over-extended.

[0052] As an optional implementation, such as Figure 3 , Figure 4 , Figure 5 As shown, a connecting seat 31 is provided on the lower surface of the second desktop, and the second end of the second connecting rod 42 is connected to the connecting seat 31 by the third connecting rod bolt 8.

[0053] Furthermore, after the smooth section of the third link bolt 8 passes through the second through hole B422 at the second end of the second link 42 and the fifth connecting hole of the connecting seat 31, its threaded section is screwed with the nut, so that when the second table plate 3 is unfolded or folded, it can rotate relative to the second link 42 around the central axis of the third link bolt 8.

[0054] It should be noted that the first connecting rod bolt 6, the second connecting rod bolt 7, and the third connecting rod bolt 8 are all conventional connecting rod bolts with smooth sections and threaded sections. The smooth section passes through the through hole of the component that needs to be rotated to realize the relative rotation between the two connected components, while the threaded section cooperates with the nut, and the relative position of the two connected components can be locked by tightening the nut.

[0055] As an optional implementation, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, it also includes a bookshelf partition 9, which is detachably mounted on the main frame 1 for storing books.

[0056] As an optional implementation, such as Figure 4 , Figure 5 As shown, a second hook 91 is provided on the side plate of the bookshelf partition 9, and the second hook 91 engages with the locking groove 111.

[0057] Furthermore, the bookshelf partition 9 has a U-shaped cross-section, and a second hook 91 is provided at each of the four corners of its side panel.

[0058] Simply align the second hook 91 and snap it into the snap-fit ​​groove 111 to make the second hook 91 engage with the snap-fit ​​groove 111, so that the bookshelf partition 9 is securely installed on the main frame 1, improving its practicality.

[0059] There are multiple bookshelf shelves 9, and the specific number can be set according to usage needs.

[0060] As an optional implementation, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, it also includes a perforated board 10, which is set on the first tabletop 2 and is detachably connected to the main frame 1.

[0061] The pegboard 10 further enhances the functionality of the desk, providing users with space to hang items and improving space utilization.

[0062] As an optional implementation, such as Figure 4 , Figure 5 As shown, a third hook 101 is provided on the perforated plate 10, and the third hook 101 engages with the locking groove 111.

[0063] Furthermore, the perforated panel 10 has a U-shaped plate structure and a third hook 101 is provided on the outer side. Simply align the third hook 101 and snap it into the snap-fit ​​groove 111. The third hook 101 engages with the snap-fit ​​groove 111 to securely install the perforated panel 10 onto the main frame 1.
