Description

Technical Field

[0001] This application relates to the technical field of furniture structures, and in particular to an adjustable bookshelf. Background Technology

[0002] Bookshelves are a type of storage and display furniture widely used in homes and offices. Currently, the mainstream structure of bookshelves on the market is mostly composed of an external frame combined with multiple layers of support panels. Among them, the support panels are generally arranged horizontally, and books can usually only be stored upright or stacked horizontally in conventional ways.

[0003] In actual use, some books (such as magazines and newspapers) need to be tilted to display their cover content. However, the horizontal support plates of existing bookshelves are usually difficult to adapt to the above placement conditions, so there is room for improvement. Summary of the Invention

[0004] To accommodate different book placement angles and improve the versatility and display effect of the bookshelf, this application provides an adjustable bookshelf.

[0005] This application provides an adjustable bookshelf, which adopts the following technical solution: An adjustable bookshelf includes a support frame and several placement sections; The support frame includes a first frame and a second frame arranged vertically, the first frame and the second frame being arranged opposite to each other, and the first frame and the second frame being connected by a plurality of telescopic rods, the length of which is adjustable; Several placement parts are arranged from top to bottom on the support frame; each placement part includes a support plate, with a hinged side and a movable side on both sides along the width direction. The hinged side of the support plate is hinged to the first frame, and a connecting rod is provided on the movable side of the support plate. The axial direction of the connecting rod is parallel to the hinge axis of the hinged side of the support plate. The second frame has a vertically arranged first elongated adjustment hole corresponding to the connecting rod, and the connecting rod passes through the first elongated adjustment hole.

[0006] By adopting the above technical solution, books that can be stored upright or stacked horizontally can be placed on horizontally positioned support plates during daily use. When books need to be placed at an angle, the distance between the first and second frames can be adjusted by using a telescopic rod, and the support plate can be swung downwards through the connecting rod on the hinged side of the support plate and the movable side until the support plate is adjusted to an angled state. This allows the bookshelf to be placed at an angle, making it more adaptable to the different angle requirements of books and effectively improving the versatility of the bookshelf.

[0007] Preferably, the first frame includes two vertically arranged first support rods; The second frame includes two vertically arranged second support rods; The two first support rods correspond to the two second support rods respectively; The hinged side of the support plate is located between the two first support rods; and both ends of the hinged side of the support plate are respectively hinged to the two first support rods. The movable side of the support plate is located between two second support rods; there are two connecting rods, and the two connecting rods are respectively located at both ends of the movable side of the support plate; the first elongated adjustment holes are distributed on the two second support rods, and the connecting rods pass through the corresponding first elongated adjustment holes.

[0008] By adopting the above technical solution, the support plate is supported and limited by two first support rods and two second support rods, which helps to improve the structural stability of the support plate in horizontal and inclined states, and thus helps to make the support plate stable for placing books.

[0009] Preferably, the connecting rod is also threaded with a locking nut, which is abutted against the side of the second support rod opposite to the support plate.

[0010] By adopting the above technical solution, after the support plate is placed at the correct angle, the locking nut sleeved on the connecting rod can be tightened so that the locking nut is pressed against the outer side of the second support rod. The locking nut, in conjunction with the second support rod, supports and limits the support plate, which helps to improve the overall structural stability of the support plate.

[0011] Preferably, the telescopic rod is located between the corresponding first support rod and the second support rod; the telescopic rod includes a sleeve and an insert rod, the insert rod is slidably inserted into the end of the sleeve, and the insert rod and the sleeve are respectively connected to the first support rod and the second support rod at opposite ends; a limiting stud is also threaded through the outside of the sleeve, and the limiting stud abuts against the insert rod.

[0012] By adopting the above technical solution, when adjusting the distance between the first frame and the second frame, the locking of the insert rod can be released by loosening the limiting stud on the sleeve. The total length of the telescopic rod can be adjusted by extending and retracting the insert rod located in the sleeve, thereby realizing the adjustment of the distance between the first frame and the second frame. This facilitates the swing adjustment of the support plate to the required angle. After the angle of the support plate is adjusted, the extension and retraction of the telescopic rod can be restricted by tightening the limiting stud. This helps to limit the situation where the first frame and the second frame move relative to each other due to the influence of external forces, which would cause the swing angle of the support plate to change.

[0013] Preferably, the upper surface of the support plate is further provided with an extension plate, the extension plate being slidably connected to the support plate along the width direction of the support plate, and a limit stop is vertically provided on the side of the extension plate near the movable side of the support plate.

[0014] By adopting the above technical solution, when it is necessary to place books with a large width, an extension plate can be pulled outward along the width direction of the support plate to increase the overall placement area of ​​the placement section, making it easier for the placement section to better place and store books, and improving the applicability of the placement section to different books.

[0015] Preferably, the bottom of the extension plate is provided with a plurality of adjusting rods, and the support plate is provided with a plurality of second elongated adjusting holes corresponding to the adjusting rods. The adjusting rods are inserted through the corresponding second elongated adjusting holes, and the bottom end of the adjusting rods is threaded with a limit nut. The limit nut is abutted against the bottom side of the support plate.

[0016] By adopting the above technical solution, on the one hand, the extension plate can be stably slidably connected to the support plate; on the other hand, when the extension plate slides into place, the limiting nut located at the bottom of the adjusting rod can be tightened so that the limiting nut abuts against the bottom surface of the support plate to restrict the sliding of the extension plate, which is beneficial to improving the structural stability of the placement part.

[0017] Preferably, both the first support rod and the second support rod are formed by splicing together several support rods. The top end of each support rod has a connecting protrusion, and the bottom end of each support rod has a connecting hole for inserting the connecting protrusion. Adjacent support rods are connected to each other by inserting the connecting protrusion at one end into the connecting hole.

[0018] By adopting the above technical solution and increasing or decreasing the number of support rods, the overall height of the first and second frames can be adjusted, which helps to improve the applicability of the bookshelf.

[0019] Preferably, a locking bolt is provided on the outer side of the bottom end of the support rod, and the locking bolt passes through the connection between the support rod and the connecting protrusion.

[0020] By adopting the above technical solution, after the adjacent support rods are plugged in, the support rods and the connecting protrusions are further connected by locking bolts to restrict the movement of adjacent support rods, which helps to improve the structural stability of both the first frame and the second frame.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When books need to be placed at an angle, the distance between the first and second frames can be adjusted by telescopic rods, and the support plate located between the first and second frames can be swung to an angled state. This allows the bookshelf to be placed at an angle to accommodate different book placement angles.

[0022] 2. By setting the locking nut at the end of the connecting rod, after the angle of the support plate is adjusted, the locking nut can be tightened to make it press against the outside of the second support rod. The second support rod, together with the locking nut, provides auxiliary support and fixation for the support plate, which helps to improve the structural stability of the support plate.

[0023] 3. With the extension panel, when larger books need to be placed, the placement area can be temporarily increased by sliding the extension panel, making it easier to accommodate larger books and improving the applicability of the bookshelf. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] This application discloses an adjustable bookshelf, as shown in the embodiments below. Figure 1 and Figure 2It includes a support frame 1 and several placement parts 2. The placement parts 2 are used to place and display books. The several placement parts 2 are arranged from top to bottom on the support frame 1.

[0033] Reference Figure 1 and Figure 2 The support frame 1 includes a first frame 11 and a second frame 12 arranged vertically, with the first frame 11 and the second frame 12 positioned opposite each other. The first frame 11 and the second frame 12 are connected by a number of telescopic rods 3.

[0034] Reference Figure 1 and Figure 2 The first frame 11 includes two vertically arranged first support rods 111 and two horizontally arranged first transverse rods 13. The two first transverse rods 13 are located at the top and bottom of the first support rods 111 respectively, and the two ends of the first transverse rods 13 are connected to the two first support rods 111 respectively by bolts.

[0035] Reference Figure 1 and Figure 2 The second frame 12 includes two vertically arranged second support rods 121 and two horizontally arranged second transverse rods 14. The two second transverse rods 14 are located at the top and bottom of the second support rods 121 respectively, and the two ends of the second transverse rods 14 are connected to the two second support rods 121 respectively by bolts.

[0036] Reference Figure 2 and Figure 3 Both the first support rod 111 and the second support rod 121 are formed by splicing together several support rods 10. Each support rod 10 has a connecting protrusion 101 at its top and a connecting hole at its bottom for inserting the connecting protrusion 101. Adjacent support rods 10 are connected to each other via connecting protrusions 101 at their closest ends. A locking bolt is threaded through the outer side of the bottom end of each support rod 10, inserting into the connecting hole and abutting against the connecting protrusion 101. This restricts relative movement of adjacent support rods 10 and improves the connection stability of adjacent support rods 10. In actual use, the height of the first frame 11 and the second frame 12 can be adjusted by increasing or decreasing the number of support rods 10 as needed.

[0037] Reference Figure 2 and Figure 4Two first support rods 111 correspond to two second support rods 121, and telescopic rods 3 are evenly distributed between the corresponding first support rods 111 and second support rods 121. Specifically, the telescopic rod 3 includes a sleeve 31 and an insert rod 32. The insert rod 32 is slidably inserted into the end of the sleeve 31. The ends of the insert rod 32 and the sleeve 31 that are far apart from each other are respectively connected to connecting seats 30. The connecting seats 30 at the ends of the insert rod 32 and the sleeve 31 that are far apart from each other are respectively connected to the side of the corresponding first support rod 111 and second support rod 121 by bolts, so as to realize the stable connection of the two ends of the telescopic rod 3 to the first support rod 111 and the second support rod 121.

[0038] Reference Figure 2 and Figure 4 The sleeve 31 is also threaded with a limiting stud 33, which is located at the end of the sleeve 31 near the insertion rod 32. The limiting stud 33 passes through the inner cavity of the sleeve 31 and abuts against the insertion rod 32 to restrict the sliding of the insertion rod 32. In this embodiment, the stud is a conventional internal hexagonal stud so that it can be rotated by an internal hexagonal wrench.

[0039] Reference Figure 2 and Figure 4 When it is necessary to adjust the distance between the first frame 11 and the second frame 12, loosen the limiting stud 33 so that the insertion rod 32 can slide within the sleeve 31, thereby adjusting the total length of the telescopic rod 3 and realizing the adjustment of the distance between the first frame 11 and the second frame 12. After the adjustment is completed, tighten the limiting stud 33 to restrict the extension and retraction of the telescopic rod 3 and ensure the stability of the bookshelf structure.

[0040] Reference Figure 2 and Figure 5 The placement part 2 includes a support plate 21 and an extension plate 22. The two sides of the support plate 21 along the width direction are a hinge side and a movable side, respectively. The hinge side of the support plate 21 is located between two first support rods 111. Two mounting holes are opened at both ends of the hinge side of the support plate 21. A connecting pin 112 is threaded through the mounting hole at each of the two first support rods 111. The connecting pin 112 is inserted into the corresponding mounting hole to realize the hinge side of the support plate 21 being stably hinged to the two first support rods 111.

[0041] Reference Figure 2 and Figure 5The movable side of the support plate 21 is located between two second support rods 121. Each end of the movable side is provided with a connecting rod 211, one end of which is threaded to the end of the movable side of the support plate 21, enabling a detachable connection between the connecting rod 211 and the support plate 21. The axial direction of the connecting rod 211 is parallel to the hinge axis of the hinged side of the support plate 21. Each of the two second support rods 121 of the second frame 12 has a vertically arranged first elongated adjustment hole 122 corresponding to the connecting rod 211. The connecting rods 211 at both ends of the movable side of the support plate 21 pass through the corresponding first elongated adjustment holes 122 of the two second support rods 121.

[0042] Reference Figure 2 and Figure 6 When books need to be placed at an angle, the distance between the first frame 11 and the second frame 12 is adjusted by the telescopic rod 3, and the support plate 21 is swung downward by the connecting rod 211, which is inserted into the first long strip adjustment hole 122 on the hinge side of the support plate 21, until the support plate 21 is adjusted to an angled state so that books can be placed at an angle through the support plate 21.

[0043] Reference Figure 2 and Figure 6 The end of the connecting rod 211 away from the support plate 21 is also threaded with a locking nut, which is pressed against the side of the second support rod 121 away from the support plate 21. After the angle of the support plate 21 is adjusted to the correct position, the locking nut is tightened so that it presses against the outer side of the second support rod 121. The locking nut, in conjunction with the second support rod 121, supports and limits the support plate 21, thereby helping to restrict the swing of the support plate 21 and improving the overall structural stability of the support plate 21.

[0044] Reference Figure 2 and Figure 5 The extension plate 22 is located on the upper surface of the support plate 21 and is slidably connected to the support plate 21 along the width direction of the support plate 21. When it is necessary to place books with a large width, the extension plate 22 can be pulled outward along the width direction of the support plate 21 to increase the overall support area of ​​the placement part 2, thereby making it easier for the placement part 2 to better place and store books.

[0045] Reference Figure 2 and Figure 5Specifically, the extension plate 22 has two adjusting rods 221 protruding from its bottom along its length. The support plate 21 has two second elongated adjusting holes 212 corresponding to the two adjusting rods 221. The length direction of the second elongated adjusting holes 212 is parallel to the width direction of the support plate 21. The adjusting rods 221 pass through the corresponding second elongated adjusting holes 212 and extend out of the bottom side of the support plate 21. The bottom end of the adjusting rod 221 is threaded with a limit nut via an external thread structure, and the limit nut is pressed against the bottom side of the support plate 21. When the extension plate 22 slides to its position, tightening the limit nut causes it to press against the bottom surface of the support plate 21, thus restricting the extension plate 22 from sliding. This helps to limit the movement of the extension plate 22 due to external force when books are placed in the placement part 2. Simultaneously, it allows the extension plate 22 to be adjusted to any desired position when the support plate 21 is tilted, thus preventing the extension plate 22 from sliding downwards to its maximum travel due to its own weight.

[0046] Reference Figure 2 and Figure 5 A limiting stop 23 is vertically provided on the movable side of the extension plate 22 near the support plate 21. The limiting stop 23 is used to prevent books from sliding out of the extension plate 22 when placed on the inclined placement part 2, which helps to make the books more stably placed on the inclined placement part 2.

[0047] The implementation principle of this application embodiment is as follows: In normal use, stackable books are placed on the horizontally positioned storage section 2.

[0048] When books need to be placed at an angle, the distance between the first frame 11 and the second frame 12 can be adjusted by the telescopic rod 3 between the first frame 11 and the second frame 12, and the support plate 21 of each placement part 2 can be swung to an inclined state. This allows the books to be placed at an angle by means of the support plate 21, thus adapting to the placement angle requirements of different books and effectively improving the versatility of the bookshelf.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
