Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 An adjustable bookshelf includes a first baffle 1 and a second baffle 2. Two support parts 3 are installed at the bottom of the second baffle 2. A base plate 4 is installed on the side of the second baffle 2 near the first baffle 1. A device plate 6 is provided on the base plate 4. The device plate 6 is installed on the side of the first baffle 1 near the second baffle 2. A servo motor 7 is installed on the device plate 6. A transmission gear 8 is installed on the output shaft of the servo motor 7. A rack 9 meshes with the transmission gear 8. A connecting block 10 is provided between the rack 9 and the base plate 4 to connect the two.

[0023] When there are too many books and the bookshelf needs to be adjusted to meet storage requirements, the user turns on the servo motor 7. The rotation of the servo motor 7 drives the transmission gear 8 to rotate synchronously, causing the rack 9, which meshes with the transmission gear 8, to move in a direction away from the first baffle 1. When the rack 9 moves, it drives the connecting block 10 installed on it to move synchronously, which in turn drives the base plate 4 connected to the connecting block 10 to move in a direction away from the first baffle 1. When the base plate 4 moves, it always remains in contact with the device plate 6. When it moves to an appropriate distance, the servo motor 7 is turned off, thereby releasing the movement of the base plate 4, achieving the purpose of stretching the bookshelf, so that the bookshelf can store more books, thereby improving the practicality and flexibility of the bookshelf.

[0024] Specifically, in this embodiment, the device plate 6 is provided with a rotating groove 11. The size of the rotating groove 11 is larger than the size of the transmission gear 8, and the transmission gear 8 is rotatably adapted to the rotating groove 11, so that the transmission gear 8 can be rotatably mounted on the device plate 6 through the rotating groove 11. At the same time, the setting of the rotating groove 11 allows the transmission gear 8 to maintain a normal rotation state.

[0025] Specifically, in this embodiment, a movable groove 12 is provided on the device plate 6. The movable groove 12 runs through the entire device plate 6 and is connected to the rotating groove 11. The rack 9 is slidably adapted in the movable groove 12. The movable groove 12 provides space for the installation of the rack 9 and effectively ensures the movable distance of the rack 9 on the device plate 6, so that the rack 9 is not restricted by the device plate 6 when it moves.

[0026] Specifically, in this embodiment, the device plate 6 is provided with a sliding groove 13, which is adapted to the connecting block 10, so that the connecting block 10 can pass through the device plate 6 and connect with the base plate 4 through the sliding groove 13, thereby achieving the purpose of moving the base plate 4 through the connecting block 10.

[0027] Specifically, in this embodiment, a first connecting plate 14 is installed on the wall of the rotating slot 11. A rotating hole 15 is provided on the first connecting plate 14. The servo motor 7 is installed on the side wall of the first connecting plate 14 away from the transmission gear 8, so that the servo motor 7 can be installed on the bookshelf through the first connecting plate 14. The output shaft of the servo motor 7 can pass through the rotating hole 15 through the first connecting plate 14 and connect with the transmission gear 8, thereby driving the transmission gear 8 to rotate.

[0028] Specifically, in this embodiment, two second connecting plates 16 are installed at the bottom of the device plate 6. The two second connecting plates 16 are located on both sides of the device plate 6. The end of the second connecting plate 16 away from the device plate 6 is in contact with the base plate 4, and the height of the second connecting plate 16 is higher than the height of the servo motor 7, so that a receiving space can be formed between the second connecting plate 16 and the first baffle 1 and the second baffle 2. The servo motor 7 is placed in the receiving space, thereby facilitating the installation of the servo motor 7.

[0029] Specifically, in this embodiment, an L-shaped connecting plate 17 is installed on the first baffle 1. The end of the L-shaped baffle 17 away from the first baffle 1 is installed on the device plate 6. Several U-shaped connecting plates 18 are installed opposite each other at positions above the L-shaped connecting plate 17 on the first baffle 1 and the second baffle 2. Several adjacent U-shaped connecting plates 18 are in contact with each other. The U-shaped connecting plates 18 close to the L-shaped connecting plate 17 are in contact with each other, so that when the base plate 4 moves, it can drive several U-shaped connecting plates 18 installed on the second baffle 2 to move synchronously, so that books can be placed in the space inside the U-shaped connecting plate 18 and on its top wall, further expanding the storage space on the bookshelf.

[0030] When there are too many books and the bookshelf needs to be adjusted to meet storage requirements, the user turns on the servo motor 7. The rotation of the servo motor 7 drives the transmission gear 8 to rotate synchronously, causing the rack 9, which meshes with the transmission gear 8, to move in a direction away from the first baffle 1. When the rack 9 moves, it drives the connecting block 10 installed on it to move synchronously, which in turn drives the base plate 4 connected to the connecting block 10 to move in a direction away from the first baffle 1. When the base plate 4 moves, it always remains in contact with the device plate 6. When it moves to an appropriate distance, the servo motor 7 is turned off, thereby releasing the movement of the base plate 4, achieving the purpose of stretching the bookshelf, so that the bookshelf can store more books, thereby improving the practicality and flexibility of the bookshelf.

[0031] Specifically, in this embodiment, the device plate 6 is provided with a rotating groove 11. The size of the rotating groove 11 is larger than the size of the transmission gear 8, and the transmission gear 8 is rotatably adapted to the rotating groove 11, so that the transmission gear 8 can be rotatably mounted on the device plate 6 through the rotating groove 11. At the same time, the setting of the rotating groove 11 allows the transmission gear 8 to maintain a normal rotation state.

[0032] Specifically, in this embodiment, a movable groove 12 is provided on the device plate 6. The movable groove 12 runs through the entire device plate 6 and is connected to the rotating groove 11. The rack 9 is slidably adapted in the movable groove 12. The movable groove 12 provides space for the installation of the rack 9 and effectively ensures the movable distance of the rack 9 on the device plate 6, so that the rack 9 is not restricted by the device plate 6 when it moves.

[0033] Specifically, in this embodiment, the device plate 6 is provided with a sliding groove 13, which is adapted to the connecting block 10, so that the connecting block 10 can pass through the device plate 6 and connect with the base plate 4 through the sliding groove 13, thereby achieving the purpose of moving the base plate 4 through the connecting block 10.

[0034] Specifically, in this embodiment, a first connecting plate 14 is installed on the wall of the rotating slot 11. A rotating hole 15 is provided on the first connecting plate 14. The servo motor 7 is installed on the side wall of the first connecting plate 14 away from the transmission gear 8, so that the servo motor 7 can be installed on the bookshelf through the first connecting plate 14. The output shaft of the servo motor 7 can pass through the rotating hole 15 through the first connecting plate 14 and connect with the transmission gear 8, thereby driving the transmission gear 8 to rotate.

[0035] Specifically, in this embodiment, two second connecting plates 16 are installed at the bottom of the device plate 6. The two second connecting plates 16 are located on both sides of the device plate 6. The end of the second connecting plate 16 away from the device plate 6 is in contact with the base plate 4, and the height of the second connecting plate 16 is higher than the height of the servo motor 7, so that a receiving space can be formed between the second connecting plate 16 and the first baffle 1 and the second baffle 2. The servo motor 7 is placed in the receiving space, thereby facilitating the installation of the servo motor 7.

[0036] Specifically, in this embodiment, an L-shaped connecting plate 17 is installed on the first baffle 1. The end of the L-shaped connecting plate 17 away from the first baffle 1 is installed on the device plate 6. Several U-shaped connecting plates 18 are installed opposite each other at positions above the L-shaped connecting plate 17 on the first baffle 1 and the second baffle 2. Several adjacent U-shaped connecting plates 18 are in contact with each other, and the L-shaped connecting plate 17 is in contact with its adjacent U-shaped connecting plate 18. This allows the bottom plate 4 to move while simultaneously moving several U-shaped connecting plates 18 installed on the second baffle 2, so that books can be placed in the space inside the U-shaped connecting plate 18 and on its top wall, further expanding the storage space on the bookshelf.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto.
