Technical Field

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

[0002] Libraries are places for people to study and read, and most of the books are placed on shelves for easy access.

[0003] In the prior art, such as the bookshelf structure described in Chinese Patent CN 219422466 U, a support frame is included, with a first synchronous pulley rotatably connected to both sides of one side of the support frame. In this invention, by fixing the two sides of the two shelves to a first and a second transmission belt respectively, when the height of the shelves needs to be adjusted, simply turning the handle causes the third transmission belt to drive another third synchronous pulley to rotate, which in turn drives the second synchronous pulley to rotate. The second synchronous pulley rotates under the traction of the second transmission belt, and the first transmission belt at the other end also rotates. This allows for height adjustment of the shelves on both sides. Simultaneously, the first locking blocks on both sides of the shelves slide within their first locking slots as the shelves move, limiting their movement. This method allows users to freely adjust the height of the shelves, making them more convenient to use. However, this patent still has the following problems.

[0004] In the aforementioned patent, although the storage space of the two shelves can be functionally partitioned by setting a sliding plate on the two shelves and moving the sliding plate, and the magnetic blocks set below the sliding plate and above the shelf have opposite magnetic poles on their opposite sides, which can attract each other and prevent the sliding plate from easily shifting its position, the adjustment range is not very accurate and the application range is small because the position of the magnetic blocks on the shelf is fixed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology has low precision in adjustment range and limited application range because the position of the magnetic blocks on the shelf is fixed. Therefore, a modular bookshelf structure is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a modular bookshelf structure, including a main body, with multiple placement plates inside the main body. A vertical plate is fixedly installed on the top of each placement plate. An L-shaped groove is formed on the outer wall of the vertical plate. Multiple insert plates are slidably installed inside the L-shaped groove. A limiting groove is formed inside each insert plate. A spring is fixedly installed on the bottom surface inside the limiting groove. A limiting plate is fixedly installed on the top of the spring. A lifting block and a slider are fixedly installed on the top of the limiting plate. The tops of the lifting block and the slider both penetrate through the insert plates. A sliding plate is fixedly installed on the outer wall of each insert plate. A storage slot is formed at one end of the sliding plate. A threaded hole is formed through the inner wall of the storage slot. A first threaded rod is threadedly connected inside the threaded hole. A handle is fixedly installed at one end of the first threaded rod. A pressure plate is fixedly installed at the end of the first threaded rod away from the handle.

[0007] Preferably, the inner wall of the body is provided with a sliding groove, and multiple evenly distributed slots are provided on both sides of the sliding groove.

[0008] Preferably, a movable plate is fixedly installed on the outer wall of the placement plate. A fixed groove is opened on the side of the movable plate opposite to the placement plate. An operating groove is opened at the bottom of the placement plate. A second threaded rod is rotatably installed on the inner wall of the fixed groove. One end of the second threaded rod enters the operating groove and is fixedly installed with a handle. Two connecting plates are threadedly connected to the outer wall of the second threaded rod. A locking block is fixedly installed on the opposite side of the two connecting plates. Openings are opened through both sides of the outer side of the movable plate. The two locking blocks are slidably connected to the two openings respectively.

[0009] Preferably, the outer wall of the main body is provided with a plurality of evenly distributed guide grooves, and the outer wall of the placement plate is provided with a positioning groove.

[0010] Preferably, support frames are fixedly installed at all four corners of the bottom of the main body.

[0011] Preferably, the outer wall of the movable plate is in contact with the inner wall of the slide groove, and the outer wall of the card block is in contact with the inner wall of the card groove.

[0012] Preferably, the second threaded rod is provided with two sections of threads with opposite textures, and the second threaded rod is connected to two connecting plates respectively through the two sections of threads with opposite textures.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, during use, the operator inserts the insert plate into the L-shaped groove as needed. The inclined surface of the slider contacts the inner wall of the L-shaped groove, and the slider is squeezed into the limiting groove. The spring is compressed. When the outer wall of the insert plate contacts the inner wall of the L-shaped groove, the elastic force of the spring pushes the slider into the L-shaped groove, thus completing the installation. This allows for the installation of the corresponding number of slides as needed. When adjusting the space, the operator moves the slide to the corresponding position, rotates the handle, and the handle drives the first threaded rod to rotate. The first threaded rod moves along the threaded hole until the pressure plate contacts the upright plate. The pressure plate applies pressure to the upright plate, increasing the friction between the two and fixing the slide. This completes the adjustment and improves the adjustment range.

[0015] 2. In this utility model, when adjusting the placement plate, the operator turns the handle, the second threaded rod rotates, causing the two connecting plates to move closer to each other, the locking block leaves the slot, and then the operator moves the placement plate to the appropriate position. The operator then turns the handle in the opposite direction, the second threaded rod rotates in the opposite direction, and the locking block enters the slot. In this way, the position of the placement plate can be adjusted, making it convenient for the user to adjust the position of the placement plate according to the height of the book.

A spring 11 is fixedly installed on the bottom surface inside the limiting groove 10. A limiting plate 12 is fixedly installed on the top of the spring 11. A lifting block 13 and a slider 14 are fixedly installed on the top of the limiting plate 12. The tops of the lifting block 13 and the slider 14 both penetrate the insert plate 9. A sliding plate 7 is fixedly installed on the outer wall of the insert plate 9. A storage slot 15 is formed at one end of the sliding plate 7. A threaded hole 16 is formed through the inner wall of the storage slot 15. A first threaded rod 17 is threadedly connected inside the threaded hole 16. A handle 18 is fixedly installed at one end of the first threaded rod 17. A pressure plate 19 is fixedly installed at the end of the first threaded rod 17 away from the handle 18.

[0024] The overall effect of Embodiment 1 is as follows: During use, the operator inserts the insert plate 9 into the L-shaped groove 8 as needed. The inclined surface of the slider 14 contacts the inner wall of the L-shaped groove 8, and the slider 14 is squeezed into the limiting groove 10. The spring 11 is compressed. When the outer wall of the insert plate 9 contacts the inner wall of the L-shaped groove 8, the elastic force of the spring 11 pushes the slider 14 into the L-shaped groove 8, thus completing the installation. This facilitates the installation of the corresponding number of slide plates 7 as needed. When adjusting the space, the operator moves the slide plate 7 to the corresponding position and rotates the handle 18. The handle 18 drives the first threaded rod 17 to rotate. The first threaded rod 17 moves along the threaded hole 16 until the pressure plate 19 contacts the upright plate 6. The pressure plate 19 applies pressure to the upright plate 6, increasing the friction between the two and fixing the slide plate 7. This completes the adjustment and improves the adjustment range.

[0025] Example 2, as Figures 1-4 As shown, further, a sliding groove 20 is provided on the inner wall of the main body 1, and multiple evenly distributed slots 21 are provided on both sides of the sliding groove 20.

[0026] Furthermore, a movable plate 22 is fixedly installed on the outer wall of the placement plate 3. A fixed groove 23 is provided on the side of the movable plate 22 opposite to the placement plate 3. An operating groove 25 is provided at the bottom of the placement plate 3. A second threaded rod 26 is rotatably installed on the inner wall of the fixed groove 23. One end of the second threaded rod 26 enters the operating groove 25 and is fixedly installed with a handle 29. Two connecting plates 27 are threadedly connected to the outer wall of the second threaded rod 26. A locking block 28 is fixedly installed on the opposite side of the two connecting plates 27. Openings 24 are provided through the outer sides of the movable plate 22. The two locking blocks 28 are slidably connected to the two openings 24 respectively.

[0027] Furthermore, the outer wall of the main body 1 is provided with multiple evenly distributed guide grooves 5, and the outer wall of the placement plate 3 is provided with positioning grooves 4. When the positioning groove 4 moves to the side of the guide groove 5, the locking block 28 moves to the side of the locking groove 21.

[0028] Furthermore, support frames 2 are fixedly installed at the four corners of the bottom of the main body 1.

[0029] Furthermore, the outer wall of the movable plate 22 is in contact with the inner wall of the slide groove 20, and the outer wall of the locking block 28 is in contact with the inner wall of the slot 21. When the locking block 28 enters the slot 21, the placement plate 3 can be fixed.

[0030] Furthermore, the second threaded rod 26 is provided with two sections of threads with opposite textures. The second threaded rod 26 is connected to two connecting plates 27 respectively through the two sections of threads with opposite textures. When the second threaded rod 26 rotates, the two connecting plates 27 move closer to each other or further away from each other.

[0031] The effect achieved by the entire embodiment 2 is that when adjusting the placement plate 3, the operator turns the handle 29, the second threaded rod 26 rotates, so that the two connecting plates 27 move closer to each other, the locking block 28 leaves the slot 21, and then the operator moves the placement plate 3 to a suitable position, turns the handle 29 in the opposite direction, the second threaded rod 26 rotates in the opposite direction, and the locking block 28 enters the slot 21. In this way, the position of the placement plate 3 can be adjusted, which makes it convenient for the user to adjust the position of the placement plate 3 according to the height of the book.

[0032] Working principle: During use, the operator inserts the insert plate 9 into the L-shaped groove 8 as needed. The inclined surface of the slider 14 contacts the inner wall of the L-shaped groove 8, and the slider 14 is squeezed into the limiting groove 10. The spring 11 is compressed. When the outer wall of the insert plate 9 contacts the inner wall of the L-shaped groove 8, the elastic force of the spring 11 pushes the slider 14 into the L-shaped groove 8, thus completing the installation. This allows for the installation of the corresponding number of slide plates 7 as needed. When adjusting the space, the operator moves the slide plate 7 to the corresponding position and rotates the handle 18. The handle 18 drives the first threaded rod 17 to rotate. The first threaded rod 17 moves along the threaded hole 16 until the pressure plate 19 contacts the upright plate 6. The pressure plate 19 applies pressure to the upright plate 6, increasing the friction between the two and fixing the slide plate 7. This completes the adjustment and improves the adjustment range. When adjusting the placement plate 3, the operator turns the handle 29, the second threaded rod 26 rotates, causing the two connecting plates 27 to move closer to each other, and the locking block 28 to leave the slot 21. Then the operator moves the placement plate 3 to the appropriate position, turns the handle 29 in the opposite direction, the second threaded rod 26 rotates in the opposite direction, and the locking block 28 enters the slot 21. In this way, the position of the placement plate 3 can be adjusted, making it convenient for the user to adjust the position of the placement plate 3 according to the height of the book.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
