Technical Field
[0001] This utility model relates to the field of bookshelf technology, and in particular to a bookshelf device with adjustable shelf height. Background Technology
[0002] A bookshelf is a piece of furniture used to store books. It is typically made of materials such as wood, metal, or plastic, and is designed with multiple shelves for easy categorization and access. Its main function is to organize and store books, keeping the reading space neat and tidy, while also showcasing a person's personal book collection. Bookshelves come in various styles, including floor-standing, wall-mounted, and rotating models, and their size and design can be customized to meet specific space needs. They are commonly found in homes, libraries, and offices.
[0003] In the current technology, the height of most bookshelves cannot be adjusted. Since different books are of different sizes, some larger books cannot be placed upright in the bookshelf, while some smaller books cannot make full use of the space between the shelves, making the bookshelf inconvenient to use. Utility Model Content
[0004] The purpose of this invention is to solve the problem that in the existing technology, the height of most bookshelves cannot be adjusted. Because different books are of different sizes, some larger books cannot be placed upright in the bookshelf, while some smaller books cannot be placed in the bookshelf and the space between the shelves cannot be fully utilized, resulting in the inconvenience of using the bookshelf.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bookshelf device with adjustable shelf height, comprising: a bookshelf outer frame, and further comprising:
[0006] Multiple slots are equidistantly located on opposite sides of the inner wall of the bookshelf's outer frame. Each slot has a first insertion hole and a second insertion hole on one side of its inner wall. The slots are grouped in pairs. Multiple groups of slots have partitions slidably connected to their inner walls. Each partition has a first and a second circular hole on its opposite side. The outer surface of the first circular hole is slidably connected to the inside of the first insertion hole, and the outer surface of the second circular hole is slidably connected to the inside of the second insertion hole. Springs are installed inside both the first and second circular holes. One end of each spring is fixedly connected to one side of the first and second circular holes, respectively, and the other end of each spring is fixedly connected to the inside of the first and second insertion holes, respectively.
[0007] Preferably, the bottom of the partition is provided with a plurality of sliding grooves, wherein two of the sliding grooves are respectively connected to two insertion holes one, and the other two sliding grooves are respectively connected to two insertion holes two, wherein the diameter of the insertion holes two is larger than the diameter of the insertion holes one.
[0008] Preferably, the inner walls of the two grooves are slidably connected with U-shaped strips, which are fixedly connected to the first and second insertion rods respectively, and a handle is fixedly connected to one side of the U-shaped strips.
[0009] Preferably, one side of the slot is provided with a bevel, one end of the second insertion rod is provided with a bevel, the diameter of the second insertion rod is larger than that of the first insertion rod, the first insertion rod is adapted to the first insertion hole, and the second insertion rod is adapted to the second insertion hole.
[0010] Preferably, a placement frame is fixedly connected to the top of the partition, and the bottom of the inner wall of the placement frame is inclined.
[0011] Preferably, on opposite sides of the bookshelf outer frame, multiple fixing plates are symmetrically and equidistantly fixedly connected in pairs. One side of each fixing plate is rotatably connected to a round rod, and one end of each of the two round rods is fixedly connected to a side frame.
[0012] Preferably, the outer surface of the fixing plate is provided with an arc-shaped groove, and a round rod two is fixedly connected to each opposite side of the side frame, and the outer surface of the round rod two is slidably connected to the inside of the arc-shaped groove.
[0013] Preferably, magnet 1 is fixedly connected to each opposite side of the side frame, and multiple magnet 2 are fixedly connected to each opposite side of the bookshelf outer frame in pairs at equal intervals, and magnet 1 and magnet 2 are magnetically attracted to each other.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] This invention involves inserting a fingertip into the handle and pulling the handle inwards. This causes the U-shaped strip to slide inwards along the inside of the groove, simultaneously causing the first and second insertion rods to slide inwards along the first and second circular holes, respectively. This disengages the first and second insertion rods from the inside of the first and second insertion holes, respectively, and simultaneously compresses the spring. This releases the fixing of the partition and the placement frame, allowing the partition to slide out of the slot and insert into another slot. The inclined surface of the second insertion rod then contacts the inclined surface of the slot and is subjected to a compressive force, causing the second insertion rod to slide inwards into the second circular hole. Simultaneously, this causes the U-shaped strip to slide inwards along the inside of the groove. The sliding mechanism simultaneously drives the first insertion rod to slide into the first round hole, compressing the spring. When the second insertion rod slides to the second insertion hole, the first insertion rod is positioned in the first insertion hole. Under the restoring force of the spring, the first and second insertion rods can be inserted into the first and second insertion holes respectively, limiting the position of the partition and the placement frame. This allows for easy adjustment of the position of the partition and the placement frame, facilitating the appropriate adjustment of the distance between two adjacent placement frames according to the size of different books. This makes it convenient to place books of different sizes in the placement frames, making full use of the space between the bookshelf partitions and improving the convenience of using the bookshelf.
[0016] This invention unfolds the side frame by pulling it downwards and rotating it downwards with the help of a first round rod. Simultaneously, the second round rod slides downwards along the inside of the arc-shaped groove, allowing the side frame to unfold for easy placement of other books. At the same time, it separates magnets one and two. Conversely, by rotating the side frame upwards, the magnetic attraction between magnets one and two allows the side frame to remain relatively fixed when they are attracted together, thus enabling it to be stored. When the side frame is unfolded, it is convenient to place books, increasing the book capacity of the bookshelf. When the side frame is stored, it reduces the overall space occupied by the bookshelf.
[0017] In this invention, when the side frame is unfolded, i.e., the round rod slides to the lowest position of the arc groove, the side frame has a certain degree of inclination, and at the same time, the bottom of the inner wall of the placement frame has a certain degree of inclination. In this way, when books are placed in the side frame and the placement frame, the bookshelf can be prevented from falling when it shakes to a certain extent. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0026] Examples, such as Figure 1-4 As shown, this utility model provides a height-adjustable bookshelf device, including: a bookshelf outer frame 1, and further including: multiple slots 103, which are equidistantly opened on opposite sides of the inner wall of the bookshelf outer frame 1. One side of the inner wall of each slot 103 is provided with a first insertion hole and a second insertion hole. The multiple slots 103 are evenly divided into groups of two. The inner walls of the multiple groups of slots 103 are slidably connected to partitions 101. The opposite sides of each partition 101 are provided with a first circular hole 104 and a second circular hole 105. The outer surface of the first circular hole 104 is slidably connected to the inside of the first insertion hole, and the outer surface of the second circular hole 105 is slidably connected to the inside of the second insertion hole. Springs 109 are provided inside both the first circular hole 104 and the second circular hole 105. One end of each spring 109 is fixedly connected to one side of the first circular hole 104 and the second circular hole 105, and the other end of each spring 109 is fixedly connected to the inside of the first insertion hole and the second insertion hole.
[0027] Furthermore, such as Figure 1-4 As shown, the bottom of the partition 101 is provided with multiple sliding grooves 106, two of which are connected to two sockets 1 respectively, and the other two sliding grooves 106 are connected to two sockets 2 respectively. The diameter of the sockets 2 is larger than that of the sockets 1. The above arrangement facilitates operation.
[0028] Furthermore, such as Figure 1-4 As shown, U-shaped strips 110 are slidably connected to the inner walls of the two grooves 106. The U-shaped strips 110 are fixedly connected to the first insertion rod 107 and the second insertion rod 108, respectively. A handle 111 is fixedly connected to one side of the U-shaped strip 110. By inserting the tip of a finger into the handle 111 and pulling the handle 111 towards the middle, the U-shaped strip 110 is moved to slide towards the middle along the inside of the groove 106, and the first insertion rod 107 and the second insertion rod 108 are moved inward along the first round hole 104 and the second round hole 105, respectively.
[0029] Furthermore, such as Figure 1-4 As shown, one side of the slot 103 is provided with a bevel, and one end of the insertion rod 108 is provided with a bevel. The diameter of the insertion rod 108 is larger than that of the insertion rod 107. The insertion rod 107 is adapted to the insertion hole 1, and the insertion rod 108 is adapted to the insertion hole 2. With the above arrangement, when the bevel of the insertion rod 108 contacts the bevel of the slot 103, it will be subjected to a squeezing force, causing the insertion rod 108 to slide into the inner part of the circular hole 105. The insertion rod 108 cannot be inserted into the insertion hole 1, but can only be inserted into the insertion hole 2.
[0030] Furthermore, such as Figure 1-4 As shown, a placement frame 102 is fixedly connected to the top of the partition 101. The bottom of the inner wall of the placement frame 102 is set in an inclined shape. With the above setting, books can be placed in the placement frame 102 and the books can be kept at a certain inclination. When the bookshelf shakes, the books will fall.
[0031] Furthermore, such as Figure 1-4 As shown, on each of the opposite sides of the bookshelf outer frame 1, multiple fixing plates 201 are symmetrically and equidistantly fixed. One side of each fixing plate 201 is rotatably connected to a round rod 203. One end of each round rod 203 is fixedly connected to a side frame 2. With the above arrangement, the side frame 2 can be rotated at an appropriate angle with the cooperation of the round rod 203.
[0032] Furthermore, such as Figure 1-4 As shown, the outer surface of the fixed plate 201 is provided with an arc-shaped groove 202. A round rod 204 is fixedly connected to the opposite side of the side frame 2. The outer surface of the round rod 204 is slidably connected to the inside of the arc-shaped groove 202. With the above arrangement, the center of the arc-shaped groove 202 coincides with the center of the round rod 203. When the side frame 2 drives the round rod 203 to rotate, the round rod 204 can slide along the inside of the arc-shaped groove 202. When it slides to the lowest position, the side frame 2 can be unfolded and maintain a certain tilt angle.
[0033] Furthermore, such as Figure 1-4 As shown, magnet 205 is fixedly connected to the opposite side of the side frame 2, and multiple magnets 206 are fixedly connected symmetrically and equidistantly to the opposite side of the bookshelf outer frame 1. Magnets 205 and 206 are magnetically attracted to each other. Under the magnetic attraction of magnets 205 and 206, when magnets 205 and 206 are attracted together, the side frame 2 can be kept in a relatively fixed state, and the side frame 2 can be stored.
[0034] Working principle: In use, when it is necessary to adjust the distance between the two partitions 101, insert the tip of your finger into the handle 111 and pull the handle 111 towards the center. This causes the U-shaped strip 110 to slide towards the center along the inside of the slide groove 106. Simultaneously, this causes the first insertion rod 107 and the second insertion rod 108 to slide inward along the first and second round holes 104 and 105 respectively. This causes the first insertion rod 107 and the second insertion rod 108 to disengage from the inside of the first and second insertion holes respectively. At the same time, the spring 109 is compressed. This releases the fixing of the partition 101 and the placement frame 102, allowing the partition 101 to slide out of the slot 103 and insert into the other slot 10. Inside the slot 103, the inclined surface of the second insertion rod 108 contacts the inclined surface of the slot 103 and is subjected to a compressive force, causing the second insertion rod 108 to slide into the second round hole 105. Simultaneously, this drives the U-shaped strip 110 to slide towards the center along the inside of the slide groove 106, and simultaneously drives the first insertion rod 107 to slide into the first round hole 104. Simultaneously, the spring 109 is compressed. When the second insertion rod 108 slides to the second insertion hole position, the first insertion rod 107 is at the first insertion hole position. Under the restoring force of the spring 109, the first insertion rod 107 and the second insertion rod 108 can be inserted into the first and second insertion holes respectively, limiting the position of the partition 101 and the placement frame 102. The position of the partition 101 and the placement frame 102 can be easily adjusted, allowing for appropriate adjustment of the distance between two adjacent placement frames 102 according to the size of different books. This facilitates the placement of books of different sizes in the placement frames 102, making full use of the space between the bookshelf partitions 101 and improving the convenience of using the bookshelf. By pulling the side frame 2 downwards and rotating it downwards with the cooperation of the first round rod 203, the second round rod 204 is simultaneously driven to slide downwards along the inside of the arc groove 202, unfolding the side frame 2 for easy placement of other books. At the same time, it separates the first magnet 205 and the second magnet 206. Conversely, by rotating the side frame 2 upwards, the distance between adjacent placement frames 102 and the second round rod 206 can be adjusted. Under the magnetic attraction of magnet 206, when magnet 205 and magnet 206 are attracted together, the side frame 2 can be kept in a relatively fixed state and stored. When the side frame 2 is unfolded, it is convenient to place books and increase the number of books that can be placed on the bookshelf. When the side frame 2 is stored, it can reduce the space occupied by the bookshelf as a whole. When the side frame 2 is unfolded, that is, when the round rod 204 slides to the bottom position of the arc groove 202, the side frame 2 has a certain degree of inclination. At the same time, the bottom of the inner wall of the placement frame 102 also has a certain degree of inclination. When books are placed in the side frame 2 and the placement frame 102, when the bookshelf shakes to a certain extent, it can prevent the books from falling.
[0035] 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.
