Description

Technical Field

[0001] This invention relates to the field of study support products, and in particular to a three-dimensional adjustable integrated study support for high school students. Background Technology

[0002] With the full implementation of the new college entrance examination reform, high school students need to frequently use various types and sizes of paper learning materials during the exam preparation stage. These include textbooks and supplementary materials of different sizes, large-format bound test papers, loose-leaf knowledge point manuals, error notebooks, and other materials. As a core auxiliary tool for standardizing reading and writing posture, relieving visual fatigue, and improving exam preparation focus and learning efficiency, the stability, ease of operation, adaptability to different scenarios, and safety of use of book stands directly affect the exam preparation experience and learning outcomes of high school students.

[0003] Existing test preparation supports on the market have many technical shortcomings that are difficult to overcome in practical applications: Firstly, the book fixing mechanism is mostly a single-sided or double-sided asynchronous clamping structure. It is difficult to achieve uniform centering and fixing for various learning materials of different sizes and thicknesses. Problems such as material skewing, edge warping, page rebound and slippage, and local clamping instability are likely to occur. In particular, the fixing reliability is extremely poor for commonly used materials such as large interview papers and thick teaching aids, and the stability and flatness of the materials cannot be guaranteed during reading and writing. Secondly, the fixing components are mostly exposed bosses or buckle structures. When not in use, they cannot be completely embedded and hidden in the bracket platform, which cannot guarantee the overall flatness of the bracket's bearing surface. This not only occupies extra storage space, but also easily causes book pages to scratch, stationery to slip off, and even poses a safety hazard of scratching the user. It cannot meet the requirements of clamping and fixing functions and the flatness of the platform when not in use. Third, the fixed operation requires manual adjustment on each side, which is cumbersome. Adjusting it during study breaks can easily disrupt the continuous learning rhythm. In addition, it lacks an adaptive stopping structure, and excessive clamping can easily cause spine damage, page tearing, and irreversible damage to the study materials. Fourth, the stand platform lacks three-dimensional flatness adjustment capability, making it unable to adapt to uneven usage scenarios on different desktops. At the same time, its functions are limited, making it difficult to integrate the various subject tools needed by high school students for exam preparation, and thus failing to meet the core needs of exam preparation in all scenarios. Summary of the Invention

[0004] The technical problem to be solved by this invention is that the existing test preparation supports are inconvenient for fixing books and have poor adaptability. To address this, we propose a three-dimensional adjustable integrated test preparation support for high school students' subject-specific tools.

[0005] To achieve the above objectives, this application adopts the following technical solution: a three-dimensional adjustable integrated exam preparation stand for high school students, comprising a platform with embedded windows around its perimeter, each embedded window containing a positioning strip, a three-dimensional support mounted on the back of the platform, and a control component for displacing the positioning strip on the back of the platform. The control component includes multiple mounting seats, each fixedly connected to the inner wall of one of the embedded windows, and a mounting cylinder fixedly connected to the top of each mounting seat. A first take-up roller is embedded within the mounting cylinder, and a first pull wire is wound and fixedly attached to the surface of the first take-up roller. The first pull wire is located away from the first take-up roller. One end of the winding roller is fixedly connected to the side of the positioning strip away from the center of the platform. A second winding roller is provided on the back of the center of the platform. Multiple second pull wires are wound and fixedly fixed on the surface of the second winding roller. The ends of the multiple second pull wires near the center of the platform are fixedly connected to the second winding roller. The ends of the multiple second pull wires away from the center of the platform are respectively fixedly connected to multiple positioning strips. A chassis is fixedly connected to the bottom of the second winding roller. Multiple evenly distributed teeth are fixedly connected around the bottom of the chassis. A rotating seat is provided at the bottom of the chassis. Multiple inclined slots are opened around the rotating seat. Limit seats are built into the inclined slots. A support spring is provided at the bottom of the limit seats.

[0006] Preferably, a baffle is fixedly connected to one side of the bottom of the platform.

[0007] Preferably, the positioning bar completely closes the embedded window.

[0008] Preferably, a receiving plate is fixedly connected to the inner wall of the embedded window, the top of the receiving plate contacts the positioning strip, and an inclined platform is provided on the end face of the receiving plate that contacts the positioning strip.

[0009] Preferably, the first take-up roller is rotatably connected to the bottom of the inner cavity of the mounting cylinder, and a coil spring is sleeved on one end of the bottom of the first take-up roller. One end of the coil spring is fixedly connected to the first take-up roller, and the other end of the coil spring is fixedly connected to the inner wall of the mounting cylinder.

[0010] Preferably, the platform surface has multiple grooves for inserting the second pull wire.

[0011] Preferably, one end of the second take-up roller is rotatably connected to the center of the back of the platform.

[0012] Preferably, one side of the tooth is an inclined surface, and the other side of the tooth is a vertical surface, with the limiting seat in contact with the inclined surface of the tooth.

[0013] Preferably, the rotating seat is rotatably connected to the bottom of the platform via a locking knob.

[0014] Preferably, one end of the support spring is fixedly connected to the limiting seat, and the other end of the support spring is sleeved and fixedly fitted with a positioning cylinder, the bottom of the positioning cylinder being fixedly connected to the bottom of the inclined groove cavity.

[0015] The technical effects and advantages of this invention are as follows: This invention addresses several problems of traditional exam preparation supports. Its platform features a two-section, rotatable rocker arm structure on its back, allowing for flexible adjustment of platform height, pitch angle, and horizontal orientation. The innovative design incorporates a hidden positioning bar clamping structure with multi-directional synchronous drive. Study materials can be secured and unlocked simply by rotating the rotating seat in both directions, eliminating the need for manual adjustment on each side. The rotating seat, through an adaptive clutch structure with teeth and limit seats, drives the second winding roller to synchronously wind up the cable, causing multiple positioning bars to converge towards the platform center. This provides stable, centered clamping for books and exam papers of different sizes and thicknesses, resolving common issues such as material skew, warped edges, and page slippage. Once the positioning bars are in contact with the materials, the clutch structure allows for adaptive adjustment of clamping force, preventing excessive clamping that could damage the spine or tear the pages. The positioning bar can be completely retracted into the platform's embedded window, remaining flush with the tabletop with no exposed protruding structures. This ensures the flatness of the tabletop and eliminates safety hazards such as page scratches and user injuries. The larger seating platform combines clamping functionality, safety, and ease of operation, meeting the high-frequency usage needs of high school students preparing for exams.

[0018] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0019] Reference Figures 1 to 8 As shown, the present invention provides a technical solution: a three-dimensional adjustable integrated study support for high school students, comprising a platform 1, a baffle 101 fixedly connected to one side of the bottom of the platform 1, embedded windows 102 opened around the platform 1, and positioning strips 103 built into the embedded windows 102, which completely close the embedded windows 102. A three-dimensional support 2 is installed on the back of the platform 1. The three-dimensional support 2 on the back of the platform 1 adopts a two-section rotatable rocker arm structure, which can freely rotate at multiple angles through the two rocker arms to realize the full-dimensional flexible adjustment of the height, pitch angle and horizontal orientation of the platform 1 in three-dimensional space. This allows the platform 1 to adapt to desktops of different heights, different reading and writing postures and eye heights of different users, and can also effectively compensate for the defects caused by uneven desktops. It ensures that the bearing surface of the platform 1 is always in an ideal state that adapts to the reading and writing needs of users, providing sufficient adjustment space for all scenarios of study preparation.

[0020] A control component 3 for displacing the positioning strip 103 is provided on the back of the platform 1. A receiving plate 104 is fixedly connected to the inner wall of the embedded window 102. The top of the receiving plate 104 contacts the positioning strip 103. An inclined platform 105 is provided on the end face of the receiving plate 104 that contacts the positioning strip 103. The control component 3 includes multiple mounting seats 301, which are fixedly connected to the inner walls of the multiple embedded windows 102 respectively. A mounting cylinder 302 is fixedly connected to the top of the mounting seat 301. A first winding roller 303 is built into the mounting cylinder 302. The first winding roller 303 is rotatably connected to the bottom of the inner cavity of the mounting cylinder 302. A coil spring 304 is sleeved on one end of the bottom of the first winding roller 303. One end of the coil spring 304 is fixedly connected to the first winding roller 303. The other end of the coil spring 304 is connected to the inner wall of the mounting cylinder 302. The first take-up roller 303 is fixedly wound with a first pull wire 305. The end of the first pull wire 305 away from the first take-up roller 303 is fixedly connected to the side of the positioning strip 103 away from the center of the platform 1. Relying on the rebound and reset characteristics of the coil spring 304, the first take-up roller 303 will continuously apply a stable take-up pulling force to the first pull wire 305. This pulling force will pull the positioning strip 103 to be smoothly stored in the embedded window 102 of the platform 1. At this time, the top surface of the positioning strip 103 is flush with the platform 1. The support plate 104 on the inner wall of the embedded window 102 forms a stable support for the positioning strip 103, so that the bearing surface of the entire platform 1 remains intact and flat, without any exposed protruding structure. From the structural root, it avoids various usage hazards caused by the fixed components in the idle state.

[0021] Additionally, a second take-up roller 306 is provided at the back center of platform 1. One end of the second take-up roller 306 is rotatably connected to the back center of platform 1. Multiple second pull wires 307 are wound and fixedly wound on the surface of the second take-up roller 306. The ends of the multiple second pull wires 307 near the center of platform 1 are fixedly connected to the second take-up roller 306, and the ends of the multiple second pull wires 307 away from the center of platform 1 are respectively fixedly connected to multiple positioning strips 103. The platform 1 has multiple grooves 106 for inserting the second pull wires 307. A base 308 is fixedly connected to the bottom of the second take-up roller 306. Multiple evenly spaced grooves are fixedly connected around the bottom of the base 308. The platform 1 has a base 308 with distributed teeth 309. A rotating seat 310 is located at the bottom of the base 308 and is rotatably connected to the bottom of the platform 1. Multiple inclined slots 311 are formed around the rotating seat 310, and a limiting seat 312 is built into each slot. One side of each tooth 309 is an inclined surface, and the other side is a vertical surface. The limiting seat 312 contacts the inclined surface of the tooth 309. A support spring 313 is located at the bottom of the limiting seat 312. One end of the support spring 313 is fixedly connected to the limiting seat 312, and the other end is fitted with a positioning cylinder 314. The bottom of the positioning cylinder 314 is fixedly connected to the bottom of the inner cavity of the inclined slot 311. When it is necessary to fix learning materials such as books and test papers, the user only needs to rotate the rotating seat 310 on the back of the platform 1 to complete the clamping operation. During the rotation of the rotating seat 310, the limiting seat 312 in its internal inclined groove 311 will form a stable meshing transmission with the teeth 309 at the bottom of the chassis 308. In the initial state, the support spring 313 will continuously push the limiting seat 312 upward, so that the inclined surface of the limiting seat 312 and the teeth 309 are closely fitted. The rotational force of the rotating seat 310 will be transmitted to the chassis 308 through the mating structure of the teeth 309 and the limiting seat 312, thereby driving the second take-up roller 306 to rotate synchronously. When the second take-up roller 306 rotates, it will synchronously take up multiple second pull wires 307. The traction force generated during the take-up process will synchronously drive the positioning strips 103 embedded in each window 102, so that the positioning strips 103 slide smoothly outwards towards the center of the platform 1 along the inclined platform 105 at the end of the receiving plate 104. Multiple positioning strips 103 move towards the center synchronously, which can form a multi-directional synchronous clamping and fixing effect on the learning materials placed on the platform 1. The inclined platform 105 of the receiving plate 104 is designed to provide a smooth guide for the sliding outwards of the positioning strips 103, avoiding the problem of jamming or sticking during the sliding process.

[0022] When the positioning bar 103 contacts the edge of the learning material and cannot move further towards the center, if the user continues to rotate the rotating seat 310, the continuous rotational force will cause the inclined surface of the teeth 309 to exert a downward squeezing force on the limiting seat 312. This squeezing force will overcome the elasticity of the support spring 313, pressing the limiting seat 312 downward into the inclined groove 311, causing the limiting seat 312 to disengage from the currently engaged teeth 309. The rotating seat 310 will then rotate freely for the stroke of one tooth 309 until the limiting seat 312 is pushed upward again by the rebound of the support spring 313, forming a new contact with the next tooth 309. This adaptive engagement and disengagement process will repeat as the rotating seat 310 continues to rotate, ensuring that the positioning bar 103 always maintains a stable clamping force against the edge of the learning material, achieving a reliable fixing effect, while avoiding damage and tearing to the spine and pages caused by excessive clamping. This achieves adaptive adjustment of clamping force and safe stopping. When it is necessary to release the fixation of the learning materials, simply rotate the rotating seat 310 in the opposite direction to quickly release the transmission limit between the tooth 309 and the limit seat 312. After the second take-up roller 306 loses the constraint of rotational force, the first take-up roller 303 will be pulled in the opposite direction by the spring 304 through the first pull line 305 to pull the positioning bar 103 in the opposite direction, so that the positioning bar 103 can slide smoothly back into the embedded window 102 along the inclined platform 105, and restore the flat state of the platform 1 surface. The entire unlocking process does not require additional side-by-side adjustment, making the operation more convenient and smooth.

[0023] The exam preparation stand, through its multi-directional synchronous driving positioning bar 103 structure, solves the inherent defects of traditional exam preparation stands that suffer from asynchronous clamping on one or both sides. Multiple positioning bars 103 are synchronously driven by the same winding transmission mechanism, enabling multi-directional synchronous convergence and clamping towards the center. It can achieve uniform centering and fixing of various learning materials commonly used by high school students, such as books, teaching aids, and large-format interview papers of different sizes and thicknesses. It effectively avoids common problems such as material skewing, edge warping, page rebound and slippage, and local instability. Even for thick teaching aids and large-format comprehensive test papers, the multi-directional synchronous clamping force can ensure that the materials remain stable and flat during reading and writing, greatly improving the applicability and reliability of the fixing structure and meeting the fixing needs of various learning materials during high school students' exam preparation.

[0024] The positioning strip 103 adopts a fully recessed hidden design. When not in use, it can be completely stored in the embedded window 102 of the platform 1 surface, keeping it completely flush with the platform 1 surface. There are no exposed protrusions, buckles, or other structures, which not only ensures the overall flatness of the support surface and does not take up extra storage space, but also fundamentally avoids the scratching of book pages by exposed structures, the obstruction and slippage of stationery, and eliminates the safety hazard of exposed structures scratching users. It truly achieves a balance between clamping and fixing functions and the flatness of the platform 1 when not in use, breaking the technical bottleneck of traditional supports that cannot achieve both.

[0025] The bracket's fixing and unlocking operations can be completed by rotating a single component in both directions, eliminating the need for manual adjustment of the fixing components side by side. This significantly simplifies the operation, allowing for quick adjustments even during study breaks without disrupting the user's continuous learning rhythm. It is well-suited to the high-frequency adjustment needs of high school students during intense exam preparation. Furthermore, the adaptive stop structure formed by the teeth 309 and the limit seat 312 automatically adjusts the clamping force after the positioning strip 103 is in contact with the study materials. This avoids the over-clamping problem that easily occurs with manual adjustments in traditional brackets, effectively preventing irreversible damage to the materials such as spine breakage and page tearing. It provides comprehensive protection for the study materials, balancing ease of operation and safety.

[0026] The stand utilizes a two-section, rotatable rocker arm in a three-dimensional structure, enabling the platform 1 to be flexibly adjusted in all three dimensions. This allows it to adapt to desktops of varying flatness, different usage scenarios, and varying reading and writing postures and eye levels, completely resolving the limitations of traditional stands that cannot accommodate uneven desktops. Furthermore, the platform 1 features a modular design with an embedded window 102 and a retractable positioning strip 103. The flat desktop provides ample space for integrated expansion, allowing for the integration of various subject-specific tools needed for high school students' exam preparation. This breaks away from the limitations of traditional stands with their single function, meeting the specific needs of high school students preparing for exams.

[0027] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
