Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a study desk that is convenient to use. Background Art

[0002] The desktop of a traditional study desk usually remains in a fixed horizontal state and is difficult to adapt to different learning needs. To solve this problem, the Chinese utility model patent CN216822229U proposes an innovative desktop angle adjustment solution. This solution symmetrically arranges hydraulic rods on both sides of the table frame and combines with a hinge structure to achieve a flexible conversion of the study board from a horizontal state to a ramp structure. Specifically, users can easily adjust the desktop to the desired tilt angle by controlling the telescoping of the hydraulic rods. Whether it is painting, reading or other learning activities, the most suitable working posture can be found. This design not only greatly enriches the functions of the study desk, meets diverse learning needs, but also effectively avoids neck and back discomfort that may be caused by working with the head down for a long time, thus improving the learning experience and the health level of users.

[0003] Although the adjustment mechanism combining hydraulic rods and hinges provided by CN216822229U performs excellently in terms of flexibility, there are also certain limitations and potential problems. First, the maintenance of the hydraulic system is relatively complex and requires regular inspections and maintenance to ensure its normal operation. Second, problems such as hydraulic oil leakage or component wear may occur during the long-term use of the hydraulic system, which not only affects the reliability of the adjustment function but may also lead to equipment failures. Finally, for some user groups, especially children and the elderly, it may take some time to learn and adapt to operating the hydraulic rods to adjust the desktop angle, increasing the difficulty of use. Therefore, in practical applications, these factors need to be comprehensively considered and the design continuously optimized to improve the user experience and market competitiveness of the product.

Detailed Embodiments

[0023] The following will further describe in detail the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] The structure of the study desk in this embodiment is asFigures 1 to 5 As shown, it includes fixed table legs 1, movable table legs 2 and a table frame 3. The fixed table legs 1 and the movable table legs 2 are installed in an up-and-down sleeved manner, where at least part of the movable table legs 2 can slide inside the fixed table legs 1, and the two together form a complete support leg unit. There are two groups of such support leg units, evenly distributed under the table frame 3 to ensure the stability of the tabletop. Specifically, the top of the movable table legs 2 of each group of support legs is firmly connected to the bottom of the table frame 3, while the bottom end is slidably installed inside the corresponding fixed table legs 1. A height adjustment mechanism is provided between the fixed table legs 1 and the movable table legs 2. With the help of the height adjustment mechanism, the movable table legs 2 can freely extend and retract within the fixed table legs 1, thus realizing flexible adjustment of the overall height of the study table. In addition, a movable table board 4 and an angle adjustment mechanism are installed on the table frame 3, enabling the movable table board 4 to not only be hinged at the front end of the table frame 3, but also change the tilt angle under the action of its angle adjustment mechanism, meeting the needs of users in different scenarios, such as painting, reading, etc., and helping users find the most suitable working posture for themselves.

[0025] The angle adjustment mechanism includes a first screw rod 5 rotatably arranged on the left and right sides of the table frame 3, a slider 6 threadedly engaged with each first screw rod 5, a support rod 7 connecting each slider 6 to the movable table board 4, a first linkage mechanism connected between the two first screw rods 5, and a control mechanism 8 for controlling the rotation of the first linkage mechanism. By driving the first linkage mechanism to rotate through the control mechanism 8, the first screw rod 5 is driven to rotate, causing the slider 6 to move along the first screw rod 5, and finally realizing the change of the tilt angle of the movable table board 4. The specific implementation method is that sliding grooves 9 are provided on both sides of the table frame 3, the first screw rod 5 is rotatably installed in the sliding grooves 9, and the slider 6 can slide in the sliding grooves 9 and is threadedly connected to the first screw rod 5. One end of the support rod 7 is rotatably connected to the slider 6, and the other end is rotatably connected to the movable table board 4. The first linkage mechanism consists of a first linkage rod 10 and first steering gears 11 at both ends thereof. The first steering gears 11 are responsible for transmitting the power of the first linkage rod 10 to the corresponding first screw rod 5 on each side. The first steering gears 11 can be conventional spiral bevel gear steering gears, and their functions are to realize power steering and support. It should be noted that after the first linkage rod 10 passes through the first steering gear 11 on one side, a first transmission rod 12 is connected through another first steering gear 11. The first transmission rod 12 penetrates through the front side of the table frame 3 and is connected to the control mechanism 8, that is, the crank. This means that by only rotating the crank, the first linkage mechanism can be started through the first transmission rod 12, prompting the first screw rod 5 to rotate, and then causing the slider 6 to slide along the first screw rod 5, resulting in the change of the tilt angle of the movable table board 4. Compared with the traditional method of combining hydraulic rods and hinges, the angle adjustment mechanism of this embodiment simplifies the maintenance process and avoids the complex maintenance requirements of the hydraulic system; improves the reliability of the system, the mechanical transmission method is more robust, and common faults such as oil leakage or wear are not likely to occur; at the same time, the operation is also more convenient, and the user can easily adjust the angle of the movable table board 4 only through the simple control mechanism 8, which is suitable for users of all ages.

[0026] For the height adjustment mechanism, it shares the same control mechanism 8 with the angle adjustment mechanism, specifically including a second screw rod 13 rotatably arranged in the fixed table leg 1 and a second linkage mechanism connected between the two second screw rods 13. The movable table leg 2 is sleeved outside the second screw rod 13 and is thread-matched with it. The second linkage mechanism consists of a second linkage rod 14 and second steering gears 15 at both ends thereof. Each second steering gear 15 is responsible for transmitting the power of the second linkage rod 14 to the corresponding second screw rod 13. The second steering gear 15 can be a conventional spiral bevel gear steering gear, and its function is to achieve power steering and support. Similarly, after the second linkage rod 14 passes through the second steering gear 15 on one side, it is connected to a second transmission rod 16 through another second steering gear 15. One end of the second transmission rod 16 penetrates the front end of the table frame 3 and is connected to the control mechanism 8. In this way, the user removes the crank from the first transmission rod 12 and then installs it on the second transmission rod 16, and can drive the second transmission rod 16 to rotate by rotating the crank, and then drive the two second screw rods 13 to rotate synchronously through the second linkage mechanism. As the second screw rod 13 rotates, the movable table leg 2 thread-mated with it will move up and down in the fixed table leg 1, so as to realize the adjustment of the height of the study table. After the height adjustment is completed, just reinstall the crank back to the first transmission rod 12 to restore the angle adjustment function.

[0027] To facilitate the user to quickly switch between height adjustment and angle adjustment, the second transmission rod 16 and the first transmission rod 12 are arranged in parallel and adjacent to each other, and the crank can be selectively connected to one of them according to needs. In addition, a sliding table board 17 and its supporting sliding columns 18 are also equipped on the table frame 3. A cross beam 19 is provided at the bottom of the sliding table board 17, and the cross beam 19 penetrates through the sliding columns 18, allowing the sliding table board 17 to slide along the sliding columns 18. This sliding table board 17 is arranged close to the movable table board 4, which can not only protect the internal components, but also serve as a platform for supporting the user's elbows, enhancing the comfort of use.

[0028] As described above, the study table in this embodiment fully considers the user's convenience of use, especially reflected in the simple operation of height and angle adjustment. Since the height adjustment mechanism and the angle adjustment mechanism share the same control mechanism 8, that is, the crank, the user can complete the two adjustments only through simple steps. Specifically, the user can easily realize the adjustment of the tilt angle of the movable table board 4 or the change of the overall height of the study table by rotating the same crank. When the angle of the movable table board 4 needs to be adjusted, connect the crank to the first transmission rod 12; if the height of the table needs to be adjusted, switch the crank to the second transmission rod 16. This design not only simplifies the operation process, avoids the use of additional control devices, but also enhances the overall coordination and user-friendliness of the system, enabling users of different ages to quickly get started and enjoy a personalized use experience.

[0029] The utility model is not limited to the above specific embodiments. Those of ordinary skill in the art can make various changes starting from the above conceptions without creative efforts, and all such changes fall within the protection scope of the utility model.
