Description

Technical Field

[0001] This utility model relates to the field of multifunctional table technology, and in particular to a leveling structure and a multifunctional table using the leveling structure. Background Technology

[0002] With the increasing demand for space utilization and functional versatility in offices, homes, and educational settings, multi-functional tables, as furniture capable of folding, height adjustment, and rotation, have been widely used in home studies, open-plan offices, and training classrooms. Among these features, the leveling function of the desktop is one of the core elements ensuring a good user experience. An uneven desktop can not only cause items to be placed unstably and electronic devices to tilt and be damaged, but it can also cause wobbling during writing and operation, affecting user comfort and work efficiency. Especially for rotatable or foldable multi-functional tables, the desktop is prone to tilting during unfolding or folding due to structural gaps or assembly errors. Therefore, a reliable leveling structure is needed to ensure the desktop's horizontal stability under different usage conditions.

[0003] However, existing desktop leveling structures still have significant drawbacks. Traditional leveling operations are cumbersome, requiring tools and time-consuming, making it difficult to meet users' needs for quickly switching desktop states. Some structures use elastic components or friction plates for limiting, resulting in insufficient stability. After long-term use, material fatigue can lead to a decrease in leveling accuracy, or even desktop misalignment. The connection structure between the leveling components and the desktop is complex and has poor adaptability, usually requiring customization for specific desktop types, making it difficult to be compatible with desktop designs of different sizes or rotation angles. When the desktop is rotated and unfolded around the support axis, existing leveling structures often cannot achieve precise engagement between the positioning block and the sliding groove through simple operations, resulting in limited leveling range or unreliable locking.

[0004] Therefore, a desktop leveling structure that is simple in structure, easy to operate, and can improve the flatness between different desktops is needed to make the multi-functional table more applicable and perform better. Utility Model Content

[0020] 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.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] This utility model provides a method such as Figures 1 to 4 The leveling structure shown includes: Guide seat 1 is fixedly installed on a tabletop. A guide groove 101 is opened on one side of the guide seat 1, and a positioning block 102 is set at the edge of the guide groove 101. The leveling component 2 includes a fixed base 201 fixedly installed on another tabletop, and a leveling block 202 rotatably installed on the fixed base 201; a fixed hole 2011 is opened in the center of the fixed base 201; a sliding groove 2021 is provided on one side of the leveling block 202, a stop bar 2022 is provided at one end of the sliding groove 2021 along the sliding path, and the other end is open; The positioning block 102 slides synchronously along the sliding groove 2021 as the leveling block 202 rotates, and the positioning block 102 abuts against the stop bar 2022 or completely disengages from the sliding groove 2021 during the sliding process.

[0024] The working principle of this utility model is as follows: The guide seat 1 and leveling component 2 in the leveling structure 7 are respectively installed on two adjacent tabletops. When there is relative wobbling or unevenness between the two tabletops, rotating the leveling block 202 causes the sliding groove 2021 to move towards the positioning block 102, so that the positioning block 102 slides into the sliding groove 2021 from the open end of the sliding groove 2021 until the positioning block 102 abuts against the stop strip 2022 at one end of the sliding groove 2021 and stops rotating the leveling block 202. At this time, the leveling component 2 and the guide seat 1 are connected by the positioning block. The contact between positioning block 102 and sliding groove 2021 creates a constraint, thereby reducing the relative wobbling between two adjacent tabletops and improving the flatness of the two tabletops. This effectively solves the problems of cumbersome and unstable traditional leveling operations and improves leveling efficiency. When the two tabletops do not need to be level, the leveling block 202 is rotated in the opposite direction, causing the sliding groove 2021 to gradually move away from the positioning block 102, eliminating the constraint caused by the contact between the positioning block 102 and the sliding groove 2021. This allows the two tabletops to be adjusted differently to meet the user's requirements.

[0025] Based on the above embodiments, the edge of the sliding groove 2021 near the positioning block 102 can be set in an inclined shape along the length direction, that is, the edge width at the opening is smaller than the edge width at the stop bar 2022. This prevents the user from changing the angle of a tabletop before the sliding groove 2021 is fully rotated away from the positioning block 102, which would cause damage to the leveling structure 7. This effectively improves the fault tolerance of the leveling structure 7 and extends its service life.

[0026] In some embodiments of this utility model, such as Figure 4 As shown, a handle 2023 is provided on one side of the leveling block 202, providing a clear gripping point for the user. The rotation of the leveling block 202 can be controlled directly by gripping the handle 2023 with the hand, which effectively improves the convenience and smoothness of operation.

[0027] In some embodiments of this utility model, such as Figure 4 As shown, a guide bar 2012 is provided circumferentially on the fixed base 201; a rotating groove 2024 is opened on one end face of the leveling block 202, and the guide bar 2012 extends into the rotating groove 2024. The leveling block 202 rotates on the fixed base 201 through the rotating groove 2024. The circumferential cooperation between the guide bar 2012 and the rotating groove 2024 can effectively limit the radial displacement of the leveling block 202 and avoid eccentric wobbling during rotation. At the same time, the axial embedding design can prevent the leveling block 202 from separating from the fixed base 201, effectively solving the problem of insufficient stability during rotation, making the leveling block 202 rotate more smoothly and the positioning more accurate, thereby improving the reliability of the leveling operation and the structural durability, providing a solid mechanical foundation for the efficient realization of desktop leveling, and can be achieved without complex processing.

[0028] In some embodiments of this utility model, such as Figure 2 As shown, the guide groove 101 is arc-shaped, and the positioning block 102 is arc-shaped on one side facing the center of the guide seat 1.

[0029] Based on the above embodiments, such as Figure 3 As shown, the sliding groove 2021 is arranged in an arc shape corresponding to the positioning block 102.

[0030] The arc-shaped guide groove 101 forms a surface contact with the arc-shaped side of the positioning block 102, which can disperse the contact stress during the sliding process and reduce local wear. The arc-shaped path of the sliding groove 2021 is adapted to the rotation trajectory of the leveling block 202, ensuring that the positioning block 102 slides smoothly along the preset arc, avoiding jamming or adjustment obstruction caused by trajectory deviation. This solves the problems of poor sliding and insufficient precision. Furthermore, the continuous contact of the arc-shaped surface improves the smoothness and labor-saving of the leveling operation, making the process from the positioning block 102 abutting the stop bar 2022 to its complete disengagement more stable and controllable. This enhances the durability and reliability of the leveling structure 7 in repeated adjustments, providing a structural foundation for the efficient realization of desktop leveling.

[0031] This utility model also provides a multifunctional table, using the leveling structure 7 described above. Please refer to [reference needed]. Figures 1 to 8 ,include: Base 3; Support rod 4 is fixedly installed on base 3, and a support tube 401 is fixedly installed on the top of support rod 4; The fixed desktop 5 is fixedly installed on one side of the support tube 401; The rotating tabletop 6 is installed on the other side of the support tube 401, close to the fixed tabletop 5. The rotating tabletop 6 can rotate around the support tube 401. A baffle can also be installed on one side of the rotating tabletop 6 to prevent items on the tabletop from slipping off after the rotating tabletop 6 is rotated to a certain angle. The leveling structure 7 includes a guide seat 1 fixedly installed at the bottom of the fixed tabletop 5, and a leveling component 2 fixedly installed at the bottom of the rotating tabletop 6 corresponding to the guide seat 1.

[0032] In this embodiment, the fixed desktop 5 remains horizontal and stationary, while the rotating desktop 6 can be rotated to change its angle. When it is necessary to rotate the desktop 6 to a certain angle to facilitate the user's use, the leveling structure 7 can be released to make adjustments. For example, it is more convenient to write on the desktop 6 after tilting it at an angle, reducing the user's head-down angle, thus protecting the user's health and reducing fatigue. When a larger area of ​​flat desktop is needed, the leveling component 2 can be rotated to create a restriction between it and the guide seat 1, thus maintaining relative stability between the fixed desktop 5 and the rotating desktop 6. This expands the usable desktop area while maintaining the flexibility of the rotating desktop 6 and the flatness of the two desktops.

[0033] In some embodiments of this utility model, such as Figure 8 As shown, the support rod 4 also includes an internally sliding lifting rod 402. The top of the lifting rod 402 is fixedly connected to the support tube 401. The lifting rod 402 drives the support tube 401 to make linear reciprocating motion along the length of the support rod 4. The linear reciprocating motion of the lifting rod along the length of the support rod 4 can directly drive the support tube 401 and the connected fixed desktop 5 and rotating desktop 6 to rise and fall synchronously without the need for additional disassembly or assembly of parts. Users can flexibly adjust the desktop height according to their needs, such as sitting office, standing study, or use by children. At the same time, the internal sliding structure avoids the space occupation problem of external adjustment parts, making the overall design simpler and more compact. In addition, the nested cooperation between the support rod 4 and the lifting rod 402 provides axial support force. Combined with the leveling structure 7 to ensure the horizontality of the desktop, it ensures that the desktop can still maintain a stable load-bearing and horizontal state after the height is adjusted. This effectively solves the problems of complex adjustment and poor stability of traditional height-adjustable desks, further expands the applicable scenarios and user groups of multi-functional desks, improves the ergonomic design and user comfort of the product, and provides users with a multi-functional desktop solution that combines high flexibility and structural reliability.

[0034] Based on the above embodiments, such as Figure 7 and Figure 8As shown, a lifting wrench 403 is installed on the side of the support tube 401 near the fixed desktop 5. The lifting wrench 403 is connected to the lifting rod 402 and is used to control the movement of the lifting rod 402. The specific installation position of the lifting wrench 403 can be selected to fit the user's operating habits. Whether sitting or standing, the user can operate it easily without changing their posture. The direct linkage between the wrench and the lifting rod 402 simplifies the control logic. The lifting rod 402 can be driven to slide along the support rod 4 by the wrench action, avoiding cumbersome steps, solving the problems of inconvenient operation and low efficiency, improving the convenience and accuracy of adjustment, and enabling the user to flexibly adjust the desktop height according to real-time needs.

[0035] In some embodiments of this utility model, such as Figure 8 As shown, a rotating sleeve 601 is provided between the rotating tabletop 6 and the support tube 401. The rotating sleeve 601 is fixedly connected to the rotating tabletop 6 and rotatably connected to the support tube 401. A limiting component 404 is provided on the support tube 401. The limiting component 404 reciprocates linearly along the length of the support tube 401. The limiting component 404 is used to limit the rotation of the rotating sleeve 601. The rotation of the rotating sleeve 601 around the support tube 401 drives the angle adjustment of the rotating table 6. When the limiting component 404 contacts the rotating sleeve 601 on the support tube 401, it achieves the effect of limiting the rotation of the rotating sleeve 601, so that the rotating table 6 cannot rotate and remains flush with the fixed table 5. When the rotating sleeve 601 needs to rotate, the limiting component 404 can be moved away from the rotating sleeve 601 to achieve quick locking and releasing of the rotating sleeve 601. Preferably, the side of the limiting component 404 near the rotating sleeve 601 can be designed as a circular toothed groove around the axis of the support tube 401. The circular toothed groove is sleeved on the support tube 401, and a sliding rod penetrating the support tube 401 is added inside the circular toothed groove to achieve the effect of driving the limiting component 404 to make linear reciprocating motion on the support tube 401. The rotating sleeve 601 is provided with several teeth corresponding to the meshing toothed groove, so that the effect of limiting the rotation of the rotating sleeve 601 to drive the rotating table 6 to rotate is better, and the possibility of the rotating table 6 still rotating slightly after locking is avoided.

[0036] Based on the above embodiments, such as Figure 8 As shown, a rotating seat 602 is fixedly installed on one side of the rotating tabletop 6. The rotating seat 602 is rotatably connected to the support tube 401. A rotating wrench 603 is installed at the bottom of the rotating seat 602. A tube-pulling assembly 405 is installed inside the support tube 401. One end of the tube-pulling assembly 405 is connected to a rotating wrench 603, and the other end is connected to a limiting assembly 404. The rotary wrench 603 is used to limit the rotation of the rotating sleeve 601 by driving the limit component 404 through the tube pulling assembly 405.

[0037] When a user wants to adjust the angle of the rotating desktop 6, they can apply force directly through the wrench at the bottom of the rotating base 602. The force is transmitted through the pull tube assembly 405, which is composed of a linkage, to the limiting assembly 404 inside the support tube 401, driving it to move along the length of the support tube 401 to lock or release the rotating sleeve 601. This design integrates the limiting control into the grip area of ​​the rotating desktop 6, allowing the user to complete the continuous action of rotating to the limit with one hand without changing the operating position. At the same time, the pull tube assembly 405 is built into the support tube 401, avoiding the space occupation and bump risk of external control rods, maintaining the simplicity of the table structure, ensuring the immediacy and accuracy of the control response, preventing the limit failure caused by transmission delay, and further improving the reliability of fixing the angle of the rotating desktop 6. This makes the multi-functional table have a more efficient human-computer interaction experience in dynamic usage scenarios, such as temporary tilted drawing and multi-angle display, and enhances the smoothness of product operation.
