Description

Technical Field

[0001] This utility model belongs to the technical field of learning tools, specifically relating to a highly stable anti-slip writing board. Background Technology

[0002] In daily learning, office work, rehabilitation care, or home leisure scenarios, writing tablets serve as a portable support platform, widely used for writing, reading, drawing, or placing electronic devices such as tablets. However, most existing writing tablets adopt a fixed height and single tilt angle design. While some have adjustment functions, they often rely on friction hinges, spring clips, or simple bolt structures, making it difficult to maintain stability after adjustment. They are prone to angle shifting or even sudden collapse due to hand pressure, device weight, or slight impacts. Their bottoms usually only have a flat base or a thin rubber pad, offering limited anti-slip capabilities on smooth desktops, hospital beds, or inclined surfaces, making them prone to displacement during use and affecting operational safety and user experience. Furthermore, most products have low functional integration, lacking practical features such as lighting mounting interfaces, cup storage, auxiliary trays, and ergonomic cushions, making it difficult to adapt to diverse usage environments and users' comprehensive needs for comfort and convenience.

[0003] In existing technologies, the height and tilt adjustment of writing tablets usually rely on simple hinges, friction damping, or elastic buckles. These structures are prone to loosening, slipping, or even sudden collapse during use due to external forces or their own weight, making it difficult to maintain a stable working angle. At the same time, their bottoms are mostly hard flat surfaces or simple rubber pads, lacking effective anti-slip designs between them and supporting surfaces such as desktops or beds. They are prone to slipping when used in an inclined posture or on smooth surfaces, which can easily cause safety hazards. In addition, most writing tablets have limited functions, only providing a basic writing platform and not integrating practical modules such as lighting mounting positions, cup placement areas, auxiliary trays, or ergonomic backrests, making it difficult to meet the diverse and comfortable needs of users in learning, office, or lying positions.

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This is an embodiment of the present invention, which provides a highly stable anti-slip writing board, comprising: The support mechanism 100 includes a writing board body 101, a support leg 102 disposed at the bottom of the writing board body 101, a lamp arm mounting base 103 disposed at the top of the writing board body 101, a cup holder 104 formed on the outer surface of the writing board body 101, a placement plate 105 hinged to the outer surface of the writing board body 101, a protective cushion 106 fixedly disposed on the outer surface of the writing board body 101, an adjustment knob 107 rotatably connected to the writing board body 101, an arc-shaped connecting tube 108 used in conjunction with the adjustment knob 107, and a limiting buckle 109 used in conjunction with the adjustment knob 107 and the arc-shaped connecting tube 108. The adjustment mechanism 200 includes a throttle 201 rotatably connected to the inner surface of the support leg 102, a first bevel gear 202 fixedly connected to the end of the throttle 201, a second bevel gear 203 meshing with the first bevel gear 202, and a lifting assembly 204 for adjusting the height of the support leg 102 when the throttle 201 is rotated.

[0019] The writing board body 101 serves as the main support platform for placing writing paper or electronic devices. Support legs 102 at its bottom provide overall support, ensuring stability during use. A lamp arm mounting base 103 at the top can be used to install lighting fixtures to meet different lighting needs. A cup holder 104 on the outer surface facilitates the placement of water cups or stationery, enhancing usability. A hinged placement board 105 can be flipped open for temporary placement of books or documents. A protective cushion 106 fixed to the upper edge provides cushioning and anti-slip protection when the user leans against it or writes. An adjustment knob 107 works in conjunction with an arc-shaped connecting tube 108 to adjust the angle of the writing board body 101 by rotation. A limiting buckle 109 works in conjunction with the adjustment knob 107 and the arc-shaped connecting tube 108 to lock at multiple preset angle positions, preventing the board from sliding or shaking due to gravity or external forces during use. This ensures that the entire support mechanism 100 maintains high stability and anti-slip performance in various usage postures.

[0020] Specifically, the lifting assembly 204 includes a fixing block 2041 fixedly installed on the inner wall of the support leg 102, a threaded rod 2042 fixedly connected to the second bevel gear 203, an internal threaded block 2043 threadedly connected to the threaded rod 2042, a lifting rod 2044 fixedly connected to the outer surface of the internal threaded block 2043, and an anti-slip pad 2045 fixedly installed at the end of the lifting rod 2044.

[0021] When the user rotates the handle 201, the handle 201 drives the first bevel gear 202 to rotate synchronously. The first bevel gear 202 meshes with the second bevel gear 203, thereby transmitting the horizontal rotational motion to the vertically set threaded rod 2042. The threaded rod 2042 and the internal threaded block 2043 form a threaded pair, so that the internal threaded block 2043 moves up and down along its axis when the threaded rod 2042 rotates. Since the internal threaded block 2043 is fixedly connected to the lifting rod 2044, the lifting rod 2044 moves linearly up and down inside the support leg 102. The anti-slip pad 2045 fixed at the end of the lifting rod 2044 extends and retracts synchronously with the lifting rod 2044, thereby changing the effective support height of the support leg 102. At the same time, the outer surface of the lifting rod 2044 slides against the inner wall of the support leg 102 to ensure that the lifting process is smooth and without swaying. Through this structure, the user can easily adjust the overall height of the writing board to adapt to different usage scenarios or ergonomic needs, while maintaining good anti-slip stability at the bottom.

[0022] Furthermore, the throttle 201 passes through the support leg 102 and is fixedly connected to the first bevel gear 202. A bearing is provided at the point where the throttle 201 passes through the support leg 102. The second bevel gear 203 is rotatably connected to the fixing block 2041, and a bearing is provided at the connection point.

[0023] Furthermore, the threaded rod 2042 passes through the fixing block 2041 and is fixedly connected to the second bevel gear 203, and the outer surface of the lifting rod 2044 slides in contact with the inner surface of the support leg 102.

[0024] Furthermore, the anti-slip mat 2045 is made of rubber material with anti-slip texture on its bottom surface.

[0025] Preferably, the outer surface of the protective cushion 106 is covered with a removable and washable fabric cover, and the arc-shaped connecting tube 108 is a hollow metal tube, with its two ends connected to the writing board body 101 and the adjustment knob 107 respectively via pins.

[0026] It should be noted that the limit buckle 109 consists of multiple positioning grooves arranged around the arc-shaped connecting pipe 108. The adjusting knob 107 cooperates with the positioning grooves to achieve multi-angle locking.

[0027] In use, the user first places the high-stability, non-slip writing board on a support surface such as a desktop, bed, or floor. At this time, the non-slip pads 2045 on the bottom of the support legs 102 are in close contact with the contact surface. The rubber material and non-slip texture on the bottom effectively increase friction and prevent the writing board from sliding. If the height needs to be adjusted to suit sitting, lying, or different height requirements, the user can rotate the handle 201. The handle 201, through the meshing of the first bevel gear 202 and the second bevel gear 203, converts the horizontal rotational motion into a vertical threaded transmission, driving the threaded rod 20 42 rotates, thereby driving the internal threaded block 2043, which is threaded to it, to move axially. Since the internal threaded block 2043 is fixedly connected to the lifting rod 2044, the lifting rod 2044 slides smoothly up and down inside the support leg 102, thereby changing the extension length of the anti-slip pad 2045 and realizing stepless or segmented adjustment of the overall height of the support leg 102. After adjustment, the writing tablet body 101 is held at the required height, stably supporting writing or reading operations. Users can place paper, books or tablet computers on the writing tablet body 101. The protective cushion 1 at the upper edge 06 provides cushioning support for the arm or chest, and its removable fabric cover facilitates cleaning and maintenance. When the tilt angle of the writing board needs to be adjusted for a more comfortable viewing angle, the user releases the adjustment knob 107, causing the arc-shaped connecting tube 108 to rotate relative to the writing board body 101. After the board reaches the appropriate angle, the adjustment knob 107 is tightened again, causing it to engage with the circumferentially set limit buckle 109 of the arc-shaped connecting tube 108, i.e., multiple positioning grooves interlock to achieve multi-level angle locking, effectively preventing the board from slipping due to gravity or hand pressure during use. At the same time, the top... The lamp arm mounting base 103 can hold LED desk lamps and other lighting equipment, providing directional supplementary lighting for nighttime or low-light environments. The cup holder 104 on the side is used to place small items such as water cups and pen holders, avoiding taking up writing space. The hinged mounting plate 105 can be flipped down or sideways to temporarily support reference books, mobile phones or stationery, improving versatility and operational efficiency. With the synergistic effect of height adjustment, angle locking, bottom anti-slip, and integrated functions, the entire structure ensures that users can obtain a stable, comfortable and convenient writing and reading experience in various usage scenarios.

[0028] In summary, by setting up a lifting assembly 204 driven by bevel gear transmission and a multi-position limit angle adjustment mechanism 200, the support height can be smoothly adjusted and the writing tilt angle can be reliably locked, effectively preventing slippage or shaking caused by gravity or external force during use. At the same time, the bottom uses rubber feet 2045 with anti-slip texture to improve the grip performance on different support surfaces. It also integrates functional modules such as lamp arm mounting base 103, cup holder 104, placement board 105 and protective cushion 106. While ensuring high stability and anti-slip performance, it also takes into account the needs of lighting, storage and ergonomic support, comprehensively improving the practicality, safety and comfort of the writing board.
