Description

Technical Field

[0001] The invention relates to the technical field of reading tables, in particular to a size-adjustable reading table. Background Art

[0002] An existing reading desk is a piece of furniture used for reading, studying, and working. It is usually made of sturdy materials such as wood, metal, or plastic, and has a flat desktop for placing books, laptops, documents, and other items needed for study or work. The design of a reading desk usually takes ergonomics and comfort into consideration. However, the angles of existing desktops vary, and it is difficult to adjust them to the optimal reading position when the reader is reading. Traditionally, a flip angle of the desktop between 15 degrees and 30 degrees is considered to be the most suitable for reading. This angle can keep the reading material closer to the eyes, providing a clearer line of sight and a clearer focus.

[0003] However, when adjusting the angle of existing desktops, the angle adjustment design of these desktops requires multiple adjustment points, such as side buttons, lower adjustment columns, etc., which need to be adjusted separately. Such a design increases the adjustment steps and operation complexity, and requires manual adjustment. Not only does it require users to spend more time and energy to adjust the angle of the desktop, but it may also cause fatigue and discomfort to users who need to read, write or work for a long time, which may cause users to be unable to concentrate on reading, writing or working, thereby affecting the quality and progress of work. Moreover, the complicated adjustment process may cause users to feel less comfortable when using the reading table for a long time, which may cause physical discomfort such as muscle tension and cervical pain, thereby affecting the health of the user.

[0004] In addition, traditional reading books cannot be folded, while non-foldable tables have a mechanism that allows the table to be easily folded when not in use, reducing the space it occupies. Non-foldable tables always maintain a fixed shape and occupy a relatively large space. For users with small apartments or limited space, this type of desk may cause a waste of space and make the room appear more crowded. If there is no suitable storage space, the desk may occupy part of the room, resulting in messy placement or inability to fully utilize the space.

[0005] Therefore, a size-adjustable reading table is proposed to solve the above problems. Summary of the Invention

It can also be personalized according to the height and usage needs of different users. Everyone has different heights and habits. By automatically adjusting the height, everyone can find the working posture that suits them best and reduce physical discomfort and fatigue.

[0048] For further examples, please refer to Figures 1 to 7 As shown:

[0049] The angle adjustment mechanism 4 includes a sliding tooth groove 401, which is evenly arranged on the side of the working surface 104. A gear 402 is meshed with the sliding tooth groove 401. A rotating hole is opened on the fixed column 403. A rotating shaft 404 is fixedly connected to the middle of the gear 402. The middle of the rotating shaft 404 is rotatably connected to the rotating hole of the fixed column 403.

[0050] The rotating shaft 404 is rotatably connected to a rotating wheel 405 at one end away from the gear 402. The middle portion of the rotating wheel 405 is rotatably connected to the fixed column 403. An extrusion bar 406 is fixedly connected to the outer surface of the rotating wheel 405. A multifunctional rotating disk 407 is provided on the right side of the extrusion bar 406. The multifunctional rotating disk 407 is evenly provided with arc grooves 408.

[0051] The extrusion bar 406 slides in the arc-shaped groove 408. A sliding groove is provided in the middle of the fixed column 403. A connecting shaft 409 is fixedly connected to the middle of the multi-function turntable 407. One end of the connecting shaft 409 is rotatably connected to the sliding groove provided in the fixed column 403. The other end of the connecting shaft 409 passes through the sliding groove of the fixed column 403 and is fixedly connected to the reading table 103.

[0052] The angle adjustment mechanism 4 is symmetrically arranged on the fixed columns 403 on both sides of the reading desktop 103. When the working surface 104 is unfolded along the bottom of the reading desktop 103, the reading desktop 103 can be adjusted and flipped counterclockwise.

[0053] In the prior art, traditional reading desks are usually large in size and take up space in the room. For users with small apartments or limited space, such desks may cause a waste of space and make the room appear more crowded. If there is no suitable storage space, the desk may occupy part of the room, resulting in a messy placement or inability to fully utilize the space. Compared with the prior art, through the implementation of this embodiment, the desk can be folded and unfolded while also adjusting the angle of the desktop, so that users can adjust the desktop angle according to their needs and working methods, thereby obtaining a more comfortable and efficient working environment. At the same time, when the folding desk is unfolded, flipping the desktop at an appropriate angle can keep the eyes and head in a natural posture, reducing the burden on the neck. Compared with a flat desktop, the appropriate angle helps to reduce neck fatigue and discomfort caused by reading with the head down for a long time.

[0054] Everything in the above example works as follows:

[0055] In the initial state, the working surface 104 and the reading table 103 are unfolded with each other, and the spring rod 205 is stretched. When the working surface 104 is unfolded along the bottom of the reading table 103, the reading table 103 can be adjusted and flipped counterclockwise.

[0056] The following is the working process of the adjustable folding mechanism 2 adjusting the size of the desktop and the stability adjustment mechanism 3 adjusting the stability of the desktop:

[0057] When in use, the reading desk is initially in the unfolded state according to the needs of the reader. When the reader finishes reading, he can manually push the work surface 104. Because a sensor is provided on the table baffle 101, when the position sensor on the table baffle 101 detects that the work surface 104 slides to the right side of the table baffle 101, the sensor controls the motor 301 to rotate clockwise. At this time, the clockwise rotation of the motor 301 drive shaft drives the worm 303 to start rotating clockwise. Because the worm 303 is engaged with the turbine 305, the worm 303 is engaged with the turbine 305. 3. The clockwise rotation will drive the turbine 305 to start rotating counterclockwise on the small bracket 304. At this time, because the tooth surface of the turbine 305 away from the worm 303 is meshed with the vortex groove 306, the counterclockwise rotation of the turbine 305 will drive the sliding column 207 to start sliding upward in the L-shaped leg 206. At this time, the sliding column 207 begins to shrink in the L-shaped leg 206. By setting the stable adjustment mechanism 3, the adjustment can be started by one button, which is simple and convenient to operate, and the ideal working height can be quickly obtained, saving time and energy for manual adjustment.

[0058] As the work surface 104 is pushed to the right along the table baffle 101, the crank 203 begins to rotate counterclockwise on the U-shaped bracket 201 because it is squeezed by the bottom of the table baffle 101. At this time, the swing arm 204 rotatably connected to the other end of the crank 203 begins to rotate counterclockwise around the crank 203. At this time, the counterclockwise rotation of the crank 203 will cause the crank 203 to generate a push to the upper right. At this time, the spring rod 205 in the middle of the swing arm 204 begins to shrink, and the L-shaped leg 206 of the swing arm 204 away from the end of the crank 203 begins to rotate clockwise on the U-shaped bracket 201 under the push of the swing arm 204 to the right. At this time, due to the shrinkage of the sliding column 207 in the L-shaped leg 206 and the push of the work surface 104, The L-shaped leg 206 will rotate clockwise to the left side and be located below the work surface 104, so that the crank 203 will rotate from the bottom to the top of the bottom of the table baffle 101, and the work surface 104 will be pushed down to the side of the table baffle 101 again to fold the adjustable folding mechanism 2 as a whole in the table baffle 101. The adjustable folding mechanism 2 is set to increase the folding function and can be used according to personal use. At the same time, each person's height and habits are different. By automatically adjusting the height, everyone can find the working posture that suits them best, reduce physical discomfort and fatigue, and the automatic adjustment of the height between the table and the ground can be started by one button. The operation is simple and convenient, so that the user only needs to press a button to adjust, and can quickly obtain the ideal working height, saving time and energy for manual adjustment.

[0059] Please refer to the above working process Figures 1 to 7 .

[0060] The following is a working process of the angle adjustment mechanism 4 automatically adjusting the angle of the reading table 103:

[0061] When in use, when the reader pushes the working surface 104 into the table baffle 101, the sliding tooth grooves 401 evenly opened on both sides of the working surface 104 are meshed with the gears 402, and the sliding tooth grooves 401 start to move as the working surface 104 pushes into the interior of the table baffle 101. Figure 6 As shown, it moves to the right, at this time, the sliding tooth groove 401 will drive the meshing gear 402 to start rotating clockwise in the rotating hole of the fixed column 403. At this time, the clockwise rotation of the gear 402 will drive the shaft 404 to drive the wheel 405 to start rotating clockwise, because the extrusion bar 406 fixedly connected to the wheel 405 slides in the arc groove 408 opened on the multi-function turntable 407. As the spring rod 205 rotates clockwise, the extrusion bar 406 can slide at the arc connection and drive the multi-function turntable 407 to start rotating and adjusting in the clockwise direction. At this time, because the middle part of the multi-function turntable 407 is fixed to the connecting shaft 409, and the other end of the connecting shaft 409 is fixed to the reading desktop 103, the clockwise rotation of the multi-function turntable 407 will cause the reading desktop 103 to also start adjusting in the clockwise direction. When the working surface 104 is completely pushed into the table baffle 101, at this time Under the action of the position sensor, the motor 301 is powered off, and at the same time, the sliding groove 401 drives the gear 402 to rotate clockwise, so that the extrusion bar 406 squeezes the arc groove 408 and drives the multi-function turntable 407 to rotate clockwise, so that the reading desktop 103 is just rotated to the pad set on the table baffle 101, so that the reading desktop 103 is rotated horizontally and stably to the pad of the table baffle 101. Through the setting of the angle adjustment mechanism 4, the desktop angle can be adjusted while folding and unfolding the desk, so that the user can adjust the desktop angle according to his needs and working methods, so as to obtain a more comfortable and efficient working environment. At the same time, when the folding desk is unfolded, flipping the desktop at an appropriate angle can keep the eyes and head in a natural posture, reducing the burden on the neck. Compared with a flat desktop, a suitable angle helps to reduce neck fatigue and discomfort caused by reading with the head down for a long time.

[0062] Please refer to the above working process Figures 1 to 7 .
