To accommodate different user needs, reading desks on the market are usually designed with desktop angle adjustment mechanisms to change the relative angle between the tabletop and the legs. However, the structural design of these desktop angle adjustment mechanisms is complex, with numerous parts, making modular installation difficult. Furthermore, the main components of the desktop angle adjustment mechanism need to not only rotate but also move relative to each other, which can easily lead to structural instability, such as loosening, wear, or even reduced precision.

[0055] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies both A and B.

[0059] This invention discloses a desktop angle adjustment device. The angle adjustment device is a functional component designed to allow users to adjust the tilt of their desktop according to their individual needs for a more comfortable reading or working experience. This device typically consists of a mechanical structure, such as gears, supports, or hinges, which provides stable support for the desktop and allows for adjustment within a certain range. The adjustment function helps protect the user's eyesight and cervical spine health while improving efficiency. For example, adjusting to a suitable angle during prolonged reading or writing can reduce unnecessary fatigue and stress. Such devices are widely used in educational, office, and home environments.

[0060] In this embodiment of the utility model, please refer to Figures 1 to 16The desktop angle adjustment device 100 is used to connect the tabletop 70 and the table legs 80. The desktop angle adjustment device 100 includes a fixed module 10 and a rotating module 20: the fixed module 10 is used to install on the table leg 80; the fixed module 10 includes a first limiting part 11; the rotating module 20 is rotatably connected to the fixed module 10 about a preset horizontal axis 30, and the rotating module 20 includes a mounting base 21, an adjusting member 22, and a connecting member 23; the mounting base 21 is used to fixally connect to the tabletop 70, and the mounting base 21 has a mounting cavity 211; the connecting member 23 is movably placed in the mounting cavity 211 along the direction of the preset horizontal axis 30; the connecting member 23 includes a second limiting part 231 passing through the mounting base 21; part of the adjusting member 22 is exposed in the mounting cavity 211 for operation; part of the adjusting member 22 is rotatably placed in the mounting cavity 211 about the preset horizontal axis 30 to drive the connecting member 23 to reciprocate along the direction of the preset horizontal axis 30, and the adjusting member 22 has an unlocked position and a locked position;

[0061] When the adjusting member 22 is in the locked position, the first limiting part 11 and the second limiting part 231 are in a limiting engagement in the direction around the preset horizontal axis 30;

[0062] When the adjusting member 22 is switched to the unlocked position, the adjusting member 22 drives the adapter 23 to move so that the second limiting part 231 disengages from the first limiting part 11.

[0063] In this embodiment, the fixing module 10 is installed on the table leg 80 to provide a stable support point for the movement of the rotating module 20. The fixing module 10 includes a first limiting part 11. The first limiting part 11 cooperates with the second limiting part 231 to realize the limiting control of the tabletop 70. The two can be a snap-fit ​​or groove structure that cooperates with each other, which is not limited here.

[0064] The rotating module 20 is connected to the fixed module 10 via a preset horizontal axis 30, forming the core of rotatable control. This connection ensures that the tabletop 70 can flexibly adjust its angle. The rotating module 20 includes a mounting base 21, an adjusting component 22, and an adapter 23.

[0065] The mounting base 21 is mainly used to connect the tabletop 70 to ensure a secure connection between the tabletop 70 and the entire desktop angle adjustment device 100. The mounting base 21 is connected to the tabletop 70 by screws or other fixing methods, ensuring stable force distribution on the tabletop 70 during angle adjustment, thus preventing loosening or displacement. The specific connection method of the mounting base 21 is not limited here. The mounting base 21 has a mounting cavity 211, which accommodates other components in the rotating module 20 (such as the adjusting component 22 and the adapter 23), providing space for their installation and movement. The mounting base 21 provides the necessary mechanical support for the dynamic adjustment of the device, and the reasonable layout of the mounting cavity 211 allows the internal components to work together to complete the angle adjustment function.

[0066] When the adjusting member 22 switches between the unlocked and locked positions, the position of the mounting base 21 relative to the tabletop remains unchanged, while the position of the fixing module 10 relative to the table leg remains unchanged. In other words, during the position switching process, the relative positions of the fixing module 10 and the mounting base 21 in the direction of the preset horizontal axis 30 remain unchanged. Only the adjusting member 22 and the adapter 23 located within the mounting cavity 211 move to achieve the limiting and separation of the first limiting part 11 and the second limiting part 231.

[0067] The adjusting component 22 is the core component for user operation. Users can adjust the angle of the tabletop 70 from the unlocked position of the adjusting component 22; alternatively, the user can use the tabletop 70 stably at a fixed angle from the unlocked position of the adjusting component 22. Part of the adjusting mechanism is exposed in the mounting cavity 211, allowing users to easily rotate or move the adjusting component 22 to quickly set the angle of the tabletop 70.

[0068] The adapter 23 is placed inside the mounting cavity 211 and connected to the adjusting member 22. Through the rotation of the adjusting member 22 or other operations, the adapter 23 reciprocates within the mounting cavity 211 along a preset horizontal axis 30. This connection allows the adjusting member 22 to indirectly control the locking and unlocking states of the tabletop 70.

[0069] The adapter 23 includes a second limiting portion 231 that passes through the mounting base 21. The movement of the rotating member is directly related to the movement of the second limiting portion 231, avoiding movement delays that might occur if the second limiting portion 231 were located in an intermediate component or other component. This also means a reduction in the number of components.

[0070] The adapter 23 can move along a preset horizontal axis 30, and its movement determines the positional relationship between the second limiting part 231 and the first limiting part 11. In use, the user rotates the exposed adjusting part 22 to the unlocked state. The adapter 23 moves under the action of the adjusting part 22, causing the second limiting part 231 to disengage from the first limiting part 11. At this time, the user can adjust the angle of the tabletop 70 as needed. After adjustment, the user rotates the adjusting part 22 to the locked position, and the adapter 23 moves back to its original position, causing the second limiting part 231 to engage with the first limiting part 11, and the angle of the tabletop 70 is securely locked.

[0071] In related technologies, the components are complex and require individual assembly during user installation, leading to a cumbersome and error-prone assembly process. In this embodiment, the angle adjustment device's components are functionally divided into a fixed module 10 and a rotating module 20. Many components in the rotating module 20, such as the mounting base 21, adjusting parts 22, and conversion parts, can be pre-assembled, eliminating the need for on-site adjustments of internal precision parts by the user. The user simply connects the rotating module 20 to the fixed module 10 using simple snap-fit ​​or hook-and-loop kits. This not only ensures the accuracy and stability of the core functional units within the rotating module 20, improving product consistency, but also allows the user to focus solely on pre-assembled functional modules during assembly, reducing tedious component assembly steps and lowering the initial assembly error rate. Furthermore, this modular design facilitates transportation.

[0072] Related technologies use rotating module 20 to move the fixed module 10 away from the rotating module 20 along a preset horizontal axis 30, thereby achieving unlocking. Because the two modules move relative to each other, the connection stability between components is easily affected by external forces or overuse, potentially leading to loosening or wear, thus reducing the device's durability. Furthermore, this unlocking method relies on precise control of the module's movement path; any deviation in the module's movement distance or mechanical wear will affect the accuracy of the limiting function, causing unlocking or locking failure. In this embodiment, however, during angle adjustment, the fixed module 10 does not shift along the preset horizontal axis 30; only the adapter 23 and part of the adjusting component 22 in the rotating module 20 move within the mounting cavity 211, separating the first limiting part 11 and the second limiting part 231. This allows for precise control of the movement path of the moving components and improves the stability between the modules.

[0073] This invention provides an angle adjustment device that divides multiple components into a fixed module 10 and a rotating module 20 according to their functions. This allows the two modules to be assembled in advance, eliminating the need for on-site adjustments of internal precision parts by the user. This ensures the stability of the internal structural connections of the modules and improves the success rate of user assembly. Simultaneously, this invention utilizes the movement of the adapter 23 and partial adjusting component 22 within the mounting cavity 211 in the rotating module 20 to separate the first limiting part 11 and the second limiting part 231. When the adapter 23 and partial adjusting component 22 move, the mounting base 21 remains stationary relative to the tabletop 70, and the fixed module 10 remains stationary relative to the table leg 80. This limits the movement range of the adapter 23 and partial adjusting component 22 to within the mounting cavity 211, thereby allowing for precise control of their movement paths and improving the stability between the fixed module 10 and the rotating module 20.

[0074] Furthermore, referring to Figure 5 and Figure 10The rotating module 20 includes a first elastic member 24 arranged along a preset horizontal axis 30; the first elastic member 24 is located between the mounting cavity 211 and the adapter 23; the adjusting member 22 is in the locked position, and the first elastic member 24 is compressed so that the first limiting part 11 and the second limiting part 231 are in upper limit engagement in the direction around the preset horizontal axis 30.

[0075] In this embodiment, the first elastic element 24 may be a spring or other structure with elastic restoring force, which is not limited here.

[0076] The first elastic element 24 has the function of ensuring the stability of the locked position. When the adjusting element 22 is in the locked position, the first elastic element 24 is in a compressed state. This compression generates a preset force, which enables the first limiting part 11 and the second limiting part 231 to achieve a reliable limiting engagement in the direction along the preset horizontal axis 30. This engagement ensures the stability and safety of the rotating module 20 in the locked state, preventing unexpected rotation or displacement.

[0077] Meanwhile, the first elastic element 24 ensures a stable and smooth switching process between the locked and unlocked positions. Due to the elastic properties of the first elastic element 24, the desktop angle adjustment device 100 can easily release its limiting state when the user needs to adjust the angle. When the user applies external force to compress / release the first elastic element 24, the rotating module 20 can move smoothly around the preset horizontal axis 30 path, ensuring the smoothness and controllability of the adjustment process.

[0078] Furthermore, referring to Figure 4 , Figure 5 , Figure 9 , Figure 10 , Figure 13 ,as well as Figure 14 The adapter 23 is provided with a first assembly groove 232 and a second assembly groove 233; the first elastic member 24 is adapted to be installed in the first assembly groove 232; and a portion of the adjusting member 22 is adapted to be installed in the second assembly groove 233.

[0079] In this embodiment, the first assembly slot 232 is adapted to install the first elastic member 24, ensuring that the first elastic member 24 is stably fixed within the first assembly slot 232, thus maintaining the smooth progress of the compression and release process. The second mounting slot 2131 is adapted to install a portion of the adjusting member 22, enabling the adjusting member 22 to form an adjustable linkage structure with the adapter 23, ensuring that both can maintain high-precision angle adjustment during the adjustment process.

[0080] The first assembly slot 232 and the second assembly slot 233 are simultaneously located on the adapter 23, enabling the adapter 23 to integrate dual functions, reduce the number of parts, and achieve a more compact structural design. At the same time, the adapter 23 achieves an integrated modular structure, reducing the coupling complexity between components and making the overall assembly and disassembly of the adapter 23 as a module simple and efficient.

[0081] In some embodiments, reference is made to Figure 13 and Figure 14 The adapter 23 has a plurality of first mounting slots 232, which are arranged around the second mounting slot 233.

[0082] Furthermore, the desktop angle adjustment device 100 includes a plurality of first elastic elements 24 and a plurality of limiting screws 94. The inner wall of the mounting cavity 211 is provided with an equal number of sleeves. The sleeves pass through the bottom wall of the first assembly groove 232 and are fixedly connected to the limiting screws 94. The first elastic elements 24 are sleeved on the sleeves and are located between the head of the limiting screws 94 and the bottom wall of the first assembly groove 232.

[0083] Furthermore, referring to Figures 12 to 14 The inner wall of the second assembly groove 233 and the adjusting member 22 are respectively provided with a first inclined surface 2331 and a second inclined surface 221; the first inclined surface 2331 and the second inclined surface 221 are both set at an angle to the preset horizontal axis 30; when the adjusting member 22 is in the locked position, the first inclined surface 2331 and the second inclined surface 221 are engaged in the upper limit cooperation in the direction around the preset horizontal axis 30; when the adjusting member 22 is in the unlocked position, the first inclined surface 2331 disengages from the second inclined surface 221, so that the first limiting part 11 disengages from the second limiting part 231.

[0084] In this embodiment, when the adjusting member 22 is in the locked position, the first inclined surface 2331 and the second inclined surface 221 cooperate with each other to provide a limiting function. When the adjusting member 22 is switched to the unlocked position, the first inclined surface 2331 disengages from the second inclined surface 221, thereby disengaging the first limiting part 11 and the second limiting part 231, and the unlocked state is achieved. This effectively reduces unnecessary friction and wear, ensures the smoothness of the adjustment process, and allows for easy unlocking and adjustment when the tabletop angle of 70° needs to be adjusted.

[0085] In some embodiments, the adjusting member 22 is provided with a plurality of limiting grooves 92, one of the inner wall surfaces of the limiting grooves 92 being a second inclined surface 221; the second assembly groove 233 is provided with a plurality of limiting bosses 93, each of which is provided with a first inclined surface 2331; the number of limiting bosses 93 and limiting grooves 92 corresponds one-to-one. In the locked position of the adjusting member 22, the limiting bosses 93 are placed in the limiting grooves 92, and the first inclined surface 2331 and the second inclined surface 221 are limited in the direction around the preset horizontal axis; when the adjusting member 22 switches from the locked position, the first inclined surface 2331 moves relative to the second inclined surface 221; when the first inclined surface 2331 disengages from the second inclined surface 221, the switching member 23 moves relative to the adjusting member 22 in the direction of the preset horizontal axis until the limiting bosses 93 disengage from the limiting grooves 92.

[0086] In one embodiment, reference is made to Figure 6 , Figure 7 , Figure 11 , Figure 12 , Figure 17 , Figure 18 The desktop angle adjustment device 100 also includes a fixing member 40; part of the fixing member 40 is placed in the mounting cavity 211 and is in upper limit engagement with the rotating module 20 in the direction along the preset horizontal axis 30, and is in rotational engagement with the rotating module 20 in the direction around the preset horizontal axis 30; the remaining fixing members 40 pass through the fixing module 10 and are in upper limit engagement with the fixing module 10 in the direction around the preset horizontal axis 30.

[0087] In this embodiment, a portion of the fixing member 40 is placed within the mounting cavity 211 and engages with the rotating module 20 at an upper limit in the direction of the preset horizontal axis 30. This arrangement ensures the stability of the rotating module 20 when rotating around the preset horizontal axis 30, effectively preventing loosening or displacement during desktop angle adjustment. The remaining portion passes through the fixing module 10 and engages with it at an upper limit in the horizontal axis direction, enabling the entire device to remain stable when adjusting the desktop angle and preventing accidental slippage or errors during the adjustment process.

[0088] In some embodiments, the fixing member 40 includes a cylindrical body 41 and a limiting member 42. One end of the cylindrical body 41 is provided with a plurality of limiting grooves 411 spaced apart along the circumference of the cylindrical body 41. The number of limiting grooves 411 corresponds one-to-one with the number of limiting ribs 12 of the fixing module 10, and the limiting grooves 411 and limiting ribs 12 cooperate one-to-one. The limiting member 42 is connected to the outer wall surface of the other end of the cylindrical body 41. The limiting member 42 can achieve limiting cooperation with the mounting base 21 and / or the adjusting member 22 in the horizontal axis direction.

[0089] In some embodiments, a pre-set horizontal axis 30 passes through the cylinder 41. This enhances the rotational stability of the desktop angle adjustment device 100 and also improves the compactness of the structure.

[0090] In one embodiment, reference is made to Figure 5 and Figure 14 The adapter 23 is provided with a third limiting part 234 extending in the direction of the preset horizontal axis 30; the inner wall surface of the mounting cavity 211 is provided with a fourth limiting part 2111 extending in the direction of the preset horizontal axis 30; the third limiting part 234 and the fourth limiting part 2111 are limited and engaged in the direction around the preset horizontal axis 30, and can slide in the direction of the preset horizontal axis 30.

[0091] In this embodiment, since the third limiting part 234 and the fourth limiting part 2111 are limited and engaged in the direction around the preset horizontal axis 30, and can slide in the direction of the preset horizontal axis 30, the cooperation between the two realizes the dual functions of angle control and position adjustment.

[0092] The third limiting part 234 and the fourth limiting part 2111 form a stop-fit ​​structure. When the adapter 23 rotates around the horizontal axis to a set angle, the two parts contact and limit each other, avoiding damage to the components caused by excessive rotation and improving safety. At the same time, the third limiting part 234 and the fourth limiting part 2111 can slide in the direction of the preset horizontal axis 30, which enhances the stability of the adapter 23 moving in the direction of the preset horizontal axis 30.

[0093] In some embodiments, the third limiting part 234 and the fourth limiting part 2111 can be a linear protrusion 2112 and a guide rail groove 2341; they can be an inverted T-shaped boss structure and a matching T-shaped limiting groove; or they can both be linear protrusions 2112.

[0094] In one embodiment, reference is made to Figures 11 to 13 The adjusting member 22 includes a main body 222 and a gripping part 223 connected to the main body 222. The main body 222 is placed in the mounting cavity 211. Part of the gripping part 223 is exposed in the mounting cavity 211 along a first direction. The first direction intersects the direction of the preset horizontal axis 30. The desktop angle adjusting device 100 also includes a second elastic member 50 disposed between the gripping part 223 and the table 70. The second elastic member 50 is compressed to make the adjusting member 22 be in a locked position.

[0095] In this embodiment, the main body 222 is disposed inside the mounting cavity 211 and cooperates with the adapter 23 in the rotating module 20; the gripping part 223 is connected to the main body 222, extends along the first direction and is partially exposed outside the mounting cavity 211, which facilitates user operation.

[0096] It is understandable that part of the grip 223 is located inside the mounting cavity 211, and part of the grip 223 is exposed outside the mounting cavity 211.

[0097] To enhance the automatic reset capability during operation, a second elastic element 50 is provided between the grip 223 and the table 70. Under normal operating conditions, this element is in a compressed state, thereby pushing the adjustment element 22 to a stable locked position. During operation, the user only needs to push the grip 223 to overcome the elastic force of the second elastic element 50 to achieve the adjustment function.

[0098] Furthermore, the top surface of the exposed grip 223 serves as a stop plane. When adjusting the angle of the tabletop 70, the user places both hands on either side of the tabletop 70, so that the tabletop 70 and the grip 223 are in their hands; then, the fingers press the grip 223 so that the stop plane on the grip 223 abuts against the bottom surface of the tabletop 70. This means that the desktop adjustment device 100 is in the unlocked state, and the user can freely adjust the angle of the tabletop 70.

[0099] Furthermore, referring to Figure 6 , Figure 7 as well as Figure 13 The gripping part 223 and the main body part 222 are respectively provided with a first through hole 2221 and a second through hole 2231. The first through hole 2221 and the second through hole 2231 are coaxially arranged along the direction of the preset horizontal axis 30. The mounting cavity 211 has an opening away from the fixing module 10. The desktop angle adjustment device 100 also includes a cover 60 that covers the opening. The cover 60 is provided with a fixing rod 61 protruding towards the mounting cavity 211. The fixing rod 61 passes through both the first through hole 2221 and the second through hole 2231.

[0100] In this embodiment, the first through hole 2221 and the second through hole 2231 are coaxially arranged along the preset horizontal axis 30 to achieve precise alignment. The cover 60 is used to cover the opening of the mounting cavity 211. The cover 60 and the mounting base 21 can be detachably or connected in a flip-top manner, etc., and the specific connection method is not limited here. The fixing rod 61 protrudes from the inner side of the cover 60, and the fixing rod 61 passes through the first through hole 2221 and the second through hole 2231, forming a coaxial insertion structure with the grip 223 and the main body 222. This ensures that when the grip 223 and the active part rotate around the preset horizontal axis 30, the fixing rod 61 is always the central axis, thereby improving the smoothness and accuracy of the desktop angle adjustment and avoiding structural interference or shaking caused by multi-axis or eccentric rotation.

[0101] In addition, integrating the fixing rod 61 onto the cover 60 simplifies the installation process. Users or production personnel can complete the insertion of the fixing rod 61 while closing the cover 60, without the need for separate alignment of the pin or insertion of tools, which significantly improves assembly efficiency and ease of maintenance.

[0102] This utility model also proposes a table 200, as shown in the reference. Figure 1 and Figure 2The table 200 includes a tabletop 70, two table legs 80, and two desktop angle adjustment devices 100 as described in any of the above embodiments. The specific structure of the desktop angle adjustment device 100 is as described in the above embodiments. Since the table 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The two table legs 80 are spaced apart along a preset horizontal axis 30; the rotating module 20 of the desktop angle adjustment device 100 is fixedly connected to the tabletop 70, and the fixing module 10 of the desktop angle adjustment device 100 is connected to the table legs 80; in the unlocked position of the adjusting member 22 of the desktop angle adjustment device 100, the tabletop 70 can rotate relative to the table legs 80.

[0103] In this embodiment, the tabletop 70 is supported by two angle adjustment devices set on both sides of the horizontal axis. When the user operates the adjustment component 22 to put it in the unlocked position, the tabletop can rotate freely around the preset horizontal axis 30, thereby realizing flexible switching of the tabletop tilt angle according to different usage scenarios (such as writing, drawing, reading, presentation, etc.).

[0104] Furthermore, the table leg 80 includes a foot 81 and a foot pad 82 connecting the foot 81; the foot pad 82 is elongated, and the width of the foot pad 82 at the connection with the foot 81 is smaller than the width of the two ends of the foot pad 82 in a first direction; the first direction intersects with the preset horizontal axis 30 direction.

[0105] In this embodiment, the foot pad 82 is configured as a long strip structure that extends in the first direction (intersecting with the preset horizontal axis 30 direction), so that the desktop device can obtain a larger ground contact area during the horizontal axis adjustment process, thereby effectively improving the overall stability of the desktop at each adjustment angle and preventing tilting, shaking or tipping.

[0106] Furthermore, the side edges of the foot pad 82 are rounded or curved. This prevents the foot pad 82 from accidentally injuring the user when the table 200 is moved or adjusted, and also prevents the sharp edges of the foot pad from snagging or damaging the material when the table 200 is placed on textiles or soft materials.

[0107] The foot pad 82 and the foot 81 can be detachably connected, for example, by screws, clips, or slots. The specific connection method between the foot pad 82 and the foot 81 is not limited here. When the foot pad 82 and the foot 81 are detachably connected, the foot pad 82 can be replaced individually after damage or wear, greatly improving product maintainability, reducing overall replacement costs, and also facilitating the customization of foot pad 82 components of different materials or shapes for different scenarios. The foot pad 82 and the foot 81 can also be detachably connected.

[0108] In one embodiment, reference is made to Figure 1 and Figure 2 The tabletop 70 is provided with a stop 71 extending along the preset horizontal axis, and the top surface of the stop 71 is raised in the middle region of the preset horizontal axis.

[0109] A stop 71 is also provided on the side of the tabletop 70 closest to the user. The stop 71 prevents books, notebooks, tablets, and other items placed on the tabletop from falling when it is tilted. The top surface of the stop 71 is raised in the middle area along a predetermined horizontal axis, making the side areas of the top surface of the stop 71 relatively lower than the raised area, forming a sloping structure. This effectively prevents items from slipping while ensuring user comfort and reducing hand fatigue during use.

[0110] Furthermore, the mounting base 21 of the desktop angle adjustment device 100 includes a first assembly part 212 and a second assembly part 213 arranged along a preset horizontal axis 30. The second assembly part 213 is located inside the first assembly part 212. The first assembly part 212 is provided with a mounting cavity 211 for the desktop angle adjustment device 100, and the bottom surface of the first assembly part 212 away from the tabletop 70 is a resting plane 2121. The fixing module 10 of the desktop angle adjustment device 100 is connected to the second assembly part 213.

[0111] The table leg 80 is rotatably connected to the fixed module 10 of the tabletop angle adjustment device 100, so as to have an unfolded position and a folded position; in the unfolded position, the table leg 80 is set at an angle to the tabletop 70; in the folded position, the table leg 80 rotates to be close to or abut against the tabletop 70, and the table leg 80 is lower than or flush with the resting plane 2121 in the vertical direction; the preset horizontal axis 30 direction, the first direction and the vertical direction intersect each other.

[0112] In this embodiment, the fixing module 10 of the desktop angle adjustment device 100 is integrated with the second assembly part 213 of the mounting base 21, and the table leg 80 is rotatably connected to the fixing module 10. Through the integrated structural layout, the function of adjustable desktop angle is ensured, while also having the advantage of foldable table leg 80 for storage, significantly improving the overall multifunctionality of the table 200.

[0113] Since the table legs 80 can rotate from the unfolded position to the folded position, when the table 200 is not in use, the table legs 80 can be close to or abut against the bottom surface of the tabletop 70, and are lower than or flush with the resting plane 2121 in the vertical direction, which significantly reduces the height occupied by the table 200, making it convenient for users to stack, store or carry. It is especially suitable for occasions such as multifunctional classrooms, flexible office scenarios and home places where the table 200 needs to be folded frequently.

[0114] In addition, refer to Figure 4Alternatively, the shelf 2121 can be placed on the ground or other supporting surface. In this case, the folded table 200 can be used as a small table.

[0115] In some embodiments, the fixing module 10 is provided with a receiving cavity 13, which has a first opening 131 facing away from the first assembly part 212 and a downward-facing second opening 132, with the first opening 131 communicating with the second opening 132. The table legs are rotatably connected to the inner wall of the receiving cavity 13. The first opening 131 and the second opening 132 are used to avoid the table legs, so that the table legs can switch between the unfolded and folded positions. The design of the receiving cavity 13 not only optimizes the rotation space of the table legs but also enhances the structural stability.

[0116] Furthermore, the two inner wall surfaces of the accommodating cavity 13 adjacent to the first opening are provided with a protrusion 91. In the unfolded state, the protrusion 91 can restrict the table leg 80 from rotating toward the tabletop 70, so as to maintain a fixed angle between the tabletop 70 and the table leg 80. When switching from the unfolded state to the folded state, the accommodating cavity 13 can deform appropriately, so that the table leg 80 can rotate to abut against the tabletop 70.

[0117] In some embodiments, reference is made to Figure 9 The second assembly part 213 includes a mounting groove 2131, in which a portion of the fixing module 10 and a portion of the table legs 80 are placed.

[0118] Furthermore, referring to Figures 8 to 12 The top wall of the mounting groove 2131 is provided with a clearance hole 2132, and the fixing module 10 is provided with a stop protrusion 14. In the initial position (i.e., when the tabletop 70 has not been angled), the stop protrusion 14 abuts against the wall of the clearance hole 2132 on the side closer to the person. Thus, in the unlocked position of the adjusting member 22, the side of the tabletop 70 closest to the person can only rotate downward relative to the ground, and cannot rotate upward relative to the ground.

[0119] In use, the user operates the grip 223 to compress the second elastic member 50, at which time the grip 223 moves relative to the tabletop 70; at the same time, the adjusting member 22 and the adapter 23 located in the mounting cavity 211 rotate relative to each other, and the limiting relationship between them is released; while the adapter 23 rotates around the preset horizontal axis, it moves along the preset horizontal axis, thereby separating the first limiting part 11 on the adapter 23 from the second limiting part 231 on the fixing module 10; at this time, the user can adjust the angle between the tabletop and the table legs as needed.

[0120] It is worth noting that during the separation of the first limiting part 11 and the second limiting part 231, the mounting base 21 is stationary relative to the tabletop 70, and the fixing module 20 is stationary relative to the table leg 80.

[0121] In some embodiments, reference is made to Figure 1 and Figure 2 The legs include a telescopic structure, allowing for adjustment of leg length.

[0122] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
