[0040] Example 1

[0041] like Figures 1 to 12 The portable tabletop structure shown includes: a base 1, a rotating support assembly 2, and a tabletop assembly 3. The base 1 has a pressure-applying member 11 extending horizontally, used to maintain the stability of the base 1 under external pressure. The rotating support assembly 2 includes a support base 21 and a rotating support member 22. The support base 21 is vertically connected to the base 1, and the rotating support member 22 includes a vertical connecting portion 22a and a horizontal connecting portion 22b. The vertical connecting portion 22a is rotatably connected to the support base 21. The tabletop assembly 3 includes a tabletop body 31 and a horizontal support member 32. The horizontal support member 32 and the horizontal connecting portion 22b are rotatably connected to each other on a horizontal plane, and the tabletop body 31 and the horizontal support member 32 are rotatably connected to each other on a vertical plane. Figures 1 to 5 As shown, the base 1 is the basic part of the structure, and the pressure-applying component 11 on it ensures the stability of the tabletop and prevents wobbling through external pressure. It should be noted that the pressure-applying component 11 can be a horizontal plate or a strip structure, etc., and its connection to the base 1 can be a threaded connection or a sliding groove, etc. Regarding the material selection of the pressure-applying component 11, metal materials with strong load-bearing capacity and durability, such as stainless steel and aluminum alloy, can be used. Filling materials can also be added inside to improve stability. Furthermore, to increase friction with the ground, the contact surface of the pressure-applying component 11 may be covered with rubber or soft padding material, which provides better grip and prevents slippage. The horizontal support component 32 is connected to the horizontal connecting part 22b of the rotating support component 22, allowing the tabletop body 31 to be adjusted horizontally through relative rotation, increasing the ease of use of this invention. This invention, through its rotating and adjustable connection method, ensures easy disassembly, carrying, and adjustment, making it suitable for mobile use. The rotating mechanism of the vertical connecting part 22a and the horizontal connecting part 22b enables the tabletop body to rotate first and then turn, thus meeting different usage needs, such as tilting the tabletop to improve the viewing or writing angle. The design of the pressure-applying component 11 ensures safety and comfort during use. This product can be easily combined with chairs, sofas, or beds, using the weight of the chair, sofa, or bed itself to ensure a stable base that does not move, guaranteeing reliability and convenience during use.

[0042] In some embodiments of the utility model, base 1 includes main support beam 12, pressure applying part 11 is vertically arranged at one end of main support beam 12, and support base 21 is vertically connected to the other end of main support beam 12. Figure 6 As shown in the drawings, main support beam 12 provides the basic support structure of base 1, which bears the applied external pressure and provides a stable connection point for other components. Pressure applying part 11 forms a right angle with main support beam 12, and the direction of the applied pressure is perpendicular to the axis of main support beam 12. In this way, pressure applying part 11 transmits external pressure to main support beam 12 and makes base 1 more stable during use. The material of main support beam 12 and support base 21 can also be the same as that of pressure applying part 11, or can be selected according to the requirements of the use scenario. Figure 10 As shown in the drawings, during user standing use, only need to step on pressure applying part 11 to reliably fix the product.

[0043] Further, base 1 also has first pressure receiving plate 11a, which is fixed to the bottom of the corner between main support beam 12 and pressure applying part 11 and extends towards the inside of the corner, for receiving the pressure of table legs, sofa legs or bed legs. Figure 6 As shown in the drawings, first pressure receiving plate 11a is arranged at the bottom of the corner between main support beam 12 and pressure applying part 11 and extends towards the inside of the corner. This is a region with relatively large pressure in the structure in terms of mechanics, and the arrangement of first pressure receiving plate 11a can effectively enhance the load-bearing capacity of the structure. The main function of first pressure receiving plate 11a is to receive the pressure from the legs of furniture. In the use scenario, the weight and stress of furniture such as table legs, sofa legs or bed legs are transmitted to base 1. First pressure receiving plate 11a absorbs and disperses these pressures through its solid structure, thereby preventing other components of base 1 from deforming or losing stability due to excessive pressure. Figure 11 and Figure 12 As shown in the drawings, the thickness of first pressure receiving plate 11a is set to be relatively thin, generally 2-5 mm. This thickness setting ensures that even when a corner of furniture such as table legs, sofa legs or bed legs is pressed on the pressure receiving plate, it will not affect the use experience of other furniture.

[0044] In addition, the bottom of the end of main support beam 12 away from pressure applying part 11 also has second pressure receiving plate 12a, which is vertically arranged with main support beam 12 and has the same orientation as pressure applying part 11. Please continue to refer to Figure 6The second pressure bearing plate 12a is opposite to the pressure applying piece 11 at the other end of the main support beam 12, so that the other end of the base 1 also has the same load bearing capacity, further ensuring stability. Like the first pressure bearing plate 11a described above, it can be connected with the main support beam 12 by bolt fixation, welding or other stable ways to ensure that it will not loosen during long-term use; the material can be selected from steel, aluminum alloy or high-strength plastic, etc. to ensure that it can withstand the pressure during long-term use and is not easy to deform or damage.

[0045] Further, the bottom of the support seat 21 also has a support leg 21a extending radially, and the other end of the support leg 21a is connected with the second pressure bearing plate 12a. Please continue to refer to Figure 6 The support leg 21a extends outward at a certain angle, so that the support leg 21a can effectively expand the support area and improve the stability and support force of the overall structure. The radially extending support leg 21a can disperse external pressure to a larger range, thereby enhancing the support effect. The support leg 21a also forms a force transmission path with the second pressure bearing plate 12a, which can effectively bear the pressure transmitted from the second pressure bearing plate 12a and uniformly disperse it to other parts of the base 1 or the ground. When selecting the material of the support leg 21a, high-strength metal materials or composite materials with good strength can be selected, which can withstand long-term load and ensure the durability and stability of the support leg 21a.

[0046] In some embodiments of the present application, the connection height of the rotary support 22 and the support seat 21 is adjustably arranged. As shown in Figure 7 and Figure 8 The connection point position of the rotary support 22 and the support seat 21 can be adjusted up and down within a certain range, so as to change the relative height of the rotary support 22. This adjustment mode can be realized by adjusting bolts, sliding grooves, buckle structures, etc. The adjusting components need to have certain wear resistance and fatigue resistance, such as stainless steel, aluminum alloy or engineering plastic, which can withstand repeated adjustment during long-term use without being easily damaged.

[0047] Specifically, in some embodiments of the present application, the main body of the support seat 21 is tubular, the vertical connecting part 22a extends into the inside of the support seat 21 and is movably arranged in the axial direction of the support seat 21, and the top of the support seat 21 also has a first locking mechanism 21b for adjusting and fixing the position of the vertical connecting part 22a. Please continue to refer to Figure 7 and Figure 8The tubular support base 21 enables the support base 21 to accommodate the internal vertical connecting part 22a and allow relative movement within the tube. The first locking mechanism 21b is a device for fixing the position of the vertical connecting part 22a relative to the support base 21. After the vertical connecting part 22a is adjusted, its position can be locked to prevent loosening or displacement during use. The first locking mechanism 21b can take various forms, such as bolts, buckles, spring locks, etc. The user can adjust the vertical connecting part 22a to the desired position by sliding it up and down. The position of the vertical connecting part 22a can usually be freely adjusted within a certain range to meet the needs of different heights or angles; once the vertical connecting part 22a is adjusted to the appropriate position, the user can fix it in that position by activating the first locking mechanism 21b, ensuring that it does not accidentally move during use. The tubular structure of the support base 21 body and the adjustable design of the vertical connecting part 22a make the entire structure highly flexible and can be adjusted in height as needed. By providing the first locking mechanism 21b at the top of the support base 21, the stability of the vertical connecting part 22a after adjustment can be ensured, avoiding movement due to external forces. The embodiments of the present application are suitable for furniture and equipment that need to adjust the height or angle, improving the stability, operability and adaptability of the structure.

[0048] In some embodiments of the present application, the horizontal support 32 and the horizontal connecting part 22b are connected by a damping rotation. As shown in Figure 9 The damping rotation connection provides a smooth rotation process, avoiding rapid movement during rotation, making the adjustment of the desktop or support structure more gentle and improving the user experience. The damping design effectively reduces the vibration or noise generated during rotation, especially in situations that require frequent adjustment. The damping setting reduces vibration and noise during rotation, improves overall user experience, and avoids instability or safety issues caused by rapid rotation. For situations that require angle or height adjustment, it can improve the comfort and reliability of operation.

[0049] Specifically, in some embodiments of the present application, the middle part of the horizontal support 32 has a first flange 32a arranged perpendicular to the horizontal support 32, and the horizontal connecting part 22b has a second flange 22b1 arranged vertically, and a damping rotation shaft 33 is connected between the first flange 32a and the second flange 22b1. Please continue to refer to Figure 9, the first flange 32a provides a fixed point to connect the horizontal support 32 and the damping rotating shaft 33, and the second flange 22b1 and the first flange 32a are connected through the damping rotating shaft 33. This design provides an abutting contact surface between the two flanges, enhancing the reliability and durability of the rotating connection. The flange material can be made of metal material, which has high strength and durability, and can withstand the load and stress during rotation. The damping rotating shaft 33 is used to connect the first flange 32a and the second flange 22b1, so that the horizontal support 32 and the horizontal connecting part 22b can rotate relatively, but provide damping effect during rotation, slow down the rotation speed, avoid too fast or too violent rotation, and absorb certain energy during rotation, thereby reducing vibration and noise. The damping rotating shaft 33 can be made of high-strength steel or alloy, and contains appropriate damping elements such as hydraulic oil or friction material inside to achieve the damping effect of rotation. The design of the damping rotating shaft 33 connected between the first flange 32a and the second flange 22b1 provides flexible rotation and smooth control of the structure, which can effectively control the speed of rotation, reduce vibration and noise, and improve the stability and durability of the overall structure. Through the setting of the damping rotating shaft 33, the desktop body 31 can be rotated to any desired angle and then stopped, thereby improving the convenience of adjustment.

[0050] In addition, the horizontal support 32 is arranged on the center line of the desktop body 31, and the desktop body 31 further has a second locking mechanism 34, which is wrapped around the horizontal support 32 near the two ends. The second locking mechanism 34 is used to adjust the rotation angle of the desktop body 31 relative to the horizontal support 32. Please continue to refer to Figure 9, the horizontal support 32 is arranged on the center line of the table plate body 31, that is, horizontally arranged along the central axis of the table plate, which enables the support to uniformly support the entire table plate body 31 in the horizontal plane, ensuring the balance and stability of the table plate. The second locking mechanism 34 is arranged near the two ends of the horizontal support 32, which aims to control the rotation range and adjustment angle of the table plate, and can lock the angle of the table plate when needed to prevent the table plate from tilting or rotating unintentionally. The second locking mechanism 34 is designed to allow users to adjust the rotation angle of the table plate body 31 relative to the horizontal support 32 as needed. It should be noted that the second locking mechanism 34 can lock the table plate body 31 in the desired position after adjusting the angle, thereby preventing accidental rotation of the table plate during use; the second locking mechanism 34 has a surrounding structure that adjusts and locks the angle through clamping, pressing, or clamping. The second locking mechanism 34 is similar in principle to the first locking mechanism 21b, both of which reduce the clamping gap of the clamp by tightening the bolt, thereby fixing the clamped object, and vice versa, which can unload the clamping force to facilitate adjustment. In addition, the second locking mechanism 34 can be adjusted in a rotating manner, and users only need to rotate the locking device to achieve fine adjustment of the desktop angle; it can also have a manual or automatic locking function, which is usually achieved through a knob, button, or lever, while automatic locking may rely on springs or friction materials to automatically lock the angle at the set position. The design of the second locking mechanism 34 can set an angle limit to avoid excessive tilting of the desktop and ensure safety during use, and can use gears, cams, friction plates, and other elements to ensure precise control and stable fixation when adjusting the angle.

In the second embodiment of the present application, the structure of the base 1 is improved; it should be noted here that the base 1 in the present application has multiple forms, which can be the L-shaped structure formed by the main support beam 12 and the pressure applying member 11 in the first embodiment, or other structure forms. In the second embodiment of the present application, please refer to Figure 13 , which adopts an I-shaped structure, of course, the I-shaped here refers to eccentric, more towards the user side, in the second embodiment of the present application, the first pressure receiving plate 11a is also arranged at the included angle of the main beam and the pressure applying member 11, so as to realize the fixation of the portable table plate through external gravity.

[0053] In the second embodiment of the utility model, as shown in Figure 14 and Figure 15 The base 1 bottom also has height adjusting piece 11b, height adjusting piece 11b distributes at the corner of base 1, for adjusting the placing flatness of base 1. The height adjusting piece 11b here has multiple forms, for example can be the turntable screwing with base 1 through stud, by rotating the turntable to make the distance of turntable bottom and base 1 change, thereby can fine tune the height when the ground is uneven, make the adaptation ability of this portable table board structure to the terrain stronger.
