The annular outer plate and the rotating inner plate of the support structure are connected or separated by a gear ring and a positioner. The upper ends of the V-shaped support rods of each group of variable height supports are connected to the annular outer plate and the rotating inner plate, respectively. Therefore, by rotating the tabletop to make the support rods of each variable height support more inclined, the height of the tabletop can be lowered. Conversely, by rotating the tabletop in the opposite direction to make the support rods more upright, the height of the tabletop can be raised. By operating the positioner to engage or disengage with the gear ring, the coffee table can be fixed at the current height. Therefore, this height-adjustable coffee table can be conveniently raised and lowered, improving the convenience of use.

[0013] By installing an energy accumulator between the tabletop and the rotating inner panel, energy is stored during the process of lowering the coffee table and released when the tabletop height is increased. This improves the ease of increasing the height of the coffee table. Attached Figure Description

Detailed Implementation

[0016] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0017] Please see Figure 1 , Figure 2 and Figure 3 The present invention relates to a telescopic coffee table, comprising a tabletop 1 and a variable-height support 2, with a support structure provided between the tabletop 1 and the variable-height support 2. The shape of the variable-height support 2 can be controllably changed, thereby changing the height of the tabletop 1.

[0018] The supporting structure includes an annular outer plate 3, inside which is a rotating inner plate 5. The rotating inner plate 5 and the annular outer plate 3 can rotate relative to each other. The tabletop 1 is fixedly connected to the annular outer plate 3. A rotary bearing 11 is installed between the tabletop 1 and the rotating inner plate 5. A toothed ring 10 with an outer ring tooth is installed on the rotating inner plate 5. A positioner 8 for fixing and releasing the toothed ring 10 is installed on the annular outer plate 3.

[0019] In this embodiment, an annular sealing edge 4 is also installed on the outer edge of the annular outer plate 3. The annular sealing edge 4 seals the gap between the tabletop 1 and the annular outer plate 3. In this way, the user's hand will not be put into the space between the tabletop 1 and the annular outer plate 3 during operation, which improves the safety of operation and avoids the problem of movement jamming by preventing foreign objects from entering this space.

[0020] Please see Figure 3 and Figure 5 It can be seen that: In this embodiment, the rotary bearing 11 includes an inner bearing ring and an outer bearing ring. The inner bearing ring is fixedly connected to the tabletop 1, and the outer bearing ring is fixedly connected to the rotating inner plate 5. The function of setting the rotary bearing 11 is to improve the smoothness of the operation when the tabletop 1 and the rotating inner plate 5 rotate relative to each other.

[0021] Please see Figure 3 , Figure 4 and Figure 7 It can be seen that: In this embodiment, the positioner 8 includes two side bases 8-1 fixedly connected to the annular outer plate 3. A positioning plate 8-2 with teeth on its inner edge that can move radially is provided between the two side bases 8-1. The teeth on the positioning plate 8-2 cooperate with the teeth on the gear ring 10. A lever plate 8-4 is also provided on the positioning plate 8-2. A spring 8-3 that provides a reset force to the lever plate 8-4 is installed between the two side bases 8-1. The lever plate 8-4 is exposed downward through a window provided on the annular outer plate 3.

[0022] During operation, manually moving the lever 8-4 radially outward causes the positioning plate 8-2 to move radially outward as well. The teeth of the positioning plate 8-2 separate from the teeth on the gear ring 10, disengaging the outer annular plate 3 and the rotating inner plate 5, allowing them to rotate relative to each other. At this point, the spring 8-3 extends further. When the lever 8-4 is released, under the elastic force of the spring 8-3, the positioning plate 8-2 moves radially inward until the teeth of the positioning plate 8-2 engage with the teeth on the gear ring 10. This merges the outer annular plate 3 and the rotating inner plate 5 into one unit, preventing further relative rotation between them.

[0023] An energy storage device 7 is installed between the tabletop 1 and the rotating inner panel 5. The function of the energy storage device 7 is to store energy when the tabletop height is lowered and the variable height support 2 becomes shorter, and to release energy when the tabletop height is raised and the variable height support 2 becomes higher, which makes raising the coffee table easier.

[0024] Please see Figure 5 and Figure 6 It can be seen that: A central sleeve 6, open at both the top and bottom, is installed in the middle of the rotating inner plate 5. An accumulator 7 is installed and fixed inside this central sleeve 6. The accumulator 7 includes a coil spring support plate 7-2 fixed to the central sleeve 6 and a coil spring box 7-5. A hole is provided in the center of the coil spring support plate 7-2, and a coil spring central shaft 7-3 is provided within the hole. A coil spring (not shown in the figure, but located inside the coil spring box) is provided between the coil spring central shaft 7-3 and the coil spring box 7-5. A central mounting plate 7-4 is installed at the upper end of the coil spring central shaft 7-3 and is fixedly connected to the tabletop 1. A base plate 7-1 is installed at the lower end of the coil spring central shaft 7-3.

[0025] In this embodiment, a mounting flange 6-1 is provided in the middle of the inner wall of the central sleeve 6. The edge of the coil spring support plate 7-2 of the accumulator 7 overlaps with the mounting flange 6-1 and is fixedly connected by bolts. The center mounting plate 7-4 and the center plate 7-1 are fixedly connected to the upper and lower ends of the coil spring central shaft 7-3 by screws respectively. The bottom plate 7-1 can close the bottom opening of the central sleeve 6 to prevent personnel limbs and foreign objects from entering the internal space upward.

[0026] Please see Figure 2 and Figure 8 It can be seen that: The variable height support 2 includes a central seat 2-1, and multiple base frames 2-2 are installed on the outside of the central seat 2-1. Two support rods 2-3 arranged in a V-shape are installed at the outer end of each base frame 2-2. The upper end of one support rod 2-3 is connected to the annular outer plate 2, and the upper end of the other support rod 2-3 is connected to the outer edge of the rotating inner plate 5.

[0027] In this embodiment, the variable height support 2 includes three base frames 2-2 arranged at equal angular intervals along the axial direction. The lower end of the support rod 2-3 is connected to the outer end of the base frame 2-2 via a ball joint mechanism, and the upper end of the support rod 2-3 is connected to the annular outer plate 3 or the rotating inner plate 5 via a ball joint mechanism. Specifically, the ball sleeve of the lower ball joint mechanism is fixedly connected to the outer end of the base frame 2-2, and the ball sleeve of the upper ball joint mechanism is fixedly connected to the annular outer plate 3 or the rotating inner plate 5 respectively. Figure 2 The image shows the maximum height. When the height of the coffee table needs to be lowered, unlock it and press down on the tabletop 1 while rotating it. Then, one of the two support rods 2-3 arranged in a V-shape will fall to the left and the other to the right, reducing the overall height. Conversely, after unlocking, rotate the tabletop 1 while lifting it, and each support rod 2-3 will become more upright. This adjustment process can be called "up and down extension".

[0028] In this embodiment, a flat central groove 1-1 is provided at the center of the bottom of the desktop 1, and the central mounting plate 7-4 of the energy accumulator 7 is located within the central groove 1-1. In this embodiment, multiple mounting slots 1-2 are also provided on the bottom surface of the desktop 1, and channel steel 9 for improving structural strength is installed in each mounting slot 1-2. The overall structural strength of the desktop is improved by installing the channel steel 9, which is fixedly connected to the desktop 1 with screws. It is conceivable that the reinforcing structure of the desktop 1 is not limited to the structural form shown in the figure. For example, the mounting slot 1-2 can be a circular groove arranged on the bottom surface of the desktop 1, and the reinforcing channel steel can be machined into a suitable circular shape.

[0029] How to use: Figure 1 The diagram shows the structure of the coffee table in its highest position. To lower the coffee table, first, operate the locator 8 to release the connection between the outer ring panel 3 and the rotating inner panel 5. After unlocking, rotate the table while pressing down on the tabletop 1 until it reaches the desired height. The variable height support 2 will then change shape. During this process, the accumulator 7 stores energy, releasing the locator 8 and reconnecting the outer ring panel 3 and the rotating inner panel 5, thus maintaining the coffee table in its current state. To raise the tabletop 1, first, operate the locator 8 to release the connection between the outer ring panel 3 and the rotating inner panel 5. After unlocking, rotate the tabletop 1 while raising it until it reaches the desired height. The variable height support 2 will then change shape. During this process, the accumulator 7 releases energy, releasing the locator 8 and reconnecting the outer ring panel 3 and the rotating inner panel 5, thus maintaining the coffee table in its current state.
