Four bayonet holes 15 are provided on the upper surface of the ring frame 13. The four bayonet holes 15 are all connected to the inside of the turn rail 14. A block 16 is slidably connected to the inside of the turn rail 14. A U-shaped frame 17 is fixed to one end of the block 16 away from the ring frame 13. A support rod 18 is rotatably connected to the inside of the U-shaped frame 17. A tabletop 19 is provided inside the plate groove 4.

[0046] A rotation groove 20 is provided on the lower surface of the table top 19, and the top end of the support rod 18 is rotatably connected to the inside of the rotation groove 20. A fixing block 21 is fixed to the front of the lower surface of the ring frame 13, and a latch 22 is penetrated inside the fixing block 21. Two insertion holes 23 are provided on the front of the outer surface of the support tube 2, and the rear end of the latch 22 is plugged into the insertion hole 23 located below.

[0047] An annular groove 24 is provided below the outer surface of the support tube 2, and two grooves 25 are provided through the bottom of the support tube 2. A rotating ring 27 is rotatably connected inside the annular groove 24, and a bottom block 26 is inserted inside the groove 25. Both bottom blocks 26 are fixedly connected to the base 30. A clamping groove 31 is provided inside the bottom block 26, and two bottom grooves 28 are provided on the lower surface of the rotating ring 27. A clamping strip 29 is inserted inside the clamping groove 31, and the clamping strip 29 is fixedly connected to the inner wall of the bottom groove 28.

[0048] The outer surface of the support tube 2 is located below the four first support plates 7 and fixed with limit blocks 32;

[0049] The lower surface of the table top 19 is symmetrically provided with first mortises 33, and the ends of the two first mortises 33 away from the main board 1 are extended to the outer surface of the table top 19, the outer surface of the first support plate 7 is provided with third mortises 38 on both sides, and the outer surface of the second support plate 12 is provided with second mortises 34 on both sides, and the second mortises 34 and the third mortises 38 are slidably connected with the second tenon 36 inside, and the first tenon 35 is slidably connected inside the first mortise 33, and a support block 37 is fixedly connected between the first tenon 35 and the second tenon 36;

[0050] The opposite ends of the second support plate 12 and the first support plate 7 are both inclined structures, and the second support plate 12 fits the first support plate 7, the slide rail 11 is a T-shaped structure, and the block 16 is an L-shaped structure;

[0051] The lower surface of the table top 19 fits with the upper surfaces of two adjacent support blocks 37;

[0052] The upper surface of the second support plate 12, the upper surface of the main board 1, the upper surface of the table board 19, the upper surface of the first support plate 7, and the upper surface of the second support plate 12 are all in the same horizontal plane;

[0053] During disassembly, the ring frame 13 is rotated to move the bayonet 15 to the top of the corresponding block 16, and then the U-shaped frame 17 can be lifted to disassemble the block 16 and the ring frame 13, so that the table board 19 component is separated from the main structure;

[0054] The four table tops 19 and the surface of the main board 1 are joined together with the four first support boards 7 and the second support boards 12 to form a larger tabletop for multiple people to use.

[0055] like Fig.13 , Fig.14 As shown, the coffee table is folded through operation, the desktop area becomes smaller, and the desktop with adjustable size can adapt to different usage needs.

[0056] When disassembling, rotate the swivel 27 to drive the two clamping strips 29 to rotate. The clamping strips 29 rotate away from the clamping slots 31, and the connection between the bottom block 26 and the swivel 27 is lost. At this time, the main board 1 and the support tube 2 can be lifted to make the internal middle column 3 slide out, so as to be separated and disassembled from it, so that the two main parts of the inner and outer parts, which are also in an upper and lower position relationship, are separated and disassembled. At the same time, as the middle column 3 is removed, the ring plate 9 is also separated from the four arc grooves 8, so that the arc grooves 8 and the ring plate 9 are limited. At this time, the plug plate 6 can be pulled out of the slot 5, so that the first support plate 7, the second support plate 12 and other structures can be disassembled, and this part can be quickly separated; when assembling, just follow the reverse steps.

[0057] like Figure 4As shown, the support block 37 connects the first support plate 7 with the second support plate 12 through the second tenon 36, and the support block 37 connects the table top 19 with the two support plates through the first tenon 35 above, so that the table top of the coffee table in the unfolded state is more stable;

[0058] When the coffee table needs to be folded, the support block 37 needs to be slid to make the second tenon 36 slide out of the second mortise groove 34 and the first tenon 35 slide out of the first mortise groove 33, and then the table top 19 is moved to the upper surface of the main board 1. After the table top 19 releases the limit of the support block 37, it is necessary to pull out the latch 22 to release the limit of the ring frame 13. The ring frame 13 can be moved with the rise of the table top 19 under the drive of the support rod 18. When the table top 19 is placed on the upper surface of the main board 1, the latch 22 is inserted into the corresponding upper socket 23 to fix the ring frame 13. At this time, the table top 19 will be unable to move under the positioning of the support rod 18 and the support of the first support plate 7, thereby forming a stable desktop. Then the second tenon 36 is inserted into the second mortise groove 34, and the second support plate 12 is slid along the oblique direction through the slide rail 11 and the slideway 10 to contact with the limit block 32, and then supported by the limit block 32 to prevent the slide rail 11 from separating from the slideway 10. Fig.13 , Fig.14 As shown, the second support plate 12 is located below the first support plate 7, and the first support plate 7 is located below the table top 19, supporting the table top 19 to improve the stability of the table top 19, and the first support plate 7 and the second support plate 12 will not be exposed and protrude to affect the use.

[0059] The slide rail 11 is a T-shaped structure, so that the second support plate 12 and the first support plate 7 can slide obliquely along the inclined surface and cannot be directly separated. The block 16 is an L-shaped structure, so that the block 16 can only rotate in the transfer rail 14 and cannot be separated.

[0060] The support block 37 supports the table top 19 to improve the stability of the table top 19 when in use;

[0061] The upper surfaces of the second support plate 12, the main board 1, the table top 19, the first support plate 7 and the second support plate 12 are all on the same horizontal plane, so that the coffee table surface is flat without protrusions or depressions that affect actual use.

[0062] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes (such as setting the table top 19 to a triangle, rectangle, etc.), modifications, additions or replacements made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
