DETAILED DESCRIPTION

[0027] Example 1

[0028] See Figures 1 to 6The round tube folding table of this embodiment includes an upper connecting frame 1, a lower connecting frame 2, and a folding unit 3 that can be bent toward each other and is arranged between the upper connecting frame 1 and the lower connecting frame 2. The folding unit 3 is two groups of round tubes 31 that are arranged opposite to each other up and down. A connecting member 4 is provided between the round tubes 31 that are arranged opposite to each other up and down. The connecting member 4 includes a connecting head 41, a spring 43 and a connecting piece 42. The two connecting heads 41 are respectively inserted into the opposite ends of the upper and lower round tubes 31. The opposite ends of the two connecting heads 41 are provided with a hinged portion 412 and a spring seat 411. The two ends of the spring 43 are respectively located in the opposite spring seats 411 of the two connecting heads 41, and the two ends of the connecting piece 42 are respectively hinged to the hinged portions 412 of the two connecting heads 41. The hinged part is provided with a connecting hole 413, and two through holes 421 matching the connecting hole 413 are respectively provided at both ends of the connecting piece 42. A pin is provided in the connecting hole 413 and the through hole 421, and the pin passes through one of the connecting pieces 42, the hinged part 412 and the other connecting piece 42 in sequence. The opposite ends of the two connectors 41 are also provided with a protrusion 414 and a groove 415 that are plugged and matched with each other. Each group of round tubes 31 has two, and the ends of the two round tubes 31 away from the connector 41 are provided with a fixed tube 311 connecting the two round tubes 31. The upper connecting frame 1 and the lower connecting frame 2 are provided with fixed through holes opposite to each other, and the two ends of the fixed tube 311 match the fixed through holes. The two ends of the fixed tube 311 are hinged to the upper connecting frame 1 or the lower connecting frame 2 through the limit pin 5 passing through the upper connecting frame 1 or the lower connecting frame 2. The upper connecting frame 1 is fixedly connected with a top plate 6, and the lower connecting frame 2 is fixedly connected with a bottom plate 7. The top plate 6 and the bottom plate 7 are blister panels. The diameter of the round tube is 30 mm. There are two springs 43 between a pair of connectors 41. A light strip is arranged inside the round tube 31.

[0029] When the circular tube folding table is folded, the ends of the two circular tubes 31 opposite to each other gradually move toward the adjacent circular tube 31. At this time, each spring 43 provided between each upper and lower spring seats 411 begins to bend, and the two adjacent circular tubes 31 on the left and right are cross-arranged; when the folding is completed, the two circular tubes 31 opposite to each other are transversely arranged to fit each other, are clamped between the top plate 6 and the bottom plate 7, and fit each other with the top plate or the bottom plate respectively.
