[0036] The specific structure of the frame using the clamping structure is as follows:

[0037] Example One:

[0038] The frame includes four connecting columns 2 arranged at the corners and two layers of enclosures arranged at intervals, the lower one is a first enclosure 11 and the upper one is a second enclosure 12, the connecting column 2 is a first upright 13, the first upright 13 supports the first enclosure 11 and the second enclosure 12, the upper surface of the second enclosure 12 is provided with a suction cup 14, and a panel 15 is arranged on the suction cup 14, which is used to form a tabletop, a tea table top or a board surface for placing articles.

[0039] The connecting strip 1 is bent at the first notch 7 and connected end to end to form a horizontally arranged fence, and four clamping assemblies 5 on the connecting strip 1 clamp four first columns 13 respectively. The end-to-end connection is as follows: The two ends of the connecting strip 1 respectively extend along the length direction of the connecting strip 1 and have mounting segments 16, the mounting segments 16 and the end faces of the connecting strip 1 form mounting positions for the other mounting segments 16 to extend into, and the two mounting segments 16 are fixedly connected by a first fastener 35. In this way, the connecting strip 1 clamps four first columns 13 in a circle, and then the locking is completed by one or two first fasteners 35, thereby improving the installation efficiency.

[0040] The mounting groove 3 on the first column 13 corresponding to the installation of the second fence 12 is divided into a first mounting groove 18 and a second mounting groove 19, the second mounting groove 19 is arranged above the first mounting groove 18 and at the top of the first column 13, and the second mounting groove 19 is a stepped structure.

[0041] In the embodiment, the first column 13 is a square tube, the second notch 9 includes two right-angle walls 20 intersecting at right angles, and a chamfer 21 is arranged between the two right-angle walls 20, the chamfer 21 extends into the mounting groove 3 of the side wall of the first column 13 after the two second notches 9 are closed, and the right-angle walls 20 are attached to the outer side wall of the square tube.

[0042] Embodiment two:

[0043] As shown in Figures 8-11 , the difference between embodiment two and embodiment one is that the first column 13 is a circular tube, and the structure of the second notch 9 is correspondingly adapted, the second notch 9 includes a first arc-shaped wall 22, a second arc-shaped wall 23 and a limiting wall 24 connecting the first arc-shaped wall 22 and the second arc-shaped wall 23, the sizes of the first arc-shaped wall 22 and the second arc-shaped wall 23 match the size of the outer side wall of the circular tube, and the limiting wall 24 extends into the mounting groove 3 after the two second notches 9 are closed, and the first arc-shaped wall 22 and the second arc-shaped wall 23 are attached to the outer side wall of the circular tube.

[0044] Embodiment three:

[0045] As shown in Figure 13 , the difference between embodiment three and embodiment one is that the whole frame is rectangular and relatively long, therefore, the fence includes two connecting strips 1 connected end to end, and a second column 25 is further arranged between the two first columns 13, a second mounting hole 26 for mounting the second column 25 is arranged on the connecting strip 1, and the second column 25 is fixed with the connecting strip 1 by a second fastener 27.

[0046] Embodiment four:

[0047] As shown in Figure 13、 14 As shown, the difference between the fourth embodiment and the first embodiment is that a third frame is added on the basis of the first embodiment, specifically, a third frame 28 is added above the second frame 12, the projection area of the third frame 28 on the horizontal plane is smaller than the projection area of the second frame 12 on the horizontal plane. Four third columns 29 are arranged between the second frame 12 and the third frame 28.

[0048] The connecting strip 1 in the second frame 12 is a second connecting strip 30, in the second connecting strip 30, the end face of the connecting section 4 close to the first notch 7 is provided with two second notches 9, the connecting plate 6 is inwardly bent and the two connecting sections 4 are inwardly close to each other, then the two second notches 9 on one connecting section 4 and the two second notches 9 on the other connecting section 4 are close to each other and form two first mounting holes 10, the first column 13 is mounted in the first mounting hole 10 on the outside, the third column 29 is mounted in the first mounting hole 10 on the inside, and the third mounting groove 3 is provided on the side wall of the third column 29 for the edge of the second notch 9 to extend into.

[0049] The third frame 28 is connected with the upper part of the third column 29, for reference, the connection mode of the second frame 12 and the first column 13. The third frame 28 can be mounted with a panel 15 to form a tabletop, a tea table top or a plate surface for placing articles. The third frame 28 is smaller relative to the first frame 11 and the second frame 12, which can increase the level of design.

[0050] In summary, by using the clamping structure and the frame of the present application, the connecting strip 1, the first column 13 and other pipes can be pre-processed in the production workshop, then transported to the installation site for installation, which has lower transportation cost compared with finished product transportation, and only needs to bend the connecting strip 1 and surround a circle to clamp and fix the four first columns 13, then one or two first fasteners can be used to complete the locking, which improves the installation efficiency and significantly reduces the cost compared with the welding mode.

[0051] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes, combinations and changes.
