[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Embodiment 1:

[0031] Figures 1 to 3 The first embodiment of the square tube frame of the horizontal tube rear installation type of the present invention is shown, comprising a horizontal square tube 1, a vertical square tube 2, a connector 3, a first locking member 4 and a second locking member 5. The connector 3 is fastened to the outer wall of the vertical square tube 2 through the first locking member 4, the horizontal square tube 1 is plugged with the connector 3 along its own radial direction, and the horizontal square tube 1 is fastened to the connector 3 through the second locking member 5. During installation, all the vertical square tubes 2 are installed first, and then the connector 3 is fastened to the outer wall of the vertical tube 2 through the first locking member 4, and then the horizontal square tube 1 is plugged with the connector 3 along its own radial direction, and finally the horizontal square tube 1 is fastened to the connector 3 by the second locking member 5. Compared with the traditional structure, the square tube frame can install all the vertical square tubes 2 first and then install the horizontal square tube 1, so that the horizontal square tube 1 can be installed afterward, and the on-site installation is flexible and convenient, saving time and labor, reducing the construction difficulty and improving the construction efficiency.

[0032] In this embodiment, a side wall of the horizontal square tube 1 is provided with an escape socket 11 for escaping the connector 3. In this structure, the escape socket 11 realizes the escape effect when the horizontal square tube 1 is plugged in, and realizes the plug-in cooperation with the connector 3, and the structure is simple and reliable.

[0033] In this embodiment, the connecting member 3 includes a first connecting plate 31, and plug-in plates 32 are bent at both ends of the first connecting plate 31. A second connecting plate 33 is also bent at one side of the first connecting plate 31. The first connecting plate 31 is fastened to the outer wall of the vertical tube 2 through the first locking member 4, and the avoidance socket 11 of the horizontal tube 1 is plugged with the two plug-in plates 32. The second connecting plate 33 is fastened to the horizontal tube 1 through the second locking member 5. In this structure, the first connecting plate 31 is connected to the vertical tube 2 through the first locking member 4, the second connecting plate 33 is connected to the horizontal tube 1 through the second locking member 5, and the two plug-in plates 32 are plugged with the horizontal tube 1, so that the horizontal tube 1 is installed later. The first locking member 4 and the second locking member 5 are both set as bolts.

[0034] In this embodiment, a groove 12 is provided on the horizontal square tube 1, and the second connecting plate 33 is fastened to the bottom wall of the groove 12 through the second locking member 5. In this structure, the arrangement of the groove 12 enables the second connecting plate 33 and the second locking member 5 to be hidden in the groove 12, making the appearance more beautiful and durable.

[0035] In this embodiment, the avoidance socket 11 is provided at the bottom wall edge of the groove 12. This arrangement enables the entire connector 3 to be sunk in the horizontal square tube 1, further improving the external visual effect.

[0036] Embodiment 2:

[0037] Figures 4 to 6 The second embodiment of the square tube frame of the horizontal tube rear-mounted type of the present invention is shown, which is basically the same as the embodiment 1, except that: in this embodiment, the avoidance socket 11 is provided at the edge of the tube wall on both sides of the groove 12. This arrangement allows the tube wall of the horizontal square tube 1 below the avoidance socket 11 to form mutual support with the plug-in board 32, thereby improving the strength.

[0038] Embodiment 3:

[0039] Figures 7 to 10 The third embodiment of the square tube frame of the horizontal tube rear-mounted type of the present invention is shown. The square tube frame is basically the same as the embodiment 1, and the difference is only that: in this embodiment, the connecting member 3 includes a first connecting plate 31, one end of the first connecting plate 31 is bent with a folding plate 34, and both ends of the folding plate 34 are folded with plug-in plates 32. The first connecting plate 31 is fastened to the outer wall of the vertical square tube 2 through the first locking member 4, and the avoidance socket 11 of the horizontal square tube 1 is plugged with two plug-in plates 32, one of which is fastened to the horizontal square tube 1 through the second locking member 5. In this structure, the first connecting plate 31 is connected to the vertical square tube 2 through the first locking member 4, one of which is connected to the horizontal square tube 1 through the second locking member 5, and the two plug-in plates 32 are plugged with the horizontal square tube 1, so that the horizontal square tube 1 is rear-mounted.

[0040] In this embodiment, a groove 12 is provided on the horizontal square tube 1, and the avoidance socket 11 is provided at the edge of the tube wall on both sides of the groove 12, and one of the plug-in plates 32 is fastened to the bottom wall of the horizontal square tube 1 through the second locking member 5. The avoidance socket 11 is provided at the edge of the tube wall on both sides of the groove 12. This arrangement enables the tube wall of the horizontal square tube 1 below the avoidance socket 11 and the plug-in plate 32 to form mutual support, thereby improving the strength. The second locking member 5 is fastened to the bottom wall of the horizontal square tube 1, forming a structure equivalent to surrounding the horizontal square tube 1, and its structure is simple and reliable.

[0041] In this embodiment, a gap is left between the first connecting plate 31 and the two plug-in plates 32. The gap allows the tube wall of the horizontal square tube 1 below the avoidance socket 11 to further form support in the gap, and the structure is simple and the design is ingenious.
