Surface pipe corner connection component

[0030] Figure 1 to Figure 6 It shows the first embodiment of the surface pipe corner connection assembly of the present invention, the connection assembly includes a waist-shaped steel core 1 and a decorative shell 2, the decorative shell 2 is provided with insertion holes 21 on both sides, and the waist-shaped steel core 1 runs through the insertion hole 21 and is firmly connected with the decorative shell 2. The waist-shaped steel core 1 and the decorative shell 2 just form a similar arc-shaped corner when used together. Its structure is simple and easy to install, while the waist-shaped steel core 1 and the decorative shell 2 form a movable sleeve cavity 4 for inserting the double-sided tube 3 and can adjust the rotation angle of the double-sided tube 3. The two surface tubes 3 are respectively inserted into the movable sleeve cavity 4 and adjusted. The fastener 5 is fastened to the waist-shaped steel core 1. On the one hand, the movable sleeve 4 enables the two surface tu...

[0038] Figure 7 to Figure 10 It shows the second embodiment of the surface pipe corner connection assembly of the present invention, which is basically the same as the first embodiment, the difference is only that: the end of the socket part 12 is bent with a side plate 122, and the end of the side plate 122 is bent A jacking plate 123 is folded, and the first fastener 5 passes through the first threaded hole 121 and resists the jacking plate 123. When the first fastener 5 is tightened, the jacking plate 123 expands and contacts the surface tube 3. The inner wall is connected by expansion and tightness, which further improves the connection stability between the waist-shaped steel core 1 and the surface pipe 3 .

[0040] Figure 11 Shown is the third embodiment of the surface pipe corner connection assembly of the present invention, which is basically the same as Embodiment 1, the only difference being that the two surface pipes 3 can be rotated between 135° and 5 with the first fastener 5 as the center. Rotate between 180°, that is, realize the angle adjustment range of the two surface pipes 3 by changing the inclination angle of the socket hole 21, which is very convenient to operate and effectively expands the applicable range of the connection assembly.
