Embodiment 1
[0049] Such as Figure 1 to Figure 14 As shown, a plastic-steel window frame right-angle screw connection structure, including a first plastic-steel profile 11 and a second plastic-steel profile 2 perpendicular to each other and a connector, one end of the first plastic-steel profile 11 is provided with a gap 1101, the second plastic-steel profile 2 One end of one end is set as a vertically connected convex body 201 matched with the notch of the first plastic-steel profile, and pre-drilled holes are respectively arranged on the first plastic-steel profile 11 and the second plastic-steel profile 2; Steel insert 6, the outer sleeve is set as a cuboid with an opening at the top, the opening extends downwards to form a cavity 501, a through hole is arranged at the center of the bottom of the cavity, and the bottom of the outer sleeve is also provided with a base 5 extending around. The opposite sides of the cavity 501 are provided with installation through holes; the insert 7 is s...
Embodiment 2
[0051] Such as Figure 10 and Figure 11 As shown, a right-angle screw connection structure of plastic-steel window frame, the structure is as described in embodiment 1, the difference is that the lower surface of the outer sleeve base is provided with a cylindrical protrusion 4 vertical to the lower surface of the base, and the cavity The through hole at the bottom passes through the protrusion, and the cylindrical protrusion corresponds to the pre-drilled hole on the second plastic-steel profile. The pre-drilled hole embedded in the second plastic-steel profile enables the cylindrical protrusion to fit closely with the pre-drilled hole, increasing the firmness of the connection between the connecting piece and the second plastic-steel profile.
Embodiment 3
[0053] Such as Figure 10 and Figure 11 As shown, a plastic-steel window frame right-angle screw connection structure, the structure is as described in Embodiment 1, the difference is that the lower surface of the outer sleeve base 5 is provided with an upwardly recessed card slot 503 . When the outer sleeve is matched with the second plastic-steel profile, the card slot can be snapped onto the second plastic-steel profile, which increases the firmness of the entire connecting piece when matched with the second plastic-steel profile.
