The toothed angle code 200 is an L-shaped structure, including a first insertion arm 220 and a second insertion arm 230. Angle code teeth 210 are respectively arranged on the side walls of the first insertion arm 220 and the second insertion arm 230.

[0045] Two adjacent frame profiles 100 are connected by a toothed angle code 200. Specifically, the first insertion arm 220 of the toothed angle code 200 is inserted into the plug-in cavity 110 of one of the frame profiles 100, and the second insertion arm 230 of the toothed angle code 200 is inserted into the plug-in cavity 110 of the other frame profile 100.

Figure 4 The figure shows a cross-sectional view of two adjacent frame profiles 100 after being connected. Figure 5 A schematic diagram of a frame profile 100 is shown.

[0047] In the prior art, after the corner code is inserted into the plug-in cavity 110 of the frame profile 100, in order to improve the connection stability between the corner code and the frame profile 100, one method is to drill holes in the side walls of the plug-in cavity 110 to install fasteners, and drilling holes will damage the structural strength of the frame profile 100; another method is to fix the corner code on the inner wall of the plug-in cavity 110 by gluing, and the gluing method will produce new pollution.

[0048] In order to solve the above technical problems, the present embodiment improves the connection structure between the plug-in cavity 110 and the toothed angle code 200. Specifically, at least one protruding rib 120 is provided on the inner wall of at least one side of the plug-in cavity 110, and the protruding rib 120 extends along the length direction of the plug-in cavity 110. At least one clamping portion 130 is provided on the protruding rib 120, and the clamping portion 130 is used to clamp with the angle code teeth 210 of the toothed angle code 200, so as to fix the toothed angle code 200 into the plug-in cavity 110.

[0049] In other words, one end of the toothed angle code 200 is inserted into the plug-in cavity 110, and the angle code teeth 210 are correspondingly engaged with the clamping portion 130, thereby fixing the toothed angle code 200 to the frame profile 100, achieving quick connection between the toothed angle code 200 and the frame profile 100, which is convenient for installation.

[0050] The diagonal code teeth 210 are clamped together by the built-in clamping portion 130, and there is no need to drill holes and insert fasteners on the side walls of the frame profile 100 to fix the toothed corner code 200 as in the prior art, thereby avoiding reducing the structural strength of the frame profile 100; or to glue the toothed corner code 200 to the inner wall of the plug-in cavity 110 by gluing, thereby avoiding additional glue pollution.

[0051] The raised ribs 120 are formed by pultrusion of the frame profile 100 , and the raised ribs 120 enhance the structural strength of the frame profile 100 .

[0052] In some embodiments, a plurality of spaced-apart raised ribs 120 are disposed on the inner wall of at least one side of the insertion cavity 110 . The plurality of raised ribs 120 help to further improve the structural strength of the frame profile 100 .

The same angle code tooth 210 of the toothed angle code 200 is clamped with multiple clamping portions 130 at the same height position, which helps to further improve the connection reliability between the toothed angle code 200 and the frame profile 100.

[0058] In some embodiments, the clamping portion 130 is a notch provided on the raised rib 120 for ease of processing and manufacturing. Figure 5 The notch passes through the raised rib 120, so as to facilitate smooth and unobstructed engagement between the angle code tooth 210 and the notch.

[0060] In some embodiments, fiber fabric (not shown) is distributed on at least the inner wall of the plug-in cavity 110 provided with the raised ribs 120.

Correspondingly, a raised rib 120 is provided on the inner wall of one side of the plug-in cavity 110, and a clamping portion 130 is provided on the raised rib 120.

[0068] The serrations 240 help to increase the friction between the toothed corner bracket 200 and the inner wall of the insertion cavity 110 , thereby improving the connection reliability between the toothed corner bracket 200 and the frame profile 100 .

[0069] In some embodiments, reference Figure 8, angle code teeth 210 are arranged on two opposite side walls of the toothed angle code 200.
