[0029] See also Figure 1 In one embodiment, a plastic-steel composite profile 100 includes a plastic-steel body 110, a metal cover 130, and an adhesive layer 150. The plastic-steel composite profile 100 is used to produce plastic-steel doors and windows. In the illustrated embodiment, the plastic-steel composite profile 100 is a center-support plastic-steel composite profile.

[0030] See also Figure 2 The plastic-steel body 110 has a covering surface 111 , a first abutting surface 112 , a second abutting surface 113 , a first clamping surface 114 , a second clamping surface 115 , a heat-insulating cavity 116 and a receiving cavity 117 .

[0031] The covering surface 111 is one of the surfaces of the plastic-steel body 110. When the plastic-steel body 110 is made into a plastic-steel door or window, the covering surface 111 is the outer surface of the plastic-steel body 110. In one embodiment, the covering surface 111 is a plane.

[0032] The first abutting surface 112 and the second abutting surface 113 are used to abut the metal cover 130, which helps to stabilize the metal cover 130. The first abutting surface 112 and the second abutting surface 113 are located on either side of the plastic-steel body 110, and the first abutting surface 112 and the second abutting surface 113 are arranged opposite each other. The covering surface 111 is located between the first abutting surface 112 and the second abutting surface 113 and is connected to the first abutting surface 112 and the second abutting surface 113.

[0033] In one embodiment, at least one of the first abutting surface 112 and the second abutting surface 113 is an inclined surface to serve as a guide when assembling the metal cover 200. In the illustrated embodiment, both the first abutting surface 112 and the second abutting surface 113 are inclined surfaces.

[0034] The first clamping surface 114 and the second clamping surface 115 are used to clamp with the metal cover 130 to fix the metal cover 130 on the plastic-steel body 110. The first clamping surface 114 and the second clamping surface 115 are located on opposite sides of the plastic-steel body 110. In the illustrated embodiment, the first clamping surface 114 and the second clamping surface 115 are both parallel to the covering surface 111. Furthermore, the first clamping surface 114 is located on the side of the plastic-steel body 110 close to the first abutting surface 112. Furthermore, the first clamping surface 114 is connected to the first abutting surface 112. The second clamping surface 115 is located on the side of the plastic-steel body 110 close to the second abutting surface 113. Further, the second clamping surface 115 is connected to the second abutting surface 113.

[0035] The insulation cavity 116 is used for thermal insulation. As a cavity filled with air, the insulation cavity 116 provides excellent thermal insulation. Of course, the insulation cavity 116 also provides sound insulation. In one embodiment, there is at least one insulation cavity 116. If there are multiple insulation cavities 116, they are spaced apart to provide better thermal and sound insulation.

[0036] The accommodating chamber 117 is used to accommodate the steel lining. Of course, the accommodating chamber 117 also has good heat insulation and sound insulation effects. In the illustrated embodiment, the accommodating chamber 117 is provided with heat insulation chambers 116 on both sides.

[0037] Please also refer to Figure 3 The metal cover 130 is placed on the plastic-steel body 110 and is clamped to the plastic-steel body 110, forming a buffer cavity 101 between the metal cover 130 and the plastic-steel body 110. The buffer cavity 101 has a dimension of at least 2 mm perpendicular to the cover surface 111. This dimension allows for more adhesive layer 150 to be accommodated, ensuring a stable connection between the metal cover 130 and the plastic-steel body 110.

[0038] In one embodiment, the metal cover 130 is an aluminum alloy cover. The aluminum alloy cover ensures the strength of the plastic-steel composite profile 100 while maintaining its light weight, facilitating the transportation and installation of the plastic-steel door and window. Specifically, the metal cover 130 includes a main plate 131, a first connecting portion 132, and a second connecting portion 133.

[0039] The main board 131 covers the cover surface 111. In one embodiment, the main board 131 covers at least the surface of the cover surface 111. In the illustrated embodiment, the main board 131 completely covers the cover surface 111, preventing the cover surface 111 from cracking due to prolonged sunlight exposure.

[0040] In one embodiment, the thickness of the main plate 131 is 0.2 mm to 3.0 mm. This thickness ensures the strength of the plastic-steel composite profile 100 while ensuring its light weight, facilitating the transportation and installation of plastic-steel doors and windows. Preferably, the thickness of the main plate 131 is 0.5 mm to 1.2 mm.

[0041] The first connecting portion 132 and the second connecting portion 133 are fixedly disposed at two ends of the main board 131 . The first connecting portion 132 and the second connecting portion 133 are respectively engaged with the plastic-steel body 110 to fix the metal cover 130 to the plastic-steel body 110 .

[0042] Furthermore, the first connecting portion 132 and the second connecting portion 133 are respectively bent and extended from both ends of the main plate 131 toward one side of the main plate 131 close to the plastic-steel body 110, and then bent and extended in a direction close to each other to be clamped with the plastic-steel body 110 to fix the metal cover to the plastic-steel body 110.

[0043] Specifically, the first connecting portion 132 includes a first resisting member 1321 and a first clamping member 1322 connected to the first resisting member 1321. The first resisting member 1321 is bent and extended from one end of the main plate 131 to the side of the main plate 131 close to the plastic steel body 110. The first clamping member 1322 is bent and extended from the end of the first resisting member 1321 away from the main plate 131 to the side close to the second connecting portion 133. The second connecting portion 133 includes a first resisting member 1331 and a first clamping member 1322 connected to the first resisting member 1321. The second clamping member 1332 is connected to the holding member 1331, and the first holding member 1331 is bent and extended from the other end of the main plate 131 to the side of the main plate 131 close to the plastic-steel body 110. The second clamping member 1332 is bent and extended from the end of the first holding member 1331 away from the main plate 131 to the side close to the first connecting portion 132. The first clamping member 1322 and the second clamping member 1332 are both clamped with the plastic-steel body 110 to fix the metal cover 130 to the plastic-steel body 110.

[0044] In the illustrated embodiment, the extending direction of the first clamping member 1322 and the extending direction of the second clamping member 1332 are both parallel to the covering surface 111 .

[0045] The first abutting member 1321 abuts the first abutting surface 112, while the first abutting member 1331 abuts the second abutting surface 113. The first clamping member 1322 clamps the first clamping surface 114, while the second clamping member 1332 clamps the second clamping surface 115. A relatively closed buffer chamber 101 is formed between the main plate 131 and the plastic-steel body 110, providing the plastic-steel composite profile 100 with improved thermal and sound insulation.

[0046] In one embodiment, a sunscreen layer (not shown) is provided on the surface of the metal cover 130 away from the plastic-steel body 110. The sunscreen layer can prevent the surface temperature of the metal cover 130 from being too high, thereby affecting the plastic-steel body 110 and reducing the aging probability of the plastic-steel body 110.

[0047] The adhesive layer 150 is disposed in the buffer cavity 101 and contacts the plastic-steel body 110 and the metal cover 130. The adhesive layer 150 can bond the plastic-steel body 110 and the metal cover 130 to prevent the metal cover 130 from falling off, thereby making the plastic-steel composite profile 100 more stable and reliable.

[0048] Furthermore, the adhesive layer 150 contacts the covering surface 111, and the contact area between the adhesive layer 150 and the covering surface 111 is more than 50% of the area of ​​the covering surface 111, so that the adhesive layer 150 and the plastic-steel body 110 have sufficient contact area, thereby generating sufficient bonding force to ensure that the metal cover 130 will not fall off.

[0049] In one embodiment, the adhesive layer 150 is a foaming agent layer. This not only allows the metal cover 130 and the plastic-steel body 110 to be bonded and fixed, but also provides cushioning, heat insulation, sound insulation, and sun protection. Specifically, the adhesive 150 is a polyurethane foaming agent layer or a resin foaming agent layer.

[0050] Please also refer to Figure 5 In one embodiment, the plastic-steel composite profile 100 further includes a support member 170 disposed within the buffer cavity 101. One end of the support member 170 is secured to the metal cover 130, while the other end penetrates the adhesive layer 150 and contacts the plastic-steel body 110. This arrangement provides support for the metal cover 130, further strengthening the connection between the metal cover 130 and the plastic-steel body 110. Specifically, one end of the support member 170 is secured to the main plate 131, while the other end contacts the cover surface 111.

[0051] Furthermore, the surface of the support member 170 proximal to the plastic-steel body 110 is flat, and the support member 170 extends along the length of the plastic-steel body 110. This ensures a more balanced support force between the metal cover 130 and the plastic-steel body 110, and enhances the overall structural stability. Specifically, the support member 170 is made of a thermoplastic resin, which is less susceptible to aging and has a longer service life. More specifically, the support member 170 is made of nylon, such as PA66.

[0052] Please also refer to Figure 6 In one embodiment, there are multiple support members 170, and the multiple support members 170 are spaced apart and arranged on a side of the mainboard 131 close to the cover surface 111. The multiple support members 170 can make the metal cover 130 more stable.

[0053] Please also refer to Figure 7 In one embodiment, a first fixing member 134 and a second fixing member 135 are spaced apart on a side of the mainboard 131 near the cover surface 111. A fixing groove 136 is formed between the first fixing member 134 and the second fixing member 135. A support member 170 is partially disposed in the fixing groove 136 and fixedly connected to the groove wall of the fixing groove 136. In one embodiment, the support member 170 is engaged or interference-engaged with the groove wall of the fixing groove 136. In another embodiment, the support member 170 is bonded to the fixing groove 136.

[0054] A plastic-steel door and window comprises the above-mentioned plastic-steel composite profile 100. The plastic-steel composite profile 100 is made into a plastic-steel door and window through cutting, welding and assembly.

[0055] The above-mentioned plastic-steel composite profile 100 has at least the following advantages:

[0056] The metal cover 130 of the plastic-steel composite profile 100 is engaged with the plastic-steel body 110, and a buffer cavity 101 is formed between the metal cover 130 and the plastic-steel body 110. The adhesive layer 150 is disposed in the buffer cavity 101 and contacts the plastic-steel body 110 and the metal cover 130, respectively, to bond the plastic-steel body 110 and the metal cover 130. The engagement of the metal cover 130 with the plastic-steel body 110 and the bonding of the plastic-steel body 110 and the metal cover 130 prevents the metal cover from falling off, thereby providing the plastic-steel composite profile 100 with better stability and reliability.

[0057] Please also refer to Figures 8-10 The structure of the plastic-steel composite profile 200 of one embodiment is substantially the same as that of the plastic-steel composite profile 100, except that:

[0058] In the illustrated embodiment, the plastic-steel composite profile 200 is a frame plastic-steel composite profile.

[0059] In the illustrated embodiment, the first abutting surface 212 is an inclined surface, and the second abutting surface 213 is perpendicular to the covering surface 211 .

[0060] In the illustrated embodiment, the first engaging surface 214 is parallel to the covering surface 211 , and the second engaging surface 115 is an inclined surface.

[0061] In the illustrated embodiment, the extending direction of the first clamping member 2332 is parallel to the covering surface 111 , and the extending direction of the second clamping member 2342 intersects with the covering surface 211 .

[0062] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments merely illustrate several implementations of the present invention.
