[0030] A composite profile according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 A composite profile according to an embodiment of the utility model includes an inner profile 100 , an outer profile 120 and a connecting assembly 140 .

[0032] As for the inner profile 100 , the outer side of the inner profile 100 has a first connection portion 110 .

[0033] The outer profile 120 is disposed on the outer side of the inner profile 100 . The outer profile 120 has a first connecting groove 130 . The first connecting portion 110 is embedded in the first connecting groove 130 .

[0034] In this embodiment, an inner profile 100 and an outer profile 120 are provided. The outer side of the inner profile 100 has a first connecting portion 110. The outer profile 120 is provided on the outer side of the inner profile 100. The outer profile 120 has a first connecting groove 130. The first connecting portion 110 is embedded in the first connecting groove 130, thereby facilitating the installation and positioning of the outer profile 120 and the inner profile 100.

[0035] In some specific embodiments, the outer profile 120 includes a first profile body 230 and a second profile body 240, and the first profile body 230 and the second profile body 240 are respectively arranged on opposite sides of the inner profile 100, and the first profile body 230 and the second profile body 240 are both provided with the first connecting groove 130, and the first connecting portion 110 is provided on both directional sides of the inner profile 100, and one first connecting portion 110 is correspondingly connected to one first connecting groove 130, so that the outer profile 120 can cover the opposite sides of the inner profile 100, thereby facilitating the outer profile 120 to protect the inner profile 100.

[0036] In some specific embodiments, the inner profile 100 is configured as a glass fiber reinforced polyurethane profile, and the outer profile 120 is configured as a metal profile.

[0037] It can be understood that the inner profile 100 is set as a glass fiber reinforced polyurethane profile, so that the composite profile has the advantages of high strength, high modulus, corrosion resistance, wear resistance, etc. At the same time, the outer profile 120 is set as a metal profile, so that the metal profile can be used as a decorative material for the glass fiber reinforced polyurethane profile, with a variety of decorative types and color options.

[0038] Furthermore, the outer profile 120 is configured as an aluminum profile, thereby facilitating material acquisition and production.

[0039] For the connecting component 140, the connecting component 140 is located between the first connecting part 110 and the first connecting groove 130, and the connecting component 140 includes a first key groove 150, a second key groove 160 and a glue body 170. The first key groove 150 is arranged on the outer wall of the first connecting part 110, and the second key groove 160 is arranged on the inner wall of the first connecting groove 130. The first key groove 150 and the second key groove 160 cooperate to form a key pit groove 180, and the key pit groove 180 cooperates with the glue body 170 to be clamped and limited.

[0040] It can be understood that, after injecting glue into the key groove 180, the glue forms a glue body 170 after curing, so that the glue body 170 forms a solid key strip in the key groove 180. On the one hand, the glue body 170 has adhesive force, which can adhere and fix the outer profile 120 and the inner profile 100. On the other hand, the cured glue body 170 is solid, and the glue body 170 and the key groove 180 cooperate to form a limiting form of the key strip and the key groove, so that the glue body 170 and the key groove 180 cooperate to limit the first connection part 110 from being separated from the first connection groove 130. Therefore, the glue body 170 can still maintain the limiting effect on the first connection part 110 and the first connection groove 130 after the adhesive force fails or weakens, so that the outer profile 120 and the inner profile 100 are not easy to separate or fall off, and the connection and composite stability of the outer profile 120 and the inner profile 100 are effectively enhanced.

[0041] Reference Figure 2 and Figure 3 In some specific embodiments, a recess 190 is provided on the side wall of the bottom of the second key groove 160, so that when the glue is solidified in the second key groove 160 to form a glue body 170, the glue body 170 can form a convex portion at the corresponding position of the concave portion 190, so that the convex portion and the concave portion 190 can cooperate to limit, thereby preventing the glue body 170 from detaching from the second key groove 160, making the glue body 170 more firmly in the second key groove 160.

[0042] In some specific embodiments, the second keyway 160 extends obliquely in the depth direction, so that the groove opening and the groove bottom of the second keyway 160 are offset, that is, the groove opening and the groove bottom are not in the same straight line, and thus, the second keyway 160 can limit the glue body 170 to prevent the glue body 170 from detaching from the second keyway 160, making the glue body 170 more firmly in the second keyway 160.

[0043] Furthermore, the groove depth direction of the second key groove 160 extends obliquely toward the groove opening of the first connecting groove 130 .

[0044] It can be understood that when injecting glue, the glue is first injected into the first connecting groove 130, and then the first connecting part 110 is embedded in the first connecting groove 130, so that the first connecting part 110 squeezes the glue in the first connecting groove 130, and the glue in the first connecting groove 130 is squeezed by the first connecting part 110 to flow toward the notch of the first connecting groove 130, and the glue can enter the first key groove 150 and the second key groove 160 when passing through the first key groove 150 and the second key groove 160 during the flow process, and the groove depth direction of the second key groove 160 is tilted and extended toward the notch of the first connecting groove 130, thereby making the groove depth direction of the second key groove 160 tilt and extend along the flow direction of the glue, thereby making it easier for the glue to fill the second key groove 160.

[0045] In some specific embodiments, a plurality of keyway grooves 180 are provided, and the plurality of keyway grooves 180 are sequentially arranged along the groove depth direction of the first connecting groove 130 , thereby further strengthening the connection strength between the outer profile 120 and the inner profile 100 .

[0046] In some specific embodiments, a bonding gap 200 is provided between the outer wall of the first connecting portion 110 and the inner wall of the first connecting groove 130, a portion of the glue body 170 solidifies in the key pit groove 180, and another portion of the glue body 170 solidifies in the bonding gap 200, thereby increasing the bonding area between the glue body 170 and the first connecting portion 110 and the first connecting groove 130, and further increasing the bonding strength of the glue body 170 to the outer profile 120 and the inner profile 100, so that the bonding between the outer profile 120 and the inner profile 100 is more firmly secured.

[0047] Reference Figure 4 In some specific embodiments, the notch of the first connecting groove 130 has an arc-shaped edge 210, and the root of the first connecting portion 110 has an arc-shaped support 220 extending outward, and the arc-shaped support 220 abuts against the arc-shaped edge 210 to support and position, thereby facilitating the positioning between the first connecting portion 110 and the first connecting groove 130, and further facilitating the formation of a bonding gap 200 between the first connecting portion 110 and the first connecting groove 130.

[0048] In some specific embodiments, the glue body 170 is configured as a polyurethane structural glue, so that the glue body 170 can withstand a large dynamic load and a static load and can be used for a long time.
