When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Refer to the attached Figures 1 to 6 In one embodiment of the present invention, a door frame profile structure includes a profile body 100 having a first platform 11, a second platform 12, and a third platform 13 spaced apart from each other. A first cavity 21 is formed between the first and second platforms 11, 12, and a second cavity 22 is formed between the second and third platforms 12, 13. The first platform 11 defines an installation opening 111 for installing a hinge, the installation opening 111 communicating with the first cavity 21. The rear side of the first cavity 21 protrudes beyond the second cavity 22. The installation opening 111 is typically a waist-shaped groove.

[0028] During application, when the door frame needs to be installed with visible hinges 31 or two-dimensional hidden hinges 32, the visible hinges 31 or two-dimensional hidden hinges 32 can be directly fixed to the first platform 11 by self-drilling screws. When the three-dimensional hidden hinge 33 needs to be installed, the three-dimensional hidden hinge 33 is installed in the first cavity 21 through the installation opening 111, and then the three-dimensional hidden hinge 33 is fixedly connected to the second platform 12 by self-drilling screws.

The decorative insert 42 is preferably a carbon crystal plate, and the profile body 100 is preferably an aluminum profile.

[0031] Furthermore, the front side of the first platform 11 is provided with an extension boss 14 with a trapezoidal cross-section. An extension plate 15 is provided on the left side of the extension boss 14. A clamping groove 16 for mounting a pinch plate 161 is formed between the extension boss 14 and the extension plate 15. The trapezoidal lower base of the extension boss 14 is integrally connected to the first platform 11; the trapezoidal upper base of the extension boss 14 is parallel to the first platform 11 and is located to the right of the first platform 11. The extension boss 14 is preferably a hollow structure, having a fourth cavity within it.

[0032] The rear side of the extension boss 14 is provided with a second mounting groove 141 for mounting the anti-collision and sound insulation strip 50. The first mounting groove 41, the second mounting groove 141, and the buckle groove 221 can be either T-shaped grooves or dovetail grooves. The anti-collision and sound insulation strip 50 is preferably a silicone strip.

[0033] The design focus of the present utility model is that it mainly provides a first cavity and an installation opening on the profile body for installing a three-dimensional hidden hinge, and the first cavity is convexly provided on the second cavity, so that the profile body can adapt to the visible hinges, two-dimensional hinges, and three-dimensional hinges on the market, and has the advantage of better versatility; secondly, a third cavity and reinforcing ribs are provided in the profile body, which takes into account the strength and manufacturing cost of the profile body and improves durability; furthermore, by selecting aluminum profiles, it also has many advantages such as light weight and rust resistance.
