The cover 7 is made of plastic injection molding, preferably acrylic material. The second protective cover 7 is snap-connected to the fan connecting plate 6. The fan connecting plate 6 and the frame connecting plate 4 are connected by snap-connection mainly for the convenience of disassembly for later maintenance and other needs. The second protective cover 7 is provided with a shielding portion 300 for shielding the rotating shaft 3 on the side close to the rotating shaft 3. The shielding portion 300 has an arc-shaped cross-section, and the shielding portion 300 is arranged concentrically with the rotating shaft 3. The first protective cover 5 and the second protective cover 7 are an integral injection molding structure with a smooth and simple surface. A composite layer is provided on the outer side of the first protective cover 5 and the second protective cover 7. The composite layer represents a color layer. The color of the color layer can be customized according to the color of the installed door or window to maintain the uniformity with the casement door.

[0021] The utility model discloses a stainless steel concealed hinge, which covers a frame connecting plate 4 and a fan connecting plate 6 respectively through a first protective cover 5 and a second protective cover 7, so as to shield the hinge structure and prevent the hinge and its connecting structure from being exposed. The connecting structure refers to a structure such as a screw and a rotating shaft that connects the hinge and a profile or the hinges to each other. Moreover, the first protective cover 5 completely covers the frame connecting plate 4 and cooperates with the frame profile to achieve the effect of hiding the frame connecting plate 4, and the second protective cover 7 completely covers the fan connecting plate 6 and cooperates with the fan profile to achieve the effect of hiding the fan connecting plate 6.
