Problems solved by technology

[0002] Hinges are mainly installed on windows. At present, ordinary hinges on the market are generally installed on window types that open inward or outward on the side of the window. Basically, the commonly used hinges extend from the fan to the frame. That is to say, when the rubber strip is compressed and sealed, the hinge must be sandwiched in the middle, and some even have to cut off a section of the rubber strip, which affects the sealing performance, affects the sealing performance of the window and the energy-saving effect, and reduces the thermal insulation, heat insulation and sound insulation of the window; There have been hidden hinges on the market, but due to the complex structure and many parts, when the hinge is stretched and opened, the cutting edge of the sash and window frame will often appear stuck, which is not conducive to the hinge rotating at the maximum angle and unfolding. It is difficult to achieve a tight fit on the sides of the rear sash and window frame
