新型铰链10的上合页100、转动轴200和下合页400相互连接，其中上合页100与转动轴200转动连接。设置在上合页100上的限位销300可滑动地设置限位槽210内，如此通过限位销300和限位槽210的配合即可实现新型铰链10的限位功能，不需要再设置风钩等限位结构。这样的新型铰链10结构简单、自身具有限位功能，无需附加其他限位结构，且安装方便、外观美观，具有显著的经济效益。Theupper hinge 100 , therotating shaft 200 and thelower hinge 400 of the novel hinge 10 are connected to each other, wherein theupper hinge 100 is rotatably connected with therotating shaft 200 . Thelimit pin 300 provided on theupper hinge 100 is slidably disposed in thelimit groove 210, so that the limit function of the new hinge 10 can be realized through the cooperation of thelimit pin 300 and thelimit groove 210, and no further setting is required. Limiting structures such as air hooks. Such a novel hinge 10 has a simple structure, has a limiting function itself, does not need to add other limiting structures, is easy to install, has a beautiful appearance, and has significant economic benefits.

以上所述，仅为本实用新型的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本实用新型的保护范围之内。因此，本实用新型的保护范围应以所述权利要求的保护范围为准。The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field of the present invention can easily think of changes within the technical scope disclosed by the present invention. Or replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
