New Description: [New Technology Field] This creation is a kind of hinge device. It refers to a hinge that is placed between the cover of the clamshell device and the base to enable the upper cover to open or close or rotate relative to the base. [Prior Art] A general electronic cover device (such as a notebook computer, a mobile phone, etc.) has an upper cover and a base, and a hinge is arranged between the upper cover and the base to open or close the upper cover relative to the base, in order to cooperate In a diversified manner, the prior art rotary hinge not only enables the upper cover to open and close relative to the base, but also enables the upper cover to rotate relative to the base, and the components of the prior art hinges are rotated relative to each other. Friction, in the long run, accelerates the wear of the component and reduces the service life of the prior art hub. [New content] In view of the aforementioned shortcomings of the prior art, the present invention improves the prior art to improve the service life of the hinge. In order to achieve the above-mentioned creative purposes, the technical means adopted in the present invention is to design a hinge, which comprises: a central frame having a bottom plate, a first side wing and a second side wing, the two side wings are vertically formed on the bottom plate respectively On both sides, a central perforation is formed through the center of the bottom plate; a metal injection molded reinforcing plate is fixed on the outer side of the bottom plate, and a central protrusion is formed on the side of the reinforcing plate relative to the side of the bottom plate, and the central bump of the reinforcing plate runs through The center of the bottom plate is perforated and extends out of the inner surface of the bottom plate M312699; a first opening and closing shaft group is connected to the first side wing; a second opening and closing shaft sleeve is connected to the second side wing; a rotating shaft group, It is connected to the reinforcing plate.
