M260946 V. Creation Instructions (2)

The driven protrusion 503 of the lever 500 moves from the recessed portion of the rotating cam lever 400 to the top portion b, and is then locked by the top portion b again entering the recessed portion 403 of the cam lever 400. However, during the automatic opening and closing process of the cover relative to the main body, the cam lever 400 and the driven protrusion 503 have a sliding friction structure with each other. Due to the large sliding friction resistance, the cam lever 400 and the driven protrusion are easily caused. The mutual wear of the parts 503 reduces the service life of the hinge structure. In addition, the lever 500 of the hinge structure is integrated with the hinge member 501, which complicates the structure of the component and is not convenient for It processing. Once the convex portion 503 is worn, it needs to be replaced as a whole, thereby causing unnecessary waste. In view of this, it is necessary to provide a hinge structure with less cam wear during the automatic opening and closing process and easy manufacture and replacement.

Creation instructions (4) The second cam piece 3 is made of plastic material by injection molding, and is generally a hollow cylindrical shape. # Including a central hole 31, two cam surfaces 32, two cut surfaces 33, and a valley 34. Among them, the two cam surfaces 22 successively constitute a |, a top portion 322, and an inclined surface 323 'After the first cam member ^ the second cam member 3 is assembled and assembled', the aforementioned cylinder 2 may be on the two cam surfaces 32 and the two tangent surfaces 33 to each other. Parallel, it can cooperate with the inner wall of the casing 5, and the recesses pass through the two cutting planes 33 vertically. The elastic element 4 is usually a helical compression spring, which can be placed in the casing 5 with one end thereof abutting against the end surface of the second cam member 3 and the other end against a partially closed end (not shown) of the casing 5. The outer shell 5 is generally a hollow cylinder made of a metal material. The outer shell 5 includes a closed end with 4 wounds and an open end (not labeled), and also has two cutting planes 51 for fixing. The outer contour of the cam member 3 is closely matched with β °, and a shaft hole 5 2 is opened in the center of the end surface of the partially closed end, so that the longitudinal shaft 6 can pass therethrough during assembly. The longitudinal axis 6 is a solid cylinder made of metal material, usually 45 # steel.
