Abstract

The utility model relates to a rotating axle used for prolonging a service life. A pivot device comprises a shell body, a cover part and a metal axle. The side edge of the shell body is provided with one or more than one axle base. The side edge of the cover part is also provided with one or more than one axle base correspondingly matched with the axle base of the shell body and the metal axle is positioned on the axle of the side edge of the cover part. The utility model is characterized in that the axle bases of the shell body and the cover part respectively form D-shaped holes and the metal axle is tightly matched and assembled with a C-shaped pin with an outer diameter appropriated to the inner diameters of the D-shaped holes. The C-shaped pin is arranged into the D-shaped holes and the side wall of the C-shaped pin is provided with an opening edge. The utility model is used for the pivoting end of the combination of the shell body and the cover part.

Description

Pivot device

The utility model relates to-a kind of rotating shaft.

Existing pivot structure is as shown in Figure 5: it is penetrated in the axle bed of housing respectively by two rotating shafts, make the cap can be by rotating shaft with open and close, no matter this rotating shaft hollow or solid, is all made up with axle bed, the axle bed combination soft as rotating shaft and plastic cement etc., harder because of the rotating shaft material, the easy to wear and inwall of axle bed is enlarged, in the course of time, such structure just can't be used, and the life-span is shorter.

The purpose of this utility model provides a kind of pivot device of more durable use.

The purpose of this utility model is achieved in that pivot device, it comprises a housing, cap and metal shaft, the housing lateral margin is provided with one or more axle bed, also be provided with a axle bed in the cap lateral margin to the axle bed corresponding matching of more than one and housing, metal shaft is positioned at wherein, it is characterized in that: the axle bed of housing and cap respectively forms D shape hole, and assembling one external diameter that closely cooperates on the metal shaft is similar to the C shape pin of D shape hole internal diameter, and insert in the D shape hole, and C shape pin sidewall is provided with peristome.

Above-mentioned design, the shaped design of mat C shape pin and the antiwear characteristic of material have reached the effect of the durable use of pivot device.

Further specify again below by accompanying drawing, embodiment.
