Embodiment

Below in conjunction with the drawings and specific embodiments, embodiment of the present utility model is described in further detail:

The utility model provides a kind of pivot device that reduces abrasion, described pivot device can be installed on notebook computer, DVD audio and video player or the e-dictionary, utilize pivot device of the present utility model that the LCD Display and the body of said apparatus are linked, can drive the upset of LCD Display, LCD Display is raised and locate, make this LCD Display rotary manipulation stably.

Figure 1 and Figure 2 is respectively perspective view of the present utility model and STRUCTURE DECOMPOSITION figure thereof, and as shown in Figure 1, a rotating shaft 10 which is provided with at least one first fixed hole 102, can be fixed on the main frame; One L shaped fixing frame 12, vertically being arranged in the rotating shaft 10 wherein than minor face, and be provided with two positioning grooves 122, another longer sides is then parallel with rotating shaft 10, and is provided with at least one second fixed hole 124, can be fixed on the LCD Display; Certain hyte part 14 is arranged in the rotating shaft 10, and is located between fixing frame 12 and the plural spring washer 16, is provided with two raised lines 142 on this positioning component 14, can be embedded in the positioning groove 122 respectively; Be provided with a locked assembly 18 at rotating shaft 10 ends, this locked assembly can adopt nut, in order to be locked in fixing frame 12, positioning component 14 and spring washer 16 in the rotating shaft and to fit tightly.

Raised line 142 is all with positioning groove 122 and is symmetrical arranged, and when fixing frame 12 rotated in rotating shaft 10, this raised line 142 just slipped in the positioning groove 122 and fixes, and reached the purpose of location, and this positioning component is the two-part location, so LCD Display can be raised 180 degree; In addition, the material of rotating shaft 10 and fixing frame 12 is a tool steel, and a packing ring 20 also can be set between rotating shaft 10 and fixing frame 12, produces with rotating shaft 10 when avoiding fixing frame 12 rotation and rubs.
