Description

Pivot device

Technical field

The utility model is about a kind of pivot device, refers in particular between a kind of screen that is arranged at laptop computer and body and has the pivot devices of level to 360 degree Rotation Design.

Background technique

Laptop computer is concerning people, little by little become a kind of important instrument, therefore its convenience on using also becomes the emphasis of a design, in a kind of laptop computer of prior art, between the screen of laptop computer and body except being pivoted mutually to make the screen can be with respect to the body folding, further be to have the function that horizontally rotates with screen design, can be to make the user by the screen rotation is showed the people of screen to the laptop computer both sides or the back side easily.

Yet, the laptop computer of this type can only allow screen towards a left side or the certain angle of right rotation mostly, can't make it complete around a circle (revolving three-sixth turn), therefore when the user after Rotation screen is finished displaying, 180 degree have been surpassed even rotated, also must need again to go back to screen is reverse, could be with the screen reversion to locating with closed screen, and can't select along former direction, directly screen is gone to behind the corresponding position again with on the screen cover with less angle, in operation, more do not have selectivity; Can just can accomplish with the part of somewhat complex design yet it need cooperate mostly for the design of screen 360 degree rotations, for fabricating cost, really be an adverse factors and also there is the small part laptop computer to have.

The model utility content

Because aforesaid the deficiencies in the prior art point, the utility model design is a kind of to be located between the screen and body of laptop computer, have level to the pivot device that revolves the three-sixth turn design, and it is simple for structure.
