Abstract

The utility model relates to an improved hinge structure, in particular to a hinge which enables a hinged object to elevate automatically during opening and closing. An upper shaft lining and a lower shaft lining are assembled through a rotating shaft, and the lower end opening oblique surface of the upper shaft lining is in rotary fit with the upper end opening oblique surface of the lower shaft lining. An upper fixed arm fixedly connected onto the upper shaft lining is fixedly connected onto a door window or a well cover, and a lower fixed arm fixedly connected onto the lower shaft lining is fixedly connected onto a door window frame fixed on a wall body or a well wall. The improved hinge structure is widely applied with more flexibility and practicability. When a vehicle door, a vehicle window or a well cover is opened or closed rationally, the hinged object can be lifted in the axial height of the hinge or be closed through lowering due to the gravity. Thus, the door window or the well cover can be opened or closed smoothly because the lower end of the door window or the undersurface of the well cover can avoid the uneven or non-level surface.

Description

But the hinge of hinged thing folding automatic lifting

Technical field

The improvement of the utility model hinge structure, but the hinge of particularly hinged thing folding automatic lifting.

Background technology

As everyone knows, be used in the hinge on door and window, car door or the well lid now, its structure is simple articulated structure, needs the door and window of rotary opening closing or cloudy well etc. to be hinged on the doorframe and window frame that is fixed on the body of wall door and window or well lid etc.In case the ground surface out-of-flatness of door and window below or out-of-level the time, the soffit that will occur door and window bottom or well lid in the door and window process is subjected to stopping of out-of-flatness or out-of-level ground surface, the height that its hinge axis makes progress does not change in rotary door window, so can not fully open door and window, even jammed phenomenon takes place.

Summary of the invention

But the purpose of this utility model is to provide a kind of hinge of hinged thing folding automatic lifting, door and window or well lid are when screwing switching, on the axial height of hinge, can raise or reduce, make the lower end of door and window or well lid soffit keep away out-of-flatness or out-of-level surface, folding smoothly.

But the utility model is achieved in that a kind of hinge of hinged thing folding automatic lifting, by rotating shaft Upper shaft sleeve and Lower shaft sleeve are installed, the lower ending opening inclined-plane of Upper shaft sleeve and the upper end open inclined-plane of Lower shaft sleeve are for rotating movingly, on the Upper shaft sleeve affixed last fixed arm be fixed on the door and window or and on affixed well lid, affixed following fixed arm is fixed on doorframe and window frame Joint or and the borehole wall Joint on the body of wall on the Lower shaft sleeve.

The key of the utility model structure is to be cooperated by two openend phase rotational slides with inclined-plane, the door and window or the well lid that are connected with last fixed arm is risen or decline on the inclined-plane, thereby can not be subjected to out-of-flatness or out-of-level surface barrier under door and window or the well lid; Can learn that from said structure the utility model is then used wider, practical more flexibly, door and window or well lid are when screwing switching, on the axial height of hinge, can raise or reduce, make door and window, car door or well lid soffit keep away out-of-flatness or out-of-level surface, folding smoothly.
