Description
Technical field
This utility model is related to the attachment means of door and window, and in particular to a kind of significantly sliding door and window built-in hinge.
Background technology
Chinese patent, notification number are CN203961559U, in a kind of entitled Easy dismountable with load-bearing enhancing structure
The patent of falling hinges of door and window in opening, including window frame attachment structure and window attachment structure, window frame attachment structure pass through hinge arrangement and
Window attachment structure connects, and forms Telescopic push-and-pull door and window structure；Window frame attachment structure includes window frame articulated slab and is arranged on window
At least two rigid shackle members and at least two active connections on frame articulated slab, rigid shackle member are located at window frame articulated slab
Inner side, forms fixed interface arrangment of the main load receiving part of window frame articulated slab to window frame, and active connection is positioned in window frame articulated slab
Outside, form the activity adjustment formula attachment structure to window frame to the secondary load receiving part of window frame articulated slab；Rigid shackle member directly from
The bottom surface of window frame articulated slab is stretched out, and the bottom surface of window frame articulated slab is formed in one or be fixedly connected on window frame articulated slab, is formed
Load-bearing to window frame strengthens interface arrangment；Active connection is rotatably arranged on the bottom surface of window frame articulated slab, and active connection is interior
Mode tumbler, the activity adjustment formula attachment structure by rotation regulation formation to window frame.
Wherein, rigid shackle member is to extend square bending block from window frame articulated slab bottom surface, and square bending block is in " L "
Shape, is formed draw-in groove between the bending part of square bending block and the bottom surface of window frame articulated slab, is connected with window frame screens by draw-in groove
Connect the fixed interface arrangment main load receiving part of window frame articulated slab is formed to window frame；Active connection is driven by eccentric rotor and interior corner
Dynamic formula rotating shaft is constituted, and interior corner drive-type rotating shaft is fixedly installed on window frame articulated slab, and the rotation of interior corner drive-type rotating shaft is adjusted
Above window frame articulated slab, eccentric rotor is located at the bottom surface of window frame articulated slab the power with interior corner drive-type rotating shaft at end
Outfan is fixedly connected, and forms movable clamp groove between the bottom surface of eccentric rotor and window frame articulated slab, and the movable clamp groove is formed to window
The activity adjustment formula attachment structure of frame.Due to adopting rigid bottom surface of the shackle member directly from window frame articulated slab to stretch out, cut with scissors with window frame
Fishplate bar is formed in one or is fixedly connected on the bottom surface of window frame articulated slab, and forming the load-bearing to window frame strengthens interface arrangment；Activity
Connector is rotatably arranged on the bottom surface of window frame articulated slab and forms the activity adjustment formula attachment structure to window frame, strengthens clamping by load-bearing
Structure and activity adjustment formula attachment structure support the weight of window jointly, and weight capacity is strong；When installing and using, only need to be by rigid card
Fitting is connected on window frame and turns two active connections again window can be stably connected with window frame, when shortening installation
Between.
Due to being the interior mode with interior corner drive-type rotating shaft with the active connection of window frame attachment structure in above-mentioned technology
Rotational structure, its regulative mode between window are to extend transversely in the groove of doorframe to drive in corner using internal angle wrench
Interior angle through hole twisting on dynamic formula rotating shaft riveted joint is adjusted.There is defect following aspects：1st, the activity of window frame attachment structure
Connector is interior mode rotational structure, adjusts inconvenient and cannot check regulation angle position so that active connection is difficult to send out
Existing clamping position, easily occurs the situation for there be not clamping or clamping not in place occur because regulation is not in place.2nd, activity adjustment part and window
Easily there is the phenomenon of vibrations resilience, i.e. activity adjustment part four in the extraneous vibration effect lower edge to rotate connection in frame articulated slab
Angle drive-type axis of rotation and offset origin-location, cause potential safety hazard.3rd, in prior art, the general maximum of window articulated slab is beaten
Angle of release degree is 90 °, it is impossible to wall of fitting, and is made troubles to actually used.4th, when window is closed in the windowing of existing Hinge for window and door frictional force compared with
Little, when blowing there is potential safety hazard in the little inertia of resistance big then easy " beating window ".5th, the mobile regulative mode of existing window fine setting is
Extend transversely into regulation regulation inconvenience is brought to site operation.
Utility model content
