Description

Large angle folding and unfolding hinge for suspension window

Technical Field

The utility model relates to window opening and closing transmission hardware, in particular to a large-angle opening and closing suspension window hinge.

Background

Ordinary window of hanging is the transmission that opens and shuts through hardware connecting pieces such as sliding support, hinge, and the most common spout on the market is one kind by slide rail, slider, top support cantilever, short support cantilever, hold in the palm the cantilever and long support cantilever equipment the sliding support hinge that forms: the short supporting cantilever and the supporting cantilever are correspondingly hinged with the sliding block and then are arranged in the sliding rail; the short supporting cantilever, the top supporting cantilever, the long supporting cantilever and the sliding rail are correspondingly hinged to form a moving mechanism. A guide vertex angle is arranged at one end of the sliding rail, and plays a role in guiding the opening and closing of the hinge. A pair of sliding supports are arranged on the casement window, and when the window sash is pushed, the force is transmitted to the moving mechanism by the window sash through the supporting cantilever arranged on the window sash. Because the sliding block can slide in the sliding rail, the moving mechanism moves under the action of force, so that the window sash can be opened and closed. Practical window of this kind of structure sliding support or hinge, the angle of opening receives the restriction of slider sliding distance, can only open about 30 usually, influences the ventilation effect of in-service use, and the effort between long-time back slider and the slide rail weakens, also can reduce the window fan support dynamics, leads to the casement can not keep the open mode. There is also a cancellation slider, slide rail structure, directly sets up the arc wall on the window frame installed part, sets up spacing post on short support cantilever, through the cooperation between spacing post and the arc wall, realizes the restriction of the angle that opens and shuts, and this kind of structure needs fluting on the sliding support spare part, influences holistic stability, directly leads to spout bearing capacity to descend.
