Abstract
The utility model discloses a sliding-supporting hinge for a safety type window with the function of reducing the wear of the sharp-end contact surface in opening and closing. The sliding-supporting hinge comprises a connecting-rod moving mechanism in the prior art, wherein a guiding vertex angle comprises a side-surface guiding surface and a bottom-surface installing surface; the side-surface guiding surface comprises guiding working surfaces at the two sides and a flat-bottom groove which is positioned between the guiding working surfaces and is concave towards one side far away from a sliding rail; bending points a are arranged at the connecting position between guiding working surfaces and the flat-bottom groove; the guiding vertex angle is symmetrically arranged at one end of the sliding rail by adopting the central line of a sliding-rail installing hole as a symmetric axis; when a window sash is closed, the sharp corner at the head part of a top-part supporting cantilever can be fixed by means of the bending points so as to realize complete closing of the window sash and shorten the friction distance from a to b; since an expanded angle A of the two sides of the guiding vertex angle is large (an included angle between one guiding working surface and the central line of the sliding-rail installing hole is 75-85 degrees), the depth H of each guiding working surface is less, and the sharp angle at the head part of the top-part supporting cantilever can more easily enter the guiding vertex angle to reduce the contact of the sharp angle of the head of the top-part supporting cantilever with the guiding working surfaces of the guiding vertex angle is reduced, so that the wear is reduced.
Description
Technical field
The utility model relates to a kind of hinge means for headstock gear, especially a kind of safety type window sliding support hinge of most advanced and sophisticated contact surface abrasion while reducing to open and close.
Background technology
Conventional emergency escape safety type window sliding support hinge is to be assembled in the following manner by slide rail 1a, slide block, some holder cantilevers and guiding drift angle 2a at present: short holder cantilever, holder one end of cantilever and one end respective hinge of slide rail 1a; After one end of slide block and long holder cantilever is hinged, pack the middle part of slide rail 1a, long holder cantilever into and the other end of hinged, the long holder cantilever of the other end of holder cantilever is hinged with the middle part of top holder cantilever 4a, the head of cantilever 4a is held in the palm at top and the other end of short holder cantilever is hinged, composition bar linkage motion mechanism, wherein except short holder cantilever, top holder cantilever 4a, long holder cantilever and holder cantilever are the step structure with one-level ladder, be this cross-coupled needs on the one hand, and upper surface entirety is located in one plane after these multiple holder cantilevers link together; Guiding drift angle 2a is assemblied in the end of slide rail 1a one end, the unlatching to sliding support hinge, closed guiding, the positioning action of rising.A pair of emergency escape safe type slip support hinge is installed on to (guiding drift angle 2a is near one end of window frame) on window, in the time opening sash, sash moves toward opening direction by the top holder cantilever 4a drivening rod motion that is installed on sash, slide block can be slided or reverse slide towards one end of guiding drift angle 2a by the other end guide away from guiding drift angle 2a, drive sash one end near window frame in rotating toward opening direction, the distance of sash and the window frame other end is maximized, be convenient to escape in the time of breaking out of fire or other emergencies.
But conventional emergency escape safe type slip support hinge has following shortcoming: with reference to Fig. 1, in the time that sliding support hinge is closed into a certain degree, the wedge angle 40a of top holder cantilevered head starts to withstand and slide along the guiding work plane of guiding drift angle 2a, until sliding support hinge is completely closed, and the side guide face of present guiding drift angle 2a by two guiding work planes form parabola shaped, as depicted in figs. 1 and 2, angle between two guiding work planes is larger, the degree of depth of guiding work plane is darker, in the time that sliding support hinge is closed completely, the wedge angle 40a of top holder cantilevered head overlaps with the central point of guiding work plane, and top holder cantilever installing hole center line and slide rail installing hole center line the (see figure 2) that also overlaps, this certainly will cause the wearing and tearing of wedge angle 40a and the guiding work plane of top holder cantilevered head, along with opening and closing the increase of number of times, wearing and tearing increase, finally cause Window closing imprecision even cannot close, affect the application life of window.
In view of this, special the utility model that proposes.
