The specific embodiment

Below in conjunction with accompanying drawing and a preferred embodiment the utility model is described in further detail, to help understanding content of the present utility model.

As depicted in figs. 1 and 2, a kind of reinforced sliding support hinge is made up of slide rail 2, first slide block 3 and a plurality of hinged holder cantilever that are installed in the slide rail.Described holder cantilever comprises a long holder cantilever 5, between first slide block 3 and long holder cantilever 5 front ends, be hinged with a short holder cantilever 4, long holder cantilever 5 middle parts are hinged with slide rail 2 by one the 3rd holder cantilever 7, perhaps with slide rail in one second slide block (omitting among the figure) hinged can change articulated position easily.One the 4th holder cantilever 6 one ends are hinged on the 3rd holder cantilever 7 middle part other ends and are hinged on described first slide block 3, and slide rail 2 front ends are equipped with guiding drift angle 1.

In conjunction with Fig. 1, Fig. 3 and shown in Figure 4, be positioned on the described long holder cantilever 5 hinged pin joint 51 both sides of long holder cantilever and the 3rd holder cantilever 7 respectively have along its length direction one stamp out downwards above recessed protruding

elongated slot

52,53 formation reinforcing ribs, here be up and down consistent with above-below direction among Fig. 2.Reinforcing rib makes this pin joint and length hold in the palm the counter-bending deformability enhancing of part between the cantilever installing hole like this, and owing to be top recessed protruding structure, assurance length asks cantilever to fit tightly with the frame of the sash of fixing.

Same reason, as shown in Figure 1, on described the 3rd holder cantilever 7 at least its with the pin joint of the 4th holder between the cantilever 6 to the 3rd position of holding in the palm between the hinged pin joint of cantilever and slide rail 2 (or second slide block), along its length direction have one upwards stamp out below above recessed protruding elongated slot 71 form reinforcing ribs, by shown in Figure 2 since the 3rd the holder cantilever 7 be crooked, so elongated slot form following recessed above protruding structure make whole the 3rd the holder cantilever 7 the constant hinge arrangement compactness that helps of overall height.But below certainly elongated slot 71 adopts protruding above recessed structure also be shape, by between the holder cantilever that is hinged, increasing pad so that it separates certain interval can avoid holding in the palm between the cantilever rubbing.
