Adjustable parallel push-out type slide supporting hinge

Abstract

The invention discloses an adjustable parallel push-out sliding stay hinge, which comprises two pairs of supporting cantilevers and two parallel sliding rails, each sliding rail is respectively equipped with two sliding blocks, and each pair of supporting cantilevers includes two intersecting Hinged support cantilever, one end of each pair of support cantilevers is fixedly connected to the slide rail through a fixed block, and the other end is hinged with the sliders of the two slide rails, the fixed block has a mounting hole, and the upper part of the fixed block is higher than that of the slide rail The upper folded edge forms a supporting surface for the support cantilever. The support cantilever assembled on the top plane of the fixed block in the present invention is not easy to tilt under the action of external force, which prevents the support cantilever from contacting the upper folded edge of the slide rail in the process of opening and closing the sash , friction, making the product open and close smoothly and durable.

Description

technical field [0001] The invention relates to a hinge, in particular to an adjustable parallel push-out sliding stay hinge. Background technique [0002] At present, the commonly used parallel push-out sliding stay hinge is composed of a slide rail, a slider and a support cantilever: one end of the two support cantilevers is respectively hinged to one end of the two slide rails, and the other ends of the two support cantilevers are respectively hinged to the slider and then installed. Enter two slide rails to form an X-shaped motion mechanism, so that the parallel movement between the two slide rails can be realized. When used for large and heavy windows, on the basis of increasing the length of the slide rail, one or more pairs of supporting cantilevers and sliders can be added to form a parallel push-out sliding stay hinge with double X or even multiple X structures. [0003] The parallel push-out sliding stay hinge of the double X structure formed in this way has the f...

Problems solved by technology

[0003] The parallel push-out sliding stay hinge of the double X structure formed in this way has the following disadvantages: 1. Due to the dimensional error, it will affect the coordination of the movement rods (cantilever) and slider movement of the double X mechanism, resulting in double X mechanism The movement is not synchronous and parallel, and the force and wear of each moving rod (supporting cantilever) and slider are inconsistent, which not only leads to the imprecise closing of the window and the unsmooth opening and closing of the window sash, but also the inconsistency of wear will be further aggravated The asynchronous movement of the double X mechanism forms a vicious circle, which eventually leads to the inability of the double X mechanism to move, which greatly reduces the service life of the parallel push-out sliding stay hinge of the double X structure; It will not only cause the bending and unevenness of the slide rail, so that the sliding of the slider in the slide rail is not smooth, but also because its top plane is small (the top plane must be higher than the upper edge of the slide rail, the cantilever will not be blocked when it rotates. The upper flanges on both sides of the slide rail are blocked, so the diameter or width of the top plane will be smaller than the width between the upper flanges on both sides of the slide rail, and then the rounded corners at the turning point will be deducted, and the top plane will be even smaller), assembled in The support cantilever of the top plane is easy to tilt under the action of external force, and will contact and rub against the upper edge of the slide rail during the process of opening and closing the window sash. Not only is it difficult to open and close the window sash, but the sliding support hinge is easily damaged due to wear and tear.
