Safe type slip support hinge

Abstract

This is a safety slide support hinge. It contains: Slide track, slide block, and some suspending arms they are joined together. The slide block is installed in the slide track and can slide in it by fricative motion: Its features are: On the slide block there are safety button-up device. When the block slide in its moving procession reach to middle position, the safety button-up device can fix block on the track tightly.

Description

technical field [0001] The invention relates to a hinge, in particular to a safety sliding stay hinge for windows, which can realize self-locking to prevent it from being opened and closed in an undesired manner. Background technique [0002] The sliding brace hinge used on the existing windows is assembled from a slide rail, a slider and a number of mutually hinged support cantilevers. The support cantilever and the slider are hinged accordingly and then loaded into the slide rail; It is also hinged accordingly to form a motion mechanism. One end of the slide rail is equipped with a guide top angle, which guides the opening and closing of the hinge. The working principle of this kind of sliding stay is as follows: a pair of sliding stay hinges are installed on the window. Slide in the slideway, so the kinematic mechanism moves under the force, so that the window sash can be opened and closed. [0003] Since this kind of sliding stay hinge does not have a safety self-lock...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a safety type sliding stay hinge, which can limit the opening angle of the window sash in a certain middle position, to solve the above-mentioned safety problem that the existing sliding stay hinge cannot limit the opening angle of the window sash in the middle position. The opening angle of the position prevents it from being opened and closed in an undesired way, making it safer and more reliable to use
