Security structure applied on lower-part load-bearing door and window

Abstract

The invention provides a security structure which is reasonable in structure, capable of preventing a door leaf from falling off and hurting people, and safe and reliable; the security structure comprises an upper guide rail, a lower guide rail, the door leaf and a roller wheel which is arranged under the door leaf and stands on the lower guide rail; the upper part of the door leaf leans against the upper guide rail; and a safety device is arranged between the upper part of the door leaf and the upper guide rail. The safety device is arranged between the upper part of the door leaf and the upper guide rail, and the safety device can be a stand column, a hook or the like, so that when the door leaf is deformed when being applied with external force (such as wind pressure, collision and the like), or the roller wheel falls off from the lower guide rail, the upper guide rail is supported or hooked respectively by the stand column or the hook, and the door leaf is ensured not to fall off; and due to the simple and reasonable structure, the potential safety hazard of sliding doors and windows can be eliminated, and the safety performance of the sliding doors and windows can be enhanced; and therefore, the security structure has remarkable progress.

Description

technical field [0001] The invention relates to a door leaf structure, in particular to a safety structure applied to lower load-bearing doors and windows. Background technique [0002] At present, the commonly used doors and windows are divided into swing doors, spring doors, sliding doors, folding doors, revolving doors, rolling doors, etc. according to the opening and closing methods. The conventional structure of sliding doors and windows is that the bottom of the door leaf is equipped with rollers, and the rollers are arranged on the lower guide rail. The top of the door leaf is connected with a positioning companion wheel. The positioning companion wheel leans vertically on the upper guide rail, and the door leaf moves between the upper and lower guide rails. Since the entire door leaf is supported by the rollers, the upper end of the door leaf only rests on the upper guide rail. When the door leaf is subjected to external forces (such as wind pressure, impact, etc.) t...

AI Technical Summary

Problems solved by technology

Since the entire door leaf is supported by the rollers, the upper end of the door leaf only rests on the upper guide rail. When the door leaf is subjected to external forces (such as wind pressure, impact, etc.) to deform the door leaf or the rollers fall off the lower guide rail, the upper end of the door leaf is easy to fall off The upper guide rail falls off and hurts people, which is a big safety hazard and needs to be improved
