Door and window frame connecting device of sliding-plug translation inward tilt-turn door and window

Abstract

The invention provides a door and window frame connecting device of a sliding-plug translation inward tilt-turn door and window, and belongs to devices on building doors and windows. An installation cavity is arranged in the middle of an installation cavity body, a swing support arm is further involved, the head end of the swing support arm is installed in the installation cavity through a first rotating shaft, a swing seat fixed on the side face of the head end of the swing support arm is hinged to a spring cavity through a second rotating shaft, a spring is installed in a spring installationgroove in the spring cavity, the end of the spring is installed on a transverse column on the side face of a drum, the drum is installed in the installation cavity through a third rotating shaft, andthe tail end of the swing support arm is provided with a connecting shaft hole. When in use, the connecting device is reasonable in structure and can be matched with a corresponding connecting deviceinstalled on a door and window sash, folding closing and ejection of the swing support arm can be assisted by elastic force of the spring, action is smooth, operation saves labor, and the using effect is good.

Description

technical field [0001] The invention relates to a device on a door and window of a building, in particular to a device on a sliding door and window of a Sierra translation. Background technique [0002] There are two kinds of Sierra translation doors and windows for buildings at present, one can only Sierra translation, and the other can not only Sierra translation but also inward micro-ventilation. Its used door and window frame connecting device has poor structural rationality, just connects a torsion spring on the movable support arm, has only elastic function, does not have closing return function, switch is not smooth, common people are not easy to operate, and use effect is poor. And the two groups of rollers on the upper part of the existing door and window frame connection device can only stop the swing and cannot bear the load, and only the two groups of rollers on the lower part are loaded by force, which will easily cause the lower end interlocking pulley to be ov...

AI Technical Summary

Problems solved by technology

The structure of the door and window frame connection device used is poor in rationality. It is only connected to a torsion spring on the movable support arm, which only has the function of springing out, without the function of closing and returning. The switch is not smooth, it is difficult for ordinary people to operate, and the use effect is poor

Moreover, the two sets of rollers on the upper part of the existing door and window frame connection device can only stop the swing and cannot bear the load, and only the two sets of rollers on the lower part bear the force, which will easily cause the lower connecting pulley to be overstressed, resulting in damage and deformation and cannot be used

In summary, the use effect of the existing Sierra sliding door and window frame connection device is relatively poor
