Translational airtight door and window

Abstract

The invention discloses an airtight sliding window. The airtight sliding window comprises a window frame, a sash, rolling wheel assemblies, a handle and a transmission mechanism; the rolling wheel assemblies are arranged on an upper frame of the sash and a lower frame of the sash correspondingly; each rolling wheel assembly is provided with a guide mechanism for performing push-pull guide on the sash as well as a translation mechanism for driving the sash to translate perpendicular to the sash push-pull direction; the handle is pivoted with the sash and is linked with one end of the transmission mechanism; the other end of the transmission mechanism is in transmission connection with the translation mechanism; the sash performs push-pull movement in the length direction of the window frameand translates in the direction perpendicular to the sash push-pull direction through the translation mechanism. The translation movement among the sashes can be controlled through the handle, the gap is reduced and the airtightness is enhanced.

Description

technical field [0001] The invention relates to a window, in particular to a translational airtight door and window. Background technique [0002] A sliding window is a sash opening or closing that is realized by two or more sashes pushing and pulling each other. Whether it is a unilateral door leaf push-pull or a pair of door leaf push-pull, since two sashes need to overlap to provide the window to open and realize the opening of the sliding window, therefore, two The gap between the sashes is large, otherwise the two sashes are likely to interfere during the push and pull process. However, precisely because of the large gap, it is easy to form a gap between the two sashes in the closed state to allow water or wind to enter. As a result, the doors and windows are not closed tightly, and the gap is easily further enlarged by wind and rain, forming a vicious circle. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of th...
