AI Technical Summary

Technical Problem

The existing tilt-and-turn window's tilt-and-turn locking device has gaps in the locking position, causing problems such as shaking and poor bottom sealing.

Method used

The system employs a hinge transmission mechanism and a locking transmission mechanism. The hinge transmission mechanism provides power to allow the locking limit part and the inward tilting limit part to rotate within the bottom edge of the fan body and the guide rail of the frame, thereby achieving stable locking and inward tilting positioning of the fan body. The locking positioning is achieved by utilizing the self-contained guide rail of the frame, which simplifies the locking structure and enhances the sealing performance.

Benefits of technology

It achieves stable locking and improved sealing performance of the fan body, simplifies the locking structure, reduces the space occupied by the locking transmission mechanism on the frame, and enhances the sealing effect.

Abstract

The application provides a transmission device and a window body, the transmission device comprises a hinge transmission mechanism and a locking transmission mechanism, one end of the hinge transmission mechanism is fixed at an angle position between a side edge of a sash body and a bottom edge of the sash body, the other end of the hinge transmission mechanism is slidingly connected to a bottom edge guide rail of a frame body, and the locking transmission mechanism is arranged on the bottom edge of the sash body; the locking transmission mechanism comprises a translation assembly and a locking assembly, one end of the translation assembly is used for connecting the hinge transmission mechanism, the hinge transmission mechanism is used for applying an action force to the translation assembly to make the translation assembly slide in a sash groove of the bottom edge of the sash body, and the other end of the translation assembly is connected to the locking assembly; the locking assembly is provided with a locking limiting part which can extend into the guide rail of the frame body. The locking limiting part is matched with the bottom edge guide rail of the frame body, the locking and positioning of the sash body are directly realized by using the guide rail of the frame body, other locking seat structures are not needed to be additionally arranged for cooperation, the locking structure can be simplified, and the occupied area of the locking transmission mechanism on the frame body is reduced.
