Inward falling sliding window

Abstract

The invention discloses an inward falling sliding window which comprises an outer frame, a sash, an upper swing arm, a swing positioning part and a drive link. A positioning check block capable of being popped up or retracting is arranged on a positioning seat of the swing positioning part; the positioning seat is provided with an inclined slide and a positioning sliding block; one end of the positioning sliding block is provided with a notch coincided with the positioning check block; one end of the upper swing arm is arranged on the sash; the other end of the upper swing arm is rotatablely arranged in an outer frame groove; when the positioning check block is popped up, the upper swing arm is stopped by the positioning check block, so that the upper swing arm can only rotate along the circle center of the upper swing arm; the drive link is provided with an eccentric lock pin; one side of the positioning sliding block is provided with a sliding block port; when the eccentric lock pin extends into the sliding block port, the drive link is matched and linked with the positioning sliding block; and when the eccentric lock pin is separated from the sliding block port, the drive link and the positioning sliding block are separated from each other. When the swing positioning part directly and synchronously moves together with the eccentric lock pin on the drive link and the positioning check block takes a positioning effect, the sash is in an open and closed state; when the sash falls inward, the positioning check block does not take the effect and the positioning check block gives way to enable the upper swing arm to move to fulfill the aim of falling inward, so that the sash can be enabled to be opened, closed or fall inward freely.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to an inwardly sliding window. Background technique [0002] At present, there are mainly two types of doors and windows: casement and push-pull. Especially in severe weather, such as stormy weather, the window can only be opened or closed, which cannot make the indoor air and the outside effectively convect, and cannot meet the needs of people to breathe fresh air. Therefore, the sash in a window frame can not only be pushed and pulled, but also can realize the function of inversion on its upper part. It is a sliding window with a relatively complicated structure. . However, the existing sliding window swing positioning parts are prone to deviation errors when the transmission rod is driven, or the locking pin on the transmission rod and the swing positioning part transmission contact failure due to the excessive gap between the sash leads to failure of the swing positi...

AI Technical Summary

Problems solved by technology

However, the existing sliding window swing positioning parts are prone to deviation errors when the transmission rod is driven, or the locking pin on the transmission rod and the swing positioning part transmission contact failure due to the excessive gap between the sash leads to failure of the swing positioning. In the end, the opening and inversion of the window sash will fail, and the adjustment is troublesome. The size of the window sash is too large and the size is limited, and the production accuracy is high.
