Inward-opening and inward-reversing back lock
The invention relates to the technical field of doors and windows, in particular to an inward-opening and inward-reversing back lock which comprises a sash upper fixing plate, the sash upper fixing plate is connected with a door and window sash profile, a rotating hole is formed in the lower portion of the sash upper fixing plate, and an elastic body is arranged above the rotating hole; a rotating arm is arranged at the top of the upper sash lock catch, the rotating arm is connected with the rotating hole of the upper sash fixing plate in a matched mode so that the rotating arm can rotate along the rotating hole, the positioning face of the top of the rotating arm makes contact with the elastic body in the upper sash fixing plate, and a first connecting block is arranged on one side of the upper sash lock catch; a clamping strip is arranged on the first connecting block in the direction close to the inner side, a second connecting block is arranged on the other side of the sash upper lock catch, and a gap is reserved between the second connecting block and the first connecting block. Compared with the prior art, the door and window sash profile has the advantages that after the door and window sash profile and the door and window frame profile are automatically locked, the clamping groove and the clamping strip are designed, and after the clamping groove and the clamping strip are clamped, wind pressure can be resisted, and air leakage and rain leakage are avoided.
本发明涉及门窗技术领域，具体来说是一种内开内倒背锁，包括扇上固定板，所述扇上固定板与门窗扇型材连接，所述扇上固定板下部设有旋转孔，旋转孔上方设有弹性体；扇上锁扣，所述扇上锁扣顶部设有旋转臂，所述旋转臂与扇上固定板的旋转孔配合连接，以使旋转臂能沿旋转孔转动，所述旋转臂顶部定位面与扇上固定板内的弹性体接触，所述扇上锁扣一侧设有第一连接块，所述第一连接块靠内侧方向设有卡条，所述扇上锁扣另一侧设有第二连接块，所述第二连接块与第一连接块之间留有间隙。本发明同现有技术相比，其优点在于：门窗扇型材与门窗框型材自动锁住之后，设计有卡槽和卡条，卡槽和卡条卡住后，可抗风压，避免漏风漏雨。
