Description

An anti-falling device for outward opening windows

technical field

The utility model belongs to the technical field of door and window design, in particular to an anti-dropping device for an outward opening window.

Background technique

Aluminum alloy doors and windows are used in construction. Outward opening windows are popular products. Outward opening windows have the advantages of not occupying indoor space after opening and have good sealing effect. However, the sash of outward opening windows will be damaged after long-term use. There is a safety hazard that the window sash falls off outwards. As shown in Figures 1 and 2, the four-bar linkage mechanism 1 is connected to the outward-opening window sash, and the mounting strip 4 is fixed on the window frame panel 7 by screws. When the outward-opening window sash reciprocates for a long time When opening and closing, it is easy to make the connection point of the installation strip 4 and the window frame panel 7 loose and damaged, causing the sash to fall off; Various anti-falling devices have emerged as the times require, and the existing anti-falling devices are generally more complicated, requiring corresponding modification of the window frame, which increases the manufacturing cost and reduces the use range of the window frame.

Further, the end of the installation bar (4) is provided with a strip-shaped slot (5); the rivet (2) is hinged in the strip-shaped slot (5).

Further, the fixing plate (31) is provided with a reinforcement hole (34); the reinforcement hole (34) is fixed on the window frame panel (7) by bolts.

Further, the thickness of the fixing plate (31) is greater than the depth of the notch (6) of the window frame.

Further, the thickness of the locking plate (32) is not greater than the depth of the notch (6) of the window frame.

The beneficial effects of the utility model:

The utility model has the advantages of simple structure, convenient and fast installation, and does not need to modify the window frame. The plates are connected by rivets and can be relatively movable, which improves the tensile strength.
