Abstract

The invention relates to an automatic window closing device. The automatic window closing device comprises a shell, an inner partition plate, a first elastic piece, a telescopic rod, a limiting rod, aconnecting rod, a water-swelling device, a first fixing device and a second fixing device. The first elastic piece is located in the shell, one end of the first elastic piece is connected with the shell, the other end of the first elastic piece is connected with the telescopic rod, the other end of the telescopic rod is connected with the first fixing device, and a groove is formed in the telescopic rod. The inner partition plate is located in the middle of the interior of the shell and divides the internal space of the shell into an upper space and a lower space, and a hole is formed in themiddle of the inner partition plate. One end of the limiting rod is connected with the connecting rod, the other end of the limiting rod penetrates through the hole in the inner partition plate and ismatched with the groove, the limiting rod and the groove are matched to limit the length of the portion, extending out of the shell, of the telescopic rod, the connecting rod is connected with the water-swelling device, and a water leakage hole is formed in the upper side of the water-swelling device. The second fixing device is connected with the shell. The automatic window closing device is suitable for casement windows, automatic window closing of the casement windows can be achieved in rainy days, rainwater is prevented from entering a room, and the automatic window closing device is simple in structure, easy to install and easy and convenient to use and maintain.

Description

technical field [0001] The invention relates to the technical field of industrial and civil construction, in particular to an automatic window closing device. Background technique [0002] In people's daily life, generally the windows are opened and the indoor air is better, but the weather conditions change at any time. Once it rains and there is no one at home, it is impossible to close the windows in time. It will enter the house, wet the walls, furniture, floors, etc., and may even accumulate water, causing losses to the family.
