Abstract

The invention relates to the field of fittings for building doors and windows, and particularly discloses a lifting-assisting device for an aluminum alloy internal flat-opening hopper window. The lifting-assisting device for the aluminum alloy internal flat-opening hopper window comprises a base cushion fixed on a slot opening in the bottom of a sash through inner hexagonal fastening screws B and is characterized in that a base A is fixed on a slot opening, corresponding to the base cushion, in the bottom of a window frame, a base B is connected to the base A through a cross recessed countersunk head screw, an idler wheel arranged through a small shaft is arranged between the base A and the base B, and a guide surface corresponding to the idler wheel is arranged on the base cushion. The lifting-assisting device has the advantages of reasonable structure design, convenience for installation and use, small window opening and closing forces, accuracy in selected materials, long service life, more humanized design, and wide application range.

Description

(1) Technical field [0001] The invention relates to the field of fittings for building doors and windows, in particular to a lifting device for aluminum alloy inner casement and lower hung windows. (2) Background technology [0002] With its excellent thermal insulation, air tightness, water tightness and wind pressure resistance, the inner casement bottom hung window has been widely promoted and applied in my country, and it has played an important role in the construction of our country and the improvement of people's living environment quality. At the same time, it has also made a great contribution to the energy saving and consumption reduction of public and civil buildings in my country, especially the saving of heating energy consumption and air conditioning energy consumption. With the deepening of building energy-saving work and the promotion of building energy-saving implementation of 75% indicators, door and window technology is constantly improving and improvin...
