The utility model discloses an superiority is found several points:

1. in view of traditional aluminum alloy outer flat-open window receives section bar section structure to influence, has metal "heat bridge" phenomenon, the utility model discloses in, install the hardware in the five metals notch, window locking piece and hinge, five metals function notch are designed to the indoor side by outdoor side adjustment, have avoided the problem of locating formation metal "heat bridge" at the handle. Because the hardware notch design is indoor, the opening angle of the outward opening fan can be influenced. In order to ensure that the window sash has a larger opening space and is connected by the hinge, the problem of ventilation and water seepage occurs at the broken part of the adhesive tape at the hinge, and in order to avoid the problem, the hinge is used for replacing the exposed hinge for connection at the hinged part of the window sash, so that the physical performance of the whole window is ensured, and the opening angle of the outward opening window can have a reasonable range.

In addition, the locking hardware mechanism and the sliding support of the common outward-opening window are supported in the outdoor side, when the outdoor side of the combustion chamber is in the high temperature, the aluminum profiles and the heat insulation strips in the outdoor side can be combusted, melted or deformed, so that the locking mechanism of the whole window is disabled, and flame or smoke can enter the indoor space quickly. The utility model discloses put five metals locking mechanism in indoor side, do not influence indoor one side when outdoor side burning to delay whole window and warp or damage, play the guard action.

2. The sectional design is optimized, when the window is closed, the outer surfaces of the first fin wall 11 and the first fin wall 31 are flush with the indoor side face of the window sash 2, and the outer surface of the second fin wall 21 is flush with the indoor side faces of the mullion 3 and the window frame 1, so that the visual faces of the indoor and outdoor side frames of the aluminum alloy outer casement window are flush, and the aluminum alloy outer casement window is more attractive.

3. Change traditional frame fan overlap joint mode and be the isobaric design of three sealings, the frame fan overlap joint mode of considering traditional aluminum alloy outer flat-open window is mostly sealed twice, and the overlap joint position is single cavity structure, has heat loss such as convection current, the utility model discloses in, second joint strip 52 and third joint strip 53 design have realized three sealings and isobaric design on the casement. The constant pressure cavity is divided into an indoor side and an outdoor side, so that the cavity is added, the air convection is blocked, and the heat loss is reduced. Meanwhile, when the window sash is closed, the third sealing rubber strip 53 on the window sash is in a state of being overlapped on the window frame indoors, and when the third sealing rubber strip 53 is also under the wind and rain pressure, the third sealing rubber strip 53 is under the acting force of the outdoor side to the window frame, and the overlapping of the third sealing rubber strip 53 and the window frame 1 is increasingly tight. Meanwhile, the physical properties such as the watertight property and the airtight property of the whole window are improved, and the problems of lap joint gaps and the like caused by the aging of adhesive tapes are solved.

The utility model discloses in, can also break off two little breachs on second joint strip 52 upside, the watertight chamber that forms like this under rainwater pressure can communicate with each other with the external world, makes cavity and ambient pressure balanced, realizes isobaric principle. Under the conventional state, the cavity on the outer side can be sealed, air convection is reduced, and the heat preservation performance is improved.

The basic principles, main features and advantages of the present invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
