Friends are on the door and window decoration, everyone knows what is the aluminum alloy door and window hardware accessories ? Now the decoration of the home network Xiaobian will come to everyone to say the aluminum alloy door and window hardware accessories knowledge, what are our aluminum alloy door and window hardware accessories? Things, and the true use of these aluminum alloy door and window hardware accessories, I hope that these aluminum alloy door and window hardware accessories can help friends. 1. What are the aluminum alloy door and window hardware accessories? 1, the window opener The window opener is used to open the high position ventilation window. The opening part of the window can determine the width of the window opening. Its deformation determines the ability of the window opener to adapt to different window types and different installation conditions. The operating member can be in the form of a handle or rocker. There is also a manual window opener, which is suitable for opening the window in the hanging and overhanging. 2, door closer The door closer is characterized by a slow closing speed and no collision sound when it is closed. The door closer is used in high-end hotels, and its function is equivalent to the double-spring hinge, which can automatically close the door and window after opening. 3, hinge When selecting a hinge, the ball bearing in the middle shaft is selected, and the gloss of the paint and plating determines the flexibility and noise of the drawer switch. 4, handle The material of the handle is mainly stainless steel, copper and the like. Moreover, the shape of the handle is relatively diverse. When choosing a handle, it is necessary to choose according to the style of home decoration, and also choose to bear a large handle, so as to play a protective role, so that the home is in a safe state. 5, the latch The pin is a small part whose main function is to prevent the anti-theft component from being opened by the outside. The structure is simpler than the lock, except that it is locked outside the door and the latch is inside the door. Second, the use of aluminum alloy door and window hardware accessories 1. After the aluminum alloy was used in the manufacture of windows, people developed sliding windows. The sliding window has no problem with the stopper at all, because the sash of the sliding window is basically the same when it is opened and closed. 2. One disadvantage of the sliding window is that there must be at least one fixed fan, which greatly reduces the window opening area: another fatal weakness is that the airtightness and watertightness requirements cannot be achieved at all. 3. The fixed point of the sash of the sliding window is the upper and lower guide rails, so the wind pressure resistance is also limited. Modern buildings are increasingly demanding energy-saving and other functions, and have strict requirements on window sealing and heat insulation, air tightness and water tightness, sound insulation and wind resistance, and even anti-theft level. In order to achieve various comprehensive requirements, an inwardly tilted window, or a European window, is produced. 4. The window type on the modern glass curtain wall building is related to the fixing method of the window frame on the curtain wall. Due to the high requirements for airtightness, watertightness and wind resistance of glass curtain walls, the components of the curtain wall are developed relatively independently as needed. 5. The windows of modern buildings are not limited to the level of manpower. Starting from the requirements of ventilation and heat removal, the height of the windows is an important factor in determining the efficiency of ventilation and heat removal. Therefore, various window openers have been invented. 6, the general stainless steel door and window hardware life is more than 8 years, good hardware looks very thick, and the surface gloss is good, the protective layer is dense, no scratches, the most important point is that the opening should be flexible. All of the above are the specific contents of our aluminum alloy door and window hardware accessories, and what are the real uses of our aluminum alloy door and window hardware accessories, friends now have some understanding of aluminum alloy door and window hardware accessories, Everyone continues to pay attention to our decoration home network to learn more about decoration.
