The window is a light and thin wall structure that can move vulnerable parts, it is the weakest link in the building enclosure structure. Among them, the hinge as the main load-bearing part of flat open doors and Windows, plays a very important role in building doors and Windows, performance and service life directly affects the safety of the doors and Windows. Building doors and Windows security problem, the key lies in the connection of the fan and casing hinge of door window is there enough bearing capacity, the hinge is the level of decision is a very key factor. As the main load-bearing component of the open doors and Windows, it is widely used in most of our country. It is not only the use of hinges in doors and Windows, but also public buildings such as glass doors are widely used (the structure is different, of course). This paper analyzes the force of the hinges and establishes the mechanical analysis model. Second, the mechanical analysis of the hinges When calculating the hinge force many hardware companies both at home and abroad, often only the influence of the weight of door to door, and the stress of the actual door casement hinge and a key factor, is the influence of wind pressure. According to the specific situation of the force of the hinges, the two aspects of gravity direction and wind pressure are divided into consideration. Two pages. (1) gravity direction Suppose: the distance from the top and bottom to the edge of the fan is x meters, and the two hinges are the same page, as shown in figure 1. It can be concluded tha
