[0042] See also Figure 6-Figure 10The working principle of the spring steel cable 1 assembly structure for doors and windows of this embodiment is as follows: the window in this embodiment includes a window body 3, a common auxiliary frame 4 and a reinforced auxiliary frame 5, which are connected in sequence, and a plurality of the above-mentioned elastic assemblies 2 are arranged in the window, and a transition plate 222 supporting a transition piece 22 is fixedly arranged on the reinforced auxiliary frame 5. At this time, the first elastic piece 21 and the first limiting piece 11 are located in the common auxiliary frame 4, the first limiting piece 11 is connected to the common auxiliary frame 4, and the second elastic piece 23 and the second limiting piece 12 are located in the reinforced auxiliary frame 5. When an earthquake occurs, there are generally three situations, one of which causes the doors and windows to be moved. When the earthquake causes the window 3 to swing left and right, under the action of the vertical earthquake wave parallel to the plane of the window 3, when the earthquake causes the window 3 to swing to the left, the window 3 deviates to the left. Since the overall length of the steel cable 1 is constant, the first elastic member 21 in the elastic assembly 2 on the left contracts and the second elastic member 23 extends, and the first elastic member 21 in the elastic assembly 2 on the right extends and the second elastic member 23 contracts, thereby reducing the damage to the doors and windows caused by the earthquake and achieving an earthquake-resistant effect. When the earthquake causes the window 3 to swing right, the window 3 deviates to the right. Since the overall length of the steel cable 1 is constant, the first elastic member 21 in the elastic assembly 2 on the left contracts and the second elastic member 23 extends. 21 stretches and the second elastic member 23 contracts, the first elastic member 21 in the elastic assembly 2 on the right side contracts and the second elastic member 23 stretches, thereby reducing the damage to the doors and windows caused by the earthquake and achieving an earthquake-resistant effect. The situation where the window 3 swings up and down is consistent with the above-mentioned action process and is not repeated here; the other is to cause the doors and windows to swing inside and outside. Under the action of horizontal seismic waves perpendicular to the plane of the window 3, when the earthquake causes the window 3 to swing toward the room, the window 3 deviates toward the room. At this time, the second elastic member 23 keeps a constant position, and the first elastic member 21 drives the steel cable 1 to swing toward the room. Then, due to the action of the first elastic member 21, the first elastic member 23 moves toward the room. The elastic member 21 can drive the steel cable 1 to return to its initial position, thereby reducing the damage to doors and windows caused by the earthquake and achieving an earthquake-resistant effect; when the earthquake causes the window 3 to swing toward the outdoors, the window 3 shifts toward the outdoors. At this time, the second elastic member 23 maintains a constant position, and the first elastic member 21 drives the steel cable 1 to swing toward the outdoors. Then, due to the action of the first elastic member 21, the first elastic member 21 can drive the steel cable 1 to return to its initial position, thereby reducing the damage to doors and windows caused by the earthquake and achieving an earthquake-resistant effect. Under the action of multi-dimensional seismic waves (horizontal seismic waves and vertical seismic waves act simultaneously), the swinging of the window 3 is consistent with the above-mentioned action process.

[0043] The spring steel cable assembly structure for doors and windows of this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the spring steel cable assembly structure for doors and windows provides elasticity and support to reduce the impact of earthquakes on doors and windows through the close cooperation of the steel cable 1 and the elastic assembly 2, thereby providing a strong guarantee for the safety of buildings and the lives of people.
