Description

Technical Field

[0001] The utility model relates to a window and door hinge, in particular to a hinge with a multi-position switching function. Background Art

[0002] Doors and windows are traditional components in buildings, which play relatively basic but very important functions such as ventilation, odor dissipation, heat preservation, heat insulation, sound insulation, waterproofing, fire prevention, and wind prevention in buildings. Only by realizing the above functions can people be guaranteed to be in a comfortable living, working, and learning environment.

[0003] The structures of traditional doors and windows are as follows: They include a fixed frame and a rotating component. The fixed frame is hollow, and the rotating component is used to close the hollow part of the fixed frame. The fixed frame and the rotating component are connected by a hinge. The traditional hinge has the following problems: The position of its hinge point is fixed. Therefore, the door or window can only rotate around the hinge point with a fixed position. Limited by the door, window, and the surrounding environment, there will be working dead corners in the use of the door or window, which makes traditional doors and windows have obstacles in specific scenarios. For example, it is inconvenient to clean; when an emergency event such as a fire occurs, the door or window cannot be opened at a sufficient angle to facilitate people's fire escape; when there is strong wind outside, the doors and windows cannot be closed to a suitable position to balance the ventilation and wind prevention needs indoors. Summary of the Invention

The end with a larger area of the second spring 603 abuts against the second button 602, and the end with a smaller area of the conical spring abuts against the sliding rail 5.

[0041] The pull rod 1 is rotatably connected to the first sliding part 8 through the first adapter handle 9. One end of the pull rod 1 close to the sliding rail 5 is rotatably connected to one end of the first adapter handle 9, and the other end of the first adapter handle 9 is slidably connected to the first sliding part 8. The pull rod 1 is rotatably connected to the second sliding part 6 through the second adapter handle 2. The middle part of the pull rod 1 is rotatably connected to one end of the second adapter handle 2, and the other end of the second adapter handle 2 is slidably connected to the second sliding part 6. A third adapter handle 3 is further included. One end of the third adapter handle 3 is rotatably connected to the first sliding part 8, and the other end of the third adapter handle 3 is rotatably connected to the second adapter handle 2. A fourth adapter handle 4 is further included. One end of the fourth adapter handle 4 is rotatably connected to the pull rod 1, and the other end of the fourth adapter handle 4 is rotatably connected to the third adapter handle 3.

[0042] A sliding part limiting block 7 is further included. The sliding part limiting block 7 is located on the side of the second sliding part 6 facing the first sliding part 8, and the sliding part limiting block 7 is fixedly connected to one end of the second sliding part 6 facing the first sliding part 8.

[0043] A vertex angle 503 is provided at any one end of the sliding rail 5. End limiting blocks 502 are provided at both ends of the sliding rail 5. A limiting screw 505 for limiting the first sliding part 8 is provided in the middle of the sliding rail 5.

[0044] The pull rod 1 is fixedly connected to the top or bottom of the movable part of the door or window to drive the movable part to rotate. The sliding rail 5 is fixedly connected to the inner side of the top or bottom of the fixed frame of the door or window.

[0045] The principle of the first sliding part 8 being locked by the first notch 504 is as follows: In the unlocked state, the limiting edge 501 extends into the first inner groove 8011 and limits the first limiting block 8021 of the first button 802 along the longitudinal direction. The first button 802 (the first limiting block 8021) has an upward elastic force under the action of the first spring 803. When the first sliding part 8 slides to the first notch 504, the first notch 504 releases the limit on the first limiting block 8021 along the longitudinal direction. The first limiting block 8021 enters the first notch 504 upward and interferes with the sliding direction of the slide rail 5. Thus, the first sliding part 8 is locked by the first notch 504. When it is necessary to release the limit on the first sliding part 8, just press the first button 802 downward. The height of the first limiting block 8021 is lower than that of the limiting edge 501, and the first sliding part 8 can then slide along the slide rail 5.

[0046] The second sliding part 6 is the same as the first sliding part 8.

[0047] As Figure 14 shown, in the first working state of the present utility model, at this time the first sliding part 8 is locked by the first notch 504. After pressing the second button 602 in the second sliding part 6, the limit of the second notch 506 on the second sliding part 6 can be released. The pull rod 1 (i.e., the movable part of the door and window) rotates as the active source. The pull rod 1 drives the second sliding part 6 to slide. When the left side of the sliding part limiting block 7 abuts against the first sliding part 8, the door and window is opened to the maximum position. In the first working state position, the maximum opening area of the door and window can be achieved, which is convenient for people to enter and exit and for fire escape.

[0048] As Figure 15 shown, in the second working state of the present utility model, the pull rod 1 (i.e., the movable part of the door and window) rotates as the active source to close. The pull rod 1 drives the second sliding part 6 to slide until the second sliding part 6 is locked by the second notch 506. The second working state can achieve a small-angle opening of the door and window, control the ventilation size, and at the same time prevent people from accidentally falling.

[0049] As Figure 16 shown, the space between the movable part of the door and window and the end is small in the first working state and the second working state, which is not convenient for cleaning the door and window. Therefore, the present utility model can enter the third working state. The first notch 504 releases the lock on the first sliding part 8, and the first sliding part 8 slides to the right until it is limited by the limit screw 505. At this time, the space between the pull rod 1 (i.e., the movable part of the door and window) and the left end becomes larger, which is more convenient for cleaning.
