AI Technical Summary
Existing hinges can cause cabinet doors to spring back quickly when users forcefully open them, potentially causing injury to users. Furthermore, the cabinet doors may close again, posing a safety hazard.
A door opening rebound resistance point is set on the outer rocker arm. The sum of the radius of the second moving pin and the center distance from the door opening rebound resistance point to the first moving pin is greater than the center distance between the first and second moving pins. The door opening rebound resistance point prevents the second moving pin from rebounding, thereby reducing the door rebound strength.
It effectively reduces the amplitude and speed of cabinet door rebound, improves safety, and avoids collision injuries caused by violent cabinet door rebound.

Abstract
Claims
1. A swing mechanism against door opening rebound, comprising an outer rocker arm (2) and an inner rocker arm (3) for connecting a hinge arm (1) and a hinge cup (4), characterized in that: It also includes a first moving pin (7) for hinged to the outer rocker arm (2) and the hinge cup (4) and a second moving pin (8) for hinged to the inner rocker arm (3) and the hinge cup (4). The outer rocker arm (2) is provided with a door opening rebound obstruction point (9) for contacting the second moving pin (8). The sum of the radius of the second moving pin (8) and the distance from the door opening rebound obstruction point (9) to the center of the first moving pin (7) is greater than the center distance between the first moving pin (7) and the second moving pin (8). The door opening rebound obstruction point (9) can pass over the second moving pin (8) relatively back and forth.
2. The swing mechanism of claim 1, wherein: The door opening rebound obstruction point (9) is integrated with the outer rocker arm (2).
3. The swing mechanism of claim 2, wherein: The outer rocker arm (2) has a convex corner (202) formed thereon, and the door opening rebound resistance point (9) is formed at the tip of the convex corner (202).
4. The swing mechanism of claim 3, wherein: The convex corner (202) has a rounded corner (2021) at the tip.
5. A swing mechanism according to claim 3 or 4, wherein: The outer rocker arm (2) includes an arm body (20). An opening limit recess (21) is formed between the convex corner portion (202) and the arm body (20). The second movable pin (8) can swing around the first movable pin (7) to the opening limit recess (21).
6. The swing mechanism of claim 5, wherein: The door opening limiting recess (21) is adapted to the second moving pin (8).
7. The swing mechanism of claim 5 wherein: The door opening limiting recess (21) forms a limiting recess entrance end (2101), and the door opening rebound obstruction point (9) is continuously distributed from the limiting recess entrance end (2101) to the corner tip of the convex corner (202).
8. A hinge comprising a hinge arm (1) and a mounting base (10), characterized in that: The swing mechanism for preventing door opening and rebound as described in any one of claims 1 to 7, wherein the hinge arm (1) is disposed on the mounting base (10), and the outer rocker arm (2) and the inner rocker arm (3) are respectively hinged to the hinge arm (1).
