The closing assembly 2 is installed between the swing door and the door frame 1 for automatically closing the outwardly opening swing door. The buffer assembly 3 includes a fixed frame 34 and a buffer frame 35. The fixed frame 34 is fixedly mounted on the door frame 1, and a buffer spring and a buffer pad are installed inside the fixed frame 34. The two ends of the buffer spring are connected to the inner side of the fixed frame 34 and the buffer pad, respectively. The buffer frame 35 is fixedly mounted on the upper side of the swing door, and an outwardly protruding buffer plate 36 is fixedly mounted inside the buffer frame 35. When the door is closed, the buffer pad abuts against the buffer plate 36, and the buffer frame 35 fits against the edge of the fixed frame 34.

[0023] Multiple sets of buffer springs and buffer pads are provided inside the fixed frame 34. Each buffer spring is connected to a buffer pad, and the buffer springs are evenly spaced. The initial lengths of the multiple buffer springs are different, so that the distance between the buffer pads and the fixed frame 34 is different. Along the horizontal direction towards the opening of the swing door, the distance between the buffer pads and the fixed frame 34 increases proportionally. In this embodiment, there are a first buffer spring 31, a second buffer spring 32, and a third buffer spring 33 arranged in sequence; the first buffer spring 311, the second buffer spring 321, and the third buffer spring 331 are respectively connected to the buffer springs; the first buffer spring 31 is the shortest and the third buffer spring 33 is the longest.

[0024] The buffer plate 36 has a trapezoidal structure, with the inclined surface of the buffer plate 36 facing the fixed frame 34 and the inclined surface pointing downwards in the horizontal direction towards the opening of the swing door.

[0025] The door closer assembly 2 includes a door closer body 21, a connecting rod 22, a rotating shaft 23, a rocker arm 24, and a support 25. The door closer body 21 is mounted on a swing door. One end of the connecting rod 22 is rotatably connected to the door closer body 21, and the rotating shaft 23 is fixedly mounted on the other end of the connecting rod 22. The rocker arm 24 is located on the upper side of the door closer body 21, and one end of the rocker arm 24 is rotatably connected to the upper end of the rotating shaft 23. The rocker arm 24 is a telescopic rocker arm. The other end of the rocker arm 24 is fixedly connected to the support 25, and the support 25 is mounted on the door frame 1. It should be noted that in this embodiment, the door closer body 21 is a conventional door closer, and the specific connection relationships and working principles of its internal hydraulic cylinder, spring, piston, gears, and other devices are not described here.

[0026] The door closer body 21 is detachably connected to the door via bolts, and the support 25 is detachably connected to the door frame 1 via bolts. Preferably, the connecting rod 22, the pivot 23, the rocker arm 24, and the support 25 are made of aluminum alloy.

[0027] In this embodiment, the support assembly 4 includes a support plate 41, a first blocking plate 42, a return spring 43, a side frame 44, and a second blocking plate 45. The support plate 41 is detachably mounted on the upper side of the fixed frame 34. One end of the first blocking plate 42 is rotatably connected to the upper side of the support plate 41 via a pin. The side frame 44 is fixedly mounted on one end of the support plate 41 and has an internal slot. The return spring 43 is disposed between the first blocking plate 42 and the side frame 44. One end of the return spring 43 is fixedly connected to the inner side of the side frame 44, and the other end is fixedly connected to the outer side of the first blocking plate 42, thereby resetting the first blocking plate 42 so that it is perpendicular to the fixed frame 34. The second blocking plate 45 is fixedly mounted on the upper side of the buffer frame 35. When the fixed frame 34 and the buffer frame 35 are in contact, the contact surfaces of the first blocking plate 42 and the second blocking plate 45 abut against each other.

[0028] Working principle:

[0029] When the door closing assembly 2 rebounds and closes the swing door, as the swing door gradually approaches the door frame 1, the buffer plate 36 and the buffer pad abut against each other, the second blocking plate 45 abuts against the first blocking plate 42, the first blocking plate 42 rotates towards the return spring 43, and the buffer pad buffers the swing door until the edges of the fixed frame 34 and the buffer frame 35 are in contact. This can reduce the impact between the swing door and the door frame 1 when it rebounds and closes, so that the swing door gradually decelerates when closing, reduces the noise generated between the swing door and the door frame 1, and avoids damage to the door lock.
