Thus, when the door leaf 61 performs a door closing action and comes into contact with the door frame 62, the cushioning member is caused by the interlocking of the movable platen 34 and the spring 35. 31 provides the function of the brake buffer, mitigating the impact force of the door leaf 61 and the door frame 62, effectively reducing the impact sound when the door is closed, and additionally, when the door closing action is completed and the rest is present, the movable platen 34 is automatically restored by the tension of the spring 35 to make the door leaf 61 and the door frame 62 have a close contact state, which is advantageous for the production of functions such as airtight sound insulation. Thus, the cushioning member 31 is installed at the interface of the door frame 62, and has the same functional effect as the device at the interface of the door leaf 51. .

The double-opening door is a door structure with two door leaves. The door leaf can be separately opened and closed, or two door fans can be simultaneously opened and closed to provide access to the larger objects, and the interface between the door frame and the door leaf. The buffer member 31 can be installed in the foregoing manner, and the interface in which the two door leaves are in contact is the most important impact position during the door closing process. Therefore, at the interface where the two door leaves are in contact, the installation of the cushioning member 31 is a double-opening door. Focus.

Referring to FIG. 7, the door frame 71 corresponds to the door leaf 72, and the cushioning member 31 can be simultaneously disposed. Thus, when the door closing 71 is brought into contact with the door leaf 72 when the door closing operation is performed, the function of the movable platen 34 and the spring 35 is designed. The utility model provides the functions of double buffer brakes, etc., and can effectively reduce the impact sound when the door is closed. In addition, when the door closing action is completed and the static state is completed, the function of the movable platen 34 and the spring 35 is automatically restored, so that the door frame 71 and the door leaf 72 are provided. Between the production of the cushioning member 31, a tighter contact state can be achieved. Thus, when the buffer frame 31 is installed at the position corresponding to the door leaf 72 and the door leaf 72, the cushioning brake and the airtight soundproofing of the door structure are achieved. And other functional design, you can get the effect of multiplication.

Corresponding to the two door leaves of the double door, the buffer member 31 can be installed at the same time to provide the function of buffer brake and airtight sound insulation of the double door, and the effect of multiplication can be obtained.

Referring to Fig. 8, the cushioning member 81 is also provided with a grooved outer casing 82, a movable platen 83 and a spring 84, and the like, and the focus is on the contact surface 85 of the movable platen 83, which is coated with a gas-tight glue having a function of a rubber gasket. In accordance with the mounting method described in the preceding section, the buffer member 81 is disposed at the interface between the door leaf and the door frame. When the door closing operation is performed, the door and the door frame can avoid direct collision of the rigid material by the production of the airtight rubber strip 86. The action of closing the door can reduce the impact sound more effectively, and at the same time, when the door closing action is completed and the static state is completed, the plasticity essence of the airtight rubber strip 86 and the force applied by the spring 84 and the movable pressure plate 83 are restored. Between the door leaf and the door frame, the cushion member 81 is kept in closer contact, so that the airtight sound insulation effect of the door structure can be better produced.
