[0021] Please refer to Figures 1-4 , an embodiment provided by the present invention: A double-rabbet airbag sound insulation washer for a wooden door body, including: a sub-door main body 1 and a mother-door main body 2. Sub-door rabbet ends 3 and mother-door rabbet ends 4 are respectively arranged at the adjacent ends of the sub-door main body 1 and the mother-door main body 2. A rabbet sound insulation pad 5 is arranged between the sub-door rabbet end 3 and the mother-door rabbet end 4. A plurality of grooves 6 are formed on the outer wall of the rabbet sound insulation pad 5. A limit frame 7 is arranged inside the groove 6. A pressing groove 14 is formed inside the limit frame 7. A first airbag pad 9 is arranged inside the pressing groove 14. A plurality of delivery channels 15 are arranged on both sides below the first airbag pad 9. A second airbag pad 10 is arranged at one end of the delivery channel 15 away from the first airbag pad 9. A plurality of protruding pressing blocks 12 are arranged on the outer wall of the sub-door rabbet end 3. A plurality of card slots 13 matching the first airbag pad 9 are arranged on both sides of the pressing block 12. The diameters of the second airbag pad 10 and the card slot 13 are 1-3 cm. The shapes of the second airbag pad 10 and the card slot 13 are any one of regular polygons and circles. Airbag pads of different sizes can be selected for combination based on door panels of different sizes; the mother-door main body 2 is rotated and opened and closed through a hinge. When it is closed, its mother-door rabbet end 4 will fit with the sub-door rabbet end 3. By arranging the rabbet sound insulation pad 5 at this place, the impact force generated when the door body is closed can be reduced, and the noise caused by the impact can be reduced. At the same time, the sealing performance and sound insulation effect of the rabbet end can be improved during daily use. Among them, when it is closed, the pressing block 12 moves into the pressing groove 14 and presses down the first airbag pad 9, and the gas in the first airbag pad 9 is filled into the second airbag pad 10 through the delivery channel 15, so that the second airbag pad 10 inflates and expands in the card slot 13, which can effectively improve the sealing performance at the rabbet and improve the sound insulation effect. When it is opened later, the pressing block 12 disengages from the pressing groove 14, so that the first airbag pad 9 is no longer pressed, and part of the gas enters the first airbag pad 9 again through the delivery channel 15, and the second airbag pad 10 shrinks accordingly, making it easier to disengage from the card slot 13.

[0022] Please refer to Figure 2 , Figure 3An assembly groove 8 is provided between the groove 6 and the limiting frame 7, an assembly frame 11 matching the assembly groove 8 is provided on the periphery of the pressing block 12, and the second airbag cushion 10 includes an elastic rubber 17, an airbag cavity 16 is provided inside the elastic rubber 17, and one end of the airbag cavity 16 is connected to the conveying channel 15; in the closed state, the assembly frame 11 will be pressed into the assembly groove 8 to further improve the stability of the stop, and at the same time, through the restrictions of the assembly frame 11 and the limiting frame 7, the pressing block 12 is easily aligned and pressed into the pressing groove 14; the elastic rubber 17 has good elasticity and can expand and contract according to the changes of the airbag cavity 16;

[0023] Furthermore, the shape of the stop sound insulation pad 5 is a stepped structure that matches the stop end 3 of the sub-door and the stop end 4 of the main door, and the material of the stop sound insulation pad 5 is sound insulation rubber; the sound insulation rubber is the stop sound insulation pad 5 which can effectively reduce the impact force generated when the stop of the sub-door and the main door is closed, and it has elasticity and can be tightly sealed between the two stop ends to improve the sealing and sound insulation effects. It has a low cost and can reduce the subsequent replacement cost. The stepped structure can fully soundproof and seal the contact surfaces of the stop end 3 of the sub-door and the stop end 4 of the main door, further improving the sealing and sound insulation effects. The structure is built into the stop and will not affect the appearance of the entire door body too much in the closed state, thereby improving the aesthetics.

[0024] Working principle: When in use, the main body 2 of the mother door realizes the rotating opening and closing operation through the hinge. When it is closed, the stop end 4 of the mother door will fit with the stop end 3 of the sub-door. When closed, the pressure block 12 moves into the pressure groove 14 and presses down the first airbag cushion 9, and the gas in the first airbag cushion 9 is filled into the second airbag cushion 10 through the conveying channel 15, so that the second airbag cushion 10 is inflated in the card slot 13, which can effectively improve the sealing of the stop and improve the sound insulation effect. When it is opened subsequently, the pressure block 12 is separated from the pressure groove 14, so that the first airbag cushion 9 is no longer pressurized, and part of the gas enters the first airbag cushion 9 again through the conveying channel 15, and the second airbag cushion 10 is further reduced, making it easier to separate from the card slot 13; in the closed state, the assembly frame 11 will be pressed into the assembly combination groove 8, further improving the stability of the stop. At the same time, through the restriction of the assembly frame 11 and the limit frame 7, the pressure block 12 is easily aligned and pressed into the pressure groove 14.
