[0024] Furthermore, one side of the flip beam 2 is inserted into the flip groove 101 and is rotatably connected via the flip shaft 201 , and the linkage mechanism on the refrigerator refrigerating chamber door 1 drives the flip beam 2 to rotate 90 degrees via the flip shaft 201 .

[0025] Furthermore, when the flip beam 2 rotates to a position parallel to the refrigerator refrigerator door 1, one side of the first rectangular limit strip 102 and one side of the second rectangular limit strip 202 fit together to limit the position, ensuring that the flip beam 2 remains parallel to the refrigerator refrigerator door 1 when the refrigerator refrigerator door 1 is closed, preventing the flip beam 2 from excessive deflection.

[0026] Furthermore, each limiting column 3 is provided with a telescopic groove 301, and a communicating exhaust hole 302 is provided between one side of the telescopic groove 301 and one side of the front end surface of the limiting column 3. When the telescopic column 4 moves inside the telescopic groove 301 of the limiting column 3, air is introduced into and exhausted into the telescopic groove 301 through the exhaust hole 302 to ensure smooth movement of the telescopic column 4. A limiting round rod 303 is fixedly connected to the middle part of the telescopic groove 301.

[0027] Furthermore, a telescopic column 4 is connected to the telescopic slot 301 of each limiting column 3, one end of the telescopic column 4 extends through the telescopic slot 301 to the outside and is fixedly connected to a top cap 5, a buffer slot 401 is provided on one side of the middle part of the telescopic column 4, a buffer spring 402 is provided inside the buffer slot 401, one side of the buffer slot 401 is connected to a circular limiting slot 403 in the middle part of the telescopic column 4, and a circular opening 404 is provided between the other side of the buffer slot 401 and the end face of one side of the telescopic column 4.

When the refrigerator refrigerator door 1 is opened, the linkage mechanism drives the flip beam 2 to rotate through the flip shaft 201 again. When the rear end surface of the flip beam 2 deflects, it contacts and pushes the top cap 5, causing the top cap 5 to push The movable telescopic column 4 is retracted into the buffer groove 401, and the limiting round rod 303 moves into the circular limiting groove 403 at the same time. The upper limit ring 304 of the limiting round rod 303 moves to one side in the buffer groove 401 to compress the buffer spring 402, so as to buffer the top cap 5 between the rear end surface of the flip beam 2. When the flip beam 2 rotates backward 90 degrees, the telescopic column 4 is completely retracted into the buffer groove 401 at the same time, and one side of the top cap 5 is fitted and limited with one end of the limiting column 3.
