The torsion spring 19 is sleeved on the outside of the rotating shaft 18, and one end of the torsion spring 19 is connected to the edge of the spring limiting housing 17, and the other end of the torsion spring 19 is connected to the rotating shaft 18;

[0025] A rubber gasket 20 is provided on the rear side of the connector 14 .

[0026] See Figure 1-Figure 4 As shown, the button-type buckle structure includes a button mounting part 4 installed in the refrigerator body 1, a buckle 6 is vertically slidably installed in the button mounting part 4, and a spring 7 is provided between the top of the buckle 6 and the button mounting part 4; a movable groove 8 is provided at the top of the front side of the buckle 6, and a slope surface 9 is provided above the movable groove 8; several sliding rods 10 are provided in the button mounting part 4, a button 5 is movably provided in front of the button mounting part 4, and several sliding seats 12 matching the sliding rods 10 are provided on the back of the button 5, each sliding rod 10 is slidably installed in the sliding seat 12, and a spring 2 13 is provided between the sliding seat 12 and the sliding rod 10; a driving head 11 is provided in the middle position of the back of the button 5, the upper end of the driving head 11 is a slope, and the driving head 11 is movably provided in the movable groove 8.

[0027] The principle and use process of this utility model:

[0028] When the buckle 6 is stuck in the bayonet 3, that is, in the locked state, when the refrigerator door 2 needs to be opened, the button 5 is first pressed. The button 5 slides inward along the sliding rod 10 while squeezing the second spring 13, and the inclined head of the driving head 11 pushes the slope 9 of the buckle 6 inward, thereby pushing the buckle 6 upward and compressing the first spring 7. The buckle 6 is separated from the bayonet 3, that is, the limiting effect on the refrigerator door 2 disappears, the torsion spring 19 rebounds, and at the same time cooperates with the action of gravity to realize the automatic opening of the refrigerator door 2. After opening, the first spring 7 and the second spring 13 both rebound and push the button 5 and the buckle 6 back to their original positions;

[0029] During the opening process of the refrigerator door 2, the refrigerator door 2 drives the connector 14 and the rotating shaft 18 to rotate. At the same time, the damper 16 decelerates the rotation of the rotating shaft 18, and the rotating shaft 18 applies a reaction force to the rotating shaft 18, thereby causing the refrigerator door 2 to slowly descend. When the refrigerator door 2 is fully opened, the rubber gasket 20 in the connector 14 contacts the outer shell of the hinge structure 15, thereby absorbing the impact generated when the door is opened, thereby preventing noise caused by the impact.

[0030] When the refrigerator door 2 needs to be closed, the refrigerator door 2 is rotated upward. During this process, the torsion spring 19 is compressed, and the refrigerator door 2 first pushes the buckle 6 upward. Then, when the buckle 6 is opposite to the bayonet 3, the spring 17 pushes the buckle 6 into the bayonet 3, and the refrigerator door 2 is limited and closed.

[0031] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
