In addition, the body 2 is provided with the pressing type elastic self-locking mechanism 24, as shown in fig. 2, the corresponding position on the door frame 15 of the door body 1 is provided with the clamping piece 151, as shown in fig. 5 or fig. 8, when the door needs to be closed, the clamping piece 151 of the door body 1 is clamped on the pressing type elastic self-locking mechanism 24 of the body 2, when the door needs to be opened, the door body 1 can move towards the pressing type elastic self-locking mechanism 24, and rotates around the hinge part, that is, the door body 1 is closed by pressing once, and can be opened by pressing once again when the door is opened.

The door body assembly 10 further comprises a repulsive force part 4 arranged at the end face 26, the repulsive force part 4 can generate a repulsive force as the name suggests, and has a tendency of preventing the door body 1 from continuously moving towards the body 2, so that when the door body 1 is close to a door frame of the body 2, the speed is gradually reduced, and the problem that the door body 1 violently collides the body 2 to generate a large collision sound is avoided. So when closing the door, repulsion portion 4 has the trend of ordering about a body 1 and keeping away from body 2, has slowed down the rate of motion of a body 1 when closing the door, and when a body 1 will be opened under the closure condition, because the prerequisite continues to move to body 2 direction, presses once again promptly, but this repulsion portion 4 has the trend of ordering about a body 1 and keeping away from body 2, so make a body 1 colluded by push type elasticity self-locking mechanism 24 throughout very tightly, avoid a body 1 to be opened by accident's problem.

The repulsive portion 4 includes a first repulsive portion 4a and a second repulsive portion 4b, the first repulsive portion 4a is close to the hinge base, and the second repulsive portion 4b is close to the pressing type elastic self-locking mechanism 24, as shown in fig. 5. The repulsion part 4 is arranged at the hinge seat and the pressing type elastic self-locking mechanism 24, so that better shock absorption can be realized in multiple directions when the door body 1 is closed. Specifically, as the first repulsive portion 4a is close to the hinge seat, the door body 1 is in contact with the first repulsive portion 4a at the fastest time when closing, the first repulsive portion 4a blocks the continuous inward movement of the door body 1, and when the door body 1 is about to be closed and connected with the pressing type elastic self-locking mechanism 24, the second repulsive portion 4b close to the pressing type elastic self-locking mechanism 24 forms a second wave block, so that the trend of inward movement of the door body 1 is further slowed down, and the noise is reduced.

Further, the first repulsive portion 4a includes a first flexible piece 41a protruding from the end surface 26, and the second repulsive portion 4b includes a second flexible piece 41b protruding from the end surface 26, as shown in fig. 5 and 10, when the door body 1 is switched from the open state to the closed state, the first flexible piece 41a and the second flexible piece 41b are pressed by the door body 1 and the door frame; the first flexible part 41a and the second flexible part 41b can be made of rubber or silica gel, and a repulsive force effect is generated through the deformation and the tendency of recovery deformation of the flexible parts.

In addition, in the closed state, the first flexible piece 41a is pressed by the door body 1 and the door frame, and the distance from the end far away from the end surface 26 of the first flexible piece 41a to the end surface 26 is longer than the distance from the end far away from the end surface 26 of the second flexible piece 41b to the end surface 26. The arrangement is that the position for generating larger repulsive force to the door body 1 is in the direction of the hinge seat, so that the force on one side of the door body 1 close to the second repulsive force part 4b is smaller, the door body can be pressed towards the body 2 continuously in a closed state, the door body 1 is convenient to open, and the phenomenon that the door body 1 cannot be pressed towards the body 2 due to too large force at the position is avoided.

Further, as shown in fig. 10, each of the first and second repulsive force portions 4a and 4b includes a guide rod 42, an anti-drop member 43, and a fixing groove 44 formed between the anti-drop member 43 and the first or second flexible member 41a or 41b, an opening 261 for passing through the guide rod 42 and the anti-drop member 43 is provided on the door frame, as shown in fig. 3 and 4, the opening 261 is caught in the fixing groove 44, the anti-drop member 43 blocks the first or second repulsive force portion 4a or 4b from leaving the opening 261, the anti-drop member 43 has a slope directed toward the guide rod 42, the opening 261 is easily accessible from the guide rod 42 side, but is hardly moved in the opposite direction. When the anti-dropping device is installed, all the repulsive force parts 4 are inserted into the opening 261 from one end of the guide rod 42 from the end face 26 until the opening 261 is clamped in the fixing groove 44, and at this time, the repulsive force parts 4 can be accurately fixed under the action of the anti-dropping piece 43.

In this embodiment, referring to fig. 5, the repulsive force portions 4 are respectively disposed at the upper end and the lower end of the door assembly 10, the pressing type elastic self-locking mechanism 24 is disposed at the middle position of the door assembly 10, so that the repulsive force portions 4 are prevented from being too close to the pressing type elastic self-locking mechanism 24, and the door 1 cannot be pressed inward at the position of the pressing type elastic self-locking mechanism 24, so that the door cannot be popped out, and a distance from the pressing type elastic self-locking mechanism 24 to the repulsive force portions 4 is enough to generate a certain deformation to open the door 1, and in addition, the symmetric steps can buffer the door 1 in all directions to prevent violent collision when the door is closed.

Mechanical analysis:

the head of the upper bolt 112 is hung above the upper hinge seat 22, an upward force is applied to the rotating shaft 11, so that the rotating shaft 11 cannot fall off, the lower bolt 113 fixes the rotating shaft 11 below the lower hinge seat 21, so that the rotating shaft 11 cannot be lifted, and when the refrigerator is transported to generate an inclination trend, the rotating shaft 11 cannot be separated out, so that the rotating shaft 11 is fixed; the rotating shaft 11 is arranged in the cavity 12, and the cavity 12 is a cavity formed in the door frame 15, so the rotating shaft 11 plays a role in preventing the door body 1 from overturning, but the supporting part for supporting the door body 1 at the bottom is born by the first rotating connecting piece 13, so the structure has small force effect on the rotating shaft 11, and the door body 1 only needs to rotate around the rotating shaft.
