In order to solve the problems of too complicated structure and inconvenient use of the refrigerator door control device, the refrigerator door control device comprises an upper hinge assembly 21, a self-locking groove 31, a second limiting block 32 and a shaft sleeve 33, wherein the upper hinge assembly 21 is arranged at the upper end of a refrigerator body 1 of a refrigerator, the self-locking groove 31 and the second limiting block 32 are arranged at the upper end of a door body 3, the shaft sleeve 33 is arranged on the second limiting block 32, the upper hinge assembly 21 is movably connected with the shaft sleeve 33, the upper hinge assembly 21 is provided with a self-locking block 23, the self-locking block 23 is a downward protrusion, an elastic component is arranged at the bottom of the self-locking groove 31, and when the door body 3 and the refrigerator body 1 are in a closed state, the self-locking block 23 is positioned in the self-locking groove 31 and is in elastic contact with the elastic component.
As shown in FIG. 2, the refrigerator door control device is partly installed on the upper end of the refrigerator body 1 and partly on the upper end of the refrigerator door 3. The upper hinge assembly 21 is arranged at the upper end of the refrigerator body 1, the self-locking groove 31, the second limiting block 32 and the shaft sleeve 33 are arranged at the upper end of the refrigerator door body 3, the shaft sleeve 33 is arranged at the position closest to the side edge of the refrigerator door body 3, the shaft sleeve 33 is movably connected with the hinge assembly 21, and when the refrigerator door body 3 rotates, the self-locking groove 31, the second limiting block 32 and the shaft sleeve 33 rotate along with the refrigerator door body 3. The self-locking mode of the bottom of the existing door body 3 is moved to the top, so that only the hinge shaft hole is reserved in the end cover at the bottom of the door body 3, the assembly is simplified, and meanwhile, a space is provided for the design of a handle with a narrower edge.
When the refrigerator door is in a closed state, the self-locking position block 23 is positioned in the self-locking groove 31 and presses an elastic member arranged at the bottom of the self-locking groove 31, the elastic member is pressed downwards, the self-locking position block 23 is locked, and therefore the refrigerator door is fixed through the self-locking position block 23 and the self-locking groove 31.
In some embodiments, the sleeve 33 is provided with a second protrusion 331 which is downward vertically, the second protrusion 331 has a hollow structure, an outer circumference of a cross section of the second protrusion 331 is square, and an inner circumference of a cross section of the second protrusion 331 is circular. The second limiting block 32 is provided with a square hole, and the shaft sleeve 33 is connected with the second limiting block 32 through the square hole and the second protrusion 331.
The second limiting block 32 is fixed at the upper end of the door body 3 through a screw, and the shaft sleeve 33 is connected with the second limiting block 32 through a square hole, so that the shaft sleeve 33 can be better fixed. When the refrigerator door is rotated, the shaft sleeve 33 is movably connected with the upper hinge assembly 21, friction is generated between the shaft sleeve 33 and the upper hinge assembly 21, the periphery of the cross section of the shaft sleeve 33 is square, relative rest can be ensured between the shaft sleeve 33 and the second limiting block 32, and the shaft sleeve 33 cannot rotate due to the friction between the inner wall and the upper hinge assembly 21.
In some embodiments, the door further includes a first stopper 25, the first stopper 25 extends downward along a direction perpendicular to the upper hinge assembly 21, a first protrusion 321 is disposed on one side of the second stopper 32 close to the side edge of the door body 3, one end of the first protrusion 321 is fixed to the second stopper 32, and the other end extends upward along the direction perpendicular to the door body 3; the distance from the first protrusion 321 to the center of the shaft sleeve 33 is equal to the distance from the first limit block 25 to the center of the shaft sleeve 33.
The first protrusion 321 is matched with the first limit block 25 to limit the refrigerator door. When the refrigerator door rotates, the first protrusion 321 rotates around the shaft sleeve 33, and as the opening angle of the refrigerator door increases, the rotating angle of the first protrusion 321 also increases. Because the first limit block 25 is fixed on the upper hinge assembly 21, the upper hinge assembly 21 is fixed on the refrigerator body 1, the first limit block 25 does not move along with the rotation of the refrigerator door body 3, and when the first protrusion 321 rotates, an included angle between the first protrusion 321 and the first limit block 25 is continuously reduced. When the first protrusion 321 contacts with the first limiting block 25, the refrigerator door 3 can not be opened outwards any more, and the refrigerator door 3 is limited.

As shown in fig. 4 and 5, the connection module 24 connects the upper hinge assembly 21 and the bushing 33, and when the refrigerator door 3 rotates, the connection module 24 rotates inside the bushing 33.
In some embodiments, the sleeve 33 is provided with balls inside, and when the connection module 24 rotates in the sleeve 33, the connection module 24 is movably connected with the sleeve 33 through the balls. Compared with the direct contact friction between the connecting module 24 and the shaft sleeve 33, the friction can be reduced by adding the balls, and the rotation of the refrigerator door body 3 can be smoother.
In some embodiments, the self-locking block 23 is fixed to the upper hinge assembly 21 by a connecting screw 22.
As shown in fig. 4, the self-locking block 23 is fixed to the upper hinge assembly 21 by a coupling screw 22. The surface of the self-locking block 23 can be provided with a plurality of smooth sections to ensure the self-locking smoothness of the refrigerator door body 3, and the surface of the self-locking block 23 can also be provided with grains to increase the friction force to ensure the self-locking stability of the refrigerator door body 3.
In some embodiments, the upper end of the elastic member is a slope, and the height of the elastic member on the side close to the outer side of the door body 3 is greater than the height of the elastic member on the side close to the inner side of the door body 3.
When the refrigerator door is closed, the self-locking block 23 contacts with the lower side of the elastic member first, the elastic member is pressed downwards after the contact, the self-locking block 23 moves from the lower side of the elastic member to the higher side of the elastic member along with the continuous rotation of the refrigerator door body 3 in the direction close to the refrigerator body 1, and the self-locking block 23 is pressed and locked.
In some embodiments, the elastic member has a horizontal surface with the same height on the side close to the outer side of the door body 3.
In some embodiments, the distance between the self-locking groove 31 and the center of the shaft sleeve 33 is equal to the distance between the self-locking block 23 and the center of the shaft sleeve 33. When the refrigerator door is closed, the self-locking position block 23 can be just contacted with the self-locking groove 31, and self-locking of the refrigerator door 3 is realized.
In some embodiments, the second stopper 32 and the self-locking groove 31 are fixedly connected to the upper end of the door body 3 through screws. The second limiting block 32 is designed on the side of the shaft sleeve 33, is arranged below the shaft sleeve 33, is fixed by screws after the shaft sleeve 33 is arranged in the shaft sleeve 33, is foamed integrally, has firm structure and strong reliability, saves the assembly operation of a finished door body 3 at the back, and solves the problem that the traditional shaft sleeve 33 is easy to fall off.
In some embodiments, the upper end of the door body 3 is provided with a groove corresponding to the second limiting block 32 and the self-locking groove 31 in the same shape and size, and the second limiting block 32 and the self-locking groove 31 are fixed at the upper end of the door body 3 through the groove.
