Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present invention.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] Please also read Figure 1 and Figure 2 The embodiment of the present invention provides a refrigerator with a self-locking function, including a cabinet 1, a cabinet door 2, a locking assembly 3 and a pressing piece 4, wherein a chamber is provided in the cabinet 1 for storing articles; the cabinet door 2 is rotatably connected to the cabinet 1 for opening and closing the chamber; the locking assembly 3 is engaged with the pressing piece 4; one of the locking assembly 3 and the pressing piece 4 is provided on the cabinet 1, and the other is provided on the cabinet door 2; with such an arrangement, when the cabinet door 2 is closed and abuts against the cabinet 1, the locking assembly 3 and the pressing piece 4 are engaged with each other to ensure the sealing effect of the cabinet 1 and the cabinet door 2, and even after passing through a bumpy road section, the cabinet door 2 of the refrigerator will not be separated from the cabinet 1, thereby avoiding collision between the cabinet door 2 and the cabinet 1 and ensuring the quality of the refrigerator.

[0039] The refrigerator of this embodiment further comprises a shelf assembly 5, which is arranged in the cavity. The shelf assembly 5 is detachably connected to the box body 1 and is used for supporting items in the cavity.

[0040] For details, please refer to Figure 3 , Figure 3 FIG. 1 is an exploded perspective structural diagram of the locking assembly 3 in this embodiment. The locking assembly 3 includes a fixing seat 31 and a supporting member 32. The fixing seat 31 includes an integrally formed body 311 and a clamping portion 312. The supporting member 32 includes a locking portion 321 and a limiting portion 322. The limiting portion 322 is rotatably connected to the clamping portion 312. Please refer to FIG. Figures 4 to 7 , Figure 4 and Figure 6 Schematic diagram of the embodiment when the pressing member 4 and the supporting member 32 are not engaged and connected. Figure 5 and Figure 7This is a schematic diagram of the clamping member 4 and the support member 32 when they are snap-connected in this embodiment. The clamping member 4 includes an integrally formed first clamping wall 41 and a second clamping wall 42, which are snap-connected to the locking assembly 3; the clamping member 4 also includes a locking portion 321, which is arranged on the inner side of the first clamping wall 41. When the locking portion 43 is snap-connected with the locking portion 321, the locking portion 43 is tangent to the locking portion 321.

[0041] Preferably, in this embodiment, the locking portion 321 is configured as a cylinder, or a cylinder that is narrow at both ends and wide in the middle, so as to abut against the inner sides of the first clamping wall 41 and the second clamping wall 42. During the process of the locking portion 43 being engaged and connected with the locking portion 312, the clamping member 4 pushes the locking portion 321 to rotate; the locking portion 312 is also configured as a cylinder to ensure that the support member 32 can rotate relative to the fixed seat 31.

[0042] More specifically, Figure 2 As shown, in this embodiment, the fixing seat 31 is fixedly connected to the box body 1, and the pressing member 4 is fixedly connected to the corresponding position of the box door 2. During the opening and closing process of the box door 2 relative to the box body 1, the pressing member 4 drives the supporting member 32 to rotate relative to the fixing seat 31. Figure 8 As shown, the locking portion 43 includes a first locking surface 431 and a second locking surface 432, and a point A is provided on the locking portion 43. The first locking surface 431 and the second locking surface 432 have a smooth transition. The left side of point A is the first locking surface 431, and the right side of point A is the second locking surface 432. The locking portion 321 includes a first locking surface 3211 and a second locking surface 3212. A point B is provided on the locking portion 321. The first locking surface 3211 and the second locking surface 3212 have a smooth transition. The left side of point B is the second locking surface 3212, and the right side of point B is the first locking surface 3211. Point A and point B are located on the same horizontal plane. Figure 8The cross section of the middle locking portion 321 is configured as a circle, and the locking surface of the locking portion 43 is configured as an arc. When the pressing member 4 moves in the direction of arrow C in the figure, the first locking surface 431 abuts against the first locking surface 3211, and the first locking surface 431 interferes with the first locking surface 3211, pushing the support member 32 to rotate in the direction of D, and the pressing member 4 and the support member 32 are relatively deformed. The first pressing wall 41 gradually passes through point B. After the first locking surface 431 completely passes through point B, it fits with the second locking surface 3212 until point A coincides with point B. At this time, the first locking surface 3211 fits with the second locking surface 432, and the second locking surface 3212 fits with the first locking surface 431 to form a snap connection; that is, the box door 2 forms a snap connection with the box body 1, the chamber is closed, and the first pressing wall 41 and the second pressing wall 4 are snapped together. 2 are perpendicular to each other, and the inner sides of the first pressing wall 41 and the second pressing wall 42 are both in contact with the support member 32. Under the joint action of the locking assembly 3 and the pressing member 4, the sealing effect of the box body 1 and the door 2 is guaranteed; when the refrigerator with the above-mentioned locking assembly 3 and the pressing member 4 passes through a bumpy section, the first locking surface 431 is clamped by the first locking surface 3211, and the first locking surface 431 cannot move to the right side of point B, the pressing member 4 and the support member 32 cannot disconnect the clamping connection, and the refrigerator door 2 will not be separated from the box body 1; only when the user pulls the door 2, the pressing member 4 and the support member 32 are relatively deformed, the support member 32 is pulled by the pressing member 4 and rotates clockwise, and after the first locking surface 431 moves to the right side of point B, the pressing member 4 and the support member 32 disconnect the clamping connection, the door 2 is disconnected from the box body 1, and the chamber is opened.

[0043] It can be understood that, during the engagement between the clamping member 4 and the support member 32, the first locking surface 3211 hinders the horizontal leftward movement of the first locking surface 431. When part of the first locking surface 431 moves to the left side of point B, the support member 32 rotates counterclockwise, and the first locking surface 3211 and the second locking surface 3212 play a guiding role, so that the clamping member 4 abuts against the support member 32, and point A coincides with point B, that is, the locking portion 43 is tangent to the locking portion 321; similarly, during the disconnection between the clamping member 4 and the support member 32, the first locking surface 3211 hinders the horizontal rightward movement of the first locking surface 431. When part of the first locking surface 431 moves to the right side of point B, the support member 32 rotates clockwise, and the first locking surface 3211 and the second locking surface 3212 play a guiding role, so that the clamping member 4 and the support member 32 are disconnected.

[0044] In summary, the present invention provides a refrigerator with a self-locking function, comprising a cabinet 1, a cabinet door 2, a locking assembly 3 and a pressing piece 4, wherein a chamber is provided in the cabinet 1 for storing articles; the cabinet door 2 is rotatably connected to the cabinet 1 for opening and closing the chamber; the locking assembly 3 is engaged with the pressing piece 4; one of the locking assembly 3 and the pressing piece 4 is provided on the cabinet 1, and the other is provided on the cabinet door 2; with such an arrangement, when the cabinet door 2 is closed and abuts against the cabinet 1, the locking assembly 3 and the pressing piece 4 are engaged with each other to ensure the sealing effect of the cabinet 1 and the cabinet door 2, and even after passing through a bumpy road section, the cabinet door 2 of the refrigerator will not be separated from the cabinet 1, thereby avoiding collision between the cabinet door 2 and the cabinet 1 and ensuring the quality of the refrigerator.
