[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 6 The present invention preferably provides a refrigerator with an expandable external storage unit, comprising a cabinet body 1, a connecting seat 2 at the upper end of the cabinet body 1, a first groove 3 recessed at the upper end of the connecting seat 2, and a connecting frame 4 movably disposed within the first groove 3; wherein, movable slots 5 are symmetrically provided through both sides of the connecting frame 4, and second grooves 6 are respectively recessed on the connecting seat 2 at the four corners of the first groove 3, movable seats 7 movably disposed within the second grooves 6 or protruding outward from the outside of the cabinet body 1, the movable seats 7 having an elastic pin 8 on the side near the connecting frame 4 that can elastically extend and retract relative to it, the pin of the elastic pin 8 being a round shaft, the elastic pin 8 being movably disposed within the movable slots 5, and the elastic pin 8 being able to be pressed out of the movable slots 5, and a plurality of placement frames 9 are provided at intervals on the connecting frame 4.

[0021] Furthermore, when only two elastic pins 8 located on the same side of the cabinet 1 are inserted into the movable slot 5, the connecting frame 4 can swing in a circle with the corresponding elastic pin 8 as the center; when all four elastic pins 8 are simultaneously located in the movable slot 5, the connecting frame 4 is in a locked and fixed state relative to the cabinet 1.

[0022] Specifically, the elastic pin is a relatively mature existing technology, which includes a round shaft pin and a spring. A third groove is recessed on one side of the movable seat. The round shaft pin is movably inserted into the third groove. The spring is set in the third groove and abuts against the end of the round shaft pin to realize the elastic extension and retraction displacement of the round shaft pin.

[0023] In its initial state, with the elastic pins of the four movable seats positioned within the movable slots of the connecting frame, the connecting frame is horizontally positioned at the top of the cabinet and in a retracted state. When external storage expansion is needed using the connecting frame, the user can manually press two elastic pins located on the same side of the cabinet, causing these two pins to disengage from the movable slots. This leaves only the other two elastic pins in the movable slots. At this point, the connecting frame can shift and flip relative to the elastic pins through the movable slots. By shifting the corresponding movable seats, the elastic pins in the movable slots protrude outwards onto one side of the cabinet, allowing the connecting frame to shift and move to form an externally mounted storage space on one side of the cabinet. The connecting frame is then combined with several placement frames to create an external storage space. Furthermore, the connecting frame is connected to the cabinet via movable seats and elastic pins, allowing for flexible installation and removal of the connecting frame. This facilitates users in expanding or retracting the external storage units according to their actual needs, improving the flexibility and adaptability of the refrigerator's storage space.

[0024] Furthermore, a guide groove 10 is recessed on one side of the second groove 6, and a guide rod 11 extends from one side of the movable seat 7 to engage with the guide groove 10. Two threaded holes 12 are spaced apart along the length of the guide rod 11. A through hole 13 is provided on one side of the connecting seat 2 corresponding to the threaded holes 12. A connecting screw (not shown in the figure) is inserted into the through hole 13 to engage with the threaded holes 12. Specifically, when installing the movable seat, the guide rod is inserted into the guide groove, and then the connecting screw is inserted through the through hole on one side of the connecting seat, engaging with the threaded hole on the guide rod. The connecting screw is then tightened to fix the movable seat in the appropriate position. When the position of the movable seat needs to be adjusted, the connecting screw is loosened, the movable seat is slid to the desired position, and then the connecting screw is tightened again to secure it.

[0025] Furthermore, the placement frame 9 is symmetrically provided with rotating shafts 14 on both sides. The rotating shafts 14 are rotatably mounted on the connecting frame 4. A locking member 15 is provided between the rotating shafts 14 and the connecting frame 4 to prevent their relative rotation. Thus, the placement frame can rotate relative to the connecting frame and be adjusted and locked by the locking member, so as to realize the adaptive adjustment of the placement frame when it moves and swings to the side of the cabinet, ensuring that the opening of the placement frame is always facing upwards when the cabinet is placed against the wall on either the left or right side.

[0026] Furthermore, the locking member 15 includes a spring 16 and a locking element 17. One side of the rotating shaft 14 has a recessed limiting groove 18 along its length. The locking element 17 is movably sleeved on the rotating shaft 14, and a flange that can cooperate with the limiting groove 18 is provided on the inner side of the locking element 17. The flange cooperates with the limiting groove 18 so that the locking element 17 can only be displaced along the axial direction of the rotating shaft 14. A limiting plate 20 is fixedly provided on the rotating shaft 14. The spring 16 is sleeved on the rotating shaft 14 and abuts between the locking element 17 and the limiting plate 20. One side of the connecting frame 4 has a recessed circular groove 21 that can fit into the locking element 17. A plurality of slots 22 are evenly distributed along the circumference of the inner side of the circular groove 21. The locking element 17 has evenly distributed protruding teeth 23 that can engage with the slots 22. The spring 16 keeps the teeth 23 and the slots 22 engaged. Furthermore, by engaging the teeth and slots and maintaining the engagement with the spring, the rotation of the shaft relative to the connecting frame is locked and fixed.

[0027] Furthermore, a limiting nut 24 is threaded onto the rotating shaft 14. Specifically, the limiting nut threaded onto the rotating shaft can restrict the position of the rotating shaft on the connecting frame, preventing axial displacement of the rotating shaft during use, thereby ensuring the stability of the rotational connection between the placement frame and the connecting frame, and further improving the structural reliability of the external storage unit of the refrigerator.

[0028] Furthermore, a hook is provided on one side of the placement frame 9. This provides users with an additional hanging storage method, making it convenient for users to hang small items such as shopping bags and tableware, further enriching the storage function of the external storage unit of the refrigerator and improving the utilization rate and convenience of storage space.
