[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] like Figures 1 to 9 The refrigerator's left and right door switching mechanism, as shown, includes a cabinet body 1, a door body 2, and a rotating connection mechanism that can rotatably connect the door body 2 to the cabinet body 1. The rotating connection mechanism includes a rotating shaft structure 3 located on the left and right sides of the cabinet body 1 or the left and right sides of the door body 2, and a mounting base 4 correspondingly located on the other. The rotating shaft structure 3 includes a connecting seat 31 and a shaft head 32 connected to the connecting seat 31. The mounting base 4 is provided with a protrusion 411, and the protrusion 411 is provided with a first... The first opening groove 412 is provided, and the front side of the protrusion 411 is also provided with a first clearance opening 413 for the shaft head 32 to slide into or out of the first opening groove 412. The mounting base 4 is also connected with a limiting post 414, which is located in the first opening groove 412. The shaft head 32 is provided with a second opening groove 321 for accommodating the limiting post 414, and the rear side of the shaft head 32 is also provided with a second clearance opening 322 for the limiting post 414 to slide into or out of the second opening groove 321. When the door 2 is opened, the shaft head 32 on the opening side of the door 2 exits the second opening groove 321, and the shaft head 32 on the other side serves as a pivot.

[0035] This invention utilizes the coordinated design of the first clearance opening 413 and the second clearance opening 322, allowing the shaft head 32 to slide directly into or out of the first opening slot 412 along the first clearance opening 413. This enables the installation, disassembly, or switching of the left and right opening directions of the door without tools. During operation, only the door body 2 needs to be pushed horizontally or the installation direction adjusted, significantly improving user convenience. The limiting post 414 is embedded in the second opening slot 321 of the shaft head 32. When the door body 2 is opened to a certain angle, the first clearance opening 413 and the second clearance opening 322 are misaligned, and the protrusion 411 and the limiting post 414 can physically engage the shaft head 32, forming a double limiting mechanism. This prevents the shaft head 32 from accidentally dislodging due to vibration or external force when the door is opened, greatly improving the stability and safety of the door body 2 connection. Opening one side of the latch 52 and pulling that side of the door body 2 causes the shaft head 32 on that side to exit the second opening slot 321, while the shaft head 32 on the other side serves as a pivot.

[0036] Furthermore, both the protrusion 411 and the shaft head 32 are arc-shaped, which facilitates the rotation of the shaft head 32 within the first opening groove 412.

[0037] In one embodiment, the shaft head 32 and the connecting seat 31 are an integral structure. The connecting seat 31 is also provided with two plug-in parts 300 that can be plugged into the door frame. The plug-in parts 300 can be interference-fitted with the plug interface of the door frame. Of course, the plug-in parts 300 can also be connected to the door frame by glue or threaded fasteners.

[0038] In one embodiment, the left and right sides of the door 2 are also provided with limiting structures 5 that prevent the shaft head 32 from exiting the first opening slot 412 when the door 2 is closed. The limiting structures 5 lock the door 2 and the housing 1 when the door 2 is closed, thereby preventing the shaft head 32 from accidentally exiting the first opening slot 412 and eliminating the risk of the door 2 accidentally disengaging due to vibration, collision or misoperation.

[0039] Specifically, the limiting structure 5 includes a latching structure, which includes latch seats 51 connected to the left and right sides of the housing 1 and latches 52 correspondingly located on the left and right sides of the door 2 and capable of engaging with the latch seats 51. The latches 52 are rotatably connected to the door 2, and a return spring 520 is provided between the latches 52 and the door 2 to push the latches 52 towards the latch seats 51. The latching structure can also be used as a door lock and handle. Opening one side of the latches 52 and pulling that side of the door 2 causes the shaft head 32 on that side to exit the second opening slot 321, while the shaft head 32 on the other side serves as a pivot.

[0040] Furthermore, the side of the latch 51 is provided with a latch groove 510 for the latch 52 to engage. The left and right door opening switching mechanism also includes a locking block 53 that can be inserted into the latch groove 510 to restrict the latch 52 from engaging with the latch 51. When the locking block 53 is inserted into the latch groove 510, the latch 52 cannot engage, thus restricting the door 2 from closing. This allows a gap to be left between the refrigerator body 1 and the door 2 for air circulation between the inside and outside of the refrigerator, preventing poor air quality inside the refrigerator when it is not powered on.

[0041] Furthermore, the locking block 53 is also provided with a protrusion 530 for easy removal.

[0042] In one embodiment, the connecting seat 31 is provided with a guide groove 33 for guiding the limiting post 414 into the second opening groove 321. During the installation of the door body 2, the limiting post 414 is automatically guided into the second opening groove 321, eliminating manual alignment errors. The end of the guide groove 33 forms a continuous and smooth transition with the entrance of the second opening groove 321.

[0043] In one embodiment, the connecting seat 31 includes an upper connecting seat 311 located on the upper part of the left and right sides of the door body 2 and a lower connecting seat 312 located on the lower part of the left and right sides of the door body 2. The mounting seat 4 includes an upper mounting seat 42 located on the upper part of the left and right sides of the housing 1 and a lower mounting seat 43 located on the lower part of the left and right sides of the housing 1. An mounting area 44 for mounting the door body 2 is provided between the upper mounting seat 42 and the lower mounting seat 43. The position of the upper mounting seat 42 corresponds to the upper connecting seat 311, and the position of the lower mounting seat 43 corresponds to the lower connecting seat 312. The structure of the lower mounting seat 43 is the same as or similar to the structure of the upper mounting seat 42.

[0044] Furthermore, the upper mounting base 42 includes a base plate 421 and an end plate 422 connected to the base plate 421. The protrusion 411 is disposed on the base plate 421, and the limiting post 414 is disposed on the end plate 422. The base plate 421 has a through hole 423 for the limiting post 414 to be inserted into the first opening slot 412. The protrusion 411 and the base plate 421 are an integral structure. The limiting post 414 and the end plate 422 are an integral structure.

[0045] Furthermore, the upper mounting base 42 is provided with a plurality of mounting holes 424 penetrating the base plate 421 and the end plate 422. The upper mounting base 42 can be fixedly connected to the housing 1 by threaded fasteners.
