[0026] Example 1 Reference Figure 1-4 The present invention provides a refrigerator partition balancing structure, comprising a refrigeration unit 100, a shelf unit 200, an isolation unit 400 and a support unit 300, characterized in that: The refrigeration unit 100 includes a refrigeration layer 101 , and a back plate 102 is fixedly connected to the inner wall surface of the refrigeration layer 101 ; The shelf unit 200 is provided on the inner wall surface of the refrigeration layer 101. The shelf unit 200 includes a partition frame 201. The partition frame 201 is hollow and is used to support the partitions and drawers. The support unit 300 is disposed inside the partition frame 201 and includes a bidirectional screw 301 and a support plate 305 for adjusting the level of the partition frame 201. The isolation unit 400 is disposed at the front side of the partition frame 201 . The isolation unit 400 includes an isolation plug 402 for isolating the interior of the partition frame 201 .

[0027] During use, the drawer partitions are supported by the partition unit 200, and the partition frame 201 can be opened through the isolation unit 400, so that the support unit 300 can raise and lower the height of one end of the partition frame 201, and the supporting part of the partition frame 201 can be adjusted horizontally, so that the left and right fruit and vegetable box drawers of the partition frame 201 are consistent in level, thereby improving the appearance and the use effect. At the same time, the interior of the partition frame 201 can be waterproofed and isolated to avoid rust that affects the normal use of the support unit 300.

[0028] Example 2 Reference Figure 2-8 , which is the second embodiment of the present invention. It is different from the previous embodiment in that both sides of the partition frame 201 are fixedly connected with sliding frames 202, and the interior of the sliding frames 202 are slidably connected with mounting rods 203, and the two sets of mounting rods 203 are fixedly connected to the inner wall surface of the cold storage layer 101, and both sides of the partition frame 201 are fixedly connected with side panels 204, and the lower side surfaces of the side panels 204 are tightly fitted with the inner wall surface of the cold storage layer 101, and one side of the back panel 102 is fixedly connected with a snap buckle 205, and the snap buckle 205 is slidably connected to the surface of the partition frame 201, and a through slot 206 is opened on one side of the partition frame 201 for connecting the inner and outer spaces of the partition frame 201.

[0029] Furthermore, the surface of the bidirectional screw 301 is threadedly connected to two groups of threaded cylinders 302, and the surfaces of the threaded cylinders 302 are fixedly connected to movable plates 303, the upper and lower sides of the two groups of movable plates 303 are rotatably connected to rotating plates 304, and the rotating plates 304 are rotatably connected to support plates 305, the upper surface of the top support plate 305 is tightly fitted with the inner wall surface of the partition frame 201, and the lower surface of the bottom support plate 305 is fixedly connected to the cold storage layer 101. By twisting the bidirectional screw 301 to rotate, the distance between the two groups of support plates 305 can be adjusted, thereby pushing one end of the partition frame 201 to rise and fall on the surface of the cold storage layer 101.

[0030] Furthermore, the surface of the bidirectional screw 301 is rotationally connected to the limit block 306, and the surface of the limit block 306 is slidingly connected to two sets of limit frames 307. The lower surfaces of the two sets of limit frames 307 are fixedly connected to the cold storage layer 101, and have a limiting effect, so that the structure of the bidirectional screw 301, the threaded barrel 302 and the support plate 305 is stable.

[0031] Furthermore, the rust-proof unit 308 includes two groups of rotating grooves 3085 opened on the surfaces of the two groups of threaded barrels 302, and the interiors of the rotating grooves 3085 are rotatably connected to rotating rings 3081, and the two groups of adjacent rotating rings 3081 are fixedly connected to rubber sleeves 3082, and the other ends of the rubber sleeves 3082 are fixedly connected to the center circle block 3084, and the two groups of opposite rotating rings 3081 are fixedly connected to another rubber sleeve 3082, and the other ends of the other rubber sleeves 3082 are fixedly connected to the side circular plates 3083, so that the rubber sleeves 3082 provide waterproof protection for the threaded parts of the bidirectional screw 301 to prevent the threaded barrel 302 and the bidirectional screw 301 from rusting and blocking.

[0032] Furthermore, the inner diameters of both ends of each set of rubber sleeves 3082 are smaller than the inner diameter of the middle portion of the rubber sleeve 3082 , and each set of rubber sleeves 3082 is made of rubber material to prevent the rubber sleeves 3082 from contacting the bidirectional screw 301 .

[0033] Furthermore, a sliding groove is provided at one end of the bidirectional screw 301 away from the limit frame 307, and a square rod 309 is slidably connected inside the sliding groove, and a torsion block 310 is fixedly connected to the other end of the square rod 309. The bidirectional screw 301 can accommodate the square rod 309, and twisting the torsion block 310 causes the square rod 309 to drive the bidirectional screw 301 to rotate.

[0034] Among them, the surface of the isolation plug 402 is movably connected to the inner wall surface of the through groove 206, the upper side of the isolation plug 402 is fixedly connected with a connecting strip 403, and the connecting strip 403 is fixedly connected to the partition frame 201, and the lower side of the isolation plug 402 is fixedly connected with a pull strip 404. Pulling the pull strip 404 can drive the isolation plug 402 to slide out from the inside of the through groove 206, opening the through groove 206.

[0035] Furthermore, the pull strip 404 is T-shaped for easy hand-held pulling, and the isolation plug 402 is made of rubber material, so that the isolation plug 402 will not move outward at will when it is inside the through slot 206. The interior of the isolation plug 402 is fixedly connected to a magnetic block 405, and the surface of the magnetic block 405 is movably connected to the surface of one side of the twist block 310. The twist block 310 is made of a magnetically attractive metal material. When the isolation plug 402 moves to open the through slot 206, the magnetic block 405 can use magnetism to cause the twist block 310 to drive the square rod 309 to slide out from the inside of the bidirectional screw 301.

[0036] Example 3 Reference Figure 1-6 , which is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a method for using a refrigerator partition balancing structure. The method is applicable to the refrigerator partition balancing structure described in any one of the above embodiments 1-2. The method includes the following steps: During use, the pull bar 404 is pulled to drive the isolation plug 402 to slide out from the through slot 206, and the magnetic block 405 fixedly connected to the isolation plug 402 drives the twist block 310 to move out from the inside of the partition frame 201, so that the square rod 309 fixedly connected to the twist block 310 slides inside the bidirectional screw 301, and then the twist block 310 is twisted to drive the square rod 309 to rotate, and the bidirectional screw 301 slidably connected to the square rod 309 starts to rotate, so that the two sets of threaded barrels 302 threadedly connected to the bidirectional screw 301 move in opposite directions, thereby pushing the movable plate 303 fixedly connected to the threaded barrel 302 to push The rotating plate 304 rotates, causing the support plate 305 rotatably connected to the rotating plate 304 to move relatively, and driving the limit block 306 to slide up and down inside the limit frame 307. At the same time, the limit block 306 rotatably connected to the bidirectional screw 301 slides within the limit frame 307 to adjust the distance between the two sets of support plates 305, thereby causing the top support plate 305 to drive one end of the partition frame 201 to rise and fall, and the supporting part of the partition frame 201 to be horizontally adjusted, so that the left and right fruit and vegetable box drawers of the partition frame 201 are aligned in level, thereby improving the appearance and the use effect. During the rotation of the bidirectional screw 301, the side circular plate 3083 and the center circular block 3084 fixedly connected to the bidirectional screw 301 rotate synchronously, causing the rubber sleeve 3082 fixedly connected to the side circular plate 3083 and the center circular block 3084 to rotate synchronously, thereby causing the rotating ring 3081 fixedly connected to the rubber sleeve 3082 to rotate inside the rotating groove 3085. This can waterproof the threads of the bidirectional screw 301 and the threaded barrel 302, prevent rust and blockage during long-term use, and extend the service life; Finally, press the twist block 310 into the interior of the partition frame 201, and the square rod 309 fixedly connected to the twist block 310 slides into the interior of the bidirectional screw 301, and then place the isolation plug 402 inside the through groove 206, so that the magnetic block 405 fits with the surface of the twist block 310, which can isolate the inside and outside of the partition frame 201.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
