[0026] Refer to the attached Figure 1 The embodiment of the invention provides a height-adjustable refrigerator shelf, including a shelf body 1, which is made of aluminum alloy to ensure its lightness and firmness. The shelf body 1 is provided with a plurality of water outlet grooves 15, and the design of the water outlet grooves 15 is helpful for rapid drainage during cleaning or use, avoiding water accumulation on the shelf body 1, thereby enhancing the convenience and hygiene of use.

[0027] Refer to the attached Figure 1 and Figure 2 , a bidirectional screw 2 is rotatably installed inside both sides of the shelf body 1, and the bidirectional screw 2 is made of stainless steel. A first bevel gear 3 is fixedly installed on the bidirectional screw 2. A connecting rod 4 is rotatably installed in the middle position of both ends of the shelf body 1, and the bidirectional screw 2 and the connecting rod 4 are vertically arranged. A second bevel gear 5 meshing with the first bevel gear 3 is fixedly installed on the connecting rod 4. A handwheel 6 is fixedly installed on the outer end of the connecting rod 4. The outer wall of the handwheel 6 is processed with anti-slip patterns. The anti-slip patterns increase the friction between the handwheel 6 and the user's palm, which is more conducive to the user turning the handwheel 6. The combination of the bidirectional screw 2, the first bevel gear 3, the second bevel gear 5, the connecting rod 4 and the handwheel 6 forms an efficient transmission system. By turning the handwheel 6, the connecting rod 4 and the first bevel gear 3 and the second bevel gear 5 can be driven to rotate, thereby driving the bidirectional screw 2 to rotate.

[0028] Refer to the attached Figure 1 , Figure 2 and Figure 5, moving rods 7 are threadedly connected on both sides of the bidirectional screw 2, and the width of the moving rod 7 is equal to the internal width of the two ends of the shelf body 1, thereby realizing the limitation of the moving rod 7, so that the moving rod 7 can move along the length direction of the shelf body 1 during the rotation of the bidirectional screw 2, and the moving rod 7 is made of aluminum alloy material, and a protrusion 8 is fixedly installed on the outer end of the moving rod 7; brackets 9 are provided on both sides of the outside of the shelf body 1, and a plurality of grooves 10 matched with the protrusion 8 are evenly spaced on both sides of the inner wall of the bracket 9, and the protrusion 8 and the groove 10 are both cylindrical structures.

[0029] The moving rod 7 moves in the horizontal direction driven by the bidirectional screw 2, and the protrusion 8 at its outer end is adapted to the groove 10 on the inner wall of the bracket 9 to fix the position of the moving rod 7. Through the cooperation of the moving rod 7 and the protrusion 8, the height of the shelf body 1 can be accurately adjusted and fixed, thereby ensuring the stability and safety of the shelf body 1.

[0030] Refer to the attached Figure 3 and Figure 4 A plurality of plug-in slots 11 are provided on the shelf body 1 at equal intervals along the width direction. A cross bar 12 is provided on both sides of the exterior of the shelf body 1. The cross bar 12 is fixedly provided with plug-in rods 13 having the same number as the plug-in slots 11. Cards 14 are fixedly provided at both ends of the cross bar 12. The cards 14 are adapted to the moving rod 7. The cards 14 are in a "["-shaped structure. The cards 14 are used to fix the position of the cross bar 12 to prevent it from shaking. By providing the plug-in slots 11, the cross bar 12 and the plug-in rod 13, and controlling the length of the plug-in rod 13 inserted into the plug-in slots 11, the overall length of the shelf body 1 can be adjusted to adapt to refrigerators of different specifications.
