[0021] Example 1, see Figure 1-6 As shown, a storage rack includes a vertical pole assembly 2 with a shelf 4, an upper pole assembly 1 with a rotation and telescopic adjustment is provided on the top of the vertical pole assembly 2, and a lower pole assembly 3 is provided on the bottom of the vertical pole assembly 2.

[0022] The lower rod assembly 3 includes a bottom rod 5, a spring 31 and a slide bar 32. A mounting groove 51 is provided in the bottom rod 5 along the height direction. The mounting groove 51 is provided with an opening on the top surface of the bottom rod 5. The bottom of the vertical rod assembly 2 is inserted into the mounting groove 51 through the opening. A limiting slide groove 52 is provided in the bottom rod 5 along the height direction. The slide bar 32 is horizontally arranged at the bottom of the vertical rod assembly 2. The end of the slide bar 32 extends into the limiting slide groove 52. The spring 31 is placed in the mounting groove 51. The top of the spring 31 abuts against the bottom surface of the vertical rod assembly 2. The elastic force of the spring 31 causes the vertical rod assembly 2 to move upward until the slide bar 32 abuts against the top of the limiting slide groove 52. Preferably, a fixing cylinder 53 is provided in the mounting groove 51. The bottom of the spring 31 is placed in the fixing cylinder 53. The bottom of the spring 31 abuts against the bottom surface of the fixing cylinder 53.

[0023] The upper rod assembly 1 includes a top rod 11, a bolt 6 and an expansion sleeve 7. A telescopic groove 20 is provided at the top of the vertical rod assembly 2 along the height direction. The bottom of the top rod 11 is inserted into the telescopic groove 20. The bolt 6 and the expansion sleeve 7 are arranged in the telescopic groove 20. The bolt 6 is fixed at the bottom of the top rod 11, and the external thread of the bolt 6 and the internal thread of the expansion sleeve 7 are threadedly connected.

[0024] Among them, the bolt 6 includes a fixed section 61, a truncated cone section 62 and a limiting section 63 from top to bottom, the fixed section 61 is connected and fixed to the bottom of the top rod 11, the diameter of the truncated cone section 62 gradually increases from low to high, and the outer circumference of the truncated cone section 62 is provided with the external thread, and the expansion sleeve 7 includes a conical hole section 71 and a limiting hole section 72 from top to bottom, the inner circumference of the conical hole section 71 is provided with the internal thread, the diameter of the conical hole section 71 gradually increases from low to high, and the diameter of the limiting hole section 72 is smaller than the minimum diameter of the conical hole section 71. The expansion sleeve 7 has a diameter of 200 mm and a plurality of slots 73 in the height direction along its outer circumference. The openings of the slots 73 are arranged at the bottom surface of the expansion sleeve 7. The bolt 6 is inserted into the expansion sleeve 7. The truncated cone section 62 cooperates with the conical hole section 71. The limiting section 63 passes through the limiting hole section 72 to the bottom of the expansion sleeve 7. When the expansion sleeve 7 is placed in the expansion slot 20, the side wall of the expansion slot 20 reduces the diameter of the limiting hole section 72 to be smaller than the diameter of the limiting section 63. The bolt 6 drives the expansion sleeve 7 to move in the expansion slot 20 through the limiting section 63.

[0025] The vertical pole assembly 2 includes multiple long rods 21 and at least one shelf 4. The long rods 21 are connected and fixed by connecting sleeves 22. A fixing sleeve 41 is provided on one side of the shelf 4. The fixing sleeve 41 is inserted on any long rod 21. The outer side of the fixing sleeve 41 is provided with a screw hole 42 and a fixing screw (not shown in the figure). The fixing screw is threadedly connected with the screw hole 42. The inner end of the fixing screw passes through the screw hole 42 and abuts against the long rod 21 to limit the shelf 4 on the long rod 21. The long rod 21 is hollow to form the telescopic slot 20.

[0026] Slots 23 are provided at the upper and lower ends of the connecting sleeve 22, and a tightening groove 24 connected to the slot 23 is provided on the outer wall of the connecting sleeve 22 along the height direction.

The two fixed ears 25 are connected by a tightening screw (not shown in the figure), and the end of the long rod 21 is inserted into the slot 23. The tightening screw brings the two fixed ears 25 together so that the slot 23 clamps the long rod 21.

[0027] During installation, according to the reserved installation height between the support table and the cabinet or ceiling, after the shelf is assembled, the overall height of the shelf is less than the reserved installation height. First, adjust the upper rod assembly 1, pull out the top rod 11 upward, that is, the top rod 11 drives the bolt 6 and the expansion sleeve 7 to move in the telescopic slot 20, so that the overall height of the shelf is slightly greater than the reserved installation height, rotate the top rod 11, the top rod 11 drives the bolt 6 to rotate, and the bolt 6 causes the expansion sleeve 7 to collide outward, that is, the expansion sleeve 7 is fixed in the telescopic slot 20. Then the vertical rod assembly 2 is pressed down as a whole, that is, the vertical rod assembly 2 compresses the spring 31 and drives the slide bar 32 to move in the limit slide slot 52, at this time, the overall height of the shelf is less than the reserved installation height. The shelf is placed between the support table or ceiling and the cabinet, and the vertical rod assembly 2 is loosened. The spring 31 pushes the vertical rod assembly 2 upward, that is, the upper rod assembly 1 moves up with the vertical rod assembly 2 and contacts the bottom surface of the cabinet or the ceiling. On the contrary, the vertical rod assembly 2 is pressed down as a whole, and the shelf can be taken out.

[0028] During this process, the extension length of the upper rod assembly 1 can be appropriately adjusted according to the material of the cabinet or ceiling, that is, the overall height of the shelf exceeds the reserved installation height, and then the elastic force of the spring 31 is adjusted within the range of the limiting slide groove 52.
