[0022] like Figure 1-5 As shown, a multi-functional shelf with adjustable shelf height includes two pairs of bases 1 on the left and right. A vertical rod 2 is fixedly connected to the top of the base 1. A sliding sleeve 3 slides on the vertical rod 2. A placement plate 4 is fixedly connected between the opposite side walls of the sliding sleeve 3 for placing various items. A horizontal bar 20 is fixedly connected between the bases 1. The horizontal bar 20 can improve the overall structural stability of the shelf and prevent the whole structure from shaking when placing heavy items.

[0023] The positioning component is located on the sliding sleeve 3, including a movable plate 5 hinged to the outer wall of the sliding sleeve 3. A pin 6 is fixedly connected to the outer wall of the movable plate 5. A spring 7 is fixedly connected between the movable plate 5 and the opposite side wall of the sliding sleeve 3. The sliding sleeve 3 is provided with a through hole 8. A guide strip 9 is fixedly connected to the outer wall of the vertical rod 2. The sliding sleeve 3 is slidably connected to the guide strip 9. The guide strip 9 is provided with linearly arranged side grooves 10. The diameters of the through hole 8 and the side grooves 10 are both larger than the diameter of the pin 6. The pin 6 passes through the through hole 8 and is inserted into the side groove 10.

[0024] Fixed blocks 11 are fixedly connected to both the front and rear sides of the sliding sleeve 3. Adjusting sleeves 12 are threadedly connected to the fixed blocks 11. The outer wall of the movable plate 5 is connected to a sliding rod 13 through a universal joint. The sliding rod 13 is symmetrically distributed front and back and is T-shaped. Its end moves through one end of the adjusting sleeve 12. The outer wall of the sliding sleeve 3 is fixedly connected to guide blocks 14 symmetrically distributed front and back. The sliding rod 13 passes through the guide block 14 and is slidably connected to it. The guide block 14 can ensure that the adjustment process of the sliding rod 13 is smooth and prevent the sliding rod 13 from deviating or getting stuck when moving.

[0025] When the height of the placement plate 4 needs to be adjusted, rotate the adjusting sleeve 12 to allow the sliding rod 13 to slide. Then, manually press the movable plate 5. The spring 7 deforms, and the insert 6 can leave the side groove 10 and the through hole 8. Then, slide the sliding sleeve 3 along the guide strip 9 on the vertical rod 2 to adjust the placement plate 4 to the appropriate height. After that, release the movable plate 5. The sliding rod 13 returns to its original position under the elastic force of the spring 7. The movable plate 5 drives the insert 6 to pass through the through hole 8 of the sliding sleeve 3 and re-insert into the side groove 10 corresponding to the guide strip 9 to complete the height fixation. Then, screw the adjusting sleeve 12 so that its inner wall is tightly against the end of the sliding rod 13 to prevent the movable plate 5 from being squeezed and misoperated. This adjustment method does not require disassembling the bolts, is convenient and efficient, and can meet the needs of frequent height adjustments.

[0026] Mounting blocks 15 are fixedly connected to the top and bottom of the placement plate 4. Reinforcing rods 16 are bolted to the mounting blocks 15. Telescopic rods 17 slide at the ends of the reinforcing rods 16. The telescopic rods 17 are provided with evenly distributed positioning grooves 18. The reinforcing rods 16 are provided with positioning holes 19 corresponding to the positioning grooves 18. Depending on the span of the shelf, the telescopic rods 17 can be pulled to extend the telescopic rods 17 from the reinforcing rods 16 to a suitable length. Then, the two are fixed by bolts passing through the positioning holes 19 of the reinforcing rods 16 and the positioning grooves 18 of the telescopic rods 17. The cooperation of the reinforcing rods 16 and the telescopic rods 17 can enhance the load-bearing capacity of the placement plate 4 and prevent the placement plate 4 from shaking or deforming due to uneven force when heavy objects are placed.

[0027] The bottom of the base 1 is provided with a bottom groove 21 and a thread inside. The bottom groove 21 facilitates the spiral connection of self-locking casters or adjustable support legs. When the self-locking casters are connected, the shelf can be moved flexibly and is convenient to switch between different scenarios. When the adjustable support legs are connected, it can adapt to uneven ground and ensure that the shelf is placed stably. The overall structure improves the versatility and safety of the shelf and meets the needs of diverse storage scenarios.

[0028] The working principle of this utility model is as follows: As needed, self-locking casters or adjustable support legs are connected to the bottom groove 21 of the base 1. Items are placed on the placement plate 4. When it is necessary to adjust the height of the placement plate 4, the movable plate 5 is manually pressed so that the insert 6 can leave the side groove 10 and the through hole 8. Then, the sliding sleeve 3 is slid along the guide strip 9 on the vertical rod 2. After sliding the sliding sleeve 3 to the appropriate height, the movable plate 5 is released. The sliding rod 13 is reset under the elastic force of the spring 7. The movable plate 5 drives the insert 6 to pass through the through hole 8 of the sliding sleeve 3 and re-insert into the side groove 10 corresponding to the guide strip 9 to complete the height fixation. Then, the adjusting sleeve 12 is screwed so that its inner wall is tightly attached to the end of the sliding rod 13 to prevent the movable plate 5 from being squeezed and misoperated.

[0029] If heavy items are placed on the plate, a reinforcing rod 16 can be installed on the plate 4 using the mounting block 15, the extension length of the telescopic rod 17 can be adjusted, and it can be fixed with bolts through the positioning groove 18 and the positioning hole 19 to enhance the load-bearing capacity of the plate 4.
