[0011] The beneficial effects of this utility model are as follows:
[0012] 1. The present invention provides an anti-tipping metal shelf structure, which uses a hexagonal head to drive a bidirectional lead screw to rotate. Based on the threaded connection between the thread and the movable block, the movable block is controlled to move axially along the bidirectional lead screw. The moving movable block drives a connecting rod to control the extension and retraction of the telescopic bar. When the shelf is in use, the telescopic bar extends to increase the bottom area of the shelf, thereby preventing tipping. The bidirectional lead screw also has a self-locking function to prevent the telescopic bar from retracting. When the shelf is not in use, the telescopic bar retracts to reduce the floor space occupied by the shelf.
[0013] 2. The anti-tipping metal shelf structure provided in this embodiment of the utility model can improve the fixing effect of the telescopic bar and the adjusting block by setting the limiting bar and the slot, thereby further improving the stability and anti-tipping ability of the shelf. At the same time, it can also provide a limiting effect and improve the stability of the adjusting block and the telescopic bar when they are extended.
[0014] 3. The anti-tipping metal shelf structure provided in this utility model embodiment can effectively prevent metal fatigue caused by the axial torsion of the moving block by the set limiting groove, thereby improving the structural life of the bidirectional lead screw, the moving block and the connecting rod, and thus improving the overall life of the adjustment component.
[0015] 4. The anti-tipping metal shelf structure provided in this embodiment of the utility model uses a set support rod and movable fixing bolts to support and fix the telescopic bar, reducing the load-bearing capacity of the telescopic bar, thereby effectively improving the load-bearing capacity of the telescopic bar, preventing the telescopic bar from being deformed under pressure, and further improving the stability and anti-tipping ability of the shelf.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0024] like Figures 1 to 5As shown, an anti-tipping metal shelving structure provided in one embodiment of this utility model includes a shelving body 1 and an adjustment assembly 2 installed at the bottom of the shelving body 1. The shelving body 1 includes a base 11, four support columns 12, and multiple platform plates 14. The four support columns 12 are respectively fixedly installed in the dead corners of the base 11, and multiple fixing bars 13 are fixedly installed between the four support columns 12. The platform plates 14 are fixedly installed above the fixing bars 13. The adjustment assembly 2 includes two telescopic bars 21, a two-way lead screw 23, and four connecting rods 25. The two telescopic bars 21 are symmetrically installed at the bottom of the base 11, and adjusting blocks 22 are fixedly installed at both ends of the opposite side of the two telescopic bars 21. The bottom of the base 11 is fixedly... The base 11 has an adjustment groove 111, and the adjustment block 22 is movably locked in the adjustment groove 111. The bidirectional lead screw 23 is located in the middle of the base 11. One end of the bidirectional lead screw 23 is provided with a hexagonal head 231 and extends movably through the base 11 and the fixed bar 13 to the outside of the fixed bar 13. The other end of the bidirectional lead screw 23 is movably located on the side wall of the base 11. Two threads 232 are symmetrically arranged on the outside of the bidirectional lead screw 23. The two threads 232 are in opposite directions. Movable blocks 24 are installed on both threads 232. One end of the connecting rod 25 is movably hinged to both sides of the movable block 24. A fixed plate 211 is fixedly provided in the middle of the opposite side of the two telescopic bars 21. The other end of the connecting rod 25 is movably hinged to the fixed plate 211.
[0025] In one embodiment of this utility model, the hexagonal head 231 drives the bidirectional lead screw 23 to rotate. Based on the threaded connection between the thread 232 and the movable block 24, the movable block 24 is controlled to move axially along the bidirectional lead screw 23. The moving movable block 24 drives the connecting rod 25 to control the extension and retraction of the telescopic bar 21. When the shelf is in use, the telescopic bar 21 extends to increase the bottom area of the shelf, thereby playing a role in preventing tipping. The bidirectional lead screw 23 can also play a self-locking role to prevent the telescopic bar 21 from retracting. When the shelf is not in use, the telescopic bar 21 is retracted to reduce the floor space occupied by the shelf.
[0026] like Figure 2 , Figure 3 and Figure 4 As shown, in another embodiment of the present utility model, a limiting strip 112 is fixedly provided on the side of the adjusting groove 111, and a slot 221 is fixedly opened on the outer side of the adjusting block 22 at the position corresponding to the limiting strip 112, and the slot 221 is movably engaged with the limiting strip 112.
[0027] In one embodiment of this utility model, the limiting strip 112, in conjunction with the slot 221, can improve the fixing effect of the telescopic bar 21 and the adjusting block 22, further enhancing the stability of the shelf and its anti-tipping ability. At the same time, it can also provide a limiting effect, improving the stability of the adjusting block 22 and the telescopic bar 21 when they are extended.
[0028] like Figure 2 and Figure 3 As shown, in another embodiment of the present invention, a limiting groove 113 is fixedly provided at the bottom of the base 11 above the movable block 24, and the upper end of the movable block 24 is movably engaged in the limiting groove 113.
[0029] In one embodiment of this utility model, the movable block 24 is locked and limited by the limiting groove 113, which can effectively prevent the movable block 24 from being subjected to axial torsion of the bidirectional lead screw 23, thus improving the structural life of the bidirectional lead screw 23, the movable block 24 and the connecting rod 25, and thereby improving the overall life of the adjustment component 2.
[0030] like Figure 2 As shown, in another embodiment of the present invention, a support block 114 is fixedly provided at the bottom center of the base 11. The support block 114 is at the same height as the adjustment groove 111, and the bidirectional lead screw 23 moves through the center of the support block 114.
[0031] In one embodiment of this utility model, the support block 114 provides support for the middle part of the base 11, which can prevent the base 11 from collapsing and allow the base 11 to be used as a shelf, effectively utilizing the three-dimensional space of the shelf.
[0032] like Figure 2 As shown, in another embodiment of the present invention, the telescopic bar 21 is movably mounted with support components 3 at both ends, and the support components 3 include support rods 31 and fixing bolts 32.
[0033] Specifically, one end of the support rod 31 is movably hinged to one end of the telescopic bar 21, and a movable groove 121 is fixedly opened inside the support column 12. The fixing bolt 32 is movably installed in the movable groove 121 and movably connected to the other end of the support rod 31.
[0034] In one embodiment of this utility model, the telescopic bar 21 is supported and fixed by the set support rod 31 in conjunction with the movable fixing bolt 32, which reduces the load-bearing capacity of the telescopic bar 21 and thus effectively improves the load-bearing capacity of the telescopic bar 21. This can prevent the telescopic bar 21 from being deformed under pressure, and further improve the stability of the shelf and its ability to prevent tipping.
