[0002] A material rack refers to a frame that can load processed materials, and mobile material racks can facilitate the loading and transportation of materials and are widely used in the manufacturing industry.

[0003] The existing multi-layer mobile rack can place materials in multiple layers when in use. However, in actual use, if the space occupied by the materials is small and the density is large, the spacing between the loading layers of the multi-layer rack is fixed, which causes the overall center of gravity of the rack to be high when loading materials, which in turn leads to the accidental tilting of the rack during movement, causing the rack to topple over as a whole and causing damage to the materials. For this reason, we propose an easy-to-use multi-layer mobile rack. Utility Model Content

[0029] When the whole is loaded and unloaded, the connection and stabilization mechanism 8 can be connected and coordinated with the ground, thereby improving the overall stability of use and avoiding collision during loading and unloading, which causes the whole to deviate under the action of the universal wheel 7.

[0030] In another embodiment, if Figure 2 As shown, the movable loading mechanism 5 includes a loading box 9, a guide protrusion 10 is provided on the outer end of the surface of the loading box 9, both ends of the loading box 9 are fixedly connected with a connecting mounting plate 11, a connecting positioning mechanism 12 is fixedly connected to the side of the connecting mounting plate 11 away from the loading box 9, a first handle 13 is fixedly connected to the middle part of the side of the connecting mounting plate 11 away from the loading box 9, and a fixed through groove 14 is opened inside the first handle 13.

[0031] It is convenient to adjust the connection positioning mechanism 12 while holding the first handle 13, and to move and adjust the connection mounting plate 11, the loading box 9 and the guide protrusion 10, so that the distance between adjacent loading boxes 9 can be adjusted. After the adjustment is completed, the position of the loading box 9 can be fixed by the mutual connection and cooperation between the connection positioning mechanism 12 and the fixed positioning hole 6, which is easy to operate.

[0032] In another embodiment, if Figure 3 and Figure 4 As shown, the connecting and positioning mechanism 12 includes a connecting sleeve 15, the interior of the connecting sleeve 15 is movably connected to a movable positioning rod 16, the outer surface of the movable positioning rod 16 is fixedly sleeved with a force ring 17, a force spring 18 is fixedly connected between one side of the force ring 17 and one end of the interior of the connecting sleeve 15, and the end of the movable positioning rod 16 away from the connecting mounting plate 11 is fixedly connected to a connecting pull arm 19.

[0033] It is convenient to pull the connecting arm 19, drive the movable positioning rod 16 and the force-bearing ring 17 to move, compress the force-bearing spring 18, so that one end of the movable positioning rod 16 can be pulled out from the inner side of the fixed positioning hole 6, loosen the connecting arm 19, and allow the force-bearing ring 17 to reset the movable positioning rod 16 under the action of the force-bearing spring 18, so that one end of the movable positioning rod 16 is reinserted into the inner side of the fixed positioning hole 6, thereby connecting and positioning.

[0035] The guide protrusion 10 can stably move inside the fixed guide groove 4, and the connecting arm 19 can stably move inside the fixed through groove 14, which is easy to operate.

[0036] In another embodiment, if Figure 5 As shown, the connection and stabilization mechanism 8 includes a fixed mounting plate 20, a movable connecting plate 21 is movably connected to the inner side of the surface of the fixed mounting plate 20, a fastening bolt 22 is threadedly connected between the movable connecting plate 21 and the fixed mounting plate 20, a fixed sleeve block 23 is symmetrically provided on the surface of the movable connecting plate 21, an electric telescopic rod 24 is fixedly connected to the inside of the fixed sleeve block 23, an extension rod 25 is fixedly connected to the output end of the electric telescopic rod 24, and a connection protection bottom block 26 is fixedly connected to the bottom end of the extension rod 25.

[0037] The electric telescopic rod 24 can push the extension rod 25 and the connection protection bottom block 26 downward, so that the connection protection bottom block 26 is in contact with the ground, and the whole is lifted up, thereby improving the overall stability of use.

[0038] In another embodiment, if Figure 5 As shown, a second handle 27 is symmetrically provided on the surface of the movable connecting plate 21 .

[0039] The second handle 27 can be easily moved, thereby driving the movable connecting plate 21, the fixed sleeve block 23, the electric telescopic rod 24, the extension rod 25 and the connecting protective bottom block 26 to move, so as to facilitate disassembly and assembly.

[0040] The working principle of the utility model: during use, the electric telescopic rod 24 can push the extension rod 25 and the connecting protective bottom block 26 downward, so that the connecting protective bottom block 26 contacts with the ground, and the whole is lifted up, thereby improving the overall stability of use. When the first handle 13 is held, the connecting pull arm 19 is pulled to drive the movable positioning rod 16 and the force-bearing ring 17 to move, compressing the force-bearing spring 18, so that one end of the movable positioning rod 16 can be pulled out from the inner side of the fixed positioning hole 6, and then the first handle 13 is moved downward, driving the connecting mounting plate 11, the loading box 9 and the guide protrusion 10 to move downward.

Under the action of the force spring 18, the force-bearing ring 17 can drive the movable positioning rod 16 to reset, so that one end of the movable positioning rod 16 is re-inserted into the inner side of the fixed positioning hole 6, thereby connecting and positioning, and loading the inner side of the loading box 9 after the adjustment is completed, and then adjusting the position of another loading box 9 so that the spacing between the loading boxes 9 can be controlled, and the overall weight is made as low as possible, thereby reducing the overall center of gravity. After loading is completed, the electric telescopic rod 24 lifts the extension rod 25 and the connecting protective bottom block 26 upward, so that the connecting protective bottom block 26 is separated from the ground, and the universal wheel 7 is in contact with the ground, so that the whole can be moved quickly. The overall structure is simple and the operation is convenient and fast.
