Description

Technical Field

[0001] The utility model relates to the technical field of electronic cabinet hardware, in particular to a universal and convenient cabinet anti-falling device. Background Art

[0002] Currently, most vertical electronic cabinets use a drawer-type or rotating rack structure. The height of the cabinet is often greater than the length and width of the cabinet. When the weight of the drawer is very heavy, it can easily cause the cabinet to tip over, damaging the electronic equipment or even causing personal injury to the operator or researchers. The general method to prevent cabinets from tipping over is to use a rope to fasten the top of the cabinet to a fixed point on the ground. Although this method is simple and convenient, it requires a lot of space, is unsightly, and has low reliability. Alternatively, holes can be drilled in the ground and the bottom of the cabinet can be bolted to the ground, but this requires damaging the ground, is labor-intensive, and leaves the cabinet in a single position. Other clamping devices are very complex in structure and not conducive to convenient operation. Therefore, today's electronic cabinets do not have an anti-tipping clamping device that can be easily operated. Utility Model Content
