[0002] A specialized fixing device for securing warning tape during switchgear inspection, maintenance, or operation is disclosed, particularly suitable for warning tape holders with strong magnetic adsorption, quick assembly and disassembly, and anti-slip functionality. In switchgear maintenance operations in the power industry, existing warning tape fixing devices present three major safety hazards: traditional magnetic holders are prone to detachment due to magnetic attenuation or smooth cabinet surfaces, especially during equipment vibration or external impacts, leading to isolation failure; the simple clamping structure lacks a self-locking mechanism, making the warning tape susceptible to slippage due to tension changes or accidental contact, failing to maintain an effective isolation area; and the fixing device lacks compatibility, unable to accommodate various warning tape widths and prone to lateral displacement on smooth metal cabinet surfaces, exacerbating safety risks. These defects directly threaten the safety of operators and urgently require technical improvements through enhanced magnetic stability, optimized anti-slip structures, and expanded compatibility. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a special warning tape fixer for switch cabinets, which has the advantage of facilitating the limiting and fixing of the warning tape.

[0007] As a preferred technical solution of this utility model, the serrated clamping teeth are adapted to a five-centimeter-wide warning tape, and the anti-detachment buckle is an elastic buckle structure, forming a closed ring after clamping.

[0008] As a preferred embodiment of this utility model, the movable clamping arm is controlled to open and close by a push-button opening and closing mechanism, and the operating force of the rotating shaft is less than 15 Newtons.

[0009] As a preferred technical solution of this utility model, the fixed clamping arm and the movable clamping arm are integrally injection molded from polycarbonate (PC) material, and the temperature resistance range of the fixed clamping arm and the movable clamping arm is from -40 degrees to 80 degrees.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention utilizes a dual-magnet layout to enhance adsorption force, achieving a vertical pull-out force of 120 Newtons and a lateral anti-slip force of 260 Newtons, ensuring stable adsorption under complex working conditions. A silicone anti-slip pad and anti-detachment buckle provide double protection against vibration and impact. A one-handed press-type quick-release mechanism allows for loading and unloading within three seconds, improving work efficiency.

After embedding the warning tape into the serrated clamping teeth 4, the embedded slot 8 and bolt 10 are secured between the clamping arm 3 and the movable clamping arm 9. The rotating shaft 5 is then released to complete the fixation. The entire process takes ≤3 seconds. Finally, the anti-detachment buckle 7 automatically locks, forming a double anti-detachment structure of clamping teeth engagement and buckle damping. Even under lateral tension, the warning tape remains at zero displacement. The engineering plastic body and aging-resistant silicone components ensure 25 years of reliable service in environments ranging from -40°C to 80°C. Compared to traditional fasteners, this fastener features a dual-magnet layout to enhance adsorption force, with a vertical pull-out force of 120 Newtons and a lateral anti-slip force of 260 Newtons, ensuring stable adsorption under complex working conditions. A silicone anti-slip pad and anti-detachment buckle provide double protection against vibration and impact.

The serrated clamping structure is compatible with warning tapes of any width within five centimeters, and the buckle locking design prevents lateral displacement. The engineering plastic body has passed 80-degree temperature resistance and corrosion resistance tests, and with the anti-aging silicone pad, it promises a 25-year long-term service period, comprehensively solving the pain points of traditional products such as poor stability, low applicability, and cumbersome operation.

[0026] Working principle and usage process of this utility model:

[0027] First, the staff attaches the bottom surface of the silicone anti-slip pad 2 of the strong magnet 1 to the metal cabinet. The dual strong magnet 1 generates enhanced adsorption force, which, together with the silicone anti-slip pad 2, achieves double stability. Pressing the opening / closing button 6 unfolds the movable clamping arm 9. After embedding the warning tape into the serrated clamping teeth 4, the embedded slot 8 and bolt 10 are locked between the clamping arm 3 and the movable clamping arm 9. Now, the rotating shaft 5 is released to complete the fixation. The whole process takes ≤ three seconds. Finally, the anti-detachment buckle 7 automatically locks, forming a double anti-detachment structure of clamping teeth engagement and buckle damping. Even under lateral tension, the warning tape can still maintain zero displacement. The engineering plastic body and aging-resistant silicone components ensure a reliable service life of 25 years in environments ranging from -40°C to 80°C.
