No-Mortise Bridge-Type Frog Hinge

No-Mortise Design for Effortless Installation​
Unlike traditional hinges that require precise mortising (cutting slots into door panels or frames for recessed fitting), this hinge mounts directly on the surface without any prior slotting. This design drastically reduces installation time and skill requirements, making it ideal for DIY projects, quick furniture repairs, or mass production where efficiency is critical. It also preserves the integrity of the door panel and frame, avoiding structural weakening from mortising—especially valuable for thin or delicate materials.​
Bridge-Type Structure for Stable Support​
The hinge’s "bridge-type" structure features a central connecting component that spans between the two mounting plates, resembling a small bridge. This design distributes weight evenly across the hinge, enhancing stability and load-bearing capacity. It ensures smooth rotation even with repeated use, preventing sagging or misalignment of connected panels (such as cabinet doors, box lids, or foldable flaps). The bridge structure also adds rigidity, making the hinge suitable for both lightweight and moderately heavy panels.​
Frog-Inspired Shape for Functional Versatility​
The "frog" descriptor comes from the hinge’s unique 轮廓，which often features curved or angled plates that mimic a frog’s limbs when extended or folded. This shape allows for a compact profile when closed, minimizing protrusion and maintaining a clean look. When opened, the design enables a wide range of motion (typically 90° to 180°), ensuring flexible access to the interior of cabinets, boxes, or storage units. The curved edges also reduce the risk of snags or injuries, enhancing user safety.​
Durable Materials & Compatibility​
Constructed from high-quality metals such as zinc alloy, stainless steel, or plated steel, the hinge offers corrosion resistance and long-term durability. It is compatible with various materials, including wood, plywood, MDF, and even lightweight metal panels, adapting to diverse furniture styles and applications. Many models also feature a decorative finish (e.g., brass, nickel, or black oxide) that complements both traditional and modern aesthetics.​
