frog four-inch hydraulic hinge smooth opening and closing anti-clamp hand plate cabinet closet door connecting hardware

The hinge adopts a frog-inspired biomechanics structure, with the connection node between the hinge arm and the base simulating the force principle of the frog leg joint. When opening and closing, the force is more evenly distributed, and the bearing capacity is improved by 30% compared to conventional hinges. The unique frog-shaped clamp design makes the door panel and base fit more tightly, effectively avoiding long-term high-frequency opening and closing-induced looseness and displacement problems, stable support for small and medium-sized furniture door panels. The hinge is a standard size of 4 inches (100mm), completely matching the hole size of most board furniture on the market, without the need for additional hole expansion or modification, directly compatible with wardrobe, cabinet, shoe cabinet, storage cabinet and other types of household cabinet doors. The standardized size design significantly reduces the installation difficulty, and even beginners can quickly complete the assembly, meeting the needs of DIY home decoration, mass furniture production and other scenarios. Equipped with high-quality hydraulic damping cylinder, the cabinet door automatically triggers the buffer function when closing to 15° to achieve smooth, stable, and silent closure, solving the problem of noise when closing the door. The buffer structure can effectively avoid the rapid rebound of the door panel to clamp the hand, especially suitable for families with the elderly and children; At the same time, it reduces the collision damage between the door panel and the cabinet body, reduces the probability of door panel deformation, and extends the overall service life of the furniture.
