铰链采用40mm 大杯径标准杯体设计,杯体深度与口径经过精准测算,可适配加厚门板与较重柜体,承重力远超常规小杯径铰链。杯体与铰链臂连接牢固,受力均匀,能稳定支撑各类中小型家具门板,避免因门板过重导致的下垂、脱落问题,满足多场景承重需求。配置标准四孔固定底座,孔位分布均匀对称,受力点科学分散。搭配自攻螺丝锁紧后,与柜体侧板紧密贴合,有效解决长期开关门引发的松动、位移问题,连接稳定性远超两孔底座铰链。安装后可承受高频次启闭,适配家庭日常使用与工装批量装配场景。铰链主体选用高韧性冷轧铁板一体冲压成型,无焊点、无毛刺,结构紧凑抗冲击。表面经防锈喷漆工艺处理,能抵御日常环境中的水汽与灰尘侵蚀,长期使用不易生锈变形,满足普通家装、出租房改造、批量工装等基础场景的使用需求,性价比突出。
The hinge adopts a standard cup design with a large 40mm cup diameter. The depth and caliber of the cup are precisely calculated, making it suitable for thickened door panels and heavy-duty cabinets, with load-bearing capacity far exceeding that of conventional hinges with small cup diameters. The cup and hinge arm are firmly connected, ensuring uniform force distribution. It can stably support various small and medium-sized furniture door panels, preventing sagging and falling-off issues caused by excessive door weight, and meeting load-bearing requirements across multiple scenarios.
Equipped with a standard four-hole fixed base, the hole positions are evenly symmetrical and the stress points are scientifically dispersed. When locked with self-tapping screws, it fits tightly against the cabinet side panel, effectively solving the problems of loosening and displacement caused by long-term door opening and closing. Its connection stability is far superior to that of hinges with two-hole bases. After installation, it can withstand high-frequency opening and closing, making it suitable for daily household use and bulk project assembly scenarios.
The hinge body is integrally stamped from high-toughness cold-rolled iron plate, featuring no welding spots or burrs, a compact structure, and strong impact resistance. The surface is treated with anti-rust spray painting technology, which can resist moisture and dust erosion in daily environments, avoiding rusting and deformation after long-term use. It meets the application needs of basic scenarios such as ordinary home decoration, rental house renovation, and bulk project installation, delivering outstanding cost performance.
