杯形臂

杯形臂是隐藏式家具铰链中的关键部件,通常由钢或锌合金制成,连接铰链杯和安装板,传递旋转力并控制门的开启角度。

技术定义与适配语境
典型 杯形臂 会按材料、尺寸公差、适配关系和失效风险在 家具制造 中评估。

杯形臂是隐藏式家具铰链中的关键部件,通常由钢或锌合金制成。它作为铰链杯(嵌入在门中)和安装板(固定在柜体框架上)之间的连接件。该部件传递旋转力并控制门的开启角度,确保平稳运行和精确对齐。其设计包括高度、深度和横向位置的调节机构,以适应各种安装要求。 杯形臂基于杠杆和枢轴机制工作。当门打开时,臂围绕其安装点旋转,将运动从铰链杯传递到安装板。这产生一个受控的弧线,使门能够摆动打开,同时保持稳定性。现代杯形臂通常采用凸轮调节系统,无需拆卸即可微调门的位置。

工作原理
The cup arm operates on a lever and pivot mechanism. When the door is opened, the arm rotates around its mounting point, transferring motion from the hinge cup to the mounting plate. This creates a controlled arc that allows the door to swing open while maintaining stability. Modern cup arms often incorporate cam-adjustment systems that enable fine-tuning of door position without disassembly.
材料
冷轧钢(通常为SPCC或DC01牌号)、锌合金(Zamak 3或Zamak 5)或不锈钢(AISI 304)。表面处理包括粉末喷涂、电镀(镍或锌)或钝化处理以提高耐腐蚀性。

常见问题

What is the purpose of adjustment screws on a cup arm?

The adjustment screws allow precise positioning of the door after installation. Height adjustment moves the door up/down, depth adjustment moves it in/out, and lateral adjustment shifts it left/right for perfect alignment.

Are cup arms interchangeable between different hinge brands?

Generally not interchangeable due to proprietary designs. Cup arms are engineered to work with specific hinge systems from manufacturers like Blum, Hettich, or Grass, with different mounting patterns and adjustment mechanisms.

What causes cup arm failure in furniture hinges?

Common failure causes include material fatigue from repeated stress cycles, corrosion in humid environments, over-tightening of adjustment screws causing thread damage, or excessive load beyond rated capacity.
