A single-spring door hinge comprises a main body installed on a box door and a hinge arm movably hinged to the front end of the main body, the hinge arm is fixed to a box body in a buckled mode, a pull arm is further installed on the hinge arm in a hinged mode, and a sliding arm is further installed in the main body in a front-back sliding mode. The front end of the sliding arm is fixed in a first sliding groove in the main body in a sliding mode through a first pin shaft, the rear end of the sliding arm is fixed in a second sliding groove in the main body in a sliding mode through a second pin shaft, a tension spring is arranged between the tail end of the pull arm and the second pin shaft, and a guide wheel is installed at the front end of the sliding arm. The guide wheel abuts against the outer edge of the hinge arm and can slide on the surface of the hinge arm, the hinge arm is further provided with a locking groove, and when the hinge is in a closed state, the guide wheel falls into the locking groove to be fixed. The hinge has the beneficial effects that automatic reset closing or door opening hovering of the hinge and the locking function after door closing can be achieved only through one spring, the mechanical structure is greatly simplified, and the production and machining efficiency is improved.
一种单簧门铰链,其包括安装在箱门上的主体及活动铰接在其前端的铰链臂,铰链臂卡扣固定在箱体上,所述的铰链臂上还铰接安装有拉臂,所述的主体内还前后滑动式安装有滑移臂，滑移臂的前端通过第一销轴滑动式固定在主体上的第一滑槽内，滑移臂的后端通过第二销轴滑动式固定在主体上的第二滑槽内，所述的拉臂尾端与第二销轴间设置有拉簧,所述的滑移臂的前端安装有导向轮,导向轮抵压在铰链臂的外缘上,并可在其表面滑动,所述的铰链臂上还设置锁止槽，当铰链处于关闭状态时，导向轮落入该锁止槽内固定。本发明的有益效果是：只需要一根弹簧就能够实现铰链自动复位关闭或开门悬停，及关门后的锁止功能，大幅度的简化了机械结构，提高生产加工效率。
