The invention discloses a door hinge structure. A pressure cylinder with a piston rod, a push-and-pull part and a connecting part are sequentially arranged between a fixed arm on a cabinet body and a rotating head on a door plate; the piston rod and the push-and-pull part are fixed through two rivets; the push-and-pull part and the connecting part are hinged through a stress rod; a rolling sleeve is sleeved on the stress rod; and the end part of a torsion spring mounted on the fixed arm is propped against the rolling sleeve and applies an acting force pointing to one side of the rotating head. According to the door hinge structure, except for the movement of the piston rod in the movement process, other parts mainly achieve opening and closing of the door plate through rotation, and the requirement for arranging a U-shaped sliding groove in an existing door hinge is omitted, so that the machining precision requirement of a door hinge is improved, the accuracy of opening and closing operation of the door hinge is improved, and the door plate is effectively prevented from jumping to affect the door closing effect; and meanwhile, the parts cannot be damaged due to abrasion, the working stability of the door hinge is effectively improved, the service life of the door hinge is effectively prolonged, and the manufacturing and using cost is reduced.
一种门铰链结构，柜体上的固定臂和门板上的转动头之间依次设置带有活塞杆的压力缸、推拉件和连接件，活塞杆与推拉件之间通过两个铆钉进行固定，而推拉件和连接件之间则通过受力杆铰接，受力杆上套有滚动套，安装于固定臂上的扭簧的端部与滚动套相抵并其施加指向转动头一侧的作用力。该种门铰链结构在运动过程中除了活塞杆的移动之外，其余零部件主要通过转动而实现门板的开闭，取消了现有门铰链中U形滑槽的设置需要，从而提高了门铰链的加工精度要求，也提高了门铰链开闭操作的准确性，并有效防止门板产生跳动而影响关门效果，同时也不会因磨损而损坏零部件，有效地提高了门铰链的工作稳定性和使用寿命，降低制造和使用成本。
