The invention discloses a sectional door closer and relates to the technical field of refrigerator components. The sectional door closer comprises a rack, wherein a guide rod, a cam, a spring and an end cover are sequentially arranged in the rack; one end of the guide rod is provided with a rotating rod, the other end of the guide rod is an inclined surface I, and a limiting groove is formed in one side edge of the inclined surface I; one end of the cam is provided with an inclined surface II matched with the inclined surface I, the inclined surface I rotates along a step surface arranged on one side of the inclined surface II, and a limiting plane IV for limiting a guide rod rotation range is arranged on one side of the step surface; convex edges are symmetrically arranged on the annularside surface of the cam and slide along guide rails symmetrically arranged on the inner side surface of the rack; and the end cover is fixedly installed in the rack through a pin shaft penetrating through a pin hole, and the spring is installed between the end cover and the cam. According to the sectional door closer, the guide rod and the cam are provided with the inclined surfaces and the limiting groove which are matched with each other, so that the automatic closing of a refrigerator door body is realized, and the problem that a vertical refrigerator door body is not sealed completely after articles are fetched is effectively solved.
本发明公开了一种分段式闭门器，涉及冰箱组件技术领域。本发明包括机架，机架内依次安装有导杆、凸轮、弹簧和端盖；导杆一端设有转动杆，同时导杆的另一端为倾斜面一，并于倾斜面一的一侧边开有限位槽；凸轮一端设有与倾斜面一配合的倾斜面二，倾斜面一沿倾斜面二一侧设有台阶面转动，同时台阶面一侧设有限制导杆转动范围的限位平面四；凸轮环状侧面上对称设有凸棱，凸棱沿机架内侧面上对称设有的导轨滑动；端盖通过穿过销孔的销轴固定安装在机架内，端盖与凸轮之间安装有弹簧。本发明通过导柱和凸轮设有相互配合的倾斜面以及限位槽，实现冰箱门体的自动关闭，有效的解决了立式冰箱门体取拿物品后易出现门关不严的问题。
