The invention relates to the technical field of door closers, and discloses a labor-saving door opening mechanism of a door closer. The labor-saving door opening mechanism comprises a shell, wherein aconnecting rod is movably connected to the upper end of the shell, a ratchet piston rod is in movable and sleeved connection to the middle part of the inner cavity of the shell, and the middle part of the ratchet piston rod is movably connected with one end of the connecting rod through a driving wheel. By arranging a lever labor-saving structure, when a door plate is pushed to enable the door closer to work, the driving wheel can be driven to rotate through the connecting rod, so that the ratchet piston rod moves towards the side away from a hydraulic box, when the ratchet piston rod moves,a clamping block moves towards the right side under the action of friction force, an axis rod on the right side of a lever block is clamped, when the ratchet piston rod pushes one end of the lever block to enable the first spring to be compressed, an arm of force is increased, when the door is opened, the compression force of the first spring is reduced, and the problem that due to the fact that the rigidity of a spring of a traditional door closer is high, people with small strength such as old people or children cannot open the door is solved.
本发明涉及闭门器技术领域，且公开了一种闭门器的省力开门机构，包括壳体，所述壳体的上端活动连接有连接杆，所述壳体内腔的中部活动套接有棘齿活塞杆，所述棘齿活塞杆的中部通过驱动轮与连接杆的一端活动连接。本发明通过设置杠杆省力结构，使得当通过推动门板，使闭门器工作时，能通过连接杆带动驱动轮转动，使得棘齿活塞杆向远离液压箱的一侧移动，并在棘齿活塞杆移动时，使卡块在摩擦力的作用下向右侧移动，从而使杠杆块右侧的轴心杆卡住，从而使得棘齿活塞杆推动杠杆块一端使第一弹簧压缩时，力臂增大，使得在开门时，使第一弹簧压缩的力减小，避免了由于传统闭门器弹簧刚度较高，导致老人或小孩等力气较小人员无法使门打开的问题。
