Gravity gravity type door closer
The invention provides a gravity self-falling type door closer, and relates to the technical field of door closers, the gravity self-falling type door closer comprises a fixed block, a frame and a clamping block, the frame is arranged on the front side of the fixed block, the clamping block is rotatably arranged on the inner side of the frame through an insertion shaft, the clamping block is fan-shaped, a guide plate is arranged below the front side of the fixed block, and the guide plate is fixedly connected with the frame. A limiting shaft is arranged above one end of the clamping block, and one end of the limiting shaft extends out of the frame; a rotary knob is rotationally arranged in the middle of one end of the fixing block, and a tilting rod is connected to the rotary knob. When a user enters a door, the user only needs to stir a tilting rod, lift a limiting shaft, enable a clamping block to rotate and unlock a locking shaft, the door can be pushed to be opened, after entering, the door is closed, the locking shaft is clamped between a guide plate and a frame, the clamping block is pushed to rotate upwards, after the locking shaft is clamped into the inner end, due to the gravity, the clamping block rotates to reset, the locking shaft is locked in a self-falling mode, and the door is closed; and automatic locking and external opening are facilitated, and the construction environment is met.
本发明提供了一种重力自落式闭门器，涉及闭门器技术领域，包括固定块、框架和卡块，所述框架设在固定块的前侧，所述卡块通过插轴转动设在框架的内侧，所述卡块呈扇形，所述固定块前侧的下方设有导向板，所述卡块一端的上方设有限位轴，且限位轴的一端延伸出框架；所述固定块一端的中间位置处转动设有旋钮，且旋钮上连接有翘杆；本发明在进门时，只需要拨动翘杆，提起限位轴，使得卡块转动，解除对锁定轴的锁定，即可推动打开门，进入后，关闭门，锁定轴卡入导向板和框架之间，推动卡块向上转动，当锁定轴卡入内端后，由于重力，卡块转动复位，自落式锁定锁定轴，闭合门，既方便自动锁定，又方便外部开启，满足施工环境。
