Bidirectional hidden type automatic door closer
The invention provides a bidirectional hidden type automatic door closer, and relates to the technical field of door closers, the bidirectional hidden type automatic door closer comprises a block body and a first gear, the first gear is rotatably arranged at one end of the top of the block body, limiting columns are arranged on the two sides of the top of the first gear, an avoiding groove is formed in the inner side of the first gear, and a guide groove and an arc groove are formed in the block body; a moving block is movably arranged in the guide groove, and an inner cavity is formed in the moving block; a block body is fixed to the end, close to a door shaft, of a door plate, an avoiding groove penetrates through the door shaft, a first gear is located on the rotating axis of the door plate, a door frame is clamped through two sets of limiting columns, and when the door plate drives the block body to rotate, the first gear does not rotate, a second gear is driven to rotate, a cam is driven to rotate, and a movable block is extruded to move leftwards; the connecting column is pulled, the piston moves leftwards, the spring is extruded, and after the door is opened, the door plate is driven to reset through spring reset, installation is convenient, grooving is not needed, hiding is convenient, and bidirectional door closing can be achieved.
本发明提供了一种双向隐藏式自动闭门器，涉及闭门器技术领域，包括块体和第一齿轮，所述第一齿轮转动设在块体顶部的一端，且第一齿轮顶部的两侧均设有限位柱，所述第一齿轮的内侧设有避让槽，所述块体的内部设有导向槽和弧槽，所述导向槽的内部活动设有移动块，且移动块的内部设有内腔；本发明只需要将块体固定到门板上靠近门轴一端，利用避让槽穿过门轴，使得第一齿轮位于门板的转动轴心上，利用两组限位柱卡上门框，使得门板带动块体转动的时候，第一齿轮不转，驱动第二齿轮旋转，带动凸轮旋转，挤压移动块向左移动，拉动连接柱、活塞向左移动，挤压弹簧，开门后，利用弹簧复位驱动门板复位，安装方便，无需开槽，便于隐藏，可以双向闭门。
