The invention relates to the related technical field of door closers, and discloses a hidden adjustable door closer. The hidden adjustable door closer comprises a door body, a door closing device is fixedly installed on one side of the top of the inner wall of the door body, a damping buffer device is fixedly installed on the inner wall of the door closing device, and a driving spring is fixedly installed on one side of the damping buffer device; and a fixing frame is movably installed on one side of the top of the door body, an adjusting gear is movably installed at the bottom of a rotating shaft of the fixing frame, and a movable gear engaged with inner teeth of the adjusting gear is movably installed on the inner wall of the adjusting gear. According to the hidden adjustable door closer, a driving spring in the door closing device is compressed through a driving rope, thus in the door opening process, the driving rope and a rope drum are fixed, the torque of pushing a door handle bya person is increased, the force required for compressing the driving spring can be greatly reduced, the door opening strength is further reduced, and finally, the purpose of conveniently opening a door is achieved.
Description
technical field [0001] The invention relates to the related technical field of door closers, in particular to a concealed adjustable door closer. Background technique [0002] The significance of the door closer is not only to automatically close the door, but also to protect the door frame and the door body (smooth closing). More importantly, the door closer has become a non-negligible executive part of the intelligent management of modern buildings. Door closers are mainly used in commercial and public buildings, but they are also used in homes, where the most important use is to make the door close by itself. [0003] The working principle of the existing door closer is mainly as follows: when the door is opened, the door body drives the connecting rod to move, and the transmission gear is rotated to drive the rack plunger to move to the right. When the plunger moves to the right, the spring is compressed, and the hydraulic oil in the right chamber is also compressed. T...
