The invention provides a door closer capable of randomly adjusting the opening degree of a door leaf, and relates to the technical field of door closers. The door closer capable of randomly adjustingthe opening degree of the door leaf comprises a mounting box and a door body, a first mounting block is fixedly connected to the side wall of the mounting box, a wall mounting assembly is rotatably connected to the side wall of the first mounting block through a rotating shaft, a first fixing block is fixedly connected to the interior of the mounting box, a hydraulic cylinder is fixedly connectedto the side wall of the first fixing block, and an auxiliary guide assembly is fixedly mounted at position, away from the first fixing block, inside the mounting box. According to the door closer capable of randomly adjusting the opening degree of the door leaf, the door body is opened to a specified degree by pressing a door opening button and a hydraulic cylinder starts to work, the door body isclosed to a specified degree by pressing a door closing button and the hydraulic cylinder starts to work, the requirements of half opening or full opening and the like of the door body can be met according to actual application, other objects are not needed, convenience and attractiveness are achieved, and meanwhile, traffic is not influenced.
Description
technical field [0001] The invention relates to the technical field of door closers, in particular to a door closer which can arbitrarily adjust the opening degree of a door leaf. Background technique [0002] Door closers are mainly used in commercial and public buildings, but they are also used in homes. They have many uses, the most important of which is to make the door close by itself to limit the spread of fire and the ventilation in the building. 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. The door closer is a spring-like hydraulic device on the door head. When the door is opened, it can be compressed and released to automatically close the door. It has the function of a spring door, which can ensure that the door is accurately and tim...
