Abstract

The invention discloses a hydraulic damping door closer, belonging to the technical field of door and window hardware, comprising a door closer body, a driving rod, and a driven rod. The door closer body includes a transmission shaft, a connecting rod, a piston, and a casing. The transmission shaft is connected in rotation with the housing, the piston is in transmission connection with the transmission shaft, the piston and the housing form a closed piston cavity, the piston cavity is provided with an energy storage spring, one end of the active rod is fixedly connected with the transmission shaft, and the other end Hinged with the driven rod, the driven rod is provided with a hydraulic damper and the driven rod is provided with a hinged end of the door body. The invention can realize the stable opening and closing of the door body, reduce impact and collision, prolong the service life of the door body, and has the advantages of simple structure, convenient maintenance and small occupied space.

Description

technical field [0001] The invention relates to the technical field of door and window hardware, in particular to a hydraulic damping door closer. Background technique [0002] The existing door closers are mainly hydraulic door closers. The basic components include support guides, transmission gears, return springs, one-way valves, rack plungers, throttle valve cores and housings, end covers, and sealing rings. and connecting rod. Usually, the transmission gear, return spring, one-way valve, rack plunger, and throttle valve core are collectively arranged in the housing, and then the automatic closing of the door body is realized by the connecting rod, and the failure rate is high. [0003] The comparative document CN203640468U discloses a hydraulic damping door closer. In order to prevent the door leaf and the door frame from being damaged due to impact and ensure the stable closing of the door body, the active rod in the door closer is set as a hydraulic damper, and the e...
