Abstract
The invention discloses a door closer capable of self-locking and remote control, comprising a cylinder liner, a connecting pipe, a piston, a connecting rod, a right limit block, a first spring, a pull rod, an upper limit block, a lower limit block, and an electromagnetic switch , the second spring and the rotating shaft; the door closer of the present invention is designed with a self-locking device, so that after the door closer is self-locked, the door closing function becomes invalid, but at the same time, the damping effect is maintained, and the door with the door closer installed can be in any position , when a fire occurs, the fire door can be closed by remote fire control or manually triggering the self-locking device of the door closer, and the status is fed back to the fire control center at the same time; action, the fire door is closed. Secondly, when the door closer is self-locking, the fire door is in any state, which is convenient for people to use. Furthermore, unless the self-locking condition of the door closer is triggered, the door closer will not self-lock. In addition, the door closer still has a certain damping when it is self-locking, and the damping is adjustable.
Description
technical field [0001] The invention relates to the technical field of building fire protection, in particular to a door closer capable of self-locking and remote control. Background technique [0002] Fire doors must be in a normally closed state during a fire, so it is necessary to install a door closer on the fire door to keep the fire door normally closed, but in actual application, the normally closed fire door brings a lot of inconvenience to daily life, such as many Under the circumstances, people try every means to disable the door closer for convenience, so that the fire door cannot meet the fire protection requirements. The present invention solves the problem that the fire door is in a free state at ordinary times, and is normally opened or closed according to people's needs. When a fire occurs, the fire door is closed by remote fire control or manually triggering the self-locking device of the door closer. [0003] At present, the door closers on the market are ...
