Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment, in particular to an electric door closer rotating shaft bracket with an auxiliary positioning installation structure. Background Art

[0002] Electric door closers are also called automatic door closer releasers, electric releasers, etc. They are a mechanism that achieves automatic closing of door leaves through electric control. Electric door closers are different from hydraulic fireproof door closers. They combine the functions of electromagnetic releasers and non-positioning door closers. They contain electromagnetic valves and strong springs. When the door is pushed, the spring is compressed and locked by the electromagnetic valve, so that the door remains normally open. When power is supplied, the electromagnetic valve is released and closed by the rebound impact force of the spring, without buffering function. It was first used in normally open fire doors. Later, because the fire department believed that powering on and closing the door did not meet fire protection regulations, it was not promoted and applied in the fire door market. The fire door market still uses hydraulic automatic door closers.

[0003] Existing electric door closers generally do not have a sensing effect. When multiple people enter, it is necessary to manually block the door to prevent the electric door closer from closing automatically, which reduces practicality. In addition, electric door closers on the market require manual measurement of the door frame before installation, which reduces work efficiency. Utility Model Content
