Abstract

The invention provides a detection device for a door closer of a fire door. The detection device comprises a rack body, a door frame, two groups of hydraulic air cylinders, a hydraulic air cylinder rack and an allocation power box. The door frame is mounted in the middle of the rack body; the hydraulic air cylinder rack is mounted on the rack body and behind the door frame; the two groups of hydraulic air cylinders are mounted on the hydraulic air cylinder rack correspondingly; the allocation power box is installed at the rear end of the rack body; thus, the whole detection device for a door closer of a fire door is formed. The function principle that the hydraulic cylinders convert hydraulic energy into mechanical energy and make straight reciprocating motion (or pendulum motion) is applied to the operation detection of door closers of fire doors, and the detection results are scientific and reasonable and completely accord with related national rules. The detection device is simple in structure, low in manufacture cost and simple to operate and requires no professional technicians in the detection operation process.

Description

technical field [0001] The invention belongs to a detection device, in particular to a detection device of a fire door closer. Background technique [0002] The fire door closer is installed on the upper part of the swing door leaf or built into the door leaf, one-way door opening, usually the operating temperature is -20 ~ 200 ℃, and it is a device combined with metal spring and hydraulic damping. The selection should be made according to the requirements of the width and weight of the door leaf, the fire limit, and the frequency of use. Its function is to ensure that the door is in a normally closed state to avoid the passage of instantaneous fire. Therefore, when producing fire doors, the detection of door closers is a very important link. [0003] At present, the fire doors produced by manufacturers need to be tested by a third party. The inspection process is not only time-consuming, but also expensive. [0004] The detection equipment of other fire door closers is ...
