Device for detecting service life of fire escape lock

Abstract

The invention discloses a device for detecting the service life of a fire escape lock. The fire escape lock is arranged on a door to be detected. One side of the door to be detected is hinged to a door frame. The detection device includes a crank mechanism, a link mechanism and a sliding table mechanism. One end of the crank mechanism is hinged to the door frame, and the crank mechanism rotates coaxially with the door body. The other end of the crank mechanism is fixedly provided with a detection block. The sliding table mechanism comprises a lead screw sliding table and a detection fixing seat. The lead screw sliding table can be horizontally rotationally arranged on the detection fixing seat. One end of the link mechanism is hinged to the crank mechanism, and the other end of the link mechanism is fixed to the sliding table of the lead screw sliding table. The motor of the lead screw sliding table drives a lead screw to drive the sliding table to move forward. The sliding table drives the link mechanism to push the detection block of the crank mechanism in order to press down the fire escape lock to unlock the fire escape lock and open the door. The device of the invention can effectively and conveniently unlock the fire escape lock and open the fire escape door. The device of the invention has a simple structure, a stable and reliable implementation process, and high detection efficiency.
