A device for testing the strength of a
handle of an anti-theft safety door lock belongs to the field of inspection equipment, and is characterized in that a guide rail (2) and a movable base (3) are arranged on the base (1) to realize transverse movement; the movable
machine base (3), the lifting support (4) and the lifting rod (9) form a lifting mechanism, a guide wheel (11) is installed on a transverse support (10), the other end of the transverse support (10) is connected with two adjustable lifting frames (12), and longitudinal movement is achieved.
A diamond force application device (5) is installed on a movable
machine base (3) and is adjusted through a double-spiral lead screw (6), a steel
wire rope (8) is connected with a tension sensor (7), and the steel
wire rope (8) is guided through a guide wheel (11) and is connected with a
door handle clamp (15) on a security door (13). According to the structure of the
door handle clamp (15), a front clamping plate (17) and an opening clamping plate (18) fasten a
door handle (14) through four screws (19), and the door
handle clamp (15) is connected with a tension sensor (7) through a hanging ring (16) and a steel
wire rope (8) to measure force. The requirements of different structures and installation positions of the lock
handle, one-time fixed installation of the safety door and subsequent multiple test items are met.
