and an elastic part 70 located between the movable plate 20 and the fixed seat 50 and connected to the movable plate 20.
The base 10 is used for supporting the movable plate 20, the crank block mechanism 30, the fixed seat 50, the sensor 60 and the elastic part 70, and providing support for the installation of the crank block mechanism 30, the driving part 40, the elastic part 70 and the fixed seat 50. In the present embodiment, the base 10 may have a box-type structure for accommodating the driving part 40.
The first lock body and the second lock body can be respectively a lock ring and a lock catch part of the lock, but the invention can be used for detecting the performance of the lock with the lock ring and the lock catch separated, and is suitable for telescopic intelligent locks and plug-pull and life test of various plug-pull data interfaces. The sensor 60 collects signals and compares the signals with the signals of the sensor inside the lock, and the state of the lock is judged in an AND operation mode. The lock also has an internal sensor that self-tests the lock. The motor 40 is located inside the cabinet at the lower portion of the lock testing device 100 and drives the slider-crank mechanism 30 to operate.
The lock testing device 100 of the present disclosure carries the first lock body through the movable plate 20, and an installation portion may be disposed on a surface of the movable plate 20 close to the fixed seat 50 to fix the first lock body, or the first lock body may be directly fixed on the movable plate 20.
