Because the test rack 1 and the door frame are fixed, whether the gap between the door leaf and the door frame is increased can be known by observing the distance between the first distance sensor 19 and the side wall of the door leaf, and the use durability of the door leaf can be further judged. Similarly, whether the rebound parallelism of the handle is changed or not can be known by observing the change of the distance between the second distance sensor 20 and the top surface or the bottom surface of the handle, and the use durability of the handle can be further judged.

Still be provided with contact switch 23 on the lateral wall of installation pole 21, when test device 3 promoted the door leaf and install pole 21 relatively and press contact switch 23, test device 3 switches the user state, and the control spring bolt is popped out and is inconsistent with pressure sensor 22, can learn the spring bolt through the detection of pressure sensor 22 receiving end and pop out the distance of door leaf, further can judge the spring bolt, the degree of durability of lock promptly. Of course, the pressure sensor 22 may also be a displacement sensor, and the distance that the lock tongue is ejected out of the door leaf can be known by the distance that the lock tongue pushes the displacement sensor. It should be noted that, when the receiving end of the pressure sensor 22 receives a signal, the testing device 3 controls the lock tongue to retract and switches the use state again to control the door leaf to close.

The test rack 1 is provided with a counting device 24 at the position opposite to the door leaf, when the door leaf is closed, the counting device 24 counts the door leaf, the counting device 24 can adopt a press counting sensor or other electromagnetic matched counters, and therefore the relation between the durability and the using times of each part can be observed.

Certainly, in order to improve the usability and automation degree of the experimental device, the door leaf may be provided with a second contact switch 26 opposite to the handle pull-down position, and when the second contact switch 26 is pressed, the driving assembly 5 switches the use state of rotation or ejection.

The specific use mode of the experimental device for the door switch detection experiment is as follows: starting the testing device 3, the motor 9 controls the rotating shaft 6 to rotate so as to twist the key to enable the bolt to retract, and in the process, the stay cable 8 is tensioned to pull down the handle, so that the limitation between the door leaf and the door frame is relieved. And the second contact switch 26 is pressed while the handle is pulled down, and then the test device 3 switches the use state to control the rotating shaft 6 to eject the door leaf. When the door leaf is ejected to be opposite to the installation rod 21, the door leaf presses the first contact switch 23, then the testing device 3 switches the use state to control the spring bolt to be ejected to be opposite to the pressure sensor 22, and after the receiving end of the pressure sensor 22 receives a signal, the testing device 3 controls the spring bolt to be retracted and switches the use state again to control the door leaf to be closed to one side of the door frame. After the door leaf is closed, the counting device 24 can count and observe the door leaf and control the testing device 3 to screw out the lock tongue to be buckled with the door frame, and then the lock tongue is controlled to be retracted again, so that one cycle of opening and closing the door leaf by the testing device is completed. It should be noted that the second contact switch 26 is set to be in a use state where the single pressing controls the rotating shaft 6 to eject and the double pressing does not make any instruction, so that the second contact switch 26 is not easy to conflict with the use of the pressure sensor 22, and the experimental device can automatically cycle the door leaf to open and close.
