In one embodiment of the security inspection apparatus provided in the present invention, please refer to fig. 1 to 4, which includes a bracket, a driving device, a scanning arm 7, a proximity switch 10 and a control device.

The driving device is arranged on the bracket, and the scanning arm 7 is connected with the output end of the driving device. The proximity switch 10 and the driving device are respectively connected with the control device in a communication way. The control device can be directly arranged on the scanning arm 7 and can collect and process data, and specifically, the control device is used for controlling the driving device to stop continuing the forward operation when the proximity switch 10 detects that the scanning arm 7 moves to a preset position, so that the driving device stops operating or starts operating in a reverse direction. The proximity switch 10 may be a photoelectric proximity switch, a capacitive proximity switch, or a hall proximity switch.

When the detection object moves to the detection position set on the bracket, the control device controls the driving device to start so as to drive the scanning arm 7 to scan, and when the proximity switch 10 detects that the scanning arm 7 moves to the preset position, the driving device stops running, and the stroke of the scanning arm 7 in the direction is finished.

In this embodiment, the proximity switch 10 is used to limit the scanning arm 7, so that the mechanical impact on the scanning arm 7 during limiting can be reduced, the scanning arm 7 is protected, and meanwhile, the proximity switch 10 can provide a signal to the control device to control the driving device to stop running in time, so that the scanning arm 7 can be reliably stopped scanning.

Further, the driving device is a rotary driver 5 arranged on the top of the support, and the rotation center line of the output end of the rotary driver 5 is horizontally arranged. The top of the scan arm 7 is connected to the output of the rotary drive 5 so that the scan arm 7 oscillates under the drive of the drive means. As shown in fig. 1, the scanning arm 7 has a top end connected to the output end of the rotary actuator 5 and a bottom end serving as a free end, and forms a swing arm with respect to the output end of the rotary actuator 5. The swing arm type scanning arm 7 is adopted, so that the scanning range can be ensured, and the occupied space of the rotary driver 5 is small.

The simultaneous driving of different scanning arms 7 is realized through one rotary driver 5, which is beneficial to ensuring the synchronism of scanning and saving the use cost. Of course, in other embodiments, each scan arm 7 may be driven by a respective driver.

Further, as shown in fig. 1, the rotation center line of the output end of the rotary driver 5 is located at the middle position of the top of the bracket, and proximity switches 10 are respectively disposed on the bracket at two sides of the rotation center line, so that the corresponding proximity switches 10 are used for limiting when the scanning arm 7 swings to the left and right sides with the vertical state of the scanning arm 7 as a reference. As shown in fig. 2 and 4, two proximity switches 10 are disposed on one side of the center line of rotation of the bracket, and one proximity switch 10 is disposed on the other side of the center line of rotation of the bracket, wherein one proximity switch 10 performs a start point calibration, the other proximity switch 10 performs an end point limit, and the proximity switch 10 on the other side performs another end point limit. When the scanning arm 7 swings from the vertical state to both sides, it can move only to the end limit defined by the proximity switch 10 in the corresponding direction at most. In addition, the proximity switch 10 for starting point correction can be used when the scanning arm 7 has a need for position correction.
