[0017] When the radar needs to be locked after being laid flat, the driving mechanism drives the push rod to retract through the transmission mechanism, thereby pulling the locking plate to reversely rotate, so that the locking plate holds the fixing pin installed on the radar array, the locking mechanism stops acting after the micro switch installed on the lower switch mounting plate is triggered, and the radar array is stably locked.

[0018] The utility model has the advantages of:

[0019] The utility model discloses a driving mechanism drives transmission mechanism action, and transmission mechanism drives trapezoidal screw rotation, and the limiting effect of guide groove to trigger block makes that push rod can not rotate, and thereby push rod moves in a straight line under the drive of trapezoidal screw. Push rod drives trigger block to move, and after trigger block contacts micro -switch, driving mechanism stops action. The utility model can drive push rod positive or reverse movement, and two micro -switches control two limit positions of push rod movement, and thereby the utility model can be applied to locking or unlocking.

[0036] In this invention, the drive mechanism 2 drives the transmission mechanism 3 to rotate. The transmission mechanism 3 drives the trapezoidal lead screw 4 to rotate. Due to the limiting effect of the guide groove 14 on the trigger block 6, the push rod 5 will not rotate, thus the push rod 5 moves linearly under the drive of the trapezoidal lead screw 4. The push rod 5 drives the trigger block 6 to move until the trigger block 6 contacts the micro switch 7, at which point the drive mechanism 2 stops operating. This invention can drive the push rod 5 to move forward or backward, and the two micro switches 7 control the two extreme positions of the push rod 5's movement, thus this invention can be used for locking or unlocking.

[0044] When the radar 9 needs to be erected, the driving mechanism 2 drives the push rod 5 to extend through the transmission mechanism 3, thereby pushing the locking plate 83 to rotate, making the locking plate 83 separate from the fixing pin 91 installed on the radar 9 array, and the locking mechanism stops after triggering the micro switch 7 installed on the upper switch mounting plate 71, and then the radar 9 can be erected.

[0045] When the radar 9 needs to be locked after being laid down, the driving mechanism 2 drives the push rod 5 to retract through the transmission mechanism 3, thereby pulling the locking plate 83 to rotate reversely, making the locking plate 83 hold the fixing pin 91 installed on the radar 9 array, and the locking mechanism stops after triggering the micro switch 7 installed on the lower switch mounting plate 71, and the radar 9 array is stably locked.
