AI Technical Summary
The existing aluminum alloy door handle has poor anti-theft effect, mainly because of its simple structure, making it difficult to effectively prevent theft.
An aluminum alloy door handle with an anti-theft mechanism is designed, and an anti-theft mechanism is formed by providing a partition, a rotating disc, a traction line and a limiting rod on the outer shell of the door handle. The anti-theft mechanism uses a special groove to cooperate with the residents' special square rod to drive the rotating disc to rotate, pull the limit rod to get out of the fixed cylinder, unlocking the partition, thereby improving the anti-theftness of the door handle.
Through the installation of partitions and the design of the anti-theft mechanism, the keyhole can be effectively blocked. In conjunction with the use of special square rods, the rotation of the rotating disc and limit rods can be driven, so that the keyhole is exposed, which is convenient for residents to unlock the lock, and significantly improves the anti-theft effect of the aluminum alloy door handle.
