Portal anti-collision parking space lock
The invention relates to a parking space lock, in particular to a portal anti-collision parking space lock, mainly comprising a base, a lock cylinder, a bolt, a retaining bar, a soft cable or pull rod, and a round pin or positioning disc. The portal anti-collision parking space lock is characterized in that the base is fixed on the ground through screws, the lower end of the retaining bar is movably fixed on the base through the round pin being inserted into a round pin hole, the lock cylinder is fixed to the retaining bar or inside the base, the bolt is disposed inside the retaining bar or the base and is connected with the lock cylinder through the soft cable or pull rod, the round pin or positioning disc is unidirectionally disposed on the base or the retaining bar through a pretension torsion spring, and the round pin or positioning disc is provided with a bolt hole for fastening in the bolt. When the parking space lock is impacted by a vehicle, the retaining bar and the round pin never rotate with each other since the bolt inside the retaining bar is fastened in the bolt hole of the round pin; however, the round pin is unidirectionally disposed on the base through the pretension torsion spring, the unidirectional arrangement is exactly consistent with a stress direction when the parking space lock suffers an impact, the retaining bar will drive the round pin to overcome the resistance of the torsion spring and moves with a vehicle, and the parking space lock is thus protected being impacted.
