During the investigation, many of the bicycle storage places used this cheap crucible key lock. After hearing the reporter's experimental results, many citizens questioned: "This kind of car lock is so unsafe, what kind of lock should the lock bike use?"
For how to choose bicycle locks, Director Wang Xiangming suggested that the first thing to go to the formal shopping malls to buy locks, the general cost of locks is about forty or fifty yuan, so the choice of locks of more than sixty or seventy yuan is relatively safe; in addition, according to the locks The weight is used to identify. Relatively speaking, the heavier the lock is, the higher the safety is. At the same time, when you buy, you can ask the merchant to provide more locks and do the experiment on the spot.
The reporter organized some car locks from low to high.
1, the car comes with a lock
The structure is very simple, it can be opened in a few times, and it is too thin and unsafe.
2, horseshoe lock
It is a circular lock that surrounds the wheel. Most lock cylinders are easily cracked and unsafe.
3, iron chain lock
The chain lock is strong on the surface but is easily cut by pliers. A chain of one ring and one ring is basically not resistant to the violence of the pliers, and the wire twisting type is thick enough to be considered.
4, U-lock
As long as it is not a poor quality lock, it is much stronger than the chain lock. The U-lock is fixed at a fixed point and fixed at two points, that is, whether the U-word and the word can be separated. The weakness of a fixed U-lock is the intersection of the U-shape and the word. The hinge structure is bound to cause insufficient thickness and can be cut by the pliers. The two-point fixed U-lock has good anti-theft performance.
5, idling lock
The lock cylinder can be idling, and the anti-smashing effect is good. It is the best car lock on the market, but the price is not cheap.
