How to choose a lock?

How to choose a lock?

The first trick: buy a lock to see the "teeth" of the key. The more teeth, the deeper the teeth, the more complicated the arrangement, the more difficult it is to open, and the better the anti-theft performance.


The second measure: pick the lock on the pound, said two, one to see the lock core. The heavier the weight, the better the quality of the lock cylinder. The more beads in the lock cylinder, the better the anti-theft function.


The third measure: choose the lock core to see the color, look at the work than the color. The quality of the lock cylinder is electroplated, the surface is smooth and the color is bright. Among them, the color is dark yellow, the copper core is relatively strong, the anti-theft performance is better, the color of the lock core is dim, the color is gray and the bubble is zinc alloy, and the anti-theft performance is general.


The fourth measure: the key rotation is inserted into the lock cylinder. The anti-theft performance of the card is poor. After the key is half-inserted, use 5 to 7 minutes to rotate clockwise or counterclockwise and continue to press the key into the lock. The key of the card indicates the lock core. Poor performance, the smooth insertion of the lock cylinder in the semi-rotation state shows that the anti-theft effect is good.
