The safe lock cylinder has been upgraded to Class B and Super B,and the candidate is super B when purchased.
I used to buy locks to see how much the key teeth are used to judge the quality of the lock cylinder.The main reason is to look at the structure of the lock cylinder.The blade side column structure is often much better than the traditional marble structure.When picking the lock,it is good to ask a professional teacher for advice.Pick according to the situation.
The second measure:pick the lock on the pound to say two,one to see the lock core than the weight two.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,smooth insertion into the lock cylinder in a semi-rotation state,the anti-theft effect is good.
