The difference between good and bad iron padlock quality
There are many types of iron padlocks available in the market today and they vary in quality. How to distinguish the quality of iron padlock, you can refer to the following:
One is to look at the appearance: the high-quality iron padlock has a clear appearance, smooth and not rough. Purchase skills: Touch the surface of the iron padlock to feel whether the surface is smooth, so as to judge the quality of the iron padlock coating; check whether the lock head, lock body, lock tongue, handle, cladding plate and other components and related accessories are complete; check Whether the surface color of electroplated parts and painted parts is bright and uniform, and whether there are signs of rust, oxidation and damage.
The second is the weight: if the iron padlock is lighter, the anti-theft function and service life of the lock are not ideal. Buying skills: measure the lock cylinder part, the good quality lock cylinder is relatively heavy, on the contrary, the poor quality lock cylinder is very light. Measure the whole iron padlock. The iron padlock made of high-quality materials such as pure copper feels heavier, while the lock made of copper-plated materials is relatively lighter.
The third is to listen to the sound: the copper-plated iron padlock is used as the raw material, and the sound is relatively dull when it is opened, while the sound of copper-plated or stainless steel locks is relatively loud. Purchasing skills: Use two or more products to compare and check to see if they are strong and reliable. Check whether the iron padlock is turned on and whether it can rotate flexibly. Check the insurance structure of the product to see if it is smooth and unimpeded. It is recommended to try each lock at least 3 times.
The fourth is to test the spring: the quality of the spring also determines the service life of the lock. If the spring quality of the lock is not good, the handle is easy to sag, and the life of the lock will be greatly shortened. Purchase tips: Try the toughness of the spring inside the lock. A good spring feels very soft, with moderate hardness. The fifth is the key tooth shape: the mutual opening rate is the mutual opening ratio of the lock and the key. The fewer keys that can open the lock, the more secure and reliable the lock is. Shopping tips: Choose a lock with a large number of teeth on the key, or a special tooth shape. Because the more teeth the key has, the more special it may be, the lower the mutual opening rate of the lock and the better the anti-theft function. Choose an iron padlock with a wide range of key teeth. The tooth shape is too flat, smooth and shallow, the mutual opening rate is high, and the anti-theft function is not good enough.
