How to choose a bearing door lock - Zongyi Hardware

Firstly, the material of the lock should be considered. From good to bad, there are copper, stainless steel, zinc alloy, aluminum, iron, etc. Copper locks are good, while it is recommended to buy 304 material for stainless steel and space aluminum for aluminum. Never buy iron locks, because if the surface plating layer falls off, it will rust and the lock will be useless in less than a month.

When it comes to stability, it mainly manifests in the lock core, key, and lock body. A lock core with fewer pinholes is easy to open, and a skilled locksmith or thief can open it in a few seconds with a simple tool. However, when we live inside, stability and privacy cannot be guaranteed, which is very dangerous. Currently, most manufacturers in China produce such low-end products. The mutual opening rate of lock cores refers to the percentage of the number of times the lock has been opened and the number of times it has been tried to open. The national industry standard is less than 0.53. If the mutual opening rate of lock cores is high, hundreds or thousands of households in a large community may install door locks and their neighbors' keys may open each other, which is quite convenient but the stability coefficient is high. Greatly reduced. We can distinguish it from the tooth patterns on the key. The more tooth patterns, the better. Lock cores with less than 4 tooth patterns should never be bought, The lock body should be purchased with multiple safety features, such as double or multiple tongues. For those with a single tongue, it should be purchased with an explosive type, which makes it difficult for thieves to open. If it is a single tongue, it can be opened with an ID card or bank card because it only has one slanted tongue and no safety. However, the explosive single slanted tongue has much higher stability.

The smooth and beautiful appearance of the door lock is related to the owner's face and cannot be ignored. When choosing, attention should be paid to the following points: 1. Whether the surface of the lock body is smooth and has any defects that affect its appearance. 2. Whether the key is flat and smooth. 3. You can insert the key into the lock cylinder hole to open the door lock and see if it is smooth and flexible. Whether the force is light and whether the sound is crisp and pleasant.

The fourth factor to consider is the firmness of the lock. The lateral static tension of the handle is an important indicator of the lock's firmness. An excellent lock should ensure that the handle remains straight and does not sag even after being opened and closed millions of times.
