Before choosing a smart lock,we will measure the size of the lock body firstly.
As smart home gradually enter our lives, smart door locks have begun to become a hot item in our lives. However, due to the large number of smart door locks on the market currently, many people do not how to choose suitable locks. So we need to have a full understanding of smart locks, especially the lock body part of smart locks, which is the most important thing.
The current smart lock body can be divided into national standard lock body and non-national standard lock body. The material of the lock body is preferably 304 stainless steel, which is more durable, strong and reliable, resistant to wear and not easy to rust. If the iron sheet, zinc alloy, or ordinary alloy of poor quality is selected, it is easy to rust and mold, and the durability is poor too.
When smart locks are produced, in addition to meeting national standards, they must also comply with the actual situation of domestic anti-theft doors. There are relatively strict size standards. The size of fingerprint locks usually refers to the standard size technical indicators of fingerprint locks. The lock body is divided into a normal lock body and a large lock body, which have different size requirements and must meet the actual installation and use scenarios.
Generally speaking, the thickness of ordinary anti-theft doors is between 40mm and 60mm, which is also the thickness of common fingerprint locks. Therefore, the lock body needs to adapt to this size, and the common sizes are: 50*45/50; 58*45/50; 72*45/50/55/60; 85*30/35/45/50/55/60; 92*20/25/30/35/40 and so on.
When measuring, we can calculate the distance from the empty center point of the handle to the center point of the keyhole, and then measure the distance from the center point of the handle to the edge of the door, that is, the depth of the hole on the door is measured to the center point of the handle. Distance, these two distances are the specifications of the lock body, and also pay attention to measure the depth and length of the hole on the door, so that the lock body can be completely matched.
In addition, everyone should pay attention to one point: the cylindrical lock body is mainly used for stainless steel anti-theft doors, and the square lock body is mainly used for wooden doors. It is recommended that you purchase standard and Bawang cylinder and square lock bodies when purchasing the lock body inventory. When installing the smart lock, you should mainly measure the size of the lock body, and try not to exceed the outer panel size, otherwise the cover will not be removed. Traces of the lock.
