In the process of purchasing smart door locks, the customer service of merchants generally asks to provide the guide plate size of the existing door locks at home. Why?
Let’s first understand what a guide film is.
The guide piece is an iron piece or stainless steel piece fixed in the telescopic position of the lock tongue, and it is one of the essential parts in the installation process of the smart door lock. There will be bolt holes and fixing screw holes matching the lock body on the guide plate, so generally speaking, the size information of the guide plate is collected in a disguised form.
What is the function of the guide vane?
In fact, the main function of the guide piece is to protect the door frame. In the process of frequently opening and closing the door, it is bound to cause a certain degree of wear on the door frame, and it will play a certain buffering role after installing the guide piece, so the smart lock will be equipped with the guide piece as standard.
Why do you have to provide the guide plate size of the original door lock?
Because the size of the guide plate is not fixed and unified, users need to accurately measure the size of the guide plate at home during the purchase of smart locks. Before the measurement, the types of the guide plate should be determined. The common types are: right-angle single hole, right-angle double hole, rounded single hole and rounded double hole. After the determination, the length, width and door thickness of the guide plate should be measured continuously.
Generally, there are four kinds of commonly used guide pieces: 24*240mm, 30*240mm, 30*388mm and 40*388mm, which can basically adapt to most domestic security doors.
Of course, in addition to accurately measuring the data of the guide vane, it is also necessary to confirm whether there is a hook between heaven and earth, whether the gap between the mother door and the child door will affect the use of the smart lock, the direction of opening the door and other information to ensure the adaptability of the smart lock.
