Tiandi hook, a word that must be paid attention to when installing smart
locks. It is more common in household anti-burglary doors, and the reason is simple: it looks safe. So why do many smart locks installed by households for safety reasons clearly indicate that they do not support Tiandi Hook during installation, and why many smart lock installers say it is best to remove the Tiandi Hook? What impact does Tiandi Hook have on safety? What is heaven and earth hook? Speaking of heaven and earth hook, let's first understand its principle and function. Ordinary locks will pop out the main bolt on the side of the door. On this basis, the heaven and earth hook increases the number of bolts that can be ejected above and below the door, so that the door can be more firmly fixed on the door frame. The extra bolts are upwards and downwards, hence the name 'Heaven and Earth Hook'. The function of the heaven and earth hook is also very simple and clear. By adding lock points, the door can be prevented from being violently opened, and safety can be increased. Why is heaven and earth hook unnecessary? The Heaven and Earth Hook resists the risk of the door being pried open under 'violent' situations, but it does not defend against technical unlocking. From what we have learned, the vast majority of domestic thefts are unlocked by technology, that is, unlocking and entering the room by simulating the situation of opening the door with the correct key. Why is it recommended to remove the heaven and earth hook when installing a smart lock? When installing the smart lock, the master suggested to remove the heaven and earth hook. However, the lock body of this smart lock supports the heaven and earth hook, but the master did not install the heaven and earth hook. Instead, it took time and effort to remove the heaven and earth hook. Distressed and less sense of security. For smart locks that support the driving of the heaven and earth hooks, these smart locks mostly use the force of the human hand to drive the bolt. The smart lock body needs to bear more resistance, especially on some
door locks that have been in disrepair, which can be intuitively reflected in the following The force required to press the handle is very large, and excessive weight can easily cause damage to the internal structure of the smart lock body. After all, the internal structure is much more complicated than traditional mechanical locks. How to judge whether there is a heaven and earth hook and many automatic smart locks need to directly drive the bolt through the internal motor of the lock body, which has a relatively large load. If the heaven and earth hook is added, not only a stronger motor is required, but also more Power. Therefore, many automatic smart locks have cancelled the support of Tiandi Hook. Therefore, for modern families, Tiandi Hook is really not that important. As for why the smart lock was removed when it was replaced, it must be because I didn't bother to change it before changing the lock.
