In the early days, in order to increase the safety factor, the anti-theft door had the design of heaven and earth hook. By adding two sets of locking tongues, the door and the door frame were connected more closely, which made users feel more secure. However, as the technology of unlocking becomes more and more mature, criminals can easily open the door lock by simulating the unlocking process, while the hook of heaven and earth can only be used to prevent violent unlocking. As early as 17 years ago, Changsha Evening News published a set of public security statistics: among all kinds of burglary, card unlocking accounted for 80%, technical unlocking accounted for nearly 15%, while burglary from windows accounted for nearly 5%, and violent unlocking accounted for less than 1%. The hook between heaven and earth is useless.
Although the hook between heaven and earth is not necessary at present, some users said that it is good to have an extra layer of protection. But it ignores the risks it brings. In case of fire, when the security door is deformed due to the influence of temperature and cannot be opened, the hook between heaven and earth will make it more difficult for firefighters to break into the house, thus delaying the rescue opportunity. Although the probability of this event is low, the result caused by this risk is something that everyone does not want to see. Therefore, Xiaobian still recommends not installing a hook.
The picture comes from the Internet.
Moreover, at present, smart locks are mature, and there are mature designs in anti-prying, which protect the safety of users from both electronic and mechanical functions. Take Younger Smart Lock as an example. In the production process, every front-end quality control link from raw materials has strict standards. Every lock produced must pass the inspection, and after nearly 100 inspection procedures, the qualified smart lock products can be packaged before leaving the factory.
Electronic functions are dustproof, moisture-proof and anti-magnetic field interference, and the small black box transmitted by the network can’t be unlocked. In the aspect of mechanical unlocking, the C-class lock core is used to increase the difficulty of picking locks. In addition, for technical unlocking, Younger also has square bar anti-pinch design, cat’s eye anti-lock technology, hidden hole design, quadruple anti-pry alarm and other aspects to protect the safety of users, which can basically meet the safety of users.
If the user still wants to install the hook, the smart door lock can also meet the requirements, but the following situations may occur:
1. High power consumption
As an electronic product, the smart lock is driven by the internal circuit, but the lock needs more driving force to drive the hook, so it consumes more power.
2, improve the failure rate
The increase in the number of hook parts and the complex structure will not improve the safety, but will increase the failure rate of door locks. However, the installation of the heaven and earth hook is difficult. If the master is slightly improper in installation, the lock body will easily get stuck, which will affect the access of users.
3, damage the life of the smart door lock
Due to the increase of locking tongue, the force on the lock body is multiplied, and the transmission of the whole door lock will have a great burden, and long-term loss will weaken the patience.
Finally, Xiao Bian still thinks that the hook between heaven and earth is unnecessary or not. It is too troublesome to have problems from time to time. If you still want a hook between heaven and earth, you must choose a smart lock of a big brand. With good after-sales service, you can be more secure!
