Anti-theft door is door anti-theft or lock anti-theft

From wooden locks to stylish electronic locks without keyholes, people's most basic requirements for door locks are always safety and convenience. At present, most people in cities have anti-theft doors installed in their homes, but many people still have blurry functions about doors and door locks. In fact, when choosing an anti-theft door, everyone should understand that the focus of the anti-theft door is "lock" rather than "door".

â–  Various locks compete on the same stage

Mechanical lock: widely used

Yang Qiugui, a technician in a lock sales market in Xi'an, said: "At present, mechanical locks are generally used on the door, mainly with a slot-shaped opening corresponding to the lock dial on the upper part of the square tongue plate." The testing department has learned that some of the unqualified products for the anti-theft door installation of mechanical locks are mainly manifested in: the destructive opening time is too short, and the axial static pressure test of the main tongue (bolt) of the lock is not closed. In particular, some manufacturers still use single-row pin locks that are banned by the state as anti-theft door locks, and their anti-pry performance is extremely poor.

Electronic lock: easy to use "Traditional mechanical locks came into being because of poor anti-theft performance." Chief Engineer Wu Shaojun, who has studied modern locks, said: In traditional mechanical pin locks, the key The tooth pattern pushes the pin to a limited position, so that the lock cylinder rotates to remove the obstacle.

Mr. Wei, a distributor of the Xi'an Light Industry Hardware Market, explained to reporters the electronic door lock, which is generally composed of four parts: a lock body, a micro motor, a planetary reducer, and an electronic remote control. Its characteristic is that it is necessary to lock it again with a key after closing the door. You can close the door immediately to reach the "five three directions" and lock the anti-theft door at the same time; at the same time, you don't need a key when opening the door. Can be opened automatically.

Fingerprint lock: advanced technology

In the Xi'an lock market, more advanced fingerprint locks have been used in some office spaces, high-end communities and luxury villa doors.

Mr. Li Shaochun of Xi'an Langtong Technology introduced: Fingerprint lock replaces traditional keys with fingers. After the fingerprint is matched correctly, the anti-theft door is opened. The door with standard double mounting holes allows the user to complete the entire installation process with only a few screws. The lock has door magnetic alarm function, voice prompt function, etc. It can store 30 to 120 fingerprints. However, if the magnetic and fingerprint recognition parts of the fingerprint lock are destroyed, its function will weaken or even disappear.

Pure electronic anti-theft lock: subject to inspection

The reporter inadvertently found a pure electronic anti-theft lock in the market. It is said to integrate unlocking, anti-locking and alarming. There is no traditional key and only a small remote control is used. "With foreign rolling passwords, it is impossible to intercept and decipher." Mr. Zhou Hui, a dealer in a Xi'an lock city, boasted: Although this kind of lock is usually more than 1,800 yuan, no clever thief can open it! "He introduced that this kind of lock has no keyhole, and common pranksters such as sticks, wires, and glue are unable to start.

â–  If you buy a good door, you must buy a good lock

Mr. Lan, the owner of Happy Time, said: "Whether it is a wooden lock or an electronic lock, the most basic requirement for door locks is still safety and convenience. If you let outsiders use technical methods or mechanical violence, they ca n’t open it, and the owner It can be opened under normal and unexpected conditions. It would be nice if there was such a lock! "

"However, some bad businesses now boast locks without anti-theft function as anti-drilling and anti-prying" advanced locks ", and even say that the anti-theft door has many lock points, no one can open it, etc." Industry insider Wu Shaojun said: In fact, they are confusing the concept of the lock point and the lock core. The lock point is the point where the door and the wall are connected together. It has the anti-pry function, and the lock core is the core of the anti-theft lock. All anti-theft locks have only one lock core. As soon as the lock core is opened, all the lock points are opened.

Many people are still a bit vague about the relationship and importance of anti-theft doors and locks. The reporter saw in some anti-theft door sales markets and storefronts that when consumers choose anti-theft doors, they mostly look at the door style, steel plate thickness, material and appearance, etc., and think that the anti-theft door locks are "assisted" and lack Understand and value. "Actually, the door lock is the most important part of the anti-theft door. If the quality of the door lock is not close enough, no matter how good the anti-theft door can play the anti-theft function." Wang, general manager of a certain lock manufacturer definitely said.

Because some users lack awareness and attention to anti-theft door locks, they leave room for the market. Some well-known brands of anti-theft doors are equipped with locks and use high-quality products that meet the requirements of the public security department. The cost of locks accounts for about 12 to 15% of the total cost of anti-theft doors. However, in order to pursue low prices, some small anti-theft door manufacturers are equipped with low-cost and inferior door locks mostly produced by small lock manufacturers. According to reports: The quality of the steel plates of this type of locks is mostly inadequate, and the wall thickness is only 0.6 to 0.8mm, which is more than double the difference from 1.5 to 2mm prescribed by the Ministry of Public Security. Some are not steel plates at all, using inferior materials such as imitation cast iron plates or imitation steel plates, and some door locks are not qualified.

How can we achieve that “outsiders ca n’t open and the owner ca n’t stop them,” making anti-theft locks Use the fashion electronic era that truly enters a keyless hole, from passive anti-theft to active anti-theft "rejecting thieves outside the door", thus completely solving the worldwide problem that the anti-theft and lock of the lock cannot be synchronized at the same time.
