In an interview with the security door market on July 6, a reporter found that many citizens do not understand what a good security door is. When buying security doors, they often only pay attention to the appearance of the door and the steel plate, but ignore the security door. "Heart"-locks, and most of the dealers did not mention the locks to reporters when they promoted their products, but just emphasized how thick the door's steel plate is and how the price is favorable, without reminding customers of locks. If the lock is not closed, the customer may buy a security door that is obvious but not anti-theft.

Dealers are vague, most people buy the door without asking the lock

In some stores that specialize in anti-theft doors, the reporter found that when many consumers choose anti-theft doors of different styles and patterns, they generally turn the doorknob and knock on the steel plate. Some will ask about the thickness of the steel plate, The installation situation has neglected the core of the anti-theft door-the lock. A consumer surnamed Li told reporters that he believes that a thick steel plate and a stylish and luxurious security door are good. Citizen Miss Liu said that the anti-theft door and entry door of the new house are all purchased by the developer, and they do not know the security performance of the anti-theft door at home.

Because consumers do not pay much attention to the safety performance of door locks, many dealers do not explain locks when they sell anti-theft doors, let alone introduce some professional knowledge about locks. In some stores, many distributors see consumers come to the door, the first introduction is the style and workmanship of the anti-theft door, and rarely mention the lock and level of the anti-theft door. When the reporter asked about the security performance of the anti-theft door, and whether there was a security technology issued by the public security department to prevent product permits, some dealers said that their anti-theft door has multiple lock points such as "world lock", as well as lock edges The quality is excellent, and it will certainly not be easily opened. Some have taken out the manufacturer's ISO series certification, and some have indicated that the anti-theft door has 100,000 yuan quality insurance. When the reporter asked whether the security level of the lock was A-level or B-level, some dealers responded that the locks sold in their stores were AB locks. During the decoration, the workers used the A key to open the door. After the decoration, As long as the owner inserts the B key into the lock hole, the A key is scrapped.

The key to anti-theft lies in the lock

An industry source told reporters that there are currently dozens of anti-theft doors sold in the Huizhou market, ranging from some domestic famous brands to small local brands, with prices ranging from more than 700 yuan to several thousand yuan, but some anti-theft door locks Not at all anti-theft. According to reports, the two basic components of an anti-theft door are the door and the anti-theft lock. "The door lock is an important part of the anti-theft door. If the quality of the door lock is not close enough, even the best anti-theft door can't fully play the anti-theft function." A well-known brand anti-theft door dealer told reporters. According to the "GA / T73-94 Mechanical Anti-Theft Lock" promulgated by the Ministry of Public Security, mechanical anti-theft door locks are divided into ordinary protection levels and high protection levels, which are expressed as A level and B level respectively. A-level lock anti-technical opening is not less than 1 minute, anti-destructive opening is not less than 15 minutes; B-level lock anti-technical opening is not less than 5 minutes, anti-destructive opening is not less than 30 minutes. However, the vast majority of anti-theft door locks on the market are locks of ordinary protection level. Some merchants say that there are many lock points on their anti-theft doors, and no one can open them. In fact, they are confusing the concept of lock points and lock cores. The lock point is the point where the door and the wall are connected together, and it has an anti-pry function. 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.

Pay attention to requesting "Inspection Report"

So how can you buy a good security door? This person in the industry reminded the public that when buying anti-theft doors, they should choose big brands with good reputation as much as possible. The lock is still a Class B lock and pay attention to check the following:

Qualification certificate: The real anti-theft door must be qualified by the statutory testing agency according to the standard, and have the safety technology prevention product approval production certificate issued by the safety technology prevention department of the provincial public security department (bureau) where the production enterprise is located.

Lock: the core part. Qualified anti-theft doors generally use three-position locks. Not only the door lock is locked, but the upper and lower cross bars can be inserted into the lock to fix the door. Inferior products generally do not have three-point locking or optional three-point locking structure, and do not have anti-theft function or often fail.

Process quality: Special attention should be paid to check for welding defects, such as open welding, unwelded, missing welding, slag inclusion, etc.
