Security door maintenance has the trouble that home can't get in!

The full name of anti-theft door is "anti-theft safety door", which has both anti-theft and safety performance. Its biggest characteristics are strong security, durability, flexible opening and beautiful appearance. Let's take a look at the common problems and maintenance of security doors.

A complete collection of maintenance methods for anti-theft doors

First, my security door is dirty and ugly. What should I do?

According to Bian Xiao's years of experience, when the door is dirty, the best cleaning method is to mix 70% water with 30% cleaning solution, put it in a sprayer, spray it evenly on the door surface, and then wipe it gently with a soft cloth.

Second, when the door is opened and closed, there is a metal friction sound, which is very noisy. What should I do?

Parents can try to drop a little lubricating oil on the door hinge when there is a metal friction sound on the door and they are too lazy to find a maintenance person to repair it.

Third, it takes so much effort to close a door. The resistance of this door is too great. What should I do?

Sometimes when the door is closed, the resistance is too large, so parents don't have to worry about it. As long as a little lubricating oil is applied to the movable locking tongue, it can be easily solved.

What is this? Why can't my key fit in the lock?

Sometimes parents may encounter the situation that the key cannot be completely inserted into the keyhole when opening the door. In the winter when I went to the north for inspection, parents should first check whether there is ice in the keyhole, and in other seasons, they should also check whether there are other foreign objects in the keyhole. If you really can't do it, don't play hardball. You'd better find a maintenance man.

5. What if I can't lock the second lock when I lock the door?

Bian Xiao neighbor's security door also had a little problem a while ago. In the process of using the security door, due to the excessive impact force when opening and closing the door, the door frame may be dislocated and the lock tongue may be stuck. Don't worry! If it is the right key, it can be inserted into the lock hole normally, and you can try to blow pen foam into the lock core. Push the door hard, or pull the door.

6. I entered a house and locked it for a long time. What happened?

Honey, if you find it difficult to open the door, don't be grumpy and don't push too hard, which will only break your lock. In this case, the small locking tongue on the inclined plane is usually wet! It has produced rust spots that are not easy to see with the naked eye! It can be easily solved by wiping it with a fine sand cloth or wiping some pencil scraps.

Maintenance of security door:

Maintenance of lock: When the lock head is in use, Jamlom graphite powder or pencil powder can be applied to the lock core groove periodically (half a year or one year) or when the key is not inserted smoothly, so as to ensure the smooth key insertion. However, it is forbidden to add any other oil for lubrication, so as to avoid the grease sticking to the marble spring, which will make the lock unable to turn and open. Always check the fit clearance between lock body and lock plate, whether the height of lock tongue and lock plate hole is appropriate, and the best fit clearance between security door and door frame is1.5mm-2.5mm. If there is any change, adjust the position of door hinge or lock plate. At the same time, pay attention to the weather (wet in spring and dry in winter), so as to ensure that the gap between the safety door and the door frame, lock body and lock plate is reasonable and ensure the smooth use of the lock. Do not insert sundries or inject engine oil into the keyhole of the security door lock to avoid gambling jam. When the lock is not flexible, you can lubricate it slightly (not too much) with pencil powder. The inflexibility of the lock affects seeking professional help when opening the lock.

Maintenance of the facade: often wipe the facade with a soft cloth to keep it clean, which can prevent the corrosion of corrosive substances and increase the glory of the security door. If you encounter tape stains, Dragon Tree Bian Xiao suggests that you add a little mixture of ammonia and turpentine with soap to remove a lot of dirt and make the glass surface more shiny; Repeated tearing with transparent adhesive with good viscosity can remove part of the surface; Wipe it off with a little sodium hydroxide, or use paint thinner; You can dry it with a hair dryer and then scrape it gently; Wipe with cotton swab dipped in nail polish remover; ? Wipe with wind oil essence; Wipe with special cleaner or sports shoes decontamination cream; You can erase it with 4b eraser for painting, which is a very soft Korean eraser. If the trace has hardened for a long time, you can soften it with a hot towel and try again. Regular reinforcement of all parts of the security door: regularly add a little grease to the mechanical rotating parts of the security door, such as hinges, bolts and bolts, to keep lubrication and keep the security door and its locks open and close flexibly. The fastening degree of the expansion bolt for door frame installation with the wall and door frame should be checked regularly to avoid potential safety hazards. The screws on the hinges of the door body should be reinforced once every three months, so as to avoid the looseness of the screws and the sagging of the back door body, and the friction with the door frame will make it difficult to open the door. In addition, the screws on the lock plate and handle should be reinforced regularly, but never disassemble the lock without permission. Consumers are not professionals. Cracks, mistakes or poor matching of parts will inevitably occur after unlocking and locking, which will directly lead to the failure of safety door locks. In addition, the lock core should be lubricated with pencil powder regularly, which can make the key insertion and removal smoother, but don't lubricate it with grease. If the grease is dripped into the lock hole, it will be mixed with the iron filings generated by the friction of the key in the lock core, and the whole lock core will be blocked within one month. Having said that, I think everyone has a certain understanding and mastery of the maintenance of security doors. Security door maintenance method? Bian Xiao personally thinks that maintenance is not as good as quantity and maintenance. The most important thing is to attach importance to the brand quality of the security door itself and the daily maintenance of the security door by the family.
