People's understanding of locks is relatively superficial. When encountering some small lock problems, they will find professional unlockers to solve them. As for the difficulty of unlocking or the maintenance of the lock, I will teach you how to maintain the lock today.
First, what locks are easily destroyed
1. The lock of the iron roll door - easy to be destroyed.
2. The general ordinary padlock comb tool --- easy to be cut, knocked.
3. The general lap lock - easy to be destroyed, violently turned away.
4. Auxiliary lock (the kind of conical protruding door panel) --- easy to be broken.
5. The electric iron door switch box lock installed outside the door - easy to be opened.
6. The three-stage lock-separated lock---easy to be turned away by violence. (When the lock is locked, keep in mind that the locksmith is not lazy and does not fix the lock plate.)
7. The lock core (where the key is inserted) is constructed of copper (such as a steam locomotive lock) - more fragile and easily destroyed
8. Motorcycle locks - easy to be violently spoiled.
9. The locomotive tire lock of the lower grade is easy to be cut. Think about bargains to help you look at the car?
10. Drawer locks are easily destroyed - don't put expensive things.
11. General aluminum door locks - because the lock structure is very fragile and easily destroyed.
Second, how to maintain the lock 1. Lock the heart not to rain. Flush, because there is a small spring inside will rust failure is not flexible.
2. The locomotive keys don't have a big string, they are connected in series. When the locomotive is running, the key shakes and the weight will wear the lock, and the key will slide out.
3. When the key is not inserted or pulled out, spray some light lubricating oil. (such as w40) The oil that is not too strong will not move.
4. Some locks can't be refueled, and (very few) are like the mother's beads.
5. When the door lock is not good, switch some lubricant on the oblique tongue.
6. Automatic lock (three paragraphs. Four sections. Five sections) Some micro-gap should not be too tight. (If you need to push the door with your hand to unlock when unlocking) The lock is easy to break.
7. The door joints should not be too large and can be easily opened and shaken.
8. The security door has a lattice type, which prevents the wire from being pulled into the oblique lock handle of the automatic lock, and pulls the door open.
9. Do not use the key to open the door directly. The key turns the door lock. If the lock is not returned, the key will be opened directly. The lock will not be long before you will protest and say goodbye.
Third, anti-lock, people are locked by themselves, there is a key to open
1. The horn lock will be locked. When the person is locked in the room, it can't get in or get in. It can't be opened with the key. It is the slanting tongue lock and the hook is unhooked. The grip can not be driven by the slanting tongue:
â—ŽWhen people are inside: find a small wire or --- there is a small hole in the neck of the grip, insert the flat card grip inside and pull it out at the same time, grasp the handle and open the cover, there are two Fix the screw idea and turn it away. When the lock body is pushed out and only the oblique tongue is left, find a needle-nosed pliers or a flat-nose screwdriver. Move the oblique tongue to the horizontal dial and don't let go. After you let go, you will bounce back and push the door open. . You're done!
â—Ž When people are outside: Find a tongs pliers or water pipe clamp, hold the ram lock grip and twist it hard, grasp the lock and turn the cover left, and then knock the lock body out (because it cannot be pulled out, The lock body is caught by the inner cover. You can see the oblique tongue. Then find a needle-nosed pliers or a flat-nose screwdriver. Move the oblique tongue to the horizontal dial and don't let go. After you let go, you will bounce back and push the door open. You're done! !
☆This method can be used in case of emergency. ☆ It is recommended to find a locksmith for the lock.
2. The three-stage lock is forced to close because the anti-lock twist is not twisted. At this time, there is a key that can't be opened. Only the locksmith can be handled----Nothing? That only the climbing window enters-----breaks the glass-- --Saw iron railings?-----o
4. Automatic lock, the child will not lock in the inside lock (mostly 2-4 years old children like to play anti-lock twist), at this time you don't yell, but will scare the child, slowly induce him to open the door, induce him to reverse When the hour hand turns away (if you stand outside the door, facing the door, it is turning to your right hand side). If it is a five-stage lock, some are pulled up and down, and the downward pull is --- open.
5. The car is most likely to be locked, the sensor is faulty or you accidentally press the lock, close the door and be locked - at this time, it is best to ask the locksmith to help, and the hook may be hooked off the rod or wire, various The structure of the car is different, and it is easy to cause much damage or the hook is hooked.
Fourth, the door, the lock suddenly can not open
1. When the violence is closed, (mostly the gusts are blown off by the gusts). The horn latch is easy to get rid of the hook, or the door is twisted or the bolts are loose and protruding, and the door frame cannot be opened.
a. If it is a horn lock, please see "What to do if you lock it".
b. In the case of auxiliary locks, (mostly installed in iron doors, copper doors), the locking tongue or the handle of the handle tongue is loose and protruding, and the door frame cannot be opened. (Look for a flat-blade screwdriver, and push the protruding screw from the door to the inside to dial back).
2. When the foreign object is stuck, the handle or the key is difficult to twist. (Please make sure that the door is open inside or open outside to stand inside, open outside - the door pulls inwardly, and the door pushes outward when the door is open. When the person stands outside, the outside opens---the door is forced to Inward push, the door is pulled out when the door is opened. It can reduce the card force and easily open the door).
3. When the locksmith comes to unlock the lock, he said that the lock is broken and can't be opened. Do you believe it? At this point, you can find another one to open and see. I often encounter the lock open, the main talent tells me to open the second hand, and the surprise is opened so quickly, the last one can not open for a long time, said If the lock is broken, it can't be opened. It has to be replaced with a new one (a good lock, maintenance and normal use, no problem for ten years). Some lock stores will not open the excuse, ask for a new one, some are technology. Some problems, some do not want to spend too much time to unlock. (It is best to find a fixed, reliable credit lock service)
Also, usually the lock cylinder is used for a long time, and the surface is easy to leave an oxide layer, so that the more the product is accumulated, the less the spoon will appear. In this case, the Beijing unlock master teaches you to apply some lubrication inside. Oil, graphite powder or pencil powder to help eliminate the oxide layer, to achieve smooth opening and unlocking.
