How do you know if the lock is bad?
Jun 28, 2018

一. Common malfunction and removal of padlock

Padlock is the most widely used in daily life because the parts are closed in the lock body and need not be installed when they are used. For a long period of time, outdoor locks will show faults such as lock core, locking beam and so on.


1. Do not lock the core


The failure of the lock core often appears in the lock which is not often opened outside the door for a long time. The padlock was exposed to wind and rain for a long time, and rust and dirt accumulated between the lock core and the lock body, so that the lock core could not be turned. Before the failure is eliminated, the key of the check is whether the key is the key. If there is no doubt, it will be removed again.


The way to get rid of it is to put in a small amount of diesel or fuel. If you can not turn on, then take part in diesel or fuel, during the bubble period, use the key to gently move back and forth until all the cut-off. Avoid too much strength and turn the key off.


Additional, there is also a phenomenon of failure to lock the heart because of the destruction of the key tartar. At this point, we should carefully search for the destruction of dental calculus. If the damage is small, it can still be unlocked after repair. If the damage is large, we should find other spare keys to unlock.


2. Inflexible key inserting

The use of the key is not very flexible for a long time. You can cast some graphite face in the keyhole, {green ash}, then switch several times. To avoid participating in the lubricating oil in the keyhole, it will affect the marble activity and expose the open failure.


3. The lock beam does not jump

Most of the failure of the lock beam is caused by too large tolerance of the lock beam and position, and one side of the lock beam and the lock beam hole is exposed and squeezed.


The way to get rid of it is to insert the key into the lock core, turn it to the open position, and gently hammer down the lock body with a small hammer or pull down the lock body with force. If the earthquake does not open, you can add a small amount of fuel or diesel oil to the lock beam and gently beat it until the lock beam leapt out. After the lock beam jumps out, use the soft hammer to correct the lock beam and repair it and continue to use it.


4. The key is broken into the lock body

The failure of the key into the lock body occurs more frequently, and the way to get rid of it depends on the situation.


(1) the key is broken into the lock body from the root and a section is set at the lock chest. You can use small tweezers or pinch pliers.


(2) the key is broken into the lock core from the part, and it can not be activated. This kind of situation is only dismantling the seal seal on the lock body, taking the bullet out of the lock and the broken key, and then putting the lock, the bullet and so on, and sealing it with the aluminum wire.


二, common fault and discarding method of bucket lock


1, the key insert is flexible and unplugged. This end is driven by the variant of the pin, which leads to the large axial gap of the lock center, and the dislocation of the round head and the hole of the lock head is reset, and the plug is reset when the plug is inserted, so the plug is not flexible. The way out is to remove the lock, adjust the pin or pad to eliminate the gap.


2. The opening of the ten opening of the bucket is flexible, and the opening resistance increases when the bucket is pushed in. This is caused by the installation failure, the chisel groove of the upper beam of the bucket is chiseled too close, the lock tongue scrapes the tongue slot edge, so that the opening resistance increases. As long as it is repaired, the upper part of the upper beam can be removed.


3. The long time application of the key is not flexible. Like a lock, it can be like graphite pens, {ash} or candles in the keyhole.


三. Common failures and elimination methods of tongue bullet lock


1. The key and knob are not flexible when the door is locked. The end of the lock box is provided with a display between the lock box and the lock body, and the scraping edge or the door plate is changed, so that the frictional resistance on the edge of the locking box and the tongue is enlarged. Can be settled through the position of the debug lock box 


2, the lack of "inside insurance" function. The malfunction is caused by the key dialing device. The key should be pointed to the lock tongue when installing the key dial. The discarding method is from the new installation.


3, the locking heart is not flexible. Because of the large temperature difference between the inside and outside of the gate in winter, the phenomenon of rust appeared on the lock core, which leads to the inflexible rotation of the lock core. You can put candles or graphite powder on the key, insert the lock core to turn it off, and increase the lubricating oil of the lock core and the lock body. It is not allowed to add oil to the key tartar or lock to prevent the elastic force of the spring.
