一、 Common faults and troubleshooting methods of padlocks Padlocks are used most often in daily life. Because the parts are enclosed in the lock body and do not need to be installed during use, failures are rare. Padlocks that have been used outdoors for a long time will have failures such as lock core and lock beam not jumping.
1. The lock core does not turn. The failure of the lock core not to turn often occurs in a padlock that has been locked out of the door for a long time and is not frequently opened. The padlock has been exposed to wind and rain for a long time, rust and dirt accumulated between the lock core and the lock body, and the lock core cannot be rotated.
Before troubleshooting, you should carefully check whether the key you hold is the key of the lock, and then eliminate the fault after you are sure.
The elimination method is to pour in a little diesel or gasoline, wait a while, insert the key and try to open. If it cannot be opened, add some diesel or gasoline, soak it for a while, use the key to gently turn it back and forth until it is fully opened. Never use too much force to break the key. In addition, the lock core does not turn due to damage to the key teeth. At this time, you should carefully look for the damaged part of the teeth. If the damage is small, the lock can still be unlocked after repair; if the damage is large, you should find another spare key to unlock.
2. Inflexible key insertion and removal The key is not flexible when used for a long time. You can sprinkle some pencil powder {graphite} in the keyhole, and then switch it several times. Never add engine oil to the keyhole for lubrication. This will affect the movement of the marbles and cause unexpected opening failures.
3. The lock beam does not jump. The failure of the lock beam does not jump is mostly caused by the excessive tolerance of the lock beam shape and position. The lock beam and the hole of the lock beam appear scraping and squeeze, and the rust and accumulated dirt make the lock beam unable to jump. Up. Remedy: Insert the key into the lock core, turn it to the open position, and use a small hammer to gently knock the lock body down or pull the lock body forcefully. If the shock does not open, you can add a little gasoline or diesel to the lock beam, and then tap it gently until the lock beam jumps out. After the lock beam jumps out, use a soft hammer to correct the lock beam. After repairing, you can continue to use it.
4. The key breaks into the lock body. The key breaks into the lock body failure occurs frequently, and the troubleshooting method should be determined according to the break situation.
⑴ The key is broken into the lock body from the root, and a section is left in the lock hole. It can be clamped out with tweezers or needle-nose pliers.
⑵The key breaks into the lock core from the middle part and cannot be shaken out. In this case, the only way to remove the seven-hole seal on the lock body is to shake out the pin and take out the lock core and the broken key together, then re-install the lock core and the pin and seal it with aluminum wire.
2. Common faults and troubleshooting methods of drawer locks 1. Flexible when inserting the key but not flexible when pulling out. This reason is mostly caused by the deformation of the pin. The deformation of the pin causes the axial gap of the lock core to be too large. The ball and the pin hole of the lock are misaligned when being pulled out, and they are reset when being inserted, so the plugging is not flexible. The troubleshooting method is to remove the lock, adjust the pin or add a pad to eliminate the gap.
2. The drawer opens ten times to open flexibly, the opening resistance increases after the drawer is pushed in. This is a malfunction caused by the installation. During installation, the tongue groove of the upper beam of the drawer is chiseled too far in, and the tongue scrapes the edge of the tongue groove, which increases the opening resistance. Just repair the excess part of the lock tongue groove of the upper beam of the drawer.
3. The key is not flexible after long-term use. You can add pencil powder {graphite} or paraffin wax to the keyhole like a padlock.
1. Common faults and troubleshooting methods of tongue marble door locks 1. After the door is locked, the keys and knobs are not flexible to open. The reason is that the installation between the lock box and the lock body is caused by scraping or the deformation of the door panel, which increases the friction resistance on one side of the lock box and the bolt. It can be solved by adjusting the position of the lock box.
2. Lack of “outside guarantee inside” function. The malfunction is caused by the key dial installed instead {the key dial should point to the bolt when installed}. The elimination method is to reinstall.
3. The lock core cannot rotate flexibly. Due to the large temperature difference between the inside and outside of the door in winter, the lock core appears to be corroded, causing the lock core to rotate inflexibly. You can apply paraffin wax or pencil powder on the key, insert the lock core and turn it back and forth to increase the lubrication of the lock core and the lock body. It is not allowed to add engine oil to the key teeth or the lock core to avoid affecting the elasticity of the pin spring.
