According to the principle of lock core, anti-theft door locks can be divided into pin locks, blade locks, magnetic locks, ic card locks, fingerprint locks and so on.
First, the anti-theft door lock installation steps
1. According to the installation size of the lock body,
Location of mounting hole of drilling lock body. 2. Install the lock body into the hole position in turn, align the rear fixing screws, install the screws and connecting screws on the outer plate, insert the interlocking square bar into the square bar hole of the lock body, align the square bar hole of the outer plate with the interlocking square bar hole, and install the outer plate.
3. Install the inner plate components and align the rear fastening screws; Insert the lock body into the lock hole of the lock body from the inside out; Insert the screw from the lock body panel hole, align with the thread of the lock body mounting hole, and then tighten it. Then install the lock box or lock plate on the door frame.
4. After the initial installation, turn the outer handle and the inner handle to observe whether the oblique tongue can be retracted smoothly; Turn the knob on the back panel to feel whether the square tongue retracts smoothly; Insert the key and rotate it back and forth to feel whether the square tongue extends and retracts smoothly.
5. After tightening the assembly screws, repeat the above actions and try several times. If the movement is not smooth, please loosen the screw, adjust the position and try again.
Until it fits. Second, the anti-theft door lock troubleshooting
1, the key is inflexibility. The key is not flexible after being used for a long time. You can sprinkle some pencil powder {graphite} in the keyhole and turn it on and off several times. Never oil and lubricate the keyhole, which will affect the marble activity and cause accidental opening failure.
2, anti-theft lock beam does not jump. The failure of locking beam not jumping is mostly caused by the excessive tolerance of the shape and position of locking beam.
The lock beam and one side of the lock beam hole are scraped and squeezed, and the lock beam cannot jump because of corrosion and fouling. Troubleshooting: Insert the key into the lock cylinder, turn it to the open position, knock down the lock body lightly with a small hammer or pull down the lock body forcibly. If the shock does not open, you can add a little gasoline or diesel oil 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, and it can be used again after repair.
3. Insert the key into the lock body
Failure of key breaking into lock body occurs from time to time, and the elimination method depends on the breaking situation.
(1) The key breaks into the lock body from the root, leaving a section at the lock core. You can use tweezers or needle-nosed pliers and other tools to clip it out.
⑵ The key enters the lock core from the middle and cannot be shaken out. In this case, just remove the seven-hole seal on the lock body, shake out the marble, and take out the lock core and the broken key together.
Then reinstall the lock core, marbles, etc. And sealed with aluminum wire. Third, replace the lock core of the security door.
1. Open the inner plate rivet with a flat chisel;
2. Open three connecting shafts (three spring bolts and three gaskets) of the linkage mechanism respectively; Be careful not to lose parts;
3. Remove three screws (triangular arrangement, with the lower two inside) for fixing the linkage mechanism, and take out the whole linkage mechanism;
4. Take out the outer panel;
5. Dismantle the lock cylinder: remove the bayonet spring, remove the control lever and unscrew two screws;
6. Reinstall the lock cylinder: contrary to the operation in step 5;
7. Reinstall the outer plate: If the core hole of the outer plate is too small for the key to pass through, it needs to be reamed (the original magnetic key is much smaller than the toothed key).
8. Reinstall the linkage mechanism;
9. Debugging: You may find that the plunger sticks out more, leading to many inexplicable failures. You can loosen the fixed screw of the linkage mechanism properly, keep the door lock open and closed, observe the collision interference position, and adjust the protrusion of the gear lever or other parts appropriately;
10. Replace the inner panel with a rivet gun.
Fourth, the maintenance method of the family lock
Maintenance methods of household locks 1:
After opening the door, most friends will always push the door against the door frame and give it a locked hug. However, this is not what the door wants. After opening the door, turn the handle to retract the lock tongue of the door, then combine the door frame and release it. In short, it is necessary to avoid the serious collision of door locks, otherwise it will shorten the service life.
Maintenance method 2 of household lock:
When we open or close the door, the lock body often rotates towards it, and over time it becomes less flexible. Therefore, we need to ensure that there is lubricant in the rotating part of the lock body, which can reduce the friction of the lock body itself, thus increasing the service life of the lock itself, and in order to ensure the safety of the lock, we'd better always check whether the lock nail is loose.
Family lock maintenance method 3:
In addition to the lock body, we often turn, and the lock core is also the place where we often contact. After a long time, the key will not be smooth in the process of pulling and inserting. So we need to add some things that can lubricate the lock core. Of course, the lock core must not be added with lubricant or some oil substances. So we'd better choose to add some graphite powder, that is, pencil powder, which can play the best lubrication role for the lock core.
Family lock maintenance method 4:
In addition to the above maintenance methods, it is also necessary to regularly check the fit clearance between the lock body and the lock plate, the high-low fit between the lock tongue and the lock plate, and the gap between the door and the door frame. If these are not properly matched, it is necessary to make appropriate adjustments, otherwise there will be certain security risks and even shorten the service life of the lock.
Maintenance method 5 of household lock:
Some friends often like to drop some lubricating oil into the lock hole when the lock is rough or locked. In this way, the lock may be smooth soon, but because the oil is easy to stick to dust, it will easily accumulate dust in the keyhole in the future, which will make the lock more likely to fail. So, don't add lubricant to the keyhole unless necessary. You can cut some pencil scraps or some candle scraps, blow them into the lock core through a thin tube, then insert the key and turn it several times.
Family lock maintenance method 6:
Sometimes, due to the gravity of the door leaf or the loose leaf of the brake, the door leaf sinks and the door cannot be locked or opened smoothly. At this time, it is often very difficult to open and lock the door with a key. At this point, don't twist the key hard, so as not to break the key and increase the trouble. You should check the reason first. If the door leaf sinks due to loose loose loose leaves, the loose loose leaves should be fixed firmly with screws. If the door frame is deformed or unrecoverable due to its reasons, we can start with the door frame and expand the lock tongue accordingly, so that the door lock can be opened and closed normally and smoothly.
