What should I do if the security door is not closed tightly? What should I do if there is a gap in t

1. Door frame and door.

The interface of the fan is pasted with a leather strip, you can see if the leather strip is not there, if you don't have it, you can buy it where you can sell the anti-theft door, and install a D-shaped rubber strip on the part where the door frame collides with the door, which can effectively prevent wind and dust, and secondly, you can also reduce this kind of sound.

2. If the door closes loudly, the hinge can be adjusted.

Or find the impact and knock it flat with a hammer.

3. The lock is oxidized due to long-term use, and the collision between the deadbolt and the keyhole, so the solid lubricating oil can be applied to the deadbolt.

After using it for a period of time, it was found that the door was not closed tightly.

After using it for a period of time, you can adjust the door closer if you find that the door starts to close tightly. It can be adjusted above the door by tightening and loosening the valve screws. However, it is necessary to pay attention not to change the fluctuations too much when adjusting, and adjust them appropriately little by little, and turn the door leaf after adjustment to see if it can be closed tightly.

If you find that it has nothing to do with the tightness of the door closer after adjusting it, then there is a problem with the fit of the part. You can see if there is any obstruction on the door and hinge that prevents the two from fitting perfectly. If there is one, it will hinder the removal, and then apply some lube on it.

You can also use some instruments to see if the door is deformed. Some doors have been used for a long time, and there may be some degree of deformation with the vigorous closing. If you still contact the brand's after-sales service during the after-sales warranty time, if the after-sales warranty time is exceeded and the asking price is higher, you can use the sealing strip to increase the fit.

Adjust the position of the metal plate of the keyhole on the door frame.

The security door is not closed tightly, it is likely that there is a large gap between the deadbolt and the door frame, this situation can buy some seals, around the security door sticky a circle, generally there will be no clanging sound, if the deadbolt position is not correct, or the reserved position is too large, it will also lead to noise, the keyhole metal position on the door frame can be adjusted to the appropriate situation.

Even if there is a reserved rubber strip on the door frame itself, because the product quality is not good, it hardens or shrinks after a long period of use. In this case, only the hardened or shrunken rubber strip needs to be removed, and then the rubber and plastic strip or adhesive wool strip are replaced.

It should be noted that the installation of the anti-theft door should be in accordance with the type of anti-theft door adopted, and the appropriate installation method should be adopted, and the door frame of the anti-theft door can be fixed with the wall by expansion bolts, and the iron parts can also be embedded at the opening when the wall is built, and the door frame connector is welded firmly during installation.

It should be noted that no matter what kind of connection method is used between the door frame and the wall, there should be no less than 3 anchorage points on each side, and they should be firmly connected, and the gap between the door frame and the ground plane should not be greater than 5mm. Anti-theft device should be installed between the door frame and the door leaf or other parts, when installing the anti-theft door, it should be straightened and hung first, and it should be temporarily fixed after the appropriate size, and corrected and adjusted, and the connection anchorage can be carried out only after the error.

There are three reasons for this:

1. The position of the door is sagging

After the door has been used for a long time, there will be a phenomenon of sagging, which will cause the deadbolt of the door lock to not match the door lock box (the deadbolt hole of the door frame), resulting in the difficulty of the deadbolt to protrude, and even the phenomenon that the door cannot be locked.

Solution: Use a file to rub the lower edge of the door lock plate and the edge near the outside of the door, a little careful, which lock tongue can not be stretched out on which lock plate, generally will be done.

2. There is a problem with the deadbolt

It may be that there is a problem with the deadbolt, in the state of the door open, test the deadbolt that cannot be stretched out with your hand to see if it is laborious, if it is not laborious, it is not a problem with the lock, if it is laborious, it is! This usually happens when the lock has been used for a long time.

Solution: Replace the lock body, strong hands-on ability, go to the almighty treasure, weak hands-on ability, or unwilling to do it, find a professional, remember to match the model, otherwise it is easy to install.

3. There is a problem with the gap between the deadbolt and the door frame

Because of the use of too long, resulting in the gap between the deadbolt and the door frame, there is a problem, mainly the oblique tongue, which is generally manifested as gently closing the door can not be closed, and it can be closed with a little force.

Solution: Adjust the locking plate or change the usage habits.

Security door maintenance tips

The tightness of the expansion bolts used in the installation of the door frame and 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 every three months to avoid the door sagging after the screws are loosened, so that it is difficult to open the door due to friction with the door frame. In addition, the screws on the lock plate and handle should be reinforced regularly, but never remove the lock without permission. Consumers are not professionals, and it is inevitable that there will be gaps, errors or poor coordination of parts after the lock is removed and then installed, which may directly lead to the failure of the safety door lock and other problems.

In addition, the pencil end lubrication should be added to the cylinder regularly to make the key insert and unplugging smoother, but it should not be lubricated with grease. If grease is dripped into the hole, it will mix with the iron filings caused by the key rubbing inside the cylinder, and the entire cylinder will be blocked within a month.
