What is the anti-theft deduction anti-theft deduction installation method

If you are observing people, you will find that there are some people whose doors are open and there is still a chain hanging, or there are some things behind the doors that are buckled. This is what we have heard of the anti-theft deduction. . The following Xiao Bian came to talk to you about what is the anti-theft deduction and how to install the anti-theft deduction.

Anti-theft deduction, at first glance, I feel that its main role is to prevent theft. In fact, the anti-theft deduction is installed on the inside of the door to prevent us from attacking us when we open the door. In general, the anti-theft deduction will not be used alone, because the type of hardware used in the chain is metal, it is easily cut off, so it is only used as an auxiliary tool.

When you open the door with the anti-theft chain, if you are attacked, you can temporarily prevent the outside person from pulling the door open, and we can use the anti-theft button to close the door in time to avoid injury. Another kind of anti-theft deduction and the above anti-theft chain is not the same, the anti-theft chain can leave a gap to observe the outside, and this kind of anti-theft deduction is another “lock” that is applied after closing the door, which can play a further “locking” role. .

When we want to use the anti-theft deduction to assist, if there is no specific person to help with the installation, when installing indoors, how to install the anti-theft deduction? First, you need to measure the size of the doorway, and then determine the direction of opening based on the corridor outside the door. <In general, the size of the door opening should be larger than the size of the door to be installed, and the distance set on this basis should be set for later adjustment.

Then, the door hole is corrected, and the tool is used for cutting and trimming so that it meets the installation requirements. Finally, the purchased anti-theft fastener is installed in the modified doorway, the handle inside is straightened, and tightened with a screwdriver or the like, and the lock only needs to be locked on the lock cylinder without tightening. Also to remind you that the anti-theft deduction door can not be too thin, to achieve a certain thickness requirements, otherwise it needs to be reinforced with wood.

If you want to replace the door or if you no longer need the anti-theft fastener, you need to remove the installed anti-theft fastener. Then, we will introduce the disassembly method of the anti-theft deduction. First of all, open the safety chain or the buckle tongue, and then use a screwdriver to remove the chain or the tongue portion of the door frame. Then, unscrew the anti-theft fastener behind the door with a screwdriver and remove the two parts.

As the anti-theft fasteners for household hardware products, after removal, traces are generally left on the door frames and doors, including traces of installation and holes. If the holes are large, they can be filled with wood or glass paste. The steps to remove the anti-theft fastener are actually the reverse of the order of installation, so it is difficult to operate.
