The task of the anti-theft door is to prevent it from breaking. It is the locking cylinder that really controls the telescopic opening of the locking point. As long as the locking cylinder is open, all locking points can also be opened.
What types of door locking cylinders are there?
What are the precautions for the use of locking cylinders?
What are the purchase criteria for door locking cylinders?
Cylinder type – latch cylinder
Another type of cylinder that most of us use every morning when we walk out the door is a latch cylinder. From the outside of the door, the key must turn the cylinder to retract the latch. Depending on the option ordered, the inside of the bar can be rotated with a thumb or a key.
Cylinder type – Profile cylinder
Cylindrical profile locks are common in Europe, but are not widely used in the US, with the exception of storm doors. They have an oval or drop-shaped shape with a cam in the middle that serves both sides of the lock.
Always check the appropriate gap between the lock body and the lock plate, whether the height of the lock tongue and the opening of the lock plate is appropriate, and the appropriate gap between the door frame and the door preferably is 1.5mm to 2.5mm mm.
The locking cylinder must not be exposed to rain or rinsing water because the spring is too small, rusts and fails and cannot be stretched.
If the machine key is shaken too hard, it will wear off, and if the locking cylinder is too long, the key will slip off.
The first trick: before buying a lock, you can assess the quality of the locking cylinder on the basis of the cost of key teeth. It mainly depends on the structure of the locking cylinder.The leaf-side column structure is often much better than the traditional marble structure. Professional teachers seek advice and then choose according to the situation.
The second trick: crack a lock and weigh it by weight and look at the locking cylinder individually by weight. The heavier the weight, the better the quality of the locking cylinder, the more beads in the locking cylinder, the better the anti-theft protection.
The third measure: select the locking cylinder to see the color, and compare the color with the workmanship. The locking cylinder of good quality is galvanized, the surface is smooth and the color is bright. Among them is the dark yellow color of the copper core, which is relatively strong and has good anti-theft performance.
