Talk about door locks

What’s the solution? Is the toilet lock particularly fragile? Is it really bad to judge at this point?

Many families feel that their door locks are broken every day, and toilet locks are even more subject to frequent replacement. What's the reason behind it? When you twist the handle but can't open the door, does it mean the lock is broken? Today I will share with you the details of dismantling the door lock.

Why does the door lock "feel like it's often broken"?

Large quantity・Enlarged probability

A house usually has many doors: master room, guest room, children's room, study room, toilet door, etc. Assume that the failure rate of each lock is 1%, but when you have 5 door locks, the chance of a house experiencing lock failure becomes about 5%."The large number" makes you feel that the lock is broken all the time, in fact, it is not the same lock that breaks every day, but the problem of different lock wheels leaking out.

Psychological factors・Impression bias

Every time there is a problem with the door lock, it will directly affect your life (for example, you cannot open the door when you return to your room at night). It is easy to remember. Compared with the door lock that may break once every few years, if several door locks break in turn, you will feel that they are "broken all the time." In fact, the overall failure rate may not be higher than that of door locks;The frequency of being locked impresses you。

Why is the toilet lock so fragile?

Used extremely frequently

The toilet is the space that the whole family uses most frequently every day. Each person may open and close the toilet door 5-10 times a day, and a house of 4 people may open and close the toilet door more than 20-40 times a day. With tens of thousands of operations accumulated in a year, the lock cylinder wears out and the spring fatigues much faster than other door locks.High frequency use = faster aging。

Moist environment erosion

The toilet is wet for a long time, and the water vapor will penetrate into the inside of the lock body, causing the metal parts to rust and the lubricating oil to emulsify. Especially for round toilet locks, the internal springs and tenons are easily stuck due to rust. Once rusted, it will feel "tight" when twisted and may eventually break.Moisture + frequent use = double whammy。

How to tell if the door lock is broken? Diagnosis of "Twist but can't open"

The most common situation: the handle or knob can be rotated, but the door lock does not pop up, does not respond, or gets stuck when turned to a certain angle. The following steps will help you determine if the system lock is broken or if there are other problems.

Quick judgment processListen to the sound to identify the location: Is there a "click" sound when twisting? Normally, the oblique tongue or square tongue on the inside of the lock cylinder should have a crisp bouncing sound. No sound may be caused by the internal slingshot being broken or parts falling off.
Feel the resistance: Normal twisting should have uniform resistance. If it is loose when twisting (without any resistance), the lock cylinder may have separated from the transmission rod; if it is tight or even tight, it may be rusted or stuck by foreign matter.
Check the slope: Looking in from the side of the door (locking plate position), see if the latch tongue is sticking out? If the handle twists but the latch does not retract, it means the internal transmission has failed.
Test backup key: If the door lock itself has a keyhole, try inserting and turning the backup key. If the key cannot be opened, it is confirmed that the lock cylinder is damaged.
Exclude door frame deformation: Sometimes it is not the lock that is broken, but the door frame sinking or the weather deforms the door panel, causing the keyhole to be misaligned. You can try gently lifting or pushing the door while twisting the handle. If it opens, it's a problem with the door frame, not the lock.

Conclusion: If the above tests show that the lock cylinder does not drive the latch bolt normally, it means that the internal parts of the lock have been damaged and the lock body needs to be replaced or repaired by a locksmith.

Common fault types of room door locks

Internal slingshot broken

Frequent use causes the metal of the spring to fatigue. After breaking, the latch tongue cannot automatically pop up or retract. Symptoms: After twisting the handle, the tongue has no reaction.

Toilet locks are the most common. Symptoms: It is very laborious to twist, and you even have to use pliers to twist it hard first, and finally the connecting rod breaks.
