Why does the insurance behind the anti-theft door not work? What should I do if the insurance behind the anti-theft door does not work?

We all know that anti-theft doors are a common type of door. Many people install anti-theft doors in their homes, especially the outermost doors. There are many types of anti-theft doors, and different anti-theft doors have different usage effects. Many people find that the anti-theft door insurance does not work when using anti-theft doors. So what is the matter with the anti-theft door insurance not working? Let's take a closer look!

The reasons and solutions for the failure of anti-theft door insurance

Safety is the last line of defense for people inside the anti-theft door lock, so whether it can be used normally is especially important for people inside the room, especially when resting at night. Now let's analyze the reasons and solutions in detail.

1. There is no safety strip installed on the inner panel of the anti-theft door lock, or the safety button on the inner panel of the anti-theft door lock may be rotten and rusted.

Phenomenon: No matter how you turn the safety knob on the inner panel, the safety tongue on the lock body cannot be activated normally.

Solution: ① Remove the two screws on the inner panel. ② Install the safety button on the panel. If you don’t have the accessories at home, you need to buy a panel on the market. ③ Install the panel handle with the safety strip on the anti-theft door lock, and the problem will be solved.

2. The flat strip or square strip of the safety button on the inner panel of the anti-theft door lock is not inserted into the safety hole of the lock body.

Phenomenon: Occasionally, there will be a jamming feeling when twisting the inner panel safety knob. This is because the safety flat bar is not inserted into the safety hole of the lock body, and the flat square bar rotates inside the panel, causing the jamming feeling.

Solution: ①Remove the two screws on the inner panel. ②Insert the flat strip of the safety button on the inner panel into the safety hole of the lock body. ③Fix the two panels with screws to solve the problem.

3. The safety hole of the lock body is damaged. Generally, the safety hole is rusted and rotten, and the spring at the safety hole is rusted and broken.

Phenomenon: When rotating the panel safety button, there is occasionally a sense of jamming, but the safety tongue cannot be used normally.

Solution: In this case, the general option is to replace the lock body. Most other methods are only temporary solutions and do not address the root cause.

4. The safety lock tongue on the lock body is bent, which is generally caused by human error.

Phenomenon: The safety tongue on the lock body cannot extend or return to its original position.

Solution: ① Ask a professional to disassemble the lock body and straighten the safety tongue, but the effect will be slightly worse than a new lock body. ② Replace the lock body.

5. The safety tongue, safety button and flat strip are intact. The door frame and door leaf are misaligned due to quality problems of the anti-theft door.

Phenomenon: When the door is open, the safety tongue can be opened normally. Once the door is closed, the safety tongue can be opened with a metal feel.

Solution: Use a file to enlarge the lock hole of the safety tongue on the door frame downwards, and the problem will be solved naturally.

Summary: The first two questions are about handles and installation; questions three and four are about the quality of the lock body; question five is about the quality of the security door; so grade A security doors should be selected as the main ones, and the locks must be inspected and accepted after installation.

Precautions for installing anti-theft door locks

1. When installing the lock body, if there is a top and bottom lock, be sure to hang the top and bottom lock on the top and bottom hooks of the lock body, otherwise the top and bottom hooks may fall into the top and bottom holes and fail to open the anti-theft door during later use.

2. When installing the handle, make sure that the safety strip is long enough to be inserted into the safety hole of the lock body. If it is too short or only inserted a little, the safety tongue may not be able to extend or retract normally during later use.

3. The length of the square bar must not be too short. If it is too short, the square bar will run into the handle hole. If there is no insurance in the room, the handle cannot open the anti-theft door.

4. The two screws of the lock core cover should not be tightened too much, otherwise it will cause resistance to rotation when the key opens the door.

5. Before installation, check whether the panel is straight. If it is not straight, it will cause resistance to key rotation.

How to buy anti-theft door locks and handles

⒈Buy lock body

①First of all, the heavier the lock body, the better. After explaining the material of the lock body, it is not easy to rot and rust, and has a long service life.

②The material of the lock body can be stainless steel. Stainless steel lock bodies are currently the most expensive and best quality on the market.

③Be sure to try it out in a store before buying it. Check whether the lock opens and closes smoothly and whether the safety can be extended and retracted freely.

④The material of the lock body safety hole must be solid steel or iron. This type of material has a relatively long life and is not easy to rust or rot.

⒉Buy handles

① Stainless steel and zinc alloy can be considered. These two materials have long service life and high strength. Of course, their prices are also the highest among the two types of anti-theft door locks (except copper).

② Anti-theft door handles can be considered to have lining reinforcement. Here the handle has high strength and good anti-destruction performance.

③ The gap at the fuse button position should not be too large, and the material should be iron, zinc alloy, stainless steel, etc. If the gap is large, the switch fuse feels bad, and it feels like it is about to fall apart. As for the material, the main consideration is its service life.
