The high-strength silent inclined tongue guide sleeve effectively reduces the noise caused by the telescopic movement of the locking tongue. The original patented spring leaf design greatly buffers the closing force of the inclined tongue, and the inner wall of the buckle box is made of high-strength silencing plastic to avoid the collision between the side of the inclined tongue and the metal of the buckle plate and reduce the noise of the switch door in a large range.
How to choose a silent door lock
1, wear resistance. The material of the door lock determines the wear resistance of the lock. The material can be judged by "looking", "weighing" and "listening", such as looking at the shape of a door lock. The appearance of locks made of pure copper is generally polished by sandblasting, so the surface gloss is darker than that of copper plating, but it is natural. When I got it in my hand, I obviously felt that the lock made of pure copper was obviously heavier, while the lock made of stainless steel was lighter. Copper is not easy to be hollow, while stainless steel has strong plasticity and can be hollow. Judging from its sound, when the door lock is opened, the copper door lock is mostly solid, so its sound is not dull, while the stainless steel door lock sounds crisp.
2. Open the feeling. The handle of the door lock is very important, and the required force cannot be too large or too small, which is mainly determined by the spring. The quality of the spring determines the handle and service life of the door lock. If the spring is not good, the handle of the door lock will sag because of the relaxation of the spring, which will affect the service life of the door lock. Therefore, when purchasing, you must personally try the use effect of the door lock spring, and the feel should not be too soft or too hard.
3. Coating of the door lock. The coating of the door lock determines the appearance of the door lock. When buying a door lock, you should first choose the material of the door lock. A good door lock is not easy to peel off the coating. Generally, the coating of a good door lock is not easy to corrode and peel off. A complete and glossy good coating has a great effect on the aesthetics of the whole room.
