This design not only improves the durability and security of the door lock, but also ensures smoother and more stable door opening and closing.
[0003] The lock bodies of the main door locks and bedroom door locks used in every household now all have beveled lock tongues. When closing the door, this beveled lock tongue generates sliding friction between the beveled lock tongue and the lock stop installed on the door frame. The sliding friction of a newly installed lock is relatively small. As time goes by and the beveled lock tongue is used more and more, the friction between the beveled lock tongue and the lock stop on the door frame will become greater and greater, and even have a certain impact on closing the door. When people use too little force, the lock tongue retracts to lock the door, and sometimes no matter how hard you try, you can't lock the door. The noise is also loud, which not only affects people's mood, but also shortens the service life of the lock tongue, increases the cost of replacing or repairing door locks, and is time-consuming and labor-intensive.
