Description

Technical Field

[0001] The utility model belongs to the technical field of door frames, in particular to a door frame with lock hole protection. Background Art

[0002] The door frame is the structural framework used to install doors in buildings. It supports the door leaf and ensures that the door can open and close stably. During use, the door frame is also connected to the door body through the installed lock to achieve the locking effect, thereby safely partitioning the room. In daily use, most locks are fixed to the door body, and the keyhole is opened on the side of the door frame, or the lock is fixed to the door frame, and the keyhole is opened on the side of the door body. In the installation method where the lock is fixed to the door frame, the lock cylinder may shake due to long-term external forces, and even the keyhole may expand, making the lock less secure. In subsequent use, the locking between the door frame and the door body is insufficient, and the door body may shake due to wind and other factors, producing a loud noise. Especially during rest time, it affects people's normal rest. The expansion of the keyhole will damage the keyhole, which will make the door frame unusable over a long period of time. For users, repairing or replacing the door frame will increase their expenses.
