Abstract
The utility model discloses a shock absorption door lock. The shock absorption door lock comprises a main spring bolt and a shock absorption device. The shock absorption device comprises a rotating component, a limiting device and a bias pressure component, wherein the rotating component is connected to the main spring bolt in a rotating mode through a hinge pin; an extending end abutting against a front panel of a lock shell is formed on the rotating component; the limiting device is used for limiting rotation of the extending end; the bias pressure component has bias pressure enabling the extending end to tend to rotate towards the limiting device. The main spring bolt drives the rotating component to move towards the front panel of the lock shell, the extending end abuts against the front panel of the lock shell, then bias pressure of the bias pressure component is overcome, and the extending end moves in the direction away from the limiting device. According to the shock absorption door lock, in the locking process of the main spring bolt, the extending end of the rotating component is driven by the main spring bolt to abut against the front panel of the lock shell, as the bias pressure on the rotating component from the bias pressure component needs to be overcome, the locking speed of the main spring bolt is decreased, a spring bolt installing board can be prevented from striking the front panel of the lock shell, and the main spring bolt can also be prevented from striking a door frame; the shock absorption device is located in the lock shell and will not protrude out.
