The invention discloses a spring lock. The spring lock comprises a casing (1), an internal lock (2) and an external lock (4) mounted in a mounting hole of a door (3), wherein a lock-tongue rod (5) and a pendulum rod (6) for controlling the lock-tongue rod (5) to move along the axis of the pendulum rod (6) are arranged in the casing (1); a lock tongue (7) is arranged at one end of the lock-tongue rod (5), and a stressed board (8) is arranged at the other end of the lock-tongue rod (5). The spring lock is characterized by further comprising return springs (9) sleeving the lock-tongue rod (5), and a limiting board (10) which is arranged on the lock-tongue rod (5) in a sliding matching manner; baffles (11) which are abutted on one side, which is away from the return springs (9), of the limiting board (10) are arranged at the position, which is near the limiting board (10) in the casing (1). The spring lock provided by the invention is convenient for the mounting of the limiting baffles on the basis of ensuring the intensity of the limiting baffles arranged in the casing of the door lock.
