Description

Technical Field

[0001] The utility model belongs to the field of locks, and in particular relates to a spring buckle lock. Background Art

[0002] Push-type spring snap locks are mainly used in doors, windows, cabinets, drawers and other fields. Its structure includes: a lock shell and a lock core that can be slidably arranged in the lock shell, a lock core groove is provided on the side of the lock core, a U-shaped lock pin that matches the lock core groove is provided at the bottom of the lock shell, a reset spring is provided between the bottom of the lock core and the lock shell, and a clamping buckle is provided on the top of the lock core. The self-locking function of the snap lock is achieved by the U-shaped lock pin and the lock core groove. Existing disadvantages: Due to structural limitations, the reset spring is usually provided on one side of the bottom of the lock core, which makes the lock core easy to tilt to one side after assembly, which easily leads to the clamping buckle not being able to accurately dock with the snaps on doors, windows, cabinets or drawers.
