Padlock

Abstract

The invention discloses a padlock. According to the technical scheme, the padlock is characterized in that a base is provided with clamping grooves; a shell and two clamping rings are included, a hookpart is arranged the other end of the shell, and a limiting piece is arranged between the other ends of the two clamping rings and is provided with clamping protrusions capable of being connected with the clamping grooves in a clamping manner; one clamping ring is sleeved with a torsional spring, and the torsional spring comprises a first torsional spring body and a second torsional spring body;a lock body is further included; when the clamping protrusions of the limiting piece are clamped and connected into the clamping grooves of the base, the hook part of the shell is matched with a buckle part on the other opening and closing face of a bag for limiting, and after the lock body is locked, the limiting piece and the shell cannot rotate, bag locking is achieved, and the first torsionalspring body is in an elastic deformation state; and after the lock body is unlocked, the lock body releases limitation for the limiting piece, the limiting piece rotates so that the clamping protrusions can disengage from the clamping grooves, the second torsional spring body generates elastic deformation, elastic force generated due to elastic deformation of the first torsional spring body drivesthe clamping rings and the shell to rotate, the hook part disengages from a buckle part on the other opening and closing face of the bag, bag unlocking is achieved, and the purposes that during unlocking, operation is simple, and rapid unlocking is convenient are achieved.

Description

technical field [0001] The present invention relates to the technical field of locks, more specifically, it relates to a clasp lock. Background technique [0002] The clasp lock used on the luggage is evolved from the clasp.
