Butterfly lock

Abstract

The invention discloses a butterfly lock which comprises a master lock and an auxiliary lock, wherein a spring and a lock core are arranged on the master lock; two grooves I are arranged at both sides of the master lock; a groove II is arranged between the two grooves I; the depth of the groove II is more than the depth of the grooves I; the front surface of the groove II is closed to arrange the lock core; the spring passes through the structure edge of the groove II and is fixed in the groove II; the lock core is fixed on the spring; and a lock latch of the lock core latches the master lock and the auxiliary lock together. Two levels of grooves (grooves I and groove II) are arranged on the master lock of the butterfly lock provided by the invention, thus not only the aesthetic property is increased, but also the safety factor is increased; an accident that the spring scratches people can not occur; and a base structure in the traditional structure is not provided, thereby simplifying the manufacturing process and reducing the product cost.

Description

Technical field [0001] The invention relates to the field of locks, in particular to a butterfly lock. Background technique [0002] Butterfly locks are mainly used for luggage, including aviation boxes, light and sound boxes, blister boxes, rotomolding boxes, etc. The lock is firm, convenient and has a wide range of applications. The butterfly lock in the prior art is composed of 5 parts: main lock 1, auxiliary lock 2, spring 3, lock core 4 and base 5. The base is fixed on the long side by three socket nails, and the spring is fixed to the base through the base. The lock cylinder is fixed on the spring, and the lock cylinder can be used to buckle the secondary lock by rotating the handle to achieve the lock function. [0003] However, the butterfly lock in the prior art has the following disadvantages: [0004] (1) Using the base structure to fix the spring, it is easy to scratch the user's hand during use; [0005] (2) Adopt the base structure to fix the spring, the production eng...

AI Technical Summary

Problems solved by technology

[0004] (1) The base structure is used to fix the spring, which is easy to scratch the user's hand during use;

[0005] (2) The base structure is used to fix the spring, the manufacturing process is complicated and the cost is high;

[0006] (3) Since the spring is fixed by the base, the spring is exposed to the outside, which affects the appearance and the safety factor is not high
