A butterfly lock with lubricating structure

Abstract

The invention belongs to the technical field of butterfly locks, and particularly relates to a butterfly lock with a lubricating structure. The butterfly lock comprises a main lock body and an auxiliary lock body, wherein the main lock body and the auxiliary lock body are fixedly mounted on the upper side edge and the lower side edge of a box body correspondingly; an auxiliary hook piece is arranged on the lower side of the auxiliary lock body, the main lock body comprises a base, a rotatable lock cylinder is hinged to the upper side of the base, and the lock cylinder comprises a lock sleeve and a lock buckle arranged in the lock sleeve in a sliding manner; the left side edge and the right side edge of the lock sleeve are curled to form two blocking sides for limiting the lock buckle, the upper side edge of the lock buckle is provided with a main hook piece in buckled connection with the auxiliary hook piece in a matched manner, the lock buckle is in transmission connection with a rotor, and a butterfly-shaped torsion piece is hinged to the front face of the rotor; and the butterfly lock has the beneficial effects that a pair of reinforcing ribs are designed on the side face of the lock buckle to enable the structure of the lock buckle to be strengthened, in the sliding process, the lock is not prone to deforming, a pair of lubricating rubber strips are designed, the lock buckle is more smooth in the vertical sliding process, and the butterfly-shaped torsion piece is more easily twisted so as to drive the lock buckle to slide.

Description

technical field [0001] The invention belongs to the technical field of butterfly locks, in particular to a butterfly lock with a lubricating structure. Background technique [0002] Butterfly locks are mainly used for bags, flight cases, speaker and light boxes, plastic boxes and rotomolding cases. The lock is firm, easy to use, and has a wide range of applications. High, dropped from the plane to the ground, requiring the flight case not to be opened due to impact, so the requirements for the butterfly lock of the flight case are more stringent, if the lock is not firm after falling, it will cause the flight case to be damaged by the impact Open, so the butterfly locks are all made of stainless steel with better firmness. However, when the butterfly locks made of stainless steel need to be twisted by hand to open the buckle, they are found to be too tight and difficult to twist. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, th...
