detailed description

The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

As shown in Figures 1 to 5, an embodiment of a butterfly lock with a lubricating structure includes a main lock 1 and a secondary lock (not shown in the figures) fixedly installed on the upper and lower sides of the box respectively, the secondary locks The lower side is provided with an auxiliary hook piece, the main lock 1 includes a base 2, and a rotatable lock core 3 is hinged on the upper side of the base 2, and the lock core 3 includes a lock sleeve 31 hinged to the base 2 and a lock sleeve 31 that is slid up and down on the lock. The lock 32 in the sleeve 31, the left and right sides of the lock sleeve 31 are curled to form the side ribs 310 that limit the lock 32, and the upper side of the lock 32 is provided with the auxiliary hook piece. The buckled main hook piece 320, the lock catch 32 is driven by the rotor 33 that is arranged on the lock sleeve 31 and can slide up and down in the lock sleeve 31. The center of the lock sleeve 31 is provided with a rotor mounting hole 311 of the rotor 33, and the rotor The back of the rotor 33 is adjacent to the lock 32, and a raised eccentric post 330 is fixed on the back of the rotor 33, and the lock 32 is connected to the eccentric post 330 by transmission. Specifically, the lock 32 passes through the transmission through hole 330 'Sleeved on the eccentric column 330, the front of the rotor 33 is hinged with a butterfly-shaped torsion piece 34, and the side of the lock catch 32 away from the rotor 33 is adjacent to the ribs 310 on both sides of the lock sleeve 31. The strip groove 321 provided in the sliding direction, the strip groove 321 is provided with a rubber strip 321' for lubrication, and the other side of the lock 32 opposite to the pair of strip grooves 321 is provided with a pair of Rib 322, through the design of a pair of ribs 322, the structure of the lock 32 is strengthened, and it is not easy to deform during the sliding process; through the design of a pair of rubber strips 321', the lock is smoother during the sliding process, and the butterfly-shaped twist Sheet 34 is easier to twist.
