Embodiment 1
[0022] Example 1: see figure 1 , figure 2 , image 3 , Figure 6 , Figure 8 , Figure 9 , a high-precision ring groove anti-theft lock cylinder, including a lock cylinder shell 1 and a cylinder hole 2 provided thereon, a cylinder 4 with a key hole 3 assembled in the cylinder hole 2, the cylinder hole 2 is The cylindrical shape matches the outer diameter of the lock cylinder 4, and the side wall of the lock cylinder 4 is provided with 7 snap ring seats 6 coaxially arranged therewith. The snap ring 7 matched with it, of course, the number of the snap ring seat 6 and the snap ring 7 here can be set according to the shape and size of the cylinder lock case, at least one, and the number of the snap ring seat 6 and the snap ring 7 is set The more it is, the more difficult it is to realize the technical unlocking, and the better the anti-theft effect is. The clasp 7 is assembled in the cylinder hole 2 and is fixedly connected with the cylinder shell 1. The outer wall of the c...

The invention relates to a high-accuracy ring groove antitheft lock cylinder which comprises a lock cylinder shell, a lock cylinder hole and a lock cylinder body. Clamping ring seats are arranged on the side wall of the lock cylinder body, a clamping ring is arranged in each clamping ring seat, multiple adjusting grooves in inside-outside distribution and an unlocking groove are formed in the side walls of each clamping ring, each unlocking groove and one of the corresponding adjusting grooves are matched to form a ring, sliding grooves communicating inner and outer adjusting grooves and an inner hole of the corresponding clamping ring is formed in the side walls of each clamping ring, lock pin holes are formed in the side wall of the lock cylinder body, the lock pin holes and the clamping ring seats are alternatively distributed along the axial direction of the lock cylinder body, a fixing piece used for limiting the corresponding lock pin is arranged outside each lock pin hole, a first spring is arranged between each lock pin and the corresponding fixing piece in a clamped manner, the inner end portion of each lock pin goes deeply into a key hole while the outer end portion of the same is provided with a convex column, and the head of each convex column can be clamped in the corresponding adjusting groove and the unlocking groove to form rotating fit. During technical unlocking, the adjusting grooves are arranged, so that the high-accuracy ring groove antitheft lock cylinder has high interference effect during position covering and is high in accuracy and good in antitheft effect.
Description
technical field [0001] The invention relates to a lock, in particular to a high-precision ring groove anti-theft lock cylinder. Background technique [0002] The lock core of the traditional mechanical lock is a structure of upper and lower pins, and the beads are managed in layers, so that the thief can first apply a rotational force to the lock cylinder when opening the technology, so that the flat beads are pressed and moved to the side. At this time, the mechanically processed The precision error opens the marbles one by one. When all the marbles are on the same plane, the lock cylinder can be opened, thereby opening the entire lock for theft. Therefore, technology can not be prevented from opening, and the anti-theft effect is poor. Contents of the invention [0003] The invention provides a snap ring with a plurality of adjustment grooves and an unlocking groove that cooperates with one of the adjustment grooves to form a ring, and unlocking is realized by controlli...
