Problems solved by technology

[0004] (2) It is a round lock center with a "snap ball" structure on the side. The structure is complex, and it is extremely inconvenient to assemble the parts. It requires professional labor to be able to assemble, and it is troublesome and time-consuming.
[0005] (3) In addition, because there are complicated beads (or cards), the number of beads and springs assembled in a small space cannot be too many, or even reduced in number, which makes it easier to be stolen. It is the main reason why today's locks are very easy to be stolen.
[0006] (4) The endurance strength of the card bead is not strong, and it is very easy to be stolen by the "destructive method". For example: strong insertion, and then strong twisting can destroy the card bead lock

Abstract

The invention is a multi-ring lock cylinder with higher anti-damage strength and uneasy-to-unlock function, mainly comprising several rings in a cylinder, an inner lock cylinder, and rotating block, where each ring is provided with straight shift groove and fastening pin, these straight shift grooves are mutually corresponding, the first ring is provided with spaced unlocking grooves, and baffle plates are formed between the unlocking grooves and each baffle plate is not equi-wide, therefore the fastening pin of each ring need be accurately pressed back to correspond to each unlocking groove of the first ring so as to be able to rotate the first ring and the rotating block to unlock.

Description

technical field [0001] The invention relates to a multi-ring lock core, which enables the lock core structure to obtain greater damage resistance strength and the effect of being difficult to be stolen. Background technique [0002] Traditional locksets, as everyone knows, are tied in a body with a lock bolt, and a rotatable lock core is set. The lock core is provided with a lock hole of a shape, a ten shape, or a round hole. The side of the lock hole is arranged according to the setting, and the retractable post (bead) or card is inserted into the lock hole by a key with a groove corresponding to the post (bead), so that the card bolt is not locked. The lock core, so that the lock core can be rotated, and then the lock can be moved to unlock; the above structure has the following disadvantages: [0003] (1) There is only a keyhole. Although the space of the keyhole is extremely small, the size of the space is a "fixed aperture". The card column (bead) can be moved and pus...
