Curved lock core and curved key

Abstract

The lock core for curved lock consists of two covers and one middle lock seat. Each of the covers assembled to the middle lock seat has several curved channels communicated through one single curved channel; and the middle lock seat has one single curved channel fitting the single curved channel in the cover, and at least one lock bead unit in the channel. The lock core has one fitted curved key, which is inserted into the curved lock channel for unlocking through pushing the lock bead unit.

Description

technical field [0001] The invention relates to a lock core and a key of a lock, in particular to a lock core and a zigzag key of a multi-channel interrupted zigzag lock with multi-channel entrances, which can reliably prevent thieves from improperly prying and unlocking. Background technique [0002] According to the so-called "zigzag lock", it is the "lock set with a lock core with a zigzag keyhole" (notice number: No. 162749) invented by the inventor and awarded the Taiwan New Patent No. 64720. After the creation and invention of the invention, the inventor continued to improve it according to the actual use situation, and successively applied for and obtained patents such as the announcement No. 239473 "a new structure of directional zigzag key" and No. 240049 "a multi-layer key key structure". The zigzag lock core structure of the directional track". Moreover, in No. 83203732, which was co-created by the present inventor, a structure having an excavation prevention fun...

AI Technical Summary

Problems solved by technology

Among them, the oblique notch structure disclosed in No. 83203732 to achieve the anti-digging function initially has the effect of anti-digging, but because it is only a very shallow oblique notch, the soft material used by those who secretly dig the keyhole It is still possible for the elongated elastic sheet to pass through the beveled notch after being pulled and twisted for a while, so that the beveled notch loses the effect of anti-digging. Then there is the continuous improvement of the new patent application No. 84213580, and the lock core is also improved. Further provide a zigzag lock with better anti-digging effect, and the improvement of the additional (1) patent, which makes it easier to stack and position the sheets of the stacked lock core groove, increases the convenience of manufacturing and assembly, and can further Strengthen the anti-digging effect, because each sheet can also increase the complexity and change of the cross-section of the channel due to the difference in thickness, but in the whole series of research and improvement, please refer to the additional patent No. 84213580A, which is for the zigzag key The zigzag channel 53 for unlocking by advancing the tooth piece, most of the following numbers are excerpted from the original manual, which is curved, or in the additional patent there are multiple elongated holes 531 branching extensions to increase the unlocking ability of thieves. Difficulty, but there is still a chance to be unlocked by the soft strip-shaped elastic sheet 9 in turn. Simply put, as shown in Figure 1, two soft strip-shaped elastic sheets 9 are used, and the first soft strip-shaped elastic sheet 9 is used first. The elastic thin sheet 9 penetrates into the zigzag channel 53, and the end will be stopped by entering the first elongated hole 531 by mistake, but at this time, the second soft elongated elastic thin sheet 9' can be adjacent to the first one. The right side of the right side protrudes into the zigzag channel 53, and when the end is strayed into the second elongated hole 531' and is stopped, the first one is drawn out and then the right side adjacent to the second one is inserted into the zigzag channel. Groove 53, when the end was strayed into the third elongated hole 531 and was stopped, then the second one was drawn out and inserted into the zigzag groove 53 next to the right side of the first one, so that the cross operation was finally completed. There will always be an end that enters the zigzag channel 53 and the rear section 530 has a lock bead (not shown) and pushes it to the lock bead to achieve the purpose of unlocking, so there is room for further improvement
