Coded lock structure with improved anti-theft function

Abstract

The invention relates to a coded lock structure with the improved anti-theft function. The coded lock structure comprises a code ring rod, a center rod and a plurality of code rings. The two ends of the code ring rod are respectively provided with a T-shaped connecting rod head, the T-shaped connecting rod heads are inserted into center rod grooves in the outer sides, and the four to six code rings are arranged on the code ring rod in a sleeved mode. Each code ring is provided with nine gears with numbers, wherein one of the nine gears is a hollow gear, and the other eight of the nine gears are respectively and internally provided with a solid steel plate ring. Positioning steel rings are arranged on the left sides and the right sides of the code rings respectively, and a thin steel sheet ring is fixed to the portion, between every two adjacent code rings, of the code ring rod. The coded lock structure has the advantages that a key is not needed, parts are not needed to be replaced, and the stability of a lock is greatly improved; the small steel plate rings can be automatically embedded into grooves; when a code needs to be compiled again, compiling can be easily completed, each code ring has the individual anti-theft function, and the problem that after the code is used for an anti-theft door, the anti-theft door is not safe, not firm, not practical and the like is effectively solved.

Description

technical field [0001] The invention relates to locks, in particular to a combination lock structure with enhanced anti-theft function. Background technique [0002] A combination lock is a type of lock that is opened with a series of numbers or symbols. Some simple combination locks use multiple dials, each dial has a recess in the middle, and a shaft in the center of the lock has several protruding teeth, which are used to block the dial. When the dial turns to the correct code Combination, the lock can be opened. However, many of these locks can be opened without knowing the combination at all. As long as the shaft is pulled outward, one of the teeth will tighten the dial ring more than the other. A small sound means that the tooth has entered the correct concave position. Repeat this step, and the lock can be opened soon. Therefore, the existing codes are usually just permutations rather than real combinations. Some coded locks rotate a group of dial rings engraved wi...

Problems solved by technology

In fact, among the traditional locks, the combination lock is not a product that is frequently used. There are many defects in the existing similar products, for example: ①The lock cylinder part is an inseparable structure. In actual use, you need to put the combination lock All are separated, which has certain potential safety hazards; ②The fixed structure of the code circle is unreasonable and not durable; ③The lock cylinder structure lacks additional anti-theft measures, and there is a problem that the anti-theft door is unreliable, unstable and impractical after using the password; ④ Its structure will inevitably give misbehavior opportunities to unlock; ⑤ Additional keys need to be prepared
