Abstract
The utility model relates to a cipher lock of a diesel engine. The inner diameter of a lock seat is provided with a sliding bar, the outer diameter is provided with a lock body, the center of the lock body is provided with an ejector pin, latch steel balls are arranged on the wall, and a lock ring is arranged on the outer diameter. The digital code can code ten thousands groups of ciphers, the confidential performance is good, after latched the cipher lock can not be disassembled, and the anti-theft performance is high. The lock seat can be combined with the diesel engine into an integration, and the utility model has the advantages of simple structure, low cost, high reliability and convenient operation and installation.
Description
The utility model relates to lockset, more particularly is a kind of diesel engine coded lock.
As everyone knows, existing diesel does not all have lockset, and anyone can at will start, and particularly tractor adapted diesel engine easily causes and drives without a license and stolen incident because no lockset can at will start, and makes troubles for driver and social security.
The purpose of this utility model provides a kind of simple in structure, and is with low cost, reliable in function, and installation, easy to use can be combined into whole diesel engine coded lock with diesel engine.
