Anti-theft combination lock for car
First Claim
1. An anti-theft combination lock for car, comprising a main body, a driving unit, a lock rod, a lock plate, and an input interface;
- said main body being provided with a transverse through hole for said lock rod to extend therethrough and thereby associate with said main body;
said main body being mounted on a fixing seat, and a battery compartment and a memory processor being provided on said main body at predetermined positions;
said driving unit being mounted on said fixing seat to locate at one side of said main body with a power output shaft of said driving unit projected from said fixing seat; and
said driving unit being under control of said memory processor;
said lock rod including a rod body provided with a plurality of annular retaining grooves;
said lock plate being a flat body having a rear end provided at a predetermined position with a hole, through which said power output shaft of said driving unit is extended for said lock plate to fixedly connect to said power output shaft; and
said input interface including a keypad and a display located at a top surface of an outer case for said main body, and said keypad being electrically connected to said memory processor, so that signals input via said keypad are sent to said memory processor;
whereby when said lock rod is extended through said through hole on said main body, said lock plate engages with any one of said annular retaining grooves on said lock rod to locate at a locking position and produce a locked state; and
when a user wants to release said lock from said locked state, a password must be entered via said input interface; and
when the entered password is determined by said internal memory processor as correct, said driving unit is actuated to turn said lock plate from said locking position to an unlock position to release said lock rod from said locked state.

Abstract
An anti-theft combination lock for car includes a main body having a transverse hole, a driving unit located at one side of the main body, a lock rod extended through the transverse hole of the main body, a lock plate fixedly connected at an end to a power output shaft of the driving unit to movably locate at an upper outer side of the transverse hole to normally engage with one of many annular retaining grooves on the lock rod to set the lock in a locked state. A password may be entered via an input interface provided on a top of an outer case of the main body. An internal memory processor determines the correctness of the entered password and actuates the driving unit to turn the lock plate to an unlock position when the entered password is correct.
