Abstract

A combined double plug theftproof dead bolt cylinder is composed of a lock body, a front lock cylinder, a rear lock cylinder and a key and is characterized in that: the key is composed of a front key and a rear key; an inserting bar is arranged at the two sides of the front end of the front key and key teeth are arranged on the inserting bar, while a pivot is arranged between the two inserting bars and the rear key is provided with a shaft hole and is pivoted with the pivot; the rear lock cylinder is provided with an inner cavity for mounting the front lock cylinder, while the front lock cylinder is arranged in the inner cavity of the rear lock cylinder and two jacks are arranged on the rear lock cylinder; after the front key rotates, the inserting bar is matched with the jack and the key teeth on the inserting bar are matched with the top ball in the jack. Because such structure is applied, the structure is simplified relative to the existing technology; only after the front key and front lock cylinder rotate by a certain angle, the front key is inserted into the inserting bar so as to be inserted into the jack of the rear lock cylinder and then to be matched with the top ball, and the key is turned again to rotate the rear lock cylinder, so the utility model has a simple structure and a low cost but also has a high theft prevention capability.
