A combination of double rotary lock and open key

Abstract

The invention relates to a combination of a dual-rotation lock and an opening key. A metal block body with a circular through hole in the middle serves as a lock body. A rotating ring and a rotor are concentrically placed in the circular through hole. A locking lock cylinder is located in the metal block body and is close to the circular through hole. The rotating ring and the rotor can relatively rotate. The rotating ring and the locking lock cylinder can relatively rotate. By means of the combination, when the opening key is not inserted, the rotor can rotate relative to the rotating ring, and the rotating ring can be locked relative to the lock body; it is prevented that the lock is rotated and opened through forced-opening tools; and the combination has good anti-theft performance and is suitable for different rotating locking drive bolts.

Description

technical field [0001] The present invention relates to a lock and a key suitable for the lock, namely a combination of a double rotary lock and an open key. Background technique [0002] At present, the popular side post marble locks on the market, also known as "atomic" locks, use external force to push or rotate the lock cylinder containing the key socket to directly or indirectly unlock the lock. The key socket of this anti-theft lock cylinder There are many shapes such as: "once", "cross", "semi-arc", "plum blossom", "cylindrical" and so on. The whole body of the anti-theft lock is made of steel. On the surface, the anti-theft lock has very good anti-theft performance, and the market is also very popular. However, in real life, practical cases of theft of this lock often occur, and the lock cylinder is destroyed by a lawless person with a force-opening tool or a miniature electric drill, and the lock cylinder can be opened technically in a few seconds. Because this an...

Problems solved by technology

Therefore, it provides a large unlocking space for professional technology or violent unlockers, resulting in poor anti-theft performance.

[0003] In order to solve the above problems, the applicant disclosed a hidden rotary lock cylinder in Chinese Invention Patent Application Publication No. CN103883168A on June 25, 2014, including a lock cylinder and a rotary locking drive bolt; A square or cylindrical block with a round through hole; two strip-shaped channels with different widths are arranged in parallel inside the lock cylinder; among them, the wide strip-shaped channel communicates with the front of the square or cylindrical block to form an insertion port; the narrow strip-shaped channel is connected to the front of the square or cylindrical block. The front end of the square or cylindrical block is blocked; a partition wall is formed in the lock core between the wide strip-shaped channel and the narrow strip-shaped channel; there is a pinhole section in the narrow strip-shaped channel, and there is a pinhole in each pinhole. The side column marble; the present invention also relates to an open key in the shape of an inverted "U" and the above-mentioned hidden rotary lock cylinder. The technology of thieves is prevented from unlocking, but there is still the danger of turning the handle to drive the locking drive bolt to unlock when using a forced opening tool
