A combined mechanical security lock structure with improved safety performance

Abstract

The invention discloses a combined mechanical security lock structure with improved safety performance, which includes a key and a lock body. The bottom end of the key is provided with a protruding column, and a first turntable is arranged outside the bottom end of the key, and the first turntable Installed inside the installation groove, the top of the lock body is provided with an installation groove inside, and the inside of the installation groove is provided with a vortex spring, and the vortex spring is located on the outer surface of the first turntable, and the bottom of the first turntable is arranged There is a sleeve, and the sleeve is located inside the lock body, and the bottom end of the sleeve is provided with a second turntable, and the second turntable is arranged inside the bottom end of the lock body. The combined mechanical security lock structure that improves safety performance, the shape of the jack on the mechanical security lock structure is a regular hexagon, which is inconsistent with the shape of the jack of most locks on the market, so a specific key is required to unlock the work , effectively improving the safety performance of the mechanical security lock structure.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a combined mechanical security lock structure for improving safety performance. Background technique [0002] The mechanical security lock structure is a lock structure that operates through a mechanical structure. The lock is opened and closed through complex structural features, thereby effectively reducing the operation of unlocking the mechanical security lock structure through other equipment, and The types of mechanical security lock structures on the market are diversified, but the existing mechanical security lock structures still have the following problems; [0003] 1. In the existing mechanical security lock structure, after being assembled and fixed, when the lock is unlocked by a key, the socket on the lock is connected, so that other tools can directly enter the inside of the lock for unlocking operation, which is easy to make the lock The mechanical security loc...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a combined mechanical safety lock structure with improved safety performance, so as to solve the problem that the mechanical safety lock structure on the market proposed by the above-mentioned background technology is directly connected to the internal space of the socket on the lock during operation. , it is easy to insert other unlocking tools into the interior of the lock through the jack for operation, thereby reducing the safety performance of the mechanical security lock structure, and at the same time, the operation of unlocking through the key is too convenient
