Lock assembled with bidirectional locking spring in elliptical rotary arrangement

Abstract

The invention relates to a lock assembled with a bidirectional locking spring in elliptical rotary arrangement. The lock comprises a lock core encloser, a lock core external body, a lock core internal body component, a locking spring component and a key. The lock core internal body component comprises a lock core, a pedestal and a positioned central pole. The locking spring component comprises at least three first-direction locking spring components and second-direction locking spring units in elliptical rotary arrangement. The first-direction locking spring component consists of at least two first-direction locking spring units in parallel arrangement. Each first-direction locking spring unit consists of an upper section locking spring, a lower section spring and a spring in assembly. The second-direction locking spring unit consists of the upper section locking spring, the lower section spring and the spring in assembly. A key body is an elliptical main body bar structure and is provided with a guidance convex body bar and at least three semicircular grooves at the surrounding wall. The center of the key is provided with a central pole guidance hole. Each semicircular groove is provided with a locking spring hole. The positioned central pole penetrates through the lock core and the pedestal and is butted with a central through hole of the lock core encloser. The positioned central pole is introduced into the central guidance hole of the key.

Description

technical field [0001] The invention relates to the field of anti-theft locks composed of tumbler lock heads, in particular to a lock equipped with bidirectional tumblers arranged in an elliptical rotary arrangement. Background technique [0002] As an important daily necessities that are widely known and widely used by users, locks have higher and higher requirements for their safety and anti-theft performance. At present, there are many types of anti-theft locks at home and abroad. For all kinds of anti-theft locks on the market, the in-line, cross-type, S-shaped, and axial cylindrical keys are usually used to open and close the principle of the corresponding lock cylinder. The original structure of the lock cylinder , the processing technology requirements are not high, because the structure of the internal lock core of the anti-theft lock can be seen or judged from the appearance, so it is easier to configure another key in the anti-theft lock, and normal users do not ne...

AI Technical Summary

Problems solved by technology

Because this invention adopts two lock cylinders, two groups of marbles arranged on the two lock cylinders can play a better anti-theft effect than a lock cylinder, but in the anti-theft structure, it is still unsatisfactory; It is still relatively easy to configure another key, and the technology of the lock with the rotary structure has not yet been disclosed
