Lock assembled with equilateral bidirectional locking spring

Abstract

The invention relates to a lock assembled with an equilateral bidirectional locking spring. 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 an upper lock core, a lower 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 equilateral arrangement. The first-direction locking spring component consists of at least three 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 also consists of the upper section locking spring, the lower section spring and the spring in assembly. A key body is provided with a guidance convex body bar and semicircular grooves which are distributed in equilateral array. The center of the key is provided with a central pole guidance hole. Each semicircular groove is provided with a locking spring hole. The lower end of the positioned central pole penetrates through the lower lock core and the pedestal sequentially and is butted with a central through hole of the lock core encloser. The positioned central pole is adaptive to be 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 equilateral two-way pins. 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 need to prepare the key of the lock with a pr...

AI Technical Summary

Problems solved by technology

Because this patent adopts two lock cylinders, two groups of pins 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; on this anti-theft lockset, if It is still relatively easy to configure another key, and the technology of the lock with the rotary structure has not yet been disclosed
