Wheel transmission mechanical lock cylinder and dragon holding cylinder type key

Abstract

The invention discloses a wheel transmission mechanical lock cylinder and a dragon holding cylinder type key, belongs to keys, is suitable for various locks, eradicates the geneogenous defect of the displacement distance of several millimeters of a traditional mechanical lock cylinder, prevents technical unlocking and violent unlocking, and retains the advantages of the traditional mechanical lock cylinder. A dragon like guide rail or guide rail groove on a key body is held on a hollow cylinder; when a key is pushed in, a set of thinner annular transmission wheels in the lock cylinder slides on the guide rail or the guide rail groove, and rotates around the cylinder at the same time, so that the displacement distance is increased to reach several centimeters; after the key is inserted in, a brake wheel is rotated by a push button on a key handle; concave and convex parts on the brake wheel are used for extruding all the wheels, so that all the wheels form a whole; at this time, a transmission rod is fed in a transmission rod groove under the effect of a spring piece; the key is rotated to drive the transmission wheels to push the transmission rod; a poking bolt is rotated to poke a lock tongue to achieve the unlocking purpose; and when the key is pulled out, the wheels are firstly loosened, and then, the key is pulled out.

Description

Technical field [0001] The present invention belongs to the field of locks, specifically, it is a major technical improvement of the existing mechanical lock cylinder, that is, a new technology of the mechanical lock cylinder. Background technique [0002] According to the components that activate the bolt, locks are divided into electronic, photoelectric, magnetic, and mechanical locks (including mechanical code locks and traditional mechanical locks). Because traditional mechanical lock cylinders have congenital defects, new types of locks such as electronic, photoelectric, magnetic, and mechanical combination locks have emerged, but these new locks also have their congenital defects, such as expensive and large space (large volume) ), electronic components are fragile (short life) and rely on electricity. Some electronic and electromagnetic locks are easy to crack, such as magnetic card locks, fingerprint locks, remote control locks, etc. For these reasons, modern new locks ar...

Problems solved by technology

Because the traditional mechanical lock cylinder has congenital defects, new locks such as electronic, photoelectric, magnetic and mechanical combination locks have emerged at the historic moment, but these new locks also have their congenital defects, for example, they are expensive, occupy a large space (large ), electronic components are fragile (short life), rely on electricity, some electronic and electromagnetic locks are easy to crack, such as magnetic card locks, fingerprint locks, remote control locks, etc. For these reasons, modern new locks are difficult to popularize
