Abstract

The invention relates to a vertically locking lock cylinder with H-shaped sheets and a cylindrical key thereof. The lock cylinder comprises a casing and a cylindrical cylinder body. A certain number of sheet mounting seams with matched directions are arranged on the cylinder body. H-shaped sheets with matched thickness are arranged in all sheet mounting seams. The middles of the H-shaped sheets are provided with cross beams, the two sides of the H-shaped sheets are provided with vertical legs, the cross beams are arranged on the inner side of the cylinder body and in positions corresponding to the sheet mounting seams, and the cross beams crossly penetrate through the key hole. Notches corresponding to the vertical legs are arranged in the cylindrical casing, a compressed spring is respectively arranged between the upper parts of the cross beams and the inner surface of the cylindrical casing, and a rotating notch is arranged on the outer end surface of the cylinder body. The cylindrical key comprises a key body and a handle, and the key body comprises a cylindrical section and a slope section at the front end of the key body. A certain number of cross notches with matched directions are arranged on the cylindrical section of the key body. A movable chuck capable of axially moving along the key body is arranged at the connection part of the key body and the handle. The vertically locking lock cylinder can prevent technical unlocking and has improved safety.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to an H-shaped sheet for locking up and down a lock cylinder and a cylindrical key thereof. Background technique [0002] In the prior art, there are various locks, such as electronic locks, fingerprint locks, and the most common locks are mechanical locks, which are mainly composed of a lock cylinder, a lock head body and a marble installed in the inner track of the lock head. Composed of a spring, the lock cylinder and the lock body can rotate with each other to achieve the purpose of unlocking, and the combination of the pins and springs and the key together form the key to unlocking. The above-mentioned conventional mechanical tumbler locks are easy to achieve the effect of unlocking through technical methods such as stirring or vibration, resulting in poor security of these locks, which is not conducive to anti-theft. Contents of the invention [0003] The object of the presen...
