Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] A mechanical password device, comprising a housing, a shaft 8, an outer password wheel 5, a password setting switch, an anti-retraction baffle 6, a withdrawal switch, and a reset switch 11. It is characterized in that: the device also includes an inner password wheel 7. The shaft 8 described above has a linear groove 12 along the axial direction, and has an annular groove 10 on the shaft body; the outer surface of the outer code wheel 5 is processed with a code mark, and the outer code wheel 5 is provided with a truncated circular groove along the axial direction. Through hole, the truncated through hole is coaxial with the outer cipher wheel 5, and gear teeth are processed along the direction of the generatrix in the truncated through hole; the inner cipher wheel 7 is in the shape of a sleeve, and the outer surface of the end of one end is processed into a trunc...

Abstract

A double-sided adjustable mechanical password device belongs to the field of machinery, including a housing, a shaft, an outer password wheel, an inner password wheel, a password setting switch, an anti-retraction baffle, a withdrawal switch, and a reset switch. Groove and annular groove; the outer password wheel is processed with a password mark, and the outer password wheel and the inner password wheel are meshed through helical gears; the inner password wheel is in the shape of a sleeve, and the inner wall of the sleeve is provided with bumps; The shaft ring groove and the linear groove slide to complete the exchange of the unlocked and locked states of the password device; a new password can be set by exiting the meshing state of the inner and outer password wheels. The invention has a simple structure, can realize operations such as changing passwords on both sides, is simple to operate, can eliminate the possibility of technical opening, and has high security.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a mechanical encryption device. Background technique [0002] With the development of society and the progress of technology, there are more various technologies related to locks or cryptographic devices with switch functions. Among them, most of the locks that are directly opened by the key are locked and opened by the combination of the lock cylinder pin and the shaft. Because the volume of the lock cylinder pin of the lock is limited by the volume of the lock hole, most of them are the size of rice grains, which can be strongly damaged. Small and large lock cylinder pins are easy, so the security of this type of lock is poor. At present, the password of the password device equipped on most domestic safes can only be set by the manufacturer of the safe during the production process, and the password cannot be changed. And there are various links such as production, transp...
