Description

Cipher disc without locking slot on outer circumference

Technical Field

The invention belongs to the technical field of code discs of mechanical digital locks, and relates to a code disc with an outer circumference provided with no locking slot.

Background

The defect of the design scheme is obvious because the locking grooves of most mechanical digital discs in the prior art are arranged on the outer circumference of the digital discs, and larger gaps exist between different levels of coded discs due to the limitation of a processing technology, so that probes can be directly inserted into accurate judging and positioning unlocking positions by using the gaps, technical unlocking is implemented, and the safety performance of the coded disc is greatly reduced; secondly, the inner disc (namely the inner disc of the coded disc in the patent) is fixedly arranged in the center hole of the outer disc by adopting an O-shaped spring, and the O-shaped spring is an elastic element, so that the elastic performance of the O-shaped spring is reduced in the long-term use process, and the fastening capability of the O-shaped spring to the inner disc is reduced, so that the O-shaped spring can rotate along with the rotation of the inner disc in the decoding process, the performance of the coded locating pin serving as the coded disc can be seriously influenced, and even the function of the O-shaped spring can be lost (the position where the O-shaped spring notch deviates from the locating pin can block the locating pin from being meshed with the locating tooth on the inner disc so as to influence the locating function); finally, the diameter difference generated by rotation of the sliding shifting heads in the code adjustment process can be overlapped, the error of the traditional digital lock can be multiple times of the standard error when the traditional digital lock reaches the last stage, the accuracy of code adjustment is affected, the phenomenon that the strength and the positioning accuracy are too low due to the design structure of the driven sliding shifting heads is common, and the phenomenon that the sliding shifting heads are damaged due to too large force of an unlocking person is easy to occur.

Disclosure of Invention

Based on the technical problems in the background art, the invention provides the coded disc which is simple and reasonable in structure, small in poking error and high in poking device strength, and the outer circumference of the coded disc is not provided with the locking slot.

Further preferably, a locator is arranged in the locator groove through the connection of the pin shaft and the locator locating spring, wherein one end of the locator is provided with a locating clamping head, the other end of the locator is of a U-shaped structure, the tail end of the U-shaped structure is provided with a connection fixing hole, and the locator on one side opposite to the locating clamping head is provided with a locator locating spring groove.

Further preferably, the positioning chuck points to the circle center direction of the disc body under the action of the positioning spring of the positioner.

Further preferably, the radius of the circumference of the outer side of the fixed shifting head on the inner disc is smaller than the radius of the inner disc positioning shoulder in the circle center hole of the outer disc, and the length of the fixed shifting head away from the disc surface of the inner disc is 2 times the thickness of the inner disc positioning shoulder.

Further preferably, a through code adjusting rod jack is arranged on the outer disc positioned at the inner side of the locator groove.

Compared with the prior art, the device provided by the invention has the following advantages:

1. the outer circumference of the outer disc of the password is not provided with the locking clamping groove, but the end face hidden type locking clamping head blind groove is matched with the locking clamping blind groove, so that the unlocking position is hidden, and the defect that the probe is used for easily finding the unlocking position when the password is stolen is effectively avoided;

2. the fixing mode of the inner disc (namely the core disc for coding pointed by the practitioners in the same row) of the coded lock adopts the annular groove-shaped inner disc chamber formed by the outer disc shoulder, and has obvious advantages compared with the traditional fixing mode of adopting an O-shaped spring, for example, the traditional O-shaped spring fixing mode has the elasticity weakening along with the use time, the O-shaped spring can displace along with the rotation of the inner disc, and the coding locating port state can be blocked;

3. adopt the slidingtype shifting block, can be because of the wobbling angle stagger of slidingtype shifting block is because of the diameter difference of fixed shifting block nail, the superimposed size error of shifting block diameter when each fixed shifting block nail mutually dials has further been improved the precision of trick lock, the slidingtype shifting block of arc structure has increased intensity effectively, prevent to cause the damage to the trick lock inner disc because of the operator is too big with the power in the use, lead to even the direct fracture of slidingtype shifting block, cause the damage of trick lock, also prolonged the life of trick lock effectively.
