Abstract
The utility model relates to an unlocking mechanism for bar-shaped cipher locks, which comprises a cipher wheel, a lock bolt and an unlocking knob, wherein the inner of the unlocking knob is fixed with an unlocking dialling wheel, and a circular arc-shaped propelling slope is arranged on the unlocking dialling wheel. One end of the lock bolt mutually sheathed with the cipher wheel is movably penetrated through the unlocking dialling wheel and is positioned in the unlocking knob, and the lateral face of a circular disc on the end part of the lock bolt is matched with the circular arc-shaped propelling slope; a self-locking spring is arranged between the other side of the circular disc and the back wall of the unlocking knob. A restoring torsional spring is arranged between the unlocking dialling wheel and the circular disc, and the inner of the unlocking knob is provided with a limiting groove which is matched with a spacer pin in a lock body. The utility model overcomes the defect of complicated unlocking process of an ordinary unlocking mechanism for bar-shaped locks in the prior art, and the utility model can complete unlocking operation in a simple rotating mode through the design. The utility model has the advantages of convenient operation, novel and compact structure, convenient and flexible operation and strong reliability.
Description
Affiliated technical field
The utility model relates to a kind of password stripe shape lock unlocking mechanism.
Background technology
The mode of unblanking of tradition stripe shape lock generally adopts plug-in, extracts the real torr of connection-peg again by key rotation lock core and sees and unblank.Comparatively speaking, its process of unblanking is more loaded down with trivial details.
Summary of the invention
In order to overcome the more loaded down with trivial details problem of the process of unblanking of common stripe shape lock unlocking mechanism in the prior art, the utility model provides a kind of stripe shape lock unlocking mechanism, novel structure compactness, convenient and flexible operation, the good reliability of this stripe shape lock unlocking mechanism.
The technical scheme that its technical problem that solves the utility model adopts is: comprise cipher wheel, dead bolt and Unlocking knob, the wheel of in Unlocking knob, fixedly unblanking to pull out, unblank to pull out wheel and be provided with circular-arc propelling inclined-plane, one end activity of the dead bolt that socket-connects with cipher wheel is passed and is unblanked to pull out wheel and be positioned in the Unlocking knob, match with circular-arc propelling inclined-plane in disk one side of its end, between the rear wall of opposite side and Unlocking knob self-locking spring is set, unblank to pull out the wheel and disk between reduction torsion spring is set.
Being provided with stopper slot in Unlocking knob matches with spacer pin in the lock body.
The utility model can be finished unlock operation by above-mentioned specific design with simple rotation mode, uses very easyly, has the advantage of novel structure compactness, convenient and flexible operation, good reliability.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is a stopper slot project organization schematic diagram.
As shown in the figure, the utility model comprises cipher wheel 10, dead bolt 1 and Unlocking knob 2, in Unlocking knob 2, fixedly unblank to pull out wheel 3, unblank to pull out wheel 3 and be provided with circular-arc propelling inclined-plane 4, one end activity of the dead bolt 1 that socket-connects with cipher wheel 10 is passed and is unblanked to pull out wheel 3 and be positioned in the Unlocking knob 2, match with circular-arc propelling inclined-plane 4 in disk 5 one sides of its end, self-locking spring 6 is set between the rear wall of opposite side and Unlocking knob 2, unblank to pull out the wheel 3 and disk 5 between reduction torsion spring 7 is set, in Unlocking knob 2, be provided with stopper slot 8 and match with spacer pin 9 in the lock body.When unblanking, rotate counterclockwise Unlocking knob 2, the circular-arc propelling inclined-plane of unblanking to pull out on the wheel 34 that rotates simultaneously moves right by disk 5 sides promotion dead bolt 1, self-locking spring 6 and reduction torsion spring 7 are compressed simultaneously, dead bolt 1 separates with connection-peg 11 unblanks, unclamp Unlocking knob 2 after, self-locking spring 6 and reduction torsion spring 7 reset simultaneously, dead bolt 1 moves right, and locking closes.
