Abstract
The utility model provides a handwheel mechanism for opening safe and vault doors, comprising a handwheel, a handwheel shaft, an internal-tooth driving wheel, an external-gear driving wheel, a return spring, a latch shifting rack and a 3-lock control terminal bolt. When the door of the safe or vault is locked, the external-tooth drive wheel does not engage with the internal-tooth drive wheel; therefore, the drive handwheel can only cause idle running thereof, but other parts can not be driven. The handwheel mechanism for opening safe and vault doors can eminently enhance the difficulty of destruction to the safe or vault by a large-torque wrench.
Description
Technical field
The utility model relates to the design of medium-and-large-sized safety cabinet and national treasury, the mechanism of the handwheel that is specifically related to open the door.
Background technology
At existing safety cabinet and national treasury that financial industry is used, its handwheel that opens the door is stuck when door lock is lived state and can not rotates.This structure, if under the effect of high pulling torque wrench, internal mechanism is very easily destroyed, thereby becomes a big potential safety hazard.
The utility model content
The purpose of this utility model provide a kind of in, the handwheel that opens the door of large-scale safety cabinet and national treasury, make door when locking-in state, the handwheel that opens the door is in the skid state under external force, thereby avoids damaging inner relevant transmission mechanism, improves safety protection function.
The technical solution of the utility model is:
The handwheel that opens the door of a kind of safety cabinet and national treasury, comprise handwheel 1, hand wheel shaft 2, other driving member, it is characterized in that: described other driving member comprises internal tooth drive 3, external tooth drive 4, back-moving spring 5, keeper mobile rack 7, three lock joint control terminal dead bolts 6; Described handwheel 1, internal tooth drive 3 and external tooth drive 4 are installed on the same hand wheel shaft 2, internal tooth drive 3 and handwheel 1 are fixedly connected on the two ends of hand wheel shaft 2 respectively, external tooth drive 4 skies are enclosed within on the hand wheel shaft 2, and back-moving spring 5 is between internal tooth drive 3 and external tooth drive 4; Under the resilient force of back-moving spring 5, external tooth drive 4 remains with fixed support 11 towards the end face of handwheel and contacts; The cylindrical of internal tooth drive 3 is provided with all grooves, and the thickness of the width of described groove and three lock joint control terminal dead bolts 6 is suitable; Keeper mobile rack 7 is meshed with external tooth drive 4; When safety cabinet or national treasury door were in locking-in state, three lock joint control terminal dead bolts 6 inserted in the groove of internal tooth drive 3 cylindricals, and both are in disengaging configuration external tooth drive 4 and internal tooth drive 3; When lock is opened, promptly three lock joint control terminal dead bolts 6 shift out in the groove of internal tooth drive 3 cylindricals, and after being pulled outwardly out handwheel 1, and both are meshed external tooth drive 4 and internal tooth drive 3.
From said structure as can be seen, when safety cabinet or national treasury door are in locking-in state, because the external tooth drive is not meshed with the internal tooth drive, so rotates handwheel it is dallied, and can not drive other parts.
The handwheel that opens the door of safety cabinet that the utility model provides and national treasury can significantly strengthen and use the difficulty of high pulling torque wrench to safety cabinet and national treasury destruction, thereby improve safety protection function.
Description of drawings
Fig. 1 is the utility model structure principle chart;
Fig. 2 is the sectional view along hand wheel shaft center line among Fig. 1.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model comprises terminal dead bolt 6, keeper mobile rack 7, the keeper 8 of handwheel 1, hand wheel shaft 2, internal tooth drive 3, external tooth drive 4, back-moving spring 5, three lock joint controls, the stop tab 9 and the block bolster 10 of keeper mobile rack; Wherein handwheel 1, external tooth drive 4, back-moving spring 5 and internal tooth drive 3 are installed on the same hand wheel shaft 2, internal tooth drive 3 and handwheel 1 lay respectively at two ends of hand wheel shaft 2, internal tooth drive 3 is all fixedlyed connected with hand wheel shaft 2 with handwheel 1, mutually can not relative motion; External tooth drive 4 skies are enclosed within on the hand wheel shaft 2, so hand wheel shaft 2 can relatively rotate and move axially with external tooth drive 4; Back-moving spring 5 is between external tooth drive 4 and internal tooth drive 3, under the resilient force of back-moving spring 5, external tooth drive 4 is all the time near fixed support 11, if no external force forces handwheel 1 outwards to be pulled out, then external tooth drive 4 and internal tooth drive 3 are not meshed; The cylindrical of internal tooth drive 3 is provided with all grooves, and the width of this groove is slightly larger than the thickness of the terminal dead bolt 6 of three lock joint controls; Keeper mobile rack 7 is meshed with external tooth drive 4; When safety cabinet or national treasury door are in locking-in state, both break away from external tooth drive 4 and internal tooth drive 3 mutually, the terminal dead bolts 6 of three lock joint controls are inserted in the groove on internal tooth drive 3 cylindricals, hand wheel shaft 2 axial moving have been limited, promptly handwheel 1 can not be outwards extracted this moment, and handwheel 1 can only be rotated; When lock is opened, the terminal dead bolt 6 that is about to three lock joint controls shifts out in the groove of internal tooth drive 3, the stop tab 9 of keeper mobile rack withdraws from the stop breach on the keeper mobile rack 7 simultaneously, outwards extract handwheel 1 this moment, back-moving spring 5 by compression, internal tooth drive 3 is meshed with external tooth drive 4, rotates handwheel 1 then and can drive keeper mobile rack 7 and move, thereby keeper 8 is opened.
