Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.

Gear 3 is the stairstepping of band through hole, and large end has tooth, and small end is anodontia.

Handle is slidably matched by handle cover 2-1 and handle set 2-2 and forms, have the axle 2-12 of a band annular groove 2-11 in the middle of handle cover inwall, outer shaft sleeve connects spring 25, and relative both sides, axle lower end are pancake, axle 2-12 and gear 3 connect into entirety, and axle can forward and backward movement in the middle of gear.

Card 20 is strip, and there is bending 20-1 one end, and the other end has waist hole and through hole on the surface respectively, fixes a screw 20-2 spacing in pressing plate 4 and waist hole.

The soffit of handle set 2-2 has the boss of band opening, there is blind hole boss lower end, little spring 28 is installed in blind hole, the two side at boss openings place there is chute, card is moved around in chute and waist hole, through hole, and coordinate with electromagnet 21, handle set 2-2 screw is fixed on door-plate 12 by pressing plate 4.

Handle cover 2-1 has the axle 2-12 of spring 25 by cover on it, the through hole be each passed through on handle set 2-2, card 20, gear 3 connects into entirety, and also at terminal surface screw 26 setting-up piece of axle 2-12, pad diameter is larger than bore, each part can not be deviate from, as shown in Figure 3.

Swivel nut 6 is weldingly fixed on side door frame 11 inwall just to spindle assemblies 7 place.

The two ends of connecting rod 1 sidewall connect upper and lower main door bolt 18,19 with screw, and the upper surface at two ends is connected with the door bolt up and down 14,16 of upper and lower connecting rod 13,17.

There is the installation screw be fixedly connected on connecting rod 1 at main shaft guide strip 24 1 edge; the soffit at another perpendicular edge is screwed slip tooth plate 5; its cross section is Z-shaped; the main shaft guide strip on slip tooth plate 5 limit there is long waist shaped chute 24-1; another edge side relative with there being installation screw has a link stopper 24-2; and the external part 21-1 conflicted on electromagnet 21, protection is closed main shaft guide strip behind the door and can not be moved.

Spindle assemblies 7 is multidiameter, and outer end is that screw mandrel 7-1 coordinates with the swivel nut 6 be fixed on side door frame 11, and centre is bearing rod 7-2, the bearing support 22 of mounting strap bearing 23 on bearing rod.Bearing support rotates together with spindle assemblies tight fit, and there is the cylindrical bar 7-3 of blind hole the inner for one end, the edge of the cylindrical bar other end is fixed a raised projection 7-4.The lower end of bearing rod is inserted in the blind hole of cylindrical bar through bearing, and for making bearing rod not pull out from cylindrical bar, connecting into rotating with lateral pin by bearing rod 7-2 and cylindrical bar 7-3 is integrally movable end, as shown in Figure 5.

Spindle drum 9 is fixed the screw-casing 8 peripheral wall having helicla flute 8-1, the cylindrical bar 7-3 of spindle assemblies 7 holds and inserts in screw-casing 8, and the projection 7-4 on it moves around along the helicla flute 8-1 on screw-casing 8.Namely spiral fluted length be the stroke of connecting rod movement.

There are opening 1-1 in centre position and the right edge of connecting rod 1 sidewall, on bearing rod 7-2 in the middle of the opening 1-1 insertion spindle assemblies that connecting rod is middle, connecting rod is clamped between screw mandrel 7-1 and bearing support 22, and the screw at bearing support two ends is fixed on the sidewall of connecting rod 1, as shown in Figure 6.

Be fixed on the soffit of connecting rod 1 with screw through the installation screw on main shaft guide strip 24 1 edge, and the long waist shaped chute 24-1 on main shaft guide strip is coordinated with limited post 15, limited post only moves in long waist shaped chute 24-1, restriction and main shaft guide strip connect into the moving range of overall connecting rod, limited post 15 is weldingly fixed on door-plate 12, slip tooth plate 5 fixing on main shaft guide strip engages with gear 3, as shown in Figure 7.

During use, to open box-frame door, first insert door lock hole 27 with key large stopper sheet 10 counterclockwise to be rotated 90 ° and leave connecting rod 1 and eliminate one and heavily insure, again correct password is inputted to coded lock (figure does not draw), electromagnet 21 is inhaled lower external part 21-1 and is retracted, touch also actuating card 20 to move right, at this moment the lower limb of card through hole departs from the contact with annular groove 2-11 on axle 2-12, then axle is unobstructed under the effect of spring 25, drive handle cover 2-1 to move to direction outside door-plate, at this moment operator just can hold handle cover 2-1 and carries out opening door operation.As shown in Figure 4, simultaneously because the external part 21-1 retraction of electromagnet can not stop moving left and right of main shaft guide strip, double insurance is namely turn eliminated.

With the handle cover 2-1 on hand clockwise direction turning handle, handle cover rotates and drives the gear 3 connecting into entirety with it to rotate, the sliding rack 5 engaged on main shaft guide strip 24 moves with it in the rotation drive of gear 3, connecting rod again by linking into an integrated entity with it, main shaft guide strip, drive spindle assemblies to door-plate 12, in side door frame 11, direction is moved, spindle assemblies 7 clockwise direction in screw-casing 8 is driven to rotate, swivel nut 6 in the screw mandrel 7-1 receding side doorframe 11 of simultaneously spindle assemblies 7 front end, in door-plate 12, direction is rotated, just safe cabinet door is opened, as shown in Figure 1.

On the contrary, to close the door, just with hand counterclockwise turning handle lid 2-1, counterclockwise rotated by handle cover 2-1 driven gear 3, drive the sliding rack 5 engaged with it to drive spindle assemblies 7 to move to direction outside door-plate, side door frame by the connecting rod 1 linked into an integrated entity with it simultaneously, namely spindle assemblies is driven counterclockwise to rotate in screw-casing, spindle assemblies also moves to direction outside door-plate, side door frame simultaneously, when the screw mandrel 7-1 of spindle assemblies front end screws in swivel nut 6, the door of safe is just locked, as shown in Figure 2.

Also available key inserts door lock hole 27, drives large stopper sheet 10 to rotate clockwise 90 ° with key, withstand connecting rod 1 do not make its again movement be one heavily to insure.

Finally with hand, handle cover is pushed away toward direction in door-plate 12, handle cover 2-1 is made not to be exposed at outside door-plate outward, simultaneously in the annular groove 2-11 of the through hole inlay card of card 20 on handle cover 2-1 axle 2-12, card 20 can not move, at this moment just safe can not be opened, connection coupling mechanism force between screw mandrel 7-1 and swivel nut 6 is large, and external force cannot prize, therefore use safety, reliable, theftproof is good.

Driven the connecting rod 1 be connected with main shaft guide strip 24 by sliding rack 5 by gear 3, and the spindle assemblies 7 be connected with connecting rod does rotary motion laterally to the inside and outside direction of side door frame 11.
