See also Fig. 1,
The first step: tapered end 3 rivetings are gone into to lock shell 1 the middle part the mouth 14 in;
Second step: dead bolt 71 rivetings are gone in the hole 22 of first movable block 221, first movable block 221 is put into an end of locking shell 1, dead bolt 72 rivetings are gone in the hole 22 of second movable block 222; Second movable block 222 is put into the other end of lock shell; The aspect that two movable blocks are placed is opposite, connecting rod (731,721) is interted from the hole (151,152) of the lock shell one side first shell face respectively pass the hole 21,23 on first plate, and the hole 21,23 from second plate passes on the hole 151,152 that penetrates the second shell face again; The two ends of connecting rod and the first shell face and the welding of the second shell face is fixing; Again connecting rod 732,722 is inserted from the hole 154,153 of the first shell face respectively, pass the hole 23,21 on the first plate face, pass in the hole 23,21 from the second plate face again; Pass in two the holes 154,153 from the second shell face; Connecting rod two ends and the first shell face and the welding of the second shell face is fixing, and like this, first movable block and second movable block just are fixed on the two ends of lock shell; And can in the lock shell, move along connecting rod, second movable block, 222 placement directions are opposite with first movable block;
The 3rd step: an end of first elastic device 91 is stuck on the projection 24 of first movable block, and the other end is stuck on the projection 131 of lock shell 1, and an end of second elastic device 92 is stuck on the projection of second movable block 29, and the other end is stuck on the projection 132 of lock shell 1;
The 4th step: with screw 51 hole 63 of the first gear pull bar, 61 1 ends and the hole 25 of first movable block, 221 1 ends are fixed together, the hole 63 of the second gear pull bar, 62 1 ends and the hole 25 of second movable block, 222 1 ends are fixed together with screw 52;
The 5th step: gear pull bar 61 is put into groove 31, gear pull bar 62 is put into groove 32, place gear 4, snap in nibbling in the mouth 64 of gear pull bar (61,62) to the tooth of gear 4 respectively in the inboard of tapered end 3;
The 6th step: lock core 9 is placed in the outside at tapered end 3, with screw gear 4 tapered ends 3 lock cores 9 is fixed together, and gear 4 can be rotated with the rotation of lock core 9;
The 7th step: useful screw will be locked shell 1 through the hole 11 at two ends on the 3rd shell face 113 and be fixed on the position of setting on the switchboard door;
The 8th step: an end 82 of hook 8 is screwed into cabinet, and the position of hook 8 is corresponding with the position and the quantity of quantity and dead bolt, whole lock body installation.
First embodiment:
Key is put into lock core 9 to rotate; The rotation of lock core 9 has driven gear 4 and has rotated; Gear 4 drives the first gear pull bars 61 and moves to the centre from both sides with the second gear pull bar 62, and at this moment the first gear pull bar, 61 pulling first movable blocks 221 and the second gear pull bar 62 spur second movable block 222 and move to the centre from both sides, first movable block 221 when move the centre projection 24 on first movable block 221 along with moving to the centre; And the projection 131 on the 3rd shell face 113 is fixed; Projection 24 and projection 131 be elastic device 91 compressions like this, and the projection 29 on second movable block 222 is along with moving to the centre when move the centre for second movable block 222, and the projection 132 on the 3rd shell face 113 is fixed; Projection 29 compresses elastic device 92 with projection 132; First dead bolt, 71 second dead bolts 72 close the Over-The-Counter door also along with first movable block 221 and second movable block move to the centre from both sides, unclamp key; First movable block 221 resets under the restoring force effect of first elastic device 91, second movable block 222 return under the effect of the restoring force of second elastic device 92; Dead bolt is locked in the groove 81 of hook 8, at this moment cabinet door lock is lived, lock the sectional drawing of hook like Figure 15 for dead bolt.When opening the door; Key, gear 4 drive the first gear pull bar, 61 second gear pull bars 62 and move to the centre, and the first gear pull bar 61 drives first movable block 221, the second gear pull bar 62 and drives second movable block 222 and move to the centre from both sides; Dead bolt moves to the centre from both sides with movable block; At this moment dead bolt breaks away from the groove 81 of hook 8, and the cabinet door is opened, accomplish once open close the cabinet door.
Second embodiment:
Also can only need firmly close the door at closing time, because the outside of dead bolt 71 is inclined-planes 711 without key; And the outside of hook 8 one side also is inclined-plane 83, and this two inclined-plane is corresponding, because hook 8 is fixed; And dead bolt 71 is movable, therefore, and under the effect of external force; Dead bolt 71 711 moves to the centre along the inclined-plane, drives whole movable block simultaneously and moves to the centre, when dead bolt 71 moves, elastic device is compressed; Until whole dead bolt move on to the hook groove above, at this moment elastic device resets, and under the effect of elastic device restoring force, dead bolt is locked in the groove of hook cabinet door lock is lived; Lock the sectional drawing of hook like Figure 15 for dead bolt, it is identical with first embodiment to open the door, and the Kai that accomplishes a cabinet door closes.
Though the present invention with embodiment openly as above; Right its is not in order to limit the present invention; Has common knowledge the knowledgeable in the field under any; Do not breaking away from the spirit and scope of the present invention, when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the aforesaid right claimed range person of defining.
