Fig. 1 is the inside partial structurtes schematic diagram of this safe-guard door lock.
Fig. 2 is in this safe-guard door lock and the structural representation of the oblique joining toggle mechanism of tongue dial sleeve.
The specific embodiment
But the specific embodiment of the safe-guard door lock of the utility model fast opening and closing as shown in Figure 1 and Figure 2.
But the structure of the safe-guard door lock of the novel fast opening and closing of this reality comprises lock body 1, supporting plate 6, oblique tongue dial sleeve 19, has the tapered end 7 of shifting block 8.Tiltedly tongue dial sleeve 19 is connected on the lock body 1 rotationally, is connected with master latch on the supporting plate 6.
Be fixed with a pivot 4 in lock body 1, be provided with pilot hole 16 on its direction of motion of described supporting plate 6 upper edges, described pivot 14 is plugged in the pilot hole 16 with gap.Also be provided with a main tongue shifting block 5 in lock body 1, main tongue shifting block 5 is provided with pivot hole 41, and pivot hole 41 is socketed on the pivot 4 with gap.Main tongue shifting block 5 is provided with the projection 17 that is connected as a single entity with it, projection 17 is provided with on the main tongue shifting block 5 prejudicially, corresponding position, position with described projection 17 on supporting plate 6 is provided with breach 18, projection 17 is plugged in the breach 18, the size of breach 18 is greater than the size of projection 17, so that projection 17 has certain rotation surplus in breach 18.
Also be provided with on oblique tongue dial sleeve 19 and can follow the main unlock chip 2 that oblique tongue dial sleeve 19 rotates together, link by a master connecting-rod 3 between main unlock chip 2 and the main tongue shifting block 5, the two ends of master connecting-rod 3 are hinged on respectively on main unlock chip 2 and the main tongue shifting block 5.One end of one secondary unlock chip 20 is hinged on the main tongue shifting block 5, and the pin joint on main tongue shifting block 5 lays respectively at the both sides of above-mentioned pivot 4 to secondary unlock chip 20 at pin joint on the main tongue shifting block 5 and master connecting-rod 3.
The other end of secondary unlock chip 20 is provided with the slide opening 201 with certain-length size, is fixed with a pilot pin 13 in lock body 1, and pilot pin 13 is plugged in the described slide opening 201 with gap.Be provided with outstanding convex body 9 at secondary unlock chip 20 near on the side of tapered end 7, the size of convex body 9 should guarantee that the shifting block 8 on the tapered end 7 can contact with it when rotating, and that is to say when shifting block 8 rotates, and shifting block 8 can drive secondary unlock chip 20 motions by convex body 9.
The elastic force that is provided with first torsion spring, 15, the first torsion springs 15 between secondary unlock chip 20 and lock body 1 can be pressed to tapered end 7 to the other end of secondary unlock chip 20.
Stacked successively from inside to outside lock banking stop 12 and compressing tablet 10 on secondary unlock chip 20, lock banking stop 12 is approximate V-shaped, and the knuckle place of lock banking stop 12 and an end of compressing tablet 10 are hinged on the secondary unlock chip 20 versatilely by rivet.Its length direction of compressing tablet 10 upper edges is provided with slotted hole 11, and slotted hole 11 is socketed on the pilot pin 13 with gap.The both ends of lock banking stop 12 are provided with second torsion spring 14 near tapered end 7 between lock banking stop 12 and lock body 1.Lock banking stop 12 is provided with V-arrangement seam 121 away from an end of tapered end 7, drive main tongue shifting block 5 and make locking bolt stretch out the outer rear flank of lock body 1 fully when shifting block 8 makes secondary unlock chip 20, under the effect of described second torsion spring, 14 elastic force, described seam 121 is connected on the outer peripheral face of described pilot pin 13.After seam 121 is connected on the pilot pin 13, after the power that master latch is applied on its direction of motion,, improved the anti-theft effect of this theftproof lock because the reaction force between lock banking stop 12 and the pilot pin 13 makes master latch be difficult to be advanced in the lock body 1.
But the theftproof lock of this fast opening and closing is locking or during open operation, it can pull the Internal handle that is arranged on the oblique tongue dial sleeve 19, making main unlock chip 2 drive main tongue shifting block 5 rotates, main tongue shifting block 5 utilizes projection set it on 17 and by supporting plate 6 the master latch realization is stretched out or the action of indentation lock body 1 when rotating.It also can utilize key that the shifting block 8 on the tapered end 7 is rotated, thereby by the convex body 9 on lock banking stop 12 or the secondary unlock chip 20, drives main tongue shifting block 5 and rotate, thereby makes master latch realize stretching out or the action of indentation lock body 1.
