Description

Multi-functional rolling-gate pick-proof lock

The utility model belongs to a kind of rolling gate door lock.

Though existing rolling-gate anti-theft device is convenient, but still has following weak point: 1. can only unblank and can not shut with key.2. the pick-proof hook is straight hook, swings as rolling-gate, and the pick-proof hook will be deviate from the ground hook, and not reach antitheft purpose.3. the brake block of former lock is too many, complex structure, and cost is higher.

The purpose of this utility model is to create a kind of new rolling gate door lock, it is with key energy switch and latch automatically, simple in structure, theftproof performance good.

Main technical schemes of the present utility model is: multi-functional rolling-gate pick-proof lock mainly is made up of outer panels, inner cover plate, lock core, half of tooth, pinion, short tooth bar, long tooth bar, cylinder, pick-proof hook, angle bar frame, lock core, half of tooth and the engagement of long tooth bar are housed on the outer panels, and long tooth bar links by pinion and short tooth bar; Outer panels bottom connecting angle support, top is topped inner cover plate; Lock core sleeve has half of tooth and multi-functional shifting block, and block is equipped with on multi-functional shifting block next door.

The utility model has the advantages that: 1. this lock both can adopt the device that latches automatically to close the door, and available again key is closed the door, and the advantage that collects former rolling-gate lock, rolling-gate anti-theft device is one, and is easy to use.2. multi-functional shifting block can be reduced to one with former polylith shifting block, and is with low cost, install easily.3. the design of arc shaped hook is swung rolling-gate arbitrarily, and latch hook all is difficult to skid off, and is safe and reliable.

Be described further below in conjunction with the embodiment accompanying drawing.

Fig. 1 is the structural representation after the utility model removes inner cover plate;

Fig. 2 is the surface cover schematic diagram;

Fig. 3 is half of tooth schematic diagram;

Fig. 4 is multi-functional shifting block schematic diagram.

As shown in Figure 1, 2, this lock is mainly by outer panels 1, location pin 2, block 3, multi-functional shifting block 4, lock core 5, half of tooth 6, pinion 7, short tooth bar 8, angle bar frame 9, long tooth bar 10, cylinder 11, pick-proof hook 12, rivet 13, tension spring 14, internal control lock fabrication hole 15, pick-proof hook turning cylinder 16, block turning cylinder 17, pinion rotation axle 18, touching hook 19, touching hook locating slot 20, inner cover plate 21; Be equipped with on the outer panels 1 outside lock core 5, the lock core 5 and be with half of tooth 6 and multi-functional shifting block 4, block 3 is equipped with on multi-functional shifting block 4 next doors, half of tooth 6 and long tooth bar 10 engagements, and long tooth bar 10 links by pinion 7 and short tooth bar 8; Outer panels 1 bottom connecting angle support 9; Pick-proof hook 12 is fixed on the angle bar frame 9 by pick-proof hook turning cylinder 16, and 10 are provided with cylinder 11 and hole on the long tooth bar, and cylindrical hole is embedded on two location pins 2, and the cylinder 11 on the long tooth bar is arranged in the deep-slotted chip breaker of pick-proof hook.Pinion 7 is fixed on the outer panels 1 by rotating shaft 18, and short tooth bar 8 left ends have a borehole jack to go into to locate on the pin 2, and the other end passes the right side slotted hole of outer panels 1, and a touching hook locating slot 20 and corresponding with it touching hook 19 are arranged.Outer panels 1 has slotted hole, front that the steel sheet of several holes is arranged for a left side, last, right three side flangings, the right and lefts.Inner cover plate 21 is for the steel sheet of several holes is arranged, and is in the above topped.

Shown in Fig. 3,4, be placed in the half of tooth 6 on the lock core, in have one with the supporting hole 63 of lock core, outer rim has the plush copper 62 of an outside flanging, all the other are tooth 61.Be placed in lock core equally and be superimposed on have in the middle of the multi-functional shifting block 4 on the half of tooth 6 one with the supporting hole 44 of lock core, outer rim has two asymmetric plush coppers, wherein has one to be the plush copper 41 of inside flanging, another plush copper 43, by plush copper 41 places one insurance mouth 42 is arranged, it is corresponding with block 3.In the hook of the pick-proof hook 12 of this lock is circular arc, in case latch hook skids off easily.Be drilled with internal control lock fabrication hole 15 on the outer panels 1 of this lock, the inner cover plate 21, when lock is locked, after promptly long tooth bar 10 stretches out, because long tooth bar has right-angled bend, the indentation, there outer panels 1 of should turning, inner cover plate 21 there is internal control lock fabrication hole 15, insert rigid objects such as iron nail in this hole, make long tooth bar be difficult to return, so still can not unblank and open the door with key.

The course of work that this lock is opened rolling-gate is (during indoor opening the door):

Key is inserted core, be rotated counterclockwise 90 °, shifting block 4 drives half of tooth 6, and move on 10 planes thereby half of tooth rotates the long tooth bar of drive, and long tooth bar 10 drives short tooth bar 8 by pinion 7, and it is that rolling-gate two ends locking bolt is opened that the length tooth bar shrinks.And pin 11 moves by the plane of long tooth bar and drives pick-proof hook 12 and make the pick-proof hook break away from the ground hook on the long tooth bar, and the backing pin piece will rotate the insurance mouth 42 of shifting block around axle 17, turns clockwise 90 ° then to the original position key of back-outing.At closing time, key is inserted core, turn clockwise 90 °, shifting block 4 another plush coppers 43 will drive backing pin 3 and half of tooth 6 rotates, long tooth bar is done plane motion owing to half of tooth rotates, and long tooth bar is done plane motion by the short tooth bar of pinion drive, length tooth head launches, being rolling-gate shuts, be rotated counterclockwise 90 ° of keys to original position, backing pin enters insurance mouthful because of gravity falls automatically, be and lock the position, and the pin 11 of long tooth bar by the plane move drive on pick-proof hook 12 hooks hook, thereby reach the purpose of locking.This product also can latch automatically in addition, after rolling-gate is opened, because spring 14 1 ends of the pin of long tooth bar are pulled on pin 11, the other end is pulled on the left end of cover plate, when the lock rolling door was left behind, touching hook 19 was ejected touching hook groove 20 by ground, because the pulling force of spring, long tooth bar 10 is owing to the effect of pulling force launches, and short tooth bar 8 launches by pinion 7 transmissions.And pick-proof hook 12 also the pin 11 by long tooth bar drive and on the hook hook, and half of tooth 6 also passes through the drive of long tooth bar 10 and return, backing pin 3 falls automatically because of gravity, and reaches the purpose of locking.
