Adorn automatic multi-faceted door lock outward
The utility model is the rim lock that a kind of urban and rural residents room is used, and belongs to hardware machinery, particularly be the outer automatic multi-faceted door lock of adorning.
The rim lock that existing market is sold generally has only a side that dead bolt is arranged, i.e. folk prescription position door lock, thereby its theftproof performance is relatively poor.General rim lock from outdoor door is closed after, door lock is not lived, just one of them movable dead bolt enters in the dead bolt hole, at this moment outdoor people must take out key and fill in the tapered end, and the rotation lock gall stretches out other one or two dead bolt from lock housing, enter in the doorframe locked cock hole, at this moment just locking is extracted key then out and is left, and this has to the people a kind ofly is inconvenient to feel.
The purpose of this utility model is to make a kind ofly to adorn automatic multi-faceted door lock outward, thereby overcomes two weakness of above-mentioned general door lock, improves theftproof performance and has automatic closing function.
The utility model is design like this: general door lock one side only is with one or two dead bolt.For strengthening anti-theft capability, at first the side dead bolt is increased to three, structurally adopt the new design of closing dead bolt automatically simultaneously, one of them dead bolt is made special structure, tripping spring promptly is installed in the above, make the movable dead bolt that becomes left and right sides play.When three dead bolts all enter in the lock housing, after as long as first special movable dead bolt is subjected to the external force collision, the afterbody of this dead bolt clashes into the bump head of " seven " font fixed plate one end immediately, the hook hand of the fixed plate other end is thrown off from the notch of slide plate, and a tripping spring forces slide plate to advance, and all enters in the dead bolt hole thereby make with the slide plate one dead bolt that coexists, at this moment lock promptly cuts out, irreversible, removed the trouble that outdoor people will close door again with key from, very convenient.The another one structure is that the gear shaft at the lock housing center passes upper and lower two the identical Knucle-gears of ining succession respectively of keep plate, wherein go up the Knucle-gear both sides flat tooth bar of respectively ining succession, and each flat tooth bar itself is exactly the flat dead bolt that passes lock housing, one is the last flat dead bolt that stretches out upward, one is the following flat dead bolt that stretches out downwards, thereby make this lockset that the multi-faceted function that locks door leaf be arranged, strengthened its theftproof performance.
Advantage of the present utility model is as follows: one, novel in design, compact conformation, lock body is solid and reliable, and is easy for installation, uses flexibly again, and is provided with back locking function.Have pick-proof, the anti-high theftproof performance that unloads.Two, have the function of closing automatically, remove the trouble that outdoor human key is closed from, easy to use.Three, be equipped with stop button.After three dead bolts stretch out, stop button to be pushed to, three dead bolts can't indentation in lock housing, makes door play a part to insure thereby reach; When three dead bolts shrink, stop button is pushed, three dead bolts can't be protruding, thereby reach the state of being left unlocked or unlatched.
Further specify structure of the present utility model below with reference to the accompanying drawings: the structural front view that accompanying drawing 1 is analysed and observe for the utility model branch; Accompanying drawing 2 is a backsight sketch of the present utility model.We are as can be seen from accompanying drawing: outside adorn automatic multi-faceted door lock, form by tapered end 1, key 2, base plate 3 and box-like lock housing 4 etc.One of its design feature is that the gear shaft 5 at box-like lock housing 4 centers passes rectangle keep plate 6 and connecting respectively and go up Knucle-gear 7 and following Knucle-gear 8, last Knucle-gear 7 both sides are respectively connecting left gear bar 9 and right tooth bar 10, one end of left side tooth bar 9 is the last flat dead bolt 11 that stretches out lock housing 4 upper sides, and an end of right tooth bar 10 is the following flat dead bolt 12 that stretches out lock housing 4 downsides.Two of its design feature is slide plates 13 that " L " shape has been installed on the right side of box-like lock housing 4, slide plate 13 1 ends are connecting the upper lock tongue 14 that passes lock housing 4 right hand hay cutter faces, middle dead bolt 15 and following dead bolt 16, upper lock tongue 14 is by bullet-shaped lock tongue 17, tubular dead bolt tail 18 and columnar shell 19 are formed, coil tension spring 20 also is installed on the periphery of dead bolt tail 18, braking spring 21 has also been installed at middle part at middle dead bolt 15, one flat tooth 22 is arranged below the other end of slide plate 13, following Knucle-gear 8 on it and the gear shaft 5 tightly meshes, and there is a notch 23 upper end of slide plate 13; The fixed plate 24 of " a seven " font also is installed above lock housing 4, and the left end of fixed plate 24 has inside inverted hook hand 25, and the right-hand member of fixed plate 24 has outwards upright bump 26, is with tower spring 27 on top one column cap of fixed plate 24.Three of its design feature is handles 28 that the circular arc that is connected with gear shaft 5 is arranged in the positive back of lock housing 4, in the lower-left side rectangular stop button 29 is installed.Four of its design feature is that the insurance shift fork 30 of an annular also has been installed on last Knucle-gear 7 planes, and at insurance overlapping again dome 31 of two annulus on the shift fork 30, dome 31 is bolted on the keep plate 6 by two again.
Below we continue to see mode of occupation of the present utility model.When rim lock by after installing and using book and installing, can know: the circular arc handle is connecting gear shaft, rotate handle, the gear shaft rotation, and drive upper and lower two Knucle-gears rotation, at this moment, the tooth bar that following Knucle-gear is meshing on the slide plate moves, and makes side three dead bolt indentation lock housings, when slide plate arrives maximum position, the downward hook hand of fixed plate enters the slide plate notch slide plate is blocked, and three dead bolts maintain static.At this moment two flat teeth going up the Knucle-gear engagement also are retracted in lock housing, make in the also indentation lock housing of upper and lower flat dead bolt, and door promptly is opened.When at closing time, the lock tongue of upper lock tongue is once collision, it is very in the rewind down indentation lock housing, moment is clashed into the bump head of the fixed plate in left side, under the effect of tower spring, the hook hand of the fixed plate other end is thrown off from the notch of slide plate upper end, under the braking spring effect of slide plate in middle dead bolt, skid off to the right, going up of being attached thereto of side three dead bolts and upper and lower bolt, the hyoplastron of locking are released lock housing again, door is locked, the people promptly has AutoLock feature, if outdoor, just need not lock a door with key again, at this moment door locks, and is fool proof.And for example for the purpose of the insurance, can clockwise rotate key 360 degree, dial-out can be with back locking function.This utility model has automatic multi-faceted function, is a kind of novel rim lock, will obtain numerous residents' welcome.
