Description

The stealthy combination padlock of mechanical type and the key of unblanking

One, technical field

The utility model relates to the stealthy combination padlock of mechanical type and the key of unblanking, and is particularly useful for all kinds of safety cabinets and security door, also is applicable to all kinds of automotive door, motorcycle, bicycle, strongbox and all kinds of portable lock.

Two, background technology

Traditional mechanical digital lock is owing to exist the defective of interlock between parts, cause digital easy stolen survey, for addressing this problem, producer has adopted the way of additional cylinder lock to remove to block the combination padlock clamp, to prevent to steal the digital gear of survey, but cylinder lock is also opened by the expert easily, can not tackle the problem at its root; Its two, traditional combination padlock must positive and negatively repeatedly dial change multi-turn just can finish sign indicating number tuning, and low precision, it is higher to open fault rate; Its three, traditional combination padlock must have light to operate.The coded lock of external is not only digital besides steals survey easily, and the digital shelves wheel of its exposure is also very easily pressed from both sides broken or destroys, and seldom uses now; And the figure case shifting block pin on its digital wheel of built-in coded lock is certainly existing diameter dimension, shifting block pin in tuning to sign indicating number on each digital shelves wheel is superimposed and will produces a bigger error size, because this technical defective, the digital position of not only limiting on coded lock digital shelves wheel sheet quantity and the digital shelves wheel sheet is difficult to increase, also caused to sign indicating number the trouble of this error amount that must add in tuning, also has the combination padlock that occurs in the recent period, since have a plurality of action bars stretch out the door or cabinet outdoors, carry out a bar single piece type to sign indicating number, therefore door is gone up and must be beaten a plurality of holes, if at will destroy an action bars, just can't unblank.

Three, summary of the invention

In view of the deficiency that prior art exists, the purpose of this utility model provide between a kind of compact conformation, no shifting block, parts by combined-control tuning device coordinate control easy lock, easily open, the mechanical type stealth combination padlock of good anti-theft effect and the key of unblanking.

The technical scheme that its technical problem that solves the utility model adopts is: the stealthy combination padlock of mechanical type, it is made of barrel-type casing and the digital shelves wheels and the combined-control tuning device that are located in this housing, barrel-type casing has a square gap vertically, the barrel-type casing inwall is provided with 3 bar shaped shape arc grooves vertically, barrel-type casing top is provided with joint control and opens and closes thumb wheel, and the bottom is provided with key hole lock top.Described digital shelves wheels have the key through hole by a plurality of centers and are spaced and constitute with the digital shelves wheel of dialling board slot, number shelves wheel dividing plate; Sliding sleeve and back-moving spring that combined-control tuning device opens and closes thumb wheel and stationary rack by the joint control latch bar that inserts the housing opening position, with the joint control of its interlock constitute.Described digital shelves wheel is made up of locating wheel and the core wheel that is located at the locating wheel inner ring, locating wheel internal diameter circumferential wall is provided with a plurality of digital location deep-slotted chip breakers and core is taken turns spacing deep-slotted chip breaker, the locating wheel external diameter is provided with shoulder, has a square three-way groove that matches with joint control latch bar and a plurality of square shallow slot on the shoulder nose circle face; Be interval with 3 angles spring steel ball positioning component identical, that match with the digital location of locating wheel endoporus deep-slotted chip breaker on the core wheel periphery.The bar shaped arc groove that the barrel-type casing inwall is provided with vertically has 3, and the angle α between 3 bar shaped arc grooves is 120 °; Have a square three-way groove that matches with joint control latch bar on the digital shelves wheel dividing plate external diameter, and be provided with the arc arch that matches with barrel-type casing inwall bar shaped arc groove.It is the short cylinder that the middle part has shoulder that joint control opens and closes thumb wheel, center, top is provided with the screw hole that the shifting block of unblanking is installed on it, the center of going to the bottom is provided with keyhole, has a gap that matches with the joint control latch bar facewidth on the shoulder, and the angle β of gap both sides and axis symmetry is 100 °～150 °; Joint control latch bar is provided with a plurality of square shaped teeth, is cambered surface as the bottom surface of first square shaped teeth of dop, and the number of tooth is corresponding with the number that digital shelves wheel is provided with.Radially be provided with the key card loop mapping in the keyhole of described lock top and bump the rotation of pearl and key pearl is bumped in the unidirectional location of sign indicating number, upper surface, lock top is provided with vertically presses the power spring steel ball assembly that stagnates, and key hand-hole place, lower surface is provided with hard alloy steel keyhole sheath.

Open the key of the stealthy combination padlock of mechanical type: key body is one ' aciculiform ' elongated cylinder, have many graduation marks that angle is identical and parallel with axis on the elongated cylinder cambered surface, graduation mark is provided with a plurality of telescopic arcs and dials plate, the key body afterbody is provided with positioning ring groove, and the positioning ring groove below is provided with the location half slot of rotation to sign indicating number.

The beneficial effect of the stealthy combination padlock of the utility model mechanical type and the key of unblanking is: a plurality of digital shelves wheels and the accurate compact sealing of combined-control tuning device ground collection dress are one, and make its standardization, integrated, it is ever-changing that the lockset password setting can reach, setting for password, need not as other coded lock, take lockset apart or establish flat nail and carry out, need only will mix up in " fool " lockhole when key is inserted in open position of dialling the plate bit combination clockwise or to rotate counterclockwise a week more, moment promptly is provided with finishes one group of password.And realized the uniting and adjustment control that sign indicating number moves and breakdown action definitely separates is surveyed password to stop to steal, integrated lock core can be supporting with all kinds of locksets simultaneously, the supporting key that has correspondence to unblank of this combination padlock.Because digital shelves wheel is gone up no shifting block, the gap of moving about of adding up between wheels is very little, thereby many groups can be set, the size of establishing close amount of password increases along with the increase of digital wheels, when the digital shelves wheels of collection dress reached a figure case on 9 groups, each digital shelves wheel and are 12, it " stored " total amount digital and will reach 9 ¹², promptly 5,100,000,000 groups, anti-theft effect is fairly obvious.Its compact conformation, volume is little, and the intensity height can realize that the moment of coded lock under need not the light situation open, its cost of production is low, be difficult for being damaged, long service life has very high fail-safe, and key unlocking is simply easy, can indiscriminately ad. as one wishes change on the key body arbitrarily or the position of a plurality of groups of plates, thereby increase the close variation of establishing of combination padlock, strengthen its security personnel's characteristic, this lockset has practicality widely.
