Abstract

The utility model relates to a security locking head, comprises a casing, a core body, a spring, a vertical billiards, a driving component, a shutter, a backboard and a steel lagging; because the vertical billiards is sheltered by the shutter and separated with the key hole, makes the master key of the thief can not touch the dial and then failure; the utility model adopts the smart structure that the vertical billiards and the transverse billiards are arranged in the inner core body of the key hole to form an interlinking protective billiards, and the right end of the transverse shutter is close to the front end of the billiards which is in the left of the former vertical billiards, making the front end of the newly additional billiards in the top of the shutter and the key hole are obstructed; because the gap between the casing and the core body is small, and the two ends are matched in concavo-convex shape, stopping the insert of the sheeting of the thief; the utility model makes the present method of opening the lock by the thief, greatly increases the anti-burglary function, and has low cost and strong in theft-protecting, will be applied to the burglar-proof padlocks used by every family.

Description

Anti-theft lock end

Affiliated technical field:

The utility model belongs to commodity, particularly be a kind of anti-theft lock end of pin tumbler lock.

Background technology:

At current this circumstance complication, technology prosperity, rhythm efficiently in the society, what perplex us every day is the safety problem of wealth, thing, your leak of the searching that some lawless persons often rack one's brains, utilize his your lock of superb technical opening, make your wealth, thing be subjected to stolen threat, at present, the various locks of domestic and international a lot of lockmaking manufacturer development mainly divide electronic safety lock and mechanical anti-theft lock two big classes.Electronic safety lock has: Contact Type Ic Card lock, magnetic card lock, ID kayser, induction IC card lock, coded lock etc., but cost is difficult to popularize on a large scale than higher.And the mechanical anti-theft lock kind is also many, and price is low, but theftproof is relatively poor; For example, general cylinder lock is made up of crust, housing, core body, lock nose, pellet shot from a slingshot, spring, connector key etc., after key inserts keyhole, the pellet shot from a slingshot displacement, the slit is unobstructed between core body and the housing, makes core body rotatable, connector is rotated, the lock nose is unclamped, lock is promptly opened; So have some master-hands that unblank in a few minutes even one minute, just can open, do not have the sense of security at all.

Summary of the invention:

To provide a kind of cost low order of the present utility model, and mechanical type is safer, the cylinder lock anti-theft lock end.

The purpose of this utility model be achieved in that specify as follows:

Tapered end is made up of housing, core body, spring, pellet shot from a slingshot, be characterized in the left side of original pellet shot from a slingshot, parallel establish at least 1 vertical pellet shot from a slingshot hole, pellet shot from a slingshot front end is wherein blocked by the pellet shot from a slingshot front end on horizontal shutter and original left side, and is obstructed with keyhole; Core body inwall in shutter and the keyhole axially parallel, its left end and keyhole connects as one, and its right-hand member is arranged in keyhole.

Establish horizontal pellet shot from a slingshot hole at least 1 on the core body in the keyhole above the shutter left end and on the corresponding housing, the pellet shot from a slingshot front end is approaching with vertical pellet shot from a slingshot front end in its hole, and is with blocked by shutter 8, obstructed with keyhole.

On the keyhole inner core-body and corresponding housing below the shutter, establish at least 1 following horizontal pellet shot from a slingshot hole parallel with last horizontal pellet shot from a slingshot hole, the pellet shot from a slingshot front end is arranged in keyhole in its hole.

The utility model has the advantages that and adopt structure cleverly; set up vertical pellet shot from a slingshot on the core body in keyhole; horizontal pellet shot from a slingshot and form the chain of rings ' protection pellet shot from a slingshot '; and laterally that pellet shot from a slingshot front end of shutter right-hand member and original vertical pellet shot from a slingshot left is close; pellet shot from a slingshot front end and keyhole that the shutter top is newly established are obstructed; make that existing to steal method for unlocking malfunctioning; strengthened its anti-theft feature greatly; and cost is low; the characteristics that theftproof is strong will be applied in the theftproof lock of huge numbers of families' use widely, as: the family expenses theftproof lock; bicycle theft-prevention; anti-theft lock for motorcycle etc. all can be used.

The utility model is to improve to form on the basis of existing cylinder lock as seen from Figure 1,5 pellets shot from a slingshot 15 of pellet shot from a slingshot 6 lefts are the same with existing cylinder lock among the figure, the pellet shot from a slingshot of setting up 6,7,9 and pellet shot from a slingshot 65 right-hand pellet shot from a slingshot 15 structures, the action principles also are identical, just the position difference; Pellet shot from a slingshot 6 is positioned at the left of pellet shot from a slingshot 15, and is vertical, parallel with pellet shot from a slingshot 15, and it is most advanced and sophisticated most advanced and sophisticated approaching with the pellet shot from a slingshot 7 that is arranged in pellet shot from a slingshot hole 13; Pellet shot from a slingshot hole 13 directions of pellet shot from a slingshot 7 are axially identical with keyhole 16, for laterally, are arranged in keyhole 16 inner core-bodies 2 and corresponding housing 1; Shutter 8 right-hand members are positioned at keyhole 16, and are most advanced and sophisticated approaching with the pellet shot from a slingshot 15 on the left side, make wherein perpendicular, laterally pellet shot from a slingshot and right-hand keyhole are obstructed; Shutter 8 directions are axially identical with keyhole 16, and its left end is fixedlyed connected with keyhole 16 inner core-bodies 2 inwalls; Pellet shot from a slingshot 9 is parallel with pellet shot from a slingshot 7, is positioned at the below of shutter 8, and its tip is positioned at keyhole 16; Between driving member 11 inner sidewalls and the core body 2 left end sidewalls is gear 17 interlocks.

All pellet shot from a slingshot holes shown in the figure, shutter, key are all in one plane.

The two ends in slit 4 are concaveconvex shape.

Vertical pellet shot from a slingshot 6 is one at least, also can be made as 2-3.

Laterally pellet shot from a slingshot 7 is one at least, can be made as 2-3.

Shutter 8 blocks pellet shot from a slingshot 7,9, makes itself and keyhole 16 obstructed, and the existing key of opening was steathily lost efficacy.Shutter 8 is one at least, also can be made as 2-3; Shutter 8 right-hand members can be cylindricality or abnormity such as rhombus or V-arrangement or curved surface shaped or multilayer, as long as all can with identical joining of key 3 contact portions coupling.

In order to reinforce tapered end and to block vertical pellet shot from a slingshot hole, upper and lower at tapered end, the right outside adds steel bushing 5; Add backstop 10 in the outside, tapered end lower-left, blocked horizontal pellet shot from a slingshot uropore simultaneously, make in tapered end and assemble.

The specific embodiment;

Because designing two ends between housing 1 and the core body 2 is that male and fomale(M﹠F) cooperates, in the whole assembling process of tapered end, must assemble according to a graded, at first core body 2 and gear `11 are fastened in the housing 1, place pellet shot from a slingshot, spring then, again back shelves 10 are radially inserted housing `1, will part locking about housing 1, at last that steel bushing 5 is the firm cover upper shell 1.

The process of unblanking;

Key 3 is inserted in the keyhole 16, key 3 top grooves and shutter 8 right-hand members coupling interleave, the extruding of key 3 upsides and end shape and all pellets shot from a slingshot that each is vertical, horizontal, make the slit between housing 1 and the core body 2 unimpeded, key 3, core body 2 is rotated, thereby driving member 11 is rotated, cause the lock nose to unclamp and reach the purpose of unblanking through gear 17.
