Description

Straight-through ball lock head and key

Technical field

A kind of skill type that prevents is unblanked, and has the ball lock head and the key of straight-through pellet shot from a slingshot.

Background technology

In the various cylinder locks of flat key that are widely used at present, be divided into two kinds of locks basically.A kind of is the pellet shot from a slingshot axis cylinder lock consistent with the key cross section of lock, and this kind lock is easier to open concerning the people who unblanks specially.Another kind is the pellet shot from a slingshot axis cylinder lock vertical with the key cross section of lock, and this kind locking manufacturing accuracy is higher, and difficulty is opened concerning the people who unblanks specially.For solving, therefore need improve ball lock head and key by other people this difficult problem of unblanking.

Summary of the invention

The purpose of the utility model is a kind of straight-through ball lock head and key that can prevent that other people from unblanking of design.The pellet shot from a slingshot axis that should lead directly to ball lock head is vertical with the key cross section, and its key and keyhole have

type and two kinds of patterns of

type.Existing ball lock head has several groups by the pellet shot from a slingshot assembly that descends pellet shot from a slingshot, last pellet shot from a slingshot, pellet shot from a slingshot spring to constitute; Insert good key, have the following pellet shot from a slingshot of a correspondence to be in contact with it respectively on each tooth position of key, the upper surface of pellet shot from a slingshot is concordant with plug face under all, and key is unblanked.Existing pellet shot from a slingshot hole with lock core is counted from outside to inside and is first, second ... Lower marble hole, it is corresponding with it that what communicate is first, second ... Last pellet shot from a slingshot hole, its position is called first, second ... The bullet position.

The utility model has been done following improvement to existing ball lock head and key: 1, pellet shot from a slingshot under at least one is changed into straight-through pellet shot from a slingshot; The definition of straight-through pellet shot from a slingshot is in the lower marble hole of lock core, to put into pellet shot from a slingshot; The pellet shot from a slingshot bottom contacts with the bottom surface, upper surface concordant with plug face (that is to say in lower marble hole ' gigantic '), and this pellet shot from a slingshot just is straight-through pellet shot from a slingshot.2, do not have through hole on the tooth position of existing key, the tooth position of corresponding straight-through pellet shot from a slingshot on the key of the utility model is a through hole, and straight-through like this pellet shot from a slingshot bottom is passed through hole and contacted with the bottom surface.After above improvement, straight-through ball lock head and key have just been become.

The anti-principle of unblanking of straight-through ball lock head is such: when having only a straight-through pellet shot from a slingshot, its position is preferably in the second or the 3rd bullet position, and the following pellet shot from a slingshot of its front is the protection to straight-through pellet shot from a slingshot.Straight-through pellet shot from a slingshot is in the process of opening the lock with the key; Rotate in lock core hole with lock core; The gap very little (preferably being controlled in 0.04 millimeter) of straight-through pellet shot from a slingshot and lock core hole, and other people the unblank thickness of instrument of usefulness is much bigger than this gap, so after unlocking tool passes through to lead directly to pellet shot from a slingshot; To lead directly to pellet shot from a slingshot and raise and get into to go up in the pellet shot from a slingshot hole, lock core is pinned and can not rotate by straight-through pellet shot from a slingshot; Straight-through pellet shot from a slingshot has been blocked the passage of unlocking tool, reaches the purpose that prevents that other people from unblanking.To preventing most people that unblank specially, a straight-through pellet shot from a slingshot has been arranged just; To extremely indivedual top people that unblank, two straight-through pellets shot from a slingshot have been arranged just (the straight-through pellet shot from a slingshot that also has new nothing wearing and tearing is good).

Design is achieved in that

Straight-through ball lock head and key; Its key and keyhole are that this pattern is (because of the key of this pattern is regardless of positive and negative; The two sides is equally used; Thereby use more conveniently, use also more extensive).Straight-through ball lock head has a tapered end, has a lock core hole, tapered end top to have a row to go up the pellet shot from a slingshot hole in the middle of the tapered end, pellet shot from a slingshot, pellet shot from a slingshot spring is housed in the pellet shot from a slingshot hole on each, and with plug they is sealed.Lock core is housed in the lock core hole, a keyhole is arranged on the lock core, row's lower marble hole is arranged on the perpendicular direction, have the straight-through pellet shot from a slingshot lower marble hole of packing at least, the pellet shot from a slingshot down of packing in remaining lower marble hole.Insert good key, the tooth position of corresponding straight-through pellet shot from a slingshot is a through hole on the key, and straight-through pellet shot from a slingshot bottom is passed through hole and contact with the bottom surface, the upper surface that leads directly to pellet shot from a slingshot with remaining under the upper surface of pellet shot from a slingshot concordant with plug face, key is unblanked.

Compared with prior art, the straight-through pellet shot from a slingshot in the utility model has been blocked the passage of unlocking tool, reach the purpose that prevents that other people from unblanking, thereby theftproof performance improves greatly.
