Description

Ball lock head

The utility model relates to a kind of lockset, especially the lock gall of lockset inside.

Tapered end is of many uses, constantly weeds out the old and bring forth the new.Occurred a lot of spring type tapered ends in the market, this locks because of its particular structure, opens and be difficult for being made so-called " omnipotent spoon " by other people, has excellent antitheft function.But its operation is more, complex structure, and cost is higher.

The purpose of this utility model is to provide the ball lock head that a kind of structure is comparatively simple, cost is lower, safety is stronger.

The utility model is achieved in that ball lock head, comprises tapered end shell, lock core, some pellets shot from a slingshot, little spring and key etc., and the key hole is arranged on the lock core, and some spoons of teeth are arranged on the key face; Position vertical with the key face on the lock core has bullet groove, and the vertical position corresponding with bullet groove has the groove hole that communicates with bullet groove; Be furnished with pellet shot from a slingshot and little spring in the bullet groove, after key inserts, have corresponding pellet shot from a slingshot to match on the position of corresponding spoon tooth with it, fluted on the pellet shot from a slingshot; Groove is equipped with card on the hole, is provided with shell fragment in the middle of card and the groove hole; On the bullet groove opening of plug face, be provided with envelope and press the mounting of little spring and pellet shot from a slingshot.

Two row's spoon teeth are arranged on the key face, two row's pellets shot from a slingshot are arranged on the corresponding position.

There is little spring on the pellet shot from a slingshot top, and both are fixed in the bullet groove, and the pellet shot from a slingshot middle part is fluted.

Groove hole inner one-tenth stairstepping, deep-seated communicates with bullet groove.

Card becomes " L " type, and an arm stretches into groove hole deep-seated, props up pellet shot from a slingshot; One arm covers on shallow position, groove hole, is provided with shell fragment between the two.Card stretches into an arm of groove hole deep-seated, and its top has the selenodont teeth to prop up the round wall of pellet shot from a slingshot.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the of the present utility model structural representation of key after inserting.

Fig. 2 is B-B sectional view of Fig. 1.

Fig. 3 is the structural representation of lock core.

Fig. 4 is the structural representation of card of the present utility model.

The utility model is achieved in that ball lock head, comprises tapered end shell 1, lock core 2, some pellets shot from a slingshot 25, little spring 24 and key 3 etc., and the key hole is arranged on the lock core 2, and some spoons of teeth are arranged on the key face; Position vertical with the key face on the lock core has bullet groove 4, and the vertical position corresponding with bullet groove has the groove hole 5 that communicates with bullet groove 4; Be furnished with pellet shot from a slingshot 25 and little spring 24 in the bullet groove, inserting at key on the position of back corresponding spoon tooth has corresponding pellet shot from a slingshot to match with it, on the pellet shot from a slingshot fluted 26; Groove is equipped with card 6 on the hole, is provided with shell fragment 7 in the middle of card and the groove hole; On the bullet groove opening of plug face, be provided with envelope and press the mounting 8 of little spring and pellet shot from a slingshot.

There is little spring on the pellet shot from a slingshot top, and both are fixed in the bullet groove, and pellet shot from a slingshot middle part periphery is fluted.

Card becomes " L " type, and an arm stretches into groove hole deep-seated, props up pellet shot from a slingshot; One arm covers on shallow position, groove hole, is provided with shell fragment between the two.Card stretches into an arm of groove hole deep-seated, and its top has selenodont teeth 9 to prop up the round wall of pellet shot from a slingshot.

As shown in Figure 2, pellet shot from a slingshot is cylindrical, and the middle part is fluted, and its groove is a peripheral groove, so can conveniently install.

As shown in Figure 4, the card of ball lock head becomes " L " type, and bossed teeth on the arm, teeth because the tooth position leans against the thicker position of pellet shot from a slingshot, so another arm is given prominence to the core of unblanking, cause obstruction power before key inserts; After key entered, teeth leaned against the fine positioning of pellet shot from a slingshot, and another arm just can be absorbed in the groove hole, thereby no longer hindered the rotation of lock core.

Ball lock head is not before key inserts, and pellet shot from a slingshot is sagging, and the card deeply front end teeth on one side withstands pellet shot from a slingshot, and card makes lock core not rotate in the another side projection of lock core external surface, thereby can't open.After key inserted, the key front end was thinner, jack-up pellet shot from a slingshot one by one, pellet shot from a slingshot rises, this moment pellet shot from a slingshot with the groove that the position is a pellet shot from a slingshot that contacts of card, card decline thus no longer includes obstruction power to the rotation of lock core, thereby can open tapered end.

The utility model has the advantage of: easy for installation, cost is low, security is better.
