The specific embodiment
Be described in further detail below in conjunction with Figure of description and specific embodiment tapered end and key thereof a kind of cylinder lock with balls of the utility model.
With reference to the accompanying drawings 1, the tapered end of a kind of cylinder lock with balls of the utility model comprises lock housing 6, lock gall 5, and described lock gall 5 centers have keyhole 12.
Directly over the described keyhole 12, top-down 6 arrangements top surface micropyle 13 in line that offers on lock housing 6 and the lock gall 5, the bottom of described top surface micropyle 13 is communicated with keyhole 12, is disposed with sealing bead 1, spring 2 in it, goes up hoodle 3 and lower pellet 4.
Shown in accompanying drawing 1 and accompanying drawing 4, on the lock gall 5 in described keyhole 12 left sides from outside to inside the length direction along lock gall 5 have a locating slot 9, be provided with 5 hoodle holes 15 between described locating slot 9 and the keyhole 12 along the bottom land direction word order of locating slot 9, the top closure in described hoodle hole 15 is in lock gall 5, and its bottom is communicated with keyhole 12.With reference to the accompanying drawings 3, corresponding each hoodle hole 15 of the bottom land of described locating slot 9 offers 5 through holes 11, to be communicated with locating slot 9 and hoodle hole 15.
Be provided with a side positioning bead 10 in the described locating slot 9, shown in 8,9,10, described side positioning bead 10 is strip with reference to the accompanying drawings, and its inboard has 5 cylindrical protrusions 19, and the outside of described side positioning bead 10 is a cross section triangle rib 23 triangular in shape.
With reference to the accompanying drawings shown in 1,4,6,7, be provided with a side hoodle 8 and a side spring 7 in the described hoodle hole 15, described side hoodle 8 is cylindrical, through hole 11 places of corresponding locating slot 9 bottom lands are provided with a circular blind hole 17 on its side, the projection 19 of described side positioning bead puts in hoodle hole 15 by the through hole 11 of locating slot 9 bottom lands, and can embed in the blind hole 17.The top of described side hoodle 8 is provided with a groove 16, and described side spring 7 places in the groove 16, and its top withstands on the closed top end in hoodle hole 15.Also respectively be provided with a square fin 18 on the dual-side of described side hoodle 8.The inner wall shape in described hoodle hole 15 and the profile of side hoodle 8 are complementary, and square fin 18 places at corresponding side surface hoodle 8 are provided with the groove that is complementary with square fin 18, side hoodle 8 can snap in just in the hoodle hole 15 and can not rotate freely like this, thereby blind hole 17 aligned through holes 11 that guaranteed side hoodle 8 can be advanced and retreat side positioning bead 10 therein freely.
With reference to the accompanying drawings 1,2, the notch place of corresponding locating slot 9 offers a side channel 14 on described lock housing 6 inwalls, and the triangle rib 23 of described side positioning bead 10 can embed in the side channel 14.
With reference to the accompanying drawings 11, the end face of the key 20 that is complementary with described tapered end is provided with end face key tooth 21, and its side is provided with the lateral surface key tooth 22 that a row and side hoodle 8 are complementary.
During use, before key 20 does not insert, thereby the hoodle of end face falls to blocking lock gall 5 and lock housing 6 from end face, and side hoodle 8 falls under the effect of side spring 7 simultaneously, make its blind hole 17 and through hole 11 dislocation, thereby the triangle rib 23 of side positioning bead 10 is snapped in the side channel 14, therefore block lock gall 5 and lock housing 6 from the side.
After inserting key 20, the end face key tooth 21 jack-up lower pellets 4 of key 20 are withdrawn in the lock housing 6 hoodle 3, thereby make the end face release.Simultaneously, the lateral surface key tooth 22 of key 20 is jack-up side hoodle 8 from the bottom up, and blind hole 17 is alignd with through hole 11, and 10 of side positioning beads fall back in the blind hole 17 like this, thereby makes also release of side.So just reached the purpose of unblanking.
Because the blind hole 17 that the utility model must guarantee 5 side hoodles 8 aligned through holes 11 simultaneously makes in the parallel withdrawal lock gall 5 of side positioning bead 10 and can unblank, and has strengthened the anti-theft feature of lock thus.
The number of described side hoodle 8 and end face hoodle can also be done appropriate change, and to change its permutation and combination number, the permutation and combination number is many more, and the mutual opening rate of key is just low more, and anti-theft feature is also strong more.
