Description

Special-shaped pearl idle-run lock head
Technical field:
The utility model relates to a kind of lock, and in particular, it relates to a kind of tapered end.
Background technology:
Existing ball lock head majority by housing, be enclosed within that rotary lock core and pellet shot from a slingshot etc. thereof constitute in the housing, housing and lock core corresponding vertically have several pellet shot from a slingshot holes, a spring is put in each pellet shot from a slingshot hole, a housing pellet shot from a slingshot, a lock core marble.During locking, housing pellet shot from a slingshot insertion lock core card in various degree stops lock core to rotate between housing and lock core.The lock of this structure can be twisted off when lock core is inserted the pellet shot from a slingshot that stops lock core to rotate when keyhole is done powerful reversing by special instrument, makes this lock lose anti-theft feature.
Summary of the invention:
The purpose of this utility model provides a kind of special-shaped pearl idle-run lock head that can overcome existing defective in the prior art, its lock core is in idling conditions when locking, insert unlocking tool or other objects, can rotational lock core, but can not unblank, this lock can effectively be defendd improper unblanking such as brute force is unblanked, technology unlocking, and theftproof is very good.
The utility model is achieved by the following technical solution: it is by housing, outer lock core, internal cylinder, special-shaped pearl constitutes, internal cylinder is enclosed within the outer lock core, outer lock core is the main body of unblanking, have several special-shaped pearl grooves in internal cylinder, each special-shaped pearl groove is put into a special-shaped pearl and a spring, each special-shaped pearl is provided with on its outside of projection and has notch, be in internal cylinder corresponding to notch and have secondary bullet groove, built-in secondary pellet shot from a slingshot has the clutch cotter way at outer lock core corresponding to secondary bullet groove, built-in on-of pin, in housing, have lock slots corresponding to clutch cotter way place, have the pellet shot from a slingshot hole in the lock slots, spring is equipped with in the inside, and pellet shot from a slingshot.
The utility model is in idling conditions when locking, when foreign matter or unlocking tool insert rotational lock core arbitrarily, but can not unblank, so this lock can effectively be defendd improper unblanking such as brute force is unblanked, technology unlocking, theftproof is very high.
Description of drawings:
Fig. 1 is the cross section view of the utility model embodiment blocking;
Fig. 2 is the cross section view of the utility model embodiment unlocking condition;
Fig. 3 is the A-A sectional view of Fig. 1.
The specific embodiment:
Fig. 1-the 3rd, embodiment of the present utility model is made of housing 1, outer lock core 2, internal cylinder 3, special-shaped pearl 5 etc.Described internal cylinder 3 is enclosed within the outer lock core 2, outer lock core 2 is the main body of unblanking, have several special-shaped pearl grooves 4 in internal cylinder 3, each special-shaped pearl groove 4 is put into a special-shaped pearl 5 and a spring 7, each special-shaped pearl 5 is provided with projection 17, have notch 8 on the outside of special-shaped pearl 5, corresponding to notch 8 places, have secondary bullet groove 9 in internal cylinder 3, built-in secondary pellet shot from a slingshot 10, have clutch cotter way 11 at outer lock core 2 corresponding to secondary bullet groove 9 places, built-in on-of pin 12 has lock slots 13 corresponding to clutch cotter way 11 places in housing 1, have one in the lock slots 13 to several pellet shot from a slingshot holes 14, spring 16 and pellet shot from a slingshot 15 are equipped with in the inside.
As shown in Figure 2, when unblanking, key 20 inserts, under the promotion of tartar 21, special-shaped pearl 5 is moved, the notch 8 of all special-shaped pearls 5 is all to chief and vice pellet shot from a slingshot 10, under the effect of return spring 16, secondary pellet shot from a slingshot 10, on-of pin 12, return pellet shot from a slingshot 15 move together inwards, and the inner 19 of secondary pellet shot from a slingshot 10 falls into notch 8, and internal cylinder 3 is inserted in the inner of on-of pin 12, be stuck between internal cylinder 3 and the outer lock core 2, internal cylinder 3 and outer lock core 2 are connected as a single entity, and lock slots 13 is then withdrawed from its outer end, and twisting key 20 just can be unblanked.During locking, extract key 20, special-shaped pearl 5 is moved under the effect of spring 7, its notch 8 departs from secondary pellet shot from a slingshot 10, the top is compeled secondary pellet shot from a slingshot 10 and is outwards moved, and secondary pellet shot from a slingshot 10 promotes on-of pin 12, makes the inner of on-of pin 12 withdraw from internal cylinder 3, internal cylinder 3 is in idling conditions, lock slots 13 is inserted in the outer end of on-of pin 12 simultaneously, is stuck between housing 1 and the outer lock core 2, and outer lock core 2 can not be rotated, form lock-out state, at this moment, internal cylinder 3 is in idling conditions, when foreign matter or unlocking tool insertion, can rotate internal cylinder 3, but can not unblank.
