The specific embodiment

As shown in Figure 1, anti-theft lock end described in the utility model comprises external lock head capsule 1 and the lock core 6 that is installed in the external lock head capsule 1.As shown in Figure 4, external lock head capsule 1 is cylindric, the one end opening, openend fixed installation outer tapered end cover 8 as shown in Figure 8, have lock gall hole and lock hole 8C on the outer tapered end cover 8, the other end of external lock head capsule has side plate 1A, has tapered end hole 1B and locking column hole 1C on the side plate 1A; Cooperate the inner lock head 2 that is equipped with as shown in Figure 5 in the tapered end shell 1 outside, inner lock head 2 is cylindric, the one end opening, openend fixed installation internal lock skull 7 as shown in Figure 9 has the interior lock hole 7A corresponding with lock hole 8C on the internal lock skull 7, the other end has side cover, have tapered end axle 2A on the side cover, have inner lock head lock hole 2B on the side cover around the tapered end axle 2A, tapered end axle 2A is inserted among the 1B of tapered end hole, and inner lock head lock hole 2B is corresponding with locking column hole 1C; In the cylindric inner chamber of inner lock head 2, be equipped with as Fig. 2, lock core 6 shown in Figure 7, lock core 6 is cylindric, its two ends have locking disk chamber 6A, the center has the lock gall chamber 6B coaxial with it, be equipped with among the 6B of lock gall chamber as Fig. 3, lock gall 5 shown in Figure 10, lock gall 5 is the tubulose of hollow, and tube wall upper edge circumference has a plurality of keyhole 5A that unblank; Have a plurality of keyhole 6C that radially are provided with on the lock core body between the two locking disk chamber 6A, this keyhole 6C evenly distributes along the circumference of lock core 6, unlock key 11 as shown in figure 11 is installed among the keyhole 6C, its upper end is connected to inner lock head 2 by spring, the lower end is inserted among the keyhole 5A that unblanks, the side of unlock key 11 has the keyway 12 of unblanking, and has through hole and be communicated with keyhole 6C and locking disk chamber 6A on the lock core body between keyhole 6C and the locking disk chamber 6A; Locking disk 4 as shown in Figure 6 is installed among the 6A of locking disk chamber, the both sides of locking disk 4 have locking column 9 and following locking column 10 respectively, last locking column 9 is inserted in the through hole between keyhole 6C and the locking disk chamber 6A, in being inserted into respectively, following locking column 10 among lock hole 7A and the inner lock head lock hole 2B, between the side cover of locking disk 4 and internal lock skull 7 and internal lock skull 7, return spring 4A is installed.

When this tapered end is in the lock state, the following locking column 10 in locking disk 4 outsides is inserted into respectively among interior lock hole 7A and the inner lock head lock hole 2B, also be inserted among lock hole 8C and locking column hole 1 C simultaneously, with inner lock head 2 lockings it can not be rotated relatively external lock head capsule 1, reach the purpose of locking.When unblanking, insert in the lock galls 5 with key as shown in figure 12 14, it is corresponding with unlock key 11 to have the keyhole 13 of unblanking on the key 14, if whole keyholes 13 of unblanking is corresponding one by one correct with unlock key 11, then the keyway 12 of unblanking on the unlock key 11 is understood automatic in-positions, this moment, locking disk 4 moved to the centre under the effect of return spring 4A, last locking column 9 all moves in each self-corresponding keyway 12 of unblanking, following locking column 10 natures shift out from lock hole 8C and locking column hole 1C, and external lock head capsule 1 is separated with inner lock head 2.This moment key 14, inner lock head 2 is along with rotation, tapered end is opened.

Otherwise, if insert false key, as long as the keyhole 13 of unblanking on the key has a malposition, can not be corresponding with all unlock key 11, as long as there is the keyway 12 of unblanking not in place, locking disk 4 just can not move, and following locking column 10 will firmly lock external lock head capsule 1 and inner lock head 2, make it and to rotate, can not open.
