Fig. 3 is the utility model A-A cross-sectional view.
Detailed description of the invention:
As shown in Figure 1 to Figure 3, a kind of tapered end, described tapered end comprises lock body 1 and lock core 2, keyhole is provided with in the middle of lock core, the lock cylinder aperture 7 that described lock core and lock body are multiple in vertical direction, lock and back-moving spring 8 is provided with in lock cylinder aperture 7, often organize lock 8 to be made up of a flat pearl 6 and a sharp pearl 4, described lock core 2 lower horizontal direction is provided with multiple track hole of beads, track pearl 21 and back-moving spring 17 is provided with in the described track hole of bead, described track pearl side is provided with and promotes protruding 13, and this promotion projection extends in keyhole, bottom lock core, the below in multiple track hole of beads is provided with a banking pin 3, Compress Spring 22 is provided with between described banking pin and lock core bottom surface, lock slots 14 is provided with in the lower wall of a track pearl, correspondence is provided with lock hole in banking pin bottom surface, locking column 15 is provided with in lock hole, locking column corresponds to and is provided with locking blind hole 16 in the position of lock body 1 inwall, described locking column 15 upper end may slide in lock slots 14.The length ratio of flat pearl 6 and a sharp pearl 4 and the setting position of promotion protruding 13 are the lockset position of coupler of key, and this can convert according to the manufacture of lockset, and is equipped with suitable key.Described lock core rearward end is also connected with a plectrum by screw, and plectrum is for driving dead bolt.
Second group of lock in described lock cylinder aperture is engineering lock, flat pearl wherein and sharp pearl therebetween are provided with engineering ball 5, first group of described lock is sealing lock, and the sharp pearl extension of its front end touches the respective side inwall of keyhole, and sharp pearl forms the effect of a sealing at keyhole oral area.In lock core, be provided with engineering pearl accordingly fall into hole 51.Sealing lock is used for preventing dust and other impurities from entering in keyhole, ensures the fluency run.Engineering ball 5 installs key to engineering staff for being equipped with, and after installation terminates, adopts formal key that engineering pearl is put into engineering pearl fall into hole 51, engineering key is cancelled.
Be provided with a locating hole in described lock body, be provided with retainer spring 10 and a positioning bead 11 in locating hole, correspondence is provided with a Blind locating holes on lock core.Blind locating holes is used for for positioning bead 11 clamping location.
Described tapered end is provided with the lock cylinder aperture of six and the track hole of bead of four.
This lock head structure is the theft-prevention structure that 6 groups of hoodle posts coordinate 4 track pearls, can improve antitheft coefficient, improves key difficulty of reproduction.Hoodle of sealing up a door is fixed on below flat pearl, then connects pearl spring, then is fixed on flat pearl.In the connection of second group of spring column and flat pearl, add engineering steel ball, increase its hardness, other pearl posts are all formed by hoodle, flat pearl, pearl spring, flat pearl.Matching with position, key hole bottom hoodle could be movable.Because be have distance between pearl post and pearl post, the hole distance of positions of key, from could be movable with pearl post distance, will be not easy imitated key like this.Four track pearls have distance, shape, and being formed specificly has scope of activities, key event trace groove, and can not coincide can not be movable.
