The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, Figure 11, Figure 12, Figure 13, Figure 14, Figure 15, Figure 16, Figure 16, Figure 18, Figure 19, Figure 20 and Figure 21, the two coaxial three slide system tapered ends of pearl of double flute of the present invention, by lock shell 1, see Fig. 1, front lock core 2, is shown in Fig. 3, rear lock core 3, is shown in Fig. 5, set bar 4 is shown in Fig. 8, four tapered ends that part forms, lock shell 1 comprises front and back lock core groove 12, interlock cotter way 13 and upper hoodle spring groove 14, interlock cotter way is positioned on front and back lock core groove and with front and back lock core groove and communicates, interlock cotter way 13 is for placing set bar, set bar is the set bar 4 of inverted L shape, upper hoodle spring groove 14 is positioned on interlock cotter way and with interlock cotter way and communicates, wherein, upper hoodle 5 is placed in hoodle spring groove 14, upper hoodle 5 tops are connected with upper spring 6, and upper hoodle 5 lower ends are pressed on the upper surface of set bar 4 by upper spring 6 interaction energies, front lock core 2 and rear lock core 3 are one in front and one in back placed in front and back lock core groove 12, front lock core comprises keyhole 23, be positioned at the bullet croze and the ball race that is positioned at keyhole both sides of the placement bullet bolt 10 on keyhole, play bolt 10 bottoms and be provided with two V-type rail heads side by side, ball race is placed with hoodle 7, hoodle axle 8 and return spring 9, hoodle 7 connects hoodle axle 8, hoodle axle 8 is provided with return spring 9, the upper surface that is shaped as of hoodle 7 has the V-type tooth 16 that tooth tip energy level that V groove 15 and lower inside surface are provided with reaches in keyhole to see Fig. 9, Figure 10 and Figure 11, at the ball race of every side, being placed with a plurality of its upper surfaces side by side has tooth tip energy level that V groove and lower inside surface are provided with to reach the hoodle of the V-type tooth in keyhole, the tooth tip of the V-type tooth 16 of the corresponding hoodle 7 of the described both sides that are positioned at keyhole 23 is to see Figure 12 over against arranging, the tooth tip setting that reaches respectively the V-type tooth 16 of the hoodle in keyhole from both sides ball race is that the tooth tip of a side is facing to the tooth tip of opposite side, the setting position of the V groove 15 of described hoodle upper surface is corresponding with the teeth groove of key 11, when original key is inserted, the tooth tip energy level that the teeth groove promotion hoodle lower inside surface of key is provided with reaches the V-type tooth 16 in keyhole and makes the V groove 15 of the hoodle upper surface of every side can form a linear V-type groove, thereby make two V-type rail heads 17 of bullet bolt 10 bottoms that are located thereon can fall into respectively corresponding linear V-type groove, play bolt 10 and see Figure 13 and Figure 14, hoodle axle 8, is shown in Figure 12, return spring 9, is shown in Figure 12.Also has key 11, see Figure 15, hoodle 7, between hoodle axle 8 and return spring 9 each elements, relation is shown in Figure 12, described rear lock core 3 its front ends are stirred fork 18, rear portion is provided with slot 19, the vertical latch 21 of the set bar 4 of inverted L shape can be inserted in the slot 19 that the rear portion of rear lock core is provided with, when set bar 4 rotates, can drive rear lock core to rotate, making to stir fork realization unblanks or shuts object, the transverse bar 20 of the set bar 4 of inverted L shape be held in place in the interlock cotter way 13 on the bullet bolt 10 of front lock core and with play bolt 10 upper surfaces and be abutted against, when playing when bolt moves up and down, can drive set bar to move up and down, when two the V-type rail heads side by side that are provided with when the bottom of bullet bolt fall into the surperficial formed two linear V-type groove of hoodle of the ball race that is arranged in keyhole both sides, the transverse bar of the set bar of inverted L shape moves into bullet croze from interlock cotter way and enters lock core groove 22 again, now when key band movable lock core rotates, the transverse bar of the set bar of inverted L shape can rotate together along with lock core, now the vertical latch of set bar drives rear lock core to rotate together, the fork of stirring of rear lock core rotates and realizes and unblank or shut object, lock outward appearance three-view diagram is shown in Figure 17, A-A sectional view is shown in Figure 19, B-B sectional view is shown in Figure 20, C-C sectional view is shown in Figure 21.Front lock core rear portion has lock core groove 22 and sees Figure 20, has had lock core groove, and the set bar of inverted L shape could move to cotter way and play in croze and fall into lock core groove 22 from interlock.
Operating principle of the present invention: when lock is in the state of lock, see Figure 19, at this moment, the V groove of hoodle is not on a line, so play bolt 10 by hoodle 7 jack-up, like this, any key enters keyhole, can rotate front lock core, set bar is in lock shell, rear lock core can not rotate, and namely idle running, reaches anti-theft function.
When original key enters, see Figure 20, Figure 21, at this moment, after hoodle two row V grooves are pushed by original key all on a line, so, play two V-type rail heads 17 of bolt 10 bottoms, just enter in the linear V-type groove that the V groove of hoodle lines up in line, upper hoodle 5 is under upper spring 6 effects, pushing down set bar 4 makes to play bolt 10 and is depressed together, at this moment, set bar 4 has left the interlock cotter way 13 in lock shell, the bullet croze entering in front lock core falls into lock core groove 22 again, like this, set bar has just connected together front lock core and rear lock core, now, rotate key, front and back lock core has just rotated together, lock has just been left.The present invention is also provided with anti-drilling protection, because lock shell and front lock core 2 have anti-drilling screw protection to see Figure 22, number in the figure 24 is the anti-drilling screw of lock shell, and 25 is lock core drilling-preventing screw, so can tamper-proofly open.
