The controlling organization of oblique tongue 27 in Fig. 1 comprises oblique tongue dial sleeve 18, oblique tongue dial sleeve post 19, torsion spring 26, oblique tongue post 27, oblique tongue junction plate 28 etc., all belongs to known technology, and this paper no longer describes in detail.Master latch adopts steel plate and four cylinder tongue 31 direct riveteds, and is sturdy and durable, has the pick-proof effect, and the quantity of cylinder tongue 31 should not be limited to 4; Supporting plate 11 and the master latch riveted made with steel plate are fixed with slide plate stroke guide pillar 1 (see figure 5) in the central authorities of supporting plate 11, and guide pillar 1 places in upper sliding valve inclined hole 20 and the downslide bolt inclined hole 21 simultaneously, and guide pillar 1 outside is with slide plate guide pin bushing 2; Also have an in-line slide opening 22 on supporting plate 11, cover is inserted with a supporting plate reference column 13 on the base plate that is fixed on lock box 6 in slide opening 22, make supporting plate 11 can only do transverse movement, and movement travel only limits to the length of slide opening 22.In conjunction with shown in Figure 6, have 3 grooves 23 in the upper end of supporting plate 11 to realize the third gear open function of master latch, cross key core-inset type tapered end 3 is arranged on groove 23 tops; Have 4 narrower grooves 38 in the lower end of supporting plate 11, make that the claw 39 on the portable plate 14 can snap in any groove 38 to realize the third gear unlatching positioning function of master latch.Upper and lower sliding bolt 34,24 is in lock box between the overlapping base plate that places supporting plate 11 and lock box 6, as shown in Figure 5.Last locking bolt stretches out along the lock box top, and following locking bolt stretches out along the lock box below.
As Fig. 1, shown in Figure 3, cross key inserting-core lock 3 is fixedly mounted on the lock box 6 by door shape bolt support 7 and long spiro nail 8, inserting-core lock 3 protrudes from the both sides of lock box 6, can both open in indoor and outdoor, and in needs, withdraw from long spiro nail 8 and just can change tapered end easily, and needn't change whole lock box.In like manner, the cross key inserting-core lock is changed into a word key inserting-core lock and also can realize the utility model.In addition, the structure of cross key inserting-core lock as shown in Figure 4, this tapered end is separate case application utility model patent, no longer describes in detail.
The structure of portable plate 14 is described in conjunction with Fig. 1,6 as shown in Figure 7, and it is provided with two vertical slide openings 40,41, supporting plate reference column 13 is housed in the slide opening 40, be with portable plate reference column 9 in the slide opening 41, a side of portable plate 14 also is provided with return spring 17, and an end of portable plate 14 is bent into one
Shape crimping cover is inserted in supporting plate 11 lower ends, and claw 39 snaps in the groove 38 of supporting plate 11; Be designed to milder pointed a at portable plate and tapered end shifting block 35 touching positions, make portable plate under the effect of tapered end shifting block 35, can move up and down.
The structure of upper sliding valve 34, downslide bolt 24 such as Fig. 8 and shown in Figure 9, both shapes are roughly the same, and upper sliding valve has bar shaped slide opening 42,43, and inclined hole 20 left ends are downward, and the downslide bolt has bar shaped slide opening 44,45, and inclined hole 21 left ends are upwards.Upper and lower sliding bolt is overlapping placement (as shown in Figure 3) in lock box, the bar shaped slide opening 42 of upper sliding valve and the bar shaped slide opening 44 of downslide bolt are with slide plate guide pillar 29 jointly, the bar shaped slide opening 43 of upper sliding valve and the bar shaped slide opening 45 of downslide bolt are with slide plate guide pillar 29 ' jointly, the inclined hole 20 of upper sliding valve and the inclined hole 21 of downslide bolt are with slide plate stroke guide pillar 1 jointly, and the length of aforementioned all slide openings, inclined hole should guarantee that upper and lower sliding bolt stretches out effectively and shrinks.
During use, key is inserted in the lock core 37 rotary locking cylinder 37, drive tapered end shifting block 35 and rotate, under the effect of tapered end shifting block projection, elder generation is with the pointed a place jack-up of portable plate 14, portable plate 14 integral body are moved down, cause claw 39 to break away from the groove 38 of supporting plate 11, the restriction of supporting plate 11 at this moment is disengaged; Tapered end shifting block 35 continues rotation, a sidewall of groove 23 of stirring supporting plate 11 is traversing, make supporting plate 11 and to drive cylinder tongue 31 traversing, when tapered end shifting block 35 rotates a circle, portable plate 14 has broken away from the control of tapered end shifting block, and under the active force of return spring 17, the claw 39 of portable plate 14 snaps in again in the next groove 38 of supporting plate 11, supporting plate plate 11,34,24 lockings of slide down bolt can not be stretched out and retraction it under external force.Lock core whenever rotates a circle, and realizes that a grade of master latch is opened or closed, and present embodiment is a third gear, and then lock core rotates three circles continuously, can realize that then third gear opens or close.
Because slide plate stroke guide pillar 1 is fixedly mounted on the supporting plate 11, make slide plate stroke guide pillar 1 when supporting plate 11 is done motion, also reciprocating, and guide pillar 1 is contained in the inclined hole 20,21 of slide down bolt, two inclined holes convert the transverse movement of guide pillar 1 to the vertical motion of upper and lower sliding bolt, in guide pillar 1 motion, upper and lower sliding bolt is also simultaneously reciprocating like this, reaches upper and lower unlatching, locking purpose.
