[specific embodiment]
As shown in Figures 1 to 4, a kind of escape lock that is easy to commutation, include latch bolt assembly 1, side's tongue assembly 2, lock body shell 4, be arranged on the pull-fork assembly 5 in lock body shell 4, and the striking gear 11 of annexation is stirred in formation between pull-fork assembly 5 and square tongue assembly 2, described pull-fork assembly 5 includes dials tongue piece 6, upper shift fork 7, lower shift fork 8, set aside tongue piece 9 and be clipped in, lower shift fork (7, 8) the middle shift fork 10 between, the upper tongue piece 6 of dialling is connected on upper shift fork 7, setting aside tongue piece 9 is connected on lower shift fork 8, on, set aside tongue piece (6, 9) and all pull-fork assembly concentrics swing, described middle shift fork 10 forms and stirs annexation with striking gear 11, be inserted with handle square bar 12 in the square hole of pull-fork assembly 5, described handle square bar 12 comprises spacing square bar 120 and jack square bar 121, be provided with upper limit boss 1210 at jack square bar 121, the distance of the tail end that the positive stop end of described upper limit boss 1210 is nearest to this jack square bar 121 equals the part thickness of upper shift fork 7 and these jack square bar 121 contact surfaces, be provided with lower limit boss 1200 on this spacing square bar 120, the distance of the tail end that the positive stop end of described lower limit boss 1200 is nearest to this spacing square bar 120 equal lower shift fork 8 and middle shift fork 10 respectively with the part thickness summation of these spacing square bar 120 contact surfaces.
As shown in Figure 2, offer the upper draw-in groove 60 coordinated with the upper fixture block 70 of upper shift fork 7 on upper group of tongue piece 6, offer the lower bayonet slot 90 coordinated with lower fixture block 80 on lower shift fork 8 setting aside on tongue piece 9.
As shown in Figure 1, also be equipped with in lock body shell 4 and be convenient to lock the latch assembly 3 lifted, this latch assembly 3 is comprised of latch 30, latch spring 31, latch shift fork 32 and latch return unit 33.Also be respectively equipped with when easy to use the world gib head slide plate 13 that carries out stroke adjustment in lock body shell 4 both sides, each world gib head slide plate 13 is provided with regulates chute 130.
When rotation is positioned at the handle (not shown) on spacing square bar 120, the lower shift fork 8 that spacing square bar 120 can drive on it simultaneously and then rotates together with middle shift fork 10, so just can be when the state of locking a door that square tongue secondary or secondary stretch out, by the reversed column on middle shift fork 10, make striking gear 11 produce action, square tongue on the side's of stirring tongue assembly 2 enters into that lock body shell 4 is interior to have opened the door, thereby realize that the handle rotated on spacing square bar 120 escapes when the state of locking a door that square tongue one-level or secondary stretch out: and rotate while being positioned at the handle (not shown) on jack square bar 121, the upper shift fork 7 that it only drives on it rotates, also just can not make by the reversed column on middle shift fork 10 striking gear 11 produce action, so stretch out while locking a door state at the square tongue one-level of square tongue assembly 2 or secondary, the handle rotated on jack square bar 121 can not be realized opening the door, that is to say that handle on jack square bar 121 can only stir latch bolt and open the door and can not open the door by the side's of drive tongue.So the utility model, when installing and using, the spacing square bar 120 of lower limit position boss 1200 is arranged in room, and jack square bar 121 is arranged on outside room, when escape, with regard to the handle on rotatable spacing square bar 120, fled from disaster field rapidly.According to L.H.flapped door or the needs of R.H.flapped door, as long as jack square bar 121 is injected until blocked by upper limit boss 1210 from square hole one end of pull-fork assembly 5, at this moment being loaded on inside and outside handle gets final product, saved and also will twist and get the operation that the screw on pull-fork assembly 5 commutates, so commutation of the present utility model is more convenient, the operation is simpler.
The above embodiment just, for preferred embodiment of the present utility model, not limits practical range of the present utility model with this, and the equivalence that all shapes according to the utility model, structure and principle are done changes, and all should be covered by protection domain of the present utility model.
