Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is illustrated:

As shown in Figure 1, a kind of square tongue drive mechanism based on American Standard lock body, comprises lock body shell 1, generous tongue 2, square tongue shift fork 3; Generous tongue 2 is connected with square tongue shift fork 3, and generous tongue 2 and square tongue shift fork 3 are assemblied in the inside of lock body shell 1 jointly; Lock body shell 1 there is the square hole 11 that can go out for generous tonguing, lock body shell 1 also has circular hole 12, side's tongue shift fork 3 has on the first cylindrical end 31. side tongue shift fork 3 and has the second cylindrical end 32, it is inner that described first cylindrical end 31 is assemblied in circular hole 12, and square tongue shift fork 3 can rotate around the central axis of circular hole 12;

Generous tongue 2 there is the first groove 21, first groove 21 comprise the first end points 211, second end points 212, rib 213; Described side's tongue shift fork 3 also comprises first input end 33, second input 34, the 3rd input 35, four-input terminal 36; First input end 33 is square hole; Described generous tongue 2 comprises salient point 22, and lock body shell 1 comprises the second groove 13, second groove 13 and comprises the 3rd end points 131, the 4th end points 132;

As shown in Figure 2, under reset condition, generous tongue 2 is inner at lock body shell 1, and it is inner that described second cylindrical end 32 is assemblied in the first groove 21, now the second cylindrical end 32 of described side's tongue shift fork 3 is assemblied in the first end points 212 place of the first groove 21, the salient point 22 of described generous tongue 2 is at the second groove 13 low order end i.e. the 3rd end points 131 place, because the second input 34 and four-input terminal 36 stretch out structure for what can be struck, 3rd input 35 is gear structure, and above four inputs all can be connected with external component, and namely the rotation of square tongue shift fork can be realized by these four inputs, when first input end 33, second input 34, 3rd input 35, any one input of four-input terminal 36 receives the extraneous active force side of making tongue shift fork 3 when circular hole 21 dextrorotation, second cylindrical end 32 stirs the rib 213 of the first groove 21 of generous tongue 2, generous tongue 2 is subjected to displacement, when square tongue shift fork 3 turn clockwise 72 degree time the second cylindrical end 32 position at the second end points 211 place time, now salient point 22 has slid into high order end i.e. the 4th end points 132 place of the second groove 13, now generous tongue 2 has stretched out lock body shell 1 and has stopped being moved to the left the state reached shown in Fig. 3, owing to being subject to the spacing of lock body shell 1, so generous tongue 2 is now no longer moved to the left, the continuation clockwise movement of side's tongue shift fork 3 cannot stir generous tongue 2, contrary now square tongue shift fork 3 is rotated counterclockwise, will drive generous tongue 2 to the right indentation lock body shell 1 reach the state shown in Fig. 2.

To sum up, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
