The specific embodiment

Embodiment 1

See Fig. 1, Fig. 2; Automobile steering lock comprises lock body 10; Lock body 10 be provided with an outward extending baffle plate 11, with the depressed part 14 that bearing circle outer shroud 1 coincide, be provided with cooresponding hinged-

support

4,9 at the two ends of depressed part 14 left sides (top of bearing circle outer shroud 1), lock body 10 and baffle plate 11 fixing riveted joints; In the said hinged-

support

4,9, fix an anchor shaft 3 on the hinged-support 4, be fixed with tapered end 8 on another hinged-support 9; One free gear 6 is actively set on the other end of anchor shaft 3 and circumferentially spacing, is provided with free gear pull back spring 5 between free gear 6 and anchor shaft 3 axial, and the outer face of free gear 6 is provided with v-depression 16; In two hinged-supports 4, be provided with a turning set 2 between 9 and be enclosed within on anchor shaft 3 and the free gear 6; One end of turning set 2 be fixed with one with anchor shaft 3 on the fixed gear wheel 7 that cooperates of free gear 6 axial tooths; The end face of free gear 6 and fixed gear wheel 7 is provided with ratchet and matches; The one side of ratchet is the inclined-plane; Another side can only allow one of them gear with respect to another gear unidirectional rotation after two

gears

6,7 engagements for facing directly, the connecting portion 201 of turning set 2 be provided with coincide with bearing circle outer shroud 1 and with involutory two lock bridges 12 and the block 13 that is used to block horn punch dish on the bearing circle of the depressed part 14 on the lock body; Lock core in the tapered end 8 is provided with prominent 15 of V-arrangement at tail end and cooperates with v-depression 16 on the free gear 6.

The principle of work of the utility model:

During locking: see Fig. 3, go into key, rotational lock core 90 degree from the lock core skewer; Prominent 15 of lock core tail end V-arrangement axially pushed free gear 6 open through the inclined-plane makes it separate with fixed gear wheel 7, and at this moment, lock bridge 12 can be free movable with turning set 2; Be anchored to lock bridge 12 on the bearing circle then and dead, and baffle plate 13 blocked on the horn punch dish at bearing circle middle part with lock body 10 involutory outer shrouds 1 folders with bearing circle, revolving plug make prominent 15 of lock core tail end V-arrangement be positioned at free gear 6 on v-depression 16 position of matching; Can extract key; Free gear pull back spring 5 makes free gear 6 and fixed gear wheel 7 be in the constant-mesh state, and is as shown in Figure 4, and this moment, lock bridge 12 can only be with the outer shroud 1 of turning set 2 unidirectional rotation until the fastened orientation dish; Accomplish locking, as shown in Figure 1.

During unlatching: go into key from the lock core skewer; Rotational lock core 90 degree, prominent 15 of lock core tail end V-arrangement pushed free gear 6 open through the inclined-plane makes it separate with fixed gear wheel 7, at this moment; Lock bridge 12 can be free movable with turning set 2; Lock bridge 12 relies on the outer shroud 1 of the automatic opposite spin release direction of its gravity dish, removes lock promptly to accomplish and unblanks, and is as shown in Figure 2.
