Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the vertical view of Fig. 1.

Among the figure, 1, lock pin, 2, handle, 3, door, 4, lock body, 5, lock core, 6, fixed body, 7, dead bolt.

The specific embodiment

Among Fig. 1, the cylindrical of columnar structured lock body 4 top and door 3 welding, the tube end, be provided with eccentric through-hole.Fluting place in lock core 5 upper ends loads onto the handle 2 of T shape structure with lock pin 1.The lock core 5 of at the bottom of 4 of lock bodies, packing in the eccentric through-hole, dead bolt 7 is inserted in lock core 5 back welding, notices during dead bolt 7 welding that direction slots parallel with lock core 5.Dead bolt 7 is corresponding with the aperture of fixed body 6, can play position-limiting action.Handle 2 can be along lock pin 1 upset of lock core 5 flutings.

Among Fig. 2,1 is lock pin, and 2 is handle, and 3 is door, and 4 is lock body, and 5 is lock core.

The operating principle of the utility model: hand-held handle 2, rotation can core 5 with lock and dead bolt 7 rotate tour together, simultaneously, handle 2 can turn over turnback along the lock pins 1 in the lock core 5.When handle 2 upset lay in the groove of lock body 4, dead bolt 7 had just been fixed a direction, simultaneously dead bolt 7 also in fixed body 6 endoporus, at this moment, not only limit to but also spacing.When mentioning handle 2, forward 90 again to when spending, dead bolt 7 leaves fixed body 6 eyelets, does not have position-limiting action, can mention door 3, door 3 can be opened, at this moment, handle 2 can not lie in the groove of lock body 4, this just expression door 3 do not shut.Have only when handle 2 upset lies in the groove of lock body 4, door 3 be only shut also spacing.
