The specific embodiment

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is done further and to be elaborated:

Embodiment

Such as Fig. 1 to shown in Figure 6: the insertion-core lock structure that the utility model provides, comprise loam cake 1, lock housing 2, interior Paula seat 3, handle assembly and commutation screw 7, be equipped with the installing hole 8 of commutation screw 7 in loam cake 1 and lock housing 2; Described handle assembly comprises that outer handle dial disc 4, interior handle dial disc 5 and handle even coil 6, outer handle dial disc 4 all even coils 6 mutually assemblings with handle with interior handle dial disc 5, its China and foreign countries' handle dial disc 4 is fixed in the fixing hole of loam cake 1 to fix with lock body by establishing thereon boss B4.3, interior handle dial disc 5 is fixed in the fixing hole on the lock housing 2 to fix with lock body by establishing thereon boss B5.2; Outer handle dial disc 4 and interior handle dial disc 5 all connect the pin 6.1 coil on 6 and drive handles and connect and coil 6 rotations by being located at handle.

Operating principle of the present utility model is as follows:

By Fig. 3 and shown in Figure 4: before inside and outside handle commutation, commutation screw 7 has arrived outer handle side with interior Paula seat 3 tops; When can operating outer handle dial disc 4 by the square hole 4.1 on the outer handle dial disc 4, outer handle (not shown) turns clockwise; When the boss A4.2 of outer handle dial disc is pinned by the boss 3.1 of interior Paula seat, outer handle dial disc 4 can not rotate again, is in the state of being lockable, but this moment since the boss A5.1 of interior handle dial disc pinned by the boss 3.1 of interior Paula seat, can clockwise rotate, be in the state of not being lockable.

By Fig. 5 and shown in Figure 6: when inside and outside the needs during handle commutation, with commutation screw 7 with interior Paula seat 3 tops to interior handle side; Can clockwise rotate because the boss A4.2 of outer handle dial disc is not pinned by the boss 3.1 of interior Paula seat this moment, is in the state of not being lockable; But the boss A5.1 of interior handle dial disc can be pinned by the boss 3.1 of interior Paula seat when rotating, and consequently interior handle can not rotate again, is in the state of being lockable.

In sum as seen, the insertion-core lock structure that the utility model provides, by the commutation screw is set, use the commutation screw that interior Paula seat is pushed up outer handle side or interior handle side, can realize that outer handle dial disc and interior handle dial disc are lockable the mutual conversion of state, thereby realize inside and outside handle commutation, have simple in structure, easy to operate, use the advantages such as flexible, have practical value.

Be necessary at last to be pointed out that at this; above-mentioned explanation only is used for the technical solution of the utility model is described in further detail; can not be interpreted as the restriction to the utility model protection domain, some nonessential improvement and adjustment that those skilled in the art makes according to foregoing of the present utility model all belong to protection domain of the present utility model.
