Lock body 3 has lockhole 31, have the spool 32 for closure or openness door lock in lockhole 31, lock core 32 exposes lockhole 31, is connected with the connection part (1b) of handle 1 by coupling arrangement 4, realizes interlock.

Linkage 4 comprises connector 41 and installed part 42.

The present embodiment is preferred, and STATEMENT OF FEDERALLY SPONSORED 41 comprises two pull bar 411a and two driver plate 412a.The two ends of the side of pull bar 411a are respectively equipped with two protruding 4111a, are provided with certain gap for coordinating driving coupling between two protruding 4111a; Two driver plate 412a are separately fixed at the connection part 1b of handle 1 and expose on the spool 32 of lock body 3, driver plate 412a is provided with group bar 4121a for driving coupling, dial bar 4121a for two all to stretch out settings along the radial direction of the center of rotation of driver plate 412a, and two to dial bar 4121a edges symmetrical along the center of rotation of driver plate 412a.

When pull bar 411a and driver plate 412a assembles, two pull bar 411a are separately positioned on the both sides of driver plate 412a, the bar 4121a that dials of driver plate 412a is fastened on the gap of two protruding 4111a of pull bar 411a, the gap of dialling between the length of bar 4121a and two protruding 4111a needs the angle opening and closing the rotation of door lock needs to arrange accordingly according to the lock core 32 specifically locked, and ensures that lock core 32 group bar 4121a in rotary course can not depart from the gap between two protruding 4111a.

In other embodiments, STATEMENT OF FEDERALLY SPONSORED 41 comprises an a pull bar 411a and two driver plate 412a, and the basis of above-described embodiment decreases the pull bar 411a of side, and STATEMENT OF FEDERALLY SPONSORED 41 can realize the interlock of handle 1 and lock core 32 equally, and stability is relatively poor.

Installed part 42 comprises base plate 421 and upper cover 422.

Base plate 421, described base plate 421 is fixed on described lock body 3, base plate 421 is divided into two parts in the present embodiment, a middle formation gap, for dodging lock body structure, and can be cost-saving, in embodiment in fact, base plate 421 can be established as a whole, on that face of lock body 3, be provided with groove or cavity;

Upper cover 422, upper cover 422 comprises top board 4221 and along the vertically extending side plate 4222 in top board 4221 edge, described side plate 4222 is provided with for hard-wired installation portion 4223, and upper cover 422 is fixed on lock body 3, also can directly be fixed on base plate 421 in other embodiments.

Base plate 421 and upper cover 422 enclose the cavity for accommodating STATEMENT OF FEDERALLY SPONSORED 41 two pull bar 411a, pull bar 411a can along linear slide in both handle 1 installation portion 1b and spool 32 rectilinear direction in cavity, and all being limited by cavity on other directions, namely cavity defines a guide groove.Base plate 421 and upper cover 422 are equipped with the connection part 1b dodging handle 1 and expose the through hole of spool 32 of lock body 3.

During utility model works, swing handle 1, stir pull bar 411a rectilinear motion in the cavity of installed part 42 by driver plate 412a fixed thereon, the other end of pull bar is with movable lock core 32 to rotate by the driver plate 412a be fixed on lock core 32, achieves the interlock of handle 1 and lock core 32.

The utility model achieves the interlock of handle 1 and lock core 32 by increasing linkage 4, the specification that can design at existing lock body is directly reequiped, handling position is moved down, reserve the intelligent input region of electronic lock, do not need in order to production part electronic lock, and additional designs manufactures corresponding lock body, save a large amount of costs.

Embodiment two:

Please refer to Fig. 4, the present embodiment and embodiment one difference are, STATEMENT OF FEDERALLY SPONSORED 41 comprises two tooth bar 411b and two gear 412b, two gear 412b are separately fixed at the connection part 1b of handle 1 and expose on the spool 32 of lock body 3, two tooth bar 411b are placed in the cavity of installed part 42, connect with two gear 412b engaged transmission.

What the present embodiment replaced embodiment a kind of pull bar 411a and driver plate 412a by the engaged transmission of tooth bar 411b and gear 412b stirs transmission, achieves the interlock of handle 1 and lock core 32 .

In other embodiments, STATEMENT OF FEDERALLY SPONSORED 41 comprises an a tooth bar 411b and two gear 412b, and can realize the interlock of handle 1 and lock core 32 equally, stability is relatively not good enough.
