Further improvement as above-mentioned technology, in the described box body corresponding to the position of main lockhole stacked be provided with some main lock pieces, in the described box body corresponding to the position of secondary lockhole stacked be provided with some secondary locking plates, described bottommost main lock piece is concordant with the secondary locking plate of bottommost bottom, described interlock is the interlocking sheet that is stacked in bottom main lock piece and the secondary locking plate of bottom bottom, one end of described interlocking sheet is movably connected in the position near the box body of main lock core, the inlet of secondary key is blocked in the other end, be penetrated with the shifting fork bar of and interlock coaxial in the described secondary lockhole, the bottom of described shifting fork bar is provided with mechanical lock contact dead bolt when closing with auxiliary lock core, make dead bolt break away from the shift fork of withdrawing and then unblanking after the contact after turning to.

In utility model, in order to improve the reseting performance of interlocking sheet, described interlocking sheet is provided with a groove, is used for back-moving spring one end that the interlocking sheet resets and is embedded in groove, and the other end is conflicted in the interior sidewall surface of box body.

In the utility model, described main lock piece is 5, and described secondary locking plate is 6, and the secret key amount reaches the combination more than 200,000, improves the security performance of lockset greatly.

Compared with prior art, the beneficial effects of the utility model are:

The utility model double-end mechanical lock could insert secondary lockhole with secondary key by opening master key earlier, the revolute pair key could unlock deadbolt then, and then reach the purpose of opening door lock, make desire need open that door lock must be opened master key in order and secondary key just can be opened door, door lock interlocking performance is good, has realized that many people pin down management, effectively improve the door lock theftproof performance, safe and reliable, guarantee safety and theftproof performance that safe deposit box is higher.

The specific embodiment

The utility model is illustrated with the right side door lock that is installed in safe deposit box:

As shown in Figure 1 and Figure 2, double-end mechanical lock described in the utility model, comprise box body 2, lid 3 and dead bolt 1, described lid 3 to box body 2 inside are provided with the main lockhole 5 that passes for master key 4, with the secondary lockhole 7 that passes for secondary key 6, be provided with the long lock core 8 that runs through main lockhole 5 in the described main lockhole 5, place secondary lockhole 7 interior locations to be provided with short lock core 9, be provided with in the described box body 2 and open the interlock that the master key 4 back secondary keys 6 of unlatching just can be opened dead bolt earlier corresponding to lid 3 parts.

As Fig. 3, shown in Figure 5, in the described box body 2 corresponding to the position of main lockhole 5 stacked be provided with five main lock pieces 10, in the described box body 2 corresponding to the position of secondary lockhole 7 stacked be provided with six secondary locking plates 11, and place bottommost main lock piece 10 concordant with the secondary locking plate of bottommost 11 bottoms, because the setting of multilayer main lock piece 10 and secondary locking plate 11, make the secret key amount of mechanical lock reach the combination more than 200,000, improve the security performance of lockset greatly.

Specifically, as shown in Figure 3, Figure 4, described interlock is the interlocking sheet 12 that is stacked in bottom main lock piece 10 and the secondary locking plate of the bottom 11 bottoms, one end of this interlocking sheet 12 is movably connected in the position near the box body 2 of main lock core 5, the inlet of secondary key 6 is blocked in the other end, be penetrated with the shifting fork bar 13 of and interlock coaxial in the described secondary lockhole 7, the bottom of described shifting fork bar 13 is provided with mechanical lock when closing contact dead bolt, the shift fork 131 that makes after turning to dead bolt break away from withdrawal after the contact and then unblank with auxiliary lock core 7.

In utility model, in order to improve the reseting performance of interlocking sheet 12, as Fig. 6, shown in Figure 7, described interlocking sheet 12 is provided with a groove 121, is used for back-moving spring 14 1 ends that the interlocking sheet resets and is embedded in groove 121, and the other end is conflicted in the interior sidewall surface of box body 2.Below described in detail with regard to the course of work of the utility model double-end mechanical lock:

When (1) opening door lock, as Fig. 5, shown in Figure 6, at first enter in the long lock core 8 with master key 4, rotate master key 4 its driving interlocking sheet 12 pins are clockwise rotated around pin joint O, thereby the arrival end that makes interlocking sheet 12 get lodged in secondary key 6 leaves, (2) insert secondary key 6 at this moment, revolute pair key 6 drives short lock core 9 and shifting fork bar 13 clockwise rotates, after shifting fork bar 13 rotates no longer contact live dead bolt 1, this moment, dead bolt 1 withdrawal realized the purpose of opening the door;

(2) during spring lock, be rotated counterclockwise master key 4 and extract master key 4, be rotated counterclockwise secondary key 6 and extract secondary key 6, interlocking this moment sheet 12 rotates back to reposition counterclockwise under the effect of back-moving spring 14, this moment, shift fork 131 contacts of shifting fork bar 13 were lived dead bolt 1, realize the locking function of dead bolt 1, door lock is closed.
