Background technology
The mechanical door lock that uses at present all is that a tapered end and a lock core combine, and key operated by one.Because simple in structure, the interlocking capability of lockset itself is poor, is very easily pried open by master key, perhaps extraneous less destructive power can both open it, and the safety of lockset is relatively poor.For the safe deposit box that bank is used for taking care of valuables, its security requirement is higher, and existing mechanical lock commonly used can not satisfy the needs of its security performance, so it is good to develop a kind of interlocking performance, the double-end mechanical lock that security performance is high is particularly urgent.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of double-end mechanical lock is provided, this double-end mechanical lock interlocking performance is good, realizes that many people pin down management, has higher theftproof performance, and safety in utilization is reliable.
In order to realize above-mentioned technical purpose, the present invention realizes by following technical scheme:
Double-end mechanical lock of the present invention; Comprise box body, lid and dead bolt; Said lid to box body inside is provided with the secondary lockhole that main lockhole that master key passes and secondary key pass; Be provided with the long lock core that runs through main lockhole in the said main lockhole, the said secondary lockhole interior location of cap portion that places is provided with short lock core, is provided with in the said box body earlier and opens the interlock that secondary key just can be opened dead bolt behind the unlatching master key.
Further improvement as above-mentioned technology; In the said box body corresponding to the position of main lockhole range upon range of be provided with some main lock pieces; In the said box body corresponding to the position of secondary lockhole range upon range of be provided with some secondary locking plates; Said bottommost main lock piece is concordant with the secondary locking plate of bottommost bottom; Said interlock is the interlocking sheet that is stacked in bottom main lock piece and the secondary locking plate of bottom bottom, and an end of said interlocking sheet is movably connected in the position near the box body of main lock core, and the inlet of secondary key is blocked in the other end; Be penetrated with the shifting fork bar with short lock pin coaxial and interlock in the said secondary lockhole, the bottom of said shifting fork bar is provided with mechanical lock when closing, and the top supports dead bolt, make dead bolt break away from the shift fork of withdrawing and then unblanking after the top is supported after turning to.
In invention, in order to improve the reseting performance of interlocking sheet, said 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 present invention, said main lock piece is 5, and said secondary locking plate is 6, and close spoon amount reaches the combination more than 200,000, improves the security performance of lockset greatly.
Compared with prior art, the invention has the beneficial effects as follows:
Double-end mechanical lock of the present invention could insert secondary lockhole with secondary key through opening earlier master key, and the revolute pair key could unlock deadbolt then, and then reaches 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 present invention explains with the right side door lock that is installed in safe deposit box:
Like Fig. 1, shown in Figure 2; Double-end mechanical lock of the present invention comprises box body 2, lid 3 and dead bolt 1, and said lid 3 to box body 2 inside are provided with the main lockhole 5 that supplies master key 4 to pass; With the secondary lockhole 7 that supplies secondary key 6 to pass; Be provided with the long lock core 8 that runs through main lockhole 5 in the said main lockhole 5, place secondary lockhole 7 interior locations to be provided with short lock core 9, be provided with in the said 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.
Like Fig. 3, shown in Figure 5; In the said box body 2 corresponding to the position of main lockhole 5 range upon range of be provided with five main lock pieces 10; In the said box body 2 corresponding to the position of secondary lockhole 7 range upon range of be provided with six secondary locking plates 11, and place bottommost main lock piece 10 concordant, owing to the setting of multilayer main lock piece 10 and secondary locking plate 11 with the secondary locking plate of bottommost 11 bottoms; Make the close spoon amount of mechanical lock reach the combination more than 200,000, improve the security performance of lockset greatly.
Specifically; Like Fig. 3, shown in Figure 4; Said 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, is penetrated with the shifting fork bar 13 of and interlock coaxial with short lock core 7 in the said secondary lockhole 7, and the bottom of said shifting fork bar 13 is provided with mechanical lock when closing, and the top supports dead bolt, make dead bolt break away from the shift fork 131 of withdrawing and then unblanking after the top is supported after turning to.
In invention, in order to improve the reseting performance of interlocking sheet 12, like Fig. 6, shown in Figure 7, said 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 just the course of work of double-end mechanical lock of the present invention specify:
⑴ when open door lock,, at first get in the long lock core 8 with master key 4 like Fig. 5, shown in Figure 6; 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, this moment, ⑵ inserted secondary key 6; Revolute pair key 6 drives short lock core 9 and shifting fork bar 13 clockwise rotates; No longer push up after shifting fork bar 13 rotates and prop up dead bolt 1, this moment, dead bolt 1 withdrawal realized the purpose of opening the door;
⑵ 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, and this moment, shift fork 131 tops of shifting fork bar 13 propped up dead bolt 1; Realize the locking function of dead bolt 1, door lock is closed.
