Embodiment 1

[0044] figure 1 A locking device with multiple locks and two openings is exemplified, including an input gear 40 , an output gear 50 , a first clutch group 100 , a second clutch group 200 and a lock body driving group 300 . The input gear 40 is connected to the input shaft 41 . The output gear 50 is connected to an output shaft 51 . The input shaft 41 is used for connecting the handle. The output shaft 51 is used to connect the door bolt.

[0045] The lock body driving group 300 includes N clutch lock body driving mechanisms 3 . The clutch lock body driving mechanism 3 includes a lock body 31 and N−1 driving parts 32 . That is, the lock body driving group 300 includes N lock bodies 31 . Each lock body 31 is respectively connected with N−1 driving parts 32 . That is, there are N×(N−1) driving sections 32 in total.

[0046] The first clutch group 100 includes N×(N−1) / 2 first clutch gears 1 connected to the driving portion 32 . The second clutch group 200 includes N×(N−1)...

Embodiment 2

[0062] This embodiment is a locking device with multiple locks and two openings, more specifically, it is an implementation of the actual structure of the locking device with three locks and two openings in the first embodiment. Three locks and two openings can be simply called three openings and two openings. refer to Figure 6 , Figure 7 and Figure 8 , the three-in-two locking device includes an input shaft 41, an input gear 40, three first clutch gears 40, three second clutch gears 2, three lock bodies 31, three clutch shafts 6, an output shaft 51, an output Gear 50 and mounting plate 91. Wherein, there are two mounting plates 91 , namely a first mounting plate 911 and a second mounting plate 912 . The two square mounting boards 91 are connected and fixed by the support columns 92 arranged at the four corners. The two mounting plates 91 are parallel to each other. The input gear 40 , the first clutch gear 40 , the second clutch gear 2 , the lock body 31 , the clutch...

Embodiment 3

[0078] This embodiment is a device, specifically a door for a safe. refer to Figure 14, the device includes: a door body 900 , a locking device 910 , a handle 920 , a door latch 930 and a rotating telescopic conversion mechanism 940 . The locking device 910 is the multi-lock and two-open locking device in the first or second embodiment. The locking device 910 is disposed on the door body 900 . The input shaft 41 of the locking device 910 is connected to the handle 920 . The output shaft 51 of the locking device 910 is connected to the door bolt 930 through a rotating telescopic conversion mechanism 940 . The rotation telescopic conversion mechanism 940 is used to convert the rotation of the output shaft 51 into the linear reciprocating motion of the door bolt 930 , so that when the output shaft 51 rotates, the door bolt 930 can be driven to expand and contract. In this embodiment, the output shaft 51 is a long rod, and the two ends pass through the locking device 910 resp...

Abstract

The invention discloses a multi-lock two-unlocking locking device and equipment. The locking device comprises an input gear, an output gear, N lock bodies, N x (N-1) / 2 first clutch gears, N x (N-1) / 2 second clutch gears, a first clutch group, a second clutch group and a lock body driving group. The input gear is connected with the input shaft. The output gear is connected with an output shaft. The lock bodies are connected with the first clutch gears and the second clutch gears through N-1 driving parts. And the first clutch gears and the second clutch gears are correspondingly arranged on N * (N-1) / 2 clutch shafts. And the first clutch gears and the second clutch gears are correspondingly provided with a separation position and a meshing position on the clutch shaft. When the lock bodies are in the closed state, the first clutch gears or the second clutch gears connected with the lock bodies move to the separation position. When the lock bodies are in the open state, the first clutch gears and the second clutch gears which are connected with the lock bodies move to the meshing position. Therefore, the locking device can be opened as long as any two locks are opened.

Description

technical field [0001] The invention relates to a locking device, in particular to a multi-lock and multi-open locking device. Background technique [0002] The treasury standard requires that the treasury door adopts a structure of at least three openings and two openings, that is, any two of the three locks can be opened to open the vault door, which can solve the problem of fault tolerance of the vault door lock. That is, under this structure, the vault door can still be opened if one of the locks is damaged. This ensures the security of the vault. [0003] CN 110939323 A discloses a three-lock and two-opening lockset capable of realizing the three-opening and two-opening structure required by the above-mentioned vault door. But there is a defect in this technical scheme: when one of the locks is opened, turning the handle can retract the lock bolt by half, and now the locking length of the lock bolt does not meet the vault standard. Contents of the invention [0004...
