[0002] At present, although the known mechanical locks have general safety functions, the existing mechanical locks generally only have one key. Even if there are two types of keys, two keys must be used to open the lock. A mechanical shared lock that can be opened by using any two of them with different keys. If there are some important resources that can be used by three people, but cannot be used by one person alone, at least two people can use it together, then such a lock is needed mechanical shared lock to complete

Embodiment Construction
[0020] exist Figure 8 In the middle, the lock cylinders A, B, C are locked (such as Figure 6 As shown), the middle layers A2, B2, and C2 of the lock cylinder are just blocked in the holes a, b, and c of the lock cylinder on the connecting rod. At this time, the connecting rod 4 cannot do any sliding, so the door bolt 3 cannot be used. Any sliding, shared lock is locked. When any one of the lock cylinders A, B, and C is open (such as Figure 7 As shown), the middle layer of the lock cylinder just leaves the lock cylinder hole on the connecting rod. At this time, because there are two lock cylinders locked in the lock cylinder hole on the connecting rod, the connecting rod 4 cannot do any Sliding, door bolt 3 just can not do any sliding, shared lock is in locked state. When any two of the lock cylinders A, B, and C are open (such as Figure 7 As shown), the middle layer of the lock cylinder just leaves the lock cylinder hole on the connecting rod. At this time, because the...

The invention provides a two-out-three mechanical shared lock which is a mechanical device shared by people and can be opened by two optional keys out of three different keys. The mechanical shared lock has the advantages that due to the fact that only one key in the same kind is provided, a trouble caused by keeping spare keys in the past or a safety problem caused by losing spare keys is solved, and a risk of incapability of unlocking a lock is avoided when keys are lost and no spare keys are provided; abuse of right of use is avoided when the right of use is too concentrated, and three persons can use the two-out-three mechanical shared lock together and can monitor one another; a defect that one kind of keys or two kinds of keys together are required to be used for a lock is overcome; and an idea of levers and rotation is mainly adopted, and three lock cylinder units matched mutually are used for controlling a bolt, so that production cost of using a plurality of locks and a multi-lock linkage mechanism is reduced. The two-out-three mechanical shared lock is reasonable in structure, ingenious in design, simple to produce, low in cost, convenient to assemble and easy to popularize.
Description
technical field [0001] The invention relates to a new type of mechanical device shared by multiple people, especially having the function of opening a mechanical shared lock by using any two of three different keys. Background technique [0002] At present, although the known mechanical locks have general safety functions, the existing mechanical locks generally only have one key. Even if there are two types of keys, two keys must be used to open the lock. A mechanical shared lock that can be opened by using any two of them with different keys. If there are some important resources that can be used by three people, but cannot be used by one person alone, at least two people can use it together, then such a lock is needed Mechanical shared lock to complete. The advantages brought by such a mechanical shared lock are (1), each kind of key has only one, overcomes the inconvenience that the spare key is kept in the past, or brings safety problems because of the loss of the spar...
