FIG. 2 is a schematic structural diagram of the present invention 2 (without the inner sleeve);

fig. 3 is a combination view of the key, the first insert and the second insert.

Detailed Description

As shown in fig. 1, the blade primary and secondary lock includes a lock body, a main key 5 and an emergency key 6. The main key 5 and the emergency key 6 can be inserted into the lock body, the lock cylinder can rotate forwards after the main key is inserted into the lock body, so that mechanical unlocking is achieved, if the coded electronic lock breaks down, the emergency key 6 is inserted into the lock body, the lock cylinder rotates backwards, and therefore the mechanical emergency unlocking part of the coded electronic lock is driven to achieve emergency unlocking.

The structure and working principle of the insert primary-secondary lock are described in detail below.

As shown in fig. 1, the lock body includes a lock housing, an inner sleeve 1 and a lock cylinder. A lock case (not shown) is provided for mounting on the door, an inner sleeve 1 is fixedly mounted in the lock case, and a lock cylinder is provided in the inner sleeve. As shown in fig. 2, the lock core generally comprises a lock core main body 2 and an insert, a plurality of insert grooves 20 are formed in the lock core main body 2, an insert is arranged in each insert groove 20, and a clamping block is further included. In order to solve the deficiency that prior art exists, the utility model discloses an inserted sheet is still including first inserted sheet 3 and second inserted sheet 4, first inserted sheet 3 has first spacing portion 30, second inserted sheet 4 has the spacing portion 40 of second, be equipped with corotation slotted hole 10 and reversal slotted hole 11 on the endotheca 1, corotation slotted hole 10 extends to both sides respectively with reversal slotted hole 11 (stagger about corotation slotted hole 10 and reversal slotted hole 11 promptly, only the part overlaps in the axial), wherein first spacing portion 30 of first inserted sheet 3 is located corotation slotted hole 10, the spacing portion 40 of second inserted sheet 4 is located reversal slotted hole 11. As shown in fig. 3, the master key 5 has teeth for allowing the second stopper portion 10 of the second blade 4 to come out of the reverse rotation slot 11, and the emergency key 6 has teeth for allowing the first stopper portion 30 of the first blade 3 to come out of the forward rotation slot 10.

The working principle is as follows: when the coded electronic lock is normally used, the coded electronic lock is firstly unlocked, then the main key 5 is inserted, and the main key 5 is provided with the tooth patterns which enable the second limiting part 40 of the second inserting piece 4 to come out of the reverse rotation slotted hole 11, so that when the main key 5 is rotated clockwise, the second limiting part 40 of the second inserting piece 4 is not limited, and the first limiting part 30 of the first inserting piece 3 can normally rotate clockwise in the forward rotation slotted hole 10, so that the lock cylinder normally realizes clockwise rotation, and mechanical unlocking is completed. When the electronic password lock has a fault, the emergency key 6 is firstly inserted, and the emergency key 6 is provided with teeth which enable the first limiting part 30 of the first inserting piece 3 to come out of the forward rotation slotted hole 10, so that when the emergency key 6 is rotated anticlockwise, the first limiting part 30 of the first inserting piece 3 is not limited, and the second limiting part 10 of the second inserting piece 4 can normally rotate anticlockwise in the reverse rotation slotted hole 11, so that the lock cylinder normally realizes anticlockwise rotation, and the electronic password lock is assisted to realize mechanical emergency unlocking; the master key 5 is then inserted again, and normal mechanical unlocking is effected as described above. By this configuration, a mechanical lock can be eliminated, thereby reducing the manufacturing cost of the safe.

As shown in fig. 3, the master key 5 and the emergency key 6 have inner teeth 8, and the first insert piece 3 and the second insert piece 4 have an acting portion 9 interacting with the inner teeth 8. The main key 5 and the emergency key 6 act on the action parts 9 of the first inserting sheet 3 and the second inserting sheet 4 through the inner teeth 8, so that the first inserting sheet 3 and the second inserting sheet 4 are pushed to move.
