Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments. Referring to fig. 1 to 5, a lock mechanism of a safe comprises a lock body 1 and a bolt 2, wherein a through hole 10 is formed in one side of the lock body 1; the lock bolt 2 is rotatably arranged in the lock body 1, the lock bolt 1 can rotate from a first position to a second position, when the lock bolt is positioned at the first position, the lock bolt extends out of the through hole 10, and at the moment, the whole lock mechanism is in a locking state; when the bolt is located the second position, it stretches into to the lock body 1 inside from through-hole 10, and whole lock mechanism is in the unblock state this moment, be provided with first torsional spring (the attached drawing is not shown) in the pivot of bolt 2 for the trend that the bolt stretches out from through-hole 10.
A locking pin 3 is movably arranged on one side of the bolt 2, and one end of the locking pin 3 is abutted and matched with the bolt 2, so that the bolt 2 is locked at a first position; the other end of the latch bolt 2 is provided with a spring (not shown in the drawings) for elastically biasing the latch bolt, and a slot 30 is formed at one side of the latch bolt 3.
A transmission rod 4 is rotatably arranged in the lock body 1, one end of the transmission rod 4 is inserted into a slot 30 formed in one side of the locking pin 3, a poking rod seat 40 is arranged at the other end of the transmission rod 4, a protruding column 41 is arranged on the end surface of the poking rod seat 40, a poking rod 5 is arranged in the lock body 1, the poking rod 5 is driven by a motor 6 to rotate, the poking rod 5 can be abutted against and matched with the poking rod seat 40 when driven by the motor 6 to rotate so as to poke the transmission rod 4 to rotate around the rotating shaft of the transmission rod 4, and a second torsion spring (not shown in the attached drawing) is arranged on the rotating shaft of the transmission rod 4 and enables the transmission rod 4 to have a tendency of pushing the locking pin 3 to slide towards the locking bolt 2.
