Detailed Description

As shown in FIG. 1, the shockproof safe box lock bolt comprises a shell 1 and a bolt head 2, wherein the bolt head 2 is rotatably arranged on the shell 1, a bolt outlet for allowing the bolt head 2 to come out is formed in the shell 1, and the bolt head 2 is connected with a torsion spring 20 for driving the bolt head 2 to reset; a limiting block 3 capable of moving longitudinally is arranged in a shell 1 (the longitudinal direction refers to the longitudinal direction in figure 1, the same is applied below), the limiting block 3 has a state of limiting the rotation of the bolt head 2, one end of the limiting block 3 close to the bolt head 2 is provided with a guide inclined plane 31, the other end of the limiting block 3 is acted with a return spring 30, a locking block 4 capable of moving transversely is arranged on one side of the limiting block 3, the limiting block 3 is provided with a locking groove 32, and the locking block 4 is in transmission connection with a motor 10 driving the locking block 4 to enter the locking groove 32.

When the bolt A of the safe is in a locked state, the locking block 4 is clamped in the locking groove 32 of the limiting block 3, so that the limiting block 3 cannot move, the limiting block 3 blocks the bolt head 2 at the moment, the bolt head 2 cannot rotate, the bolt head 2 is partially exposed out of the bolt outlet of the shell 1, and the bolt head 2 bolts the bolt A, so that the door of the safe cannot be opened as shown in fig. 2. When the fingerprint of the safe is unlocked or the password is unlocked, the motor 10 drives the locking block 4 to come out from the locking groove 32 of the limiting block 3, when the door handle is rotated, the bolt acts on the bolt head 2 and drives the bolt head 2 to rotate, because the limiting block 3 is provided with the guide inclined plane 31 at one end close to the bolt head 2 and the limiting block 3 can move longitudinally, under the action of the bolt head 2, the limiting block 31 moves downwards, and because the bolt head 2 rotates (rotates along the anticlockwise direction), the bolt head 2 enters the shell 1 and does not bolt the bolt A any more, as shown in fig. 2, the door of the safe can be opened. When the safe is locked again, the door of the safe is closed, the bolt head 2 is out of the shell 1 again (rotates along the clockwise direction) under the action of the torsion spring 20, the limiting block 3 moves upwards under the action of the return spring 30 and blocks the bolt head 2 again, and the locking block 4 enters the locking groove 32 of the limiting block 3 again under the action of the motor 10.

The driving by the motor 10 may act as a counter shock, however the motor may also fail. In order to realize emergent unblock under the condition that motor 10 breaks down, the utility model discloses still possess emergent unblock function, concrete structure is as follows: a connecting rod 7 is connected between the locking block 4 and the gasket 6, a long groove 11 is arranged in the shell 1, the locking block 4, the connecting rod 7 and the gasket 6 are positioned in the long groove 11 (the three can move transversely in the long groove 11), a movable sleeve 8 is sleeved on the connecting rod 7, a first spring 70 is arranged between the movable sleeve 8 and the locking block 4, a second spring 71 is arranged between the movable sleeve 8 and the gasket 6, and the motor 10 is in transmission connection with the movable sleeve 8; the housing 1 is provided with an emergency part 9 which can move longitudinally, one end of the emergency part 9, which is opposite to the lock block 4, is provided with an emergency part inclined surface 91, the other end of the emergency part 9 acts on the return spring 90, and the lock block 4 is provided with a lock block inclined surface 41, which is opposite to the emergency part inclined surface 91.

The overall working principle is as follows: when the motor 10 works normally, the motor 10 drives the movable sleeve 8 to move leftwards, the movable sleeve 8 acts on the second spring 71, the second spring 71 acts on the gasket 6, and therefore the locking block 4, the connecting rod 7 and the gasket 6 move leftwards together in the long groove 11, the locking block 4 does not lock the limiting block 3 any more, and the door of the safe can be opened; when the motor 10 drives the movable sleeve 8 to move rightwards, similarly, under the action of the first spring 70, the locking block 4, the connecting rod 7 and the gasket 6 move rightwards in the long groove 1 together, so that the locking block 4 enters the locking groove 32 of the limiting block 3, the limiting block 3 is locked, and at the moment, the door of the safe cannot be opened. And when the motor broke down, the emergency 9 (of course, this emergency 9 is connected with the mechanical lock, and the mechanical lock that inserts through the key rotates to drive emergency 9 action), because emergency 9 has emergency inclined plane 91 for the one end of locking piece 4, and locking piece 4 has the locking piece inclined plane 41 relative with emergency inclined plane 91, through the interact on two inclined planes, locking piece 4 is being pushed and is moving left (movable sleeve 8 is motionless), locking piece 4 just comes out from the locked groove 32 of restriction piece 3 like this, and locking piece 4 no longer restricts and pins piece 3. Through the structure, even if the motor 10 fails, the movable sleeve 8 cannot be driven to move left and right, and the door of the safe box can be opened emergently.

In order to enable the motor 10 to drive the movable sleeve 8 to move left and right, the movable sleeve 8 is provided with an extension block 80, the extension block 80 is provided with a tooth surface, a gear is connected to an output shaft of the motor 10, and the gear is meshed with the tooth surface of the extension block. Through the structure, the motor 10 can drive the movable sleeve 8 to move left and right, so that unlocking or locking is realized.

Finally, it is worth mentioning that the utility model discloses a tie head 2 is semi-circular, and the centre of a circle of tie head 2 articulates on casing 1, and semi-circular tie head 2 can make restriction piece 3 keep a position through its cambered surface at the pivoted in-process.
