Detailed Description

As shown in fig. 1 and 2, the novel automatic latch device comprises a housing 1, a motor 10 and a transmission block 12, when a password is input correctly, the motor 10 can drive the transmission block 12 to move, and the transmission block 12 drives the latch to move, so that unlocking is realized.

In order to drive the transmission block 12 to move, the invention is that the transmission block 12 is arranged in a shell 1 in a sliding way, a first rack 5 is arranged in the shell 1 in a sliding way, the first rack 5 is connected with the transmission block 12 in a transmission way, a lower gear 9 and an upper gear 7 are arranged in the shell 1, the upper gear 7 is connected with a motor 10 in a transmission way, the lower gear 9 is meshed with a transition gear 11, the transition gear 11 is meshed with the first rack 5, as shown in figure 4, the inner hole of the lower gear 9 is provided with a spline surface 90, the spline surface 90 faces upwards and is provided with a through hole 91, the upper gear 7 is provided with a spline groove 70, a clutch piece 8 is arranged between the lower gear 9 and the upper gear 7, the lower end surface of the clutch piece 8 is provided with a lower spline part 81, the lower spline part 81 can be in spline connection with the spline surface 90 of the lower gear 9, the upper end of the clutch piece 8 is provided with an upper spline part 80, the upper spline part 80 is in spline connection, as shown in fig. 2, the emergency pulling member 3 is located below the lower gear 9, the emergency pulling member 3 is connected with a second rack 6, the second rack 6 can be meshed with the lower gear 9, as shown in fig. 4, a groove 30 is formed in the emergency pulling member 3, a pushing member 4 is arranged in the groove 30, the pushing member 4 penetrates through a through hole 91 of the lower gear 9 and abuts against the clutch member 8, the bottom of the pushing member 4 is in inclined plane fit with the groove 30 of the emergency pulling member 3, as shown in fig. 3, a pressure spring 16 is arranged in the housing 1, and the pressure spring 16 acts on the clutch member 8 from the upper side.

The working principle of the novel automatic locking bolt device is as follows: when the password is input correctly, the motor 10 drives the upper gear 7 to rotate, and as the upper gear 7 is connected with the lower gear 9 through the clutch part 8, the lower gear 9 rotates along with the upper gear, the lower gear 9 rotates to drive the first rack 5 to move through the transition gear 11, and the first rack 5 drives the transmission block 12 to move, so that unlocking is realized. When a motor 10 or a circuit is in failure, emergency unlocking is realized through a mechanical lock, a key is inserted to rotate a lock cylinder of the mechanical lock, so that an emergency pull piece 3 is driven to move, the emergency pull piece 3 moves to drive a push piece 4 to move, because a groove 30 of the emergency pull piece 3 is matched with a bottom inclined plane of the push piece 4, when the emergency pull piece 3 moves, the push piece 4 is pushed to move upwards through the inclined plane, the push piece 4 penetrates through a through hole 91 of a lower gear 9 to be abutted against a clutch piece 8 and pushes the clutch piece 8 to move upwards, so that a lower spline part 81 of the clutch piece 8 is separated from a spline surface 90 of the lower gear 9, at the moment, the lower gear 9 rotates to not drive an upper gear 7, the emergency pull piece 3 continues to move, a second rack 6 on the emergency pull piece 3 is meshed with the lower gear 9, so that the lower gear 9 is driven to rotate, the lower gear 9 drives a first rack 5 to move, and the first rack 5 drives, thus, emergency unlocking is realized. After the emergency unlocking is completed, the emergency pull piece 3 resets, the pushing piece 4 enters the groove 30 of the emergency pull piece 3 again, the clutch piece 8 moves downwards under the action of the pressure spring 16, the lower spline part 81 of the clutch piece 8 and the spline surface 90 of the lower gear 9 are closed again, and when the motor 10 or a circuit is repaired, the motor 10 can normally realize unlocking.

Since the transmission block 12 is in transmission connection with the first rack 5, if the transmission block 12 is damaged by external force, the transmission block 12 will react on the first rack 5, so that the gears are easily damaged, and the lock bolt is easily opened by force. In order to improve the safety, as shown in fig. 5 and 6, in the present invention, a fixture block 2 is disposed in a housing 1, the fixture block 2 has a limiting portion 20 for limiting a driving block 12, the fixture block 2 is slidably disposed in a slot of the housing 1, a spring 15 acting on the fixture block 2 is disposed in the slot, a first rack 5 is engaged with an inclined surface of the fixture block 2 and can push the fixture block 2 to move toward a direction of the spring 15, the driving block 12 has an unlocking slot 120 for allowing the limiting portion 20 of the fixture block 2 to enter, the first rack 5 has a toggle block 50, the driving block 12 has a toggle slot, and the toggle block 50 is located in the toggle slot. When the first rack 5 moves, the first rack 5 is matched with the inclined surface of the fixture block 2 and pushes the fixture block 2 to move towards the direction of the spring 15, the first rack 5 continues to move, the limiting part 20 of the fixture block 2 enters the unlocking groove 120 of the transmission block 12, so that the limiting part 20 of the fixture block 2 no longer limits the transmission block 12, and the first rack 5 continues to move and then stirs the transmission block 12 to move through the stirring block 50, so that unlocking is realized. When the driving block 12 is pried by the outside, the fixture block 2 can effectively prevent the driving block 12 from moving, thereby preventing the lock bolt from being violently opened.

Finally, it should be mentioned that, in order to accurately control the movement of the transmission block 12, the transmission block 12 is provided with a stroke block 121, and two sides of the stroke block 121 are respectively provided with a first stroke switch 13 and a second stroke switch 14, and both the first stroke switch 13 and the second stroke switch 14 are electrically connected with the motor 10. When the stroke block 121 on the transmission block 12 contacts the first stroke switch 13 or the second stroke switch 14, the motor 10 stops outputting, so that the movement of the transmission block 12 driven by the motor 10 can be accurately controlled.
