Detailed Description
As shown in fig. 1, the safe electric latch comprises a housing 1, a motor 3 and a latch head 2. The motor 3 and the bolt head 2 are both arranged in the shell 1.
As shown in fig. 2 and fig. 1, a bolt head sliding slot 10 is formed in the housing 1, and the bolt head 2 is slidably disposed in the bolt head sliding slot 10, that is, the bolt head 2 can slide in the bolt head sliding slot 10 and move in and out of the housing 1. When the bolt head 2 comes out of the shell 1, the bolt can be limited, so that the bolt locks the door; when the bolt head 2 retracts into the shell 1, the limit of the bolt is released, and the bolt is not locked when the door handle is rotated. In order to shift the bolt head 2, as shown in fig. 2, a shifting chute 11 parallel to the bolt head chute 10 is arranged in the housing 1, a shifting member 4 is slidably arranged in the shifting chute 11, the shifting member 4 is in transmission connection with the motor 3, and the shifting member 4 is in transmission connection with the bolt head 2 through a transmission spring 7; through the drive of motor 3, stir the piece 4 and remove and just can drive the bolt head 2 through transmission spring 7 and remove. Of course, when the bolt head 2 extends out of the housing 1, it needs to be limited, for this purpose, a limiting chute 12 perpendicular to the toggle chute 11 is arranged in the housing 1, a limiting piece 5 is slidably arranged in the limiting chute 12, the limiting piece 5 has a limiting part 50 for limiting the movement of the bolt head 2, and the limiting piece 5 has a first inclined surface 51, as shown in fig. 3, the toggle piece 4 has a pushing inclined surface 40 acting on the first inclined surface 51 to drive the limiting piece 5 to move; when the toggle member 4 moves downward, the first inclined surface 51 of the limiting member 5 is acted on by the pushing inclined surface 40 of the toggle member 4, so that the limiting member 5 moves to the left, the limiting part 50 of the limiting member 5 no longer limits the bolt head 2, and the bolt head 2 retracts under the tension of the transmission spring 7, so that the bolt head 2 enters the housing 1. The reason that the toggle piece 4 and the bolt head 2 are in transmission connection by the transmission spring 7 is that the toggle piece 4 needs to move a certain distance to push the limiting piece 5 to one side to remove the limitation, the transmission spring 7 can be deformed to generate tensile force in the moving process of the toggle piece 4, and when the limiting piece 5 is removed from the limitation, the transmission spring 7 can immediately pull the bolt head 2 to retract. And a return spring 6 for urging the restriction member 5 to return is provided at the rear end of the restriction member 5 in order to return the restriction member 5.
The working principle of the safe electric lock bolt is as follows: when the safe is in the locked state, as shown in fig. 4, the stopper portion 50 of the stopper 5 restricts the bolt head 2 so that the bolt head 2 cannot move, thereby bolting the bolt. When the unlocking is needed, the fingerprint or the password is matched, the motor 4 drives the toggle piece 4 to move, as shown in fig. 3, the toggle piece 4 pushes the inclined surface 40 to act on the first inclined surface 51 of the limiting piece 5, so that the limiting piece 5 moves towards the left side, the limiting part 50 of the limiting piece 5 no longer limits the bolt head 2, meanwhile, the toggle piece 4 pulls the bolt head 2 to move downwards through the transmission spring 7, and when the limiting part 5 of the limiting piece 5 is completely released, the bolt head 2 enters the shell 1, and the unlocking is achieved. When the lock needs to be locked again, the motor 3 rotates reversely, the stirring piece 4 moves back, the stirring piece 4 drives the bolt head 2 to move outwards, the limiting piece 5 resets under the action of the reset spring 6, the bolt head 2 is limited again, and therefore the bolt head 2 locks the lock bolt again.
In order to enable an emergency unlocking in case of a possible malfunction of the motor 3 or the electric circuit, an emergency unlocking member 9 is further provided in the toggle chute 11, as shown in fig. 5, the limiting member 5 has a second inclined surface 52, and the emergency unlocking member 9 has a pushing portion 90 acting on the second inclined surface 52 to drive the limiting member 5 to move. When emergency unlocking is required, the emergency unlocking piece 9 is pulled through the emergency mechanical lock, the pushing part 90 of the emergency unlocking piece 9 firstly acts on the second inclined surface 52 of the limiting piece 5 to move the limiting piece 5 to the left side, so that the limiting part 50 of the limiting piece 5 is unlocked, as shown in fig. 6, the emergency unlocking piece 9 continues to move, then the pushing part 90 of the emergency unlocking piece 9 pushes the bolt head 2 to move (specifically, acts on the side extension block 25 of the bolt head 2, the side extension block 25 can be of an integral structure with the bolt head 2, can be welded or connected to the bolt head 2 through other existing connecting methods, and the limiting part 50 of the limiting piece 5 also acts on the side extension block 25 of the bolt head 2 to realize limiting), so that the bolt head 2 enters the shell 1, and therefore, the emergency unlocking is realized.
As shown in fig. 1 and 3, the motor 3 is in transmission connection with the toggle element 4 through a transmission gear 8, the toggle element 4 has a tooth surface 41, and the transmission gear 8 is engaged with the tooth surface 41 of the toggle element 4. The transmission gear 8 can be provided with a plurality of gears 8 with different diameters, and the plurality of gears 8 are meshed together to achieve the purpose of speed reduction.
As mentioned above, the toggle element 4 moves the bolt head 2 via the transmission spring 7. The transmission spring 7 can be only provided, one end of the transmission spring is connected with the poking piece 4 (clamped or welded), and the other end of the transmission spring is connected with the bolt head 2 (clamped or welded), but the structure is troublesome to connect, and the connection part is easy to disconnect. In order to facilitate assembly and obtain a more stable structure, the inner end of the bolt head 2 is provided with a connecting column 20, the connecting column 20 penetrates through the extending part 42 of the stirring part 4, the tail end of the connecting column 20 is provided with a supporting end 21, the number of the transmission springs 7 is two, the two transmission springs 7 are sleeved on the connecting column 20, one of the two transmission springs is arranged between the extending part 42 of the stirring part 4 and the bolt head 2, and the other transmission spring is arranged between the extending part 42 of the stirring part 4 and the supporting end 21 of the connecting column 20. When the shifting piece 4 is pulled back, the transmission spring 7 positioned between the extension part 42 of the shifting piece 4 and the support end 21 of the connecting column 20 pushes the bolt head 2 to retract; when the shifting piece 4 moves forwards, the transmission spring 7 between the extension part 42 of the shifting piece 4 and the bolt head 2 pushes the bolt head 2 to move forwards. Through the structure, the two transmission springs 7 only need to be sleeved on the connecting column 20 without end connection, so that the structure is more stable, and the assembly is more convenient.
