Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-8, the present invention provides a technical solution: the utility model provides a fingerprint unlocking device for multi-door entrance guard, includes main part 1, be connected with handle 2 on the main part 1, handle 2 is used for rotating and opens the entrance guard lock, be provided with thrust unit 3 and fingerprint identification screen 4 in the handle 2, thrust unit 3 is used for opening sliding closure 5, thrust unit 3's output is connected with sliding closure 5, sliding

closure

5 and 2 sliding connection of handle, sliding closure 5 can protect fingerprint identification screen 4 well.

The pushing device 3 comprises a wedge block transmission assembly 6 and a gear transmission assembly 7, a pressing block 8 is connected to the handle 2, the pressing block 8 is connected with the wedge block transmission assembly 6, the wedge block transmission assembly 6 is connected with the gear transmission assembly 7, the output end of the gear transmission assembly 7 is connected with a sliding block 9, and the sliding block 9 is fixedly connected with the sliding cover 5.

The specific implementation mode is as follows: the sliding cover 5 is controlled to open and close through the pressing block 8, when the handle 2 is held by a hand, a forefinger can press the pressing block 8, the pressing block 8 presses downwards to be transmitted to the wedge block transmission assembly 6, then the gear transmission assembly 7 is transmitted, and finally the sliding cover 5 is opened in a sliding mode, so that the door can be opened by directly rotating the handle 2 while one hand is used for scanning, and two-hand operation and other redundant steps are not needed.

The wedge block transmission assembly 6 comprises a first wedge block 10, a second wedge block 11 and a spring 12, the bottom of the pressing block 8 is connected with the first wedge block 10, the first wedge block 10 is in sliding connection with the second wedge block 11, one end of the spring 12 is fixedly connected with one side of the second wedge block 11, and one end, far away from the spring 12, of the second wedge block 11 is connected with the gear transmission assembly 7.

The specific implementation mode is as follows: the first wedge block 10 in the wedge block transmission component 6 is connected with the pressing block 8, when the pressing block 8 is pressed, the first wedge 10 is moved downwards, the first wedge 10 and the second wedge 11 slide through the inclined surfaces of the two ends to move the second wedge 11 towards one end of the spring 12 and simultaneously press the spring 12, because the fixed block 16 at the bottom of the first rack 15 on the gear assembly 7 is connected with the second wedge 11, therefore, the second wedge block 11 can drive the first rack 15 to move, the spring 12 can reset due to no pressure when the pressing block 8 is not pressed by fingers, the spring 12 can reset the second wedge block 11, the second wedge block 11 can reversely push the first wedge block 10 and the pressing block 8 to enable the first wedge block and the pressing block 8 to reset to the original positions, the movement distances of the second wedge block 11 are different due to the difference of the inclination angles of the inclined surfaces of the first wedge block 10 and the second wedge block 11, and the displacement action generated by the pressing block 8 can be amplified by adjusting the inclination angle of the inclined surface.

The gear transmission assembly 7 comprises a first gear 13 and a transmission shaft 14, a first rack 15 is connected to the first gear 13 in a meshed mode, a fixed block 16 is connected to the first rack 15, the fixed block 16 is connected with a second wedge block 11, the first gear 13 is fixed to the middle of the transmission shaft 14, a bearing 17 is connected to a position, close to two ends, of the transmission shaft 14, the bearing 17 is fixedly connected with the inside of the handle 2, two ends of the transmission shaft 14 are connected with a second gear 18, a second rack 19 is connected to the second gear 18 in a meshed mode, and the second rack 19 is fixedly connected with the sliding block 9.

The handle 2 is provided with a groove 20 on the outer side.

The specific implementation mode is as follows: the first rack 15 is connected with the second wedge 11 by the fixed block 16, so the first rack 15 moves, the first rack 15 is meshed with the first gear 13, so the transmission shaft 14 is driven to move, the first gear 13 and the second gear 18 are both fixed on the transmission shaft 14, so the first gear 13 and the second gear 18 move synchronously, but because the second rack 19 and the first rack 15 are in different directions, the moving direction of the second rack 19 is opposite to that of the first rack 15, and the second gear 18 is larger than the outer diameter of the first gear 13, so when the transmission shaft 14 rotates, the moving distance of the second rack 19 is larger than that of the first rack 15, and the ratio of the outer diameters of the second rack 18 and the first gear 13 is larger, the ratio of the moving distance of the second rack 19 and the first rack 15 is larger, so that the large displacement of the sliding cover 5 is generated by the small displacement of the movable block 8 through the adjustment of the wedge inclined plane angle in the wedge transmission assembly 6 and the gear outer diameter ratio in the gear transmission assembly 7 The displacement of the distance, the groove 20 is used to adapt the posture of the fingers holding the handle 2, so that the fingers can hold more comfortably.
