A kind of fingerprint acquisition instrument whirligigTechnical field
The present invention relates to the fingerprint acquisition instrument using on finance device, particularly to the whirligig of fingerprint acquisition instrument.
Background technology
At present, some finance devices are both provided with fingerprint acquisition instrument, are easy to customer self-service and handle required business, existingFingerprint acquisition instrument is all directly to be connected on finance device, and therefore, its placement direction has been fixed it is impossible to change it is impossible to rootAccording to client's actual demand anglec of rotation, reduce Consumer's Experience sense.
Content of the invention
The present invention is intended to provide a kind of whirligig making fingerprint acquisition instrument rotate, improve the experience sense of client.
A kind of fingerprint acquisition instrument whirligig of the present invention, including the panel with first through hole, and and panelIt is connected and the concave shape mounting bracket with the second through hole, formed between the groove of described concave shape mounting bracket and panel and houseSpace, in receiving space, can be arranged in receiving space with respect to the rotational structure of receiving space rotation, described rotational structureIncluding the first installing plate, and the second installing plate connecting as one with the first installing plate, the first installing plate is placed in the of panelOne through hole, is respectively arranged with the square through hole coaxial with first through hole on described first installing plate and on the second installing plate, refers toLine Acquisition Instrument panel is arranged at the square through hole on the first installing plate, and another surface of described second installing plate is also equipped withFingerprint acquisition instrument circuit board, the 3rd installing plate with third through-hole and the second installing plate are connected, by fingerprint acquisition instrument circuit boardIt is pressed on the second installing plate, be connected with driving gear at the third through-hole of described 3rd installing plate, driving gear is fixed withConnecting shaft, described concave shape mounting bracket bottom surface is fixed with ring flange, and ring flange is connected with beam barrel, and character cut in bas-relief is inserted in beam barrel one endIn second through hole of shape mounting bracket, the connecting shaft on described driving gear stretches in the beam barrel cylinder of corresponding end, described connectionThere is gap, described driving gear side is provided with the damping gear being meshed therewith, damping between axle outer wall and beam barrel cylinder inwallGear is rotatably installed in concave shape mounting bracket.
A kind of fingerprint acquisition instrument whirligig of the present invention, because rotational structure can panel and concave shape be installed relativelyHolder pivots, and driving gear is meshed with damping gear, therefore, need to rotate fingerprint according to oneself actual demand in client and adoptDuring collection instrument, only need to directly rotate the first installing plate with hand, then the first installing plate drive fingerprint acquisition instrument panel, the second installing plate,Fingerprint acquisition instrument circuit board, the 3rd installing plate and driving gear rotate, and because driving gear is engaged with damping gear, becauseThis, after going to angle needed for client, client stops operating the first installing plate, then by the self-characteristic of damping gear, can makeFingerprint acquisition instrument stops on this position, so that client uses, meets the demand for experience of client；And the connection due to driving gearAxle with stretch in beam barrel, and between the connecting shaft outer wall of beam barrel inwall and driving gear, have gap, therefore, driving tooth can ensuredMoreover it is possible to make whole rotational structure have support in the case of wheel normal rotation.

Specific embodiment
A kind of fingerprint acquisition instrument whirligig, as shown in Figure 1 to Figure 3, including the panel 2, Yi Jiyu with first through hole 1Panel 2 is connected and the concave shape mounting bracket 4 with the second through hole 3, the groove of described concave shape mounting bracket 4 and panel 2 itBetween formed receiving space, in receiving space, can with respect to receiving space rotation rotational structure be arranged in receiving space, instituteState rotational structure and include the first installing plate 5, and the second installing plate 6 connecting as one with the first installing plate 5, the first installing plate5 are placed at the first through hole 1 of panel 2, are respectively arranged with and first through hole 1 on described first installing plate 5 and on the second installing plate 6Coaxial square through hole 7, fingerprint acquisition instrument panel 8 is arranged at the square through hole 7 on the first installing plate 5, described second installationIt is also equipped with fingerprint acquisition instrument circuit board 9, the 3rd installing plate 11 and second with third through-hole 10 is pacified on another surface of plate 6Dress plate 6 is connected, and fingerprint acquisition instrument circuit board 9 is pressed on the second installing plate 6, the third through-hole 10 of described 3rd installing plate 11Place is connected with driving gear 12, and driving gear 12 is fixed with connecting shaft 13, and described concave shape mounting bracket 4 bottom surface is fixed with methodBlue disk 14, ring flange 14 is connected with beam barrel 15, and beam barrel 15 one end is inserted in the second through hole 3 of concave shape mounting bracket 4, describedConnecting shaft 13 on driving gear 12 stretches in beam barrel 15 cylinder of corresponding end, described connecting shaft 13 outer wall and 15 inwalls of beam barrelBetween have gap, described driving gear 12 side is provided with the damping gear 16 being meshed therewith, and damping gear 16 is rotatableIt is installed in concave shape mounting bracket 4.
The edge of described second installing plate 6 is provided with multiple flanges 17 by annular array, and described panel 2 is provided with M wordShape stop bit shell fragment 18, the groove of described M font stop bit shell fragment 18 flange 17 towards on the second installing plate 6 edge, flange 17 withWhen second installing plate 6 turns to the groove of M font stop bit shell fragment 18, flange 17 snaps in the groove of M font stop bit shell fragment 18,Thus it is more stable fingerprint acquisition instrument can be made further to stop on required angle position, will not rotate, according to adjacent ribs 17Angle setting, fingerprint acquisition instrument can be made to rest on the positions such as 0 °, 45 °, 90 °, 135 ° and 180 °, strengthen user operation bodyTest sense.
L-shaped limit base 19 is provided with the groove floor of described concave shape mounting bracket 4, right on described 3rd installing plate 11Claim to be provided with two limited posts 20, limited post 20 turns to the L-shaped limit base in concave shape mounting bracket 4 with the 3rd installing plate 11Joint therewith at 19, thus can avoid the frequent one direction of fingerprint acquisition instrument to rotate, it is to avoid fingerprint acquisition instrument and outside wiringIt is pulled off.
Be provided with concave surface 21 on described first installing plate 5, client when needing to rotate fingerprint acquisition instrument, by by finger buckleEnter in the concave surface 21 on the first installing plate 5, you can ease rotation rotational structure.
It is additionally provided with rubber sheet gasket 22, it is to avoid the second installing plate between described fingerprint acquisition instrument panel 8 and the second installing plate 66 when being pressed on the first installing plate 5, damages fingerprint acquisition instrument panel 8 by pressure.
