Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1 to Figure 2, for the locking stopping means of a kind of stored value card bucket baffle plate 9 according to the invention, comprise: stepping motor 1, gag lever post 2, stop collar 3, (it is connected with stored value card bucket baffle plate 9 in stored value card bucket rotating shaft 4, as shown in Figure 3 and Figure 4), first sensor 5, second transducer 6, installing rack 7 and position-limited rack 8, wherein said stepping motor 1, described position-limited rack 8, described first sensor 5 is all fixed on described installing rack 7, described second transducer 6 is fixed on the upper end of described position-limited rack 8, the output shaft of described stepping motor 1 is fixed by screw and described gag lever post 2, described stop collar 3 is set on described gag lever post 2, described first sensor 5 is arranged on the below of described gag lever post 2, described second transducer 6 is arranged on the top of described gag lever post 2, described stored value card bucket rotating shaft 4 is provided with a breach, and (size and this breach of described stop collar 3 match, breach in the present embodiment is preferably a U-shaped breach of being sidelong), after the signal of telecommunication received by described stepping motor 1, rotate to an angle, described stop collar 3 can snap on the breach of described stored value card bucket rotating shaft 4, thus reaches the object of locking rotating shaft.
Further, described gag lever post 2 comprises first connecting rod, second connecting rod and the third connecting rod connected successively, and (preferably described first connecting rod and described third connecting rod are cylindric, described second connecting rod is tabular), wherein said first connecting rod is connected with the output shaft of described stepping motor 1, described third connecting rod is arranged with described stop collar 3; Described first connecting rod rotates under the drive of described stepping motor 1 centered by the axle center of its output shaft, then described third connecting rod is driven to rotate by described second connecting rod, after rotating to certain angle, described stop collar 3 can snap on the breach of described stored value card bucket rotating shaft 4, thus reaches the object of locking described stored value card bucket rotating shaft 4.
Further, described stop collar 3 is a hollow cylindrical shape, comprises inner ring and outer shroud, and the large 1mm of radius of third connecting rod described in its inner ring radius ratio.
Further, described position-limited rack 8 upper end is provided with a draw-in groove 81, the extreme higher position that the position of described draw-in groove 81 can reach in the vertical higher than described stop collar 3, and the outer shroud of described stop collar 3 is less than 1mm to the distance of described draw-in groove 81; Described installing rack 7 upper end is provided with a bending edge 71, and described bending edge 71 extends to described position-limited rack 8 direction, and the outer shroud of described stop collar 3 is less than 1mm to the distance of described bending edge 71.When stop collar 3 is subject to external force, owing to there being 1mm gap to be greater than draw-in groove 81 and the distance to bending edge 71 on installing rack 7 on stop collar 3 to position-limited rack 8 between stop collar 3 and gag lever post 2, therefore stop collar 3 is subject to power, and axle is not by radial load.
Further, described first connecting rod is arranged with a limiting plate.Described first sensor 5 and described second transducer 6 detect the positional information of gag lever post 2 by described limiting plate, and are sent to control or the drive system of motor, realize the accurate control to motor thus.
Further, described stop collar 3 is set on described third connecting rod, and is undertaken spacing by jump ring.
Further, described first connecting rod, described second connecting rod and described third connecting rod are one-body molded.
Further, the radius of described third connecting rod is 2mm, and the inner ring radius of described stop collar 3 is 3mm, and the outer shroud radius of described stop collar 3 is 5mm.More preferably, the distance between the outside of described stop collar 3 and described stored value card bucket rotating shaft 4 is minimum is 0.5mm.
The specific works principle of the present embodiment is: stepping motor 1 is fixed to installing rack 7, and the axle of stepping motor 1 is connected with gag lever post 2, and gag lever post 2 other end is connected with stop collar 3, spacing with jump ring, and position-limited rack 8 is fixed on installing rack 7.When the signal of telecommunication received by stepping motor 1, rotate to an angle, stop collar 3 can snap on the breach of stored value card bucket rotating shaft 4, thus reaches the object of locking rotating shaft.When locked, stepping motor 1 power-off just can reach locking object, is arranged so that motor radial direction does not stress now due to gag lever post 2, so just extends electrical machinery life.And stop collar 3 also can protect motor shaft, because stop collar 3 and gag lever post 2 surrounding have 1mm gap, so it can also play the effect of adjustment to a certain extent.Namely stored value card bucket baffle plate 9 locking device described in the present embodiment has simple and practical, and easy to maintenance, the life-span is long, low cost and other advantages.
