The electric energy meter prefabricated card-inserting device
Technical field
The present invention relates to a kind of prefabricated card-inserting device.
Background technology
At present, for the single-phase electric energy meter to the band draw-in groove carries out the data change operation, just need a specific I C card and ammeter to communicate.Our IC-card that can only will be connected with data line through the mode of manual work was inserted in the draw-in groove of electric energy meter in the past, and will certainly there be problems such as insecurity, efficient are low, labour cost increase in such mode.The automatic inserted IC card device that also occurred a kind of vertical direct plugging-in afterwards, but because having certain gradient, the IC-card draw-in groove make the IC-card that is inserted into be easy to by bending by force, very big to the IC-card injury tolerance.
Summary of the invention
The technical matters that the present invention will solve and the technical assignment of proposition are that the prior art scheme is improved and improved, and a kind of electric energy meter prefabricated card-inserting device are provided, to reach automatic, safe socket IC-card purpose.For this reason, the present invention takes following technical scheme.
The electric energy meter prefabricated card-inserting device is characterized in that: it comprise support body, vertically be fixed in support body substrate, be located at being used on the substrate drive driven unit that IC-card moves up and down and with oblique guide surface with the oblique mobile guidance set of guiding IC-card, be located at being used on the driven unit and provide the adjusting part of snap-in force between IC-card and the oblique guide surface, be connected with driven unit be used for the control device that the controlling and driving assembly moves.Control device is used for the action of controlling and driving assembly; IC-card is located on the driven unit, and when driven unit descended, IC-card was pressed on the oblique guide surface and under oblique through adjusting part and moves, and realizes the purpose of automatic oblique plug-in card.Adjusting part provides left and right displacement space simultaneously.Improved work efficiency, oblique plug-in card is avoided the IC-card bending damage.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature.
Described driven unit comprises the gib block that is fixed in pressing plate in the cylinder that is fixed in support body, the pressing plate that is connected with the cylinder piston rod lower end, upper surface, vertically is fixed in the guide rail of substrate, the card mounting blocks that is fixed in gib block and the slide block that is slidingly connected with guide rail, is connected with pressing plate, and the right flank of described card mounting blocks is that the card under oblique is installed the inclined-plane.Being provided with of guide rail guarantees that pressing plate can move up and down by straight line, prevents double swerve, improves the accuracy that moves.The card of card mounting blocks is installed fixedly IC-card of inclined-plane, makes IC-card keep fixing grafting angle.
Described guidance set comprises first bootstrap block and second bootstrap block that is fixed in substrate, and the left surface of described first bootstrap block is with card mounting blocks card the relative oblique guide surface in inclined-plane to be installed; Described second bootstrap block is provided with oblique guiding groove, and the slope of guiding groove is identical with the first bootstrap block guide surface; The oblique below that second bootstrap block is positioned at first bootstrap block can be positioned on the straight line guiding groove and guide surface.First bootstrap block and second bootstrap block are fixed on the substrate as reference for installation with gib block, and when piston rod moved down, pressing plate descended, and guide ribs vertically moves down along guide rail.The guiding groove of second bootstrap block guarantees that IC-card obtains guiding and support when inserting the electric energy meter draw-in groove, avoids the card distortion impaired, the life-span of improving card.
Pressing plate is provided with the open slot to open front that runs through upper and lower surfaces.The opening of open slot be positioned at pressing plate near substrate-side; When driven unit moves down, when pressing plate descends, in open slot, pass first bootstrap block, avoid the interference of first bootstrap block and pressing plate, improve the distance that IC-card moves down.
The right flank of described open slot is equal with the left surface of gib block, and the pressing plate on open slot right side is provided with two horizontal " U " shape grooves, wears the screw that is spirally connected with gib block in the groove.
The oblique guide surface of described first orienting lug is offered vertical locating slot; The card of described card mounting blocks is installed the inclined-plane and is connected two rectangle locating pieces that match with first orienting lug side by side; At least one slide block embeds in the locating slot of first orienting lug, and screw passes locating piece and is spirally connected with the card mounting blocks.Locating slot play the guiding role, and prevents to be shifted before and after the IC-card.
Described adjusting part comprise one be fixed in the pressing plate lower surface regulating block, two bolts that connect regulating block and card mounting blocks, be socketed in the spring on the bolt; Regulating block is positioned at the left side of card mounting blocks, and bolt is spirally connected with the screw of being located on the card mounting blocks after passing the bolt hole be located on the regulating block and socket spring.Adjusting part is avoided because of processing and is assembled the left and right lateral error that is produced, and when undesirable, can carry out lateral adjustments.
Described substrate is provided with a plurality of driven units, guidance set and adjusting part.
Beneficial effect: invention realizes automatic oblique plug-in card, and operating personnel needn't contact with charged electric energy meter, guarantees the security of work, increases work efficiency, and oblique plug-in card is avoided the IC-card bending damage, improves the mission life of IC-card, reduces cost.
