Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated. For the ease of narration, with direction, operator place for front, in cabinet direction for after.
As it is shown in figure 1, this utility model includes front panel, framework 1, input pallet 2 and identifies device. Described input pallet 2 above has baffle plate, in order to better describe internal structure of the present utility model, front panel and baffle plate is removed in Fig. 1. Described front panel has pallet mouth and identification card socket, described input pallet 2 to be positioned at framework 1, and input pallet 2 can be stretched out by front panel pallet mouth, and described front panel identification card socket is corresponding with identifying device slot, is used for inserting identification card. Having tooth bar 3 under described input pallet 2 bottom surface, there is micro machine seat described framework 1 bottom surface, be above provided with micro machine 4, the output shaft of described micro machine 4 connects the first gear 5, and the first described gear 5 engages with tooth bar 3. When micro machine 4 rotates forward unlatching, the first gear 5 rotates forward, and input pallet 2 stretches out, and when micro machine 4 rotates backward unlatching, the first gear 5 rotates backward, and input pallet 2 is regained. Described micro machine 4 control circuit includes intervalometer, its concrete circuit connecting mode is prior art, any realize running the control circuit that namely stops of setting time after micro machine 4 starts and all can apply to this, its object is to prevent input pallet 2 from deviating from outside stroke, physical circuit implementation is not repeated herein.
Described identification device includes having opposite polarity magnetic after electricity-getting switch 6, axis, dynamic plate the 7, first electromagnetism ring 81 and the second electromagnetism ring 82, the first described electromagnetism ring 81 and the second electromagnetism ring 82 are energized. Described electricity-getting switch 6 includes recognition unit and the output unit of data cube computation, and described recognition unit connects with slot, described output unit and two electromagnetism loop circuits.
Need not can adopting low frequency card electricity-getting switch by significantly high outdoor cabinet electricity-getting switch 6 for safe design, by the frequency of recognition unit detection card, if meeting setpoint frequency, output unit is the first electromagnetism ring 81 and the second electromagnetism ring 82 is powered;And for the higher outdoor cabinet of safe design, it can be then card insert type electronic lock, namely described recognition unit is specially the card reader and buzzer that are connected with single chip circuit, described output unit and electromagnetic actuator, described electromagnetic actuator input connects single-chip microcomputer, outfan connects the first electromagnetism ring 81 and the second electromagnetism ring 82, during use, single-chip microcomputer receives card reader input data, and compare, as with default consistent, electromagnetic actuator is then driven to connect the first electromagnetism ring 81 and the second electromagnetism ring 82 circuit, power, as with default inconsistent, then drive buzzer warning. above low frequency card electricity-getting switch and card insert type electronic lock are prior art, and any contact release (identity card) that can realize identifies and all can apply to this with the device of connection circuit. namely when the contact release using restriction is operated, after electricity-getting switch 6 recognition unit identification correctly, output unit connection circuit is powered, and has opposite polarity magnetic after the energising of electromagnetism ring, produces the active force attracted each other, and dynamic plate 7 is attracted rising. the first described electromagnetism ring 81 and the second electromagnetism ring 82 are separately mounted on dynamic plate 7 through axis and framework 1 lower surface, have spring 9 between two electromagnetism rings, and after taking identity card away, electricity-getting switch 6 power-off, spring 9 promotes dynamic plate 7 to move downward reset.
Described framework 1 lower surface has two pilot holes, is provided with two gathering sills in framework 1, and described dynamic plate 7 two ends respectively connect a push rod 10, and described push rod 10 is embedded in gathering sill through pilot hole, and end has continuous latch 13. Described framework 1 two side is respectively rotatably connected to a gear shaft, and on described gear shaft, key is connected to the second gear 11, and push rod 10 is along gathering sill motor process, and latch 13 can be meshed with the second gear 11. The gear shaft of side has a driving lever 12 towards one end of framework 1 inner chamber. Having two travel switches in framework 1, and two travel switches are in driving lever 12 shift motion, owing to travel switch shape matching is little and is blocked, do not show in Fig. 1, its particular location can be determined according to the second gear 11 tooth pitch, driving lever 12 stroke section. Two travel switches are connected with micro machine 4 circuit respectively, rotate forward in order to control micro electric machine 4 and start and reversion startup. After identity card starts electricity-getting switch 6, dynamic plate 7 drives push rod 10 to rise, by latch transmission the second gear 11, gear shaft rotates with, and driving lever 12 triggers the travel switch controlling to rotate forward, when micro machine 4 rotates forward unlatching, first gear 5 rotates forward, input pallet 2 stretches out outside front panel, input equipment exposure and outdoor cabinet, and operator is inputted; When identity card is removed, dynamic plate 7 drives push rod 10 to decline, second gear 11 driven gear axle reversely rotates, driving lever 12 triggers the travel switch controlling reversion, when micro machine 4 rotates backward unlatching, the first gear 5 rotates backward, and input pallet 2 is regained, due to the baffle plate before input pallet 2 and front panel restriction, then cannot carry out input control.
It should be noted that; this utility model has been described in detail by particular of the present utility model; for a person skilled in the art, the various apparent change when without departing substantially from spirit and scope of the present utility model, it carried out is all within protection domain of the present utility model.
