The file cabinet that a kind of file automatic spring suspends
Technical field
The present invention relates to a kind of file cabinet.
Background technology
File cabinet accounts for critical role in desk job, takes frequent operation.And in prior art, office must
It is separate two equipment between standby computer and file cabinet.If able to as operation electronic record,
Complete the lookup of files in cabinet on computers and transfer, office process will be brought great convenience.
Summary of the invention
It is an object of the invention to provide a kind of file cabinet, required file can be transferred according to instruction is fast automatic.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is, a kind of file automatic spring suspends
File cabinet, including being provided with the file cabinet of some drawers, file is placed in described drawer, it is characterised in that
Affixed first calutron in described drawer back, affixed second calutron of correspondence position of file cabinet, first
The like pole of calutron and the second calutron is oppositely arranged, and produces reaction force and makes drawer eject;Institute
The memory location of several files, the bottom of each memory location it is divided into be provided with the 3rd calutron in stating drawer,
The bottom of each file is provided with the 4th calutron, the 3rd calutron and the same sex magnetic of the 4th calutron
Pole is oppositely arranged, and produces reaction force and makes file eject and suspend;Each calutron is provided with single-chip microcomputer, single
Sheet machine communication connection control systems, is switched on or switched off the power supply of calutron according to the instruction of control system.
Using technique scheme, user only needs computation, it is possible to complete transferring of respective document,
Transfer the files without artificial lookup, be very easy to desk job.
With improvement, described first calutron and/or the second calutron are provided with lead limit switch.At drawer
Arrive precalculated position calutron to quit work.
Preferably, each calutron uses wireless power conveying mechanism supply power supply.Wireless power transmission technology
Being to utilize wireless means, converting electrical energy into becomes radio wave and sends, and is being received by specific
Radio wave is collected and is converted to electric power by device, for people to use.As the Massachusetts Institute of Technology invents
Wireless power transmission technology utilizes " magnetic coupling resonance " principle to realize wireless power exactly.
Preferably, with bar code on described file, bar code scanner, bar shaped at file cabinet, it are provided with
Code scanning means communication connection control systems.So that control system automatically updates folder information.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is embodiment overall structure schematic diagram;
Fig. 2 is drawer overall structure schematic diagram;
Fig. 3 is drawer side-looking partial structurtes view.
Specific embodiment
Seeing accompanying drawing, a kind of concrete structure of the reflection present invention, described file cabinet 1 is provided with some drawers 2, literary composition
Part folder 3 is placed in described drawer 2, affixed first calutron 8 in described drawer 2 back, file cabinet 1 right
Answering affixed second calutron 7 in position, the first calutron 8 is relative with the like pole of the second calutron 7
Arrange, produce reaction force and make drawer 2 eject along drawer rail 9;Described first calutron 8 and second
Calutron 7 is provided with lead limit switch (being not drawn in figure), accurately to control the stroke of drawer 2.
The memory location 4 of several files 3, the bottom of each memory location 4 it is divided into be provided with in described drawer 2
Three calutrons 5, the bottom of each file 3 is provided with the 4th calutron 6, the 3rd calutron 5 and
The like pole of four calutrons 6 is oppositely arranged, and produces reaction force and makes file 3 eject and suspend;Respectively
Calutron is provided with single-chip microcomputer, and single-chip microcomputer radio communication connects computer or the control system of single-chip microcomputer composition, root
The power supply of calutron it is switched on or switched off according to the instruction of control system.Each calutron uses wireless power conveying
Mechanism's supply power supply.With bar code on file 3, file cabinet 1 is provided with bar code scanner, bar shaped
Code scanning means radio communication connection control system.File directory, and and file can be automatically updated after scanning
Folder binding, it is to avoid be manually entered filename worried.
Use technique scheme, in computer or the file 3 controlling to select to need in software of single-chip microcomputer, control
System processed selects corresponding drawer 2 to launch signal specific according to file 3 location, the first electromagnetic installing
Put 8 and second calutron 7 open energising, electricity magnetisation produce reaction force makes drawer 2 eject, drawer 2
(reasonable time delay can be used or use the ejection of the method identification drawers 2 such as limit switch) after ejection, institute
Needing file 3 to receive signal, the 3rd calutron 5 and the 4th calutron 6 are opened, and make required file 3
It is suspended in certain altitude.Communication and electric power conveying between control system and file cabinet all use wireless mode,
Structure is simplified, it is to avoid circuit weares and teares, can make to have when heap file needs to transfer can fast automatic find out required
File.
The above-mentioned implementation that the present invention describes is not merely to clearly illustrate technical scheme, and not
It is understood that as the present invention being made any restriction.The present invention the art have known multiple replacement or
Person deforms, and on the premise of without departing from essential meaning of the present invention, each falls within protection scope of the present invention.
