Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model；The technical scheme in the embodiment of the utility model is carried out Clearly and completely describe；Obviously；The described embodiments are only a part of the embodiments of the utility model；Rather than whole Embodiment.Based on the embodiments of the present invention；Those of ordinary skill in the art are without making creative work Every other embodiment obtained；It fall within the protection scope of the utility model.

Please refer to Fig. 1-5, a kind of CAD Graphing of Engineering protective device based on computer encryption, including ontology 1, under ontology 1 Side is provided with universal wheel 2, and the top of universal wheel 2 connects cord 3, and cord 3 passes through 1 bottom of ontology and connects the first conductor 4, and first leads Body 4 is electrically connected battery 5, and battery 5 is also electrically connected alarm 6, and alarm 6 is electrically connected the second conductor 7, and the first conductor 4 is located at Second conductor, 7 top.

1 side of ontology is fixedly connected with fixing layer 8,8 no-top plate of fixing layer and bottom plate, and inside is filled with sponge 9, fixing layer 8 Foreboard 10 be provided with strip aperture of door 11, the back plate 12 of fixing layer 8 is provided with gate slot 13, is provided with hold-down bars in gate slot 13 14, one end of hold-down bars 14 is located inside back plate 12, and one end of the hold-down bars 14 inside back plate 12 is provided with limit plate 15, Spring 16 is provided between limit plate 15 and gate slot 13, hold-down bars 14 connects filament 17 far from one end of gate slot 13, and filament 17 passes through It connect through ontology 1 with the second conductor 7 after pulley 18, is extended in gate slot 13 after fixed door insertion strip aperture of door 11.

It is provided with electric controlled door 19 before ontology 1, fingerprint identification device 20, fingerprint identification device 20 are provided on electric controlled door 19 It is electrically connected with control device, control device is electrically connected battery 5 and automatically controlled door switch unit.

Working principle:

Firstly, if someone needs to steal Graphing of Engineering, need to open host computer copy either directly will be electric Brain server is taken away；The utility model opens the fixed door on fixing layer, then whole device is fixed on some object, such as Table leg is placed in sponge or some pillar is placed in sponge, is then inserted into fixed door, during insertion, It needs to be always maintained at hold-down bars to be entirely located in back plate, then fixed door is inserted into strip aperture of door, is inserted into gate slot In, hold-down bars pops up limited length at this time, and cord and filament are all relaxed states, and some displacement, which not occurs, will cause report It is alert；It after fixed door insertion, firmly presses, crushes glue layer, to fix fixed door, the spring of state is in elongation at this time State；

When someone thinks mobile the utility model, necessarily need to open fixed door, at this time when fixed door take away it is same When, hold-down bars is extended to gate slot under the action of the spring, so that filament be driven to be displaced, and then make the second conductor horizontal displacement, The bottom of second conductor is connected with the top of the first conductor, causes alarm；

Even someone avoids above-mentioned alarm setting, or does to walk together with fixed object, when doing Can inevitably universal wheel be made to move, when universal wheel is subjected to displacement it is larger when, drive cord to drive the first conductor it is downward, into And the side of the first conductor and the side of the second conductor are connected, cause alarm, normally slightly displacement will not cause universal wheel Alarm, because cord more loosens；

First conductor and the second conductor in the process of moving, are moved in the shifting chute for be located within the body portion, So as to guarantee the displacement route of the first conductor and the second conductor, alarm is realized；

Furthermore it is electric controlled door to be opened by fingerprint identification device, and then open computer master that the utility model, which normally opens host, Machine is also equipped with the opening password of startup password and CAD software in this outdoor main unit, to pass through the protective device and meter of host The computer of calculation machine itself encrypts setting, thus the CAD Graphing of Engineering in protected host comprehensively.

It is described above；The only preferable specific embodiment of the utility model；But the protection scope of the utility model is not It is confined to this；Anyone skilled in the art is within the technical scope disclosed by the utility model；It is practical according to this Novel technical solution and its improvement design is subject to equivalent substitution or change；It should all cover in the protection scope of the utility model It is interior.
