Detailed description of the invention
The embodiment of the present invention one is as it is shown in figure 1, the computer examination anti-cheating device of this band LED light is provided with
Block cone cylinder 1 and head-shield 2, block cone cylinder and be provided with left side wall 3, right side wall 4 and upper cover plate 5, left side wall
Top edge is connected with the left side edge of upper cover plate, and right side wall top edge is connected with the right side edge of upper cover plate, left side
Wall, right side wall forward edge connect have clip 12, the present embodiment clip be and side plate one elastic clip,
Single clip can also be used to clamp, and the clip of both sides is clamped on the frame of display 6 left and right sides respectively,
Upper cover plate forward edge rides on the upside of display on frame, and left side wall, the distance of right side wall posterior edges are more than people
The width of face and less than left side wall, the distance of right side wall forward edge；Head-shield be respectively with left side wall posterior edges,
The cover plate extended to head part both sides and top that right side wall posterior edges, upper cover plate posterior edges are connected, cover
Plate can be that straight plate surrounds, it is possible to is that curved slab plate surrounds, and the present embodiment is that curved slab surrounds, as long as sheltering from head
Both sides.This device in use, can be fixed on the frame of display both sides by the present invention by clip
On, utilize side plate can block the plagiarism of adjacent seat examination personnel well, cover plate can also simultaneously work as blocking to
The effect of the sight line of both sides, but also can avoid light irradiate cause reflective, reduce answer interference.
The embodiment of the present invention two as shown in Figure 2,3, the computer examination anti-cheating device of this band LED light
On the basis of embodiment one, upper cover plate, left side wall, right side wall break as front and back two sections, upper cover along same vertical plane
Plate leading portion is provided with the middle crack 7 making upper cover plate leading portion be fractured into two sections, left and right, middle crack two in center ofthe position
Side is respectively symmetrically and at least one side crack 8 is distributed, and crack, side is extended back and middle crack by upper cover plate leading edge
Intersecting, the crack 9 disconnected before and after upper cover plate is gradually widened to middle fractuer direction by left and right, and above-mentioned breaking part is the most logical
Cross flexible rubber to connect, interstitial for side cover plate can be erected during use and be clamped together to folded, reduce
Left side wall, the distance of right side wall forward edge, to adapt to various sizes of display.
The embodiment of the present invention three as shown in Figure 4, on the left of the computer examination anti-cheating device of this band LED light
Wall, the lower limb of right side wall are gradually risen by after forward direction, reserve bigger working place, head-shield bottom in bottom
The left and right sides is connected to expansion link 10, and expansion link lower end connects buttstrap 11, and expansion link is made up of two joints,
Wherein a joint can rotate relative to another joint for bending, can regulate the relative position of health and device.
The embodiment of the present invention four is as it is shown in figure 5, the computer examination anti-cheating device of this band LED light blocks
Cone cylinder and head-shield be can before and after the bellows-folded structure of stretching, figure is deployed condition, can stretch and be easy to people and enter
Entering and stand to leave and have no relations, the used time can not get up save space with folding storage, it is also possible to disassembles,
The examination personnel of different sitting height can also be adapted to simultaneously.
The upper cover plate of the computer examination anti-cheating device of this band LED light also can be provided with hole, it is simple to invigilator
Teacher, it is observed that the action of examinee, prevents the behavior that examinee practises fraud.
Relative to traditional hard baffle plate, the present invention's is higher for the closure between student, old for invigilator
Closure between teacher and student is lower, and supervisor can supervise the examination of student from the hole of upper cover plate, also
Can prevent student examinee from practising fraud from the action of the hands seeing student of bottom.This point is ordinary rigid baffle plate
Cannot accomplish.
Also can connect display lamp on upper cover plate or head-shield when the present invention implements, display lamp can make lamp bead or LED
Lamp, display lamp connects USB plug, and when examination, USB plug to be inserted on main frame by student
Corresponding USB interface, so corresponding display lamp will be bright.Supervisor finds that the display lamp of student knocks out,
Just USB plug is extracted by explanation student, and the USB flash disk of band privately of oneself is likely inserted in USB interface by student
Examination information is copied to above computer and practice fraud.
Multiple display lamp and USB plug can be set according to host USB port quantity during enforcement.Multiple display lamps
Can have multiple color, student has corrupt practice to facilitate supervisor to find.
Although can also be configured to shield USB interface by computer, but owing to school computer center is held concurrently simultaneously
Doing teaching computer lab and examination machine room, teaching computer lab student needs to practice in the data copy in USB flash disk to machine room
Practise, it is also desirable to upper machine operation is copied in USB flash disk by student.If arrived examination, every computer
All being configured to shield USB interface, the workload for computer room administrator is the biggest.
School computer center also serves as teaching computer lab and examination machine room simultaneously, and teaching computer lab requires that computer is put and presents opening
The form of formula, it is simple to discuss mutually between student and the upper machine of teacher instructs.If but as examination machine room,
Seek closure, prevent student from practising fraud mutually.If this teaching cannot be realized with traditional hard baffle plate and examines
Try dual-purpose this demand, the convenient dismounting of the present invention and storage, it is especially suitable for school computer center and uses.
It is only the specific embodiment of the invention in sum, but is not limited to embodiment, also can each technical characteristic weight
The more implementation of Combination nova, all without departing from the inventive concept, the equivalence done according to the application is repaiied
Decorations and prior art interpolation are accordingly to be regarded as the technology of the present invention category.
