Specific embodiment
The embodiment of the present invention one is as shown in Figure 1, the computer examination device for preventing USB flash disk from practicing fraud is equipped with and blocks 1 He of cone cylinder
Head-shield 2 blocks cone cylinder and connects equipped with left side wall 3, right side wall 4 and upper cover plate 5, the top edge of left side wall and the left side edge of upper cover plate
Connect, the connection of the right side edge of right side wall top edge and upper cover plate, left side wall, right side wall forward edge be connected with clip 12, this
Embodiment clip is the elastic clip with side plate one, can also be clamped using individual clip, the clip of two sides is clamped in respectively
On 6 left and right sides frame of display, upper cover plate forward edge is ridden on the upside of display on frame, left side wall, right side wall back side edge
The distance of edge is greater than the width of face and is less than the distance of left side wall, right side wall forward edge；Head-shield is respectively and after left side wall
The cover plate extended to head part two sides and top that side edge, right side wall posterior edges, upper cover plate posterior edges are connected, cover plate
It can be surrounded for straight panel, can also be curved slab plate and surround, the present embodiment surrounds for curved slab, as long as sheltering from the two sides of head.
In the use of the present invention, the present apparatus can be fixed on the frame of display two sides by clip, it can be fine using side plate
Ground blocks the plagiarism of adjacent seat examination personnel, and cover plate can also play the role of blocking the sight to two sides simultaneously, but also can keep away
Exempt from reflective caused by light irradiation, reduction answer interference.
As shown in Figure 2,3, this prevents computer examination device of USB flash disk malpractices in the base of embodiment one to the embodiment of the present invention two
On plinth, upper cover plate, left side wall, right side wall break along same vertical plane as two sections of front and back, and upper cover plate leading portion is equipped in center ofthe position
Upper cover plate leading portion is set to be fractured into the middle crack 7 of two sections of left and right, at least one side crack 8 is respectively symmetrically distributed in middle crack two sides,
Side crack is extended back by upper cover plate leading edge intersects with middle crack, and the crack 9 disconnected before and after upper cover plate is from controlling to middle crack
Direction is gradually widened, and above-mentioned breaking part is connected by flexible rubber, can erect by the interstitial cover board in side when use
It is clamped together to folded, reduces the distance of left side wall, right side wall forward edge, to adapt to various sizes of display.
The embodiment of the present invention three is as shown in figure 4, the computer examination device left side wall for preventing USB flash disk from practicing fraud, right side wall
Lower edge gradually rises from the front to the back, and bigger operating space is reserved in lower part, is connected separately with and stretches at left and right sides of head-shield lower part
Contracting bar 10, telescopic rod lower end are connected with buttstrap 11, and telescopic rod is made of two sections, wherein a section is that bending can relatively another section rotation
Turn, the relative position of adjustable body and device.
The embodiment of the present invention four is as shown in figure 5, the computer examination device for preventing USB flash disk from practicing fraud blocks cone cylinder and head-shield is
Can the bellows-folded structure that stretches of front and back, be unfolded state in figure, can stretch to enter convenient for people and stand and leave and have no relations,
It can get up save space with folding storage when not used, can also disassemble, while also be adapted to the tester of different sitting heights
Member.
The upper cover plate of the computer examination device for preventing USB flash disk from practicing fraud can also be equipped with hole, can observe convenient for supervisor
To the movement of examinee, the behavior for preventing examinee from practising fraud.
It is of the invention higher for the closure between student relative to traditional hard baffle, for supervisor with
Closure between student is lower, and supervisor can supervise the examination of student from the hole of upper cover plate, can also be from bottom
The movement for seeing the hand of student prevents student examinee from practising fraud.This point is that ordinary rigid baffle can not be accomplished.
The present invention can also connect indicator light when implementing on upper cover plate or head-shield, and indicator light can make lamp bead or LED light, refer to
Show that lamp is connected with USB plug, when examination, USB plug is inserted into the corresponding USB interface on main frame by student, this
The corresponding indicator light of sample will be bright.Supervisor has found that the indicator light of student knocks out, and just illustrates that student extracts USB plug,
Student is possible to be inserted into USB interface to copy to examination information by the USB flash disk of band privately of oneself to practice fraud above computer.
Multiple indicator lights and USB plug can be arranged according to host USB port quantity when implementation.Multiple indicator lights can have
Multiple color facilitates supervisor to find that student has corrupt practice.
Although shielding USB interface can also be configured to by computer, since school computer center also serves as religion
Computer room and examination computer room are learned, teaching computer lab student needs to do the exercises the data copy in USB flash disk into computer room, it is also desirable to student
Upper machine operation is copied in USB flash disk.If arrived examination, every computer all to be configured to shielding USB interface,
Workload for computer room administrator is very big.
School computer center also serve as teaching computer lab and examination computer room, teaching computer lab require computer put present it is open
Form, convenient for being discussed mutually between student and the upper machine guidance of teacher.But closure is required if as examination computer room, it prevents
Student practises fraud mutually.It cannot achieve this teaching and dual-purpose this demand of taking an examination, this hair if it is with traditional hard baffle
Bright easy to disassemble and storage is very suitable to school computer center use.
It is only in summary the specific embodiment of the invention, but is not limited to embodiment, it can also each technical characteristic group again
Close more implementations, it is all without departing from the inventive concept, the equivalent modification and the prior art done according to the application
Addition is accordingly to be regarded as the technology of the present invention scope.
