Abstract
The invention belongs to the field of classroom examination tools, and in particular relates to an anti-cheating device for general examinations. The anti-cheating device mainly solves the problems that examinees cheat with mobile phones and the cheating phenomenon is serious during examination paper submitted in examination, also guarantees the consistency of the answering time of the examinees and supplies convenience to teachers for sending and receiving examination papers. The anti-cheating device mainly comprises an examination paper box (1), a mobile phone box (4), a baffle plate (2), a ratchet wheel (5), a pawl (9), a left stop piece (6), a right stop piece (12), a cam (7), a main shaft (8), a shifting fork (10), a button (11), a special key and a mechanical timer connected with the main shaft. Due to the pure mechanical structure, precise timing is realized; the two current most general cheating behaviors are effectively prevented; furthermore, the anti-cheating device is simple in structure, high in reliability and low in cost, and has a wide practical prospect.
Description
Technical field:
The invention belongs to school examination's apparatus, particularly a kind ofly utilize frame for movement that nation's civil ordinary examination table is had to prevent that examinee from practising fraud and the anti-cheating device that guarantees that each examinee's test time is consistent.
Background technology:
Statistics shows, since 1988, treating in exam phenomenon has the trend of obviously spreading unchecked.Not only number is more, and cribber's level is also improving.In school control, we are not difficult to find, student examination cheating is ubiquity not only, and means are more and more diversified, and is tending towards modernization.Along with popularizing of mobile phone, mobile phone cheating becomes main flow cheating tool gradually.
Yet nowadays our main anti-cheating mode still relies on teacher's invigilator, advanced communication tool emerges in an endless stream, and only relies on teacher's the very difficult use that guarantees the electronic equipments such as fairness, especially mobile phone of examination of invigilator, has strengthened especially the difficulty of taking precautions against.Simultaneously when transmitting-receiving paper, Time Of Release asynchronous, the chaotic scene occurring while receiving paper brings great convenience to cheating especially.At present anti-cheating device is on the market because poor effect or the more high reason of cost are difficult to really come into operation.
At present country is increasing to classmate's learning rate of good character and fine scholarship, the fair and just property of link if we can not guarantee to take an examination, and the granting of scholarship is just difficult to reach the object of encouraging student of good character and fine scholarship.
Summary of the invention:
Based on above-mentioned situation, invented a kind of simple in structure, good reliability, the nation's civil ordinary examination anti-cheating device of successful.
Basic structure of the present invention is comprised of paper box (1), box of mobile telephone (4), baffle plate (2), guide rail (3), ratchet (5), ratchet (9), left block (6), right block (12), cam (7), main shaft (8), shift fork (10), button (11), private key and the mechanical timer that is connected with main shaft.Wherein baffle plate (2) is positioned at guide rail (3).
Baffle plate (2) is positioned at the sealing part of box of mobile telephone (4) and paper box (1), and when it is positioned at a side, the box of a corresponding side is closed, and opposite side is opened, and vice versa.
Main shaft (8), ratchet (5) are connected with timer, and at the uniform velocity rotation in time, can, by timing key rotary main shaft (8), to timer regularly, can drive main shaft (8) and ratchet (5) rotation when timer rotates in time.
Button (11) rear side has a push rod, when key B side is inserted, can be promoted by push rod on the key, and by and right block (12) between connecting axle promote right block (12), make it remove self-locking state.
Ratchet (9) is fixed by spring, when contacting with the non-whole number of teeth of ratchet (5), can be back into whole number of teeth place by elastic force, thereby realize accurate timing.
It is upper that cam (7) is enclosed within main shaft (8), and with main shaft (8) rotation, when main shaft (8) is positioned at initial position, cam (7) can make left block (6) jack-up rise on its right side, and left side declines.
Left and right block all can stop that baffle plate (2) is mobile with ledge, at left block (6) during by cam (7) jack-up, its ledge moves down, coordinate with the upper breach of baffle plate (2), baffle plate (2) cannot be moved to the right, after cam (7) turns an angle, on left block (6) ledge, move, baffle plate (2) returns to and can move freely state.Right block (12) is positioned at self-locking position when button (11) is pressed, and stops baffle plate (2) to be moved to the left simultaneously, and when its self-locking state is removed, plate washer (2) can freely-movable.
Beneficial effect of the present invention is:
1, whole device is pure frame for movement, can turn round voluntarily, without external power supply, easy for installation, good reliability, and simple in structure, with low cost;
2, strictly controlled examination process middle school student's intervention, all operations has irreversibility, can only down carry out step by step according to examination flow process, and key component all needs to use private key operation, has prevented the cheating that examination middle school student oneself operate;
3, this product meets student's demand, has guaranteed fairness and the fairness of examination, has wide range of applications, and there is no in the market similar products appearance, has good market prospects.

The specific embodiment
The present invention is a kind of auxiliary equipment of examination desk, can strictly control taking out and putting back to of mobile phone and paper for when examination different time sections, and guaranteed the uniformity of each examinee's test time, the fairness that can fully realize examination, below in conjunction with the drawings and specific embodiments, the present invention will be further described.
1, before examination, teacher puts into paper box (1) by paper, subsequently baffle plate (2) is moved on to paper box (1) one end, is closed.Then with key, insert keyhole, now button (11) upper ejector pin ejects, and right block (12), in self-locking state, blocks baffle plate (2), and it cannot be moved right.Teacher rotates key, by ratchet (5) ratchet (9) accurate timing.
2, examinee enters examination hall, and mobile phone is put into box of mobile telephone (4).After examination starts, student presses the button (11), and right block (12) is removed self-locking state, and student can move right baffle plate (2).Take out paper, start to answer.
While 3, taking an examination, main shaft (8) has rotated an angle, cam (7) is separated with left block (6), left block (6) moves down on right side under the effect of gravity, left side perk, in running order, block baffle plate (2), it cannot be moved to the left, and examinee cannot take out mobile phone.
When 4, the test time is used up, main shaft (8) rotates go back to the position starting again, the baffle plate (2) in left side is by jack-up, left block (6) is in off working state, examinee need to put into paper paper box (1), and baffle plate (2) is moved to left side, opens box of mobile telephone (4) when closing paper box (1), take out mobile phone, leave examination hall.
If 5, run into emergency case or student hands in an examination paper in advance in examination, supervisor can reset main shaft (8) by key, and cam (7) is again by left block (6) jack-up, baffle plate (2) motion that affranchises, student puts into paper, takes out mobile phone, leaves examination hall.
6, examination finishes, and all examinee leaves behind examination hall, and teacher opens paper box (1), takes out paper.
