Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 7, a desk for preventing cheating comprises a desk top 1 and four desk legs 2 which have the same structure and are arranged at the lower end of the desk top 1, accommodating grooves 3 are formed in two ends of the desk top 1, a abdicating groove 4 is formed in the side surface of the desk top 1, an object accommodating groove 7 is formed in the desk top 1, a baffle mechanism 5 for preventing cheating is arranged in the object accommodating groove 7, and a hand-operated driving mechanism 6 for driving the baffle mechanism 5 to move up and down in the accommodating groove 3 is further arranged on the side, provided with the abdicating groove 4, of the desk top 1.

In this embodiment, baffle mechanism 5 includes that two structure symmetries and material are the baffle 8 of PP, 8 sliding connection of baffle are in accomodating groove 3, two 8 lower extremes of baffle be equipped with connecting rod 9, connecting rod 9 is arranged in and is put thing groove 7, 9 one end of connecting rod is equipped with joint piece 10, joint piece 10 is connected hand actuating mechanism 6 and is followed the interior up-and-down motion of groove 4 of stepping down.

In this embodiment, 8 lower extremes of baffle are equipped with draw-in groove 11, be equipped with on the connecting rod 9 with the sand grip 12 of draw-in groove 11 joint.

In this embodiment, hand actuating mechanism 6 includes that two are installed in the running roller 13 on one side of the groove 4 of stepping down, running roller 13 rotates and connects in mesa 1 side, and two running rollers 13 have cup jointed belt 14 outward, one side of joint piece 10 joint belt 14 is fastened with the screw, wherein the running roller 13 outside installation handle 15 of lower extreme.

In this embodiment, the hand actuating mechanism 6 is equipped with the safety cover 16 outward, the safety cover 16 passes through the screw mounting in mesa 1 side, set up handle hole 17 of stepping down and the spacing post 18 of installation on the safety cover 16, be equipped with the spacing hole 19 and the spacing hole two 20 that the size is the same on handle 15 and the spacing post 18 respectively, be equipped with spacing bolt 21 in the spacing hole two 20.

The working process and principle are as follows: when the examination room is used in an examination occasion, when the staff in charge of the examination room arranges seat examination numbers and the like, the staff can shake the handle 15 by hand to enable the roller 13 and the belt 14 to move, so that the clamping block 10 connected on the belt 14 moves upwards along the abdicating groove 4 to drive the connecting rod 9 to move, the baffle plate 8 is connected on the connecting rod 9 to enable the baffle plate 8 to move upwards along the accommodating groove 3, when the baffle plate 8 rises to a required height, the limiting bolt 21 is placed into the first limiting hole 19 and the second limiting hole 20 to fix the handle, the baffle plate 8 stops moving, the cheating of examinees who think from the left or the right during examination can be prevented, and the baffle plate 8 is clamped on the convex strip 12 on the connecting rod 9, so that the phenomenon that the examinees in the seat touch the paper board when leaving the seat to touch the seat to cause the sliding of the paper board to influence the examinees still in the examination is reduced, after the examination is finished, the staff in the examination room pulls out the first limiting bolt 21 to pull the first limiting hole, the handle 15 is shaken, and the sliding plate 8 is reset and accommodated in the accommodating groove 3, so that the damage or the influence on the normal use is prevented.

The utility model discloses simple structure, 8 baffle through setting up 6 drive baffle mechanisms 5 of hand actuating mechanism are along accomodating 3 interior up-and-down motion in the groove to when making the examination occasion use, can prevent that examinee from looking into the cheating when taking an examination about a left side, it leads to the cardboard to slide to influence still the examinee in the examination to bump the cardboard when having examined to leave the seat to have reduced the examinee that the seat leaned on the lining, after the examination, slide 8 resets to be received and is included in accomodating groove 3, prevent damage or influence normal use, the practicality is high.
