Embodiment 1
[0037]An anti-cheating desk, comprising a first support column 1, a support frame 2, a storage box 3, a first rotating shaft 4, a first movable plate 5, a clamping mechanism 6, a warning mechanism 7, a lifting mechanism 10 and a pulling mechanism 11, see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the number of the first support column 1 is two, a support frame 2 is welded between the upper part of the first support column 1, the middle of the top of the support frame 2 is rotatably provided with a storage box 3, and the front and rear sides of the bottom of the storage box 3 are left and right. Slotted holes are opened symmetrically, the upper left and right sides of the storage box 3 are rotatably provided with a first rotating shaft 4, the first rotating shaft 4 is provided with a first movable plate 5, and the front and rear sides of the outer side of the first mova...
Embodiment 2
[0044] On the basis of Embodiment 1, a fixing mechanism 8 is also included, and the fixing mechanism 8 includes a support rod 81 , a limit rod 82 and a third spring 83 , see figure 1 and Figure 7 As shown, the upper left and right sides of the support frame 2 are slidably provided with support rods 81, and the front and rear sides of the support rod 81 are welded with limit rods 82. The limit rods 82 can clamp the storage box 3, thereby fixing the storage box 3. , the limit rods 82 all pass through the top of the support frame 2 and contact the storage box 3, and there are third springs 83 between the front and rear sides of the top of the support rod 81 and the support frame 2, and the third springs 83 are wound around the same side. on the limit rod 82 .
[0045] When people rotate or reverse the storage box 3 by 180 degrees, the storage box 3 will squeeze the limit rod 82 to move downward, thereby driving the support rod 81 to move downward, and the third spring 83 is str...

Abstract
The invention relates to a desk, in particular to an anti-cheating desk. The invention aims to provide the anti-cheating desk which can give a prompt when people take and read data. The anti-cheating desk comprises first supporting columns, a supporting frame, a storage box, a first rotating shaft and the like, the number of the first supporting columns is at least two, the supporting frame is arranged between the upper portions of the first supporting columns, and the storage box used for storing examination related data is rotationally arranged in the middle of the top of the supporting frame; and first rotating shafts are rotationally arranged on the left and right sides of the upper part of the storage box. According to the invention, data related to an examination are put into the storage box, and the storage box is rotated by 180 degrees, so that when people take the data by rotating a second movable plate during the examination, the second movable block can impact a supporting plate to make a sound, and thus an invigilator can know that someone takes the data through the sound; therefore, cheating of people in examination can be prevented in time.
