Embodiment
Below by the description to embodiment, the shape of for example involved each component of embodiment of the invention, structure
Make, the mutual alignment between each several part and annexation, the effect of each several part and operation principle, manufacturing process and the side of operating with
Method etc., is described in further detail, completeer to help those skilled in the art to have inventive concept of the invention, technical scheme
Whole, accurate and deep understanding.
As shown in Figures 1 to 5, a kind of anti-cheating desk, including supporting plate 1, the both sides of supporting plate 1 are provided with groove, desk body
Top is provided with two pieces of shadow shields 2, and shadow shield 2 is rotatably arranged in groove, and shadow shield 2, which can be fixed on, is laid in supporting plate 1
On first position and the second place vertical with supporting plate 1.
The width of shadow shield 2 is equal to the half of the spacing between two grooves in supporting plate 1, can make two pieces of shadow shields 2
It when being in first position, can be bonded between two shadow shields 2, make the gap between two pieces of shadow shields 2 small as far as possible, to the greatest extent
Amount reduces the influence that the gap uses student the anti-cheating desk.
In a kind of preferred embodiment, the anti-cheating desk also includes connector 3, and every piece of shadow shield 2 passes through connection
Part 3 is rotatably connected with supporting plate 1.Connector 3 is made using metal material, and connector 3 is provided with vertical waist-shaped hole,
Between connector 3 and supporting plate 1 mode such as riveting or threaded connection can be used to be fixedly connected.As further changing for the present invention
Enter, the quantity of connector 3 is preferably four, and the both ends of every piece of shadow shield 2 are connected by connector 3 with shadow shield 2.Shading
The both ends of plate 2 are provided with symmetrical bearing pin 2b, and bearing pin 2b is movably installed into waist-shaped hole.When shadow shield 2 is in first
During position, bearing pin 2b is located at close to the 3rd position of waist-shaped hole upper end in waist-shaped hole, when shadow shield 2 is reversed in second
During position, shadow shield 2 moves down under gravity, and the end of shadow shield 2 contacts with the bottom of groove, and groove is to shading
Plate 2 plays a part of support, and now bearing pin 2b is located in waist-shaped hole close to the 4th position of waist-shaped hole lower end.This structure can be with
The effect of self-locking is played, prevents supporting plate 1 from overturning.
When shadow shield 2 is in the second place, student neglectful can encounter shadow shield 2 unavoidably in use, be
Prevent the shadow shield 2 in the second place from being overturn by external force, influence the use of student, it is necessary to increase shadow shield 2
Stability.Therefore, being provided with lockable mechanism between supporting plate 1 and shadow shield 2, lockable mechanism includes latch 4 and compression spring 5,
The first counterbore is provided with the groove of supporting plate 1, shadow shield 2 is provided with the second counterbore 2a, when shadow shield 2 is in the second place,
Second counterbore 2a is corresponding with the first counterbore position, and the end of supporting plate 1 is additionally provided with first through hole, and first through hole extends to first
Counterbore, latch 4 are provided with projection 4a, and compression spring 5 is installed in the first counterbore with latch 4, the both ends difference of compression spring 5
The bottom of the first counterbore and one end of latch 4 are connected to, the other end of latch 4 exposes from the first counterbore, and projection 4a is through the
One through hole exposes to the outside of supporting plate 1.When it is desired to be used, projection 4a is pushed down on, is made in the counterbore of retraction first of latch 4,
Shadow shield 2 is afterwards turned over to the second place, then unclamps projection 4a, under the elastic force effect of compression spring 5, latch 4 from first
Partly enter after being ejected in counterbore in the second counterbore 2a, so as to play the purpose for preventing that shadow shield 2 from overturning.
As the further improvement of present embodiment, in order to increase stability when shadow shield 2 is in the second place, work as screening
When tabula rasa 2 is in the second place, shadow shield 2 can be affixed towards the side of supporting plate 1 with groove towards the side of supporting plate 1
Close, and the end that bearing pin 2b is provided with shadow shield 2 is provided with reinforcement.
When the light of surrounding environment is poor, the opening of shadow shield 2 may can obstruct the light, and deteriorate the light ring of student
Border, the eye strain of student is easily caused, or even increase student suffers from the possibility of the ophthalmology diseases such as myopia.In order to solve this
Problem, LED 6 is installed on shadow shield 2, when the light environment of surrounding is poor, opens LED 6, you can optimize student's
Use environment.
The present invention devises turnover shadow shield 2 in supporting plate 1, it is daily attend class during, shadow shield 2 is in the
One position, the use same with traditional desk, during examination, shadow shield 2 is in the second place, can prevent left and right adjacent seat it
Between peep, there is good anti-cheating effect, in addition, when ambient light is poor, after shadow shield 2 is in the second place,
LED 6 is opened, improves the light environment on periphery, can be good at preventing eye disease.
