Description

Technical Field

[0001] The invention relates to the field of teaching equipment, in particular to a movable and foldable examination anti-cheating device. Background Art

[0002] At present, in various examinations, candidates often cheat by peeking at adjacent examination papers or using wireless communication devices, which not only seriously affects the fairness and seriousness of the examination, but also poses a huge threat to educational equity. In order to effectively prevent cheating, educational institutions usually take a series of strict anti-cheating measures. For example, professionally trained invigilators are set up to ensure the maintenance of examination room discipline; at the same time, surveillance cameras are installed to monitor the examination room in all directions to identify and respond to potential cheating in a timely manner. These comprehensive preventive measures are aimed at creating a more fair and transparent examination environment, thereby protecting the legitimate rights and interests of each candidate and enhancing the overall credibility of the examination.

[0003] However, it is often difficult for invigilators to observe in real time when candidates peek at adjacent test papers, resulting in the inability to detect cheating in time and thus leaving no strong evidence. This covert cheating method poses great challenges to invigilators in the examination room, especially when there are a large number of candidates or the examination environment is complex. In addition, the distraction of the invigilator may allow some cheating behaviors to escape monitoring, thereby affecting the fairness of the examination. Therefore, manual supervision and monitoring by the invigilator alone is not enough to completely eliminate such behaviors. For this reason, those skilled in the art have proposed a movable and foldable anti-cheating device for examinations to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a movable and foldable anti-cheating device for examinations, which solves the problem of examinees peeking at adjacent examination papers. It is often difficult for invigilators to observe in real time, resulting in the inability to detect cheating behavior in time, thereby failing to leave strong evidence.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a movable foldable anti-cheating device for examinations, comprising a desk, wherein three mounting parts are arranged on the top of the desk, which are the basic components of the device, two sliders are arranged inside the mounting parts, four fixing components are arranged inside the mounting parts, which are used to fix the two sliders, and a snap assembly is arranged inside the slider, which is used to disassemble and assemble the support column, and two shielding cloths are fixedly connected to the adjacent sides of the support columns on the front and rear sides, and a folding assembly is arranged on the adjacent sides of the two shielding cloths, which is used to assist in folding and storing the two shielding cloths.

[0015] Working principle: First, place the front and rear mounting seats opposite to each other, then place the base on the mounting seats, and then install the mounting seats and the base on the desk through bolts;

[0016] Secondly, by rotating the handle on the slider in the first slide slot, the two pull ropes are driven to move toward the adjacent side, thereby driving the second limit block to move inward, thereby driving the clamping block to move with it, and then placing the support column inside the slider, thereby driving the second limit block to move outward through the elastic action of the second spring, thereby driving the clamping block to move with it into the inside of the clamping slot, so that the clamping block is engaged with the clamping slot, thereby fixing the support column;

[0017] Thirdly, by pulling the two sliders to move away from each other, the support column is driven to move, and the folded shielding cloth is driven to move with it, thereby driving multiple folding columns to move, and then driving the cross rods to extend horizontally through the connecting shaft, so that the shielding cloth can be extended to shield the adjacent table;

[0018] At the same time, through the movement of the slider, the slider will squeeze the protrusion to move inward, thereby driving the limit block 1 to move with it. After the slider moves to a suitable position, the elastic action of the spring 1 drives the limit block 1 to move outward, thereby driving the protrusion to move with it into the groove, so that the protrusion is engaged with the groove, and the slider is fixed;

[0019] Finally, by placing both ends of the shielding plate in the guide grooves of the adjacent supporting columns at the rear side, the examinees are prevented from observing the actions of the invigilators, thereby completing the installation of the entire device.

[0020] The present invention provides a movable and foldable anti-cheating device for examinations. It has the following beneficial effects:

The present invention can effectively block the sight between examinees through the installation of the device and the unfolding of the shielding cloth, protect the privacy of each examinee's test paper, reduce interference between each other, and allow the invigilator to focus more on the overall monitoring of the examination room without having to pay too much attention to the specific behavior of each examinee. This helps to improve monitoring efficiency and ensure the fairness of the examination environment.

[0022] 2. The present invention can limit the line of sight of examinees through the shielding cloth and the shielding board, reduce the possibility of adjacent examinees copying each other, and thus reduce the occurrence of cheating. After reducing visual interference, examinees can focus more on their own test papers, thereby improving the overall effect of the test. In addition, if cheating occurs, the invigilator can capture it in time through the one-way light-transmitting shielding board, and provide strong evidence support through monitoring to help maintain the fairness of the test.

[0023] 3. The present invention can conveniently fix the slider and disassemble the support column by setting the fixing component and the snap-fit ​​component, so that the installation and operation are relatively simple, the invigilator can deploy quickly, save time, improve the organization efficiency of the examination, and can adapt to different examination room environments and the number of candidates.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example:

[0036] Please refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 4 The embodiment of the present invention provides a movable and foldable anti-cheating device for examinations, including a desk 1. Three mounting members 2 are arranged on the top of the desk 1, which are the basic components of the device. The mounting member 2 includes two mounting seats 201. The two mounting seats 201 are respectively arranged on the front and rear sides of the desk 1. The adjacent sides of the two mounting seats 201 are detachably connected with a base 202, and a slide groove 203 is opened inside the base 202.

[0037] Specifically, the desk 1 is an examination tabletop, which is used for installing an anti-cheating device for examinations. There are two mounting seats 201, which are respectively installed on the front and rear sides of the desk 1. It has good durability and pressure resistance. The base 202 is set to be detachable, so that it can be easily removed when not needed, saving storage space. The design of the base must ensure that it is firmly connected to the mounting seat 201 and is easy to install and disassemble quickly. The slide groove 203 is located inside the base 202, so that the slider 3 can slide inside.

[0038] Please refer to the attached Figure 4 -Attached Figure 6 Two sliders 3 are arranged inside the mounting member 2, and the outside of the slider 3 is slidably connected to the inside of the slide groove 203. Four fixing components 4 are arranged inside the mounting member 2, which are used to fix the two sliders 3. The fixing component 4 includes a mounting groove 401, which is opened inside the base 202, and a spring 402 is arranged inside the mounting groove 401. The inside of the mounting groove 401 is slidably connected to a limiting block 403, one end of the spring 402 is fixedly connected to the outside of the limiting block 403, and the other end of the spring 402 is fixedly connected to the inner wall of the mounting groove 401, and a protrusion 404 is fixedly connected to the outside of the limiting block 403. A plurality of grooves 405 are arranged inside the slider 3, and the left and right sides of the slider 3 are provided with the grooves 405, and the outside of the protrusion 404 matches the inside of the groove 405.

[0039] Specifically, when the slider 3 slides in the slide groove 203, due to the matching between the slider 3 and the groove 405, the movement of the slider 3 will be constrained by the fixing component 4, and the spring 1 402 plays an important return role in the installation groove 401. When the slider 3 is pushed in the slide groove 203, the protrusion 404 is squeezed to compress the spring 1 402 and store energy. When the force stops, the spring 1 402 will quickly recover and push the limit block 1 403 back to the initial position, so that the protrusion 404 can also return to the preset initial state. The cooperation between the protrusion 404 and the groove 405 provides a mechanical locking effect to ensure that the slider 3 does not accidentally fall off or deviate during the movement, and the arc-shaped design of the outer part of the protrusion 404 allows the protrusion 404 to move stably when under pressure.

[0040] Please see attached Figure 4 , Attachment Figure 7 and attached Figure 8 A buckle assembly 6 is provided inside the slider 3, which is used to disassemble and assemble the support column 5. The outside of the support column 5 is slidably connected to the inside of the slider 3. The buckle assembly 6 includes two limit grooves 601, which are respectively opened on the left and right sides of the inside of the slider 3. The inside of the limit groove 601 is slidably connected to a limit block 603, one end of the limit block 603 is fixedly connected with a clamping block 604, and the other end of the limit block 603 is fixedly connected with a pull rope 606. The outside of the pull rope 606 is sleeved with a spring 602, one end of the spring 602 is fixedly connected to the outside of the limit block 603, and the other end of the spring 602 is fixedly connected to the inner wall of the limit groove 601. The adjacent side of the two pull ropes 606 is fixedly connected with a turning handle 607. Slots 605 are opened on the left and right sides of the inside of the support column 5, and the outside of the clamping block 604 matches the inside of the slot 605.

[0041] Specifically, the slider 3 is used as a connector of the support column 5, and a buckle assembly 6 is provided inside, which can flexibly disassemble and assemble the support column 5, and is slidably connected to the slider 3. The block 604 cooperates with the slot 605 to fix its stability in the slider 3. The spring 2 602 keeps the limit block 2 603 fastened under the action of the pull rope 606, so that the block 604 is firmly embedded in the slot 605, effectively preventing the support column 5 from accidentally falling off during use. The limit slot 601 is used to fix the limit block 2 603. The limit block 603 is limited so that it can move along the predetermined trajectory. The support column 5 can be fixed by matching the card block 604 with the card slot 605. The pull rope 606 can drive the limit block 603 to move. The pull rope 606 can be driven to move in the slider 3 by rotating the handle 607. The user can rotate the handle 607 and pull the pull rope 606 to make the limit block 603 slide in the limit slot 601, and the card block 604 will be released from the card slot 605.

[0042] Please see attached Figure 8 and attached Fig. 9 Two shielding cloths 7 are fixedly connected to the adjacent sides of the front and rear support columns 5, and a folding assembly 8 is provided on the adjacent sides of the two shielding cloths 7, which is used to assist the two shielding cloths 7 in folding and storage. The folding assembly 8 includes a plurality of folding columns 801, and the plurality of folding columns 801 are fixedly connected to the adjacent sides of the two shielding cloths 7 at equal intervals. A cross rod 803 is provided on the adjacent sides of the plurality of folding columns 801, and the plurality of cross rods 803 are connected through upper and lower connecting shafts 804. The outer portion of the upper connecting shaft 804 is rotatably connected to the inside of the folding column 801, and the outer portion of the lower connecting shaft 804 is slidably connected to the inside of the slide groove 802.

[0043] Specifically, a plurality of folding columns 801 are equidistantly fixedly connected to adjacent sides of two shielding cloths 7 to provide support and folding functions. A cross rod 803 is arranged on adjacent sides of the folding column 801 to enhance the stability and flexibility of the structure. The connecting shaft 804 is divided into an upper connecting shaft 804 and a lower connecting shaft 804 to connect the cross rod 803 and the folding column 801 so that the cross rod 803 can move flexibly. The second slide groove 802 provides a sliding path for the lower connecting shaft 804 to ensure smooth operation of the folding assembly. When the shielding cloth 7 needs to be stored, the folding column 801 is pulled and the cross rod 803 rotates accordingly. The shielding cloth is folded by rotating the upper connecting shaft 804, and the lower connecting shaft 804 slides in the second slide groove 802 to cooperate with the movement of the folding column, making the entire folding process smoother and more efficient.

[0044] Please refer to the attached Figure 1 , Attachment Figure 3 and attached Figure 4 A guide groove 9 is provided on both sides of the rear support column 5, and a shielding plate 10 is slidably connected to the inside of the guide groove 9. The shielding plate 10 is a one-way light-transmitting plate, and the outside cannot be seen from the inside.

[0045] Specifically, the inner surface of the guide groove 9 is finely processed to reduce friction and ensure smooth sliding of the baffle 10, and a special one-way light-transmitting material is used to ensure that the user inside cannot see the outside, so that the examinee cannot observe the invigilator, and the invigilator can monitor the examinee and detect cheating behavior in time.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
