Technical Field

[0001] This application relates to the field of teaching desk technology, specifically a teaching and examination integrated desk. Background Technology

[0002] Currently, some schools use a face-to-face desk arrangement, which facilitates group discussions and project collaborations. Students can communicate directly, share ideas, divide tasks, and work together to complete learning assignments. For example, when conducting group research projects, students can communicate quickly, improving collaboration efficiency.

[0003] However, during exams, because these desks are designed to face each other, students can easily see each other's answers on the exam paper. The desks are not convenient to use in both teaching and exam scenarios at the same time, have low versatility, and are not conducive to the fairness of the exam. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this application is to provide a teaching and examination integrated desk that can facilitate students' learning and discussion during teaching, and can also prevent students on both sides from copying the answers of the other side during examinations, thereby improving the versatility of the desk.

[0025] The technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] Please refer to Figure 1-Figure 4 This embodiment provides a teaching and examination integrated desk, including two desk units 1 and a mounting box 2 installed between the two desk units 1. A screen opening 21 is provided in the middle of the mounting box 2. An anti-peeping mechanism 3 is installed inside the mounting box 2 to separate the two desk units 1. Specifically, the anti-peeping mechanism 3 includes a roller 31 rotatably connected inside the mounting box 2. A screen 32 is wound around the outside of the roller 31. The screen 32 can extend out of the mounting box 2 from the screen opening 21. An adjustment component 33 is also installed inside the mounting box 2, which controls the screen 32 to extend vertically out of the mounting box 2 or to retract the screen 32 extending out of the mounting box 2 back into the mounting box 2. It should be noted that the mounting box 2 serves two purposes: firstly, it provides installation space for the anti-peeping mechanism 3; secondly, it ensures a more stable connection between the two desk units 1, improving the overall integrity of the desk.

[0027] Furthermore, refer to Figure 3 and Figure 4 The adjusting component 33 includes slide bars 331 symmetrically slidably connected to both sides of the mounting box 2; a connecting plate 332 is installed between the tops of the two slide bars 331, and the outermost edge of the curtain 32 is fixed to the connecting plate 332. The connecting plate 332 ensures a smoother installation of the curtain 32 and allows the curtain 32 to be pulled as a whole from its outermost edge, ensuring the stability of the curtain 32's extension; a rack 333 is fixedly connected to the side of the slide bars 331, and a drive mechanism is rotatably connected to both sides of the mounting box 2. A drive shaft 334 is provided, and an adjusting gear 335 that meshes with a rack 333 is fixedly connected to the drive shaft 334. A dual-axis motor 336 for driving the drive shaft 334 to rotate is installed in the mounting box 2. An adjusting rod 337 is also rotatably connected in the mounting box 2, and a torsion spring 338 is wrapped around the outer circumference of the adjusting rod 337. One end of the torsion spring 338 is fixedly connected to the adjusting rod 337, and the other end is fixedly connected to the inner wall of the mounting box 2. The adjusting rod 337 and the roller 31 are transmitted through a transmission gear set 339.

[0028] Continue to refer to Figure 3 and Figure 4 A worm gear 3341 is fixedly connected to the drive shaft 334, and a worm 3361 that meshes with the worm gear 3341 is fixedly connected to the shaft end of the dual-shaft motor 336.

[0029] It should be noted that the dual-axis motor 336 should be connected to a power source and a switch should be set to control the operation of the dual-axis motor 336, which is known to those skilled in the art; the switch controls the dual-axis motor 336 to rotate forward and backward, thereby controlling the state of the curtain 32.

[0030] The following is a further explanation based on specific usage scenarios. During normal class time, to facilitate communication and discussion between students on both sides of the desk, the screen 32 of the anti-peeping mechanism 3 is fully retracted into the mounting box 2. When an exam is required, the dual-axis motor 336 is started, which drives the drive shaft 334 to rotate through the transmission of the worm gear 3361 and worm wheel 3341. By adjusting the cooperation of the gear 335 and rack 333, the slider 331 is controlled to rise, which in turn drives the connecting plate 332 to rise synchronously, thereby pulling the screen 32 and causing the screen 32 to rise, thus separating the two desk units and preventing students on both sides of the screen 32 from copying answers from each other. It should be noted that during the ascent of the curtain 32, the roller 31 rotates as the curtain 32 is pulled, which in turn causes the adjusting rod 337 to rotate under the drive of the transmission gear set 339, further deforming the torsion spring 338. The purpose of using the worm gear 3341 and worm 3361 is not only for the transmission between the dual-axis motor 336 and the drive shaft 334, but also to ensure that the slider 331 will not descend due to the deformation of the torsion spring 338 by utilizing the self-locking property of the worm gear 3341 and worm 3361 transmission, thus ensuring the stability of the curtain 32 after it is extended.

[0031] After the exam, the dual-axis motor 336 is reversed by the switch, which in turn drives the slide bar 331 to descend, causing the outermost end of the curtain 32 to slowly descend. Under the action of the torsion spring 338, the scroll 31 rotates, continuously winding the curtain 32 onto the scroll 31.

[0032] Overall, by installing a box 2 between two desk units and setting an anti-peeping mechanism 3 inside the box 2, the screen 32 is completely rolled up inside the box 2 during teaching using the adjustment component 33. During the exam, the screen 32 is raised vertically from the exit 21 using the adjustment component 33, thus separating the two desk units. This avoids the problem of students on both sides of the screen 32 copying from each other, improving the versatility of the desks and enhancing the fairness of the exam.

[0033] Reference Figure 1-Figure 3 A hidden groove 22 that matches the size of the connecting plate 332 is provided on the top surface of the mounting box 2.

[0034] Depending on the specific usage scenario, the hidden slot 22 allows the top surface of the connecting plate 332 to remain flat after the curtain 32 retracts into the mounting box 2, thus making the desk surface relatively flat.

[0035] Reference Figure 1 or Figure 2 The bottom of the mounting box 2 is fixedly connected to a U-shaped support leg 4. The installation of the U-shaped support leg 4 can further ensure the overall installation stability of the mounting box 2 and the privacy mechanism 3, and can also further increase the stability of the two table units 1.

[0036] Reference Figure 3 and Figure 4 To reduce friction and make the extension and retraction of the curtain 32 smoother, a guide roller 5 is rotatably connected to the mounting box 2 at the bottom of the curtain exit 21. The curtain 32 passes through the guide roller 5 from the roll 31 and then vertically through the curtain exit 21 tangentially along the guide roller 5. This prevents the curtain 32 from sliding and rubbing against the corners of the curtain exit 21 when it is rolled up or unrolled. In this way, the guide roller 5 can reduce the wear on the curtain 32 during extension and retraction and also make the opening and closing of the curtain 32 smoother.

[0037] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this application.
