Description

Technical Field

[0001] This utility model relates to the field of teaching aids technology, specifically a rotating role assignment device for English situational dialogue practice. Background Technology

[0002] In English teaching, situational dialogue practice is an important way to improve learners' oral expression and language application skills. Appropriate role allocation is a key element in ensuring the smooth implementation of situational dialogue practice and enhancing its effectiveness. Currently, role assignment methods in English situational dialogue exercises are relatively traditional, commonly including teacher-assigned assignment, learner-selected assignment, and random assignment. Teacher-assigned assignment is heavily influenced by the teacher's subjective factors, making it difficult to guarantee fairness and randomness, and can easily lead to dependency among some learners, reducing their initiative. Learner-selected assignment often results in learners choosing familiar or simple roles, leading to an uneven distribution and failing to fully develop learners' ability to handle different scenarios and roles. While random assignment ensures some degree of randomness, it usually requires preparing drawing slips, making it cumbersome. In multi-person exercises, the drawing process is time-consuming and inefficient, lacking interactivity and failing to create a lively practice atmosphere, thus hindering learners' enthusiasm. In view of the above, this application is hereby submitted. Utility Model Content

[0003] The purpose of this invention is to provide a rotating role assignment device for English situational dialogue practice, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides a rotating role assignment device for English situational dialogue practice, including a base plate, a vertical plate mounted on the top surface of the base plate, a bushing rotatably mounted on the vertical plate, a turntable coaxial with the bushing mounted on the outer wall of the bushing, a plurality of label pasting grooves for pasting role labels on the outer surface of the turntable, and a fixed shaft rotatably mounted inside the bushing, one end of the fixed shaft being fixed to the vertical plate, and the other end of the fixed shaft extending to the front of the turntable and connected to an indicator needle.

[0005] Furthermore, a first connecting rod is slidably mounted on the front side of the upright plate, and a brake plate is connected to the top of the first connecting rod. A driving member is provided on the base plate to push the first connecting rod upward. Under the drive of the driving member, the first connecting rod slides upward so that the brake plate fits against the outer wall of the bushing, thereby locking the rotation of the turntable.

[0006] Furthermore, the driving component includes a support mounted on the top surface of the base plate, on which a second connecting rod is rotatably mounted. The front end of the second connecting rod is hinged to the bottom end of the first connecting rod, and the rear end of the second connecting rod is connected to a pedal.

[0007] Furthermore, a return spring is installed on the bottom surface of the pedal, and the bottom end of the return spring is connected to the top surface of the base plate. The initial elastic force of the return spring pushes the pedal to move upward.

[0008] Furthermore, the brake plate has an arc-shaped structure, and a rubber pad is installed on the inner arc surface of the brake plate.

[0009] Furthermore, a limiting groove extending along its length is provided on the first connecting rod, and a limiting post is fixedly installed on the upright plate, the limiting post being inserted into the limiting groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides efficient support for the initial process of role assignment through a turntable, label pasting slot, and bushing: Role information preparation is completed simply by pasting the corresponding role label for the English situational dialogue directly onto the label pasting slot on the outer surface of the turntable, eliminating the need for pre-cutting, writing, and folding paper strips as required by traditional lotteries, thus saving tedious material preparation and organization steps. When starting role assignment, simply push the turntable manually. The coaxial fixed relationship between the turntable and the bushing causes the bushing to rotate around the upright plate, allowing the role labels to be dynamically displayed synchronously with the turntable. This simplifies the startup process, eliminating the need for teachers to repeatedly manually assign roles or for learners to take turns selecting, and is especially suitable for the need for frequently changing dialogue scenarios in the classroom, reducing the time spent on initial operations.

[0011] 2. This utility model achieves efficient positioning through the coordinated operation of the pedal, second link, first link, brake plate, and automatic reset structure: When stopping, the user only needs to step on the pedal, which, through the linkage of the second link and the first link, pushes the brake plate to engage and lock with the bushing, quickly stopping the turntable rotation; after releasing the pedal, the reset spring automatically drives the pedal, link, and brake plate to reset, eliminating the need for manual adjustment of component positions. This allows for quick operation by a single person, and in multi-person scenarios, the result can be determined by one person stopping the turntable while everyone observes the indicator needle pointing to the role identifier, avoiding the time-consuming problem of multiple people taking turns drawing and waiting in traditional lotteries, thus improving the smoothness of the teaching process.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 This utility model provides a technical solution: a rotating role assignment device for English situational dialogue practice, including a base plate 1, a vertical plate 2 mounted on the top surface of the base plate 1, a bushing 3 rotatably mounted on the vertical plate 2, a turntable 4 coaxial with the bushing 3 mounted on the outer wall of the bushing 3, a plurality of label pasting grooves 5 for pasting role labels on the outer surface of the turntable 4, and a fixed shaft 6 rotatably mounted inside the bushing 3, one end of the fixed shaft 6 being fixed to the vertical plate 2, and the other end of the fixed shaft 6 extending to the front of the turntable 4 and connected to an indicator needle 7.

[0016] Specifically, the base plate 1 serves as the supporting foundation of the device, providing a stable vertical mounting reference for the upright plate 2 and ensuring the assembly accuracy of subsequent components; the bushing 3 is rotatably mounted on the upright plate 2, and its outer wall is coaxially fixed with the turntable 4, forming a transmission relationship in which the bushing drives the turntable to rotate synchronously; when the user pushes the turntable 4, the turntable 4 can drive the bushing 3 to rotate freely around the upright plate 2; multiple label pasting slots 5 are opened on the outer surface of the turntable 4 to fix the role labels of different English dialogue scenarios, preventing the labels from shifting when the turntable rotates and ensuring that the role information is clear; the fixed shaft 6 is rotatably mounted inside the bushing 3, with one end fixed to the upright plate 2 and the other end extending to the front of the turntable 4 and connected to the indicator needle 7; when the turntable 4 drives the bushing 3 to rotate, the fixed shaft 6 and the indicator needle 7 remain stationary, forming a contrast structure between dynamic role labels and static indicators, and ultimately the indicator needle 7... The assigned role is determined by the role identifier. Compared with teacher assignment and self-selection, random role assignment is achieved through the mechanical structure of a rotating turntable and a fixed pointer. This completely avoids interference from subjective factors, ensures fairness in the assignment, and meets the requirement for randomness in the background technology.

[0017] As a technical optimization of this utility model, a first connecting rod 8 is slidably installed on the front side of the upright plate 2, and a brake plate 9 is connected to the top of the first connecting rod 8. A driving member is provided on the bottom plate 1 to push the first connecting rod 8 to slide upward. Under the drive of the driving member, the first connecting rod 8 slides upward so that the brake plate 9 fits against the outer wall of the bushing 3, thereby locking the rotation of the turntable 4.

[0018] Specifically, in traditional lottery allocation, the result depends entirely on the "moment of drawing" and the process cannot be controlled; however, this structure uses a brake plate to lock the bushing, which can actively stop the turntable when it rotates to a suitable speed. This retains randomness while avoiding excessive waiting time caused by excessive rotation of the turntable due to inertia, thus solving the problem of long lottery process in the background technology.

[0019] As a technical optimization of this utility model, the driving component includes a support 13 mounted on the top surface of the base plate 1, a second connecting rod 12 rotatably mounted on the support 13, the front end of the second connecting rod 12 being hinged to the bottom end of the first connecting rod 8, and a pedal 14 being connected to the rear end of the second connecting rod 12.

[0020] Specifically, it adopts a pedal-driven system, allowing users to control the brake with their feet while simultaneously using their hands to push the turntable or observe the character markers, making operation more convenient. Compared to the single operation of folding and drawing slips of paper in the lottery, the coordinated use of multiple parts enhances the user experience.

[0021] As a technical optimization of this utility model, a return spring 15 is installed on the bottom surface of the pedal 14. The bottom end of the return spring 15 is connected to the top surface of the base plate 1. Under the initial elastic force of the return spring 15, the pedal 14 is pushed upward.

[0022] Specifically, the return spring 15 is installed between the bottom surface of the pedal 14 and the top surface of the base plate 1. In the initial state, it is in a naturally extended state, and its elastic force pushes the pedal 14 upward, so that the pedal maintains the initial position of upward displacement.

[0023] As a technical optimization of this utility model, the brake plate 9 is an arc-shaped plate structure, and a rubber pad is installed on the inner arc surface of the brake plate 9.

[0024] Specifically, the rubber pad installed on the inner arc surface of the brake plate 9 has a high coefficient of friction, which can significantly improve the friction with the outer wall of the bushing 3 compared to metal or plastic materials; under the same pedaling force, it can stop the bushing from rotating more quickly and improve braking efficiency.

[0025] As a technical optimization of this utility model, a limiting groove 10 extending along its length is provided on the first connecting rod 8, and a limiting post 11 is fixedly installed on the upright plate 2, with the limiting post 11 inserted into the inside of the limiting groove 10.

[0026] Specifically, this avoids misalignment between the brake plate 9 and the bushing 3 caused by linkage offset, ensuring precise locking and stopping with each braking action, improving the accuracy of role allocation results, and solving the problem that results are easily affected by operation in traditional methods.

[0027] Before engaging in English situational dialogue practice, users need to create corresponding character labels based on the scenario requirements of the exercise, and then affix these character labels one by one into the multiple label-attaching slots 5 on the outer surface of the turntable 4. During this process, the label-attaching slots 5 can position and fix the character labels, preventing them from shifting or falling off when the turntable rotates, ensuring that the character information is clearly identifiable. In the initial state, the pedal 14 is kept in an upward displacement state under the initial elastic force of the return spring 15. At this time, the rear end of the second link 12 is lifted with the pedal 14, and the front end is tilted downward. Through the hinge relationship, the first link 8 is pulled to slide downward along the vertical plate 2, so that the brake plate 9 at the top of the first link 8 is separated from the outer wall of the bushing 3, and the bushing 3 is in a state of free rotation. When a user needs to initiate the role assignment process, they push the turntable 4 by hand. The turntable 4 causes the bushing 3 to rotate around the vertical plate 2 and the fixed shaft 6. At this time, the role identification sticker on the turntable 4 moves in a circular motion in sync with the turntable, while the indicator needle 7 at the front end of the fixed shaft 6 remains stationary, creating a visual contrast between the dynamic role identification and the static indicator, providing a basis for the subsequent random role determination. When it is necessary to stop, step down on the pedal 14 with your foot. The pedal 14 moves downward against the elastic force of the return spring 15, causing the rear end of the second link 12 to rotate downward around the support 13, and the front end of the second link 12 to rise upward. Since the front end of the second link 12 is hinged to the bottom end of the first link 8, when the front end rises, it pushes the first link 8 to slide upward along the vertical plate 2. During this process, the limiting groove 10 on the first connecting rod 8 and the limiting post 11 fixed on the vertical plate 2 form a sliding fit. The limiting post 11 slides along the inner wall of the limiting groove 10, which guides and limits the up and down sliding direction of the first connecting rod 8, preventing the first connecting rod 8 from deviating or shaking when sliding, and ensuring that the brake plate 9 can accurately dock with the outer wall of the bushing 3. As the first link 8 continues to slide upwards, the brake plate 9 gradually approaches the outer wall of the bushing 3, eventually fitting tightly against it. Because the brake plate 9 adopts an arc-shaped structure, its curvature matches the curvature of the outer wall of the bushing 3, increasing the contact area with the bushing 3. Simultaneously, the rubber pad installed on the inner arc surface of the brake plate 9 further enhances friction, quickly preventing the bushing 3 from rotating, thus causing the turntable 4 to stop rotating synchronously. At this point, the character marker on the stopped turntable 4 that coincides with the position pointed to by the indicator needle 7 at the front end of the fixed shaft 6 is the character randomly assigned this time. The user can quickly determine the character based on the direction of the indicator needle 7, and then release the pedal 14. The pedal 14 returns to its original position under the elastic force of the return spring 15, which drives the second link 12, the first link 8 and the brake plate 9 back to their initial state, preparing for the next character assignment. It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
