Description

Technical Field

[0001] This utility model relates to the field of terminal technology, and in particular to a self-service terminal for academic affairs. Background Technology

[0002] Self-service terminals for academic affairs are intelligent devices widely used in universities, primary and secondary schools, and educational management institutions. They primarily assist in teaching management and student self-service. These devices integrate multiple functions such as information inquiry, grade printing, timetable viewing, payment processing, and document recognition, greatly facilitating the daily academic affairs processing for teachers and students and improving school management efficiency and service quality. With the continuous advancement of smart campus construction, self-service terminals for academic affairs are playing an increasingly important role in the process of educational informatization. As a key link in the interaction between teachers / students and the academic affairs system, the ease of operation, user-friendliness, and structural functionality of these terminals have a decisive impact on the overall user experience and management efficiency. Especially in the core aspect of human-computer interaction interface design and display adjustment, existing self-service terminals for academic affairs are gradually revealing a series of obvious limitations and technical problems when dealing with the needs of users of different heights, viewing angles, or usage habits.

[0003] Specifically, existing self-service terminals for academic affairs face prominent problems in practical applications, such as non-adjustable display screen angles, fixed heights, and poor adaptability. For example, utility model patent CN216352628U discloses a self-service payment terminal for academic affairs. By setting up a linkage structure between a knob, a connecting rod, a limit block, and a positioning block, it enables quick assembly and disassembly between the device body and the side cover, facilitating staff to inspect and clean the inside of the equipment, and improving maintenance efficiency and maintainability to a certain extent.

[0004] However, in practical use, this terminal still has significant shortcomings: First, the display screen is fixed in its installation method and cannot be adjusted in height or angle according to the user's height or posture, resulting in blind spots or inconvenience for some users. Second, it lacks screen visibility optimization design for different lighting environments; under strong light, the screen reflects light severely, affecting information reading. Third, the fixed position of the operating interface can easily cause fatigue when standing for long periods, reducing the comfort of human-computer interaction. Finally, because the display screen cannot be flexibly adjusted, some users need to bend over or stand on tiptoe to view information, which not only affects the user experience but may also pose safety hazards. These problems directly limit the flexibility and applicability of the self-service terminal in practical use, increase operational complexity, and make it difficult to meet the diverse, user-friendly, and barrier-free service needs of modern educational environments. Therefore, in response to the many shortcomings of existing technologies, we urgently need an innovative self-service terminal for academic affairs to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a self-service terminal for academic affairs, which solves the problems of existing technologies that cannot adjust the height or angle according to the user's height or sitting posture, resulting in blind spots or inconvenience for some users; secondly, the lack of screen visibility optimization design for different lighting environments, resulting in severe screen reflection under strong light, which affects the information reading effect.

[0006] To achieve the above objectives, this utility model provides a self-service teaching terminal, including a support frame, and an inner frame slidably connected to the inner side of the support frame, and a support rod rotatably connected to the inner side of the inner frame.

[0007] A bearing sleeve is fitted onto the bearing rod, and a display screen is fixedly connected to one side of the bearing sleeve. A side frame is fixedly connected to one side of the bearing frame, and a side rod is rotatably connected to the inner side of the side frame. The two ends of the side rod are respectively engaged with the two ends of the bearing rod. A limiting sleeve is fitted onto one end of the side rod, and a limiting rod is provided on one side of the side frame. One end of the limiting rod passes through the side frame. Several limiting grooves are opened on the limiting sleeve to cooperate with the limiting rod. A cylinder is fixedly connected to the bottom side of the bearing frame by bolts, and the output shaft of the cylinder passes through the bottom of the bearing frame and is fixedly connected to the bottom of the inner frame.

[0008] The load-bearing frame has four fixedly connected universal self-locking wheels at its bottom corners, and two fixedly connected folding plates on the bottom sides of the inner frame. The bottom of each of the two folding plates is fixedly connected to the bottom of the inner side of the load-bearing frame.

[0009] The inner frame has sliders fixedly connected to both sides, and both sliders are slidably connected to the inner wall of the support frame through a groove.

[0010] Both ends of the load-bearing rod are rotatably connected to the inner wall of the inner frame via a rotating shaft, and both ends of the side rod are rotatably connected to the inner wall of the side frame via a rotating shaft.

[0011] The support rod has a first gear fitted on both ends, and the side rod has a second gear fitted on both ends, with the two first gears meshing with the two second gears respectively.

[0012] The side rod has a handle sleeve on both ends, and a tension spring is fitted on one end of the limiting rod. The limiting rod is elastically connected to one side of the side frame through the tension spring.

[0013] This utility model discloses a self-service teaching terminal. By incorporating a lifting linkage structure between a cylinder and the inner frame, combined with a sliding connection between the support frame and the inner frame, it achieves height adjustment of the display screen. This effectively solves the problem of traditional terminals being unable to accommodate users of different heights due to their fixed height, thus improving the device's versatility and user-friendliness. Through a rotating connection structure between the support rod and the support sleeve, combined with a gear meshing transmission between the side rod and the support rod in the side frame, the display screen can be flexibly tilted according to the user's viewing angle, avoiding visual interference caused by strong glare and improving the readability and display effect of the screen information. By incorporating a limiting structure between the limiting sleeve and the limiting rod, and setting multiple limiting grooves on the limiting sleeve, it achieves precise control and stable locking of the display screen's adjustment angle, enhancing the safety and reliability of the device. Furthermore, the terminal has a reasonable overall structural layout, with tight cooperation between components, and simple and intuitive adjustment operations, significantly reducing the user's learning cost and operational difficulty, and improving the comfort and efficiency of human-computer interaction.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-5 ,

[0023] A self-service teaching terminal includes a support frame 1, and an inner frame 2 is slidably connected to the inner side of the support frame 1, and a support rod 10 is rotatably connected to the inner side of the inner frame 2.

[0024] A bearing sleeve 12 is fitted onto the bearing rod 10, and a display screen 3 is fixedly connected to one side of the bearing sleeve 12. A side frame 9 is fixedly connected to one side of the bearing frame 1, and a side rod 13 is rotatably connected to the inner side of the side frame 9. The two ends of the side rod 13 are respectively engaged with the two ends of the bearing rod 10. A limiting sleeve 15 is fitted onto one end of the side rod 13, and a limiting rod 16 is provided on one side of the side frame 9. One end of the limiting rod 16 passes through the side frame 9. The limiting sleeve 15 has several limiting grooves 18 that cooperate with the limiting rod 16. A cylinder 7 is fixedly connected to one side of the bottom of the bearing frame 1 by bolts, and the output shaft of the cylinder 7 passes through the bottom of the bearing frame 1 and is fixedly connected to the bottom of the inner frame 2.

[0025] When a user needs to use the self-service teaching terminal, first push the entire support frame 1 to a suitable position. Then, according to the user's height or sitting posture, activate the cylinder 7 installed on one side of the bottom of the support frame 1. The output shaft of the cylinder 7 passes through the bottom of the support frame 1 and is fixedly connected to the bottom of the inner frame 2. Under the action of the cylinder 7, the inner frame 2 is driven to slide along the inner side of the support frame 1, realizing the overall up and down movement adjustment of the display screen 3. At the same time, the inner frame 2 is provided with a rotatably connected support rod 10. A support sleeve 12 is sleeved on the support rod 10. One side of the support sleeve 12 is fixedly connected to the display screen 3, so that the display screen 3 can rotate together with the support rod 10. In addition, a side frame 9 is provided on one side of the support frame 1. The side frame 9 is rotatably connected to a side... The two ends of the side rod 13 are connected to the two ends of the support rod 10 by gear meshing. Therefore, when the user manually rotates the side rod 13, the support rod 10 can be rotated synchronously through gear transmission, thereby realizing the tilt angle adjustment of the display screen 3. After the angle adjustment is completed, in order to prevent the display screen 3 from shifting due to external force, a limiting sleeve 15 can be set at one end of the side rod 13. The limiting sleeve 15 has multiple limiting grooves 18. By inserting the limiting rod 16 into the corresponding limiting groove 18, the side rod 13 is locked, ensuring the stability and safety of the display screen 3 after adjustment. The entire adjustment process can be completed without complicated tools, is easy to operate, highly adaptable, and can meet the usage needs of different people in various scenarios.

[0026] Furthermore, universal self-locking wheels 8 are fixedly connected to the four corners at the bottom of the support frame 1, and folding plates 6 are fixedly connected to both sides at the bottom of the inner frame 2. The bottom of the two folding plates 6 is fixedly connected to the inner bottom of the support frame 1. When the equipment needs to be moved, the user can move it flexibly through the universal self-locking wheels 8 and lock the wheels to prevent slippage after reaching the designated position. When the equipment is stationary, the folding plates 6 can serve as an auxiliary support structure to enhance the overall stability. They play a role in structural reinforcement and load-bearing buffer in the internal space of the support frame 1, thereby improving the ease of movement and safety of use of the equipment, and achieving the technical effect of facilitating rapid deployment and improving the stability of terminal operation.

[0027] Furthermore, sliders 4 are fixedly connected to both sides of the inner frame 2, and both sliders 4 are slidably connected to the inner wall of the support frame 1 through the slide groove 5. During the process of the cylinder 7 driving the inner frame 2 to slide up and down, the sliders 4 slide along the slide groove 5, so that the inner frame 2 maintains a stable straight trajectory during the lifting process, avoiding shaking or deviation caused by uneven force, thereby improving the accuracy and stability of the lifting process of the display screen 3, and achieving the technical effect of improving adjustment accuracy and enhancing the reliability of equipment operation.

[0028] Furthermore, both ends of the support rod 10 are rotatably connected to the inner wall of the inner frame 2 via rotating shafts, and both ends of the side rod 13 are rotatably connected to the inner wall of the side frame 9 via rotating shafts. When the user manually rotates the side rod 13, it drives the support rod 10 to rotate synchronously through gear transmission, ensuring that the support rod 10 has good rotational freedom and structural stability during rotation. At the same time, it reduces the frictional resistance between rotating parts, improves the flexibility of angle adjustment and the smoothness of operation, and achieves the technical effect of enhancing angle adjustment performance and extending the service life of the equipment.

[0029] Furthermore, a first gear 11 is sleeved on both ends of the support rod 10, and a second gear 14 is sleeved on both ends of the side rod 13. The two first gears 11 are meshed with the two second gears 14 respectively. When the user rotates the side rod 13, the second gear 14 drives the first gear 11 to rotate synchronously, thereby realizing the linkage adjustment of the angle of the support rod 10 and the display screen 3. This makes the angle adjustment more precise and responsive, enhances the consistency of the human-computer interaction experience and the adjustment efficiency, and achieves the technical effect of improving the angle adjustment accuracy of the display screen 3 and enhancing the linkage of adjustment.

[0030] Furthermore, handle gloves 19 are fitted onto both ends of the side rod 13, and a tension spring 17 is fitted onto one end of the limiting rod 16. One end of the limiting rod 16 is elastically connected to one side of the side frame 9 through the tension spring 17. When the user needs to adjust the angle of the display screen 3, they can hold the handle gloves 19 and rotate them. After adjustment, the limiting rod 16 is pulled and released, so that it automatically inserts into the corresponding limiting groove 18 under the action of the tension spring 17 to complete the locking. This simplifies the operation steps and improves the automation level of the structure, achieving the technical effects of easy and quick adjustment, improved ease of use and human-computer interaction experience.

[0031] In summary:

[0032] When a user needs to use the self-service academic affairs terminal, the entire device is first pushed to a suitable position by the universal self-locking wheels 8 fixedly connected to the four corners at the bottom of the support frame 1, and the wheels are locked after reaching the designated location to prevent slippage. At the same time, folding plates 6 are provided on both sides of the bottom of the inner frame 2, and their bottoms are fixedly connected to the inside of the support frame 1, which provides auxiliary support when the device is stationary, enhancing the overall structural stability and load-bearing capacity. Subsequently, according to the user's height or sitting posture, the cylinder 7 installed on one side of the bottom of the support frame 1 is activated, and its output shaft passes through the bottom of the support frame 1 and is fixed to the bottom of the inner frame 2. The inner frame 2 is fixedly connected to the inner frame 1, thereby driving the inner frame 2 to slide along the inner side of the support frame 1, realizing the overall up and down movement adjustment of the display screen 3. In order to improve the stability during the lifting process, sliders 4 are provided on both sides of the inner frame 2, and a sliding connection is formed between the inner frame 2 and the inner wall of the support frame 1 through the sliding groove 5, ensuring that the inner frame 2 maintains a straight trajectory during the lifting process and avoids shaking or deviation. At the same time, the inner frame 2 is provided with a rotatable support rod 10 inside, and a support sleeve 12 is sleeved on the support rod 10. One side of the support sleeve 12 is fixedly connected to the display screen 3, so that the display screen 3 can rotate together with the support rod 10 to realize the angle adjustment function. In addition, a side frame 9 is provided on one side of the support frame 1, and a side rod 13 is rotatably connected inside the side frame 9. The two ends of the side rod 13 are connected to the inner wall of the side frame 9 through rotating shafts, and are linked to the two ends of the support rod 10 through gear meshing. The support rod 10 has a first gear 11 at both ends, and the side rod 13 has a second gear 14 at both ends. The two mesh with each other, so when the user manually rotates the side rod 13, the support rod 10 can be rotated synchronously through gear transmission, thereby realizing the tilt angle adjustment of the display screen 3. For ease of operation, the two ends of the side rod 13 are also fitted with gloves 19 to improve grip comfort. After the angle adjustment is completed, to prevent the display screen 3 from shifting due to external force, a limiting sleeve 15 can be set at one end of the side rod 13. The limiting sleeve 15 has multiple limiting slots 18, and the side rod 13 is locked by inserting the limiting rod 16 into the corresponding limiting slot 18. A tension spring 17 is also sleeved at one end of the limiting rod 16, so that it can automatically reset and insert into the limiting slot 18 after release, realizing quick locking and improving the safety and reliability of the equipment. The entire adjustment process can be completed without complicated tools, is easy to operate, and has strong adaptability, which can meet the usage needs of different people in various scenarios.By setting up a lifting linkage structure between cylinder 7 and inner frame 2, combined with a sliding guide structure between slider 4 and slide groove 5, the height adjustment function of display screen 3 is realized, effectively solving the problem that traditional terminals cannot adapt to users of different heights due to fixed height, thus improving the versatility and user-friendliness of the equipment. By setting up a rotating connection structure between support rod 10 and support sleeve 12, combined with the gear meshing transmission between first gear 11 and second gear 14, display screen 3 can be flexibly tilted according to the user's viewing angle, avoiding visual interference caused by strong light reflection, and improving the readability and display effect of screen information. By setting up a limiting structure between limiting sleeve 15 and limiting rod 16, and setting a tension spring 17 at one end of limiting rod 16 to achieve elastic reset locking, the stability and safety of display screen 3 after adjustment are enhanced, improving the reliability and operation of the equipment. Convenience: By setting handle gloves 19 at both ends of the side rod 13, the user's feel and comfort during operation are improved, and the adjustment process is further simplified. The structural cooperation between the universal self-locking wheels 8 and the folding plate 6 at the bottom of the support frame 1 not only improves the ease of movement of the equipment, but also enhances the overall stability in the static state, achieving the technical effect of facilitating rapid deployment and improving the stability of terminal operation. The overall structural layout is reasonable, the components are closely matched, and the adjustment operation is simple and intuitive, which greatly reduces the user's learning cost and operation difficulty, improves the comfort of human-computer interaction and the efficiency of use, effectively solves the problems of fatigue and safety hazards caused by long-term use of traditional academic affairs self-service terminals, meets the urgent needs of modern smart campus construction for diversified, barrier-free and personalized service terminals, and provides strong technical support for the development of educational informatization.
