Description

Technical Field

[0001] This utility model relates to the field of waste sorting science popularization and publicity technology, and in particular to a waste sorting science popularization display device. Background Technology

[0002] In existing waste sorting science popularization campaigns, common display devices are mostly static posters, bulletin boards, or simple graphic panels. Their information presentation methods are fixed and lack interactivity, making the public, especially children and teenagers, easily bored during the learning process, resulting in poor participation and retention. Although some venues have introduced electronic display devices with touchscreens and waste sorting mini-games through software programs, these devices are costly, complex to maintain, and dependent on electricity and software systems, making them prone to malfunctions and difficult to popularize in outdoor or resource-limited community environments. Furthermore, most existing science popularization devices have a fixed height and cannot be adjusted according to the user's height, causing inconvenience for children and affecting their learning experience. Therefore, we propose a waste sorting science popularization display device. Utility Model Content

[0003] The main purpose of this utility model is to provide a waste sorting science popularization and display device, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A waste sorting science popularization display device includes a mounting base plate with mounting holes. Sleeve rods are fixedly installed on the upper left and right sides of the mounting base plate. Telescopic rods are slidably connected inside the two sleeve rods. A display panel is fixedly connected to the top of the two telescopic rods. Multiple science popularization components are provided at the front end of the display panel. A support plate is fixedly welded between the two sleeve rods, and an adjustment component is fixedly installed at the lower end of the display plate, with the adjustment component threadedly connected to the support plate.

[0005] Preferably, the science popularization component includes two connecting strips symmetrically connected to the front end of the display board, a waste label plate slidably connected between the two connecting strips, and a classification display area opened on the display board and corresponding to the position of the waste label plate, wherein the classification display area displays the corresponding waste classification label.

[0006] By adopting the above technical solution, the waste label can slide along the connecting strip. In the initial state, it covers the classification display area, so that users cannot directly see the correct classification. They need to judge based on the waste picture first, and then reveal the answer by sliding. This realizes the interactive learning mode of "thinking-verification", which effectively improves the fun and memory effect of learning waste classification knowledge.

[0007] Preferably, the waste labeling board includes a movable board, the front end of which is provided with a waste labeling area, and the waste labeling area displays waste image information, and one end of the movable board is fixedly connected to a handle.

[0008] By adopting the above technical solution: the movable plate is used to carry the garbage image information, making it easier for users to identify and judge the type of garbage, and the handle makes it easier for users to apply force, so as to realize the smooth sliding of the garbage label plate between the connecting strips, which improves the convenience of operation and human-computer interaction experience.

[0009] Preferably, each of the two connecting strips has a sliding groove at its opposite ends, and each of the two sliding grooves has a positioning rod on its left and right inner walls.

[0010] By adopting the above technical solution: the chute provides a guide track for the slider, ensuring that the waste label plate slides smoothly along a straight line; the positioning rod is set at both ends of the chute, which is used to cooperate with the positioning rod on the slider to achieve snap-fit ​​positioning, ensuring that the waste label plate can be stably fixed in the initial covering position and the offset position after sliding, preventing accidental displacement, and improving the reliability and accuracy of the device.

[0011] Preferably, a slider that is slidably connected to the slide groove is fixedly welded to one side of both the upper and lower ends of the movable plate, and a positioning plug that engages with the positioning rod is fixedly welded to both ends of the slider.

[0012] By adopting the above technical solution: the slider is embedded in the chute to achieve a sliding connection, ensuring the smooth movement of the moving plate; the positioning rod cooperates with the positioning rod on the inner wall of the chute, and automatically engages when the waste label plate slides to the start or end position to achieve position locking, thereby ensuring the stability of the display status during the learning and verification process, and enhancing the practicality of the device and the user experience.

[0013] Preferably, the adjustment component includes a protective frame, which is a U-shaped structure and fixedly connected to the lower end of the display panel. A forward and reverse motor is fixedly installed inside the protective frame, and a transmission screw is fixedly connected to the output end of the forward and reverse motor. The transmission screw is threadedly connected to the support plate.

[0014] By adopting the above technical solution: the forward and reverse motors drive the transmission screw to rotate, and the screw and the support plate are threaded together to convert the rotational motion into the vertical lifting motion of the display board, so as to realize automatic height adjustment; the protective frame not only protects the motor and the screw, but also enhances the stability of the structure, making the device adaptable to the needs of users of different heights, and improving its applicability and human-machine friendliness.

[0015] Preferably, a limiting plate is fixedly connected to both of the telescopic rods, and the limiting plate is located at the upper end of the sleeve rod.

[0016] By adopting the above technical solution, a safety limit function is achieved, ensuring the operational safety and structural stability of the device when adjusting its height, and extending the service life of the equipment.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the ingenious design of science popularization components, an interactive waste sorting learning mode of "think first, then verify" is realized. Users need to actively think and judge the waste category when they cannot directly see the correct answer. Only after making a judgment can they see the correct label in the classification display area below by sliding the waste label board. This design effectively avoids passively receiving information and significantly enhances the sense of participation, challenge and memory depth of learning. The locking cooperation between the positioning plug and the positioning rod ensures the smooth sliding process and stable positioning at the starting (covering) and ending (staggered) positions, ensuring the reliability of the device and the user experience, and greatly improving the fun and teaching effect of waste sorting science popularization.

[0018] 2. The integrated electric height adjustment component significantly improves ease of use and applicability. Through the threaded engagement of the transmission screw driven by the forward and reverse motors with the support plate, stepless and smooth height adjustment of the display board can be achieved, allowing users of different heights, such as children and adults, to operate and view comfortably. This reflects excellent ergonomic design. The protective frame not only protects the internal transmission mechanism but also enhances the overall structural integrity. This design enables the device to flexibly adapt to diverse user groups, greatly enhancing its practicality and promotional value in different scenarios such as communities, schools, and exhibition halls.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides a technical solution: A waste sorting science popularization display device includes a mounting base plate 1 with mounting holes 11. Sleeve rods 2 are fixedly installed on the upper left and right sides of the mounting base plate 1. Telescopic rods 3 are slidably connected inside the two sleeve rods 2. A display board 4 is fixedly connected to the top of the two telescopic rods 3. Multiple science popularization components 5 are provided at the front end of the display board 4.

[0025] In this embodiment, the science popularization component 5 includes two connecting strips 52 symmetrically connected to the front end of the display board 4, a garbage label plate 51 slidably connected between the two connecting strips 52, and a classification display area 53 on the display board 4 corresponding to the position of the garbage label plate 51. The classification display area 53 displays the corresponding garbage classification label. The garbage label plate 51 includes a movable plate 511. The front end of the movable plate 511 is provided with a garbage label area 513, and the garbage label area 513 displays garbage image information. One end of the movable plate 511 is fixedly connected to a handle 512. The opposite ends of the two connecting strips 52 are provided with grooves 521, and the left and right inner walls of the two grooves 521 are provided with positioning rods 522. The upper and lower ends of the movable plate 511 are fixedly welded with sliders 514 that are slidably connected to the grooves 521. The two ends of the sliders 514 are fixedly welded with positioning inserts 515 that engage with the positioning rods 522.

[0026] Through the above scheme: the user first observes the specific garbage image displayed in the garbage label area 513 at the front of the garbage label board 51, and judges its category based on existing knowledge. At this time, the garbage label board 51 covers the classification display area 53, and the user cannot directly see the correct classification label below, thus avoiding knowing the answer in advance; subsequently, the user pulls the handle 512, causing the moving plate 511 to slide along the slide groove 521 of the connecting strip 52. The positioning rod 515 on the slider 514 will disengage from the positioning rod 522 during the sliding process. When the moving plate 511 is completely removed and offset from the classification display area 53, Positioning rod 515 will re-engage with positioning rod 522 on the other side to achieve positioning. At this time, the correct waste classification label in the lower classification display area 53 is fully revealed, allowing users to check the answer and learn the correct classification knowledge. This realizes an interactive waste classification learning mode of "think first, then verify". When users cannot see the correct answer directly, they need to actively think and judge the waste category. Only after completing the judgment can they view the correct label in the lower classification display area for verification by sliding the waste label board. This design effectively avoids passively receiving information and significantly enhances the sense of participation, challenge and memory depth of learning.

[0027] In this embodiment, a support plate 6 is fixedly welded between the two sleeve rods 2. An adjustment component 7 is fixedly installed at the lower end of the display plate 4, and the adjustment component 7 is threadedly connected to the support plate 6. The adjustment component 7 includes a protective frame 71, which is a U-shaped structure and fixedly connected to the lower end of the display plate 4. A forward and reverse motor 72 is fixedly installed inside the protective frame 71. A transmission screw 73 is fixedly connected to the output end of the forward and reverse motor 72, and the transmission screw 73 is threadedly connected to the support plate 6. Limiting plates 31 are fixedly connected to both telescopic rods 3, and the limiting plates 31 are located at the upper end of the sleeve rods 2.

[0028] The above solution involves starting the forward and reverse motors 72, which drive the transmission screw 73 to rotate. Since the transmission screw 73 is threadedly connected to the support plate 6 fixed between the sleeve rods 2, the rotation of the screw is converted into the overall lifting and lowering motion of the display panel 4, causing the telescopic rod 3 to extend and retract within the sleeve rods 2. This allows for stepless and stable adjustment of the height of the display panel 4, enabling users of different heights, such as children and adults, to operate and view the display comfortably. This demonstrates excellent ergonomic design. The limiting plate 31 prevents the telescopic rod 3 from extending excessively, ensuring the safety and stability of the lifting process.

[0029] It should be noted that this utility model is a waste sorting science popularization and demonstration device. During use, it is first fixed in a suitable position using the mounting holes 11 on the mounting base plate 1 to ensure stability. When learning about waste sorting, the user first observes the specific waste image displayed in the waste label area 513 at the front of the waste label plate 51 and judges its category based on existing knowledge. At this time, the waste label plate 51 covers the classification display area 53, preventing the user from directly seeing the correct classification label below, thus avoiding knowing the answer in advance. Subsequently, the user pulls the handle 512, causing the moving plate 511 to slide along the groove 521 of the connecting strip 52. During the sliding process, the positioning rod 515 on the slider 514 will engage with the positioning rod 521. When the movable plate 511 is completely removed and misaligned with the classification display area 53, the positioning rod 515 will re-engage with the positioning rod 522 on the other side to achieve positioning. At this time, the correct waste classification label in the classification display area 53 below is fully exposed, allowing users to check the answers and learn the correct classification knowledge. In addition, to accommodate the needs of users of different heights, the forward and reverse motors 72 can be started to drive the transmission screw 73 to rotate. Since the transmission screw 73 is threadedly connected to the support plate 6 fixed between the sleeve rods 2, the rotation of the screw will be converted into the overall lifting and lowering motion of the display plate 4, driving the telescopic rod 3 to extend and retract within the sleeve rods 2, thereby adjusting the height of the display plate 4. The limiting plate 31 can prevent the telescopic rod 3 from extending excessively, ensuring the safety and stability of the lifting and lowering process.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
