Description

Technical Field

[0001] This utility model relates to the field of display rack technology, specifically a display rack for popularizing science education on cultivating plant root systems. Background Technology

[0002] Currently, most plant root display devices on the market are designed with fixed dimensions, primarily used to showcase the root growth of plants in pots of specific sizes. While this method is intuitive, its design limitations restrict its application to pots of limited sizes, failing to meet the needs of displaying roots from smaller or larger plants. Furthermore, to display different sized pots, users need to purchase multiple display devices of varying specifications, increasing both cost and operational complexity, significantly reducing the flexibility and versatility of the display system, and causing inconvenience to users.

[0003] More importantly, this single-size design has many limitations in practical applications. For example, when conducting educational or science exhibitions, it is necessary to display various plants at different growth stages and of different species. This requires the display racks to be able to accommodate different sized pots to ensure that all plant roots can be clearly displayed. However, existing display racks lack flexibility and adaptability, limiting the display range and affecting the display effect. Utility Model Content

[0019] 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.

[0020] Example 1: like Figures 1-3 As shown in the figure, a display rack for popularizing plant root science in one embodiment of this utility model includes a base 1 and a display platform 3 rotatably connected to the base 1. The display platform 3 has multiple display surfaces, and multiple vertically arranged clamping mechanisms 5 are installed on the display surfaces. The clamping mechanisms 5 clamp and fix the cultivation pots by clamping. This ensures that the front of the cultivation pot is not obstructed, especially for cultivation pots where the roots are displayed on the front or at the bottom. The clamping and fixing method avoids placing the pots on a flat surface, which would affect the display of the plant roots.

[0021] Among them, such as Figures 1-3 As shown, a connecting column 301 is fixedly connected to the lower end face of the display stand 3. A first insertion slot 102 matching the connecting column 301 is provided on the base 1. The connecting column 301 is inserted into the first insertion slot 102, and a first bearing 4 is fixedly connected between the outer wall of the first insertion slot 102 and the inner wall of the connecting column 301. That is, the display stand 3 is rotatably connected to the base 1 through the cooperation of the connecting column 301, the first insertion slot 102 and the first bearing 4.

[0022] like Figures 1-6 As shown, the clamping mechanism 5 includes a U-shaped mounting platform 6, which comprises a base plate and two side plates located at both ends of the base plate. A sliding groove 601 is formed on the base plate, and through holes 602 matching the sliding groove 601 are formed on the side plates. A pair of clamping arms 9 are slidably connected to the U-shaped mounting platform 6, and sliders 901 matching the sliding groove 601 are fixedly connected to the clamping arms 9. A bidirectional screw 7 matching the through hole 602 is rotatably connected to the U-shaped mounting platform 6, and threaded holes 9011 matching the bidirectional screw 7 are formed on the clamping arms 9. During rotation, the bidirectional screw 7 allows the two clamping arms 9 to move towards each other or away from each other. When the clamping arms 9 move towards each other, they can clamp the culture basin; when they move away from each other, they can release the culture basin.

[0023] Multiple second bearings 8 are fixedly connected between the through hole 602 and the bidirectional screw 7.

[0024] like Figures 1 to 7As shown, an anti-slip mechanism 10 is installed on the opposite surfaces of a pair of clamping arms 9. The anti-slip mechanism 10 can increase the friction between the clamping arms 9 and the culture pot, so as to reduce the possibility of the clamping arms 9 dropping the culture pot. The anti-slip mechanism 10 includes an air bladder 11, which is fixedly connected to the opposite surfaces of the clamping arms 9. Multiple elastic sleeves 12 are provided inside the air bladder 11, and a first spring 13 is fixedly connected inside the elastic sleeves 12. Multiple anti-slip protrusions 14 are fixedly connected to the opposite surfaces of the air bladder 11.

[0025] Specifically, when the culture basin is positioned between the two clamping arms 9, and the two clamping arms 9 move towards each other, they clamp the culture basin. First, the anti-slip protrusions 14 contact the culture basin. As the clamping arms 9 continue to move towards each other, the first spring 13 is compressed and deformed. Because the contact surfaces of the multiple first springs 13 with the culture basin are different, the degree of deformation of the first springs 13 also varies. That is, the air bladder 11 can adaptively clamp according to the external shape of the culture basin. With the intervention of the clamping arms 9, the culture basin can be firmly fixed.

[0026] In the above embodiment, its core advantage lies in the fact that the clamping arm 9 driven by the bidirectional screw 7, in conjunction with the self-adaptive anti-slip mechanism 10, can stably clamp cultivation pots of different shapes and sizes, suspending and fixing them securely without obstructing the root system, thus providing the observer with an optimal viewing angle without blind spots. Furthermore, it greatly enhances the intuitiveness of plant root system science demonstrations.

[0027] Example 2: To further enhance the scalability of the display rack, the following solution is adopted in this embodiment: like Figures 1-6 As shown, the display platform 3 has multiple vertically arranged second insertion slots 302 on its display surface. The display platform 3 also has mounting slots 303 located at the upper and lower ends of the second insertion slots 302. A wedge-shaped block 17 matching the mounting slot 3 is slidably connected to the display platform 3. A second spring 16 is fixedly connected between the wedge-shaped block 17 and the bottom wall of the mounting slot 303. A insertion block 15 matching the second insertion slot 302 is fixedly connected to the U-shaped mounting platform 6. The insertion block 15 has a limiting groove 1501 matching the wedge-shaped block 17.

[0028] like Figures 1-6As shown, the end face of the plug-in block 15 away from the U-shaped mounting platform 6 has a first inclined surface 1502 that matches the wedge block 17, and both ends of the wedge block 17 have second inclined surfaces 1701 that match the first inclined surface 1502. The second spring 16 is inserted into the second plug-in groove 302, and the first inclined surface 1502 contacts the second inclined surface 1701. As it is pushed further in, the wedge block 17 slides into the mounting groove 303 under the action of the pushing force, simultaneously compressing the second spring 16. When the position of the first inclined surface 1502 matches the position of the wedge block 17, the second spring 16 releases its deformation energy, allowing the wedge block 17 to be engaged in the first inclined surface 1502, thus achieving the snap-fit ​​installation of the clamping mechanism 5.

[0029] The clamping mechanism 5 is detachably mounted on the display stand 3 via the cooperation of the second spring 16, the wedge block 17, and the plug block 15. The number of clamping mechanisms 5 can be reduced or increased according to the size of the culture pot to accommodate culture pots with a larger size range. For example, when the height of the culture pot is too high, the original five clamping mechanisms 5 can be reduced to three clamping mechanisms 5, thus accommodating culture pots with greater height.

[0030] In other words, when dealing with taller cultivation pots, the number of clamping mechanisms 5 can be reduced to avoid obstruction, while when dealing with smaller cultivation pots, the number can be increased to ensure sufficient capacity for clamping. This high degree of scalability and adaptability greatly expands the applicability of the display rack, enabling it to easily meet the display needs of plant root cultivation pots of different sizes and at different teaching stages. It is not only easy to operate and reliably connected, but also significantly improves the flexibility and teaching efficiency of popular science displays.

[0031] In the above embodiments, the core advantage lies in the ingenious modular snap-fit ​​structure, which enables the clamping mechanism 5 to be quickly installed, flexibly adjusted, and securely fixed on the display surface. This design allows users to easily increase or decrease the number of clamping mechanisms 5 according to display needs without tools. Example 3: To enhance the attention of those receiving science education, the following approach is adopted in this embodiment: like Figure 2 As shown, an arc-shaped storage groove 101 is provided on the upper surface of the base 1. A shielding cloth 18 matching the arc-shaped storage groove 101 is installed on the base 1. One end of the shielding cloth 18 is fixedly connected to the bottom wall of the arc-shaped storage groove 101, and the other end is fixedly connected to a rigid connecting part 19. A rubber ring 20 is installed on the rigid connecting part 19. A connecting arm 21 matching the rubber ring 20 is fixedly connected to the upper end of the display stand 3. The rubber ring 20 can be fixed on the connecting arm 21.

[0032] The covering cloth 18 can cover multiple display surfaces of the display stand 3, leaving only one display surface exposed. When science educators are giving explanations, the remaining display surfaces can be covered with the covering cloth 18. During the observation phase, the covering cloth 18 can be stored in the curved storage slot 101. When other culture pots need to be displayed, the display stand 3 can be rotated to switch display surfaces.

[0033] The covering cloth 18 has multiple fold lines 1801.

[0034] In the above embodiments, an important teaching aid function is introduced by setting up an arc-shaped storage slot 101 and an unfoldable covering cloth 18 that matches the arc-shaped storage slot 101. This design allows science educators to selectively cover parts of the display surface according to the progress of the explanation, thereby precisely guiding the observer's attention to the specific plant sample that needs attention. This controllable information presentation method effectively avoids the distraction that may be caused by displaying multiple samples at the same time, and conforms to the gradual cognitive pattern.

[0035] When not in use, the covering cloth 18 can be easily stored in the curved storage slot 101, keeping the device's appearance neat. This design combines the physical function of the display rack with the concept of attention management in teaching, not only optimizing the observation experience but also actively participating in the control of the teaching pace, significantly improving the guidance and interactivity of popular science explanations, and making the display process more targeted and professional.

[0036] Example 4: like Figure 1 As shown, multiple casters 2 are fixedly connected to the lower end of the base 1, and a handle 22 is fixedly connected to the base 1. By adding casters 2 and handle 22, this embodiment can further improve the mobility of the display rack and significantly save labor in moving the display rack.

[0037] Obviously, the above-described embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
