[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides a specific embodiment of a vegetable seedling packaging box, comprising a box body 1 and a base 3, wherein a telescopic cover assembly 2 is provided at the upper end of the box body 1, and an installation and removal assembly 4 is provided between the box body 1 and the base 3.

[0035] The telescopic cover assembly 2 includes a first cover 5, a second cover 6 slidably disposed inside the first cover 5, and a third cover 7 slidably disposed inside the second cover 6. Sliding grooves 8 are formed on both sides of the inner walls of the first cover 5 and the second cover 6. Sliding blocks 9 are fixedly connected to both sides of the second cover 6 and the third cover 7. A reset groove 10 is formed on one side of the inner wall of each of the sliding grooves 8. Multiple connecting rods 11 are movably disposed inside each of the reset grooves 10. A positioning block 12 is fixedly connected to one end of each connecting rod 11 located in the same reset groove 10 near the corresponding sliding block 9. A positioning groove is formed on one side of each of the sliding blocks 9. 13. Multiple sliding blocks 9 are slidably set within corresponding sliding grooves 8, and multiple positioning blocks 12 are engaged within corresponding positioning slots 13. By sliding the sliding blocks 9 within corresponding sliding grooves 8 and engaging the positioning blocks 12 within corresponding positioning slots 13, the second cover 6 or the third cover 7 can be fixed at the current height. Multiple connecting rods 11 have movably fitted return springs 14 on their outer walls. The two ends of the multiple return springs 14 are respectively fixedly connected to the inner walls of the corresponding positioning blocks 12 and the return grooves 10 on opposite sides. Multiple positioning blocks 12 are slidably set within corresponding return grooves 10. By engaging the return springs 14... 4. Effective restriction is implemented, and the positioning block 12 is slidably set within the corresponding reset groove 10, thereby allowing the positioning block 12 to effectively pop out from the corresponding reset groove 10. With the telescopic cover assembly 2, the cover can be stretched and expanded according to the height of the seedling to be loaded, thus expanding the cover volume. This allows the packaging box to be suitable for seedlings of various heights, preventing the seedlings from being crushed during sealing and improving the applicability of the device. Multiple connecting rods 11 located in the same reset groove 10 have their ends away from the corresponding sliding block 9 passing through the corresponding first cover 5 and second cover 6 and are fixedly connected to a pull plate 15. The third cover 7 has two sides... Each cover is fixedly connected with a protrusion 27. The pull plate 15 facilitates the movement of the connecting rod 11 and the second cover 6. The protrusion 27 also facilitates the movement of the third cover 7. Both sides of the first cover 5 are rotatably connected with buckles 25, and both sides of the box body 1 are fixedly connected with clips 26. Both buckles 25 engage with the corresponding clips 26. The buckles 25 and clips 26 are used to snap the first cover 5 and the box body 1 together. The upper end of the third cover 7 has a vent hole 28 to maintain air circulation and ensure the health of the seedlings during transportation and storage.

[0036] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6The installation and removal assembly 4 includes two fixing blocks 17 and two pressing blocks 20. The inner walls of the housing 1 have sliding grooves 16 and spring-loaded grooves 19 on both sides. The two fixing blocks 17 slide within their respective sliding grooves 16, and the two pressing blocks 20 slide within their respective spring-loaded grooves 19. The base 3 has fixing slots 18 on both sides, and the two fixing blocks 17 engage within their respective fixing slots 18. A connecting groove 22 is provided between each of the two sliding grooves 16 and the corresponding spring-loaded groove 19. A connecting block 23 is movably installed inside each of the two connecting grooves 22. Both connecting blocks 23 are fixedly connected to their respective fixing blocks 17 and pressing blocks 20. The two pressing blocks 20 and their corresponding spring-loaded grooves 19... Multiple return springs 21 are fixedly connected between the inner walls of opposite sides of the groove 19. With the installation and removal component 4, the base 3 can be installed, fixed, or unlocked and disassembled. This allows the base 3 with the corresponding size seedling tube 24 to be installed and fixed according to the size of the seedlings to be loaded. Alternatively, when seedling loading is not required, the base 3 can be removed to increase the effective volume of the box 1, thus making it usable as a storage box. This fully utilizes the space of the packaging box and improves its multi-functionality. Multiple seedling tubes 24 are fixedly connected to the upper end of the base 3. With the seedling tubes 24, the seedlings can be stored independently in the seedling tubes 24 to avoid the seedlings from getting tangled together.

[0037] Working principle: By incorporating a telescopic cover assembly 2, the cover can be stretched and unfolded according to the height of the seedlings to be loaded, making the packaging box suitable for seedlings of various heights and sizes. This avoids crushing the seedlings when sealing the cover, improving the applicability of the device. Specifically, when it is necessary to stretch and unfold the cover, the pull plate 15 on the second cover 6 or the protrusion 27 on the third cover 7 is lifted, causing the corresponding sliding block 9 to move upward. This causes the positioning block 12 to meet the positioning slot 13. At this time, the positioning block 12 can be popped out and locked into the positioning slot 13 by the provided return spring 14, thus fixing the second cover 6 or the third cover 7 at the current height, thereby realizing the adjustment of the cover volume. The expansion allows it to accommodate seedlings of different heights. Pulling the corresponding pull plate 15 releases the height fixation and restores the retracted state. Finally, the use of the base 3 and the seedling tube 24 can be achieved by controlling the movement of the pressing block 20, which causes the fixing block 17 to engage or disengage from the fixing slot 18. This allows for the installation, fixing, unlocking, and disassembly of the base 3. Thus, the base 3 with the corresponding size seedling tube 24 can be installed and fixed according to the size of the seedlings to be loaded. Alternatively, when seedling loading is not required, the base 3 can be removed to increase the effective volume of the box 1, allowing it to be used as a storage box, making full use of the packaging box space and improving its multifunctionality.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
