It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0027] Embodiment: As Figure 1-6 shown, the present utility model provides a technical solution, a box assembly opening and closing mechanism, including a seed box 1. One end of the top of the seed box 1 is provided with a mounting seat 2. A box cover 3 is rotatably mounted outside the mounting seat 2. A fixed shaft 4 is mounted inside the top of the seed box 1. A support plate 5 is rotatably mounted outside the fixed shaft 4. An installation card slot 6 is opened at the bottom of the support plate 5. A torsion spring 7 is sleeved outside the fixed shaft 4. One end of the torsion spring 7 contacts the support plate 5, and the other end of the torsion spring 7 is placed inside the seed box 1 to facilitate the support of the support plate 5. Limiting groove plates 8 are symmetrically arranged at both ends of the top of the support plate 5. A limiting rod 9 is clamped between the two limiting groove plates 8. Bent rods 10 are arranged at both ends of the limiting rod 9. The support plate 5 and the limiting groove plates 8 are of an integral structure. The limiting rod 9 and the bent rods 10 are of an integral structure. The bent rod 10 at one end of the limiting rod 9 is placed inside the limiting groove plate 8, and the bent rod 10 at the other end of the limiting rod 9 contacts the inside of the box cover 3 to facilitate the installation of the limiting rod 9. Sliding seats 11 are symmetrically mounted inside the box cover 3. A sliding hole 12 is opened in the middle of the sliding seat 11. The sliding hole 12 is of a long strip structure. Both ends of the limiting rod 9 are slidably clamped inside the sliding holes 12 of the sliding seats 11 to facilitate the sliding of the limiting rod 9;

[0028] Another end of the top of the seed box 1 is provided with a fixed seat 13. A convex stopper 14 is mounted in the middle of the fixed seat 13. A rotating buckle plate 15 is rotatably mounted at the bottom of the fixed seat 13. Activity grooves 16 are symmetrically opened on both sides of the rotating buckle plate 15. A communication hole 17 is opened at the bottom of the rotating buckle plate 15. A limiting top groove 18 is opened at the inner top of the activity groove 16. An activity card block 19 is movably clamped inside the activity groove 16. A limiting top block 20 is mounted at the top end of the activity card block 19. The limiting top block 20 is clamped with the limiting top groove 18. One end of an elastic connecting rod 21 is connected to the inner side wall of the activity groove 16 to facilitate the installation of the activity card block 19. An elastic connecting rod 21 is mounted at a position close to the inner side of the activity groove 16 on one end face of the activity card block 19. A clamping vertical groove 22 is opened at the top of the activity card block 19. A communication groove 23 is opened at the bottom end of the activity card block 19;

[0029] At the top of the box cover 3, fixed clamping blocks 24 are symmetrically installed. The movable groove 16 communicates with the through hole 17, and the clamping vertical groove 22 communicates with the connecting groove 23, facilitating the clamping connection between the fixed clamping block 24 and the movable clamping block 19. At the bottom of the fixed clamping block 24, a fixed clamping groove 25 is provided. The fixed clamping block 24 passes through the through hole 17 and the connecting groove 23, and the fixed clamping groove 25 of the fixed clamping block 24 is clamped with the bottom position of the clamping vertical groove 22, thereby limiting the box cover 3 and closing the box cover 3. On one side of the top of the fixed clamping block 24, a clamping inclined surface 26 is provided, and a clamping groove 27 is provided at one end of the box cover 3.

[0030] The working principle and usage process of the present utility model: When opening the seed box 1, first press the movable clamping block 19 and the elastic connecting rod 21 into the movable groove 16. The movable clamping block 19 drives the clamping vertical groove 22 to move, separating its position from the fixed clamping groove 25 of the fixed clamping block 24, releasing the clamping connection between the fixed clamping block 24 and the movable clamping block 19. At this time, rotate the rotating buckle plate 15 upward so that the rotating buckle plate 15 contacts the convex stop block 14, and the rotating buckle plate 15 is separated from the box cover 3. At this time, the torsion spring 7 resets, and one end of the torsion spring 7 pushes the support plate 5 upward, thereby pushing the box cover 3 to rotate upward. The limiting rod 9 slides inside the sliding hole 12 of the sliding seat 11, opening the box cover 3, and supporting the box cover 3 through the support plate 5, the limiting rod 9, and the bending rod 10 to keep it stable after opening;

[0031] When closing the seed box 1, press the box cover 3 downward. The limiting rod 9 slides inside the sliding hole 12 of the sliding seat 11, and the support plate 5 presses the torsion spring 7 downward, covering the box cover 3 on the top of the seed box 1. Then, rotate the rotating buckle plate 15 downward and buckle it on the top of the box cover 3. When the rotating buckle plate 15 rotates to the position of the fixed clamping block 24, the connecting groove 23 of the movable clamping block 19 is squeezed by the clamping inclined surface 26 of the fixed clamping block 24 and moves until the movable clamping block 19 enters the clamping vertical groove 22, making the fixed clamping groove 25 clamped with the bottom of the clamping vertical groove 22, thereby clamping the movable clamping block 19 and the fixed clamping block 24, and mutually limiting the box cover 3 and the rotating buckle plate 15 to achieve closing;

[0032] The opening of the box cover 3 is operated by pressing the movable clamping block 19, and the closing of the box cover 3 is automatically achieved by the extrusion of the movable clamping block 19. The overall operation is simple and convenient, saving time and effort.
