It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it 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 directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0020] As Figures 1-3As shown in the figure, a unlocking device for a turnover box includes a mounting frame 1, a flipping mechanism 2, a flipping plate 3, a rotary power component 4, a clamping plate 5, a pull rod cylinder 6 and a pull rod 7. A flipping mechanism 2 is installed on one side of the mounting frame 1. The flipping mechanism 2 drives the flipping plate 3 to flip. The flipping plate 3 is L-shaped. A rotary power component 4 is installed inside the flipping plate 3. The output shaft of the rotary power component 4 is installed with the clamping plate 5. The rotary power component 4 drives the clamping plate 5 to rotate so as to clamp the handle 8 of the turnover box. A pull rod cylinder 6 is installed on the other side of the mounting frame 1. The output shaft of the pull rod cylinder 6 is installed with the pull rod 7. The pull rod 7 extends inward. The pull rod cylinder 6 drives the pull rod 7 to move so as to pull open the bolt 9 of the turnover box.

[0021] As shown in Figure 4 Figure, one side plate A of the turnover box is shown. Actually, the turnover box is composed of 4 side plates A and a base. The bottom of the side plate is rotatably connected to the base. A locking mechanism is provided above two opposite side plates. The locking mechanism of the turnover box mainly includes a handle 8 and a bolt 9. The handle 8 and the bolt 9 are respectively installed on the side plate. The handle 8 is located above the bolt. The bolt 9 can be elastically installed on the side plate by means of an elastic member such as a spring. The handle 8 is rotatable on the side plate. A catch is provided on the outside of the handle 8. The handle 8 is provided with a slot corresponding to the position of the bolt 9. When the upper end of the bolt 9 is inserted into the slot, the handle 8 cannot rotate. When the bolt 9 moves downward and disengages from the slot, the handle 8 can rotate to drive the catch to rotate to realize whether to clamp the other side plate.

[0022] Specifically, the mounting frame 1 includes a cross plate 10 and a vertical plate 11. The vertical plate 11 is fixedly installed on the side of the cross plate 10. The cross plate 10 and the vertical plate 11 are perpendicular to each other. The flipping mechanism 2 is installed on the side of the vertical plate 11. The pull rod cylinder 6 is installed on the other side of the cross plate 10.

[0023] Specifically, the flipping mechanism 2 includes a hydraulic cylinder 21, a main cylinder body 22, a gear set (not shown) and a rotating shaft 23. The main cylinder body 22 is fixedly installed on the side of the vertical plate 11. The hydraulic cylinder 21 is installed on the main cylinder body 22. A gear set is installed inside the main cylinder body 22. The gear set is mainly composed of a rack and a circular gear. The gear set converts the linear motion of the piston rod into the rotational motion of the rotating shaft 23. The hydraulic cylinder 21 drives the rotating shaft 23 to rotate through the gear set. The rotating shaft 23 is fixedly connected to the flipping plate 3.

[0024] Specifically, the clamping plate 5 is provided with a card slot 51. The cross-sectional dimension of the card slot 51 is larger at the lower end and smaller at the upper end to facilitate the rotation of the handle into it. In addition, the flipping center axis X1 of the flipping plate 3 and the rotation center axis Y1 of the clamping plate 5 are perpendicular to each other. The rotary power component 4 is a rotary cylinder or a servo motor, which can realize the rotation and displacement of the clamping plate 5.

[0025] Next, taking Figure 5As an example to illustrate the working principle of this solution: Use a cylinder or a servo motor or other conventional moving device to bring the turnover box closer to the turnover box unlocking device. When the turnover box unlocking device is in the position facing the turnover box locking mechanism, the pull rod cylinder 6 drives the pull rod 7 to move downward along the Z-axis. The pull rod 7 pulls out the bolt 9 of the turnover box, so that the bolt 9 no longer locks the handle. The rotary power member 4 drives the clamping plate 5 to rotate counterclockwise by 90 degrees around the axis Y1; the handle 8 enters the card slot 51 to realize clamping the handle 8 of the turnover box. The flipping mechanism 2 drives the flipping plate 3 to flip clockwise around the axis X1. The flipping plate 3 drives the rotary power member 4 to flip. The rotary power member 4 pulls the handle 8 to flip through the clamping plate 5 to realize the inward retraction of the buckle.
