In addition, the supporting frame 23 includes a first frame 231 disposed along the horizontal direction, a second frame 232 disposed along the vertical direction, and a connecting shaft 234 passing through the first frame 231 in the vertical direction, the upper end of the first rod 31 is bent toward the connecting shaft 234 to form a fourth connecting body and is rotatably connected with the connecting shaft 234, and the fourth connecting body and the first connecting body 331 are disposed in a reverse direction. In the embodiment, the fourth connecting body and the first connecting body 331 are both bent from the rod body one 31 and face opposite directions, and compared to a normal connecting rod without bending, the connecting rod structure 3 in the embodiment can be driven more easily according to the lever principle, and the opening efficiency is improved. The connecting shaft 23 longitudinally penetrates through the first frame 231, and the end part of the connecting shaft is rotatably connected with the fourth connecting body, the fourth connecting body is not directly connected with the top plate 21 or the side plate 22, but is used as a bearing body through the connecting shaft 23, so that in the actual application process, the connecting shaft 23 is driven by the connecting rod structure 3, the supporting frame 23 is driven through the connecting shaft 23, the driving force is diffused, the stress point is not concentrated, and the stability of the driving process is guaranteed.

In other embodiments, as shown in fig. 4, the link structure 3 further includes at least one pair of second rods 34 disposed opposite to each other, the upper ends of the second rods 34 are bent along the direction of the first connecting body 331 to be rotatably connected with the connecting shaft 234, the lower ends of the second rods are bent along the direction of the fourth connecting body to be rotatably connected with the driving shaft 12, and the first rods 31 and the second rods 34 move synchronously and are located on different axes. Specifically, in this embodiment, the link structure 3 further includes a pair of oppositely disposed second rod bodies 34, the upper end of the same second rod body 34 is bent to be rotatably connected with the connecting shaft 234, and the lower end of the same second rod body is bent to be rotatably connected with the driving shaft 12, so that the hatch cover structure 3 is driven by the pair of first rod bodies 31 and the pair of second rod bodies 34 together, on one hand, the whole driving stability is good, and on the other hand, a sufficient driving force is ensured. Of course, in other embodiments, two or more pairs of second rods 34 may be provided, or the second rods 34 may not be bent, and both ends of the second rods are directly connected to the driving shaft 12 and the connecting shaft 234, which also has the above-mentioned function.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
