[0083] Alternatively, if Figure 3 As shown, the first main rib plate 111, the second main rib plate 112, the first cover plate 120, the second cover plate 130, the first bending plate 140 and the second bending plate 150 form a box structure 180. The box structure 180 has a cavity. This design can avoid material waste and ensure the structural performance of the connecting rod structure 100.

[0084] In the technical solution defined in the present utility model, a first bending plate 140 and a second bending plate 150 are added, and the two bending plates are used to connect the first cover plate 120 and the second cover plate 130. This design method does not need to bend the ends of the first cover plate 120 and the second cover plate 130. Compared with the design method in the related art (bending the ends of the two cover plates and connecting the two cover plates by line-to-line contact), the first bending plate 140 and the first cover plate 120, the first bending plate 140 and the second cover plate 130, the second bending plate 150 and the first cover plate 120, and the second bending plate 150 and the second cover plate 130 are all connected by surface-to-surface contact, which is beneficial to improving welding quality and connection strength, and can also reduce the difficulty of assembly, improve assembly efficiency, and reduce costs.

[0085] In some embodiments, optionally, Figure 3 As shown, the first cover plate 120 has a first end 121 and a second end 122 that are oppositely disposed along the first direction a. The first end 121 and the second end 122 are two ends of the first cover plate 120 that are oppositely disposed along the first direction a. Optionally, the first direction a is the length direction of the connecting rod structure 100. One end of the first bending plate 140 is bent toward the first end 121, and the other end of the first bending plate 140 is bent toward the third end 131.

[0086] Since the two ends of the first bending plate 140 are bent toward the first cover plate 120 and the second cover plate 130 respectively, this design can ensure that the first bending plate 140 is an arc-shaped structure. The first cover plate 120 and the second cover plate 130 are connected by the first bending plate 140 with an arc-shaped structure, and there is no need to bend the ends of the first cover plate 120 and the second cover plate 130.

[0087] In some embodiments, optionally, Figure 3 As shown, the second cover plate 130 has a third end 131 and a fourth end 132 that are arranged opposite to each other along the first direction a. The third end 131 and the fourth end 132 are two ends of the second cover plate 130 that are arranged opposite to each other along the first direction a. Optionally, the first direction a is the length direction of the connecting rod structure 100. One end of the second bending plate 150 is bent toward the second end 122, and the other end of the second bending plate 150 is bent toward the fourth end 132.

[0088] Since the two ends of the second bending plate 150 are bent toward the first cover plate 120 and the second cover plate 130 respectively, this design can ensure that the second bending plate 150 is an arc-shaped structure. The first cover plate 120 and the second cover plate 130 are connected by the arc-shaped second bending plate 150, and there is no need to bend the ends of the first cover plate 120 and the second cover plate 130.

[0089] In some embodiments, optionally, Figure 3 As shown, the first bending plate 140 has a first inner side surface 141 facing the first cover plate 120 and the second cover plate 130. In other words, the side of the first bending plate 140 facing the first cover plate 120 and the second cover plate 130 is the first inner side surface 141. Optionally, the first bending plate 140 is an arc-shaped structure, and the first inner side surface 141 is an arc-shaped surface.

[0090] The first inner side surface 141 is connected to the first cover plate 120, and the first inner side surface 141 is connected to the second cover plate 130. Since the first inner side surface 141 is connected to two cover plates (the first cover plate 120 and the second cover plate 130), this design method can ensure that the first bent plate 140 and the first cover plate 120, as well as the first bent plate 140 and the second cover plate 130 are connected in a surface-to-surface contact manner, which is beneficial to improving welding quality and connection strength.

[0091] In some embodiments, optionally, Figure 3 As shown, the second bending plate 150 has a second inner side surface 151 facing the first cover plate 120 and the second cover plate 130. In other words, the side of the second bending plate 150 facing the first cover plate 120 and the second cover plate 130 is the second inner side surface 151. Optionally, the second bending plate 150 is an arc-shaped structure, and the second inner side surface 151 is an arc-shaped surface.

[0092] The second inner side surface 151 is connected to the first cover plate 120, and the second inner side surface 151 is connected to the second cover plate 130. Since the second inner side surface 151 is connected to two cover plates (the first cover plate 120 and the second cover plate 130), this design can ensure that the second bent plate 150 and the first cover plate 120, as well as the second bent plate 150 and the second cover plate 130 are connected in a surface-to-surface contact manner, which is beneficial to improving welding quality and connection strength.

[0093] In some embodiments, optionally, the first inner side surface 141 is connected to the side of the first cover plate 120 facing away from the second cover plate 130, and the first inner side surface 141 is connected to the side of the second cover plate 130 facing away from the first cover plate 120. This design can ensure that the first bent plate 140 and the first cover plate 120, as well as the first bent plate 140 and the second cover plate 130 are connected in a surface-to-surface contact manner, which is conducive to improving welding quality and connection strength.

[0094] In some embodiments, optionally, the second inner side surface 151 is connected to the side of the first cover plate 120 facing away from the second cover plate 130, and the second inner side surface 151 is connected to the side of the second cover plate 130 facing away from the first cover plate 120. This design can ensure that the first bent plate 140 and the first cover plate 120, as well as the first bent plate 140 and the second cover plate 130 are connected in a surface-to-surface contact manner, which is conducive to improving welding quality and connection strength.

[0095] In some embodiments, optionally, Figure 3 As shown, the connecting rod structure 100 further includes at least one connecting plate 161. Specifically, the connecting plate 161 is disposed between the first main rib plate 111 and the second main rib plate 112. The connecting plate 161 is disposed between the first cover plate 120 and the second cover plate 130. The connecting plate 161 is disposed between the first bending plate 140 and the second bending plate 150. The connecting plate 161 is used to connect the first main rib plate 111 and the second main rib plate 112.

[0096] Before the staff installs the first cover plate 120 and the second cover plate 130, the relative position between the first main rib plate 111 and the second main rib plate 112 is fixed by the connecting plate 161, so that there is a preset gap between the first main rib plate 111 and the second main rib plate 112, which is convenient for welding the two cover plates in subsequent work and is beneficial to improving the welding quality, thereby improving the connection strength between the two cover plates and the two main rib plates.

[0097] It should be emphasized that the connecting plate 161 is also called a transverse rib plate, which is used to connect the first main rib plate 111 and the second main rib plate 112 on the one hand, and plays a role in structural reinforcement on the other hand, which is conducive to improving the structural strength of the connecting rod structure 100.
