[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a lower hanging beam back rib, including a back rib body 110, a vertical connector 120, and a horizontal base 130. The top of the vertical connector 120 is fixedly installed with the horizontal base 130, forming an L-shaped reinforcement. The vertical connector 120 is symmetrically fixed on both sides of the back rib body 110 by a 121-pin. A tie rod 140 is installed on the two symmetrical vertical connectors 120. Nuts 141 are threaded on both ends of the tie rod 140. Multiple reinforcements are fixedly installed on both sides of the back rib body 110, and the multiple reinforcements on each side are equidistantly arranged. The back rib body 110 has a first mounting groove on both sides that matches the 121-pin. The tie rod 140 is located below the back rib body 110. Both the vertical connector 120 and the horizontal base 130 are 50*30 square tubes. A 121-pin is installed on the horizontal base 130 for fixed connection with the support.

[0021] In some specific implementations, the vertical connector 120 is provided with a first circular hole that matches the tie rod 140. The tie rod 140 slides through the first circular hole. A reinforcing cap 142 is fixedly installed on one side of the nut 141. The reinforcing cap 142 is threaded onto the tie rod 140. The reinforcing cap 142 is also hexagonal, and its length is greater than that of the nut 141. The reinforcing cap 142 improves the stability when the nut 141 is fixed. Two washers 143 are symmetrically slidably installed on the tie rod 140. The washers 143 are located between the two nuts 141. The diameter of the washers 143 is greater than that of the first circular hole. The washers 143 further improve the stability after the nut 141 is fixed.

[0022] Please see Figure 3 and Figure 4The back rib body 110 is U-shaped. Multiple reinforcing blocks 150 are slidably installed on the inner wall of the back rib body 110. The two sides of the reinforcing blocks 150 are fixedly connected to the back rib body 110 by bolts 151. The two sides of the reinforcing blocks 150 are provided with threaded grooves that match the bolts 151. The two sides of the back rib body 110 are provided with second round holes that match the bolts 151. Multiple first mounting grooves and multiple second round holes are alternately arranged on both sides of the back rib body 110.

[0023] In some specific implementation schemes, the inner walls of the back rib body 110 are provided with sliding grooves that match the reinforcing block 150. The reinforcing block 150 is slidably connected to the inner wall of the sliding groove. The sliding groove corresponds one-to-one with the second round hole. The setting of the sliding groove improves the limiting position of the reinforcing block 150 during installation, thereby improving stability.

[0024] In some specific implementation schemes, a weight-reducing hole is provided at the center of the reinforcing block 150, and the four corners of the reinforcing block 150 are inclined. The inclined corners of the reinforcing block 150 facilitate quick installation into the slide groove. At the same time, the weight-reducing hole reduces the weight of the reinforcing block 150 and reduces the pressure on the back rib body 110.

[0025] Working principle: When in use, the reinforcement component is fixed to both sides of the back rib body 110 by the seven-pin 121. Then, according to the weight support requirements, the reinforcement block 150 is inserted into the slide groove. The reinforcement block 150 and the back rib body 110 are then fixed by the bolt 151. The tie rod 140 is then passed through the first round hole and fixed by the nut 141. Finally, the back rib body 110 and the reinforcement component are installed at the support.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
