[0041] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0042] See attached Figure 1-5 , an internally reinforced hollow panel, comprising a hollow panel body, side strips 3, reinforcing rods 2 and a synchronous frame 4.
[0043] The hollow plate body includes two parallel panels 11, ribs 12 vertically arranged between the two panels 11 and connecting the two panels 11 as a whole, the ribs 12 are spaced apart along the width or length direction of the panels 11, and adjacent ribs 12 and the two panels 11 are enclosed to form a hollow cavity 13 with openings at both ends. The panels 11, ribs 12 and hollow cavity 13 are integrally formed in an extrusion process.
[0044] The side strips 3 are provided in a pair and are symmetrically distributed on both sides of the hollow plate body. The side strips 3 are fixedly connected to the hollow plate body and are perpendicular to the ribs 12 . A through hole 33 is opened on the side strips 3 , and the through hole 33 is connected to the hollow cavity 13 .
[0045] There are more than two reinforcing rods 2, and the number can be increased or decreased according to actual needs. The reinforcing rods 2 are solid structures or hollow structures. The reinforcing rods 2 pass through the hollow cavity 13 of the hollow plate body and the through holes 33 of the side strips 3 on both sides. The ends of the reinforcing rods 2 exposed from the through holes 33 are provided with positioning grooves 21 around the circumference.
[0046] A synchronous frame 4 is detachably fixed to the outside of each side strip 3 through a buckle 31. The synchronous frame 4 is an annular rectangular shape. The upper and lower rods of the synchronous frame 4 extend along the length direction of the side strip 3. The upper and lower rods of the synchronous frame 4 are embedded in the positioning groove 21 of the reinforcing rod 2 on the side facing the hollow cavity 13, and positioning protrusions 41 are respectively provided on both sides of the reinforcing rod 2 in the horizontal direction. The positioning protrusion 41 is elastic. When a horizontal external force is applied to the end of the reinforcing rod 2, the upper positioning protrusion 41 can be squeezed open, thereby realizing the horizontal displacement of the reinforcing rod 2.
[0047] In this embodiment, the upper and lower rods of the synchronous frame 4 are respectively provided with notches 42 extending toward the positioning protrusions 41, so that the thickness of the upper and lower rods at the positioning protrusions 41 is reduced. In other embodiments, the synchronous frame 4 itself is elastic, or the rod sections are connected by elastic positioning protrusions 41. When a horizontal external force is applied to the end of the reinforcing rod 2, the positioning protrusions 41 deform into the notches 42, and at the same time, the upper and lower rods are deformed outward.
[0048] In this embodiment, buckles 31 are distributed at intervals along the length direction on the upper and lower edges of each side bar 3, and the buckles 31 buckle and fix the upper and lower rods of the synchronous frame 4. The drawings only show a small section of the hollow plate body, and the positions of the reinforcing rod 2 and the synchronous frame 4 can be adjusted according to the concentrated position of the cargo load, and the buckles 31 distributed at intervals along the length direction can adapt to the position adjustment of the synchronous frame 4.
[0049] In this embodiment, the cross section of the side strip 3 is a side-mounted U-shaped structure, and the end of the hollow plate body is embedded in the U-shaped opening 32 of the side strip 3 and hot-pressed with the upper and lower side walls of the U-shaped opening 32. After adopting this structure, there is a height difference between the panel 11 and the side strip 3. In order to improve the appearance or material strength, the panel 11 is hot-pressed with reinforcing plates 14 between the side strips 3 on both sides. The reinforcing plates 14 can be made of the same material as the panel 11, or can be made of other materials, such as wear-resistant materials.
[0050] In actual application, when the position of the originally installed reinforcement rod 2 needs to be adjusted, refer to Figure 1 , it is necessary to unlock the synchronous frame 4 on one side. First, the middle parts of the upper and lower rods are clamped toward each other, and the upper and lower rods are pulled outward after being separated from the buckle 31 in the middle of the side strip 3 (to prevent them from falling into the corresponding buckle 31 again after being reset). Then, the middle parts of the upper and lower rods are pulled apart in the opposite direction, and the upper and lower rods are pulled outward after being separated from the positioning groove 21 of the reinforcing rod 2 (to prevent them from falling into the positioning groove 21 again after being reset). Finally, the synchronous frame 4 is pulled horizontally to separate its end from the buckle 31 at the end of the side strip 3, so that the synchronous frame 4 and the reinforcing rod 2 can be separated. The synchronous frame 4 on the other side does not need to be separated from the reinforcing rod 2. It is only necessary to pull the reinforcing rod 2 out of the hollow cavity 13, release the horizontal constraint of the rib plate 12 on the reinforcing rod 2, and then apply a horizontal force to the reinforcing rod 2 to shift it, and then remove it into the corresponding hollow cavity 13, and lock the synchronous frame 4.
