Abstract
Description
Technical Field
[0001] The utility model relates to a shelf structure, in particular to a support bar and a shelf for improving bearing capacity. Background Technique
[0002] In the warehousing industry, with the popularization of light shuttle cars, bin storage is becoming more and more widespread. The most common storage method for bin storage is to add longitudinal support bars on the cross beam, and the bins are directly supported by the support bars. The structures of the support bars are basically two types at present. One is to snap the support bar into the inside of the cross beam (such as Figure 1 ). The advantage of this kind of support bar is that it has strong bearing capacity and is easy to install. The support bar can be directly snapped onto the cross beam. The disadvantage is that the bayonet of the support bar is complex and requires mold making. At the same time, special slots also need to be opened on the cross beam to match the bayonet of the support bar, resulting in high processing difficulty and low efficiency of the cross beam. The other type of support bar is to cut off the four corners of a flat plate, bend it downward on all four sides, and then directly buckle it on the cross beam (such as Figure 2 ), and it is fixed with self-tapping screws. The advantage is that the production of the support bar is relatively simple and no additional process is required for the production of the cross beam. However, since the contact between the support bar and the cross beam is flat plate stress, the bearing capacity of this support bar is poor. Content of the Utility Model
[0003] Purpose of the utility model: Aiming at the above disadvantages, the utility model provides a support bar with simple processing, convenient installation and improved bearing capacity.
[0004] The utility model also provides a shelf using the above support bar.
[0005] Technical solution: To solve the above problems, the utility model adopts a support bar for improving bearing capacity, which includes a support main body, a lapping part and a limiting part located at both ends of the support main body. The support main body includes a first bearing surface and first reinforcing surfaces bent in the same direction on both sides of the first bearing surface. The lapping part includes a second bearing surface, second reinforcing surfaces bent in the same direction on both sides of the second bearing surface, and two supporting surfaces bent inward in the same direction by the two second reinforcing surfaces. The supporting surfaces are used for lapping on the cross beam. One end of the second bearing surface is fixedly connected to the first bearing surface and is in the same plane. The bending directions of the first reinforcing surface and the second reinforcing surface are the same. The first reinforcing surface and the second reinforcing surface on the same side are fixedly connected and are in the same plane. The other end of the second bearing surface is bent along the extending direction of the second reinforcing surface to obtain the limiting part. The side end of the first reinforcing surface and the limiting part are clamped on both sides of the cross beam.
[0006] Further, the ends of the two supporting surfaces are in contact with each other, and the cross section of the lapping part is rectangular.
[0007] Further, the limiting part is provided with through holes for screw connection.
[0008] Further, the support main body is a C-shaped beam.
[0009] The present utility model also adopts a shelf, which includes two parallel crossbeams and a plurality of the above-mentioned support bars. The support surfaces at both ends of the support bar are respectively lapped on the two crossbeams.
[0010] Furthermore, the limiting part of the support bar is fixed to the side surface of the crossbeam by self-tapping screws.
[0011] Beneficial effects: Compared with the prior art, the present utility model has the advantages that the position where the support bar contacts the crossbeam is specially bent, so that the load-bearing capacity of the support bar is greatly enhanced. The support bar is made by a mold, with simple processing and manufacturing, and can be mass-produced, thus having high production efficiency. The crossbeam connected to the support bar does not need to be additionally grooved or other processing procedures added, and the component applicability and matching are strong. After the support bar is buckled on the crossbeam, it is limited and fixed by self-tapping screws, which is convenient for installation and has low requirements for installation accuracy. The component has strong load-bearing capacity, and a thinner component can meet the use requirements, with high cost performance. It has a wide range of applications and can be applied to the vast majority of bin shelf structures. Description of the Drawings

[0019] Such as Figures 3 to 5As shown in the figure, in this embodiment, a stay bar for improving the bearing capacity includes a support main body 1, a lapping part 2 and a limiting part 3 located at both ends of the support main body 1. The support main body 1 includes a first bearing surface 11 and first reinforcing surfaces 12 formed by bending in the same direction on both sides of the first bearing surface 11. The lapping part 2 includes a second bearing surface 21, second reinforcing surfaces 22 formed by bending in the same direction on both sides of the second bearing surface 21, and two supporting surfaces 23 formed by bending the two second reinforcing surfaces 22 inward in the same direction. The supporting surfaces 23 are used for lapping on the cross beam 4. One end of the second bearing surface 21 is fixedly connected to the first bearing surface 11 and is in the same plane. The bending directions of the first reinforcing surface 12 and the second reinforcing surface 22 are the same. The first reinforcing surface 12 and the second reinforcing surface 22 on the same side are fixedly connected and are in the same plane. The other end of the second bearing surface 21 is bent along the extending direction of the second reinforcing surface 22 to obtain the limiting part 3. The side end of the first reinforcing surface 12 and the limiting part 3 are clamped on both sides of the cross beam 4. The support main body 1 is a C-shaped beam. The ends of the two supporting surfaces 23 are in contact with each other, and the cross section of the lapping part 2 is rectangular. The limiting part 3 is provided with through holes 31 for screw connection.
[0020] Through finite element analysis and experiments, it is found that the position where the stay bar is most poorly stressed is the position where the cross beam 4 contacts the stay bar, that is, the position of the cut of the stay bar. By bending the side surface of the stay bar inward, a structure in the shape of a rectangular tube is formed. The original flat surface contact with the cross beam 4 becomes a rectangular tube contact with the cross beam 4, and the cross-sectional height of the contact surface increases several times. As Figure 5 shown, since the rectangular tube is much more stress-resistant than the flat plate, the bearing capacity of the stay bar is greatly improved.
[0021] As Figure 6 and Figure 7 shown, the shelf includes two parallel cross beams 4. The stay bars are evenly installed on the cross beams 4. The supporting surfaces 23 at both ends of the stay bars are respectively lapped on the two cross beams 4, and the limiting part 3 is fixedly connected to the side surface of the cross beam 4 by self-tapping screws 5.
