[0031] Such as Figures 1 to 5As shown in the figure, when the thin-walled closed column 1 is connected to the bracket 2, if the connecting piece 3 penetrates through the entire thin-walled closed column 1, when it is locked, it will generate an opposite squeezing force on the two opposite side walls of the thin-walled closed column 1, resulting in the deformation of the thin-walled closed column 1, and making the two opposite side walls tend to approach each other. The connecting piece 3 and the bracket 2 can never reach the locked state, resulting in an unstable connection between the bracket 2 and the thin-walled closed column 1, posing a safety hazard. To solve the above problems, this embodiment provides a connection structure between a thin-walled closed column and a bracket, including a thin-walled closed column 1, a bracket 2, and a connecting piece 3. A connection hole 11 and an avoidance hole 12 are provided on the side wall of the thin-walled closed column 1; the connecting piece 3 can enter the interior of the thin-walled closed column 1 through the avoidance hole 12 and pass through the connection hole 11 to be connected to the bracket 2, so that the bracket 2 is only connected to the single-side side wall of the thin-walled closed column 1. The connecting piece 3 can lock the thin-walled closed column 1 and the bracket 2, improving the connection stability between the thin-walled closed column 1 and the bracket 2, avoiding the deformation of the thin-walled closed column 1 due to extrusion, and compared with the welding connection method, it not only has the advantages of being easy to assemble and disassemble, high flexibility, and low requirements for the working environment, but also can avoid the deformation of the thin-walled closed column 1 and the bracket 2 during the welding process, which is beneficial to improving the quality of the shelf.
[0032] Among them, the thin-walled closed column 1 is a column with a wall thickness not greater than 6 mm and circumferentially closed, which has high structural strength, saves materials, and has low production costs. In this embodiment, the thin-walled closed column 1 is formed by enclosing four side walls, with a regular shape and flat side walls, which is convenient for connecting with the bracket 2; the four sides of the thin-walled closed column 1 are closed. Compared with the open column, the thin-walled closed column 1 in this embodiment has better anti-torsion performance and bending performance, and its comprehensive load-bearing capacity is stronger; compared with the thick-walled closed column, less raw materials are required to produce the thin-walled closed column 1 in this embodiment, which has the advantages of low production cost and small weight, can save costs and is convenient for transportation.
[0033] Specifically, the connecting piece 3 includes a connecting bolt 31 and a connecting nut 32. The connecting bolt 31 is sent into the interior of the thin-walled closed column 1 through the avoidance hole 12, and sequentially passes through the connection hole 11 and the bracket 2 to be threadedly connected and locked with the connecting nut 32. The connecting nut 32 is outside the thin-walled closed column 1, which is more convenient for screwing operations. In other embodiments, the connecting piece 3 can be, but is not limited to, an insertion pin or tenon and mortise, etc., which is not limited here.
[0034] Optionally, the operator can also set the connecting bolt 31 outside the thin-walled closed column 1, sequentially pass through the bracket 2 and the thin-walled closed column 1, send the connecting nut 32 into the interior of the thin-walled closed column 1 through the avoidance hole 12, and threadedly connect it with the connecting bolt 31.
[0035] Such as Figure 3As shown, in this embodiment, an operator can use the installation tool 200 to clamp the connecting bolt 31 or the connecting nut 32, so as to send it into the interior of the thin-walled closed column 1 through the avoidance hole 12. Among them, a magnetic member can be arranged on the installation tool 200, which can adsorb the connecting bolt 31 by magnetic force. In other embodiments, the installation tool 200 can also be provided with clamping jaws to clamp the connecting bolt 31, which is not limited here.
[0036] Furthermore, as Figure 4 and Figure 5 shown, the diameter of the avoidance hole 12 is larger than that of the connecting hole 11, providing an avoidance space for the installation tool 200 to clamp the connecting bolt 31 and pass through the avoidance hole 12 into the interior of the thin-walled closed column 1, so as to facilitate the operation.
[0037] Furthermore, a plurality of connecting holes 11 are formed on the side wall of the thin-walled closed column 1, so that there can be a plurality of connection points between the bracket 2 and the thin-walled closed column 1, and the connection strength between the bracket 2 and the thin-walled closed column 1 is greater and the stability is higher. The avoidance holes 12 and the plurality of connecting holes 11 are arranged in one-to-one correspondence, so that the connecting member 3 can reach near the corresponding connecting hole 11 through each avoidance hole 12, preventing the operation difficulty from being increased due to the long distance between the avoidance hole 12 and the connecting hole 11.
[0038] In this embodiment, each avoidance hole 12 is arranged directly opposite to the corresponding connecting hole 11. After the operator uses the installation tool 200 to send the connecting bolt 31 into the interior of the thin-walled closed column 1, alignment is not required, and the connecting bolt 31 can be directly inserted into the connecting hole 11, which is beneficial to improving the operation convenience and production efficiency.
[0039] In some embodiments, a plurality of connecting holes 11 are arranged at intervals in the vertical direction on the thin-walled closed column 1, and the bracket 2 can be selectively installed in any connecting hole 11. Combining the characteristics that the connecting nut 32 and the connecting bolt 31 are convenient for disassembly and assembly, it is possible to facilitate the adjustment of the height of the bracket 2 and improve the utilization rate of the bracket 2 and the thin-walled closed column 1 and the versatility of the shelf.
[0040] As Figures 1 to 3 shown, the bracket 2 includes a first U-shaped member 21 and a second U-shaped member 22. The opening directions of the first U-shaped member 21 and the second U-shaped member 22 are opposite and are connected in a cross shape. The first U-shaped member 21 is used to connect with the thin-walled closed column 1, and the U-shaped opening of the first U-shaped member 21 can be clamped with the thin-walled closed column 1, which helps to position between the bracket 2 and the thin-walled closed column 1 and is beneficial to improving the connection strength. The second U-shaped member 22 is used for load bearing, and the U-shaped structure has better anti-torsion performance and anti-bending performance, which is beneficial to improving the bearing capacity of the bracket 2.
[0041] For the convenience of load-bearing, in some embodiments, the length of the second U-shaped member 22 is greater than that of the first U-shaped member 21, so that the second U-shaped member 22 has a larger bearing area, which is convenient for connecting with the load-bearing beam 100 or the pallet.
[0042] Wherein, the first U-shaped member 21 and the second U-shaped member 22 are connected by welding, which has high connection strength and a smooth surface, avoiding interference with the thin-walled closed column 1 by using connecting parts such as bolts.
[0043] This embodiment also provides a shelf, including a load-bearing beam 100 and the connection structure between the thin-walled closed column and the bracket in any of the above embodiments. A plurality of thin-walled closed columns 1 are arranged upright at intervals and are all connected to the ground. The brackets 2 are used to bear the load-bearing beam 100. A plurality of load-bearing beams 100 are connected to the corresponding thin-walled closed columns 1 through the brackets 2 to form a shelf, and goods can be carried on the load-bearing beam 100. By applying the above connection structure between the thin-walled closed column and the bracket, the shelf can be easily assembled, has high stability and better load-bearing capacity.
[0044] Similarly, the load-bearing beam 100 is of U-shaped structure, which has better anti-torsion performance and bending performance and high load-bearing capacity. In this embodiment, the load-bearing beam 100 is threadedly connected to the second U-shaped member 22 by bolts, with stable connection and convenient disassembly and assembly.
[0045] Optionally, the connection mode between the second U-shaped member 22 and the load-bearing beam 100 includes but is not limited to clamping or plugging, etc., which is not limited herein.
[0046] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
