Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a pipe connection structure. Background Technology

[0002] Traditional pipe connection structures mostly use welding and plug-in methods. Firstly, the welding process is relatively complicated and costly. Secondly, the plug-in method is prone to shaking during use, which can lead to structural instability. For example, Chinese patent document CN107671817A discloses a storage rack, which is characterized by including a storage platform and four uprights. The storage platform is rectangular, and the four uprights are respectively located at the bottom of the four corners of the storage platform. The upper surface of the four corners of the storage platform is provided with plug-in parts corresponding to the uprights, and the plug-in parts fit into the pipe holes of the uprights.

[0003] In the above scheme, the connection between pipes is achieved by plugging, which often results in shaking during use. Summary of the Invention

[0004] The purpose of this invention is to provide a more stable pipe connection structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pipe connection structure, characterized in that it includes a first connecting pipe, a second connecting pipe, and a connector. One end of the first connecting pipe is connected to one end of the second connecting pipe via the connector. One end of the first connecting pipe forms a first half-pipe adapted to the outer periphery of one end of the connector. One end of the second connecting pipe forms a second half-pipe adapted to the outer periphery of the other end of the connector. The first half-pipe, the second half-pipe, and the connector all have through holes for fasteners to pass through. After installation, the connector is located between the first half-pipe and the second half-pipe. Fasteners pass through the through holes of the first half-pipe, the second half-pipe, and the connector to connect the first half-pipe, the second half-pipe, and the connector together.

[0007] By adopting the above technical solution, the first connecting pipe and the second connecting pipe are connected by a connector; the first half pipe and the second half pipe are adapted to the outer periphery of the connector and fixed by perforation and fasteners. The connector, as an intermediate layer, can distribute axial and radial forces and reduce the risk of pipe deformation, thereby ensuring the stability of the first connecting pipe and the second connecting pipe after installation.

[0008] The fasteners include bolts and nuts, with the bolts passing through holes in the first half-pipe, the second half-pipe, and the connector, and being locked in place by the nuts.

[0009] By adopting the above technical solution and using bolts and nuts as fasteners, it is convenient to disassemble and assemble the first half-pipe, the second half-pipe, and the connecting parts. Moreover, standard bolts and nuts are universal parts, with low procurement costs and a stable supply chain.

[0010] The first and second half-pipes have circular cross-sections, the connector has a circular cross-section, and the outer diameter of the connector is equal to or greater than the inner diameter of the first and second connecting pipes.

[0011] By adopting the above technical solution, the circular cross-section provides uniform contact, which can avoid the stress concentration problem at the corners of square or polygonal structures. The outer diameter of the connector is equal to or greater than the inner diameter of the pipe, which can ensure a tighter connection between the first and second connecting pipes and increase its connection stability.

[0012] It also includes a third connecting pipe, one end of which forms a third half-tube. The inner surface of the third half-tube is adapted to the outer periphery of the first half-tube or the second half-tube. During installation, it can be installed on the outer periphery of the first half-tube or the second half-tube after the first connecting pipe and the second connecting pipe are connected.

[0013] By adopting the above technical solution, a third half-tube is formed on the third connecting tube, and the third half-tube can be adapted to the outer periphery of the first half-tube or the second half-tube. Therefore, without changing the original connection structure, the function can be expanded by superimposing the third connecting tube, and the third connecting tube can be added or removed at any time according to the needs, and the frame shape can be flexibly adjusted.

[0014] The first connecting pipe, the second connecting pipe, and the third connecting pipe are made of metal.

[0015] By adopting the above technical solution, the metal material has high tensile strength and is not easily bent or broken when supporting heavy objects.

[0016] A storage rack, characterized in that it includes a tube connection structure, through which the storage rack is assembled and supported.

[0017] The shelf includes a base and a placement surface. The tube connection structure can be connected between the base and the placement surface. Specifically, the other end of the first connecting tube is connected to the base, and the other end of the second connecting rod is connected to the placement surface. The first connecting tube and the second connecting tube are then connected and fixed by the cooperation of the first half tube, the second half tube and the connecting piece.

[0018] By adopting the above technical solution, the other end of the first connecting tube is fixed to the base, and the other end of the second connecting tube is fixed to the tabletop. The first connecting tube and the second connecting tube are connected and fixed by the cooperation of the first half tube, the second half tube and the connector, which can facilitate the assembly of the shelf.

[0019] There can be multiple first connecting pipes and second connecting pipes.

[0020] By adopting the above technical solution, multiple first connecting pipes and second connecting pipes can increase the storage function of the shelf to hold more items. Attached Figure Description

The first connecting pipe 1, the second connecting pipe 2, and the third connecting pipe 3 are made of metal, specifically stainless steel or other metal materials. One end of the first connecting pipe 1 is connected to one end of the second connecting pipe 2 via the connector 4. One end of the first connecting pipe 1 forms a first half-pipe 11 that fits the outer circumference of one end of the connector 4. One end of the second connecting pipe 2 forms a second half-pipe 21 that fits the outer circumference of the other end of the connector 4. The first half-pipe 11, the second half-pipe 21, and the connector 4 all have through holes 6 for fasteners 5 to pass through. The fasteners 5 include bolts 51 and nuts 52. After installation, the connector 4 is located between the first half-pipe 11 and the second half-pipe. Between 21, bolt 51 passes through the through hole 6 of the first half tube 11, the second half tube 21 and the connector 4 and is locked by nut 52 to connect the first half tube 11, the second half tube 21 and the connector 4 together. One end of the third connecting tube 3 forms a third half tube 31. The inner side of the third half tube 31 is adapted to the outer circumference of the first half tube 11 or the second half tube 21. During installation, it can be installed on the outer circumference of the first half tube 11 or the second half tube 21 after the first connecting tube 1 and the second connecting tube 2 are connected.

[0031] The system also includes a shelf 7 assembled using the aforementioned tube connection structure. The shelf 7 includes a base 71 and a placement surface 72.
