[0002] Currently, many shelves used to hold various items (such as shelves for washbasins or bulging shelves) often involve the connection of profile tubes. Profile tubes are typically long strips of metal materials like iron, aluminum, or steel, extruded through a die. During installation, pairs of profile tubes are usually welded together and then assembled according to requirements to form the desired shape. After leaving the factory, these shelves are already pre-assembled and cannot be disassembled. During transportation, these shelves may deform or bend, increasing the stress and cost of transport.

[0003] In existing technologies, connectors exist, allowing the profile tube and connector to be fixed together with bolts. For example, bolt holes are provided in the connector, a top bolt is installed at the top of the profile tube, and then the top bolt is connected to the bolt holes in the connector to connect the profile tube and connector. The required shape can then be assembled. However, when connecting the profile tube and connector, the profile tube is often misaligned during installation, resulting in uneven ends of the profile tube after the top bolt is tightened, leading to poor overall structural stability.

[0006] Furthermore, one end of the insertion rod is fixedly installed on the top wall of the cavity; the other end of the insertion rod extends out from the cavity.

[0007] Furthermore, the at least two insertion rods include a first insertion rod, a second insertion rod, a third insertion rod, a fourth insertion rod, and a fifth insertion rod. The first insertion rod and the second insertion rod extend in the same direction, and the third insertion rod and the fourth insertion rod extend in the same direction. The first insertion rod, the third insertion rod, and the fifth insertion rod are arranged perpendicular to each other in pairs.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0020] Please refer to Figures 1 to 3 A profile pipe connecting piece, comprising a connecting body 1 and at least two insertion rods 2, the connecting body 1 is provided with at least two assembly surfaces 3, the assembly surface 3 is fixedly connected with the insertion rod 2, and the insertion rod 2 is used for being fixedly connected to the mounting end of the profile pipe.

[0021] In the technical scheme, the two ends of the profile pipe are both mounting ends; the connecting body 1 is fixedly connected with the insertion rod 2, the insertion rod 2 extends into the inner cavity of the mounting end of the profile pipe until the mounting end abuts against the assembly surface 3, then the insertion rod 2 and the mounting end are fixed, so that the profile pipe and the connecting piece are connected, the other end of the profile pipe is also inserted into another connecting piece, and then a plurality of profile pipes are spliced according to requirements, so that the installation is convenient, the stress at the connecting position of the profile pipe and the connecting piece is enhanced, dislocation is not easy to occur, and it is not necessary to fix the profile pipe and the connecting piece by mounting bolts at the top end of the profile pipe, thereby avoiding the defects that in the prior art, the top end bolts can be connected only after the top end bolts are mounted at the top end of the profile pipe, the stress at the connecting position of the profile pipe and the connecting piece is reduced, and the bolts are easy to loosen and fall off. The user can realize the installation by himself, even if the user installs incorrectly, the user can also disassemble and reinstall, the cost performance is high, and good product experience is provided for the user.

[0022] It is worth noting that, as shown in Figure 1 and Figure 2 , the number of insertion rods 2 is used for the number of profile pipes in different products, the user can select the connecting piece with different numbers of insertion rods 2 according to the requirements of different types of products, which is not limited herein; and the insertion rod 2 can be fixedly installed in multiple directions of the connecting body 1, which is also not limited herein.

[0023] It should be noted that the profile tube in this embodiment is a commonly used type and specification in the market. It is hollow and has an inner cavity. Both ends are installation ends. However, the type of profile tube in this embodiment is not limited. It can be a round tube or a square tube.

[0024] To reduce the weight of the connectors, by Figure 1 and Figure 3 As shown, one of the mounting surfaces 3 is recessed towards the center of the connecting body 1, forming a cavity 11. This cavity 11 communicates with the other mounting surface 3. The cavity 11 increases the bending strength. When a user wants to install a light fixture (such as an LED light strip) on the shelf supporting the washbasin, the LED light strip can be passed through the cavity 11 of the mounting surface 3 in advance on the connector until it emerges from the other mounting surface 3, thus stabilizing the LED light strip and allowing it to be used for lighting without occupying space. The specific embodiment of the insert rod 2 in the cavity 11 is described in [the following text is incomplete and requires further context]. Figure 3 As shown, one end of the insertion rod 2 in the cavity 11 is fixedly installed on the top wall 111 of the cavity 11; the other end of the insertion rod 2 extends out from the cavity 11 and is used to connect to the mounting end. In this embodiment, the insertion rod 2 can be snapped into the gap between the wall of the cavity 11 and the wall of the mounting end to increase stability, and then the mounting end and the insertion rod 2 are fixed together.

[0025] Furthermore, the at least two insertion rods 2 include a first insertion rod, a second insertion rod, a third insertion rod, a fourth insertion rod, and a fifth insertion rod. The first and second insertion rods extend in the same direction, and the third and fourth insertion rods extend in the same direction. The first, third, and fifth insertion rods are arranged perpendicularly to each other in pairs. In this embodiment, the first and second insertion rods extend in the same direction, meaning they can extend in the same direction during installation, suitable for situations requiring parallel arrangement. The third and fourth insertion rods extend in the same direction, which also applies to another set of parallel arrangements. The first, third, and fifth insertion rods are arranged perpendicularly to each other in pairs, ensuring the stability and accuracy of the connector in different directions. The number of insertion rods 2 is not limited here.

[0026] To ensure structural stability and prevent it from falling off, bolt connection holes are provided at the mounting end in this embodiment so that the mounting end can be fixedly connected to the insertion rod 2. However, the method of fixing the mounting end to the insertion rod 2 is not limited here.

[0027] Specifically, by Figure 1 and Figure 2As shown, the end of the insertion rod 2 away from the connecting body 1 is provided with a bolt fixing hole 21. The bolt fixing hole 21 is correspondingly provided with the bolt connection hole at the mounting end. Bolts are provided to sequentially connect and fix the bolt connection hole and the bolt fixing hole 21, making the profile tube less likely to fall off. During disassembly, only the bolts need to be unscrewed to pull out the profile tube and separate the profile tube from the insertion rod 2. Specific embodiments are described below. Figure 1 As shown.

[0028] Optionally, by Figures 1 to 3 As shown, the connecting body 1 is a spherical structural component with at least one side being a rounded transition surface, which can avoid the fragile surface caused by sharp corners or right angle transitions, improve processing accuracy and surface smoothness, and make it less likely to injure the user.

[0029] The assembly surface 3 is defined on the outer surface area of ​​the spherical structural member, and at least two of the assembly surfaces 3 are perpendicular to each other. The spherical structural member connecting the body provides multi-directional connection possibilities, and the design of the mutually perpendicular assembly surfaces 3 enhances the stability of the connection. By setting the assembly surface 3 on the outer surface area of ​​the spherical structural member, stable connection of the profile tube in multiple directions can be ensured, thereby solving the connection stability problem of the profile tube connector.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
