[0002] With the development of global economic integration, product manufacturing is showing a trend of global collaboration, and the logistics and transportation industry is booming. Against this backdrop, the protection requirements for some precision components during logistics and transportation are becoming increasingly stringent. For example, products such as drive motors, engines, and battery packs for new energy vehicles all require the use of appropriate material racks for packaging and transportation.

[0003] In the existing technology, the connection process between the various rods of conventional material racks is complicated. In the process of production, maintenance and replacement of parts, a large number of electric and hot processes such as cutting and welding are used. For example, in the process of making material base frame, steel pipes are cut to the required length and then the pipes are welded together to form a crisscross support base frame. The operation is cumbersome and inconvenient, time-consuming and costly.

[0004] Therefore, there is a market demand for designing an assembly connector that enables the material rack to be assembled quickly and easily. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a quick assembly connector for a material rack, including a platform with an outer contour in the shape of a polygonal frustum or a frustum, an end positioning post protruding outward from the top of the platform, and a tail connection part at the bottom of the platform that connects to the end of the tube.

[0007] In some embodiments, the platform has an inner cavity in the middle that penetrates the bottom.

[0008] In some embodiments, the center line of the end positioning post is parallel to or coincides with the center line of the platform.

[0009] In some embodiments, the end positioning post has an internal threaded hole, the center line of the internal threaded hole coincides with the center line of the end positioning post, and the internal threaded hole is connected to the inner cavity.

[0010] In some embodiments, the tail connector is used for positioning and fixing with the end sleeve of the tube body by welding.

[0011] In some embodiments, the tail connection includes an outer retaining edge that expands outward from the bottom edge of the platform to form a ring for welding and fixing to the end face of the tube.

[0012] In some embodiments, the tail connection portion further includes a reinforcing edge that extends outward in the direction of the center line of the platform body based on the bottom edge, and the reinforcing edge and the outer retaining edge are integrally formed with a plurality of positioning protrusions that abut against and position with the inner wall of the tube.

[0013] In some embodiments, the frustum is in the shape of a regular quadrilateral frustum.

[0014] In some embodiments, the quick-assembly connector of the material rack is made of cast metal.

[0025] As attached Figure 1-3 As shown, a quick-assembly connector for material racks is used for assembling logistics material racks, making the fabrication and maintenance of material racks more convenient and efficient. (See attached image.) Figure 4 , 5 As shown, two quick-assembly connectors for material racks are installed at both ends of the square tube 4 to form a splicing pipe.

[0026] Align and insert the quick-assembly connector of the material rack at one end of the splicing pipe into the assembly hole on the other pipe to assemble the material rack.

[0027] As attached Figure 1-3 As shown, the material rack quick-assembly connector is cast in one piece, offering high strength and a complex integrated structure, resulting in lower mass production costs. Detailed structure is as follows:

[0028] It includes a platform 2 with a quadrangular frustum-shaped outer contour, a cylindrical end positioning post 1 protruding outward from the top of the platform 2, and a tail connector 3 located at the bottom of the platform 2. The overall shape gradually decreases in size from the tail connector 3 to the end positioning post 1, facilitating quick alignment and assembly of the tube body's assembly holes. (See attached image) Figure 5 As shown, the assembly hole is designed to match the shape of the quadrangular truncated pyramid 2 and the end positioning post 1. The assembly hole includes a square window on one side of the tube body 4 and a round hole on the other side of the tube body 4 opposite the square window. During assembly, the end positioning post 1 is inserted into the round hole, and the bottom of the quadrangular truncated pyramid 2 corresponds to the square window, effectively preventing axial rotation.

[0029] As attached Figure 1 , 2 As shown, in this embodiment, the platform 2 has an inner cavity 21 penetrating the bottom in the middle. An internally threaded hole 11 is provided on the end positioning post 1, which communicates with the inner cavity 21. The center line of the internally threaded hole 11, the center line of the end positioning post 1, and the center line of the platform 2 coincide. This results in uniform and stable force distribution and a relatively light overall weight. Furthermore, when the quick-assembly connector of the material rack is inserted into the corresponding assembly hole, a bolt can be screwed into the internally threaded hole 11 from the outside to prevent the quick-assembly connector from detaching from the assembly hole during assembly.

[0030] As attached Figure 2 , 3As shown, the tail connector 3 is used to connect to the end of the square tube 4. In this embodiment, the tail connector 3 is used to be welded and fixed after being positioned and fitted with the end sleeve of the tube 4. It includes a square outer edge 31, a square reinforcing edge 32, and four integrally formed positioning protrusions 33 between the reinforcing edge 32 and the outer edge 31. The square outer edge 31 is formed by expanding outwards around the bottom edge of the platform 2 in the bottom direction. The square reinforcing edge 32 is formed by expanding outwards around the bottom edge of the platform 2 in the center line direction. The four positioning protrusions 33 are located at the corner positions.

[0031] In this embodiment, the quick-assembly connector for the material rack is pre-welded to the end of the tube body 4. During connection, the four positioning protrusions 33 are first inserted into one end of the tube body 4, and the four positioning protrusions 33 are precisely positioned against the inner wall of the tube body 4. The end of the square tube body 4 rests against the outer flange 31, and the two are welded together to fix them in place. The dimensional fit is precise, the support strength is higher and more stable, and it is suitable for batch processing.

[0032] Alternatively, the quick-assembly connector of the material rack and the pipe body 4 can be set as a weld-free assembly, but the reinforcing edge 32 and the positioning protrusion 33 need to be designed to be longer along the axial direction to facilitate bolt reinforcement.

[0033] The quick-assembly connector for the material rack is used in the assembly of the material rack. The quick-assembly connector is pre-installed and welded to both ends of the corresponding pipe body 4 to form the splicing pipe. This process can be completed directly after the pipe cutting process, making it convenient. The subsequent assembly of the material rack, such as involving the attached... Figure 5 As shown, two short splicing pipes can be inserted into the assembly holes of two long splicing pipes at both ends. Bolts can be screwed into the internal threaded holes 11 to prevent them from coming loose. Then, short edge rods can be assembled at both ends of the two long splicing pipes. Bolts can also be screwed into the internal threaded holes 11 of the long splicing pipes to prevent them from coming loose. Next, three short splicing pipes and long edge rods can be assembled on the other side of each long splicing pipe. The ends of the long edge rods and the ends of the short edge rods are mortise and tenoned to form the base frame of the material rack. This allows for quick assembly without electricity or fire, which is convenient for the production and manufacturing of material racks. Disassembly and assembly are convenient, and maintenance is easy. If a splicing pipe is damaged, it is also easy to replace.
