[0019] In order to make the technical problems, technical schemes and beneficial effects of the utility model clearer, the utility model is further described in detail below in combination with the drawings and examples.

[0020] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification and claims of the present application are intended to cover the non-exclusive inclusion of the listed steps or elements. For example, a process, method, system, product or device that includes a series of steps or units does not limit the listed steps or units, but optionally also includes steps or units not listed, or optionally also includes other steps or units inherent to such processes, methods, products or devices. The term "arrangement" and other terms should be broadly understood, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium; it can be the internal communication of two elements or the interaction relationship of two elements, unless otherwise explicitly limited. The terms "up", "down", "left", "right", "front", "back", "bottom" and the like indicate the orientation or position based on the orientation or position shown in the drawings, and are only for convenience of description, and cannot be understood as a limitation on the technical solution.

[0021] It should be noted that the pull rod head is a key connecting component in the hardware structure of steel structure, anti-seismic support and photovoltaic support, and its performance directly affects the stability and safety of the overall structure. The traditional pull rod head manufacturing process mainly adopts integral machining or die casting process, which can meet the strength requirements, but there are many problems in actual application, especially in cost and manufacturing cycle.

[0022] Specifically, the traditional integral machining process requires high-precision numerical control machine tools to complete complex cutting and forming operations. This process not only requires large equipment investment, but also has low material utilization rate, resulting in high production cost.

[0023] Secondly, although the die casting process can realize one-time forming of complex shapes, the mold design and manufacturing cycle are long, and the mold cost is high. For small batch or customized production, the economic efficiency of die casting process is poor. At the same time, the selection of materials in the die casting process also has certain limitations, usually specific alloy materials need to be used, which further increases the material cost. In addition, the subsequent processing of die castings (such as deburring, surface treatment, etc.) will also prolong the production cycle.

[0024] As shown in Figs. 1-2 The present embodiment provides a kind of assembled pull rod connector, it is the connecting structure of multiple split parts, it is connected by inserting bayonet and through full welding mode, inserting bayonet is designed before welding to provide accurate positioning, annular weld replaces local welding, ensure that the structure after welding is uniformly stressed, reduce stress concentration, effectively prevent vibration loosening, improve overall carrying capacity, modular design makes each component can be processed in parallel, cooperate with standard bayonet assembly, overall manufacturing cost is low, cycle is short.

[0025] Compared with the manufacturing of traditional machined parts and die-cast parts, high-precision machine tools or complex molds are not required, the equipment investment cost is reduced, and it is especially suitable for small and medium-sized enterprise production.

[0026] Specifically, the assembled pull rod connector includes a pull rod head body 10, which is a connecting structure composed of a plurality of split parts. The parts are matched by inserting the bayonet and connected by full-circle welding to form a threaded end and an action end. The threaded end is used to connect with the pull rod, and the action end is used to connect with external components.

[0027] In one embodiment, the parts include a screw rod 11, a flange 12, and a welding plate 13. The screw rod 11 is used to form a threaded end, the welding plate 13 is used to form an action end, and the flange 12 is used to connect the screw rod 11 and the welding plate 13. The screw rod 11 and the flange 12 are connected by full-circle welding, and the welding plate 13 and the flange 12 are connected by full-circle welding. The contact surfaces of the screw rod 11 and the flange 12, and the welding plate 13 and the flange 12 form uniform and dense welds, significantly improving the tensile strength and torsional performance of the connection site. Specifically, the full-circle welding of the screw rod 11 and the flange 12 forms a rigid connection, ensuring effective transmission of axial tension, and the design of the flange 12 bayonet and the welding plate 13 pin allows uniform distribution of lateral load.

[0028] The flange 12 is provided with a first bayonet 121 and a second bayonet 122. One end of the screw rod 11 is inserted into the first bayonet 121, and the pin of the welding plate 13 is inserted into the second bayonet 122. By having flanges 12 or welding plates 13 with different sizes of first bayonets 121 and second bayonets 122, the connector size can be quickly adjusted to meet the needs of external components of different sizes.

[0029] The welding plate 13 is one or two. The action end uses single or double plate configuration to flexibly meet the needs of single side fixation (such as wall installation) or double side clamping (such as beam body connection), and the through hole 131 design realizes multidirectional positioning to meet different bearing requirements.

[0030] The welding plate 13 is provided with a through hole 131.

[0031] The screw rod 11 is provided with a nut and a washer. The nut and the washer form a mechanical anti-loose mechanism to reduce the risk of thread loosening.

[0032] In one embodiment, the welding method includes one or more combinations of arc welding, gas shielded welding or laser welding. Arc welding is suitable for low-cost mass production, with a welding speed of up to 15-30 cm / min; gas shielded welding (such as MIG / MAG) has more stable weld quality and is suitable for automated production; laser welding has the highest precision and is suitable for precision connections; the combination of multiple welding processes can achieve the best results, for example, laser welding is used in key load-bearing parts to ensure strength, and arc welding is used in non-critical areas to reduce costs, which can improve the overall welding efficiency and improve the comprehensive utilization rate of equipment.

[0033] In one embodiment, the parts are made of sheet metal or general-purpose parts. Compared with traditional machined parts and die-cast parts, the parts are made of sheet metal or general-purpose parts, which are used as raw materials and can be formed through simple processes such as cutting and stamping, with higher material utilization and ease of processing, thereby directly and indirectly reducing manufacturing costs and improving production efficiency.
