It is expressly understood that any of the embodiments described herein can be incorporated into any other embodiment.

[0029] In order to make the technical personnel in the field of the present application better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings.

[0030] Reference Figure 1 and Figure 2The utility model discloses an embodiment discloses a foot stand support metal pipe, including metal pipe body 1 and interface part 2, metal pipe body 1 is hollow tubular structure, the pipe wall of metal pipe body 1 is single layer metal layer, metal pipe body 1 includes the pipe body first end 101 and pipe body second end 102, interface part 2 includes interface part first end 201 and interface part second end 202, interface part 2 includes two metal layers, the pipe body first end 101 with the interface part first end 201 one layer metal layer integral connection, two metal layers are integrally connected in interface part second end 202.

[0031] The foot stand support metal pipe of the embodiment aims to solve the problems of virtual welding and welding through in the welding process of thin-walled steel pipes.

[0032] The metal pipe body 1 adopts a hollow tubular structure, and the pipe wall is a single layer metal layer. The material can be selected from high-strength and good-welding steel materials, such as stainless steel or carbon steel, etc.

[0033] The interface part 2 is used for welding connection with other structural components. The interface part 2 includes an interface part first end 201 and an interface part second end 202, and adopts a two-layer metal layer structure as a whole. The purpose is to increase the thickness and strength of the welding area, improve the quality of the welding joint, and effectively avoid the problems of virtual welding and welding through.

[0034] The interface part first end 201 and the pipe body first end 101 of the metal pipe body 1 are integrally connected through a layer of metal layer. At the interface part second end 202, two layers of metal layers are integrally connected. This special structure is formed by stamping one end of the hollow metal pipe by a stamping device. The single layer metal layer of a certain length at the end is folded inward into the metal pipe and is extruded, so that the two layers of metal layers are tightly attached to form the thickened interface part 2. Due to the two-layer metal layer structure of the interface part 2, the welding position can have higher fusion strength and greater heat capacity. This not only can effectively resist the thermal stress in the welding process and prevent welding through, but also can ensure the integrity and sealing of the weld, and avoid the occurrence of virtual welding phenomenon. At the same time, due to the design of the interface part 2, the image features of the welding area of the foot stand support metal pipe are more obvious, and the robot is more easy to identify the welding position when performing welding operation, thereby improving the welding efficiency.

[0035] In one specific embodiment, the pipe body first end 101 and the outer layer metal layer of the interface part first end 201 are integrally connected. In one specific embodiment, the pipe body first end 101 and the inner layer metal layer of the interface part first end 201 are integrally connected. It can be understood that this can be adjusted by controlling the direction of folding the end metal pipe when stamping one end of the metal pipe during the processing of the foot stand support metal pipe.

[0036] In one embodiment, the thickness of the single layer of metal is less than or equal to 1 mm.

[0037] In this embodiment, by controlling the thickness of the single layer of metal to be within 1 mm, the overall weight of the metal tube can be significantly reduced while maintaining sufficient structural strength; and the metal tube is easy to bend and shape, reducing material costs and improving overall production efficiency and cost-effectiveness.

[0038] In one embodiment, the width of the interface portion 2 is greater than or equal to 1 mm and less than or equal to 10 mm. The width is defined as the dimension in the direction from the first end 201 of the interface portion to the second end 202 of the interface portion.

[0039] In this embodiment, the width of the interface portion directly affects the strength and stability of the welded joint. Too narrow a width can cause the welded joint to fail easily when subjected to external forces, while too wide a width can affect the appearance of the product. Therefore, by controlling the width of the interface portion to be within the range of 1 mm to 10 mm, the welded joint can be ensured to have sufficient strength and stability while ensuring the product to have an attractive appearance. Specifically, different application scenarios have different requirements for the size and shape of the foot support metal tube, and the above-mentioned width range can flexibly adapt to various connection requirements.

[0040] Referring to Figure 2 In one embodiment, at least part of the interface portion 2 near the second end 202 of the interface portion is folded outward to form an outward folding area 203, and the outer diameter of the outward folding area 203 is greater than the outer diameter of the metal tube body 1.

[0041] In this embodiment, at least part of the interface portion 2 near the second end 202 of the interface portion is folded outward to form a distinct outward folding area. The formation of the outward folding area 203 further increases the thickness of the interface portion 2, thereby enhancing the welding strength that the interface portion 2 can withstand. In addition, the outer diameter of the outward folding area 203 is greater than the outer diameter of the metal tube body 1, thereby providing a larger contact area when connecting the foot support metal tube with other components, which can serve as a positioning or guiding structure before welding, improving the tightness of the foot support metal tube and other components when placed together, thereby further increasing the stability and reliability of the welding. Specifically, when processing the outward folding area 203, the upper area of the interface portion 2 formed by the double layer of metal in the previous embodiment can be further folded outward by a stamping device to form the outward folding area 203 as shown in Figure 2 The end surface of the outward folding area 203 can be arc-shaped.

[0042] In one embodiment, the difference between the outer diameter of the outward folding area 203 and the outer diameter of the metal tube body 1 is greater than or equal to the thickness of two layers of the single layer of metal.

[0043] In this embodiment, by ensuring that the difference in outer diameter between the everted zone 203 and the metal pipe body 1 is at least the thickness of two single-layer metal layers, the structural reinforcement effect of the everted zone 203 is further enhanced, enabling it to withstand greater welding strength.

[0044] In one specific embodiment, the width of the everted zone 203 is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0045] In this embodiment, the everted zone 203 within the above-mentioned width range is easy to process and maintains the required strength and stability of the everted zone 203, and ensures its visual aesthetics.

[0046] Referring to Figure 2 In one specific embodiment, the foot support metal pipe is used for welding to the outer side of a cylindrical metal pipe, and the second end 202 of the interface portion is a curved surface that fits the outer side of the cylindrical metal pipe of a predefined diameter.

[0047] In this embodiment, the foot support metal pipe is generally designed for welding to the outer side of a cylindrical metal pipe to provide additional support or connection functions. Further, the end surface of the second end 202 of the interface portion is provided as a curved surface to closely fit the local area of the outer side of the cylindrical metal pipe of a predefined diameter, greatly improving the fit and further facilitating the completeness of the welding and reducing the occurrence of welding defects. The above-mentioned predefined diameter is the diameter of the cylindrical metal pipe, which can be determined according to the specific use scenario.

[0048] Referring to Figure 2 In one specific embodiment, at least part of the area of the interface portion 2 near the everted zone 203 is provided with a crimping zone 204.

[0049] In this embodiment, the crimping zone 204 is provided to facilitate adjustment of the bending degree of the curved surface of the second end 202 of the interface portion, so that it can better adapt to cylindrical metal pipes of different shapes. Similarly, the crimping zone 204 can be formed by inwardly extruding the interface portion 2 by a stamping device.

[0050] Referring to Figure 3 In one specific embodiment, the metal pipe body 1 includes a first bending portion 103 and a second bending portion 104 connected to each other, the first bending portion 103 is near the first end 101 of the pipe body, and the second bending portion 104 is near the second end 102 of the pipe body, and the included angle formed between the first bending portion 103 and the second bending portion 104 ranges from 100° to 160°.

[0051] In this embodiment, by adjusting the included angle between the first bending part 103 and the second bending part 104, the foot support metal pipe can better adapt to different installation environments and space limitations, and improve its practicability and flexibility.

[0052] With reference to Figure 4 The embodiment of the utility model discloses a metal foot support, which comprises a foot support body 11 and a foot support metal pipe 22 of the aforementioned embodiment, and the interface part 2 of the foot support metal pipe 22 is welded to the outer side wall of the foot support body 11.

[0053] The metal foot support in the embodiment comprises a foot support body 11, which is the main structure of the entire foot support and can be made of high-strength metal materials such as stainless steel or carbon steel. In actual application, the foot support body 11 can be designed into different shapes and sizes according to specific requirements, such as a tripod, a quadruped or a multi-legged foot support, to meet the use requirements in different scenarios. The foot support metal pipe 22 is used in a corresponding number according to the design requirements of the foot support body 11. The interface part 2 of the foot support metal pipe 22 is welded to the outer side wall of the foot support body 11. The foot support metal pipe 22 with the structure of the aforementioned embodiment has high quality and reliability of the welding joint, high processing efficiency and low production cost.
