Description

Technical Field

[0001] This utility model relates to the field of nine-fold profile cabinets, and specifically to a nine-fold profile cabinet formed by corner welding. Background Technology

[0002] Nine-fold profile cabinets are widely used in electronic equipment storage, industrial control, and other fields due to their excellent strength and stability. Traditional nine-fold profile cabinets typically use complex and material-intensive T-joint components at the eight corners to connect the rods in each direction. This T-joint structure not only consumes a large amount of raw materials, increasing production costs, but also, due to its complex structure, requires multiple processing steps, resulting in high processing difficulty and low production efficiency, which is detrimental to the rapid production and large-scale application of the cabinets. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides a nine-fold profile cabinet with corner welding.

[0004] The purpose of this utility model can be achieved through the following technical solution: A nine-fold profile cabinet with corner welding includes: four rods arranged along the depth direction, four rods arranged along the width direction, and four rods arranged along the height direction.

[0005] The cabinet has eight corners, and the first, second, and third ends of the rods at each corner cooperate to form a cavity. The cavity is fixedly connected inside and out by multi-point welding, so that the first, second, and third rods are connected to each other to form the cabinet frame. A square nut is provided in the cavity, and the square nut has a threaded hole inside.

[0006] In a further improvement, the end of rod one is provided with a first contouring head, the end of rod two is provided with a second contouring head, and the end of rod three is provided with a third contouring head. The first, second, and third contouring heads cooperate with each other at each corner to form a cavity. The left inner side of the first contouring head is the left inner surface of the cavity, the front inner side of the second contouring head is the front inner surface of the cavity, and the third contouring head has an L-shaped cross-section, with its inner side forming the rear and right inner surfaces of the cavity. The first contouring head is located to the left and rear of the second contouring head and to the left of the third contouring head. The second contouring head is located to the right and front of the first contouring head and to the front of the third contouring head. The third contouring head is located to the right of the first contouring head and to the rear of the second contouring head. Adjacent positions of the rod one, rod two, rod three, first contouring head, second contouring head, and third contouring head are connected by welding.

[0007] In a further improvement, the end of the rod body three is provided with a contour head four, the cavity is located inside the contour head four, the front end face of the rod body one is located on the rear side of the contour head four, the left end face of the rod body two is located on the right side of the contour head four, and the adjacent positions of the rod body one, rod body two, rod body three and contour head four are connected by welding.

[0008] A further improvement is that modular holes are evenly spaced on rod one, rod two, and rod three. Compared with the prior art, the beneficial effects of the nine-fold profile cabinet with corner welding of this utility model are:

[0009] Abandoning the complex T-joint components used in traditional nine-fold profile cabinet corners, this design incorporates contour head one, contour head two, and contour head three at the ends of rod one, rod two, and rod three, with the three contour heads working together to form a cavity; alternatively, a contour head four with a cavity is separately installed at the end of rod three, working in conjunction with adjacent rod one and rod two. Both methods achieve the connection of the three rods through multi-point welding, simplifying the connection structure at the cabinet corners, reducing raw material usage, and lowering manufacturing difficulty and cost. Multi-point welding makes the corner connection more robust, enhancing the overall structural strength and stability of the cabinet and better protecting the internal equipment.

[0019] The following describes the embodiments and appendices. Figures 1-7 The technical solution of this utility model will be further described below.

[0020] Example 1

[0021] A nine-fold profile cabinet with corner welded structure includes: four rods 11 arranged along the depth direction, four rods 12 arranged along the width direction, and four rods 13 arranged along the height direction.

[0022] The cabinet frame 1 has eight corners. The ends of rod 11, rod 2, and rod 3 at each corner cooperate to form a cavity 14. The cavity 14 is fixedly connected inside and out by multi-point welding, so that rod 11, rod 2, and rod 3 13 are connected to each other to form the cabinet frame 1. A square nut 15 is provided in the cavity 14, and the square nut 15 has a threaded hole 151 inside.

[0023] The end of rod 11 is provided with a contour head 111, the end of rod 12 is provided with a contour head 121, and the end of rod 13 is provided with a contour head 131. The contour heads 111, 121, and 131 cooperate with each other at each corner to form a cavity 14. The left inner side of the contour head 111 is the left inner side of the cavity, the front inner side of the contour head 121 is the front inner side of the cavity, and the contour head 131 has an L-shaped cross-section and its inner side is the rear inner side of the cavity 14. The first and right inner surfaces of the contouring head 111 are located to the left and rear of the second contouring head 121 and to the left of the third contouring head 131. The second contouring head 121 is located to the right and front of the first contouring head 111 and to the front of the third contouring head 131. The third contouring head 131 is located to the right of the first contouring head 111 and to the rear of the second contouring head 121. The adjacent positions of the various structures of the first rod 11, the second rod 12, the third rod 13, the first contouring head 111, the second contouring head 121, and the third contouring head 131 are connected by welding.

[0024] like Figures 1-4 As shown, when traditional server racks use T-joints for connection, the connection between the T-joint and each rod relies on a limited number of connection points, resulting in a relatively simple connection method and uneven stress distribution. In this embodiment, however, the contoured heads of the three rods cooperate to form a cavity, and the shape design of the contoured heads significantly increases the contact area between them. Multi-point welding allows for fixing the profiles at multiple locations, ensuring the welding points are evenly distributed on the inner and outer sides of the contoured heads. When the rack is subjected to external forces, these evenly distributed welding points disperse the force throughout the corner structure, avoiding localized stress concentration and thus enhancing the overall structural strength and stability of the rack. Compared to traditional racks using T-joints, this embodiment eliminates the complex and material-intensive T-joint, reducing raw material usage and lowering manufacturing difficulty and cost. Simultaneously, the multi-point welding method improves the robustness of the corner connections, making the rack more stable and reliable during use, and better protecting the internal equipment.

[0025] The specific shapes and positional relationships of the three contouring heads allow them to precisely fit together to form a regular cubic cavity. This precise fit not only ensures the square nut is securely installed within the cavity but also guarantees accurate welding positions between the contouring heads during the welding process, resulting in evenly distributed weld points around the cavity. The shape design of the contouring heads also considers force transmission paths. When the cabinet is subjected to external forces, the force can be transmitted along a reasonable path through the connections between the contouring heads, further enhancing the stability of the corner structure.

[0026] In conventional server rack structures, handling and securing the rack typically requires complex additional connection structures, increasing costs and making installation inconvenient. In this embodiment, the cubic cavity formed by the contoured head is perfectly sized and shaped to fit a square nut. Installing the square nut within the cavity, the threaded hole provides a standard interface for connecting the rack to other equipment or handling tools. The engagement of bolts with the threaded holes facilitates easy securing and handling of the rack. This design utilizes the space at the corner of the rack, integrating connection functionality into the corner.

[0027] Example 2

[0028] A nine-fold profile cabinet with corner welded structure includes: four rods 11 arranged along the depth direction, four rods 12 arranged along the width direction, and four rods 13 arranged along the height direction.

[0029] The cabinet frame 1 has eight corners. The ends of rod 11, rod 2, and rod 3 at each corner cooperate to form a cavity 14. The cavity 14 is fixedly connected inside and out by multi-point welding, so that rod 11, rod 2, and rod 3 13 are connected to each other to form the cabinet frame 1. A square nut 15 is provided in the cavity 14, and the square nut 15 has a threaded hole 151 inside.

[0030] The end of the rod body 13 is provided with a contour head 16. The cavity 14 is located inside the contour head 16. The front end face of the rod body 11 is located on the rear side of the contour head 16. The left end face of the rod body 212 is located on the right side of the contour head 16. The adjacent positions of the rod body 11, rod body 212, rod body 13 and contour head 16 are connected by welding.

[0031] like Figures 5-7As shown, in the corner-welded nine-fold profile cabinet of Embodiment 2, a stable connection of the cabinet frame is achieved through an innovative design of the end structure of the rods. Specifically, a specific cavity 14 structure is constructed using the contour head 16 at the end of rod three 13 to accommodate the ends of rod one 11 and rod two 12. The front end face of rod one 11 fits against the rear side of contour head 16, and the left end face of rod two 12 fits against the right side of contour head 16. The three are firmly connected through multi-point welding at adjacent positions. This connection method abandons the traditional complex T-joint components and instead adopts a direct rod end fit and welding process, simplifying the manufacturing process; the multi-point welding method forms a stable stress-bearing structure at the corner. When the cabinet is subjected to external force, the external force can be effectively distributed to the entire corner area through the evenly distributed welding points between rod one 11, rod two 12 and contour head 16. The unique shape design of the contour head 416 allows it to guide the force transmission path effectively, avoiding localized stress concentration, thereby enhancing the overall deformation resistance and load-bearing capacity of the cabinet.

[0032] As a further preferred embodiment, modular holes 21 are evenly spaced on the first rod 11, the second rod 12, and the third rod 13. The modular holes 21 provide standard installation positions for various accessories installed in the cabinet.

[0033] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
