In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0053] like Figures 1 to 14As shown, this embodiment provides a method for designing a drying rack connecting bracket, and the method for designing a drying rack connecting bracket includes the following steps:

[0054] S1: Design the bracket body 1 and the structures at both ends of the bracket body 1 so that multiple bracket bodies 1 can be detachably connected end to end in sequence;

[0055] S2: According to the matching part of the drying net 3, the bayonet 10 on the bracket body 1 is designed so that the matching part of the drying net 3 can be plugged into the bayonet 10, so that the matching part of the drying net 3 can form a layer of the drying rack by matching with the bayonet 10 on multiple bracket bodies 1, and the bracket body 1 of the upper layer is connected with the corresponding bracket body 1 of the lower layer, so that the drying net 3 is stacked into a drying rack.

[0056] Through the above-mentioned design method, the assembly and disassembly of the bracket body 1 and the drying net 3 are relatively convenient, and it is easy to transport. The transportation occupies less space, which is beneficial to saving transportation costs. The required number of layers of drying nets 3 can be stacked according to usage requirements, and the flexibility of use is better. At the same time, the versatility of the bracket body 1 is better, which is convenient for mass production and rapid replacement.

[0057] Specifically, the design of the two end structures of the bracket body 1 includes:

[0058] S11: It is designed that one end of the bracket body 1 is provided with an inner hole 20, and the other end is an insertion end that can be plugged and matched with the inner hole 20; when connecting two bracket bodies 1, it is only necessary to insert the insertion end of one bracket body 1 into the inner hole 20 of the other bracket body 1, which is convenient and fast, saving assembly time, and the plug-in fit makes the connection stability of the two bracket bodies 1 better, and it is not easy to cause displacement on the horizontal plane.

[0059] S12: Design the insertion end, and according to the wall thickness of the inner hole 20, design the outer side of the insertion end to form a step surface 2, so that when the upper and lower layers of the bracket body 1 are connected, one end of the bracket body 1 with the inner hole 20 located in the upper layer abuts against the step surface 2 of the bracket body 1 located in the lower layer. The step surface 2 limits the position of the upper layer of the bracket body 1 to prevent the upper layer of the bracket body 1 from continuously falling and interfering with the bayonet 10 of the lower layer of the bracket body 1, that is, the step surface 2 provides a limiting support function for the upper layer of the bracket body 1.

[0060] The width of the step surface 2 is greater than the wall thickness of the inner hole 20, and the width of the step surface 2 is 1-2 times the wall thickness of the inner hole 20. The wider step surface 2 provides sufficient support surface for the upper layer of the bracket body 1, so that the two bracket bodies 1 are connected stably, and the step surface 2 of appropriate width can prevent the upper layer of the bracket body 1 from having a large displacement in the plane where the step surface 2 is located, which affects the stability.

[0061] More specifically, the design of the bayonet 10 on the bracket body 1 includes:

[0062] S21: Designing the height of the bayonet 10 according to the thickness of the drying net 3 so that the drying net 3 can be smoothly inserted into the bayonet 10 .

[0063] Among them, the height of the bayonet 10 is greater than the thickness of the drying net 3, and the difference between the height of the bayonet 10 and the thickness of the drying net 3 is not greater than 1 mm. That is, the height of the bayonet 10 is substantially consistent with the thickness of the drying net 3, ensuring that the drying net 3 can be smoothly inserted into the bayonet 10 while having good position stability. In this embodiment, the bayonet 10 space is between the bottom of the step surface 2 and the lower wall of the bayonet 10. The step surface 2 also provides a limit in the height direction for the drying net 3, and also makes the assembled multi-layer drying rack structure more compact and has a higher space utilization rate.

[0064] like Figures 2 to 4 As shown, this embodiment also provides a drying rack connecting bracket, which is designed by the above-mentioned drying rack connecting bracket design method, is convenient for separate transportation, and is convenient for rapid assembly with the drying net 3, has better supporting stability and better versatility.

[0065] like Figures 2 to 14 As shown, this embodiment also provides a method for forming a drying rack connecting bracket. Based on the above-mentioned drying rack connecting bracket, the forming method includes the following steps:

[0067] S200: preparing a stamping die 100 and a workpiece 200 to be processed according to a processing drawing and processing parameters;

[0068] S300: placing the workpiece 200 to be processed on the stamping die 100, and stamping the workpiece 200 to be processed to obtain a drying rack connecting bracket.

[0069] Specifically, the processing drawings include drawings of the stamping die 100 and drawings of the workpiece 200 to be processed, and the processing parameters include the size of the stamping die 100 and the size of the workpiece 200 to be processed.

The first step plane section 20212 to be formed and the second step plane section 20222 to be formed are arranged at intervals, so that the first step plane section 20212 to be formed and the second step plane section 20222 to be formed can be bent smoothly during subsequent stamping; the gap between the first guide plane section 20213 and the second guide plane section 20223 can be bent smoothly during subsequent stamping without interfering with each other.

[0071] Optionally, the main body section 201 can be a commercially available metal tube, or can be processed and bent from a metal plate into a tubular structure. The positioning section 202 can be formed by cutting two adjacent surfaces of a rectangular metal tube by wire cutting.
