AI Technical Summary
In the pipe bending process, welding errors can cause the inner surfaces to not make complete contact, resulting in the pipe bending structure being prone to deformation and having insufficient compressive strength after welding.
A protrusion is added to the inner side of the pipe, which extends into the inner cavity of another pipe and abuts against the inner wall through a rubber pad, thereby increasing the contact area and support effect, and improving the welding quality and pressure resistance.
By adding protrusions and rubber pads, the compressive strength of the pipe's angled structure is significantly improved, with the maximum bearing capacity increased by approximately 60.8 kg.

[0026] In order to make the technical content, the purpose and effect of the utility model more clear, the following will be described in detail in combination with the embodiment and the drawings.
[0027] Please refer to Figure 2 or Figure 3As shown, the utility model relates to a pipe angle structure, including two pipes 1, the one end of pipe 1 is welding end along the length direction of itself, the both end surfaces of pipe 1 along the thickness direction of itself are divided into inner side 11 and outer side 12, the welding end of pipe 1 is bevel, to make the length of inner side 11 less than the length of outer side 12, the inner side 11 of at least one pipe 1 is equipped with lug 2, when the welding end of two pipes 1 is butted, the end of inner side 11 of two pipes 1 is abutted, the lug 2 on one pipe 1 is inserted into the inner chamber of another pipe 1.
[0028] Working principle: at least the inner side 11 of one pipe 1 is additionally provided with lug 2, so that when two pipes 1 are butted along the angle line 3 through the welding end, the lug 2 can replace the end of the inner side 11 of the pipe 1 and the end of the inner side 11 of another pipe 1, thereby ensuring the welding quality between the two pipes 1 and improving the compression resistance.
[0029] It is worth mentioning that the two pipes 1 can be a complete pipe, which is provided with a notch on the pipe body to form two pipes 1 sharing the same outer side 12. This form of pipe 1 not only saves the welding of the outer side 12, but also has better compression resistance. Of course, the two pipes 1 can be independent.
[0030] In some embodiments, as shown in Figure 4 or Figure 5 the end of the lug 2 on one pipe 1 away from the inner side 11 abuts against the inner wall of another pipe 1. By supporting the pipe 1 with the lug 2, the compression resistance of the pipe angle structure can be further improved.
[0031] In some embodiments, the thickness of the lug 2 is equal to the wall thickness of the pipe 1. Since the thickness of the lug 2 is equal to the wall thickness of the pipe 1, the shape of the pipe 1 with the lug 2 can be directly cut on the complete pipe, thereby avoiding additional welding of the lug 2.
[0032] In some embodiments, as shown in Figure 3 the inner side 11 of one pipe 1 is provided with a lug 2. The width of the lug 2 can be equal to the width of the pipe 1, which can maximize the contact area between the lug 2 and the end of the inner side 11. Of course, the width of the lug 2 can be less than the width of the pipe 1, which can reduce the weight of the pipe angle structure.
[0033] In some embodiments, as shown in Figure 2 the inner side 11 of two pipes 1 is provided with lugs 2 that are offset from each other. By offsetting the lugs 2 on the two pipes 1, it can be ensured that the lugs 2 will not interfere with each other when the welding ends of the two pipes 1 are spliced along the angle line 3.
[0034] In some implementations, please refer to Figure 4 As shown, the length of the protrusion 2 is equal to the inner thickness of the pipe 1. Using the protrusion 2 to support the pipe 1 can further improve the compressive strength of the pipe's angled structure.
[0035] It is worth noting that both pipes 1 are provided with protrusions 2, and the length of the protrusions 2 is equal to the inner thickness of the pipe 1, which achieves the best support effect.
[0036] In some implementations, please refer to Figure 5 As shown, the length of the protrusion 2 is greater than the inner thickness of the pipe 1. Using the protrusion 2 to support the pipe 1 can further improve the compressive strength of the pipe's angled structure.
[0037] In some embodiments, a rubber pad (not shown in the figure) is provided at the end of the protrusion 2 away from the inner surface 11, and the rubber pad abuts against the inner wall of the pipe 1. The friction and deformation of the rubber pad are used to enhance the deformation resistance of the protrusion 2, thereby further improving the compressive strength of the pipe bend structure.
[0038] In a control experiment, a pipe bend structure was obtained using 40×40mm stainless steel square tubing of the same specifications. The pipe bend structure of this invention employs the following... Figure 2 As shown, the two pipes 1 are provided with staggered protrusions 2. For example... Figure 6 As shown, the maximum load-bearing capacity of a typical pipe with a bend in its structure is 390.31 N, approximately 39.8 kg. Figure 7 As shown, the pipe bend structure of this utility model has a maximum bearing capacity of 596.24N, approximately 60.8kg.
[0039] Based on the above comparative experiments, it can be seen that the pipe bend structure of this utility model has improved its compressive strength.
[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
