Technical Field

[0001] The utility model relates to the technical field of stainless steel pipes, in particular to a bending-resistant stainless steel pipe. Background Art

[0002] Stainless steel pipe is a hollow, long, round steel bar, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures, and is also often used as furniture and kitchen utensils.

[0003] At present, most of the existing stainless steel pipes are single pipe structures. During the transportation process, the surface of the stainless steel pipe is subject to collision and extrusion, which will cause deformation and bending. Once bent or the strength is insufficient, there will be certain safety hazards in use, which will cause great inconvenience to people. Based on this, a bending-resistant stainless steel pipe is proposed. Utility Model Content

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] like Figures 1 to 3 As shown, the bending-resistant stainless steel pipe in this embodiment includes a pipe body 1, which is a stainless steel pipe. Several fixing rings 2 are installed at equal intervals on the surface of the pipe body 1. The fixing ring 2 is circular and is sleeved on the surface of the pipe body 1. Several connecting plates 3 are installed on the surface of the fixing ring 2. The connecting plate 3 is used to connect multiple fixing rings 2. An outer tube 4 is sleeved on the outside of the fixing ring 2. The outer tube 4 is used to protect the outside of the pipe body 1. Several ridges 7 are installed inside the outer tube 4. The number of ridges 7 is multiple. The connecting plate 3 is in contact with the inner wall of the outer tube 4. The ridges 7 can increase the bending resistance of the surface of the outer tube 4. At the same time, the fixing ring 2 and the connecting plate 3 are used to protect the surface of the pipe body 1, which effectively enhances the bending resistance of the stainless steel pipe and avoids affecting the use effect of the stainless steel pipe.

[0022] Specifically, a plurality of mounting grooves 5 are arranged in a circumferential array at equal intervals on the surface of the fixing ring 2. The connecting plate 3 is located in the mounting groove 5, and the upper end of the connecting plate 3 extends to the outside of the mounting groove 5 and contacts the inner wall of the outer tube 4. After the connecting plate 3 is installed in the mounting groove 5, the connecting plate 3 and the fixing ring 2 are connected by welding, so that the fixing ring 2 and the connecting plate 3 form a whole, and the fixing ring 2 and the connecting plate 3 are used to protect the tube body 1, thereby effectively improving the bending resistance of the outside of the tube body 1.

[0023] Furthermore, connecting grooves 6 are provided on the surface of the fixing ring 2 between the mounting grooves 5. The distance between the connecting grooves 6 is consistent with the distance between the mounting grooves 5. The shape and size of the connecting grooves 6 match the shape and size of the connecting plates 3. When the two pipe bodies 1 are connected, a part of the outer tube 4 with excess length can be cut out, and the length of the connecting plate 3 can be retained. Each connecting plate 3 is inserted into the connecting groove 6 respectively to achieve pre-fixation, thereby avoiding gaps caused by misalignment when the pipe bodies 1 are connected.

[0024] Furthermore, the ridges 7 are semicircular and are distributed in a circular array at equal intervals inside the outer tube 4. The ridges 7 are installed outside the outer tube 4. When the outer tube 4 is locally subjected to collision and impact force, the ridges 7 can disperse the local impact on the surface of the outer tube 4, thereby improving the bending resistance of the outer tube 4.

[0025] Furthermore, the ridges 7 are in contact with the surface of the fixing ring 2. When the outer tube 4 and the connecting plate 3 are sleeved together, the fixing ring 2 supports the outer tube 4 through the ridges 7, thereby ensuring the overall structural strength of the stainless steel tube.

[0026] Furthermore, the inner diameter of the fixing ring 2 matches the outer diameter of the tube body 1 , and the fixing ring 2 is sleeved on the surface of the tube body 1 , making it convenient for multiple fixing rings 2 to move on the surface of the tube body 1 .

[0027] The method of use of this embodiment is as follows: during assembly, first place multiple connecting plates 3 inside the installation groove 5 respectively, and fix the connecting plates 3 and the fixing ring 2 by welding, and then sleeve the outer tube 4 on the outside of the connecting plate 3, effectively increasing the bending resistance of the stainless steel tube and improving the overall strength. When it is necessary to connect the two tube bodies 1, cut out a part of the excess length of the outer tube 4 and retain the length of the connecting plate 3, and insert each connecting plate 3 into the connecting groove 6 respectively to achieve pre-fixation, and then weld the tube body 1 and the outer tube 4 respectively to achieve the connection of the stainless steel tube, effectively avoiding gaps due to misalignment.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
